CAUTION

During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle. Failure to follow these recom-
mendations may result in shortened engine
life and reduced engine performance.

• Avoid driving for long periods at constant

speed, either fast or slow, and do not run
the engine over 4,000 rpm.

• Do not accelerate at full throttle in any

gear.

• Avoid quick starts.
• Avoid hard braking as much as possible.
• Do not tow a trailer for the first 500 miles

(805 kilometers). Your engine, axle or other
parts could be damaged.

Follow these easy-to-use Fuel Efficient Driv-
ing Tips to help you achieve the most fuel
economy from your vehicle.

1.

Use Smooth Accelerator and Brake Pedal
Application

• Avoid rapid starts and stops.
• Use smooth, gentle accelerator and

brake application whenever possible.

• Maintain constant speed while com-

muting and coast whenever possible.

2.

Maintain Constant Speed

• Look ahead to try and anticipate and

minimize stops.

• Synchronizing your speed with traffic

lights allows you to reduce your number
of stops.

• Maintaining a steady speed can mini-

mize red light stops and improve fuel
efficiency.

3.

Use Air Conditioning (A/C) at Higher Ve-
hicle Speeds

• Below 40 mph (64 km/h), it is more

efficient to open windows to cool the
vehicle due to reduced engine load.

• Above 40 mph (64 km/h), it is more

efficient to use A/C to cool the vehicle
due to increased aerodynamic drag.

BREAK-IN SCHEDULE

FUEL EFFICIENT DRIVING TIPS

5-144

Starting and driving

• Recirculating the cool air in the cabin

when the A/C is on reduces cooling
load.

4.

Drive

at

Economical

Speeds

and

Distances

• Observing the speed limit and not ex-

ceeding 60 mph (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.

• Maintaining a safe following distance

behind other vehicles reduces unneces-
sary braking.

• Safely monitoring traffic to anticipate

changes in speed permits reduced brak-
ing and smooth acceleration changes.

• Select a gear range suitable to road

conditions.

5.

Use Cruise Control

• Using cruise control during highway

driving helps maintain a steady speed.

• Cruise control is particularly effective in

providing fuel savings when driving on
flat terrains.

6.

Plan for the Shortest Route

• Utilize a map or navigation system to

determine the best route to save time.

7.

Avoid Idling

• Shutting off your engine when safe for

stops exceeding 30–60 seconds saves
fuel and reduces emissions.

8.

Buy an Automated Pass for Toll Roads

• Automated passes permit drivers to use

special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.

9.

Winter Warm Up

• Limit idling time to minimize impact to

fuel economy.

• Vehicles typically need no more than 30

seconds of idling at start-up to effec-
tively circulate the engine oil before
driving.

• Your vehicle will reach its ideal operat-

ing temperature more quickly while driv-
ing versus idling.

10.

Keeping your Vehicle Cool

• Park your vehicle in a covered parking

area or in the shade whenever possible.

• When entering a hot vehicle, opening

the windows will help to reduce the in-
side temperature faster, resulting in re-
duced demand on your A/C system.

• Keep your engine tuned up.
• Follow

the

recommended

scheduled

maintenance.

• Keep the tires inflated to the correct pres-

sure. Low tire pressure increases tire wear
and lowers fuel economy.

• Keep all the wheels in correct alignment.

Improper alignment increases tire wear and
lowers fuel economy.

• Use the recommended viscosity engine oil.

For additional information, see “Engine oil
and oil filter recommendations” (P. 10-6).

If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.

If the AWD error warning message is dis-
played, there may be a malfunction in the
Intelligent AWD system. Reduce vehicle
speed and have your vehicle checked as soon
as possible. It is recommended that you visit
an INFINITI retailer for this service.

The AWD high temperature message may be
displayed while trying to free a stuck vehicle
due to increased oil temperature. The driving
mode may change to 2-Wheel Drive (2WD).
If this message is displayed, stop the vehicle
with the engine idling, as soon as it is safe to
do so. Then if the message turns off, you can
continue driving.

The tire size message may be displayed if
there is a large difference between the diam-
eters of front and rear wheels. Pull off the
road in a safe area, with the engine idling.
Check that all tire sizes are the same, that the
tire pressure is correct and that the tires are
not excessively worn.

If any warning messages continue to be dis-
played, have your vehicle checked as soon as
possible. It is recommended that you visit an
INFINITI retailer for this service.

INTELLIGENT ALL-WHEEL DRIVE
(AWD) (if so equipped)

5-146

Starting and driving

WARNING

•

Do not drive beyond the performance ca-
pability of the tires. Accelerating quickly,
sharp steering maneuvers or sudden
braking may cause loss of control, even
with Intelligent AWD engaged.

•

For AWD equipped vehicles, do not at-
tempt to raise two wheels off the ground
and shift the transmission to any drive or
reverse position with the engine running.
Doing so may result in drivetrain damage
or unexpected vehicle movement which
could result in serious personal injury or
vehicle damage.

•

Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure that you inform the
test facility personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious personal in-
jury or vehicle damage.

CAUTION

•

Do not operate the engine on a free roller
when any of the wheels are raised.

•

If you use the free roller, rotate four
wheels with the same speed without
raising any wheels.

•

If an AWD warning message is displayed
while driving there may be a malfunction
in the AWD system. Reduce the vehicle
speed immediately and have your vehicle
checked as soon as possible. It is recom-
mended that you visit an INFINITI re-
tailer for this service.

•

The powertrain may be damaged if you
continue driving when the AWD tem-
perature or tire size incorrect messages
are displayed.

•

If the AWD high temperature message is
displayed while you are driving, pull off
the road in a safe area, and idle the en-
gine. The driving mode will change to
2WD to prevent the AWD system from
malfunctioning. If the warning message
turns off, you can drive again.

•

If the tire size incorrect message is dis-
played while you are driving, pull off the
road in a safe area with the engine idling.
Check that all tire sizes are the same,
that the tire pressure is correct and that
the tires are not excessively worn.

•

If a warning message continues to be dis-
played after the above operations, have
your vehicle checked as soon as possible.
It is recommended that you visit an
INFINITI retailer for this service.

Starting and driving

5-147

WARNING

•

Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.

•

Safe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park). Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and re-
sult in an accident. Make sure the shift
lever has been pushed as far forward as it
can go and cannot be moved without de-
pressing the foot brake pedal.

•

Never leave the engine running while the
vehicle is unattended.

•

Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or make the
vehicle move. Unattended children could
become involved in serious accidents.

•

To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm day
can quickly become high enough to cause
a significant risk of injury or death to
people and pets.

1. Apply the electronic parking brake.

2. Press the Park button to place the vehicle

in the P (Park) position.

3. To help prevent the vehicle from rolling

into traffic when parked on an incline, it is
a good practice to turn the wheels as
illustrated.

ELECTRIC POWER STEERING
TYPE

WARNING

•

If the engine is not running or is turned
off while driving, the power assist for the
steering will not work. Steering will be
harder to operate.

•

When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of the
vehicle, but the steering will be harder to
operate. Have the power steering sys-
tem checked. It is recommended that you
visit an INFINITI retailer for this service.

The power steering system is designed to
provide power assist while driving to operate
the steering wheel with light force.

When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assist for the
steering wheel will be reduced. This is to pre-
vent overheating of the power steering sys-
tem and protect it from getting damaged.
While the power assist is reduced, steering
wheel operation will become heavy. When
the temperature of the power steering sys-
tem goes down, the power assist level will

return to normal. Avoid repeating such steer-
ing wheel operations that could cause the
power steering system to overheat.

You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.

If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the power steering system is not func-
tioning properly and may need servicing.
Have the power steering system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.

When the power steering warning light illu-
minates with the engine running, there will be
no power assist for the steering, but you will
still have control of the vehicle. At this time,
greater steering effort is required to operate
the steering wheel, especially in sharp turns
and at low speeds.

For additional information, see “Power steer-
ing warning light” (P. 2-16).

DIRECT ADAPTIVE STEERING®
TYPE

WARNING

•

When the power steering warning light
illuminates with the engine running, the
power assist for the steering will cease
operation. You will still have control of
the vehicle, but the steering will be
harder to operate.

•

If wheels or tires other than the INFINITI
recommended ones are used, Direct
Adaptive Steering® may not operate
properly and the power steering warning
light may illuminate.

•

Do not modify the vehicle’s suspension
parts such as shock absorbers, struts,
springs, stabilizer bars, bushings and
wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, Direct Adaptive Steering may not
operate properly and the power steering
warning light may illuminate.

•

Do not modify the vehicle’s steering. If
steering parts are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, Direct Adaptive Steering
may not operate properly and the power
steering warning light may illuminate.

•

If the Vehicle Dynamic Control (VDC)
OFF indicator light illuminates, the
power steering warning light may also
illuminate at the same time. Stop the ve-
hicle in a safe location, turn the engine
off and restart the engine. If the power
steering warning light continues to illu-
minate, have the system checked. It is
recommended that you visit an INFINITI
retailer for this service. For additional in-
formation, see “Vehicle Dynamic Control
(VDC) system” (P. 5-154).

CAUTION

•

Do not place the ignition switch in the
ON position while the steering wheel or a
tire is removed.

•

Do not turn the steering wheel as much
as possible while the ignition switch is
any position other than the ON position.

•

Installing an accessory on the steering
wheel, or changing the steering wheel,
may reduce the steering performance.

Direct Adaptive Steering is designed to con-
trol the steering force and steering angle ac-
cording to the vehicle speed and amount of
turning of the steering wheel.

The steering characteristic can be selected
using the INFINITI Drive Mode Selector. For
additional information, see “INFINITI Drive
Mode Selector” (P. 2-22).

If the VDC system is turned off, the setting of
steering becomes Standard mode.

If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate that Direct Adaptive Steering is not
functioning properly and may need servicing.
Have the system checked. It is recommended
that you visit an INFINITI retailer for this
service. For additional information, see
“Power steering warning light” (P. 2-16)

When the power steering warning light illu-
minates with the engine running, the power
assist for the steering will cease operation.
You will still have control of the vehicle. How-
ever, greater steering effort will be needed,
especially in sharp turns and at low speeds.

If Direct Adaptive Steering is malfunctioning,
the steering wheel may turn slightly even
when driving on a straight road.

Under the following conditions, the steering
wheel may turn slightly even when driving on
a straight road. This is due to a protection
mechanism for Direct Adaptive Steering. The

5-150

Starting and driving

steering wheel will return to the normal posi-
tion after the protection mechanism is
deactivated.

Condition A:

• When the engine is stalled or likely to be

stalled

• When the steering wheel is held in the full

lock position or when the front tire touches
an obstruction

• When the battery is discharged

To return the steering wheel to the normal
position, stop the vehicle in a safe location
and stop operating the steering wheel. Then
drive the vehicle for a short period of time.

Condition B:

• When the steering wheel is operated re-

peatedly or continuously while parking or
driving at a very low speed. In this case, the
power assist for the steering wheel will be
reduced.

To return the steering wheel to the normal
position, stop the vehicle in a safe location
and wait for a period of time, without oper-
ating the steering wheel, until the tempera-
ture of Direct Adaptive Steering cools down.
Avoid repeated steering wheel operations
that could cause Direct Adaptive Steering to
overheat.

When the vehicle is tested on the 2–wheel
dynamometer, the power steering warning
light may illuminate. To turn off the power
steering warning light, stop the vehicle in a
safe location, turn the engine off, restart the
engine, and then drive the vehicle for a period
of time.

The following conditions do not indicate a
malfunction of Direct Adaptive Steering:
• You may notice wider steering play when

the ignition switch is in the OFF or AUTO
ACC position compared to when it is in the
ON position.

• After the engine is started, the steering

wheel may turn slightly even when driving a
straight road. To return to the normal posi-
tion, drive the vehicle on a straight road for
a period of time.

• After the engine is started, the steering

wheel may move if the steering wheel was
turned to the fully locked position while the
ignition switch was in the OFF position.

• After the vehicle is tested on the 4–wheel

dynamometer, the steering wheel may turn
slightly even when driving on a straight
road. To return the steering wheel to the
normal position, drive the vehicle on a
straight road for a period of time.

You may hear a noise under the following
conditions. However, this is not a malfunc-
tion.
• When the engine is started or stopped.
• When the steering wheel is turned in the full

lock position.

Starting and driving

5-151

The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will
still have braking at two wheels.

BRAKE PRECAUTIONS

Vacuum assisted brakes

The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on the
brake pedal will be required to stop the ve-
hicle and stopping distance will be longer.

Using the brakes

Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.

To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down
a slope or long grade. Overheated brakes
may reduce braking performance and could
result in loss of vehicle control.

WARNING

•

While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.

•

If the engine is not running or is turned
off while driving, the power assist for the
brakes will not work. Braking will be
harder.

Wet brakes

When the vehicle is washed or driven through
water, the brakes may get wet. As a result,
your braking distance will be longer and the
vehicle may pull to one side during braking.

To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function correctly.

Parking brake break-in

Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or rotors are replaced, in order to
assure the best brake performance.

This procedure is described in the INFINITI
Service Manual. It is recommended that you
visit an INFINITI retailer for this service.

ANTI-LOCK BRAKING SYSTEM
(ABS)

WARNING

•

The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping distances may also be longer on
rough, gravel or snow covered roads, or
if you are using tire chains. Always main-
tain a safe distance from the vehicle in
front of you. Ultimately, the driver is re-
sponsible for safety.

•

Tire type and condition may also affect
braking effectiveness.

–

When replacing tires, install the

specified size of tires on all four
wheels.

BRAKE SYSTEM

5-152

Starting and driving

–

When installing a spare tire, make

sure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, see “Tire and Loading In-
formation label” (P. 8-28).

–

For

additional

information,

see

“Wheels and tires” (P. 8-27).

The ABS controls the brakes so the wheels do
not lock during hard braking or when braking
on slippery surfaces. The system detects the
rotation speed at each wheel and varies the
brake fluid pressure to prevent each wheel
from locking and sliding. By preventing each
wheel from locking, the system helps the
driver maintain steering control and helps to
minimize swerving and spinning on slippery
surfaces.

Using the system

Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to pre-
vent the wheels from locking up. Steer the
vehicle to avoid obstacles.

WARNING

Do not pump the brake pedal. Doing so may
result in increased stopping distances.

Self-test feature

The Anti-lock Braking System (ABS) includes
electronic sensors, electric pumps, hydraulic
solenoids and a computer. The computer has
a built-in diagnostic feature that tests the
system each time you start the engine and
move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in
the brake pedal. This is normal and does not
indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then op-
erates

normally

but

without

anti-lock

assistance.

If the ABS warning light illuminates during
the self-test or while driving, have the vehicle
checked. It is recommended that you visit an
INFINITI retailer for this service.

Normal operation

The Anti-lock Braking System (ABS) operates
at speeds above 3 - 6 mph (5 - 10 km/h). The
speed varies according to road conditions.

When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsation
in the brake pedal and hear a noise from
under the hood or feel a vibration from the
actuator when it is operating. This is normal
and indicates that the ABS is operating prop-
erly. However, the pulsation may indicate
that road conditions are hazardous and extra
care is required while driving.

BRAKE ASSIST

When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even with
light pedal force.

Starting and driving

5-153

WARNING

The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the driv-
er’s responsibility to stay alert, drive safely
and be in control of the vehicle at all times.

The VDC system uses various sensors to
monitor driver inputs and vehicle motion. Un-
der certain driving conditions, the VDC sys-
tem helps to perform the following functions:
• Controls brake pressure to reduce wheel

slip on one slipping drive wheel so power is
transferred to a non-slipping drive wheel
on the same axle.

• Controls brake pressure and engine output

to reduce drive wheel slip based on vehicle
speed (traction control function).

• Controls

brake

pressure

at

individual

wheels and engine output to help the driver
maintain control of the vehicle in the fol-
lowing conditions:

Understeer (vehicle tends to not follow the
steered path despite increased steering input)
Oversteer (vehicle tends to spin due to certain
road or driving conditions)

The VDC system can help the driver to main-
tain control of the vehicle, but it cannot pre-
vent loss of vehicle control in all driving
situations.

When the VDC system operates, the
indicator light in the instrument panel flashes
to note the following:
• The road may be slippery or the system may

determine some action is required to help
keep the vehicle on the steered path.

• You may feel a pulsation in the brake pedal

and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.

• Adjust your speed and driving to the road

conditions.

For additional information, see “Slip indicator
light” (P. 2-16) and ”Vehicle Dynamic Control
(VDC) OFF indicator light” (P. 2-17).

If a malfunction occurs in the system, the

and

indicator lights come on in the

instrument panel. The VDC system automati-
cally turns off when these indicator lights are
on.

The lower display is used to turn off the VDC
system. When the VDC system is turned off,
the

indicator light, the RAB system

warning light, and the FEB with Pedestrian
Detection system warning light illuminate to
indicate the VDC, FEB with Pedestrian De-
tection, and RAB systems are off.

When the lower display is used to turn off the
system, the VDC system still operates to pre-
vent one drive wheel from slipping by trans-
ferring power to a non-slipping drive wheel.
The

indicator light flashes if this occurs.

All other VDC functions are off and the
indicator light will not flash.

VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM

5-154

Starting and driving

The VDC system is automatically reset to on
when the ignition switch is placed in the OFF
position then back to the ON position.

The computer has a built-in diagnostic fea-
ture that tests the system each time you start
the engine and move the vehicle forward or in
reverse at a slow speed. When the self-test
occurs, you may hear a clunk noise and/or
feel a pulsation in the brake pedal. This is
normal and is not an indication of a
malfunction.

WARNING

•

The VDC system is designed to help the
driver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving tech-
niques. Reduce vehicle speed and be es-
pecially careful when driving and corner-
ing on slippery surfaces and always drive
carefully.

•

Do not modify the vehicle's suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI

WARNING

•

The VDC system is designed to help the
driver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving tech-
niques. Reduce vehicle speed and be es-
pecially careful when driving and corner-
ing on slippery surfaces and always drive
carefully.

•

Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
recommended for your vehicle or are ex-
tremely deteriorated, the VDC system
may not operate properly. This could ad-
versely affect vehicle handling perfor-
mance, and the

indicator light may

flash or both the

and

indicator

lights may illuminate.

The chassis control is an electric control mod-
ule that includes the following functions:
• Active Trace Control
• Active Engine Brake
• Active Ride Control

ACTIVE TRACE CONTROL

This system senses driving based on the driv-
er’s steering and acceleration/braking pat-
terns, and controls brake pressure at indi-
vidual

wheels

to

help

smooth

vehicle

response.

When the lower display is used to turn off the
Vehicle Dynamic Control system, the Active
Trace Control system is also turned off.

The Active Trace Control can be set to on
(enabled) or off (disabled) through the lower
display “Drive Mode Selector” menu option.
