Do-it-yourself

the tire chain must be secured or removed to
prevent the possibility of whipping action
damage to the fenders or underbody. If
possible, avoid fully loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely affected.

Tire chains must be installed only on the
rear wheels and not on the front wheels.

Never install tire chains on a TEMPORARY
USE ONLY spare tire (if so equipped). Never
install tire chains on a punctured run-flat tire
(if so equipped), as this could damage your
vehicle.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.

CHANGING WHEELS AND TIRES

Tire rotation (models equipped with
same size tires on all wheels)

INFINITI recommends rotating the
tires at the specified interval shown
in the maintenance schedule. (See the
“9. Maintenance and schedules” sec-
tion. For tire replacing procedure, see
“Jacking up the vehicle and replacing
tires” (P.8-37).)

As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

Wheel nut tightening torque:

80 ft-lb (108 N·m)

The wheel nuts must be kept tigh-
tened to the specification at all times.
It is recommended that wheel nuts be
tightened to the specification at each
tire rotation interval.

WARNING

.

After rotating the tires, check
and adjust the tire pressure.

.

Do not include the T-type spare
tire or any other small size
spare tire in the tire rotation.

.

For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

After the ignition switch is placed in
the ON position, it may take a period
of time for the tire pressure to be
displayed in the vehicle information

display while the vehicle is driven.
Depending on the radio wave circum-
stance, tire pressure may not cor-
rectly be displayed.

Tire rotation (models equipped with
different size tires on front and rear)

Tires cannot be rotated on this vehi-
cle, as front tires are a different size
from rear tires.
A pin is on the front brake rotor to
prevent the rear wheels from being
installed in place of the front wheels.
The spare tire can be installed in place
of the front and rear wheels. When
installing the spare tire in the front
wheel, the hole in the spare tire wheel
must be aligned with the pin on the
brake rotor.

WARNING

.

If your vehicle is equipped with
different size front and rear
tires, never install the rear
tire/wheel on the front of the
vehicle. Doing so can damage

the vehicle or tire. Damage to
the tire may result in a sudden
loss of air pressure which may
cause loss of vehicle control in
some driving conditions and
cause a collision and personal
injury.

.

For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

Tire wear and damage

WARNING

.

Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced.

Do-it-yourself

8-35

8-36

Do-it-yourself

.

The original tires have built-in
tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.

.

Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.

.

Improper service of the spare
tire may result in serious perso-
nal injury. If it is necessary to
repair the spare tire, it is re-
c o m m e n d e d y o u v i s i t a n
INFINITI retailer for this ser-
vice.

.

For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

Replacing wheels and tires

When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. (See “Speci-
fications” (P.10-8) for recommended types
and sizes of tires and wheels.)
After the ignition switch is placed in the ON
position, it may take a period of time for the
tire pressure to be displayed in the vehicle
information display while the vehicle is
driven. Depending on the radio wave circum-
stance, tire pressure may not correctly be
displayed.

WARNING

.

The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted, radial or run-
flat), or tread patterns can adversely
affect the ride, braking, handling,
ground clearance, body-to-tire clear-
ance, tire chain clearance, speed-
ometer calibration, headlight aim
and bumper height. Some of these
effects may lead to accidents and
could result in serious personal injury.

.

For Two-Wheel Drive (2WD) models,
if your vehicle was originally

equipped with 4 tires that were the
same size and you are only replacing
2 of the 4 tires, install the new tires
on the rear axle. Placing new tires on
the front axle may cause loss of
vehicle control in some driving condi-
tions and cause an accident and
personal injury.

.

If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. See “Wheels and tires” (P.10-
9) of this manual for wheel off-set
dimensions.

.

Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.

.

Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.

.

The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.

.

When replacing the TPMS sensor, the
ID registration may be required. It is
r e c o m m e n d e d y o u c o n t a c t a n
INFINITI retailer for ID registration.

.

Do not use a valve stem cap that is
not specified by INFINITI. The valve
stem cap may become stuck.

.

Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of pres-
sure.

.

Do not install a damaged or deformed
wheel or tire even if it has been
repaired. Such wheels or tires could
have structural damage and could fail
without warning.

.

The use of retread tire is not recom-
mended.

.

For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety
Information” (Canada) in the War-

ranty Information Booklet.

Intelligent All-Wheel Drive (AWD)
models

CAUTION

.

Always use tires of the same type,
size, brand, construction (bias, bias-
belted or radial), and tread pattern
on all four wheels. Failure to do so
may result in a circumference differ-
ence between tires on the front and
rear axles which will cause excessive
tire wear and may damage the trans-
mission, transfer case and differential
gears.

.

ONLY use spare tires specified for
the Intelligent AWD model.

If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
you visit an INFINITI retailer for this service.

Wheel balance

Unbalanced wheels may affect vehicle hand-
ling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.

Wheel balance service should be performed
with the wheels off the vehicle. Spin
balancing the wheels on the vehicle could
lead to mechanical damage.

For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.

comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.

Windshield wiper and washer*:

Check that

the wipers and washer operate properly and
that the wipers do not streak.

Under the hood and vehicle

The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).

Battery*:

Check the fluid level in each cell. It

should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe condition require frequent
checks of the battery fluid level.

NOTE:

Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:

1.

Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)

2.

Vehicle is not driven regularly and/or
only driven short distances.

In these cases, the battery may need to be
charged to maintain battery health.

Brake fluid level*:

Make sure that the brake

fluid level is between the MAX and MIN lines
on the reservoir.

Engine coolant level*:

Check the coolant

level when the engine is cold.

Intercooler coolant level*:

Check the coolant

level when the engine is cold.

Engine drive belts*:

Make sure that no belt is

frayed, worn, cracked or oily.

Make sure there are no

loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting and

driving” (P.5-4).)

Fluid leaks:

Check under the vehicle for fuel,

oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.

Radiator and hoses:

Check the front of the

radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.

Underbody:

The underbody is frequently

exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).

Windshield washer fluid*:

Check that there

is adequate fluid in the reservoir.

The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should

OIL CONTROL SYSTEM

Your vehicle is equipped with oil control
system. It calculates engine oil and filter
change interval based on driving conditions.
Driving in severe conditions will shorten the
engine oil and filter change interval. When
the oil replacement indicator appears in the
vehicle information display, the engine oil
and filter need to be replaced.
