Infiniti G Convertible (2012 year). Manual — part 27

If you have a flat tire, see “Flat tire” (P.6-
2).

TIRE PRESSURE

Tire Pressure Monitoring System
(TPMS)

This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears on the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.

The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not
detect a sudden drop in tire pressure (for
example a flat tire while driving).

For more details, see “Low tire pressure
warning light” (P.2-12), “Tire Pressure
Monitoring System (TPMS)” (P.5-4) and
“Tire Pressure Monitoring System (TPMS)”
(P.6-2).

Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al-

ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure” heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
. Most tires naturally lose air over

time.

. Tires can lose air suddenly when

driven over potholes or other
objects or if the vehicle strikes a
curb while parking.

The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle
has been parked for 3 or more hours,
or driven less than 1 mile (1.6 km) at
moderate speeds.
Incorrect tire pressure, including
under inflation, may adversely affect
tire life and vehicle handling.

WARNING

. Improperly inflated tires can fail

suddenly and cause an accident.

. The Gross Vehicle Weight rating

(GVWR) is located on the F.M.V.S.
S./C.M.V.S.S. label. The vehicle
weight capacity is indicated on
the Tire and Loading Information
label. Do not load your vehicle
beyond this capacity. Overloading
your vehicle may result in reduced
tire life, unsafe operating condi-
tions due to premature tire failure,
or unfavorable handling character-
istics and could also lead to a
serious accident. Loading beyond
the specified capacity may also
result in failure of other vehicle
components.

. Before taking a long trip, or

whenever you heavily load your
vehicle, use a tire pressure gauge
to ensure that the tire pressures

Checking the tire pressure

1. Remove the valve stem cap from

the tire.

2. P r e s s t h e p r e s s u r e g a u g e

squarely onto the valve stem. Do
not press too hard or force the
valve stem sideways, or air will
escape. If the hissing sound of air
escaping from the tire is heard
while checking the pressure, re-
position the gauge to eliminate
this leakage.

3. Remove the gauge.
4. Read the tire pressure on the

gauge stem and compare it to
the specification shown on the
Tire and Loading Information la-
bel.

5. Add air to the tire as needed. If

too much air is added, press the
core of the valve stem briefly with
the tip of the gauge stem to
release pressure. Recheck the
pressure and add or release air
as needed.

6. Install the valve stem cap.
7. Check the pressure of all other

tires, including the spare.

TIRE LABELING

Federal law requires tire manufac-
turers to place standardized informa-
tion on the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.

SDI1606

Example

*

1 Tire size (example: P215/60R16

94H)

1. P: The “P” indicates the tire is

designed for passenger vehicles.
(Not all tires have this informa-
tion.)

2. Three-digit number (215): This

number gives the width in milli-
meters of the tire from sidewall
edge to sidewall edge.

3. Two-digit number (60): This num-

ber, known as the aspect ratio,

gives the tire’s ratio of height to
width.

4. R: The “R” stands for radial.
5. Two-digit number (16): This num-

ber is the wheel or rim diameter in
inches.

6. Two- or three-digit number (94):

This number is the tire’s load
index. It is a measurement of
how much weight each tire can
support. You may not find this
information on all tires because it
is not required by law.

7. H: Tire speed rating. You should

not drive the vehicle faster than
the tire speed rating.

SDI1607

Example

Other tire-related terminology:
In addition to the many terms that
are defined throughout this section,
Intended Outboard Sidewall is (1) the
sidewall that contains a whitewall,

bears white lettering or bears manu-
facturer, brand and/or model name
molding that is higher or deeper than
the same molding on the other side-
wall of the tire, or (2) the outward
facing sidewall of an asymmetrical
tire that has a particular side that
must always face outward when
mounted on a vehicle.

TYPES OF TIRES

WARNING

.

When changing or replacing tires, be
sure all four tires are of the same type
(Example: Summer, All Season or Snow)
and construction. An INFINITI retailer
may be able to help you with information
about tire type, size, speed rating and
availability.

.

Replacement tires may have a lower
speed rating than the factory equipped
tires, and may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.

.

Replacing tires with those not originally

specified by INFINITI could affect the
proper operation of the TPMS.

.

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

All season tires

INFINITI specifies all season tires on some
models to provide good performance all
year, including snowy and icy road condi-
tions. All Season tires are identified by ALL
SEASON and/or M&S (Mud and Snow) on
the tire sidewall. Snow tires have better
snow traction than All Season tires and
may be more appropriate in some areas.

Summer tires

INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating M&S on the tire sidewall.

If you plan to operate your vehicle in snowy
or icy conditions, INFINITI recommends the
use of SNOW tires or ALL SEASON tires on

all four wheels.

Snow tires

If snow tires are needed, it is necessary to
select tires equivalent in size and load
rating to the original equipment tires. If
you do not, it can adversely affect the
safety and handling of your vehicle.

Generally, snow tires will have lower speed
ratings than factory equipped tires and
may not match the potential maximum
vehicle speed. Never exceed the maximum
speed rating of the tire.

If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.

For additional traction on icy roads,
studded tires may be used. However, some
U.S. states and Canadian provinces prohi-
bit their use. Check local, state and
provincial laws before installing studded
tires. Skid and traction capabilities of
studded snow tires, on wet or dry surfaces,
may be poorer than that of non-studded
snow tires.

TIRE CHAINS

Use of tire chains may be prohibited
according to location. Check the local laws
before installing tire chains. When instal-
ling tire chains, make sure they are the
proper size for the tires on your vehicle and
are installed according to the chain man-
ufacturer’s suggestions. Use only SAE
Class S chains. Class “S” chains are used
on vehicles with restricted tire to vehicle
clearance. Vehicles that can use Class “S”
chains are designed to meet the SAE
standard minimum clearances between
the tire and the closest vehicle suspension
or body component required to accommo-
date the use of a winter traction device (tire
chains or cables). The minimum clearances
are determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of 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 af-
fected.

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.

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
Tires cannot be rotated on this
vehicle because the front tires are a
different size than the 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.

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.

. 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 personal
injury. If it is necessary to repair
the spare tire, contact an INFINITI
retailer.

. For additional information regard-

ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) in
the Warranty Information Booklet.

Replacing wheels and tires

When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. (See
“Specifications” (P.9-8) for recommended
types and sizes of tires and wheels.)

WARNING

.

The use of tires other than those
recommended or the mixed use of tires
of different brands, construction (bias,
bias-belted or radial), or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-tire
clearance, 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.

.

If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimension.
Wheels of a different off-set could cause
premature tire wear, degrade vehicle
handling characteristics and/or interfer-
ence with the brake discs/drums. Such
interference can lead to decreased brak-

ing efficiency and/or early brake pad/
shoe wear. See “Wheels and tires” (P.9-
9) of this manual for wheel off-set
dimensions.

.

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.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.

.

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

.

Do not install a damaged or deformed
wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural 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 Infor-
mation” (Canada) in the Warranty Infor-
mation Booklet.

Wheel balance

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

Wheel balance service should be per-
formed 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 Book-
let.

Care of wheels

. Wash the wheels when washing the

vehicle to maintain their appearance.

. Clean the inner side of the wheels when

the wheel is changed or the underside
of the vehicle is washed.

. Do not use abrasive cleaners when

washing the wheels.

. Inspect wheel rims regularly for dents

or corrosion. Such damage may cause
loss of pressure or poor seal at the tire
bead.

Maintenance and do-it-yourself

8-37

8-38

Maintenance and do-it-yourself

. INFINITI recommends that the road

wheels be waxed to protect against
road salt in areas where it is used
during winter.

Spare tire (TEMPORARY USE ONLY
(T-type) spare tire) (if so equipped)

Observe the following precautions if the T-
type spare tire must be used, otherwise
your vehicle could be damaged or involved
in an accident.

WARNING

.

The T-type spare tire should be used for
emergency use. It should be replaced
with the standard tire at the first
opportunity to avoid possible tire or
differential damage.

.

Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.

.

Periodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire at
60 psi (420 kPa, 4.2 bar). Always keep
the pressure of the full size spare tire (if
so equipped) at the recommended pres-

sure for standard tires, as indicated on
the Tire and Loading Information label.
For Tire and Loading Information label
location, see “Tire and Loading Informa-
tion label” in the index of this manual.

.

With the TEMPORARY USE ONLY spare
tire installed do not drive your vehicle at
speeds faster than 50 MPH (80 km/h).

.

When driving on roads covered with
snow or ice, the TEMPORARY USE ONLY
spare tire should be used on the front
wheels and original tire used on the rear
wheels (drive wheels). Use tire chains
only on the two rear original tires.

.

Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than
the standard tire. Replace the spare tire
as soon as the tread wear indicators
appear.

.

Do not use the spare tire on other
vehicles.

.

Do not use more than one spare tire at
the same time.

CAUTION

.

Do not use tire chains on a TEMPORARY
USE ONLY spare tire. Tire chains will not
fit properly and may cause damage to
the vehicle.

.

Because the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also do not drive
the vehicle through an automatic car
wash since it may get caught.

Emergency tire puncture repair kit
(if so equipped)

The emergency tire puncture repair kit
(Emergency Tire Sealant) is supplied with
the vehicle instead of a spare tire. It can be
used to temporarily repair minor tire
punctures.

If possible, have the vehicle towed to a
facility that can repair or replace the flat
tire. Using the emergency tire puncture
repair kit may cause a malfunction of the
tire pressure sensor and cause the low tire
pressure warning light to illuminate.

See “Flat tire” (P.6-2) for more details.

FUEL RECOMMENDATION

VQ37VHR engine

Use unleaded premium gasoline with an
octane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number
96).

If premium gasoline is not available,
unleaded regular gasoline with an octane
rating of 87 AKI number (Research octane
number 91) may be temporarily used, but
only under the following precautions:

. Have the fuel tank filled only partially

with unleaded regular gasoline, and fill
up with unleaded premium gasoline as
soon as possible.

. Avoid full throttle driving and abrupt

acceleration.

However, for maximum vehicle perfor-
mance, the use of unleaded premium
gasoline is recommended.

CAUTION

.

Using a fuel other than that specified
could adversely affect the emission
control system, and may also affect
warranty coverage.

.

Under no circumstances should a leaded
gasoline be used, because this will
damage the three-way catalyst.

.

Do not use E-85 fuel in your vehicle. Your
vehicle is not designed to run on E-85
fuel. Using E-85 fuel can damage the fuel
system components and is not covered
by the INFINITI vehicle limited warranty.

Gasoline specifications

INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter (WWFC)
specifications where it is available. Many
of the automobile manufacturers devel-
oped this specification to improve emis-
sion system and vehicle performance. Ask
your service station manager if the gaso-
line meets the World-Wide Fuel Charter
(WWFC) specifications.

Reformulated gasoline

Some fuel suppliers are now producing
reformulated gasolines. These gasolines
are specially designed to reduce vehicle
emissions. INFINITI supports efforts to-
wards cleaner air and suggests that you
use reformulated gasoline when available.

Gasoline containing oxygenates

Some fuel suppliers sell gasoline contain-
ing oxygenates such as ethanol, MTBE and
methanol with or without advertising their
presence. INFINITI does not recommend the
use of fuels of which the oxygenate content
and the fuel compatibility for your INFINITI
cannot be readily determined. If in doubt,
ask your service station manager.

If you use oxygenate-blend gasoline,
please take the following precautions as
the usage of such fuels may cause vehicle
performance problems and/or fuel system
damage.

. The fuel should be unleaded and have

an octane rating no lower than that
recommended for unleaded gasoline.

. If an oxygenate-blend, excepting a

methanol blend, is used, it should
contain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)

. If a methanol blend is used, it should

contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
