When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to yourself
or damage to the vehicle. The following are
general precautions which should be closely
observed.
WARNINGO Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral) position. For an automatic
transmission, move the selector lever
to P (Park) position.
O Be sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
O If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
O It is advised to secure or remove any loose clothing and any jewelry, such
as rings, watches, etc. before work-
ing on your vehicle.
O Always wear eye protection when-
ever you work on your vehicle.
O If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
O Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
O Keep smoking materials, flame and
sparks away from fuel and the bat-
tery.
O On gasoline engine models with the
Multiport Fuel Injection (MFI) System,
the fuel filter or fuel lines should be
serviced by an INFINITI retailer be-
cause the fuel lines are under high
pressure even when the engine is off. CAUTION O Do not work under the hood while the
engine is hot. Turn off the engine and
wait until it cools down.
O Never connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
O Never leave any engine or automatic
transmission related component har-
ness connector disconnected while
the ignition key is on.
O Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.

If you have a flat tire, see ªFlat tireº in the
ª6. In case of emergencyº section.
TIRE PRESSURE
Maximum inflation pressure Do not exceed the maximum inflation pres-
sures shown on the side wall of the tire.
Tire inflation pressure Check the tire pressure (including spare) at
least once a month and always prior to long
distance trips. Incorrect tire pressure may ad-
versely affect tire life and vehicle handling. Tire
pressure should be checked when tires are
COLD. 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. COLD tire pressures are shown on
the tire placard affixed to the inside of the rear
left door opening (Sedan), the driver side
center pillar (Coupe).
WARNING O Improperly inflated tires can fail sud-
denly and cause an accident.
O The vehicle capacity weight is indi-
cated on the tire placard. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may result
in reduced tire life, unsafe operating
conditions due to premature tire fail-
ure, or unfavorable handling charac-
teristics and could also lead to a
serious accident. Loading beyond the
specified capacity may also result in
failure of other vehicle components.
O Before taking a long trip, or whenever
you have loaded your vehicle heavily,
use a tire pressure gauge to ensure
that the tire pressure is at the speci- fied level.
O Do not drive your vehicle over 85
MPH (140 km/h) unless it is equipped
with high speed capability tires. Driv-
ing faster than 85 MPH (140 km/h)
may result in tire failure, loss of con-
trol and possible injury.
O For additional information regarding
tires, refer to ªImportant Tire Safety
Informationº (US) or ªTire Safety In-
formationº (Canada) in the INFINITI
Warranty Information Booklet.
TYPES OF TIRES
WARNING When changing or replacing tires, be
sure all four tires are of the same type
(i.e., summer, all season or snow) and
construction. Your 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 factoryDI1033M

equipped tires, and may not match the
potential maximum vehicle speed. Never
exceed the maximum speed rating of the
tire.
For additional information regarding
tires, refer to ªImportant Tire Safety In-
formationº (US) or ªTire Safety Informa-
tionº (Canada) in the INFINITI Warranty
Information Booklet.
All season tires INFINITI specifies all season tires on some
models to provide good performance for use
all year around, including snowy and icy road
conditions. All season tires are identified by
ALL SEASON and/or M&S 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 mod-
els to provide superior performance on dry
roads. Summer tire performance in snow and
ice will be substantially reduced. Summer tires
do not have the tire traction rating M&S on the
tire sidewall. If you operate your vehicle in snowy or icy
conditions, INFINITI recommends the use of
snow 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 operate your vehicle in snowy or icy
conditions, INFINITI recommends the use of
snow or all season tires on all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some provinces
and states prohibit 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 install-
ing tire chains. When installing tire chains,
make sure they are of proper size for the tires
on your vehicle and are installed according to
the chain manufacturer's suggestions. Use
only SAE class S chains. Class ªSº chains
are used on vehicles with restricted tire to
vehicle clearance. Vehicles that can use Class
ªSº chains are designed to meet the SAE
standard minimum clearances between the
tire and the closest vehicle suspension or body
component required to accommodate the use
of a winter traction device (tire chains or
cables). The minimum clearances are deter-
mined using the factory equipped tire size.
Other types may damage your vehicle. Use
chain tensioners when recommended 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
undercarriage. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise, your
vehicle may be damaged and/or vehicle han-
dling and performance may be adversely af-
fected.
Never install tire chains on a T-type spare
tire. Do not use the chains on dry roads. Do-it-yourself

CHANGING WHEELS AND TIRES
Tire rotation (Sedan) INFINITI recommends that tires be rotated
every 7,500 miles (12,000 km).
Wheel nut tightening torque:
80 ft-lb (108 N z m)
See ªFlat tireº in the ª6. In case of emergencyº
section for tire replacing procedures.
Tire rotation (Coupe) Tires cannot be rotated in this vehicle, as front
tires are different size from rear tires and the
direction of wheel rotation is fixed in each tire. 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 O After rotating the tires, adjust the tire
pressure.
O Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
O Do not include the T-type spare tire or
any other small size spare tire in the
tire rotation.
O For additional information regarding
tires, refer to ªImportant Tire Safety-
Informationº (US) or ªTire Safety In-
formationº (Canada) in the INFINITI
Warranty Information Booklet. Tire wear and damage
WARNING O Tires should be periodically in-
spected for wear, cracking, bulging,
or objects caught in the tread. If ex-
cessive wear, cracks, bulging, or
deep cuts are found, the tire should
be replaced.
O The original tires have a built-in tread
wear indicator. When the wear indica-DI0048-C MDI0004

Z 02.11.1/V35-D/V5.0
X

tor is visible, the tire should be re-
placed.
O Improper service for a spare tire may
result in serious personal injury. If it
is necessary to repair the spare tire,
contact your INFINITI retailer.
O For additional information regarding
tires, refer to ªImportant Tire Safety
Informationº (US) or ªTire Safety In-
formationº (Canada) in the INFINITI
Warranty Information Booklet.
Replacing wheels and tires When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. See ªSpecificationsº in the
ª10. Technical and consumer informationº sec-
tion for recommended types and sizes of tires
and wheels.
WARNINGO 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, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.
O If the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, possibly
degraded vehicle handling character-
istics and/or interference with the
brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear.
O Do not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without
warning. O The use of retread tires is not recom-
mended.
O For additional information regarding
tires, refer to ªImportant Tire Safety
Informationº (US) or ªTire Safety In-
formationº (Canada) in the INFINITI
Warranty Information Booklet.
Wheel balance Unbalanced wheels may affect vehicle han-
dling 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 rear wheels on the vehicle could lead to
transmission damage.
For additional information regarding tires, refer
to ªImportant Tire Safety Informationº (US) or
ªTire Safety Informationº (Canada) in the
INFINITI Warranty Information Booklet.
Care of wheels O Wash the wheels when washing the vehicle
to maintain their appearance.
O Clean the inner side of the wheels when the Do-it-yourself
8-33
Z 02.7.29/V35-D/V5.0
X

wheel is changed or the underside of the
vehicle is washed.
O Do not use abrasive cleaners when wash-
ing the wheels.
O Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
O INFINITI recommends that the road wheels
be waxed to protect against road salt in
areas where it is used during winter.
Spare tire (T-type spare tire) Observe the following precautions if the T-type
spare tire must be used, otherwise your ve-
hicle could be damaged or involved in an
accident.
CAUTIONO The T-type spare tire should be used
only for emergency. It should be re-
placed by the standard tire at the first
opportunity.
O Drive carefully while the T-type spare
tire is installed. Avoid sharp turns and abrupt braking
while driving.
O Periodically check the T-type spare
tire inflation pressure, and always
keep it at 60 psi (420 kPa, 4.2 bar).
O Always keep the pressure of the full
size spare tire (if so equipped) at the
recommended pressure for standard
tires, as indicated on the tire placard.
For tire placard location, see ªTire
placardº in the ª10. Technical and
consumer informationº.
O Do not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
O Do not use tire chains on a T-type
spare tire. Tire chains will not fit prop-
erly on the T-type spare tire and may
cause damage to the vehicle.
O When driving on roads covered with
snow or ice, the T-type spare tire
should be used on the front wheel
and the original tire used on the rear
wheels (drive wheels). Use tire chains only on the rear two original tires.
(Sedan)
O Tire tread of the T-type spare tire will
wear at a faster rate than the original
tire. Replace the T-type spare tire as
soon as the tread wear indicators
appear.
O Because the T-type spare tire is
smaller than the original tire, ground
clearance is reduced. To avoid dam-
age to the vehicle do not drive over
obstacles. Also do not drive the ve-
hicle through an automatic car wash
since it may get caught.
O Do not use the T-type spare tire on
other vehicles.
O Do not use more than one T-type
spare tire at the same time.
O Do not tow a trailer while the T-type
spare tire is installed.
