Replace the spark plugs according to the main-
tenance schedule shown in a separate mainte-
nance booklet.
If replacement is required, it is recommended
that you visit an INFINITI retailer.
Always replace spark plugs with recommended
or equivalent ones.
WARNING
Be sure the engine and ignition switch are off
and that the parking brake is engaged
securely.
CAUTION
•Be sure to use the correct socket to remove
the spark plugs. An incorrect socket can
cause damage to the spark plugs.It is recommended that you visit an INFINITI
retailer if checking or replacement is required.
WARNING
•Operating the engine with the air cleaner
filter off can cause you or others to be
burned. The air cleaner filter not only cleans
the intake air, it also stops the flame if the
engine backfires. If the air cleaner is not
installed and the engine backfires, you
could be burned. Never drive with the air
cleaner filter off. Be cautious working on the
engine when the air cleaner is off.
•Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result in
serious injury.
CLEANING
If the windshield or rear window is not clear
after using the window washer or if a wiper
blade chatters when running, wax or other
material may be on the blade or windshield.
Clean the outside of the windshield or rear
window with a washer solution or a mild deter-
gent. The windshield or rear window is clean if
beads do not form when rinsing with clear
water.
Clean the blade by wiping it with a cloth soaked
in a washer solution or a mild detergent. Then
rinse the blade with clear water. If the wind-
shield or rear window is still not clear after
cleaning the blades and using the wiper, re-
place the blades.
CAUTION
Worn windshield wiper blades can damage the
windshield and impair driver vision.

SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
brakes. The disc-type brakes self-adjust every
time the brake pedal is applied.Blown fuses must be replaced with fuses of the
same rating, which you can recognise by the
color and fuse rating. The fuse ratings are listed
in the fuse allocation chart.
If the newly inserted fuse also blows, have the
cause traced and rectified. It is recommended
you visit an INFINITI retailer for this service.
The fuses in your vehicle disconnect faulty
circuits. if a fuse blows, all the components on
the circuit and their functions will fail.
BEFORE REPLACING A FUSE
•Secure the vehicle against rolling away.
•Switch off all electrical consumers.
•Remove the key from the ignition lock.
The fuses are located in various fuse boxes:
•Fusebox in the engine compartment on the
left-hand side of the vehicle, when viewed in
the direction of travel.
•Fuse box in the front-passenger footwell.
The fuse allocation chart is on the fuse box in
the front-passenger footwell.

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the low
tire pressure warning light is lit, one or more of
the 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 additional information, refer to Tire Pres-
sure Monitoring System (TPMS) in the
5. Starting and driving section.
Tire inflation pressure
Check the tire pressures (including the spare)
often and always prior to long distance trips.
The recommended tire pressure specifications
are shown on the F.M.V.S.S./C.M.V.S.S. label or
the Tire and Loading Information label (if so
equipped) under the Cold Tire Pressure head-
ing. The Tire and Loading Information label is
affixed to the driver side center pillar. Tire pressures should be checked regularly be-
cause:
•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.
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. certi-
fication label. The vehicle weight capacity is
indicated on the Tire and Loading Informa-
tion label (if so equipped). Do not load your
vehicle beyond this capacity. Overloading
your vehicle may result in reduced tire life,
unsafe operating conditions due to prema-
ture tire failure, or unfavorable handling
characteristics and could also lead to a se-
rious accident. Loading beyond the speci-
fied capacity may also result in failure of
other vehicle components.
WHEELS AND TIRES

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 sidewall 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 (i.e, sum-
mer, 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
they may not match the potential maximum
vehicle speed. Never exceed the maximum
speed rating of the tire.
•Always use tires of the same type, size,
brand, construction and tread pattern on allfour wheels. Failure to do so may result in a
circumference difference between tires on
the front and rear axles which can cause the
Vehicle Dynamic Control (VDC) system to
malfunction resulting in personal injury or
death, excessive tire wear and may damage
the transmission, transfer case and differ-
ential gears.
•For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information“ (Canada)
in the Warranty Information Booklet.
CAUTION
ONLY use spare tires specified for the 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 nec-
essary. It is recommended that you visit an
INFINITI retailer for this service.
All season tires
INFINITI specifies all season tires on some
models to provide good performance all year,
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 models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced 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 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 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.
8-30Do-it-yourself
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
installing studded tires. Skid and traction capa-
bilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
Four-Wheel Drive (4WD) models
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 nec-
essary. It is recommended that you visit an
INFINITI retailer.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed on
235/45 R19 or 235/50 R18 size tires. Installa-
tion of the tire chains/cables on 235/45 R19 or
235/50 R18 size tires will cause damage to the
vehicle. If you plan to use tire chains/cables,
you should install 215/60 R17 size tires on your
vehicle.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 that they are of proper size for the
tires on your vehicle and are installed according
to the chain manufacturer’s instructions.
Use chain tensioners when recommended by
the tire chain manufacturer to ensure a tight fit.
Loose end links of the tire chains must be
secured or removed to prevent the possibility of
whipping action damage to the fenders or un-
derbody. If possible, avoid fully loading your
vehicle when using tire chains. In addition,
drive at a reduced speed. Otherwise, your ve-
hicle may be damaged and/or vehicle handling
and performance may be adversely affected.
Tire chains must be installed only on the front
wheels and not on the rear wheels.
Never install tire chains on a T-type spare tire
(TEMPORARY USE ONLY).
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains in
such conditions can cause damage to the vari-
ous mechanisms of the vehicle due to some
overstress.

TIRE WEAR AND DAMAGE
WARNING
•Tires should be periodically inspected for
wear, cracking, bulging or objects caught in
the tread. If excessive wear, cracks, bulging
or deep cuts are found, the tire should be
replaced immediately.
•The original tires have a built-in tread wear
indicator. When the wear indicator is vis-
ible, the tire should be replaced.
•Tires degrade with age and use. Have tires,
including the spare, over 6 years old
checked by a qualified technician because
SDI1663Z
Do-it-yourself8-31
some tire damage may not be obvious. Re-
place 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, it is recommended
that you visit an INFINITI retailer for this
service.
•For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the Warranty Information Booklet.
Tires should be periodically inspected for wear,
cracking, bulging or objects caught in the tread.
If excessive wear, cracks, bulging or deep cuts
are found, the tire should be replaced immedi-
ately.
The original tires have a built-in tread wear
indicator. When the wear indicator is visible,
the tire should be replaced.
Improper servicing of a tire may result in seri-
ous personal injury. If it is necessary to repair a
tire, it is recommended you contact an INFINITI
retailer.
TIRE ROTATION
INFINITI recommends rotating the tires every
5,000 miles (8,000 km).
For additional information on tire replacing
procedures, refer to Flat tirein the6. In case
of emergency section.As soon as possible,
tighten the wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque: 96 ft-lb (130 N·m)
The wheel nuts must be kept tightened to speci-
fications at all times. It is recommended that
wheel nuts be tightened to specification at each
tire rotation interval.
WARNING
•After rotating the tires, check and adjust the
tire pressure.
•Do not include the spare tire in the tire rota-
tion.
•For additional information regarding tires,
refer to Important Tire Safety Information
(US) or Tire Safety Information in the War-
ranty Information Booklet.
REPLACING WHEELS AND TIRES
WARNING
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.
When replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. (See Wheels and Tires in the
9. Maintenance and Schedules section for
recommended types and sizes of tires and
wheels.)
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, possibly
degraded vehicle handling characteristics
and/or interference with the brake discs/
drums. Such interference can lead to decreased
braking efficiency and/or early brake pad/shoe
wear.
8-32Do-it-yourself
Confirm the following for the TPMS:
WARNING
•The use of tires other than those recom-
mended or the mixed use of tires of different
brands, construction (bias, bias-belted or
radial), or tread patterns can adversely af-
fect the ride, braking, handling, VDC sys-
tem, ground clearance, body-to-tire clear-
ance, tire chain clearance, speedometer
calibration, headlight aim and bumper
height. Some of these effects may lead to
accidents and could result in serious per-
sonal injury.
•For 2WD models, if your vehicle was origi-
nally 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
conditions and cause an accident and per-
sonal injury.
•If the wheels are changed for any reason,
always replace with wheels which have the
same off-set dimension. Wheels of a differ-
ent off-set could cause premature tire wear,
degrade vehicle handling characteristics,
affect the VDC system and/or interference
with the brake discs. Such interference canlead to decreased braking efficiency and/or
early brake pad wear. For additional infor-
mation on wheel off-set dimensions, refer to
Wheels and Tires
in the9. Maintenance
and Schedules section.
•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not func-
tion and the low tire pressure warning light
will flash for approximately 1 minute. The
light will remain on after 1 minute. Contact
an 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.
•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 recom-
mended that you visit an INFINITI retailer for
ID registration.
•Do not use a valve stem cap that is not speci-
fied by INFINITI. The valve stem cap may
become stuck.
•Be sure that the valve stem caps are cor-
rectly fitted. Otherwise the valve may be clogged up with dirt and cause a malfunc-
tion or loss of pressure.
•Do not install a damaged or deformed wheel
or tire even if it has been repaired. Such
wheels or tires could have structural dam-
age and could fail without warning.
•The use of retread tires is not recom-
mended.
•For additional information regarding tires,
refer to
Important Tire Safety Information
(US) or Tire Safety Information (Canada) in
the Warranty Information Booklet.
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.
