1. Visually inspect each belt for signs ofunusual wear, cuts, fraying or looseness.
If the belt is in poor condition or loose,
have it replaced or adjusted by an INFINITI
retailer.
2. Have the belts checked regularly for con- dition and tension in accordance with the
maintenance schedule in your “INFINITI
Service and Maintenance Guide”.WARNING
Be sure the engine and the 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 damage
the spark plugs.
REPLACING SPARK PLUGS
If replacement is required, see an INFINITI re-
tailer for servicing.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much
longer. Follow the maintenance schedule in
“INFINITI Service and Maintenance Guide”, but
do not reuse them by cleaning or regapping.
Always replace spark plugs with recommended
or equivalent ones.

out the filter element
2.
The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See “INFINITI Service and Main-
tenance Guide” for maintenance intervals. When replacing the filter, wipe the inside of the
air cleaner housing and the cover with a damp
cloth.
WARNING
●
Operating the engine with the air cleaner
removed can cause you or others to be
burned. The air cleaner not only cleans the
air, it stops flame if the engine backfires. If it
isn’t there, and the engine backfires, you
could be burned. Do not drive with the air
cleaner removed, and be careful when work-
ing on the engine with the air cleaner
removed.
● Never pour fuel into the throttle body or at-
tempt to start the engine with the air cleaner
removed. Doing so could result in serious
injury.
CLEANING
If your windshield is not clear after using the
windshield 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 with a
washer solution or a mild detergent. Your wind-
shield is clean if beads do not form when
rinsing with clear water.
Clean each blade by wiping it with a cloth
soaked in a washer solution or a mild deter-
gent. Then rinse the blade with clear water. If
your windshield is still not clear after cleaning
the blades and using the wiper, replace the
blades.
Worn windshield wiper blades can damage the
windshield and impair driver vision.

Contact an INFINITI retailer if checking or re-
placement is required.If the brakes do not operate properly, have the
brakes checked by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not return
to normal.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear warn-
ings. When a brake pad requires replacement, it
will make a high pitched scraping sound when
the vehicle is in motion. This scraping sound
will first occur only when the brake pedal is
depressed. After more wear of the brake pad,
the sound will always be heard even if the brake
pedal is not depressed. Have the brakes
checked as soon as possible if the wear warn-
ing sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light tomoderate stops is normal and does not affect
the function or performance of the brake sys-
tem.
Proper brake inspection intervals should be fol-
lowed.
For additional information, see the main-
tenance log section of your “INFINITI Service
and Maintenance Guide” for maintenance inter-
vals.

HEADLIGHTS
Replacing
Fog may temporarily form inside the lens of the
exterior lights in the rain or in a car wash. A
temperature difference between the inside and
the outside of the lens causes the fog. This is
not a malfunction. If large drops of water collect
inside the lens, contact an INFINITI retailer.
Xenon headlight bulb (if so equipped) :
If replacement is required, see an INFINITI re-
tailer.
WARNING
HIGH VOLTAGE
When xenon headlights are on, they produce a
high voltage. To prevent an electric shock,
never attempt to modify or disassemble. Al-
ways have your xenon headlights replaced at
an INFINITI retailer. For additional information,
see “HEADLIGHT AND TURN SIGNAL SWITCH” in
the “2. Instruments and controls” section.

If you have a flat tire, see “FLAT TIRE” in the “6. In
case of emergency” section.
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, 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 warn-
ing light” in the “2. Instruments and controls”
section, “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “5. Starting and driving” section
and “TIRE PRESSURE MONITORING SYSTEM
(TPMS)” in the “6. In case of emergency” sec-
tion.
Tire inflation pressure
Check the pressure of the tires (includ-
ing the spare) often and always prior to
long distance trips. The recommendedtire pressure specifications are shown
on the Tire and Loading Information
label under the “Cold Tire Pressure”
heading. The Tire and Loading Informa-
tion 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 mod-
erate speeds.
Incorrect tire pressure, including under
inflation, may adversely affect tire life
and vehicle handling.

WARNING
●Improperly inflated tires can fail sud-
denly and cause an accident.
●The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S.S./
C.M.V.S.S. certification label. The ve-
hicle weight capacity is indicated on
the Tire and Loading Information la-
bel. Do not load your vehicle beyond
this capacity. Overloading your ve-
hicle may result in reduced tire life,
unsafe operating conditions due to
premature tire failure, or unfavorable
handling characteristics and could
also lead to a serious accident. Load-
ing beyond the specified capacity
may also result in failure of other ve-
hicle components.
●Before taking a long trip, or whenever
you heavily load your vehicle, use a
tire pressure gauge to ensure that the
tire pressures are at the specified
level.
●For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.

5Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
6Term of “tubeless” or “tube type”
Indicates whether the tire requires an
inner tube (“tube type”) or not
(“tubeless”).
7The word “radial”
The word “radial” is shown, if the tire
has radial structure.
8Manufacturer or brand name
Manufacturer or brand name is
shown.
Other tire-related terminology:
In addition to the many terms that are
defined throughout this section, In-
tended Outboard Sidewall is (1) the side-
wall that contains a whitewall, bears white lettering or bears manufacturer,
brand and/or model name molding that
is higher or deeper than the same mold-
ing 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 (Example:
Summer, All Season or Snow) and construc-
tion. 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 ve-
hicle 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 Information” (Canada) in
the Warranty Information Booklet.
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 (Mud and Snow) on the tire side-
wall. 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 tires or ALL SEASON tires on all four
wheels.

CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the tires
every 7,500 miles (12,000 km). (See
“FLAT TIRE” in the “6. In case of emer-
gency” section for tire replacing proce-
dures.)
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 tightened to
the specification at all times. It is recom-
mended that wheel nuts be tightened to
the specification at each tire rotation in-
terval.
WARNING
●After rotating the tires, check and ad-
just the tire pressure.
●Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
●Do not include the T-type spare tire or
any other small size spare tire in the
tire rotation.
●For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet. 1. Wear indicator

Tire wear and damage
WARNING
●Tires should be periodically in-
spected for wear, cracking, bulging or
objects caught in the tread. If exces-
sive wear, cracks, bulging or deep
cuts are found, the tire(s) should be
replaced.
