REPLACING SPARK PLUGS

If replacement is required, it is recommended
you visit an INFINITI retailer for this service.

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 “9. Maintenance and schedules”
section of this manual, but do not reuse
them by cleaning or regapping.

Always replace spark plugs with recom-
mended or equivalent ones.

Remove the retainers

as illustrated and

pull out the filter element

.

The filter element should not be cleaned and
reused. Replace it according to the main-
tenance schedule shown in the “9. Main-
tenance and schedules” section. When
replacing the filter, wipe the inside of the
air cleaner housing and the cover with a

AIR CLEANER

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 care-
ful when working on the engine with
the air cleaner removed.

. 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 your windshield is not clear after using the
windshield washer or if a wiper blade
chatters when running, wax or other materi-
al may be on the blade or windshield.

Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield 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
detergent. 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.

When a washer nozzle is clogged

If a washer nozzle is clogged or any
malfunction occurs, have it checked. It is
recommended you visit an INFINITI retailer
for this service. Do not attempt to clean the
nozzle using a needle or a pin. Doing so may
damage the nozzle.

REPLACING

Replace the wiper blades if they are worn.

Before replacing the wiper blades, the wiper
should be in the fully up position to avoid
scratching the engine hood or damaging the
wiper arm. To pull up the wiper arm, see
“Wiper and washer switch” (P.2-34).

1. Pull the wiper arm.

2. Push the release tab

, and then move

the wiper blade down the wiper arm
while pushing the release tab to remove.

3. Insert the new wiper blade onto the

wiper arm until a click sounds.

4. Rotate the wiper blade so the dimple is in

the groove.

CAUTION

. After wiper blade replacement, re-

turn the wiper arm to its original
position;

otherwise it may be damaged when
the hood is opened.

. Make sure the wiper blades contact

the glass; otherwise the arm may be
damaged from wind pressure.

If the brakes do not operate properly, have
the brakes checked. It is recommended you
visit an INFINITI retailer for this service.

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

Have your brake system checked if the
brake pedal height does not return to
normal. It is recommended you visit an
INFINITI retailer for this service.

BRAKE PAD WEAR WARNING

The disc brake pads have audible wear
warnings. When a brake pad requires repla-
cement, 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 warning sound is
heard.

BRAKES

Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake noise
during light to moderate stops is normal and
does not affect the function or performance
of the brake system.

Proper brake inspection intervals should be
followed. For additional information, see the
maintenance schedule shown in the “9.
Maintenance and schedules” section.

tended storage fuse switch comes from the
factory switched off. Prior to delivery of
your vehicle, the switch is pushed in
(switched on) and should always remain on.

If the extended storage fuse switch is not
pushed in (switched on), the “Shipping Mode

If the extended storage fuse switch mal-
functions or if the fuse is open, it is not
necessary to replace the switch. In this case,
remove the extended storage fuse switch
and replace it with a new fuse of the same
rating.

To replace the battery:

1. Release the lock knob at the back of the

Intelligent Key and remove the mechan-
ical key.

If you have a flat tire, see “Flat tire” (P.6-3).

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 “Tire Pressure Low - Add
Air” warning appears in the vehicle informa-
tion 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 Mon-
itoring System (TPMS)” (P.5-5) and “Tire
Pressure Monitoring System (TPMS)” (P.6-
3).

Tire inflation pressure
Check the pressure of the tires (in-
cluding the spare) often and always
prior to long distance trips. The
recommended tire pressure specifica-
tions 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 ob-
jects 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.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. (See “TPMS with Tire Infla-
tion Indicator” (P.5-8) about the
TPMS with Tire Inflation Indicator.)
Incorrect tire pressure, including un-
der inflation, may adversely affect

tire life and vehicle handling.

WARNING

. Improperly inflated tires can fail

suddenly and cause an accident.

. The Gross Vehicle Weight rat-

ing (GVWR) is located on the F.
M.V.S.S./C.M.V.S.S. label. The
vehicle weight capacity is indi-
cated on the Tire and Loading
Information label. Do not load
your vehicle beyond this capa-
city. Overloading your vehicle
may result in reduced tire life,
unsafe operating conditions
due to premature tire failure,
or unfavorable handling char-
acteristics 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

WHEELS AND TIRES

pressures are at the specified
level.

. 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 and Loading Information label

Seating capacity: The maximum
number of occupants that can be
seated in the vehicle.
Vehicle load limit: See “Vehicle
loading information” (P.10-15).

Original size: The size of the tires
originally installed on the vehicle
at the factory.
Cold tire pressure: Inflate the
tires to this pressure when the
tires are cold. Tires are consid-

ered COLD after the vehicle has
been parked for 3 or more hours,
or driven less than 1 mile (1.6 km)
at moderate speeds. The recom-
mended cold tire inflation is set
by the manufacturer to provide
the best balance of tire wear,
vehicle handling, driveability, tire
noise, etc., up to the vehicle’s
GVWR.
