CAUTION
.
Do not ground accessories directly to the
battery terminal. Doing so will bypass
the variable voltage control system and
the vehicle battery may not charge
completely.
.
Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.

The engine could rotate unexpectedly.
1. Visually inspect each belt for signs of
unusual wear, cuts, fraying or loosen-
ess. If the belt is in poor condition or
loose, have it replaced or adjusted. It is
recommended you visit an INFINITI
retailer for this service.
2. Have the belts checked regularly for
condition and tension in accordance
with the maintenance schedule shown
in the “9. Maintenance and schedules”
section of this Owner’s Manual.

REPLACING SPARK PLUGS
If replacement is required, it is recom-
mended 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 main-
tenance schedule shown in the “9. Main-
tenance and schedules” section of this
Owner’s manual, but do not reuse them by
cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.

.
The filter element should not be cleaned
and reused. Replace it according to the
maintenance intervals. See “9. Mainte-
nance and schedules” section of this
Owner’s Manual 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 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
material may be on the blade or wind-
shield.
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.
SDI2359
REPLACING
Replace the wiper blades if they are worn.
1. Pull the wiper arm.
2. Push the release tab
*
A
, 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, return
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 da-
maged from wind pressure.

If you wax the surface of the hood, be
careful not to let wax get into the washer
nozzle
*
A
. This may cause clogging or
improper windshield washer operation. If
wax gets into the nozzle, remove it with a
needle or small pin
*
B
. Be careful not to
damage the nozzle.
It is recommended you contact an INFINITI
retailer if checking or replacement is
required.
If the brakes do not operate properly, it is
recommended you have the brakes
checked by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing 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
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 warning sound is heard.

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,
it is recommended you visit an INFINITI
retailer for servicing.
Xenon headlight bulb (if so equipped):
If replacement is required, it is recom-
mended you visit an INFINITI retailer for
this service.
WARNING
HIGH VOLTAGE
When xenon headlights are on, they pro-
duce a high voltage. To prevent an electric
shock, never attempt to modify or disas-
semble. Always have your xenon headlights
replaced by a certified service technician.
For additional information, see “Headlight
and turn signal switch” (P.2-34).
Halogen headlight bulb (if so equipped):
The headlight is a semi-sealed beam type
which uses a replaceable headlight (halo-
gen) bulb. If replacement is required, it is
recommended you visit an INFINITI retailer
for this service.
CAUTION
.
High pressure halogen gas is sealed
inside the bulb. The bulb may break if
the glass envelope is scratched or the
bulb is dropped.
.
Only touch the plastic base when hand-
ling the bulb. Never touch the glass
envelope. Touching the glass could sig-
nificantly affect bulb life and/or head-
light performance.
.
Do not leave the bulb out of the head-
light reflector for a long period of time as
dust, moisture, and smoke may enter the
headlight body and affect the perfor-
mance of the headlight.
.
Aiming is not necessary after replacing
the bulb. When aiming adjustment is
necessary, it is recommended you visit
an INFINITI retailer for this service.

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 CHECK TIRE
PRESSURE warning appears on the vehicle
information 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.2-14), “Tire Pressure
Monitoring System (TPMS)” (P.5-4) and
“Tire Pressure Monitoring System (TPMS)
” (P.6-3).
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 rat-
ing (GVWR) is located on the F.
M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight
capacity is indicated on the
Tire and Loading Information
label. Do not load your vehicle
beyond this capacity. Over-
loading your vehicle may re-
sult in reduced tire life, unsafe
operating conditions due to
premature tire failure, or un-
favorable handling character-
istics and could also lead to a
serious accident. Loading be-
yond 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 pres-
sure gauge to ensure that the
tire pressures are at the spe-
cified level.
.
For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the War-
ranty Information Booklet.
