corrosive materials, check lubrication frequently.
Lights*Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*Tires should be rotated every
7,500 miles (12,000 km) .
Tire, wheel alignment and balanceIf the
vehicle should pull to either side while driving on
a straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
cFor additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet .
Tires*Check the pressure with a gauge at least
once a month and always prior to long distancetrips. If necessary, adjust the pressure in all tires,
including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
WindshieldClean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
Windshield wiper blades*Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the ve-
hicle, etc.
Additional information on the following
items with an “*” is found later in this sec-
tion.
Accelerator pedalCheck the pedal for smooth
operation and make sure the pedal does not bind
or require uneven effort. Keep the floor mat away
from the pedal.
Automatic transmission P (Park) position
mechanismOn a fairly steep hill check that your
vehicle is held securely with the selector lever in
the P position without applying any brakes.Brake pedal and booster*Check the pedal for
smooth operation and make sure it has the proper
distance under it when depressed fully. Check
the brake booster function. Be certain to keep the
floor mat away from the pedal.
BrakesCheck that the brakes do not pull the
vehicle to one side when applied.
Clutch pedal*Make sure the pedal operates
smoothly and check that it has the proper free
travel.
Parking brake*Check that the lever has the
proper travel and confirm that your vehicle is held
securely on a fairly steep hill with only the parking
brake applied.
SeatsCheck seat position controls such as seat
adjusters, seatback recliner, etc. to ensure they
operate smoothly and all latches lock securely in
every position. Check that the head restraints
move up and down smoothly and the locks (if so
equipped) hold securely in all latched positions.

HEADLIGHTS
Replacing the xenon headlight bulb
WARNING
cHIGH 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 head-
lights replaced at a NISSAN dealer. For
additional information, see “Headlight
and turn signal switch” in the “Instru-
ments and controls” section.
Replacing the halogen headlight bulb
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. Be-
cause the headlight assembly must be removed
from the vehicle for bulb replacement, see your
NISSAN dealer.
CAUTION
cAiming is not necessary after replacing
the bulb. When aiming adjustment is
necessary, contact a NISSAN dealer.cDo not leave the headlight assembly
open without a bulb installed for a long
period of time. Dust, moisture, smoke,
etc. entering the headlight body may
affect bulb performance. Remove the
bulb from the headlight assembly just
before a replacement bulb is installed.
cOnly touch the plastic base when han-
dling the bulb. Never touch the glass
envelope. Touching the glass could sig-
nificantly affect bulb life and/or head-
light performance.
cHigh pressure halogen gas is sealed
inside the halogen bulb. The bulb may
break if the glass envelope is scratched
or the bulb is dropped.
cUse the same number and wattage as
originally installed:
Low beam:
Wattage: 55
Bulb no.: H1*
High beam:
Wattage: 60
Bulb no.: HB3 (9005)*
