Wheel nuts*:
When checking the tires, make sure no nuts
are missing, and check for any loose nuts.
Tighten if necessary.
Tire rotation*:
Tires should be rotated every 7,500 miles
(12,000 km). However, the timing for tire rota-
tion may vary according to your driving habits
and road surface conditions.
Wheel alignment and balance:
If 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.
For additional information regarding tires, refer
to ªImportant Tire Safety Informationº in the
Warranty Information Booklet (US) or ªTire
Safety Informationº in the Warranty Informa-
tion booklet (Canada).
Windshield:Clean the windshield on a regu-
lar basis. Check the windshield at least every
six months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.Windshield wiper blades*:
Check for cracks or wear if they do not wipe
properly.
Doors and engine hood:
Check that all doors and the engine hood,
operate properly. Also ensure that all latches
lock securely. Lubricate hinges, latches, rollers
and links if necessary. Make sure that the
secondary latch keeps the hood from opening
when the primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication fre-
quently.
Inside the vehicleLights*:
Clean the headlights on a regular basis. Make
sure that the headlights, stop lights, tail lights,
turn signal lights, and other lights are all oper-
ating properly and installed securely. Also
check headlight aim.INTERIOR MAINTENANCEThe maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.Warning lights and chimes:
Make sure that all warning lights and chimes
are operating properly.
Windshield wiper and washer*:
Check that the wipers and washer operate
properly and that the wipers do not streak.
Windshield defroster:
Check that the air comes out of the defroster
outlets properly and in sufficient quantity when
operating the heater or air conditioner.
Steering wheel:
Check for changes in the steering conditions,
such as excessive freeplay, hard steering or
strange noises.
Seats:
Check seat position controls such as seat
adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints move up and down smoothly and
that the locks (if so equipped) hold securely in
all latched positions.
Seat belts:
Check that all parts of the seat belt system

CHECKING BRAKE PEDALWith the engine running, check distance A
between the upper surface of the pedal and
the dash lower panel.
Distance A
M/T models
2-1/2 in (65 mm) or more
A/T models
2-3/4 in (70 mm) or more
If it is out of the range shown above, see your
NISSAN dealer.
Self-adjusting brakesYour vehicle is equipped with self-adjusting
brakes.
The front and rear brakes self-adjust every
time the brake pedal is applied.
WARNING
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.Brake pad wear indicatorsThe disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it will make a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indi-
cator sound is heard.
Under some driving or climate conditions, oc-
casional 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.The rear drum brakes (if so equipped) do not
have audible wear indicators. Should you ever
hear an unusually loud noise from the rear
drum brakes, have them inspected as soon as
possible by your NISSAN dealer.
Proper brake inspection intervals should
be followed.For additional information, see
ªPeriodic maintenanceº shown in a separate
maintenance booklet for maintenance inter-
vals.
BRAKE BOOSTERCheck the brake booster function with the
following steps:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) re-
mains the same from one pedal application
to the next, continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a
little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height should
not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it off.

Depress the brake pedal several times. The
pedal travel distance will decrease gradu-
ally with each depression as the vacuum is
released from the booster.
If the brakes do not operate properly, have the
brake checked by your NISSAN dealer.
CHECKING CLUTCH PEDALPress the pedal by hand and be sure the free
travel is within the above limit. If free travel is
out of the range shown above, see your
NISSAN dealer.

fuel additives (i.e.: fuel injector cleaner, octane
booster, intake valve deposit removers, etc.)
which are sold commercially. Many of these
additives intended for gum, varnish or deposit
removal may contain active solvents or similar
ingredients that can be harmful to the fuel
system and engine.Octane rating tipsIn most parts of North America, you should use
unleaded gasoline with an octane rating of at
least 91 AKI (Anti-Knock Index) number
(VQ35DE engine) or 87 AKI (Anti-knock Index)
number (VG33E engine). However, you may
use unleaded gasoline with an octane rating
as low as 85 AKI (Anti-Knock Index) number in
these high altitude areas [over 4,000 ft (1,219
m)] such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada, south-
ern Idaho, western South Dakota, western
Nebraska, and that part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knockwhile holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may
cause excessive fuel consumption or damage
to the engine. If any of the above symptoms
are encountered, have your vehicle checked at
a NISSAN dealer or other competent service
facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time.
