ground or place the vehicle on a flat bed
truck as illustrated.
CAUTION
cNever tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground
(forward or backward), as this may
cause serious and expensive dam-
age to the transmission. If it is nec-
essary to tow the vehicle with the
front wheels raised, always use tow-
ing dollies under the rear wheels.
cWhen towing automatic or manual
transmission models with the front
wheels on the ground or on towing
dollies:
Turn the ignition key to the OFF
position, and secure the steering
wheel in a straight ahead position
with a rope or similar device.
Never secure the steering wheel
by turning the ignition key to the
LOCK position. This may damage
the steering lock mechanism.cIf you have to tow manual transmis-
sion models with the rear wheels on
the ground (if you do not use towing
dollies) or four wheels on the
ground:
cAlways release the parking
brake.
cMove the transmission shift le-
ver to the N (Neutral) position.
cObserve the following re-
stricted towing speeds and dis-
tances for manual transmis-
sion models only:
Speed: Below 60 MPH (97 km/h)
Distance: Less than 500 miles
(805 km)
If the speed or distance must necessarily be
greater, remove the propeller shaft before
towing to prevent damage to the transmis-
sion.
Four-wheel drive models
NISSAN recommends that towing dollies be
used when towing your vehicle or place the
vehicle on a flat bed truck as illustrated.

Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front disc-type brakes self-adjust every
time the brake pedal is applied. The rear
drum-type brakes on two-wheel drive trucks
self-adjust every time the parking brake is
applied. The rear drum-type brakes on four-
wheel drive trucks self-adjust every time the
brake pedal is applied. If the brake pedal
goes down farther than normal, it may be
due to a lack of adjustment of the rear drum
brakes. Apply the parking brake several
times.
WARNING
If the brake pedal height does not re-
turn to normal, see an authorized
NISSAN dealer and have it checked.
Brake pad wear indicators
The 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
indicator sound is heard.
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 nor-
mal 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 an authorized
NISSAN dealer.Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``NISSAN Service and Maintenance Guide.''
BRAKE BOOSTER
Check 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) remains the same from one pedal
application to the next, continue on to
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 de-

TIRE PRESSURE
Maximum inflation pressure
Do not exceed the maximum inflation pres-
sures shown on the side wall of the tire.
Tire inflation pressure
Check the tire pressure (including the spare
at least once a month and always prior to
long distance trips. Tire pressure should be
checked when tires are COLD. COLD tire
pressures are shown on the tire placardaffixed to the inside of the glove box lid.
Incorrect tire pressure may adversely
affect tire life and vehicle handling.
COLD pressure:
After vehicle has been parked for
three hours or more or driven less
than 1 mile (1.6 km) at moderate
speeds.
WARNING
cImproperly inflated tires can fail sud-
denly and cause an accident
c
The vehicle weight capacity is indi-
cated on the F.M.V.S.S. certification
label. Do not load your vehicle be-
yond this capacity. Overloading your
vehicle 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
vehicle components.
cBefore taking a long trip, or when-
ever you heavily load your vehicle,use a tire pressure gauge to ensure
that the tire pressure is at the speci-
fied level.
cDo not drive your vehicle over 85
MPH (140 km/h) unless it is equipped
with high speed rated tires. Driving
faster than 85 MPH (140 km/h) may
result in tire failure, loss of control
and possible injury.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
TYPES OF TIRES
WARNING
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., summer, all season or snow) and
construction. An authorized NISSAN
dealer may be able to help you with

rating and availability. Replacement
tires may have a lower speed rating
than the factory equipped tires, and
may not match the potential maxi-
mum vehicle speed. Never exceed
the maximum speed rating of the
tire.
cFor additional information regarding
tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
All season tires
NISSAN specifies All Season tires on some
models to provide good performance for
use all year around, including snowy and icy
road conditions. All Season Tires are iden-
tified by ``ALL SEASON'' and/or ``M&S'' on
the tire sidewall. Snow tires have better
snow traction than All Season tires and may
be more appropriate in some areas.
Summer tires
NISSAN specifies summer tires on some
models to provide superior performance ondry roads. Summer tire performance in
snow and ice will be substantially reduced.
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, NISSAN recommends the
use of ``SNOW'' or ``ALL SEASON'' tires on
all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
For additional traction on icy roads, studded
tires may be used. However, some U.S.
States and Canadian provinces prohibit
their use. Check local, state and provinciallaws before installing studded tires. Skid
and traction capabilities of studded snow
tires on wet or dry surfaces may be poorer
than that of non-studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.Use only SAE class ``S'' chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chain must be
secured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or undercarriage. If possible, avoid fully
loading your vehicle when using tire chains.
In addition, drive at a reduced speed. Oth-
erwise, your vehicle may be damaged
and/or vehicle handling and performance
may be adversely affected.
Never install tire chains on a TEMPORARY
USE ONLY spare tire.

tires, refer to ``Important Tire Safety
Information'' in the Warranty Infor-
mation Booklet (US) or ``Tire Safety
Information'' in the Warranty and
Roadside Assistance Information
booklet (Canada).
Four-wheel drive models
CAUTION
Always use tires of the same size,
brand, construction (bias, bias-belted
or radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer
case and differential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure andwheel alignment should also be checked
and corrected as necessary. Contact an
authorized NISSAN dealer.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balanc-
ing the front wheels on the vehicle could
lead to transmission damage.
cFor additional information regarding tires,
refer to ``Important Tire Safety Informa-
tion'' in the Warranty Information Booklet
(US) or ``Tire Safety Information'' in the
Warranty and Roadside Assistance Infor-
mation booklet (Canada).
Care of wheels
cWash the wheels when washing the ve-
hicle to maintain their appearance.
cClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.cDo not use abrasive cleaners when
washing the wheels.
cInspect wheel rims regularly for dents or
corrosion. This may cause loss of pres-
sure or damage the tire bead.
cNISSAN recommends waxing the road
wheels to protect against road salt in
areas where it is used during winter.
Spare tire (TEMPORARY USE
ONLY)
Your vehicle may be equipped with a TEM-
PORARY USE ONLY spare tire.
To avoid property damage or personal injury
when using the TEMPORARY USE ONLY
spare tire, observe the following cautions:
WARNING
cThe spare tire should be used for
emergency use only. It should be
replaced with the standard tire at the
first opportunity to avoid possible
tire or differential damage.
cDrive carefully while the TEMPO-
RARY USE ONLY spare tire is in-
stalled. Avoid sharp turns and
abrupt braking while driving.
