With the engine running, check distance A
between the upper surface of the pedal and
the metal floor.
Distance A:
4-3/4 in (120 mm) or more
If it is out of the range shown above, see
your NISSAN dealer.
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
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.
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 brakeschecked 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 your NISSAN
dealer.
Proper brake inspection intervals should
be followed.For more information regard-
ing brake inspections, see the appropriate
maintenance schedule information in the
``Maintenance Schedule'' section of this
manual.

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-
crease gradually 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.Press 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.

If you have a flat tire, see the ``In case of
emergency'' section.
Maximum inflation pressure
Do not exceed the maximum inflation pres-
sures shown on the side wall of the tire.
Tire inflation pressure
Periodically check the tire pressure (includ-
ing spare). Tire pressure should be checked
when tires are COLD. COLD tire pressures
are shown on the tire placard affixed to the
glove box lid.
Incorrect tire pressure may adverselyaffect 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).
CAUTION
cThe vehicle weight capacity is indi-
cated on the tire placard. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may result
in reduced tire life, unsafe operating
conditions due to premature tire fail-
ure, or unfavorable handling charac-
teristics and could also lead to a
serious accident. Loading beyond
the specified capacity may also re-
sult in failure of other vehicle
components.
cBefore taking a long trip, or when-
ever you have loaded your vehicle
heavily, use a tire pressure gauge to
ensure that the tire pressure is at the
specified level.
cDo not drive your vehicle over 85
MPH (140 Km/h) unless it is
equipped with high capability tires.Driving faster than 85 MPH (140
Km/h) may result in tire failure, loss
of control and possible injury.
Types of tires
CAUTION
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. Your NISSAN dealer may
be able to help you with information
about tire type, size, speed rating and
availability. Replacement tires may
have a lower speed rating than the
factory equipped tires, and may not
match the potential maximum vehicle
speed. Never exceed the maximum
speed rating of the tire.
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
DI0047
WHEELS AND TIRES
7-24
ZX

Page 148 of 198

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 on
dry 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.
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 prov-inces and states prohibit their use. Check
local, state and provincial laws before in-
stalling studded tires. Skid and traction ca-
pabilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
4-wheel drive model
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
CAUTION
ONLY use spare tires specified for each
4-wheel drive model.
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 besecured 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.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress. When driv-
ing on clear paved roads, be sure to change
to 2WD.

Tire rotation
NISSAN recommends rotating the tires ev-
ery 7,500 miles (12,000 km) for 2WD ve-
hicles and every 3,750 miles (6,000 km) for
4WD vehicles.
See ``Flat tire'' in the ``In case of emergency''
section for tire replacing procedures.
Wheel nut tightening torque:
87 to 108 ft-lb (118 to 147 Nzm)
CAUTION
cAfter rotating the tires, adjust the tire
pressure.
cRetighten the wheel nuts after the
wheels have been run for the first
600 miles (1,000 km) (also in cases of
a flat tire, etc.).
cDo not include the TEMPORARY
USE ONLY spare tire in the tire rota-
tion.
Tire wear and damage
CAUTION
cTires should be periodically in-
spected for wear, cracking, bulging
or objects caught in the tread. If
excessive wear, cracks, bulging or
deep cuts are found, the tire should
be replaced.
cThe original tires have a built-in
tread wear indicator. When the wear
indicator is visible, the tire should be
replaced.

cImproper service for a TEMPORARY
USE ONLY spare tire may result in
serious personal injury. If it is nec-
essary to repair the TEMPORARY
USE ONLY spare tire, contact your
NISSAN dealer.
Changing tires and wheels
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. Recommended types
and sizes are shown in ``Wheel/tire size'' in
the ``Technical and consumer information''
section. The use of tires other than those
recommended or the mixed use of tires of
different brands, construction (bias, bias-
belted or radial), or tread patterns can ad-
versely affect the ride, braking, handling,
ground clearance, body-to-tire clearance,
snow chain clearance, speedometer cali-
bration, headlight aim and bumper height.
Some of these effects may lead to acci-
dents and could result in serious per-
sonal injury.
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a differ-ent offset could cause early tire wear, poor
vehicle handling characteristics and/or in-
terference with the brake discs/drums. Such
interference can lead to decreased braking
efficiency and/or early brake pad/shoe
wear.
CAUTION
Do not install a deformed wheel or tire
even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warning.
4-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 and
wheel alignment should also be checked
and corrected as necessary. Contact your
NISSAN dealer.
CAUTION
ONLY use spare tires specified for each
4-wheel drive model.
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.
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.
