2002 NISSAN FRONTIER brakes

WARNING LIGHTS
orAnti-lock brake warn-
ing light
If the light comes on while the engine is
running, it may indicate the anti-lock brake
system is not functioning properly. Have the
system checked by an authorized NISSAN
dealer.
If an abnormality occurs in the system, the
anti-lock function ceases but the ordinary
brakes continue to operate normally.
If the light comes on while you are driving,
contact an authorized NISSAN dealer for
repair.
Automatic transmission oil
temperature warning light
(
model)
This light comes on when the automatic
transmission oil temperature is too high. If
the light comes on while driving, reduce the
vehicle speed as soon as safely possible
until the light turns off.
CAUTION
Continued vehicle operation when the
A/T oil temperature warning light is on
may damage the automatic transmis-
sion.
Automatic transmission park
warning light (
model)
This light indicates that the automatic trans-
mission parking function is not engaged. If
the transfer control shift lever is not secured
in any drive position while the automatic
transmission selector lever is in the P (Park)
position, the vehicle may move unexpect-
edly.
Shift the transfer control shift lever into the
2H, 4H, or 4L position when the warning
light comes on.
cWhen parking, always make sure that the
transfer control shift lever is in 2H, 4H, or
4L and the parking brake is set.
cIf the ATP light is ON, this indicates that
the automatic transmission P (Park) po-
sition will not function and the transfer
control shift lever is in the N (Neutral)
position.c
Failure to engage the transfer control shift
lever in 2H, 4H, or 4L could result in the
vehicle moving unexpectedly, resulting in
serious personal injury or property dam-
age.
WARNING
cIf the ATP light is ON, this indicates
that the automatic transmission P
(Park) position will not function and
the transfer control shift lever is in
the N (Neutral) position.
orBrake warning
light
This light functions for both the parking
brake and the foot brake systems.
When the ignition key is in the ON position,
the light comes on when the parking brake
is applied and also warns of a low brake
fluid level. If the light comes on while the
engine is running with the parking brake not
applied, stop the vehicle and perform the
following:
1.
Check the brake fluid level. Add brake fluid
as necessary. See ``Brake and clutch fluid''

cif possible, reduce the amount of cargo
being hauled or towed.
The malfunction indicator lamp may stop
blinking and come on steady.
Have the vehicle inspected by an autho-
rized NISSAN dealer. You do not need to
have your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without
having the emission control system
checked and repaired as necessary
could lead to poor driveability, reduced
fuel economy, and possible damage to
the emission control system.
Overdrive off indicator light
(automatic transmission
only)
This light comes on when the overdrive
switch is pushed to the OFF position.
Turn signal/hazard indicator
lights
These lights flash when the turn signal
switch or hazard switch is turned on.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear
warnings. When a brake pad requires re-
placement, it makes a high pitched scraping
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 warning sound is heard.
Key reminder chime
The chime sounds when the driver's door is
opened and the key is left in the ignition
switch. Take the ignition key when you
leave the vehicle.
Light reminder chime
A chime sounds if the driver's door is
opened with the headlight switch on unless
the ignition key is in the ON position. Turn
the headlight switch off when you leave the
vehicle.
VEHICLE SECURITY SYSTEM
(if so equipped)
The vehicle security system provides visual
and audio alarm signals if parts of the
vehicle are disturbed.

(manual transmission vehicles), us-
ing only the brake, as this could
cause loss of control.
cHeavy braking going down a hill
could cause your brakes to overheat
and fade, resulting in loss of control
and an accident. Apply brakes lightly
and use a low gear to control your
speed.
cUnsecured cargo can be thrown
around when driving over rough ter-
rain. Properly secure all cargo so it
will not be thrown forward and cause
injury to you or your passengers.
cTo avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so
equipped) and evenly distribute the
load. Secure heavy loads in the
cargo area as far forward and as low
as possible. Do not equip the vehicle
with tires larger than specified in this
manual. This could cause your ve-
hicle to roll over.
cDo not grip the inside or spokes of
the steering wheel when driving off-
road. The steering wheel could movesuddenly and injure your hands. In-
stead drive with your fingers and
thumbs on the outside of the rim.
cBefore operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.
cAlways drive with the floor mats in
place as the floor may become hot.
cLower your speed when encounter-
ing strong crosswinds. With a higher
center of gravity, your NISSAN is
more affected by strong side winds.
Slower speeds ensure better vehicle
control.
cDo not drive beyond the perfor-
mance of the tires, even with 4WD
engaged.
cAccelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
cIf at all possible, avoid sharp turning
maneuvers, particularly at high
speeds. Your NISSAN four-wheel
drive vehicle has a higher center of
gravity than a two-wheel drive veh-icle. The vehicle is not designed for
cornering at the same speeds as
conventional two-wheel drive ve-
hicles. Failure to operate this vehicle
correctly could result in loss of con-
trol and/or a roll over accident.
cAlways use tires of the same type,
size, brand, construction (bias, bias-
belted, or radial), and tread pattern
on all four wheels. Install tire chains
on the rear wheels when driving on
slippery roads and drive carefully.
cBe sure to check the brakes immedi-
ately after driving in mud or water.
See(Brake system(later in this sec-
tion for(Wet brakes(.
cAvoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.
cWhenever you drive off-road
through sand, mud or water as deep
as the wheel hub, more frequent-
maintenance may be required. See
(Periodic maintenance(in the(Main-
tenance and do-it-yourself(section
of this manual.

Place the shift lever in the R (Reverse)
position. When parking on an uphill
grade, place the shift lever in the 1st
position.
Automatic transmission models:
Move the selector lever to the P (Park)
position.
3. To help prevent the vehicle from rolling
into the street when parked on an incline,
it is a good practice to turn the wheels as
illustrated.
cHEADED DOWNHILL WITH CURB:
s1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
cHEADED UPHILL WITH CURB:
s2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
cHEADED UPHILL OR DOWNHILL, NO
CURB:
s3
Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Turn the ignition key to the LOCK posi-
tion and remove the key.The power assisted steering is designed to
use a hydraulic pump, driven by the engine,
to assist steering.
If the engine stops or drive belt breaks, you
will still have control of the vehicle. How-
ever, much greater steering effort is
needed, especially in sharp turns and at low
speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be much harder to operate.The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
BRAKING PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on
the brake pedal will be required to stop the
vehicle and stopping distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake linings and pads faster,
and reduce gas mileage.
To help reduce brake wear, and to prevent
the brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade.

WARNING
cWhile driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an acci-
dent.
cIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As a
result, your braking distance will be longer
and the vehicle may pull to one side during
braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal
to heat the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function cor-
rectly.
ANTI-LOCK BRAKE SYSTEM
(ABS)
Using the system (4-wheel ABS)
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Using the system (2-wheel rear ABS)
Depress the brake pedal and hold it down.
With the rear anti-lock brake system, the
front wheels can still lock. If this happens,
release the brake pedal slightly and then
reapply pressure.
Normal Operation
The anti-lock brake system does not oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h). (The speeds vary according to road
conditions.)
When driving, the anti-lock brake system
controls the wheels so they will not lock
when braking abruptly or when braking on aslippery road. Thus, difficult steering and
swerving of the vehicle due to locked
wheels is minimized. The system detects
the wheel rotation rate and electronically
controls the pressure applied to each brake.
Slight vibration on the brake pedal accom-
panied by noise usually occurs while the
ABS system is operating. Such vibration
and noise encountered during abrupt brak-
ing is not a problem, but indicates that the
system is functioning.
Self-test feature
The anti-lock brake system consists of elec-
tronic sensors and hydraulic solenoids con-
trolled by a computer. The computer has a
built-in diagnostic feature that tests the sys-
tem each time you start the engine and
move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you
may hear a ``clunk'' noise and/or feel a
pulsation in the brake pedal. This is normal
and is not an indication of any malfunction. If
the computer senses any malfunction, it
switches the anti-lock brake system off and
turns on the ABS brake warning light in the
dashboard. The brake system then operates
normally, but without anti-lock assistance.
5-26Starting and driving
ZX

If an abnormality occurs in the system, the
anti-lock function will cease but the ordinary
brakes will continue to operate normally. The
ABS brake warning light will then come on.
If the light comes on while you are driv-
ing, contact an authorized NISSAN
dealer for repair.
WARNING
cThe anti-lock brake system is a so-
phisticated device, but it cannot pre-
vent accidents resulting from care-
less or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces, but remember that the
stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with the anti-lock
brake system. Stopping distances
may also be longer on rough, gravel,
or snow covered roads, or if you are
using tire chains. Always maintain a
safe distance from the vehicle in
front of you. Ultimately, the respon-
sibility for safety of self and others
rests in the hands of the driver.Tire type and condition may also
affect braking effectiveness.
cWhen replacing tires, install the
specified size of tires on all four
wheels.
cWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
``Tire placard'' in the ``Technical and
consumer information'' section of
this manual.
For additional information, refer to9Wheels
and Tires9in the9Maintenance and do-it-
yourself9section of this manual.
FREEING A FROZEN DOOR
LOCK
To prevent a door lock from freezing, apply
de-icer or glycerin through the key hole. If
the lock becomes frozen, heat the key be-
fore inserting it in the key hole.
ANTI-FREEZE
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check anti-freeze (ethylene glycol base) to
assure proper winter protection. For details,
see ``Engine cooling system'' in the ``Main-
tenance and do-it-yourself'' section of this
manual.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Maintenance
and do-it-yourself'' section of this manual.

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-
