2003 NISSAN PATHFINDER brake pads

transfer 4LO position indicator light turns on
when you shift the 4WD shift switch to 4LO.
The indicator light may blink while shifting
from one drive mode to the other.
Turn signal/hazard indicator
lights
The light flashes when the turn signal switch
lever or hazard switch is turned on.
Vehicle dynamic control off
indicator light (if so equipped)
The light comes on when the vehicle dynamic
control off switch is pushed to OFF. This indi-
cates the vehicle dynamic control system and
traction control system are not operating. When
the vehicle dynamic control off indicator light and
slip indicator light come on with the vehicle
dynamic control system turned on, this light
alerts the driver to the fact that the vehicle
dynamic control system’s fail-safe mode is op-
erating, i.e. the vehicle dynamic control system
may not be functioning properly. Have the sys-
tem checked by your NISSAN dealer. If an
abnormality occurs in the system, the vehicle
dynamic control system function will be can-
celed but the vehicle is still driveable. For addi-
tional information, see “Vehicle dynamic control
system (VDC)” in the “5. Starting and driving”
section of this manual.
AUDIBLE REMINDERS
Key reminder chimeThe chime will sound when the driver side door
is opened if the key is left in the ignition switch.
Take the ignition key when you leave the vehicle.Light reminder chimeThe chime will sound when the front door is
opened with the headlight switch on unless the
ignition key is in the ignition switch.Brake pad wear warningThe disc brake pads have audible wear warn-
ings. When a brake pad requires replacement, it
will make a high pitched scraping sound. Have
the brakes checked as soon as possible if the
warning sound is heard when the vehicle is
moving, whether or not the brake pedal is de-
pressed.Your vehicle may have two types of security
system, as follows:

Vehicle security system

Nissan Vehicle Immobilizer System
The security condition will be shown by the
security indicator light.
VEHICLE SECURITY SYSTEMThe vehicle security system provides visual and
audio alarm signals if parts of the vehicle are
disturbed.

BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.Vacuum assisted brakeThe 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 the stopping
distance will be longer.Using the brakesAvoid 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 save the brakes and to prevent the
brakes from overheating, before going down a
slope or long grade, reduce speed and down-
shift to a lower gear.Wet brakesWhen 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 brakes, drive the vehicle at a safe speed
while lightly pressing the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.
WARNING

While 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.

If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.ANTI-LOCK BRAKE SYSTEM (ABS)The anti-lock brake system controls the brakes
at each wheel so the wheels will not lock when
braking abruptly or when braking on slippery
surfaces. The system detects the rotation speed
at each wheel and varies the brake fluid pressure
to prevent each wheel from locking and sliding.
By preventing wheel lockup, the system helpsthe driver maintain steering control and helps to
minimize swerving and spinning on slippery sur-
faces.
Using the systemDepress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.Normal operationThe anti-lock brake system will not operate at
speeds below 3 to 6 MPH (5 to 10 km/h) to
completely stop the vehicle. (The speeds will
vary according to road conditions.) When the
anti-lock system senses that one or more wheels
are close to locking up, the actuator (under the
hood) rapidly applies and releases hydraulic
pressure (like pumping the brakes very quickly).
While the actuator is working, you may feel a
pulsation in the brake pedal and hear a noise or
vibration from the actuator under the hood. This
is normal and indicates that the anti-lock system
is working properly. However, the pulsation may
indicate that road conditions are hazardous and

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 au-
dible wear indicators. When a brake pad re-
quires 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, occa-
sional 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 nothave audible wear indicators. Should you ever
hear an unusually loud noise from the rear drum
brakes, have them inspected as soon as pos-
sible by your NISSAN dealer.
Proper brake inspection intervals should
be followed.For additional information, see the
separate “Service and Maintenance Guide”.
BRAKE BOOSTERCheck the brake booster function with the fol-
lowing 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 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 de-
pressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradually
with each depression as the vacuum is re-
leased from the booster.
