2002 NISSAN ALTIMA brakes

The malfunction indicator lamp may stop
blinking and come on steady. Have the
vehicle inspected by an authorized NISSAN
dealer. You do not need to have your ve-
hicle 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.
Traction control off indicator
light
After turning the ignition key to the ON
position, the light will illuminate. The light
will turn off after about 2 seconds if the
traction control system (TCS) is operational.
If the light stays on or comes on when you
are driving, it may indicate the traction con-
trol system is not functioning properly. Have
the system checked by your NISSAN
dealer.The light comes on when the traction control
off switch is pushed to OFF. This indicates
the traction control system is not operating.
Push the traction control off switch again or
restart the engine and the system will oper-
ate normally. See ªTraction controlº in the
ª5. Starting and drivingº section.
Slip indicator light
This indicator will blink when the traction
control system is limiting wheelspin. Slip-
pery road conditions may exist if the slip
indicator blinks on. If this happens, adjust
your driving accordingly.
The slip indicator light also comes on when
you turn the ignition key to ON. The light will
turn off after about 2 seconds if the system
is operational. If the light does not come on
or go off, have the traction control system
checked by your NISSAN dealer. The sys-
tem operates in all transmission shift lever
positions. But the system can upshift the
transmission only as high as the indicated
shift lever position.
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 pos-
sible if the warning sound is heard.
Key reminder chime
A chime sounds if the driver's door is
opened while the key is left in the ignition
switch. Remove the key and take it with you
when leaving the vehicle.
Light reminder chime
With the ignition switch in the OFF position,
a chime sounds when the driver's door is
opened with the headlight switch on.
Turn the headlight switch OFF when leaving
the vehicle.

cCold engine idle speed is high, so
use caution when shifting into a for-
ward or reverse gear before the en-
gine has warmed up.
cNever shift to P (Park) or R (Reverse)
while vehicle is moving. This could
cause an accident.
cOn slippery roads, do not downshift.
This may cause a loss of control.
CAUTION
When stopping the vehicle on an uphill
grade, do not hold the vehicle by de-
pressing the accelerator pedal. The
foot brakes should be used for this
purpose.
Shifting
After starting the engine, fully depress the
brake pedal and shift the selector lever from
P (Park) to R (Reverse), D (Drive), 3, 2 or 1.
WARNING
Apply the parking brake if the selector
lever is in any position while the engine
is not running. Failure to do so could
cause the vehicle to move unexpect-
edly or roll away and result in serious
personal injury or property damage.
If the key is turned to OFF or ACC for any
reason while the vehicle is in N (Neutral), or
any D (Drive) position, the selector lever
cannot be moved to P (Park). Additionally,
the key cannot be turned to LOCK and be
removed from the ignition switch. If this
occurs, perform the following steps:
1. Apply the parking brake when the vehicle
is stopped.
2. Turn the key to ON.
3. Depress the foot brake pedal.
4. Move the selector lever to P (Park) or N
(Neutral) to restart the vehicle (P is pre-
ferred). Move the selector lever to P
(Park) to park the vehicle and turn the
ignition key to LOCK to remove the key.

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 the hydraulic pump
drive belt breaks, you will still have control of
the vehicle. However, much greater steer-
ing 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
hydraulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKING PRECAUTIONS
Vacuum assisted brake
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 overheats the brakes,
increases wear on the brake linings and
pads, and reduces gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down
a slope or long grade. Overheated brakes
may reduce braking performance and could
result in loss of vehicle control.
Parking brake bedding
The parking brake shoes must be ``bedded
down'' whenever the stopping effect of the

parking brake is weakened or whenever the
parking brake shoes and/or drums are re-
placed, in order to assure the best braking
performance.
This procedure is described in the Vehicle
service manual and can be performed by
your NISSAN dealer.
WARNING
c
While driving on a slippery surface,
be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.
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 brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedalto heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
ANTI-LOCK BRAKE SYSTEM
(ABS) (if so equipped)
The anti-lock brake system installed in
some models controls the brakes at each
wheel so the wheels do not lock when
braking abruptly or when braking on slip-
pery surfaces. The system detects the rota-
tion speed at each wheel and varies the
brake fluid pressure to prevent each wheel
from locking and sliding. By preventing
wheel lockup, the system helps the driver
maintain steering control and helps to mini-
mize swerving and spinning on slippery
surfaces.
Using the system
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
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 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 pres-
sure (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 extra
care is required while driving.
Self-test feature
The anti-lock brake system is sophisticated,
with electronic sensors, electric pumps, and
hydraulic solenoids controlled by a com-
puter. The computer has a built-in diagnos-
tic feature that tests the system 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 indica-

seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints move up and
down smoothly and the locks (if so
equipped) hold securely in all latched posi-
tions.
Seat beltsCheck that all parts of the seat
belt system (e.g., buckles, anchors, adjust-
ers and retractors) operate properly and
smoothly, and are installed securely. Check
the belt webbing for cuts, fraying, wear or
damage.
Accelerator pedalCheck the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mat away from the pedal.

Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear, disc-type brakes self-
adjust every time the brake pedal is applied.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it makes 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.
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 as fol-
lows:
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. Keep 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, see an
authorized NISSAN dealer.

TOWING SAFETY
Trailer hitch
Choose a proper hitch for your vehicle and
trailer. A genuine NISSAN trailer hitch is
available from your NISSAN dealer
(Canada only). Make sure the trailer hitch is
securely attached to the vehicle, to help
avoid personal injury or property damage
due to sway caused by crosswinds, rough
road surfaces or passing trucks.
CAUTION
cDo not use axle-mounted hitches.
cThe hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.
cDo not modify the vehicle exhaust
system, brake system, etc. to install
a trailer hitch.
cTo reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.
cAfter the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.
cRegularly check that all hitch mount-
ing bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (located
under the center console lid).cTrailer tire condition, size, load rating and
proper inflation pressure should be in
accordance with the trailer and tire
manufacturer's specifications.
Safety chains
Always use suitable chains between your
vehicle and the trailer. Safety chains should
be crossed and should be attached to the
hitch, not to the vehicle bumper or axle. Be
sure to leave enough slack in the chains to
permit turning corners.
Trailer lights
Trailer lights should comply with federal
and/ or local regulations. When wiring the
vehicle for towing, connect the stop and tail
light pickup into the vehicle electrical circuit.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to Federal
and/or local regulations and that it is prop-
erly installed.

speed. This combination will help stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember, the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
cAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change the trans-
mission fluid more frequently. For addi-
tional information see the ``Maintenance
and do-it-yourself'' section earlier in this
manual.DOT (Department of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Tempera-
ture A
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment test courses. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. However,
relative tire performance depends on actual
driving conditions, and may vary signifi-
cantly due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction AA, A, B and C
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades repre-sent the tire's ability to stop on wet pave-
ment as measured under controlled condi-
tions on specified government test surfaces
of asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.
Temperature A, B and C
Temperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate
heat when tested under controlled condi-
tions on a specified indoor laboratory test
wheel. Sustained high temperature can
cause tire material to degenerate, reducing
tire life. Excessive temperatures can lead to
sudden tire failure. Grade C corresponds to
a performance level which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A
and B represent higher levels of perfor-
mance on laboratory test wheels than the
minimum required by law.
