the fuel filler cap is installed and closed tightly,
and that the vehicle has at least 3 gallons (11.4
liters) of fuel in the fuel tank.
After a few driving trips, the
lamp should
turn off if no other potential emission control
system malfunction exists.
If this indicator lamp comes on steady for 20
seconds and then blinks for 10 seconds when
the engine is not running, it indicates that the
vehicle is not ready for an emission control sys-
tem inspection/maintenance test. See “Readi-
ness for inspection/maintenance (I/M) test” in the
“Technical and consumer information” section of
this manual.
Operation
The malfunction indicator lamp will come on in
one of two ways:
cMalfunction indicator lamp on steady — An
emission control system malfunction has
been detected. Check the fuel filler cap. If
the fuel filler cap is loose or missing, tighten
or install the cap and continue to drive the
vehicle. The
lamp should turn off after
a few driving trips. If thelamp does
not turn off after a few driving trips, have the
vehicle inspected by a NISSAN dealer. You
do not need to have your vehicle towed to
the dealer.cMalfunction indicator lamp blinking — An
engine misfire has been detected which may
damage the emission control system. To re-
duce or avoid emission control system dam-
age:
– do not drive at speeds above 45 MPH
(72 km/h) .
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if 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
a NISSAN dealer. You do not need to have your
vehicle towed to the dealer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
Overdrive off indicator light
(automatic transmission mod-
els only)
This light comes on when the overdrive function
is OFF.
The automatic transmission overdrive function is
controlled by the overdrive switch.
See “Driving the vehicle” in the “Starting and
driving” section of this manual.
Turn signal/hazard indicator
lights
The appropriate light flashes when the turn signal
switch is activated.
Both lights flash when the hazard switch is turned
on.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear warnings.
When a brake pad requires replacement, 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.

The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
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 hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE 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 dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brakes 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. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating 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 the 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.
ANTI-LOCK BRAKE SYSTEM (ABS)
(if so equipped)
The anti-lock brake system controls the brakes so
the wheels do not lock when braking abruptly or
when braking on slippery surfaces. The system
detects the rotation speed at each wheel and

Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front (and rear, if so equipped) disc-type
brakes self-adjust every time the brake pedal is
applied. The rear drum-type brakes also 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. To adjust, apply the parking brake
several times.
WARNING
See a NISSAN dealer for a brake system
check 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 re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard 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 maybe 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 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 a NISSAN dealer.
Proper brake inspection intervals should
be followed.For more information regarding
brake inspections, see the appropriate mainte-
nance schedule information in the “NISSAN Ser-
vice and Maintenance Guide”.
BRAKE BOOSTER
Check the brake booster function as follows:
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 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.
If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
