Key reminder chime
A chime sounds if the driver side 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
A chime sounds when the driver side door is
opened if the headlights or parking lights
are on (ignition switch is turned off).
Turn the headlight control switch off before
you leave the vehicle.
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 de-
pressed. Have the brakes checked as soon
as possible if the warning sound is heard.
orMalfunction indi-
cator light (MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is running,it may indicate a potential emission control
problem.
The malfunction indicator light will come on
in one of two ways:
1. Malfunction indicator light on steady - An
emission control system malfunction has
been detected. Have the vehicle in-
spected by an authorized NISSAN
dealer. You do not need to have your
vehicle towed to the dealer.
2. Malfunction indicator light blinking - An
engine misfire has been detected which
may damage the emission control sys-
tem. To reduce or avoid emission control
system damage:
cdo not drive at speeds above 45 MPH
(72 km/h).
c
avoid hard acceleration or deceleration.
cavoid steep uphill grades.
cif possible, reduce the amount of cargo
being hauled or towed.
The malfunction indicator light may stop
blinking and come on steady. Have the
vehicle inspected by an authorized 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, which
may affect your warranty coverage.
Some conditions may cause the malfunc-
tion indicator light to come on steady or
blink. Examples are as follows:
cvehicle ran out of fuel, which caused the
engine to misfire.
cfuel filler cap was left off or improperly
installed, allowing fuel to evaporate into
the atmosphere.
If you suspect that you experienced one or
both of the above conditions, drive the ve-
hicle to an authorized NISSAN dealer and
have the vehicle inspected. Avoid any un-
necessary diagnosis during the service by
informing the dealer of the conditions listed
above that may have occurred.

The automatic locking mode should be
used only for child seat installation. Dur-
ing normal seat belt use by a passenger,
the locking mode should not be acti-
vated. If it is activated it may cause
uncomfortable seat belt tension.
Unfastening the belts
To unfasten the belt, press the button on the
buckle. The seat belt automatically retracts.
Shoulder belt height adjustment
(for front seats)
The shoulder belt anchor height should be
adjusted to the position best for you. (See
``Precautions on Seat Belt Usage''.) To ad-
just, press both release buttons and move it
to the desired position so the belt passes
over the center of the shoulder. The belt
should be away from your face and neck,
but not falling off of your shoulder.
WARNING
After adjustment, release the button
and check that it does not move up and
down to make sure the shoulder belt
anchor is securely fixed in position.
Checking seat belt operation
(3-point type with retractor)
Your seat belt retractors are designed to
lock belt movement by two separate meth-
ods:
1) When the belt is pulled quickly from the
retractor.
2) When the vehicle slows down rapidly.
To increase your confidence in the belts,
check the operation as follows:
cGrasp the shoulder belt and pull forward
quickly. The retractor should lock and
restrict further belt movement.
If the retractor does not lock during this
check or if you have any question about belt
operation, see your NISSAN dealer.

2 (Second gear):
Use for hill climbing or engine braking on
downhill grades.
Do not shift into the 2 position at speeds
over 68 MPH (110 km/h). Do not exceed 68
MPH (110 km/h) in the 2 position.
1 (Low gear):
Use this position when climbing steep hills
slowly or driving slowly through deep snow,
sand or mud, or for maximum engine brak-
ing on steep downhill grades.
Do not shift into the 1 position at speeds
over 34 MPH (55 km/h).
Do not exceed 34 MPH (55 km/h) in the 1
position.
Accelerator downshift
Ð In D position Ð
For rapid passing or hill climbing, fully de-
press the accelerator pedal to the floor. This
shifts the transmission down into third gear,
second gear or first gear, depending on the
vehicle speed.
Overdrive switch
ON: For normal driving, push the over-
drive switch ON with the shift lever in
the D position. The transmission is
upshifted into OVERDRIVE as the
vehicle speed increases.
The overdrive does not engage until the
engine has warmed up.
OFF: For driving up and down long slopes
where engine braking would be ad-
vantageous, push the switch OFF.
When cruising at a low speed or
climbing a gentle slope, you may feeluncomfortable shift shocks as the
transmission shifts between 3rd and
overdrive repeatedly. In this case,
set the overdrive switch in the
OFF position. The indicator
light in the instrument panel comes
on at this time.
When driving conditions change, reset the
overdrive switch in the ON position.
Remember not to drive at high speeds for
extended periods of time with the overdrive
switch set in the OFF position. This reduces
fuel economy.

The brake system has two separate hy-
draulic circuits. If one circuit develops a
problem, you will still have braking at
two wheels.
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 the stopping distance will be
longer.
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 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.
Using the brakes
Avoid resting your foot on the brake pedalwhile 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.
WARNING
While 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.The anti-lock brake system controls the
brakes at each wheel 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 varies
the brake fluid pressure to prevent each
wheel from locking and sliding. By prevent-
ing wheel lockup, the system helps the
driver maintain steering control and helps to
minimize 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) to completely stop the vehicle. (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

If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power,
detect abnormal noise, etc., take the follow-
ing steps:
WARNING
cDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
cTo avoid the danger of being
scalded, never remove the radiator
cap while the engine is still hot.
When the radiator cap is removed,
pressurized hot water will spurt out,
possibly causing serious injury.
cDo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road,
apply the parking brake and move the
gearshift lever to Neutral (automatic
transmission to P).
Do not stop the engine.
2. Turn off the air conditioner. Open all the
windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait until
no steam or coolant can be seen before
proceeding.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or
looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water. If coolant is
leaking, the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or to get caught in, the running
fan, belts, or fan motor. The fan motor
can start at any time when the coolant
temperature is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the res-
ervoir tank if necessary. Have your ve-
hicle repaired at the nearest NISSAN
dealer.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze so-
lution contains rust and corrosion inhibitors,
therefore additional cooling system addi-
tives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only an ethylene glycol
anti-freeze with the proper mixture ratio
of 50% anti-freeze and 50% distilled
water. The use of other types of coolant
solutions may damage your cooling
system.

WARNING
cNever remove the radiator cap when
the engine is hot. Wait until the en-
gine and radiator cool down. Seriousburns could be caused by high pres-
sure fluid escaping from the
radiator.
cSee precautions in ``If your vehicle
overheats'' found in the ``In case of
emergency'' section.
cThe radiator is equipped with a pres-
sure cap. Use a genuine NISSAN cap
or its equivalent when replacement
is required.
CHECKING ENGINE COOLANT
LEVEL
With coolant reservoir
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level
is below MIN, add coolant up to the MAX
level. If the reservoir tank is empty, check
the coolant level in the radiatorwhen the
engine is cold.If there is insufficient cool-
ant in the radiator, fill the radiator with
coolant up to the filler opening and also add
it to the reservoir tank up to the MAX level.

If the cooling system frequently requires
coolant, have it checked by your NISSAN
dealer.
CHANGING ENGINE COOLANT
cMajor cooling system repairs should be
performed by your NISSAN dealer. The
service procedures can be found in the
appropriate NISSAN Service Manual.cImproper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
cTo avoid the danger of being
scalded, never change the coolant
when the engine is hot.
cNever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure

normal, it may be due to a lack of adjust-
ment 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 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.
The rear drum brakes (if so equipped) do
not have audible wear indicators. Should
you ever hear an unusually loud noise fromthe 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 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. 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, see
your NISSAN dealer.
