Operating tips
cKeep the windows and sun roof closed
while the air conditioning is in operation.
cAfter parking in the sun, drive for two or
three minutes with the windows open to
vent hot air from the passenger compart-
ment. Then, close the windows. This will
allow the air conditioning to cool the
interior more quickly.cThe air conditioning system should be
operated for about ten minutes at
least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.

cDriving with 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 pres-
sure on the brake pedal will be required
to stop the vehicle and the stopping
distance will be longer.
cDriving with power assisted steering:
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.
However, much greater steering effort is
needed, especially in sharp turns or at
low speeds.
cWet 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 untilthe brakes return to normal. Avoid driving
the vehicle at high speeds until the
brakes function correctly.
cAvoid 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.
cTo 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.
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking actions or
acceleration could cause the wheels to
skid.The anti-lock brake system installed in
some models controls the brakes at each
wheel so the wheels will 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.
It is not necessary to pump the brake
pedal.
Doing so may result in increased stopping
distances.
Normal operation
The 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

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
To 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.
1. Move the vehicle safely off the road,
apply the parking brake and move the
shift lever to Neutral (automatic transmis-
sion to ``P'').
Do not stop the engine.
2. Turn off the air conditioning. Open all the
windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait untilno steam or coolant can be seen before
proceeding.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. 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.
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.
WARNING
Be careful not to allow your hands, hair
or clothing to come into contact with,
or to get caught in, the running fan,
belts, or motor fan.
The fan motor can start at any time
when the coolant temperature is high.If coolant is leaking, the water pump
belt is missing or loose, or the cooling
fan does not run, stop the engine.
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.

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
fluid escaping from the radiator.
1. Perform following procedure to open the
heater water cock:

2. Open the radiator drain plug. Open the
drain plug on the engine water pipe.
3. Open the radiator cap to drain the cool-
ant.
4. Flush the cooling system by running
fresh water through the radiator.
5. Close the radiator drain plug and the
drain plug on the engine water pipe se-
curely.
6. See the ``Technical and consumer infor-
mation'' section for cooling system ca-
pacity. Fill the radiator slowly with the
proper mixture of coolant and water. Fill
the reservoir tank up to the ``MAX'' level.
7. Open and close the air release plug to
release air. Then fill the radiator again
and install the radiator cap.8. Start the engine, and warm it up until it
reaches normal operating temperature.
Then race the engine 2 or 3 times under
no load. Watch the coolant temperature
gauge for signs of overheating.
9. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up to the
``MAX'' level.
10. Open and close the air release plug to
release air. Then fill the radiator again
and install the radiator cap.11. Check the radiator drain plug and the
