ment. Then, close the windows. This
allows the air conditioner to cool the
interior more quickly.
cThe air conditioning system should be
operated for approximately ten min-
utes at least once a month. This helps
prevent damage to the system due to
lack of lubrication.
cIf the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turnthe air conditioner off. See ``If your
vehicle overheats'' in the ``In case of
emergency'' section of this manual.

The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
BRAKING 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 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.
WARNING
cWhile 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.
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 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 preventing wheel
lockup, the system helps the driver maintain
steering control and helps to minimize swerv-
ing 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

cMake sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal.
5. Start the engine of the booster vehicle
and let it run for a few minutes.
6. Keep the engine speed of the booster
vehicle at about 2,000 rpm, and start the
engine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged
for more than 10 seconds. If the engine
does not start right away, turn the key
off and wait 3 to 4 seconds before
trying again.
7. After starting the engine, carefully dis-
connect the negative cable and then the
positive cable.
8. Be sure to dispose of the cloth used to
cover the vent holes as it may be con-
taminated with corrosive acid.
CAUTION
cAutomatic transmission models can-
not be push started. This may cause
transmission damage.
cThree way catalyst equipped models
should not be started by pushing.
The three way catalyst may be dam-
aged.
cNever try to start the vehicle by tow-
ing it. When the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle.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
selector lever to N (Neutral) (manual
transmission) or the shift selector lever to
P (Park) (automatic transmission).
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

If the cooling system frequently requires
coolant, have it checked by an autho-
rized NISSAN dealer.
CHANGING ENGINE COOLANT
cMajor cooling system repairs should be
performed by an authorized NISSAN
dealer. The service procedures can be
found in the 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.
cAvoid direct skin contact with used
coolant. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.cKeep coolant out of reach of children
and pets.
Engine coolant must be disposed of
properly. Check your local regulations.

ever, you may use unleaded gasoline with
an octane rating as low as 85 AKI (Anti-
Knock Index) in high altitude areas (over
4,000 ft [1,219 m]) such as: Colorado, Mon-
tana, New Mexico, Utah, Wyoming, north-
eastern Nevada, southern Idaho, western
South Dakota, western Nebraska, and the
part of Texas which is directly south of New
Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ``spark knock.'' (``Spark
knock'' is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady
speed on level roads, have an authorized
NISSAN dealer correct the condition.
Failure to correct the condition is misuse
of the vehicle, for which NISSAN is not
responsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or
engine damage. If any of the above symp-
toms are encountered, have your vehiclechecked at an authorized NISSAN dealer or
other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
not a cause for concern, because you
get the greatest fuel benefit when there
is light spark knock for a short time
under heavy engine load.
