Engine coolant temperature gauge
The gauge indicates the engine coolant
temperature.
The engine coolant temperature varies with
the outside air temperature and driving con-
ditions.
CAUTION
cIf the gauge indicates engine coolant
temperature over the normal range,
stop the vehicle as soon as safely
possible. If the engine is overheated,
continued operation of the vehicle
may seriously damage the engine.
See the ``In case of emergency'' sec-
tion for immediate action required.
Fuel gauge
The gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during brak-
ing, turning, acceleration, or going up or
down hills.
The gauge needle remains in approximately
the same position even when the ignition
key is turned to OFF.
The warning indicator light comes on when
the amount of fuel in the tank is getting low.
Refill the fuel tank before the gauge
registers E (Empty).
CAUTION
cIf the vehicle is driven with the fuel
level very low, the malfunction indi-
cator light may come on. Refuel as
soon as possible. After driving for a
while, the light should remain off. If
the light remains on, have the ve-
hicle inspected by an authorized
NISSAN dealer.

3. Move the fan control dial to the desired
position.
4. Push on the air conditioner button. The
indicator light comes on.
5. Move the temperature control lever to the
desired position.
Dehumidified defogging
This mode defogs the windows and dehu-
midifies the air.
1. Push the
button in.
When the
position is selected, the
air conditioner automatically turns on
(however, the indicator light will not illu-
minate). This dehumidifies the air which
helps defog the windshield. The air recir-
culation mode automatically turns off,
allowing outside air to be drawn into the
passenger compartment which helps de-
fog the windshield.
2. Move the fan control dial to the desired
position.
3. Move the temperature control lever to the
desired position.
Outside air is drawn into the passengercompartment to improve the defogging per-
formance.
Operating tips
cKeep the windows and sun roof closed
while the air conditioner 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
allows the air conditioner to cool the
interior more quickly.
cThe air conditioner 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
exceeds the H (hot) position, turn the air
conditioner off. See ``If your vehicle over-
heats'' in the ``In case of emergency''
section of this owner's manual for addi-
tional information.

while driving, take the vehicle to an autho-
rized NISSAN dealer for repair.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent
accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces, but re-
member that the stopping distance on
slippery surfaces will be longer than on
normal surfaces, even with the anti-
lock system. Stopping distances may
also be longer on rough, gravel or
snow covered roads, or if you are using
tire chains. Always maintain a safe dis-
tance from the vehicle in front of you.
Ultimately, the responsibility for safety
of self and others rests in the hands of
the driver.
Tire type and condition of tires may
also affect braking effectiveness.
cWhen replacing tires, install the
specified size of tire on all 4 wheels.cWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
ªTire placardº in the Owner's Manual
index.
Refer to ``Wheels and Tires'' in the
``Do-it-yourself'' section of this manual.
Freeing a frozen door lock
To prevent a door lock from freezing, apply
de-icer or glycerin through the key hole. If
the lock becomes frozen, heat the key be-
fore inserting it into the key hole.
Anti-freeze
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check the anti-freeze (ethylene glycol base)
to assure proper winter protection. For de-
tails, see ``Engine cooling system'' in the
``Do-it-yourself'' section.
Battery
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Do-it-yourself ''
section.
Draining of coolant
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the
radiator and on the engine block. Refill

Tire equipment
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON tires on all four
wheels. Please consult an authorized
NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
U.S. States and Canadian Provinces pro-
hibit their use. Check local, state and
provincial laws before installing studded
tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may
be poorer than that of non-studded snow
tires.
3. Tire chains may be used. Make sure they
are the proper size for the tires on yourvehicle and are installed according to the
chain manufacturer's suggestions.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are installed
according to the chain manufacturer's sug-
gestions.Use only SAE Class ``S'' chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tight
fit. Loose end links of the tire chain must be
secured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or underbody. If possible, avoid fully loading
your vehicle when using tire chains. In ad-
dition, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or ve-
hicle handling and performance may be
adversely affected.
Never install tire chains on T-type spare
tires. Do not use tire chains on dry roads.
Special winter equipment
It is recommended that the following items
be carried in the vehicle during winter:
1. A scraper and stiff-bristled brush to re-move ice and snow from the windows
and wiper blades.
2. A sturdy, flat board to be placed under
the jack to give it firm support.
3. A shovel to dig the vehicle out of snow-
drifts.
4. Extra window washer fluid to refill the
reservoir tank.
Driving on snow or ice
WARNING
cWet ice (32ÉF, 0ÉC and freezing rain),
very cold snow or ice can be slick
and very hard to drive on. The ve-
hicle will have a lot less traction or
``grip'' under these conditions. Try to
avoid driving on wet ice until the
road is salted or sanded.
cWhatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels
will lose even more traction.

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 an authorized NISSAN
dealer.When towing your vehicle, U.S. States,
Canadian Provinces and local regulations
for towing must be followed. Incorrect tow-
ing equipment could damage your vehicle.
Towing instructions are available from an
authorized NISSAN dealer. Local service
operators will generally be familiar with the
applicable laws and procedures for towing.
To assure proper towing and to prevent
accidental damage to your vehicle, NISSAN
recommends that you have a service opera-
tor tow your vehicle. It is advisable to have
the service operator carefully read the fol-
lowing precautions:
WARNING
cNever ride in a vehicle that is being
towed.
cNever get under your vehicle after it
has been lifted by a tow truck.
CAUTION
cWhen towing, make sure that the
transmission, axles, steering system
and powertrain are in working con-
dition. If any unit is damaged, dollies
must be used.

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 engine cooling system
additives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only an ethelene glycol anti-
freeze with the proper mixture ratio of
50% Genuine Nissan Anti-freeze coolant
or equivalent and 50% demineralized
water or distilled water. The use of other
types of coolant solutions may damage
the engine cooling system.

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