TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (r/min).
CAUTION
When engine speed approaches the
red zone, shift to a higher gear. Oper-
ating the engine in the red zone may
cause serious engine damage.
ENGINE COOLANT TEMPERA-
TURE GAUGE
The gauge indicates the engine coolant
temperature.
The engine coolant temperature varies with
the outside air temperature and driving con-
ditions.
CAUTION
If the gauge indicates engine coolant
temperature over the normal range,
stop the vehicle as soon as safely pos-
sible. If the engine is overheated, con-
tinued operation of the vehicle may
seriously damage the engine. See the
``In case of emergency'' section for
immediate action required.

2. Push thebutton in.
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 passenger
compartment 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.

The brake system then operates normally,
but without anti-lock assistance.
If the light comes on during the self-test or
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 brake 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 four
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 ``Technical and
Consumer information'' section of
this manual.
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 WATER
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the

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 get caught in, engine belts or
the engine cooling fan. The engine
cooling 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, all State (Provin-
cial in Canada) and local regulations for tow-
ing must be followed. Incorrect towing equip-
ment 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 having a
service operator tow your vehicle. It is advis-
able to have the service operator carefully
read the following 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.
cAlways attach safety chains before
towing.

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% soft tap water.
The use of other types of coolant solu-
tions may damage the engine cooling
system.

WARNING
cNever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
c
The radiator is equipped with a pres-
sure type radiator cap. To prevent
engine damage, use only a genuine
NISSAN radiator cap.
CHECKING ENGINE COOLANT
LEVEL
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.

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 an 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.
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.
Perform the following procedure to open the
heater water cock:
1. Turn the ignition switch ON and set the
temperature control lever to the maxi-
mum hot position. Wait 10 seconds, then
turn the switch OFF.
2. Open the radiator drain plug. Open the
