The tachometer indicates engine speed in
revolutions per minute (r/min).
CAUTION
When engine speed approaches the
red zone, shift to a higher gear. Operat-
ing the engine in the red zone may
cause serious engine damage.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 over the normal
range, stop the vehicle as soon as
safely possible. If the engine is over-
heated, continued operation of the ve-
hicle may seriously damage the engine.
See the ``In case of emergency'' section
for immediate action required.

2. Move the air control dial to the,
, or the position in between.
3. Move the fan control lever to the desired
position.
4. Push in the air conditioner switch. The
indicator light comes on.
5. Turn the temperature control dial to the
desired position.
Operating tips
IKeep windows and sunroof closed while
operating the air conditioner.
IAfter 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.
IThe air conditioning system should be
operated for about ten minutes at least
once a month, especially in winter. This
helps prevent damage to the system due
to lack of lubrication.
IIf the coolant temperature gauge ex-
ceeds the (hot) position, turn the air
conditioner off. Have your vehicle in-spected by a NISSAN dealer. See ``If
your vehicle overheats'' in the ``In case of
emergency'' section for additional infor-
mation.

Using the system, 2WD Vehicles
(2 wheel rear ABS)
Depress the brake pedal and hold it down.
With the rear anti-lock brake system, the
front wheels can still lock. If this happens,
release the brake pedal slightly and then
reapply pressure.
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 under
some conditions, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel, or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance 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 may also affect
braking effectiveness.
IWhen replacing tires, install the
specified size of tires on all four
wheels.
IWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. See
``Tire placard'' in the ``Technical and
consumer information'' section.
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 in the key hole.
Anti-freeze
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check anti-freeze (ethylene glycol base) to
assure proper winter protection. For details,
see ``Engine cooling system'' in the ``Do-it-
yourself'' section of this manual.
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 of this manual.
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
radiator and on the engine block. Refill

If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power, or
detect abnormal noise, etc., take the follow-
ing steps:
WARNING
IDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
ITo 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.
IDo 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 N (Neutral), or the au-
tomatic transmission into P (Park).
Do not stop the engine.
2.
Turn off the air conditioner (if so
equipped). Open all of the windows,
move the heater or air conditioner tem-perature 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 r/min)
until the temperature gauge indicator re-
turns 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 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 radiator
should not leak water. If coolant is leak-
ing, or the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.
WARNING
IBe careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or to get caught in, the
running fan or belts.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reser-
voir tank if necessary. Have your vehicle
repaired at an authorized NISSAN
dealer.

8. Start the engine and warm it up until it
reaches normal operating temperature.
Then race the engine two or three times
under no load. Watch the engine coolant
temperature gauge for signs of overheat-
ing.9. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up the
MAX level.10. Open and close the air release plug to

tion. Be certain to keep the floor mat away
from the pedal.
Parking brake*Check that the lever has
the proper travel and confirm that your
vehicle is held securely on a fairly steep hill
with only the parking brake applied.
Automatic transmission Park position
mechanismCheck that the lock release
button on the selector lever operates prop-
erly and smoothly. On a fairly steep hill
check that your vehicle is held securely with
the selector lever in the P position without
applying any brakes.
UNDER THE HOOD AND
VEHICLE
The maintenance items listed here should
be checked periodically (e.g., each time you
check the engine oil or refuel).
Additional information on the following
items with an ``*'' is found in the ``Do-it-
yourself operations'' section.
Windshield washer fluid*Check that there
is adequate fluid in the reservoir.
Engine coolant level*Check the coolant
level when the engine is cold.Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, de-
formation, rot or loose connections.
Brake and clutch fluid levels*Make sure
that the brake and clutch fluid level is be-
tween the MIN and MAX lines on the reser-
voir.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Engine drive belts*Make sure the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*Check the level after
parking the vehicle on a level surface with
the engine off. Wait a few minutes for the oil
to drain back into the oil pan.
Power steering fluid level* and lines
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Automatic transmission fluid level*
Check the level after putting the selector
lever in P with the engine idling at operating
temperature.
Exhaust systemMake sure there are noloose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected by an autho-
rized NISSAN dealer. See the carbon mon-
oxide warning in the ``Starting and driving''
section of this manual.
UnderbodyThe underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise rust
may form on the floor pan, frame, fuel lines
and exhaust system. At the end of winter,
the underbody should be thoroughly flushed
with plain water, in those areas where mud
and dirt may have accumulated. See the
``Appearance and care'' section of this
manual.
Fluid leaksCheck under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.
