cPush the MODE switch to change from
ÉF to ÉC.cWhen the outside temperature is be-
tween 130ÉF (55ÉC) and 158ÉF (70ÉC),
the display shows 130ÉF (55ÉC).
cWhen the outside temperature is
lower than -40ÉF (-40ÉC) or higher
than 158ÉF (70ÉC), the display shows
only___
though it is operating. This
is not a malfunction.
cThe outside temperature sensor is
located in front of the radiator. The
sensor may be affected by road or
engine heat, wind direction and other
driving conditions. The display may
differ from the actual outside tem-
perature or the temperature dis-
played on various signs or bill-
boards.
cTemperature display will not update
unless the vehicle is moving faster
than 12 mph (20 km/h), or the ignition
switch has been OFF for 4 hours.
COMPASS DISPLAY
Push the MODE switch when the ignition
key is in the ACC or ON position. The
direction will be displayed.
Zone variation change procedure
The difference between magnetic north and
geographical north is known as variance. In
some areas, this difference can sometimes
be great enough to cause false compass
readings. Follow these instructions to set
the variance for your particular location if
this happens:
1. Establish your location on the zone map.
Refer to the illustration. Record your
zone number.
2. Push the MODE switch in for five sec-
onds until the current zone entry number
is displayed.
3. Press the MODE switch repeatedly until
the new zone entry number is displayed.
Once the desired zone number is displayed,
stop pressing the MODE switch and the
display will show compass direction within a
few seconds.

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 on all four
wheels of MUD & SNOW or ALL SEA-
SON tires. Please consult your 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. Use of tire
chains may be prohibited according 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 manufac-
turer's suggestions.Use only SAE
Class ``S'' chains.Other types may
damage your vehicle. Use chain tension-
ers when recommended by the tire chain
manufacturer to ensure a tight fit. Loose
end links of the tire chain must be se-
cured or removed to prevent the possi-
bility of whipping action damage to the
fenders or undercarriage. If possible,
avoid fully loading your vehicle when
using tire chains. In addition, drive at a
reduced speed, otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely af-
fected. Never install tire chains on a
TEMPORARY USE ONLY spare tire. 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 much 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.
c
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.

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
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
shift lever to N (Neutral). On automatic
transmission models, move the selector
lever to 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 radia-
tor should not leak water. If coolant is
leaking, or 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, engine belts or
the engine cooling fan. The engine
cooling fan 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.

Automatic transmission fluid level*
Check the level after putting the selector
lever in P with the engine idling at operating
temperature.
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.
Engine drive belts*Make sure the drive
belts are not frayed, worn, cracked or oily.
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
Exhaust systemMake sure there are no
loose 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.When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shift lever
to N (Neutral). For automatic trans-
mission models, move the selector
lever to P (Park).
cBe sure the ignition key is in the OFF
or LOCK position when performing
any parts replacement or repairs.
cNever leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
cNever connect or disconnect the bat-
tery or any transistorized compo-
nent while the ignition switch is in
the ON position.

The engine cooling system is filled at the
factory with a high-quality, year-round,
genuine NISSAN anti-freeze coolant solu-
tion. The anti-freeze solution 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 ethylene glycol
anti-freeze with the proper mixture ratio
of 50% Genuine Nissan Anti-freeze
coolant or equivalent and 50% demin-
eralized or distilled water. The use of
other types of coolant solutions may
damage the engine cooling system.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level
is below the MIN level, add coolant to the
MAX level. If the reservoir tank is empty,
check the coolant level in the radiatorwhen
the engine 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 tank up to the MAX level.
