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 conditioning system should be
operated for about ten minutes at
least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cIf the engine coolant temperaturegauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. See ``If your
vehicle overheats'' in the ``In case of
emergency'' 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 in 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 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
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. Refillbefore operating the vehicle. See ``Chang-
ing Engine Coolant'' in the ``Do-it-yourself''
section of this manual.
Tire equipment
1.SUMMER tires are of a tread design to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads, NIS-
SAN 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, most
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 of proper size for the tires on yourvehicle and are installed according to the
chain manufacturer's suggestions.
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
manufacturer's suggestions.Use only
SAE Class ªSº 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 underbody. 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 affected.
Never install tire chains on T-type spare
tires. Do not use tire chains on dry roads.

cWhenever working on or near a bat-
tery, always wear suitable eye pro-
tectors (e.g., goggles or industrial
safety spectacles) and remove rings,
metal bands, or any other jewelry.
Do not lean over the battery when
jump starting.
cDo not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
cYour vehicle has an automatic en-
gine cooling fan. It could come on at
any time. Keep hands and other ob-
jects away from it.
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.
1.
If the booster battery is in another vehicle,
position the two vehicles to bring their
batteries into close proximity to each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. Move the shift
lever to N (Neutral) (on automatic trans-
mission models, move the lever to P
(Park)). Switch off all unnecessary elec-trical systems (lights, heater, air condi-
tioner, etc.).
3. Remove vent caps on the battery (if so
equipped). Cover the battery with an old
cloth to reduce explosion hazard.
4. Connect jumper cables in the sequence
illustrated.
CAUTION
cAlways connect positive (+) to posi-
tive (+) and negative (þ) to body
ground (e.g., strut mounting bolt,
etc.Ðnot to the battery).

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
shift lever to N (Neutral) (manual trans-
mission) 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 maximumhot 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 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 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.

CAUTION
c
Never tow an automatic transmission
model with the rear wheels raised
(with the front wheels on the ground)
as this may cause serious and expen-
sive damage to the transmission. If it
is necessary to tow the vehicle with
the rear wheels raised, always use a
towing dolly under the front wheels.
cIf you have to tow an automatic trans-
mission model with four wheels on
the ground, observe the following re-
stricted towing speeds and distances:
cSpeed: Below 30 MPH (50 km/h)
cDistance: Less than 40 miles (65
km)
VEHICLE RECOVERY (freeing a
stuck vehicle)
cTow chains or cables must be attached
only to the main structual members of the
vehicle.
cPulling devices should be routed so they
do not touch any part of the suspension,
steering, brake or cooling systems.
cAlways pull the cable straight out from
the front or rear of the vehicle. Never pull
the vehicle at an angle.
cPulling devices such as ropes or canvas
straps are not recommended for use in
vehicle towing or recovery.
cStand clear of a stuck vehicle.
WARNING
Do not spin your tires at high speed. This
could cause them to explode and result
in serious injury. Parts of your vehicle
could also overheat and be damaged.
