ment. Then, close the windows. This will
allow the air conditioner to cool the interior
more quickly.
IThe air conditioning system should be op-
erated for about ten minutes at least once a
month. This helps prevent damage to the
system due to lack of lubrication.

exceeds the hot position, turn the air con-
ditioner off. For additional information, see
ªIf your vehicle overheatsº in the ª6. In case
of emergencyº section.
IIf the engine coolant reaches an extremely
high temperature, the air conditioning sys-
tem will automatically turn off. This may
happen for example if the engine is run at
idle for a long time on a hot day.
AIR FLOW CHARTSSee earlier in the ªHeater and air conditioner
(manual)º section for air flow charts.
The sensor on the instrument panel helps
maintain a constant temperature. Do not put
anything on or around this sensor.The air conditioning system in your NISSAN
vehicle is charged with a refrigerant designed
with the environment in mind.
This refrigerant will not harm the earth's
ozone layer.
However, special charging equipment and lu-
bricant are required when servicing your
NISSAN air conditioner. Using improper refrig-
erants or lubricants will cause severe damage
to your air conditioning system. See ªCapaci-
ties and recommended fuel/lubricantsº in the
ª10. Technical and consumer informationº sec-
tion for air conditioning system refrigerant and
lubricant recommendation.
Your NISSAN dealer will be able to service
your environmentally friendly air conditioning
system.
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper
equipment.

The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces, even with the anti-lock sys-
tem. Stopping distances 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 of tires 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. SeeªTire placardº in the ª10. Technical
and consumer informationº section
for tire placard location information.
FREEING A FROZEN DOOR LOCKTo prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into the key hole.ANTI-FREEZEIn 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 ªEn-
gine Cooling Systemº in the ª8. Do-it-yourselfº
section.BATTERYIf the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
ªBatteryº in the ª8. Do-it-yourselfº section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-
ing the drain valves located under the radiator
and on the engine block. Refill before operat-
ing the vehicle. See ªEngine cooling systemº in
the ª8. Do-it-yourselfº section for Changing
Engine Coolant.COLD WEATHER DRIVING

IAutomatic transmission models can-
not be push started. This may cause
transmission damage.
IThree way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.
INever try to start the vehicle by tow-
ing it; when the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle.
If your vehicle is overheating indicated by an
extremely high temperature gauge reading, or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps: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 radia-
tor 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 the neutral position (automatic
transmission to P (Park)).
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi-
tioner temperature control to maximum hotand fan control to high speed.
3. If engine overheating is caused by climbing
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 radiator
before opening the hood. Wait until no
steam or coolant can be seen before pro-
ceeding.
5. Open the engine hood.
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 leaking,
the cooling fan belt is missing or loose or
the cooling fan does not run, stop the
engine.

Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or to get caught in, the cooling fan,
or drive belt.7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reservoir
tank if necessary. Have your vehicle re-
paired at the nearest NISSAN dealer.When towing your vehicle, all State (Provincial
in Canada) and local regulations for towing
must be followed. Incorrect towing equipment
could damage your vehicle. Towing instruc-
tions are available from your NISSAN dealer.
Local service operators will generally be famil-
iar with the applicable laws and procedures for
towing. To assure proper towing and to pre-
vent accidental damage to your vehicle,
NISSAN recommends that you have a service
operator tow your vehicle. It is advisable to
have the service operator carefully read the
following precautions.
INever ride in a vehicle that is being
towed.
INever get under your vehicle after it
has been lifted by a tow truck.
IWhen towing, make sure that the
transmission, axles, steering system
and power train are in working condi-
tion. If any unit is damaged, dollies
must be used.
IAlways 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 solu-
tion contains rust and corrosion inhibitors,
therefore additional cooling system additives
are not necessary.When adding or replacing the coolant,
be sure to use an ethylene glycol anti-
freeze with the proper mixture ratio of
50% anti-freeze and 50% distilled water.
The use of other types of coolant solu-
tions may damage your engine cooling
system.Outside temperature

INever remove the radiator cap when
the engine is hot; serious burns
could be caused by high pressure
fluid escaping from the radiator. Wait
until the engine and radiator cool
down. Serious burns could be caused
by high pressure fluid escaping from
the radiator. See ªIf your vehicle over-
heatsº in the ª6. In case of emer-
gencyº section.
IThe radiator is equipped with a pres-
sure cap. Use only a genuine cap as a
replacement.
CHECKING ENGINE COOLANT
LEVELCheck 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.
