Open or close, and adjust the air flow direction
of ventilators.

closed when the vent switch is moved to
the left.: This symbol indicates that the vents are

WARNING
The air conditioner cooling function
operates only when the engine is
running.
Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be left alone either. On
hot, sunny days, temperatures in a
closed vehicle could quickly become
high enough to cause severe or pos-
sibly fatal injuries to people or ani-
mals.
Do not use the recirculation mode for
long periods as it may cause the
interior air to become stale and the
windows to fog up.
Positioning of the heating or air con-
ditioning controls should not be
done while driving so full attention
may be given to vehicle operation.

Operating tipsKeep windows and sun roof closed while theair conditioner is in operation.
After parking in the sun, drive for two or three
minutes with the windows open to vent hot air
from the passenger compartment. Then,
close the windows. This will allow the air
conditioner to cool the interior more quickly.
The air conditioning system should be
operated for about ten minutes at least
once a month. This helps prevent dam-
age to the system due to lack of lubri-
cation.
If the coolant temperature gauge exceeds the
hot position, turn the air conditioner off. For
additional information, see “If your vehicle
overheats” in the “6. In case of emergency”
section.

If the tires other than the recom-
mended ones are used, the vehicle
dynamic control system may not op-
erate properly or the vehicle dynamic
control off indicator light may come
on.
The vehicle dynamic control system
is not a substitute for winter tires or
tire chains on a snow covered road.
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 32°F (0°C), check
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“8. Maintenance and do-it-yourself” section.BATTERYIf the battery is not fully charged during extremely
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 “Battery” in
the “8. Maintenance and do-it-yourself” section.DRAINING OF COOLANT WATERIf 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 before operating the
vehicle. See “Engine cooling system” in the “8.
Maintenance and do-it-yourself” section for
Changing Engine Coolant.
TIRE EQUIPMENT1. SUMMER tires are of a tread design to
provide superior performance on dry pave-
ment. 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, NISSAN recommends
the use of MUD & SNOW or ALL SEASON
tires on all four wheels. Please consult your
NISSAN dealer for the tire type, size, speed
rating and availability information.
2. For additional traction on icy roads, studded
tires may be used. However, some Provinces
and States prohibit their use, so, before
installing studded tires, check local, state and
provincial laws.
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 if desired. Make
sure they are of proper size for the tires on
your vehicle 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 install-
ing tire chains. When installing tire chains,
make sure they are of proper size for the tires
on your vehicle and are installed according to

12 volts. Use of an improperly rated
battery can damage your vehicle.
Whenever working on or near a bat-
tery, always wear suitable eye protec-
tors (for example, goggles or indus-
trial safety spectacles) and remove
rings, metal bands, or any other
metal jewelry. Do not lean over bat-
tery when jump starting.
Do not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
Your vehicle has an automatic en-
gine cooling fan. It could come on at
any time. Keep hands and other ob-
jects away from it.
WARNING
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.
1. Position the two vehicles to bring their bat-
teries into close proximity to each other if the
booster battery is in another vehicle.Do not
allow the two vehicles to touch.
2. Apply parking brakes. Move the shift lever toNeutral position (On automatic transmission
models, move the selector lever to P (Park)).
Switch off all unnecessary electrical systems
(light, heater, air conditioner, 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 as
illustrated.
CAUTION
Always connect positive (+) to posi-
tive (+) and negative (−) to body
ground, (for example, strut mounting
bolt, engine lift bracket, etc. — not to
the battery).
Make sure that cables do not touch
moving parts in the engine compart-
ment and that clamps do not contact
any other metal.
5. Start the engine of the other vehicle and let it
run for a few minutes.
6. Keep the engine speed of the other vehicle at
about 2,000 rpm, and start your engine in the
normal manner.

tioner temperature control to maximum hot
and 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 tem-
perature 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. Do not open the
hood until no further steam or coolant can be
seen.
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 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.
WARNING
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.
The engine cooling fan can start at
any time when the coolant tempera-
ture is high.
7. After the engine cools down, check the cool-
ant level in the reservoir tank with the engine
running. Add coolant to the reservoir tank if
necessary. Have your vehicle repaired at the
nearest NISSAN dealer.For information about towing your vehicle behind
a recreational vehicle (RV), refer to “Flat towing”
in the “9. Technical and consumer information”
section of this manual.
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 instructions are
available from your NISSAN dealer. Local ser-
vice operators are generally 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
advisable to have the service operator carefully
read the following precautions:
WARNING
Never ride in a vehicle that is being
towed.
Never get under your vehicle after it
has been lifted by a tow truck.TOWING YOUR VEHICLE
