Operating tips
IKeep windows and sun roof closed while
the air conditioner is in operation.
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 willallow 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.
IIf the coolant temperature gauge exceeds
the ªHOTº position, turn the air conditioner
off. See ªIf your vehicle overheats ºin the ªIn
case of emergencyº section for additional
information.
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.

sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
ªTire placardº in the Owner's Manual
index.Freeing a frozen door lock
To 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-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 ªEn-
gine Cooling Systemº in the ªDo-it-yourself
operationsº section.
Battery
If 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 ªDo-it-yourself operationsº sec-
tion.
Draining of coolant water
If 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. For details, see ªChangingEngine Coolantº in the ªDo- it-yourself opera-
tionsº section.
Tire equipment
1. The 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 rec-
ommends the use on all four wheels of
MUD & SNOW or ALL SEASON tires.
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 Prov-
inces 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. Snow 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

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:
To avoid the danger of being burned,
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.
1. Move the vehicle safely off the road, apply
the parking brake and move the gearshift
lever to the neutral position (automatic
transmission to ªPº).
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 ªmaximum
hotº and fan control to ªhigh speedº.
3. 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.4. Open the engine hood.
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. 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.
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.
IBe careful not to allow your hands,
hair or clothing to come into contact
with, or to get caught in, the running
fan or belts.
IIf coolant is leaking, the cooling fan
belt is missing or loose or the cooling
fan does not run, stop the engine.
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.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution (anti-freeze/water mix-
ture ratio: 50/50) which will ensure protection
against freezing down to þ30ÉF (þ35ÉC). The
anti-freeze solution contains rust and corro-
sion 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 50% soft water.

The use of other types of coolant solutions
may damage your cooling system.
The radiator is equipped with a pressure cap.
Use a NISSAN genuine cap or its equivalent
when replacement is required.
Never remove the radiator cap when theengine 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 precautions in ªIf your vehicle

section.
CHECKING COOLANT LEVEL
With coolant reservoir
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the ªMINº level, add coolant to the
ªMAXº 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 ªMAXº level.
