Operating tipsIKeep 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 will
allow the air conditioner to cool the interior
more quickly.
IThe 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 lubrica-
tion.
IIf the coolant temperature gauge exceeds
the hot position, turn the air conditioner off.
For additional information, see ªIf your ve-
hicle overheatsº in the ª6. In case of emer-
gencyº section.AIR FLOW CHARTSThe following charts show the button and dial
positions formaximum and quickheating,

: Air flow mainly from foot outlets.: Air flow from defroster and foot outlets.
To turn the system offPush the OFF button.OPERATING TIPSIWhen the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for 0
to 126 seconds. This is not a malfunction.
After the coolant temperature warms up, air
flow from the foot outlets will operate nor-
mally.
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 equip-
ment.

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.
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 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. TIRE CHAINS may be used if desired.
Make sure they are of proper size for the
tires on your vehicle and are installed ac-
cording to the chain manufacturer's sug-
gestions. Use of tire chains may be prohib-
ited according to location. Check the local
laws before installing tire chains. When
installing tire chains, make sure they are ofproper size for the tires on your vehicle and
are installed according to the chain manu-
facturer's suggestions.Use only SAE
Class S chains.Other types may damage
your vehicle. Use chain tensioners when
recommended by the tire chain manufac-
turer to ensure a tight fit. Loose end links of
the tire chain must be secured or removed
to prevent the possibility 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 af-
fected.
Do not use the chains on dry roads.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains
in such conditions can cause damage to the
various mechanisms of the vehicle due to
some overstress. When driving on clear
paved roads, be sure to change to 2WD.
4. For four wheel drive:
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.

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.

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 Genuine Nissan Anti-
Freeze Coolant or equivalent with the
proper mixture ratio of 50% anti-freeze
and 50% demineralized water/distilled
water. The use of other types of coolant
solutions 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.
