IThe outside temperature sensor is
installed in the front of the radiator.
The display may not indicate the cor-
rect temperature due to the heat of
the road and engine depending on
the direction of the wind and driving
conditions, etc.
IUse the ªICEº indication for reference
only. Confirm the traffic information
and road conditions to drive safely.
IWhen the outside temperature is be-
tween 130ÉF (55ÉC) and 158ÉF (70ÉC),
the display shows 130ÉF (55ÉC).
IWhen the outside temperature is
lower than þ20ÉF (þ30ÉC) or higher
than 158ÉF (70ÉC), the display shows
only ª
---º though it is operating. This
is not a problem.

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
overheatsº found in the ªIn case of emergencyº
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.
If the cooling system frequently requires

dealer.
CHANGING ENGINE COOLANT
IMajor cooling system repairs should be
performed by your NISSAN dealer. The
service procedures can be found in the
appropriate NISSAN Service Manual.IImproper servicing can result in reduced
heater performance and engine overheat-
ing.
ITo avoid the danger of being scalded,
never change the coolant when the
engine is hot.
INever remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.

brakes.
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be
checked periodically e.g. each time you check
the engine oil or refuel.
Windshield washer fluid*Check that there is
adequate fluid in the tank.
Engine coolant level*Check the coolant level
when the engine is cold.
Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure
the hoses have no cracks, deformation, rot or
loose connections.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
ªMAXº and ªMINº lines on the reservoir.
Battery*Check the fluid level in each cell. It
should be between the ªMAXº and ªMINº lines.
Engine drive belts*Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*Check the level after parking
the vehicle on a level spot and turning off the
engine. (Be sure to wait a few minutes to allowthe oil to drain back into the sump.)
Power steering fluid level* and linesCheck
the level when the fluid is cold and the engine
is turned off. Check the lines for proper attach-
ment, leaks, cracks, etc.
Automatic transmission fluid level*Check
the level after putting the selector lever in ªPº
with the engine idling.
Exhaust systemMake sure there are no
loose supports, cracks or holes. If the sound of
the exhaust seems unusual or there is a smell
of exhaust fumes, immediately locate the
trouble and correct it. (See the carbon monox-
ide warning in the ªStarting and drivingº sec-
tion)
UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. See the ªAppearance and Interior
Careº section for additional information.
Fluid leaksCheck under the vehicle for fuel,
oil, water or other fluid leaks after the vehiclehas been parked for a while. Water dripping
from the air conditioner after use is normal. If
you should notice any leaks or if gasoline
fumes are evident, check for the cause and
have it corrected immediately.
