FREEING A FROZEN DOOR LOCKTo prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole or use the Intelligent Key system.ANTIFREEZEIn the winter when it is anticipated that the
outside temperature will drop below 328F(0 8C) ,
check antifreeze to assure proper winter protec-
tion. For additional information, 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 additional information,
see “BATTERY” in the “8. Maintenance and do-
it-yourself” section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “ENGINE COOLING
SYSTEM” in the “8. Maintenance and do-it-
yourself” section.
TIRE EQUIPMENTSUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. 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.
Consult a NISSAN dealer for the tire type, size,
speed rating and availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow
tires.
Tire chains may be used. For details, see “TIRE
CHAINS” in the “8. Maintenance and do-it-
yourself” section of this manual.SPECIAL WINTER EQUIPMENTIt is recommended that the following items be
carried in the vehicle during winter:
. A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades. .
A sturdy, flat board to be placed under the
jack to give it firm support.
. A shovel to dig the vehicle out of snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
.Wet ice (32 8F, 0 8C and freezing rain) ,
very cold snow or ice can be slick
and very hard to drive on. The
vehicle will have much less traction
or “grip” under these conditions. Try
to avoid driving on wet ice until the
road is salted or sanded.
. Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels
will lose even more traction.
. Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
. Allow greater following distances
on slippery roads.

protectors (for example, goggles or
industrial safetyspectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
battery 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
objects away from it.

WARNING
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause
personal injury.
1. If the booster battery is in another vehicle*A
, position the two vehicles (
*A
and
*B)
to bring their batteries into close proximity to
each other.
Do not allow the two vehicles to touch.
2. Apply parking brake. Move the selector lever to the P (Park) position (Automatic transmis- sion models) . Move the shift lever to the N
(Neutral) position (Manual transmission
models) . Switch off all unnecessary elec-
trical systems (light, heater, air conditioner,
etc.) .
3. Remove vent caps on the battery (if so equipped) . Cover the battery with a firmly
wrung out moist cloth
*C
to reduce
explosion hazard.

CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle
fire.
. To avoid the danger of being
scalded, 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.
. Do not open the hood if steam is
coming out.
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:
1. Move the vehicle safely off the road, apply the parking brake and move the selector
lever to the P (Park) position (Automatic
transmission models) . Move the shift lever to
the N (Neutral) position (Manual transmis-
sion models) .
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air conditioner 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
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. (If steam or
coolant is escaping, turn off the engine.)
Do not open the hood further until no 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 if the cooling fan is running. The radiator hoses and radiator should not
leak water. If coolant is leaking 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 get caught in, engine belts or
the engine cooling fan. The engine
cooling fan can start at any time.
7. After the engine cools down, check the coolant level in the reservoir with the engine
running. Add coolant to the reservoir if
necessary. Have your vehicle repaired at
the nearest NISSAN dealer.

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to yourself or
damage to the vehicle. The following are general
precautions which should be closely observed.
WARNING
.Park the vehicle on a level surface,
apply the parking brake securely
and block the wheels to prevent
the vehicle from moving. For man-
ual transmission models, move the
shift lever to N (Neutral) . For auto-
matic transmission models, move
the selector lever to P (Park) .
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. Never connect or disconnect the
battery or any transistorized com-
ponent while the ignition switch is
in the ON position.
. Never leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
. If you must work with the engine running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
. It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
. Always wear eye protection when-
ever you work on your vehicle.
. If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
. Never get under the vehicle while it
is supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always
disconnect the negative battery cable before working near the fan.
. The fuel filter or fuel lines should be
serviced by a NISSAN dealer be-
cause the fuel lines are under high
pressure even when the engine is
off.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used en-
gine oil and coolant. Improperly
disposed engine oil, coolant, and/
or other vehicle fluids can damage
the environment. Always conform to
local regulations for disposal of
vehicle fluid.
This “8. Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The antifreeze solution contains
rust and corrosion inhibitors, therefore additional
cooling system additives are not necessary.
WARNING
.Never remove the radiator cap when
the engine is hot. Wait until the
engine and radiator cool down.
Serious burns could be caused by
high pressure fluid escaping from
the radiator. See precautions in “IF
YOUR VEHICLE OVERHEATS” in the
“6. In case of emergency” section of
this manual.
. The radiator is equipped with a
pressure type radiator cap. To pre-
vent engine damage, use only a
genuine NISSAN radiator cap.
CAUTION
When adding or replacing coolant, be
sure to use only a Genuine NISSAN
Long Life Antifreeze/Coolant or equiva-
lent with the proper mixture ratio of
50% antifreeze and 50% demineralized or distilled water. The use of other
types of coolant solutions may damage
the engine cooling system.

CHECKING ENGINE COOLANT LEVELCheck the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
MIN
*2, open the reservoir cap and add
coolant up to the MAX
*1
level. If the reservoir
is empty, check the coolant level in the radiator
when 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 up to the MAX level
*1.
Tighten the cap securely after adding engine
coolant.
If the cooling system requires coolant
frequently, have it checked by a NISSAN
dealer.
