ENGINE BLOCK HEATER (if so
equipped)
WARNING
cDo not use your engine block heater
with an ungrounded electrical system
or a 2-pronged adapter. You can be se-
riously injured by an electrical shock if
you use an ungrounded connection.
cDisconnect and properly store the en-
gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury.
cUse a heavy-duty 3-wire, 3-pronged ex-
tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the
proper extension cord or a grounded
outlet can result in a fire or electrical
shock and cause serious personal
injury.
Engine block heaters are available through
NISSAN dealers to assist in cold temperature
starting. The engine block heater should be used
when the outside temperature is 20° F (-7° C) or
lower.To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engine block
heater cord.
3. Plug the engine block heater cord into a
grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded 110-
volt AC (VAC) outlet.
5. The engine block heater must be plugged in
for at least2-4hours, depending on outside
temperatures, to properly warm the engine
coolant. Use an appropriate timer to turn the
engine block heater on.
6. Before starting the engine, unplug and prop-
erly store the cord to keep it away from
moving parts.
Starting and driving5-39

CAUTION
cDo not push start this vehicle. The
three-way catalyst may be damaged.
cAutomatic transmission models cannot
be push-started or tow-started. At-
tempting to do so may cause transmis-
sion damage.
cFor manual transmission models, never
try to start the vehicle by towing it.
When the engine starts, the forward
surge could cause the vehicle to collide
with the tow vehicle.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
cTo 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.
cDo not open the hood if steam is com-
ing 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 shift selector
to N (Neutral) (manual transmission) or to P
(Park) (automatic transmission) .
Do not stop the engine.
2. Turn off the air conditioner (if so equipped) .
Open all the windows, move the heater or air
conditioner temperature control to maximum
hot and fan control to high speed.3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. 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 water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
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.
PUSH STARTING IF YOUR VEHICLE OVERHEATS
In case of emergency6-11

6. After the engine cools down, check the cool-
ant level in the engine coolant reservoir tank
with the engine running. Add coolant to the
engine coolant reservoir tank if necessary.
Have your vehicle repaired at a NISSAN
dealer.When towing your vehicle, all State (Provincial in
Canada) and local regulations for towing must be
followed. Incorrect towing equipment could dam-
age your vehicle. Towing instructions are avail-
able from a NISSAN dealer. Local service opera-
tors 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
cNever ride in a vehicle that is being
towed.
cNever get under your vehicle after it has
been lifted by a tow truck.
CAUTION
cWhen towing, make sure that the trans-
mission, axles, steering system and
powertrain are in working condition. If
any of these conditions apply, dollies or
a flatbed tow truck must be used.
cAlways attach safety chains before
towing.For information about towing your vehicle behind
a recreational vehicle (RV) , refer to “Flat towing”
in the “Technical and consumer information” sec-
tion of this manual.

Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimesMake sure all
warning lights and chimes are operating properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
MIN and MAX lines on the reservoir.
Engine coolant level*Check the coolant level
when the engine is cold.Engine drive belts*Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level*Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
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 have the exhaust
system inspected by a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Fluid leaksCheck under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
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 imme-
diately.
Power steering fluid level* and linesCheck
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.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.
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 from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield washer fluid*Check that there is
adequate fluid in the reservoir.
8-4Maintenance and do-it-yourself

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
cPark the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift selector to
P (Park) .
cBe sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
cIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
cIt is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
cAlways wear eye protection whenever
you work on your vehicle.cYour vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition switch is in the OFF posi-
tion and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before working
near the fan.
cIf you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
cNever get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
cKeep smoking materials, flame and
sparks away from the fuel tank and
battery.
cOn gasoline engine models, the fuel
filter or fuel lines should be serviced by
a NISSAN dealer because the fuel lines
are under high pressure even when the
engine is off.
CAUTION
cDo not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
cAvoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
cNever leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
cNever connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage.If in doubt about any servicing,
have it done by a NISSAN dealer.
