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 unit is damaged, dollies 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.

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) .
Automatic transmission fluid level*Check
the level after putting the selector lever in P with
the engine idling at operating temperature.
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.

The engine cooling system is filled at the factory
with Genuine NISSAN Long Life
Antifreeze/Coolant to provide year-round anti-
freeze and coolant protection. The anti-freeze
solution contains rust and corrosion inhibitors.
Additional engine cooling system additives are
not necessary.
WARNING
cNever remove the radiator or coolant
reservoir 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” found in the “In case
of emergency” section of this manual.
cThe radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a genuine
NISSAN radiator cap.

When adding or replacing coolant, be sure
to use only a Genuine NISSAN Long Life
Antifreeze/Coolant (green) or equivalent
with the proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled
water. The use of other types of coolant
solutions or coolant colors, such as or-
ange, may damage the engine cooling
system.
CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold.If the coolant level is below
the MIN level, add coolant to the MAX level. If the
reservoir 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 up to the MAX level.
If the cooling system frequently requires
coolant, have it checked by a NISSAN
dealer.
