5-32Starting and driving
.Watch for slippery spots (glare ice) .
These may appear on an otherwise
clear road in shaded areas. If a
patch of ice is seen ahead, brake
before reaching it. Try not to brake
while on the ice, and avoid any
sudden steering maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist with
cold temperature starting.
The engine block heater should be used when
the outside temperature is 208F( −78C) 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 least 2 - 4 hours, 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 properly store the cord to keep it away from
moving parts.
WARNING
.Do not use your engine block heater
with an ungrounded electrical sys-
tem or a 2-pronged adapter. You can
be seriously injured by an electrical
shock if you use an ungrounded
connection.
. Disconnect and properly store the
engine block heater cord before
starting the engine. Damage to the
cord could result in an electrical
shock and can cause serious injury.
. Use a heavy-duty 3-wire, 3-pronged
extension cord rated for at least
10A. Plug the extension cord into a Ground Fault Interrupt (GFI) pro-
tected, 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.

2. Turn off the air conditioner. Open all thewindows, 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.

Windshield defroster:Check that the air
comes out of the defroster outlets properly and
in sufficient quantity when operating the heater
or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and that
the wipers do not streak.
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.
Vehicles operated in high temperatures or under
severe condition require frequent checks of the
battery fluid level.
Brake and clutch fluid levels*: Make sure
that the brake and clutch fluid levels are
between the MAX and MIN lines on the
reservoirs.
Engine coolant level*: Check the coolant level
when the engine is cold.
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. Wait more than 15 minutes for the oil to
drain back into the oil pan. Exhaust system:
Make 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
“Precautions when starting and driving” (P.5-2)
for exhaust gas (carbon monoxide) .)
Fluid leaks: Check 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
immediately.
Power steering fluid level* and lines: Check
the level with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check 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.
Underbody: The 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 thoroughly flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, see “Cleaning
exterior” (P.7-2).
Windshield washer fluid*:
Check that there is
adequate fluid in the reservoir.
Maintenance and do-it-yourself8-5

8-6Maintenance and do-it-yourself
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.
A genuine NISSAN Service Manual is also
available. (See “Owner’s Manual/Service Man-
ual order information” (P.9-24).)

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round anti-freeze
and coolant protection. The antifreeze solution
contains rust and corrosion inhibitors. Additional
engine cooling system additives are not neces-
sary.
WARNING
.Never remove the radiator or cool-
ant 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” (P.6-16) 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
.Never use any cooling system ad-
ditives such as radiator sealer. Ad-
ditives may clog the cooling system
and cause damage to the engine,
transmission and/or cooling sys-
tem.
. When adding or replacing coolant,
be sure to use only Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) or equivalent. Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) is pre-diluted to provide
antifreeze protection to −348 F
(−378C) . If additional freeze protec-
tion is needed due to weather where
you operate your vehicle, add Gen-
uine NISSAN Long Life Antifreeze/
Coolant (blue) concentrate follow-
ing the directions on the container.
If an equivalent coolant other than
Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s
instructions to maintain minimum
antifreeze protection to −348 F
(−378C) . The use of other types of
coolant solutions other than Genu- ine NISSAN Long Life Antifreeze/
Coolant (blue) or equivalent may
damage the engine cooling system.
. The life expectancy of the factory-fill
coolant is 105,000 miles (168,000
km) or 7 years. Mixing any other
type of coolant other than Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) , including Genuine
NISSAN Long Life Antifreeze/Cool-
ant (green) , or the use of non-
distilled water will reduce the life
expectancy of the factory-fill cool-
ant. Refer to the NISSAN Service
and Maintenance Guide for more
details.

CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir when
the engine is running and after it reaches
normal operating temperature. If the coolant
level is below the MIN level
*2, add coolant up
to the MAX level
*1. 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 radiator filler cap above the
radiator upper hose opening and also add it to
the reservoir up to the MAX level
*1. Put on the
filler cap above the radiator upper hose and with
the reservoir cap open, start the engine. Run the
engine until it reaches normal operating tem- perature. Add coolant 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.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by a NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
. To avoid the danger of being
scalded, never change the coolant
when the engine is hot.
. Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
. Avoid direct skin contact with used
coolant. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible. .
Keep coolant out of reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.

cally. Add window washer fluid when the low
window washer fluid warning light comes on.
To fill the window washer fluid reservoir, lift the
cap off the reservoir tank and pour the window
washer fluid into the tank opening.
Add a washer solvent to the water for better
cleaning. In the winter season, add a windshield
washer antifreeze. Follow the manufacturer’s
instructions for the mixture ratio.
Refill the reservoir more frequently when driving
conditions require an increased amount of
window washer fluid.
Recommended fluid is Genuine NISSAN Wind- shield Washer Concentrate Cleaner & Anti-
freeze or equivalent.
CAUTION
.
Do not substitute engine anti-freeze
coolant for window washer solution.
This may result in damage to the
paint.
. Do not fill the window washer
reservoir tank with washer fluid
concentrates at full strength. Some
methyl alcohol based washer fluid
concentrates may permanently stain
the grille if spilled while filling the
window washer reservoir tank.
. Pre-mix washer fluid concentrates
