cWhenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
cDo not attempt to jump start a frozen
battery. It could explode and cause se-
rious injury.
cYour vehicle has an automatic engine
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,
position the two vehicles to bring their bat-
teries near each other.
Do not allow the two vehicles to touch.2. Apply the parking brake. Move the shift lever
to N (Neutral) (manual transmission) or to P
(Park) (automatic transmission) . Switch off
all unnecessary electrical systems (lights,
heater, air conditioner, etc.) .
3. Remove vent caps on the battery (if so
equipped) . Cover the battery with an old
cloth to reduce explosion hazard.
4. Connect jumper cables in the sequence il-
lustrated (
sA,sB,sC,sD).

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.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause a ve-
hicle 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.
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever 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.) Wait
until no steam or coolant can be seen before
proceeding.
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 when the coolant
temperature is high.6. After the engine cools down, check the cool-
ant level in the reservoir tank with the engine
running. Add coolant to the reservoir tank if
necessary. Have your vehicle repaired at a
NISSAN dealer.

Wheel nuts*When checking the tires, make
sure no wheel nuts are missing, and check for any
loose wheel nuts. Tighten if necessary.
Tire rotation*Tires should be rotated every
7,500 miles (12,000 km) .
Wheel alignment and balanceIf the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for wheel
alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
cFor additional information regarding tires, refer
to “Important Tire Safety Information” (US) or
“Tire Safety Information” (Canada) in the War-
ranty Information Booklet .
WindshieldClean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
Windshield wiper blades*Check for cracks or
wear if they do not wipe properly.
Doors and hoodCheck that the doors and
hood operate properly. Also ensure that all
latches lock securely. Lubricate hinges, latches,latch pins, rollers and links as necessary. Make
sure that the secondary latch keeps the hood
from opening when the primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights*Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the ve-
hicle, etc.
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.
Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.SeatsCheck seat position controls such as seat
adjusters, seatback recliner, etc. to ensure they
operate smoothly and all latches lock securely in
every position. Check that the head restraints
move up and down smoothly and the locks (if so
equipped) hold securely in all latched positions.
Seat beltsCheck that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt web-
bing for cuts, fraying, wear or damage.
Accelerator pedalCheck the pedal for smooth
operation and make sure the pedal does not bind
or require uneven effort. Keep the floor mat away
from the pedal.
Clutch pedal*Make sure the pedal operates
smoothly and check that it has the proper free
travel.
BrakesCheck that the brakes do not pull the
vehicle to one side when applied.
Brake pedal and booster*Check the pedal for
smooth operation and make sure it has the proper
distance under it when depressed fully. Check
the brake booster function. Be certain to keep the
floor mat away from the pedal.

CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by a NISSAN dealer. The service proce-
dures can be found in the NISSAN Service
Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
cTo avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
cNever remove the radiator cap when the
engine is hot. Serious burns could be
caused by high pressure fluid escaping
from the radiator.
cAvoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
cKeep coolant out of the reach of chil-
dren and pets.Engine coolant must be disposed of prop-
erly. Check your local regulations.
