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
IPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
Neutral. For an automatic transmis-
sion, move the selector lever to the P
(Park) position.
IBe sure the ignition key is in the OFF
or LOCK position when performing
any replacement or repair.
IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving fans
belts and any other moving parts.
IIt is advisable to secure or remove
any loose clothing and any jewelry,such as rings, watches, etc. before
working on your vehicle.
IAlways wear eye protection when-
ever you work on your vehicle.
IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
INever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and battery.
IYour vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without warning,
even if the ignition key is in the OFF
position and the engine is not run-
ning. To avoid injury, always discon-
nect the negative battery cable before
working near the fan.
IOn gasoline engine models with themultiport fuel injection (MFI) system,
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
IDo not work under the engine hood
while it is hot. Turn off the engine and
wait until it cools down.
INever connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
INever leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition key is on.

IKeep the battery surface clean and dry. Any
corrosion should be washed off with a
solution of baking soda and water.
IMake certain the terminal connections are
clean and securely tightened.
IIf the vehicle is not to be used for 30 days or
longer, disconnect the (Ð) negative battery
terminal cable to prevent discharge.
WARNING
IDo not expose the battery to flames
or electrical sparks. Hydrogen gas
generated by battery action is explo-
sive. Do not allow battery fluid to
contact your skin, eyes, fabrics, or
painted surfaces. After touching a
battery or battery cap, do not touch or
rub your eyes. Thoroughly wash your
hands. If the acid contacts your eyes,
skin or clothing, immediately flush
with water for at least 15 minutes and
seek medical attention.
IWhen working on or near a battery,
always wear suitable eye protection
and remove all jewelry.IBattery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after han-
dling.
IKeep the battery out of the reach of
children.
IDo not operate the vehicle if the fluid
in the battery is low. Low battery fluid
can cause a higher load on the bat-
tery which can generate heat, reduce
battery life, and in some cases lead to
an explosion.
JUMP STARTINGIf jump starting is necessary, see ªJump start-
ingº in the ª6. In case of emergencyº section. If
the engine does not start by jump starting, the
battery may have to be replaced. Contact your
NISSAN dealer.Check the fluid level in each cell. It should be
between the MAX. and MIN. lines.
If it is necessary to add fluid, add only distilled
water to bring the level to the indicator in each
filler opening.Do not overfill.
1. Remove the cell plugs using a suitable tool.
2. Add distilled water up to the MAX. level.
3. Tighten cell plugs.

ratings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires on four wheel drive
models, they must also be the same size,
brand, construction and tread pattern on all
four wheels.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
SNOW or ALL SEASON tire on all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some provinces
and states 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 CHAINSUse of tire chains is prohibited according to
location. Check the local laws before installing
tire chains. When installing tire chains, make
sure they are of proper size for the tires on
your vehicle and are installed according to the
chain manufacturer's suggestions.Use only
SAE class S chains.Other types may dam-
age your vehicle. Use chain tensioners when
recommended by the tire chain manufacturerto ensure a tight fit. Loose end links of the tire
chain must be secured or removed to prevent
the possibility of whipping action damage to
the fenders or underbody. If possible, avoid
fully loading your vehicle when using tire
chains. In addition, drive at a reduced speed.
Otherwise, your vehicle may be damaged
and/or vehicle handling and performance may
be adversely affected.
Never install tire chains on TEMPORARY USE
ONLY spare tires.
Do not use tire chains on dry roads.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains in
such conditions can cause damage to the
various mechanisms of the vehicle due to
some overstress. When driving on clear paved
roads, be sure to change to 2WD.
CHANGING WHEELS AND TIRES
Tire rotationNISSAN recommends that tires be rotated
every 7,500 miles (12,000 km). However, the
timing for tire rotation may vary according to
your driving habits and road surface condi-
tions.
See ªFlat tireº in the ª6. In case of emergencyº
section for tire replacing procedures.
