deformation, rot or loose connections.
Underbody:
The underbody is frequently exposed to corro-
sive substances such as those used on icy roads
or to control dust. It is very important to remove
these substances, otherwise rust will form on the
floor pan, frame, fuel lines and around the ex-
haust system. At the end of winter, the under-
body should be thoroughly flushed with plain
water, being careful to clean those areas where
mud and dirt may accumulate. For additional
information, see “Cleaning exterior” in the “7.
Appearance and care” section.
Windshield washer fluid*:
Check that there is adequate fluid in the tank.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
Park 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.
Be sure the ignition key is in the OFF
or LOCK position when performing
any replacement or repair.
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 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 nec-
essary to work under the vehicle,
support it with safety stands.
Keep smoking materials, flame and
sparks away from fuel and battery.
Your 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 be-
fore working near the fan.

multiport 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
Do not work under the engine hood
while it is hot. Turn off the engine and
wait until it cools down.
Never connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion key is on.
Never leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition key is on.
Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant, and/or
other vehicle fluids can hurt the envi-ronment. Always conform to local
regulations for disposal of vehicle
fluid.
This section gives instructions regarding only
those items which are relatively easy for an
owner to perform. More involved service should
be done by your NISSAN dealer.
A genuine NISSAN Service Manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “9. Technical and con-
sumer information” section.
You should be aware that incomplete or im-
proper servicing may result in operating difficul-
ties or excessive emissions, and could affect
your warranty coverage.If in doubt about any
servicing, have it done by your NISSAN
dealer.8-6

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors, therefore additional
cooling system additives are not necessary.
CAUTION
When adding or replacing the coolant,
be sure to use only Genuine NISSAN
Long Life Anti-freeze Coolant or an
equivalent with the proper mixture ratio
of 50% anti-freeze and 50% demineral-
ized water/distilled water. The use of
other types of coolant solutions may
damage your engine cooling system.Outside tempera-

WARNING
Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator. Wait
until the engine and radiator cool
down. See “If your vehicle overheats”
in the “6. In case of emergency” sec-
tion.
The radiator is equipped with a pres-
sure cap. To prevent engine damage,
use only a genuine NISSAN radiator
cap.
CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the MIN level, add coolant to the MAX
level. If the reservoir tank is empty, check the
coolant level in the radiatorwhen the engine is
cold.If there is insufficient coolant in the radia-
tor, fill the radiator with coolant up to the filler
opening and also add it to the reservoir tank up
to the MAX level.
If the engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.

jewelry, and clothing away from any
moving parts such as fan and drive
belt.
Automatic transmission fluid is poi-
sonous and should be stored care-
fully in marked containers out of the
reach of children.
TEMPERATURE CONDITIONS FOR
CHECKINGThe fluid level should be checked using the HOT
range (L & H marks) on the dipstick at fluid
temperatures between 122 and 176°F (50 and
80°C) after the vehicle has been driven approxi-
mately 5 minutes in urban areas after the engine
is warmed up. The level can be checked at fluid
temperatures between 86 and 122°F (30 and
50°C) using the COLD range on the dipstick for
reference, after the engine is warmed up but
before driving. However, the fluid level must be
rechecked using the HOT range.
1. Park the vehicle on a level surface and set the
parking brake.
2. Start the engine and then move the selector
lever through each gear range, ending in P.
3. Check the fluid level with the engine idling.
4. Expand the spring stopper and remove the
dipstick. Wipe it clean with lint-free paper.
5. Re-insert the dipstick into the charging pipe
as far as it will go.
6. Remove the dipstick and note the reading.
If the level is on the low side of either range, add
fluid to the charging pipe.7. When inserting the dipstick, set it so that the
spring stopper presses the upper part of the
