CAUTION
OAutomatic transmission models can-
not be push or tow started. This may
cause transmission or other vehicle
damage.
ONever try to start the vehicle by tow-
ing it. When the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle.If your vehicle is overheating (indicated by
an extremely high temperature gauge read-
ing), or if you feel a lack of engine power, or
detect abnormal noise, etc., take the follow-
ing steps:
WARNING
ODo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
OTo 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.
ODo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road,
apply the parking brake and move the
gearshift lever to N (Neutral), or the au-
tomatic transmission into P (Park).
Do not stop the engine.
2. Turn off the air conditioner (if so
equipped). Open all of the windows,
move the heater or air conditioner tem-perature control to maximum hot and fan
control to high speed.
3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 r/min)
until the temperature gauge indicator re-
turns to normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. Wait until
no steam or coolant can be seen before
proceeding.
5. Open the hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. 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 leak-
ing, or the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.

cooling fan can start at any time when
the coolant temperature is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reser-
voir tank if necessary. Have your vehicle
repaired at an authorized NISSAN
dealer.When towing your vehicle, all State (Provin-
cial in Canada) and local regulations for tow-
ing must be followed. Incorrect towing equip-
ment could damage your vehicle. Towing
instructions are available from an authorized
NISSAN dealer. Local service operators are

Your new NISSAN has been designed to
have minimum maintenance requirements
with longer service intervals to save you
both time and money. However, some day-
to-day and regular maintenance is essential
to maintain your NISSAN's good mechani-
cal condition, as well as its emission and
engine performance.
It is the owner's responsibility to make sure
that the scheduled maintenance, as well as
general maintenance, is performed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
proper maintenance. You are a vital link in
the maintenance chain.
Scheduled maintenance
For your convenience, both required and
optional scheduled maintenance items are
described and listed in your ``NISSAN Ser-
vice and Maintenance Guide.'' You must
refer to that guide to ensure that necessary
maintenance is performed on your NISSAN
at regular intervals.
General maintenance
General maintenance includes those items
which should be checked during normalday-to-day operation of the vehicle. They
are essential if your vehicle is to continue to
operate properly. It is your responsibility to
perform these maintenance procedures
regularly as prescribed.
Performing general maintenance checks re-
quires minimal mechanical skill and only a
few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, an authorized NISSAN dealer.
Where to go for service
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and tuned by an autho-
rized NISSAN dealer.
NISSAN technicians are well-trained spe-
cialists who and are kept up-to-date with the
latest service information through technical
bulletins, service tips, and in-dealership
training programs. They are completely
qualified to work on NISSAN vehicles
beforethey work on your vehicle, rather
than after they have worked on it.
You can be confident that an authorized
NISSAN dealer's service department per-forms the best job to meet the maintenance
requirements on your vehicle Ð in a reliable
and economic way.
