conditions are hazardous and extra care is
required while driving.
If a tire slips on rough roads for more than
10 seconds, the ABS brake warning light
may come on. Turn OFF the ignition key,
restart the engine and drive the vehicle at
speeds above 20 MPH (30 km/h). If the
warning light does not go out, have the
vehicle checked at a NISSAN dealer.Self-test featureThe anti-lock brake system consists of elec-
tronic sensors, electric pumps, and hydraulic
solenoids controlled by a computer. The com-
puter has a built-in diagnostic feature that tests
the system each time you start the engine and
move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may
hear a clunk noise and/or feel a pulsation in
the brake pedal. This is normal and is not an
indication of any malfunction. If the computer
senses any malfunction, it switches the anti-
lock brake system OFF and turns on the ABS
brake warning light in the dashboard. The
brake system will then behave normally, but
without anti-lock assistance.
If the light comes on during the self check, or
while you are driving, you should take your
vehicle to your NISSAN dealer for repair at
your earliest convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces, even with the anti-lock sys-
tem. Stopping distances may also be
longer on rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance from
the vehicle in front of you. Ultimately,
the responsibility for safety of self and
others rests in the hands of the driver.
Tire type and condition of tires may also
affect braking effectiveness.
IWhen replacing tires, install the
specified size of tires on all four
wheels.
IWhen installing a spare tire, make
sure it is the proper size and type asspecified on the tire placard. See
ªTire placardº in the ª9. Technical
and consumer informationº section
for tire placard location information.

FREEING A FROZEN DOOR LOCKTo prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into the key hole.ANTI-FREEZEIn the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC), check
anti-freeze (ethylene glycol base) to assure
proper winter protection. For details, see ªEn-
gine cooling systemº in the ª8. Maintenance
and do-it-yourselfº section.BATTERYIf the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
ªBatteryº in the ª8. Maintenance and do-it-
yourselfº section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-
ing the drain valves located under the radiator
and on the engine block. Refill before operat-
ing the vehicle. See ªEngine cooling systemº in
the ª8. Maintenance and do-it-yourselfº sectionfor Changing Engine Coolant.
TIRE EQUIPMENT1. SUMMER tires are of a tread design to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, NISSAN
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels.
Please consult your NISSAN dealer for the
tire type, size, speed rating and availability
information.
2. For additional traction on icy roads, studded
tires may be used. However, some Prov-
inces and States prohibit their use, so,
before installing studded tires, check local,
state and provincial laws.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
3. TIRE CHAINS may be used if desired.
Make sure they are of proper size for the
tires on your vehicle and are installed ac-
cording to the chain manufacturer's sug-
gestions. Use of tire chains may be prohib-
ited according to location. Check the local
laws before installing tire chains. Wheninstalling tire chains, make sure they are of
proper size for the tires on your vehicle and
are installed according to the chain manu-
facturer's suggestions.Use only SAE
Class S chains.Other types may damage
your vehicle. Use chain tensioners when
recommended by the tire chain manufac-
turer to 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 af-
fected.
Do not use the 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.
4. For four wheel drive:
If you install snow tires, they must also be
the same size, brand, construction and

to Neutral position (On automatic transmis-
sion models, move the selector lever to P
(Park)). Switch off all unnecessary electri-
cal systems (light, 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 as
illustrated.
CAUTION
IAlways connect positive (+) to posi-
tive (+) and negative (þ) to body
ground, (for example, strut mounting
bolt, engine lift bracket, etc. Ð not to
the battery).
IMake sure that cables do not touch
moving parts in the engine compart-
ment and that clamps do not contact
any other metal.
5. Start the engine of the other vehicle and let
it run for a few minutes.
6. Keep the engine speed of the other vehicleat about 2,000 rpm, and start your engine in
the normal manner.
CAUTION
Do not keep starter motor engaged for
more than 10 seconds. If the engine
does not start right away, turn the key
off and wait 3 to 4 seconds before trying
again.
7. After starting your engine, carefully discon-
nect the negative cable and then the posi-
tive cable.
8. Replace the vent caps (if so equipped). Be
sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
CAUTION
IAutomatic transmission models can-
not be push started. This may cause
transmission damage.
IThree way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.
INever 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.PUSH STARTING

See ªPrecautions when starting and drivingº in
the ª5. Starting and drivingº section for exhaust
gas (carbon monoxide).
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 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 ªCleaning
exteriorº in the ª7. Appearance and careº sec-
tion.
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 cor-
rected immediately.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.

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
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.
IAvoid 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
available. See ªOwner's Manual/Service
Manual order informationº in the ª9. Technical
and consumer informationº section.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage.If in doubt about
any servicing, have it done by your NISSAN
dealer.8-6
