downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result
in loss of vehicle control.IWhile driving on a slippery surface,
be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.
IIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.ANTI-LOCK BRAKE SYSTEM (ABS)
(if so equipped)The anti-lock brake system controls the brakes
at each wheel so the wheels will not lock when
braking abruptly or when braking on slippery
surfaces. The system detects the rotation
speed at each wheel and varies the brake fluid
pressure to prevent each wheel from locking
and sliding. By preventing wheel lockup, the
system helps the driver maintain steering con-
trol and helps to minimize swerving and spin-ning on slippery surfaces.
Using the systemDepress the brake pedal and hold it down.Do not pump the brake pedal. Doing so
may result in increased stopping
distances.Normal operationThe anti-lock brake system will not operate at
speeds below 3 to 6 MPH (5 to 10 km/h) to
completely stop the vehicle. (The speeds will
vary according to road conditions.) When the
anti-lock system senses that one or more
wheels are close to locking up, the actuator
(under the hood) rapidly applies and releases
hydraulic pressure (like pumping the brakes
very quickly). While the actuator is working,
you may feel a pulsation in the brake pedal
and hear a noise or vibration from the actuator
under the hood. This is normal and indicates
that the anti-lock system is working properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.
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
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.

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 as
specified on the tire placard. See ªVe-hicle identificationº in the ª10. Tech-
nical and consumer informationº sec-
tion for tire placard location.
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 additional infor-
mation, see ªEngine Cooling Systemº in the ª8.
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 additional
information, see ªBatteryº in the ª8. 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 inCOLD WEATHER DRIVING

These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while
actually on the ice, and avoid any
sudden steering maneuvers.
IDo not use cruise control on slippery
roads.
ISnow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)An engine block heater to assist extreme cold
temperature starting is available through your
NISSAN dealer.Do not use your heater with an un-
grounded electrical system or two-
pronged (cheater) adapters. You can be
injured by an electrical shock if you use

INever jack up the vehicle more than
necessary.
INever use blocks on or under the
jack.
IDo not start or run engine while ve-
hicle is on the jack, as it may cause
the vehicle to move. This is especially
true for vehicles with limited slid dif-
ferential carriers.
IDo not allow passengers to stay in
the vehicle while it is on the jack.
Installing the spare tire1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the wheel on and tighten the
wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel
nuts alternately and evenly until they are
tight.
4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence as illustrated.
IIncorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
IDo not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.As soon as possible tighten the wheel nuts
to the specified torque with a torque
wrench.

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.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
N (Neutral) position. For an automatic
transmission, move the selector lever
to P (Park) position.
IBe sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
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.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 remove necktie 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.
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 the bat-
tery.
IOn gasoline engine models with the
Multiport Fuel Injection (MFI) System,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer becausethe fuel lines are under high pressure
even when the engine is off.
IDo not work under the hood while the
engine 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. Improperly disposed motor oil
and/or other vehicle fluids can hurt
the environment. Always conform to
local regulations for disposal of ve-
hicle fluid.This ª8. Do-it-yourselfº section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
