Parking brake indicator:
When the ignition key is in the ON position, the
light comes on when the parking brake is
applied.
Low brake fluid warning light:
The light warns of a low brake fluid level. If the
light comes on while the engine is running with
the parking brake not applied, stop the vehicle
and perform the following:
1. Check the brake fluid level. Add brake fluid
as necessary. See ªBrake fluidº in the ª8.
Do-it-yourselfº section.
WARNINGO Your brake system may not be work-
ing properly if the warning light is on.
Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for re-
pairs. Otherwise, have your vehicle
towed because driving it could be
dangerous.
O Pressing the brake pedal with the
engine stopped and/or low brake fluid level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as greater pedal
travel.
O If the brake fluid level is below the
MIN mark on the brake fluid reservoir,
do not drive until the brake system
has been checked at an INFINITI re-
tailer.
2. If the brake fluid level is correct, have the
warning system checked by an INFINITI
retailer.
ABS component warning light:
The electronic component of ABS does not
work properly, if the light comes on together
with the anti-lock brake warning light when the
brake fluid is correct and the parking brake is
released. Have the system checked by an
INFINITI retailer. Drive vehicle at speeds and
avoid abrupt braking.
Charge warning light If the light comes on while the engine is
running, it may indicate that the charging sys-
tem is not functioning properly. Turn the en-
gine off and check the alternator belt. If the belt is loose, broken, missing or if the light remains
on, see your INFINITI retailer immediately.
CAUTION Do not continue driving if the belt is
loose, broken or missing.
Door open warning light This light comes on when any of the doors are
not closed securely while the ignition key is
ON.
Engine oil pressure warning
light This light warns of low engine oil pressure. If
the light flickers or comes on during normal
driving, pull off the road in a safe area, stop the
engine immediately and call an INFINITI re-
tailer or other authorized repair shop.
The engine oil pressure warning light is not
designed to indicate a low oil level. Use the
dipstick to check the oil level. See ªEngine
oilº in the ª8. Do-it-yourselfº section.

To help save the brakes and to prevent the
brakes from overheating, reduce speed and
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.
WARNINGO While 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.
O If 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) 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 system Depress the brake pedal and hold it down.
WARNING Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Normal operation The 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 feature The 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 INFINITI retailer for repair at
your earliest convenience.
WARNING The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-

carried in the vehicle during winter:
O a scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
O a sturdy, flat board to be placed under the
jack to give it firm support.
O a shovel to dig the vehicle out of snow-
drifts.
O extra window washer fluid to refill the res-
ervoir tank.
DRIVING ON SNOW OR ICE
WARNINGO Wet ice (32ÉF, 0ÉC and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have a lot less traction or grip under
these conditions. Try to avoid driving
on wet ice until the road is salted or
sanded.
O Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels will lose even more traction.
O Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
O Allow greater following distances on
slippery roads.
O Watch for slippery spots (glare ice).
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.
O Do not use cruise control on slippery
roads.
O Snow 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
INFINITI retailer. WARNING 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
an ungrounded connection.

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.
WARNINGO 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
N (Neutral) position. For an automatic
transmission, move the selector lever
to P (Park) position.
O Be sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
O 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.
O It is advised to secure or remove any loose clothing and any jewelry, such
as rings, watches, etc. before work-
ing on your vehicle.
O Always wear eye protection when-
ever you work on your vehicle.
O 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.
O 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.
O Keep smoking materials, flame and
sparks away from fuel and the bat-
tery.
O On gasoline engine models with the
Multiport Fuel Injection (MFI) System,
the fuel filter or fuel lines should be
serviced by an INFINITI retailer be-
cause the fuel lines are under high
pressure even when the engine is off. CAUTION O Do not work under the hood while the
engine is hot. Turn off the engine and
wait until it cools down.
O Never connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
O Never leave any engine or automatic
transmission related component har-
ness connector disconnected while
the ignition key is on.
O 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.

BRAKE FLUID Check the fluid level in the reservoir. If the fluid
is below the MIN line or the brake warning light
comes on, add DOT 3 fluid up to the MAX line.
If fluid must be added frequently, the system
should be thoroughly checked by your
INFINITI retailer.
WARNINGUse only new fluid. Old, inferior, or con-
taminated fluid may damage the brake system. Do not add synthetic brake
fluid. The use of improper fluids can
damage the brake system and affect the
vehicle's stopping ability.
CAUTION Do not spill the fluid on painted sur-
faces. This will damage the paint. If fluid
is spilled, wash with water.
CLUTCH FLUID Check the fluid level in the reservoir. If the fluid
level is below the MIN. line, add Genuine
Nissan Brake Fluid or equivalent DOT 3 fluid
up to the MAX. line.
