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-

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 yourself
and others rests in the hands of the
driver.
Tire type and condition of tires may also
affect braking effectiveness.
O When replacing tires, install the
specified size of tires on all four
wheels.
O When 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. When driving on slippery surfaces or suddenly
avoiding obstacles on roads, the vehicle might
swerve or slip. With the vehicle dynamics
control (VDC) system, sensors detect these
movements and control the braking and en-
gine output to help improve vehicle stability
while driving.
O When the vehicle dynamics control system
is operating, the slip indicator in the instru-
ment panel blinks.
O When only the traction control system por-
tion of the vehicle dynamics control system
is operating, the slip indicator will also blink.
O If the slip indicator blinks, the vehicle is
under slippery conditions. Be sure to drive
carefully. See ªSlip indicator lightº, and ªVe-
hicle dynamics control off indicator lightº in
the ª2. Instruments and controlsº section.
O Indicator light
If a malfunction occurs in the system, the
SLIP and indicator lights come on in
the meter panel.
As long as these warning lights are on, the
traction control function is canceled.
The VDC system uses a Brake Limited Slip
Differential (LSD) system to improve vehicle
traction. The brake LSD system works when
one of the driving wheels is spinning on aVEHICLE DYNAMICS CONTROL
(VDC) SYSTEM

slippery surface. The brake LSD system
brakes the spinning wheel which distributes
the driving power to the other drive wheel. If
the vehicle is operated with the vehicle dynam-
ics control system turned off, all VDC and TCS
functions will be turned off. The brake LSD
system and ABS will still operate with the VDC
system off. If the brake LSD system or the ABS
is activated, the slip indicator light will blink and
you may hear a clunk noise and/or feel a
pulsation in the brake pedal. This is normal.
While the VDC system is operating, you may
feel a pulsation in the brake pedal and hear a
noise or vibration from under the hood. This is
normal and indicates that the VDC system is
working properly.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in
reverse at a slow speed. 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 a malfunction.
WARNINGO The vehicle dynamics control system
is designed to help improve driving stability but does not prevent acci-
dents due to abrupt steering opera-
tion at high speeds or by careless or
dangerous driving techniques. Re-
duce vehicle speed and be especially
careful when driving and cornering
on slippery surfaces and always drive
carefully.
O If suspension parts such as shock
absorbers, struts, springs and bush-
ings are not standard equipment or
are extremely deteriorated, the ve-
hicle dynamics control off indicator
light may come on.
O When driving on extremely inclined
surfaces such as higher banked cor-
ners, the vehicle dynamics control
system may not operate properly or
the vehicle dynamics control off indi-
cator light may come on. Do not drive
on these types of roads.
O If the tires other than the recom-
mended ones are used, the vehicle
dynamics control system may not op-
erate properly or the vehicle dynam- ics control off indicator light may
come on.
O The vehicle dynamics control system
is not a substitute for winter tires or
tire chains on a snow covered road.

O The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.
O Whenever working on or near a bat-
tery, always wear suitable eye protec-
tors (for example, goggles or indus-
trial safety spectacles) and remove
rings, metal bands, or any other jew-
elry. Do not lean over the battery
when jump starting.
O Do not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
If needed Roadside Assistance is available.
Please see your Warranty Information Booklet
or Roadside Assistance I.D. Card for the toll-
free number to call (U.S.) or Warranty & Road-
side assistance information booklet (Canada).
WARNING Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.
1. If the booster battery is in another vehicle,
position the two vehicles to bring their bat-
teries into close proximity to each other.
Do not allow the two vehicles to touch. 2. Apply parking brake. Move the shift lever to
the N (Neutral) position (On automatic
transmission models, move the selector
lever to the P (Park) position). Switch off all
unnecessary electrical 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. SCE0426

In order to maintain the appearance of your
vehicle, it is important to take proper care of it.
In the following cases, please wash your ve-
hicle as soon as possible to protect the paint
surface.
O After a rainfall to prevent possible damage
from acid rain
O After driving on coastal roads
O When contaminants such as soot, bird
droppings, tree sap, metal particles or bugs
get on the paint surface
O When dust or mud builds up on the surface
Whenever possible, store or park your vehicle
inside a garage or in a covered area.
When it is necessary to park outside, park in a
shady area or protect the vehicle with a body
cover.
Be careful not to scratch the paint surface
when putting on or removing the body
cover.
WASHING Thoroughly rinse surface dirt off the vehicle
with a wet sponge and plenty of clean water.
Clean the vehicle thoroughly using a mild soap
such as Nissan Car Wash, or a general pur-
pose dishwashing liquid mixed with clean, lukewarm (never hot) water.
CAUTION O Do not use strong household soap,
strong chemical detergents, gasoline
or solvents.
O Do not wash the vehicle in direct
sunlight or while the vehicle body is
hot, as the surface may become
water-spotted.
O Avoid using tight-napped or rough
cloths, such as washing mitts. Care
must be taken when removing
caked-on dirt or other foreign sub-
stances so that the paint surface is
not scratched or damaged.
Rinse the vehicle again with plenty of clean
water.
Inside flanges, seams and folds on the doors,
hatches and hood are particularly vulnerable
to the effects of road salt. Therefore, these
areas must be regularly cleaned. Make sure
that the drain holes in the lower edge of the
door are open. Spray water under the body and in the wheel wells to loosen the dirt and
wash away road salt.
Avoid leaving water spots on the paint surface
by using a damp chamois to dry the vehicle.
WAXING Regular waxing protects the paint surface and
helps retain new vehicle appearance. Polish-
ing is recommended to remove built-up wax
residue and to avoid a weathered appearance
before re-applying wax.
If you wish to wax your vehicle, only use a wax
specified for use over clear coats, such as
Nissan Liquid or Spray Wax. Your INFINITI
retailer can assist you in choosing the proper
product.
O Wax your vehicle only after a thorough
washing. Follow the instructions supplied
with the wax.
O Do not use a wax containing any abrasives,
cutting compounds or cleaners that may
damage the vehicle finish.
O If the surface does not polish easily, use a
road tar remover and wax again.
Machine compounding or aggressive pol-
ishing on a base coat/clear coat paint finish
may dull the finish or leave swirl marks.CLEANING EXTERIOR

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

WARNINGSee your INFINITI retailer and have it
checked if the brake pedal height does
not return to normal.
Brake pad wear indicators The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it will make a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indi-
cator sound is heard.
Under some driving or climate conditions, oc-
casional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does not
affect the function or performance of the brake
system.
Proper brake inspection intervals should
be followed. For additional information, see
ªPeriodic maintenance schedulesº in the ª9.
Maintenanceº section for maintenance inter-
vals. High performance sports brake pad occasion-
ally makes squeak, squeal or other braking
noise because of its very high friction coeffi-
cient.
These occasional brake noise is normal, but if
it continues, see your INFINITI retailer.
BRAKE BOOSTER Check the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) re-
mains the same from one pedal application
to the next, continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a
little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height should
not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradu-
ally with each depression as the vacuum is
released from the booster. If the brakes do not operate properly, see your
INFINITI retailer.
