.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.
. Adjust your speed and driving to the road
conditions.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system automa-
tically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is off.
When the VDC switch is used to turn off the
system, the VDC system still operates to
prevent one drive wheel from slipping by
transferring power to a non slipping drive
wheel. The VDC warning light
flashes if
this occurs. All other VDC functions are off,
and the VDC warning light
will not flash.
The VDC system is automatically reset to on
when the ignition switch is placed in the off
position then back to the on position.
When the 4L position is selected with the
4WD shift switch, the VDC system is
disabled and the VDC off indicator light
illuminates (for 4WD models).
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-18) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-21). 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.
WARNING
.
The VDC system is designed to help
improve driving stability but does not
prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed
and be especially careful when driving
and cornering on slippery surfaces
and always drive carefully.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not INFINITI recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the VDC warning light
may
illuminate. .
If brake related parts such as brake
pads, rotors and calipers are not
INFINITI recommended or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are not
INFINITI recommended or are extre-
mely deteriorated, the VDC warning
light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the VDC warning
light
may illuminate. Do not drive
on these types of roads.
. When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the VDC warning light
may
illuminate. This is not a malfunction.
Restart the engine after driving onto
a stable surface.
. If wheels or tires other than the
INFINITI recommended ones are
used, the VDC system may not oper-
ate properly and the VDC warning
light
may illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a

CAUTION
.Always connect positive (+) to posi-
tive (+) and negative (−) to body
ground (as illustrated) — not to the
battery.
. Make sure the jumper cables do not
touch moving parts in the engine
compartment and that clamps do
not contact any other metal.
6. Start the engine of the booster vehicle
and let it run for a few minutes.
7. Keep the engine speed of the booster vehicle
at about 2,000 rpm, and start
the engine of the vehicle being jump
started
.

Be sure to dispose of the cloth used to
cover the vent holes as it may be
contaminated with corrosive acid.
10. Put the battery cover on. Do not attempt to start the engine by
pushing.
CAUTION
.
Automatic transmission models can-
not be push-started or tow-started.
Attempting to do so may cause
transmission damage.
. Three way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.
. Never try to start the vehicle by
towing it; when the engine starts,
the forward surge could cause the
vehicle to collide with the tow vehi-
cle.

TOWING RECOMMENDED BY
INFINITI
Two-Wheel Drive (2WD) models
INFINITI recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed
truck as illustrated.
CAUTION
.Never tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground (forward or backward), as this may
cause serious and expensive damage
to the transmission. If it is necessary
to tow the vehicle with the front
wheels raised, always use towing
dollies under the rear wheels.
. When towing rear wheel drive models
with the front wheels on the ground
or on towing dollies: Place the igni-
tion in the ACC or ON position, and
secure the steering wheel in a
straight-ahead position with a rope
or similar device.

In case of emergency6-17

Occasionally remove loose dust from the
interior trim, plastic parts and seats using a
vacuum cleaner or soft bristled brush. Wipe
the vinyl and leather surfaces with a clean,
soft cloth dampened in mild soap solution,
then wipe clean with a dry soft cloth.
Regular care and cleaning is required in order
to maintain the appearance of the leather.
Before using any fabric protector, read the
manufacturer’s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water, to
clean the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifica-
tion sensors. This can also affect the
operation of the air bag system and
result in serious personal injury.
CAUTION
.Never use benzine, thinner, or any
similar material. .
For cleaning, use a soft cloth, dam-
pened with water. Never use a rough
cloth, alcohol, benzine, thinner or any
kind of solvent or paper towel with a
chemical cleaning agent. They will
scratch or cause discoloration to the
lens.
. Do not spray any liquid such as water
on the meter lens. Spraying liquid
may cause the system to malfunction.
. Small dirt particles can be abrasive
and damaging to the leather surfaces
and should be removed promptly. Do
not use saddle soap, car waxes,
polishes, oils, cleaning fluids, sol-
vents, detergents or ammonia-based
cleaners as they may damage the
leather’s natural finish.
. Only use fabric protectors approved
by INFINITI.
. Do not use glass or plastic cleaner on
meter or gauge lens covers. It may
damage the lens cover.
AIR FRESHENERS
Most air fresheners use a solvent that could
affect the vehicle interior. If you use an air
freshener, take the following precautions:
.Hanging-type air fresheners can cause
permanent discoloration when they con-
tact vehicle interior surfaces. Place the
air freshener in a location that allows it
to hang free and not contact an interior
surface.
. Liquid-type air fresheners typically clip
on the vents. These products can cause
immediate damage and discoloration
when spilled on interior surfaces.
Carefully read and follow the manufac-
turer’s instructions before using air fresh-
eners.

pounds or solvents to clean the wood
trim.
FLOOR MATS
WARNING
To avoid potential pedal interference
that may result in a collision, injury or
death:
.NEVER place a floor mat on top of
another floor mat in the driver front
position or install them upside down
or backwards.
. Use only genuine INFINITI floor mats
or equivalent floor mats that are
specifically designed for use in your
vehicle model and model year.
. Properly position the mats in the
floorwell using the floor mat posi-
tioning hooks. See “Floor mat instal-
lation” (P.7-7).
. Make sure the floor mat does not
interfere with pedal operation. .
Periodically check the floor mats to
make sure they are properly installed.
. After cleaning the vehicle interior,
check the floor mats to make sure
they are properly installed.
The use of genuine INFINITI floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular cleaning
and replaced if they become excessively
worn.

8-2Do-it-yourself
When performing any inspection or main-
tenance 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
.Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the
vehicle from moving. Move the shift
lever to P (Park).
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. Never connect or disconnect the
battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.
. 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.
. It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
. Always wear eye protection when-
ever you work on your vehicle.
. 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.
. Never get under the vehicle while it is
supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
. On gasoline engine models, the fuel
filter or fuel lines should be serviced
because the fuel lines are under high
pressure even when the engine is off. It is recommended you visit an
INFINITI retailer for this service.
CAUTION
.
Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
. Avoid direct contact with used en-
gine oil and coolant. Improperly dis-
posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items which
are relatively easy for an owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-34).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and could
affect your warranty coverage. If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.
