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.

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

FREEING A FROZEN DOOR LOCK To 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-FREEZE In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC), check
anti-freeze to assure proper winter protection.
For additional information, see ªEngine Cool-
ing Systemº in the ª8. Do-it-yourselfº section.
BATTERY If 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 WATER If the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-
ing the drain plug located under the radiator.
Refill before operating the vehicle. See ªEn-
gine cooling systemº in the ª8. Do-it-yourselfº
section for changing engine coolant. TIRE EQUIPMENT 1. 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, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels.
Please consult your INFINITI retailer 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. Check
local, state and provincial laws before in-
stalling studded tires.
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 according to
the chain manufacturer's suggestions. Use
of tire chains may be prohibited according
to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are in- stalled according to the chain manufactur-
er's suggestions. Use only SAE Class S
chains. Class ªSº chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class ªSº
chains are designed to meet the SAE stan-
dard minimum clearances between the tire
and the closest vehicle suspension or body
component required to accommodate the
use of a winter traction device (tire chains
or cables). The minimum clearances are
determined using the factory equipped tire
size. Other types may damage your ve-
hicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the tire
chain must be secured or removed to pre-
vent the possibility of whipping action dam-
age to the fenders or underbody. If pos-
sible, 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.
Never install tire chains on a T-type spare
tire. Do not use tire chains on dry roads.

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.

Blocking wheels Place suitable blocks at both the front and
back of the wheel diagonally opposite the flat
tire to prevent the vehicle from rolling when it is
jacked up.
WARNINGBe sure to block the wheel as the vehicle
may move and could cause personal
injury. Getting the spare tire and tools Remove jacking tools 1 and spare tire 2 from
the storage area located inside the trunk as
illustrated.

The jack should be used on level firm
ground.
2. Loosen each wheel nut one or two turns by
turning counterclockwise with the wheel nut
wrench. Do not remove the wheel nuts
until the tire is off the ground.
3. Carefully raise the vehicle until the tire
clears the ground. To lift the vehicle, se-
curely hold the jack lever and rod with both
hands as shown above. Remove the wheel
nuts, and then remove the tire.
WARNING O Never get under the vehicle while it is
supported only by the jack.
O Use only the jack provided with your
vehicle to lift the vehicle. Do not use
the jack provided with your vehicle
on other vehicles.
The jack is designed only for lifting
your vehicle during a tire change. O Use the correct jack up points; never
use any other part of the vehicle for
jack support.
O Never jack up the vehicle more than
necessary.
O Never use blocks on or under the
jack.
O Do 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.
O Do not allow passengers to stay in
the vehicle while it is on the jack. CE1092

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.
