WARNINGThe RAS system, although a sophisticated
device, cannot prevent accidents resulting
from careless or dangerous driving tech-
niques. Ultimately the responsibility for
safety of self and others rests in the hands of
the driver. Therefore only through attentive
and careful driving methods can the RAS
system be fully appreciated and safety as-
sured. 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 antifreeze to assure proper winter
protection. For additional information, see
ªEngine cooling systemº in the ª8. Mainte-
nance and do-it-yourselfº section.
BATTERY If the battery is not fully charged during
extremely 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. Maintenance and do-it-yourselfº
section.
DRAINING OF COOLANT WATER If the vehicle is to be left outside without
antifreeze, drain the cooling system by
opening the drain plug located under the
radiator. Refill before operating the ve-
hicle. See ªEngine cooling systemº in the ª8. Maintenance and do-it-yourselfº sec-
tion for changing engine coolant.
TIRE EQUIPMENT 1. SUMMER tires are of a tread design to
provide superior performance on dry
pavement. However, the performance
of these tires will be substantially re-
duced 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
an INFINITI dealer for the tire type,
size, speed rating and availability in-
formation.
2. For additional traction on icy roads,
studded tires may be used. However,
some provinces and states prohibit
their use. Check local, state and pro-
vincial laws before installing studded
tires.
Skid and traction capabilities of
studded snow tires, on wet or dry sur-
faces, 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 in-COLD WEATHER DRIVING

Every new INFINITI comes with a 4 year,
unlimited mileage Roadside Assistance
plan. In the event of a roadside
emergency, Roadside Assistance Service
is available to you. Please refer to your
Warranty Booklet (U.S.) or Warranty &
Roadside assistance information booklet
(Canada) for details. Both the Warranty
Booklet and Roadside Assistance Calling
Card in your Owner's Literature Portfolio
provide the Toll-Free Number to call for
assistance. Roadside Assistance is
provided 24 hours a day, 365 days a year,
for 4 years from the date sold to give
emergency roadside help, in the event of
mechanical or nonmechanical trouble(s)
such as flat tires, out-of-gas, dead battery,
lost keys, mechanical breakdown,
accident, etc. TIRE PRESSURE MONITORING
SYSTEM (TPMS) This vehicle is equipped with the tire pres-
sure monitoring system (TPMS). It monitors
tire pressure of all tires except the spare.
When the low tire pressure warning light is
lit, or flashing continuously one or more of
your tires is significantly under-inflated. If
the vehicle is being driven with low tire
pressure, the TPMS will activate and warn
you of it by the low tire pressure warning
light. This system will activate only when
the vehicle is driven at speeds above 16
MPH (25 km/h). For more details, refer to
ªWarning/indicator lights and audible re-
mindersº in the ª2. Instruments and con-
trolsº section and ªTire pressure moni-
toring system (TPMS)º in the ª5. Starting
and drivingº section.
WARNING O If the low tire pressure warning light illu-
minates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as
soon as possible. Serious vehicle damage could occur and may lead to an
accident and could result in serious per-
sonal injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the
recommended COLD tire pressure shown
on the Tire and Loading Information label
to turn the low tire pressure warning light
OFF. If you have a flat tire, replace it with a
spare tire as soon as possible.
O When a spare tire is mounted or a wheel is
replaced, tire pressure will not be indi-
cated, the TPMS will not function and the
low tire pressure warning light will flash.
Contact your INFINITI dealer as soon as
possible for tire replacement and/or
system resetting.
O Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
O
Do not inject any tire liquid or aerosol tire
sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
CHANGING A FLAT TIRE If you have a flat tire, follow the instruc-
tions below.ROADSIDE ASSISTANCE PROGRAM FLAT TIRE

5. Securely store the flat tire and jacking
equipment in the vehicle.
6. Place the spare tire cover and the
trunk floor carpeting over the dam-
aged tire.
7. Close the trunk.
WARNINGO Always make sure that the spare tire and
jacking equipment are properly secured
after use. Such items can become dangerous projectiles in an accident or
sudden stop.
O The T-type spare tire and small size

able. Please see your Warranty Information
Booklet or Roadside Assistance I.D. Card
for the toll-free number to call (U.S.) or War-
ranty Information Booklet (Canada). To start your engine with a booster bat-
tery, the instructions and precautions
below must be followed.
WARNING O If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also dam-
age your vehicle.
O Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
O Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a corro-
sive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted area with wa-
ter.
O Keep battery out of the reach of children.SCE0384B

Inside the vehicle The maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Automatic transmission P (Park) mecha-
nism: On a fairly steep hill check that your
vehicle is held securely with the selector
lever in the P (Park) position without ap-
plying any brakes.
Brake pedal*: Check the pedal for smooth
operation and make sure it has the proper
distance under it when depressed fully.
Check the brake booster function. Be sure
to keep the floor mat away from the
pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake*: Check that the pedal/
lever has the proper travel and confirm
that your vehicle is held securely on a
fairly steep hill with only the parking
brake applied. Seats: Check seat position controls such
as seat adjusters, seatback recliner, etc.
to ensure they operate smoothly and that
all latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (For example, buckles, an-
chors, adjusters and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Steering wheel: Check for changes in the
steering conditions, such as excessive
free play, hard steering or strange noises.
Warning lights and chimes: Make sure
that all warning lights and chimes are op-
erating properly.
Windshield defroster: Check that the air
comes out of the defroster outlets prop-
erly and in sufficient quantity when oper-
ating the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak. Under the hood and the vehicle The maintenance items listed here should
be checked periodically (For example,
each time you check the engine oil or re-
fuel).
Battery*: Check the fluid level in each
cell. It should be between the MAX and
MIN lines. Vehicles operated in high tem-
peratures or under severe conditions re-
quire frequent checks of the battery fluid
level.
Brake and clutch fluid level*: Make sure
that the brake and clutch fluid levels are
between the MAX and MIN lines on the
reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no
belt is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level location
and turning off the engine. (Wait at least
10 minutes for the oil to drain back into
the oil pan.)
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or

such as rings, watches, etc. before work-
ing on your vehicle.
O Always wear eye protection whenever
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 neces-
sary to work under the vehicle, support it
with safety stands.
O Keep smoking materials, flame and
sparks away from the fuel tank and bat-
tery.
O On gasoline engine models with the Mul-
tiport Fuel Injection (MFI) System, the
fuel filter or fuel lines should be serviced
by an INFINITI dealer because the fuel
lines are under high pressure even when
the engine is off. CAUTION O Do not work under the hood while the en-
gine is hot. Turn the engine off and wait
until it cools down.
O Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
O Never leave the engine or automatic
transmission related component har-
ness connector disconnected while the
ignition switch is in the ON position.
O Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
This ª8. Maintenance and do-it-yourselfº
section gives instructions regarding only
those items which are relatively easy for
an owner to perform. A genuine INFINITI Service Manual is also
available. See ªOwner's Manual/Service
Manual order informationº in the ª9.
Technical and consumer informationº sec-
tion.
You should be aware that incomplete or
improper servicing may result in oper-
ating difficulties or excessive emissions,
and could affect your warranty coverage.
If in doubt about any servicing, have it
done by an INFINITI dealer.
