WARNINGO Always have the doors locked while
driving. Along with the use of seat
belts, this provides greater safety in
the event of an accident by helping to
prevent persons from being thrown
from the vehicle. This also helps keep
children and others from unintention-
ally opening the doors, and will help
keep out intruders.
O Before opening any door, always look
for and avoid oncoming traffic.
O Do not leave children unattended in-
side the vehicle. They could unknow-
ingly activate switches or controls.
Unattended children could become
involved in serious accidents.

d. You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.
THREE WAY CATALYST The three way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the converter are burned at
high temperatures to help reduce pollutants.
WARNINGO The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system compo-
nents.
O Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire. CAUTION O Do not use leaded gasoline. Deposits
from leaded gasoline seriously re-
duce the three way catalyst's ability
to help reduce exhaust pollutants.
O Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over-
rich fuel flow into the three way cata-
lyst, causing it to overheat. Do not
keep driving if the engine misfires, or
if noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by an authorized
INFINITI retailer.
O Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three way catalyst.
O Do not race the engine while warming
it up.
O Do not push or tow your vehicle to
start the engine. AVOIDING COLLISION AND
ROLLOVER
WARNING Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden steer-
ing maneuvers, because these driving prac-
tices could cause you to lose control of your
vehicle. As with any vehicle, a loss of con-
trol could result in a collision with other
vehicles or objects, or cause the vehicle to
rollover, particularly if the loss of control
causes the vehicle to slide sideways. Be
attentive at all times, and avoid driving when
tired. Never drive when under the influence of
alcohol or drugs (including prescription or
over-the-counter drugs which may cause
drowsiness). Always wear your seat belt. See
ªSeat Beltsº in the ª1. Seats, restraints and
supplemental air bag systemsº section. Also
instruct your passengers to do so.

O Make sure the area around the vehicle is
clear.
O Maintenance items should be checked pe-
riodically, e.g., each time you check engine
oil.
O Check that all windows and lights are clean.
O Visually inspect tires for their appearance
and condition. Also, check tires for proper
inflation.
O Lock all doors.
O Position seat and adjust head restraints.
O Adjust inside and outside mirrors.
O Fasten seat belts and ask all passengers to
do likewise.
O Check the operation of warning lights when
key is turned to the ON (3) position. 1. Apply the parking brake.
2. Automatic transmission:
Move the selector lever to P (Park) or N
(Neutral). (P preferred.)
The starter is designed not to operate if the
selector lever is in one of the driving posi-
tions.
Manual transmission:
Move the shift lever to N (Neutral) position,
and depress the clutch pedal to the floor
while cranking the engine.
The starter is designed not to operate un-
less the clutch pedal is fully depressed.
3. Crank the engine with your foot off the
accelerator pedal by turning the ignition
key to START. Release the key when the
engine starts. If the engine starts, but fails
to run, repeat the above procedure.
O If the engine is very hard to start in ex-
tremely cold weather or when restarting,
depress the accelerator pedal a little (ap-
proximately 1/5 to the floor) and hold it then
crank the engine. Release the key and the
accelerator pedal when the engine starts.
O If the engine is very hard to start because it
is flooded, depress the accelerator pedal all the way to the floor and hold it. Crank the
engine for 5 to 6 seconds. After cranking
the engine, release the accelerator pedal.
Crank the engine with your foot off the
accelerator pedal by turning the ignition
key to START. Release the key when the
engine starts. If the engine starts, but fails
to run, repeat the above procedure.
CAUTION Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, turn the key off and wait 10
seconds before cranking again, other-
wise the starter could be damaged.
4. Warm-up
Allow the engine to idle for at least 30
seconds after starting. Drive at moderate
speed for a short distance first, especially in
cold weather.BEFORE STARTING THE ENGINE STARTING THE ENGINE

O HEADED UPHILL WITH CURB:
j 2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
O HEADED UPHILL OR DOWNHILL, NO
CURB:
j 3
Turn the wheels toward the side of the road
so the vehicle will move away from the
center of the road if it moves.
4. Turn the ignition key to the LOCK position
and remove the key. The power assisted steering is designed to
use a hydraulic pump, driven by the engine, to
assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns or at low speeds.
WARNING If the engine is not running or is turned
off while driving, the power assist for the
steering will not work. Steering will be
much harder to operate. BRAKING PRECAUTIONS The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brake
The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can stop
the vehicle by depressing the brake pedal.
However, greater foot pressure on the brake
pedal will be required to stop the vehicle and
the stopping distance will be longer.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result,
your braking distance will be longer and the
vehicle may pull to one side during braking.
To dry brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat-up the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function correctly.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This overheats the brakes, in-
creases wear on the brake linings and pads,
and reduces gas mileage.POWER STEERING BRAKE SYSTEM

WARNINGO Do not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
O To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
O Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading), or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever
to the N (Neutral) position (automatic trans-
mission to the P (Park) position).
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi- tioner temperature control to maximum hot
and fan control to high speed.
3. If engine overheating is caused by climbing
a long hill on a hot day, run the engine at a
fast idle (approximately 1,500 rpm) until the
temperature gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Wait until no
steam or coolant can be seen before pro-
ceeding.
5. Open the engine hood.
WARNING If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check if the cooling fan is running.
The radiator hoses and radiator should not
leak water.
If coolant is leaking or the cooling fan does
not run, stop the engine. WARNING O Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or to get caught in the
cooling fan, or drive belt.
O The engine cooling fan can start at
any time when the coolant tempera-
ture is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reservoir
tank if necessary. Have your vehicle re-
paired at the nearest INFINITI retailer.
If needed, Roadside Assistance is available.

FLOOR MATS The use of Genuine INFINITI floor mats can
extend the life of your vehicle carpet and make
it easier to clean the interior. No matter what
mats are used, be sure they are fitted for
your vehicle and are properly positioned in
the footwell to prevent interference with
pedal operation. Mats should be maintained
with regular cleaning and replaced if they
become excessively worn.
Floor mat positioning aid
(Driver side only) This model includes a front floor mat bracket to
act as a floor mat positioning aid. INFINITI
floor mats have been specially designed for
your vehicle model. The driver's side floor mat
has a grommet hole incorporated in it. Simply
position the mat by placing the floor mat
bracket through the floor mat grommet hole
while centering the mat in the floorpan contour.
Periodically check to make certain that the
mats are properly positioned. SEAT BELTS The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solu-
tion. Allow the belts to dry completely before
using them.
WARNING Do not allow wet belts to roll up in the
retractor. NEVER use bleach, dye, or
chemical solvents since these may se-
verely weaken the seat belt webbing. SAI0012

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.
