FUEL-FILLER CAP
WARNING
. Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or ser-
iously injured if it is misused or
mishandled. Always stop engine and
do not smoke or allow open flames or
sparks near the vehicle when refuel-
ing.
. Do not attempt to top off the fuel
tank after the fuel pump nozzle shuts
off automatically. Continued refuel-
ing may cause fuel overflow, resulting
in fuel spray and possibly a fire.
. Use only an original equipment type
fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious malfunction and possible injury. It
could also cause the malfunction
indicator light to come on.
. Never pour fuel into the throttle body
to attempt to start your vehicle.
. Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
— Always place the container on the ground when filling.
— Do not use electronic devices when filling.
— Keep the pump nozzle in contact with the container while you are
filling it.
— Use only approved portable fuel containers for flammable liquid.
CAUTION
. If fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage. .
Insert the cap straight into the fuel-
filler tube, then tighten until the fuel-
filler cap clicks. Failure to tighten the
fuel-filler cap properly may cause the
malfunction indicator light (MIL)
to illuminate. If thelight illumi-
nates because the fuel-filler cap is
loose or missing, tighten or install the
cap and continue to drive the vehicle.
The
light should turn off after a
few driving trips. If thelight does
not turn off after a few driving trips,
have the vehicle inspected. It is
recommended you visit an INFINITI
retailer for this service.
. The Loose Fuel Cap warning will
appear if the fuel-filler cap is not
properly tightened. It may take a few
driving trips for the message to be
displayed. Failure to tighten the fuel-
filler cap properly after the Loose
Fuel Cap warning appears may cause
the
Malfunction Indicator Light
(MIL) to illuminate.
Turn the cap counterclockwise to remove.
To tighten, turn the cap clockwise until a
single click is heard.
Pre-driving checks and adjustments3-27

5-122Starting and driving
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 harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steer-
ing.
If the engine stops or the drive belt breaks,
you will still have control of the vehicle.
However, much greater steering effort is
needed, especially in sharp turns and at low
speeds.
BRAKING PRECAUTIONS
The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking ability at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed
slowly. This is not a malfunction and in-
dicates that the brake assist mechanism is
operating properly.
Hydraulically-assisted brakes
The hydraulically-assisted brake system is
designed to use a hydraulic pump driven
electrically, to assist braking. If the engine
stops, you can stop the vehicle by depressing
the foot brake pedal. However, greater foot
pressure on the foot brake pedal will be
required to stop the vehicle. 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 tapping 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.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced, in
order to assure the best braking perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended you visit
an INFINITI retailer for this service.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will cause overheating of
the brakes, wearing out the brake and pads
faster and reduce gas mileage.
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.
WARNING
.
While driving on a slippery surface,
be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels

CAUTION
.Do not ground accessories directly to
the battery terminal. Doing so will
bypass the variable voltage control
system and the vehicle battery may
not charge completely.
. Use electrical accessories with the
engine running to avoid discharging
the vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage gen-
erated by the generator.

WARNING
Be sure the ignition switch is in the OFF
or LOCK position before servicing drive
belts. The engine could rotate unexpect-
edly.
1. Visually inspect each belt for signs of unusual wear, cuts, fraying or looseness. If the belt is in poor condition or loose,
have it replaced or adjusted. It is recom-
mended you visit an INFINITI retailer for
this service.
2. Have the belts checked regularly for condition and tension in accordance with
the maintenance schedule shown in the
“9. Maintenance and schedules” section.
