HOOD FUEL-FILLER DOOR
Pre-driving checks and adjustments3-25

CAUTION
Be careful when opening and exiting
the driver’s side rear door if the fuel-
filler door is open. This may cause dam-
age to the driver’s side rear door or
fuel-filler door if you open fully and
they make contact.
GASOLINE FUEL ENGINES
WARNING
• Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seri-
ously injured if it is misused or mis-
handled. Always stop the engine and
do not smoke or allow open flames
or sparks near the vehicle when
refueling. •
Do not attempt to top off the fuel
tank af ter the fuel pump nozzle
shuts off automatically. Continued
refueling 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
Malfunc-
tion Indicator Light (MIL) to come on.
• Never pour fuel into the throttle body
to attempt to start your vehicle.
• Do not fill a portable fuel container
on a truck bed liner, rubber truck bed
mat or other insulating material.
Static electricity can cause an explo-
sion 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.LPD2594

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedures:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake fluid and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Check that all doors are closed.
• Position seat and adjust head restraints/ headrests.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-12). 1. Apply the parking brake.
2. Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
unless the shif t lever is in either P
(Park) or N (Neutral).
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the igni-
tion switch in any position.
• If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator
pedal a little (approximately 1/3 to the
floor) and while holding, crank the en-
gine. Release the accelerator pedal
when the engine starts.
• If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch to
the ON position to start cranking the
engine. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition
switch to the LOCK position. Af ter
