WARNING
• Never allow anyone to ride in the
cargo area or on the rear seat when it
is in the fold-down position. Use of
these areas by passengers without
proper restraints could result in seri-
ous injury or death in an accident or
sudden stop.
• Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
• When returning the seatbacks to the
upright position, be certain they are
completely secured in the latched
position. If they are not completely
secured, passengers may be injured
in an accident or sudden stop.
• Closely supervise children when they
are around cars to prevent them
from playing and becoming locked in
the trunk where they could be seri-
ously injured. Keep the car locked,
with the rear seatback and trunk lid
securely latched when not in use, and
prevent children's access to car keys.

FUEL-FILLER CAP
WARNING
•
Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
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 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.

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 procedure:
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 window 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.
• Lock all doors.
• 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 pushed to the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-8). 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
if the shif t lever is in any of the driving
positions.
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

5-14Starting and driving

If the shif t lever cannot be moved out of P
(Park), have the transmission checked as
soon as possible. It is recommended that
you visit a NISSAN dealer for this service.
CAUTION
Make sure to take extra care during the
removal of the shif t lock cap as this
part is easily damaged.
WARNING
If the shif t lever cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is de-
pressed, the stop lights may not work.
Malfunctioning stop lights could cause
an accident injuring yourself and
others.
Accelerator downshif t
— in D (Drive) position and manual
shif t mode
For passing or hill climbing, depress the
accelerator pedal to the floor. This shif ts
the transmission down into lower range,
depending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
when climbing steep grades in high tem-
peratures with heavy loads, such as when
towing a trailer), engine power and, under
some conditions, vehicle speed will be
decreased automatically to reduce the
chance of transmission damage. Vehicle
speed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be limited.
Fail-safe
If the vehicle is driven under extreme
conditions, such as excessive wheel
spinning and subsequent hard braking,
the fail-safe system may be activated.
The Malfunction Indicator Light (MIL)
may come on to indicate the fail-safe
mode is activated. For additional infor-
mation, see “Malfunction Indicator Light
(MIL)” (P. 2-13). This will occur even if all
electrical circuits are functioning prop-
erly. In this case, place the ignition switch
in the OFF position and wait for 10 sec- onds. Then place the ignition switch
back in the ON position. The vehicle
should return to its normal operating
condition. If it does not return to its nor-
mal operating condition, have the trans-
mission checked and repaired, if neces-
sary. It is recommended that you visit a
NISSAN dealer for this service.
WARNING
When the high fluid temperature pro-
tection mode or fail-safe operation oc-
curs, vehicle speed may be gradually
reduced. The reduced speed may be
lower than other traffic, which could in-
crease the chance of a collision. Be es-
pecially careful when driving. If neces-
sary, pull to the side of the road at a safe
place and allow the transmission to re-
turn to normal operation, or have it re-
paired if necessary.
