WARNING
∙ Never allow anyone to ride in thecargo 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 sliding
or shif ting. Do not place cargo higher
than the seatbacks. In a sudden 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 po-
sition. If they are not completely se-
cured, 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 seriously
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.

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 mal-
function and possible injury. It could
also cause the
Malfunction Indi-
cator Light (MIL) to come on.

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 po- sition 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 device (which may have caused the in-
terference) separate from the regis-
tered 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, coolant, 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 appear- ance and condition. Also check tires for
proper inflation.
∙ Lock all doors.
∙ Position seat and adjust headrests/head restraints.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passen- gers to do likewise.
∙ Check the operation of warning lights when the ignition switch is pushed to
the ON position. For additional informa-
tion, refer to “Warning lights, indicator
