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.
OPENER OPERATION
The fuel-filler door release is located below
the instrument panel. To open the fuel-filler
door, pull the release. To lock, close the fuel-
filler door securely.
FUEL-FILLER CAP
WARNING
∙ Gasoline is extremely flammable andhighly 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 mal-
function and possible injury. It could
also cause the
Malfunction Indi-
cator Light (MIL) to come on.
∙ Never pour fuel into the throttle body to attempt to start your vehicle.

3-26Pre-driving checks and adjustments

∙ Do not stop or park the vehicle overflammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously re-
duce the three-way catalyst’s ability
to help reduce exhaust pollutants.
∙ Keep your engine tuned up. Malfunc- tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if no-
ticeable loss of performance or other
unusual operating conditions are de-
tected. Have the vehicle inspected
promptly. It is recommended that you
visit a NISSAN dealer for this service.
∙ Avoid driving with an extremely low fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
∙ Do not race the engine while warming it up. ∙ Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check all your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously illu-
minated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the malfunc-
tion indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions
may occur for a variety of reasons, includ-
ing the installation of replacement or alter-
nate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale af ter replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

Af ter Step 3 is performed, when the
ignition switch is pushed without de-
pressing the brake pedal, the ignition
switch position will change to the ACC
position.
4. Push the ignition switch while depress- ing the brake pedal within 10 seconds
af ter the chime sounds. The engine will
start.
NOTE: ∙ When the ignition switch is pushed to
the ACC or ON position or the engine
is started by the above procedure, the
Intelligent Key battery discharge in-
dicator appears in the vehicle infor-
mation display even when the Intelli-
gent Key is inside the vehicle. This is
not a malfunction. To turn off the In-
telligent Key battery discharge indi-
cator, touch the ignition switch with
the Intelligent Key again.
∙ If the Intelligent Key battery dis-
charge indicator appears, replace the
battery as soon as possible. For addi-
tional information, refer to “Battery
replacement” in the “Do-it-yourself ”
section of this manual.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 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
lights and audible reminders” in the “In-
struments and controls” section of this
manual.

off.
Accelerator downshif t
— in D (Drive) position —
For passing or hill climbing, depress the
accelerator pedal to the floor. This shif ts
the transmission down into a lower gear,
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 de-
creased 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, refer to “Malfunction Indicator
Light (MIL)” in the “Instruments and con-
trols” section of this manual. This will oc-
cur even if all electrical circuits are func-
tioning properly. In this case, place the
ignition switch in the OFF position and
wait for 10 seconds. Then push the
switch back to the ON position. The ve-
hicle should return to its normal operat-
ing condition. If it does not return to its
