FUEL-FILLER CAP
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 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
• Do not use E–15 or E–85 fuel in your
vehicle. For additional information,
refer to “Fuel recommendation” in
the “Technical and consumer infor-
mation” section of this manual. •
The LOOSE FUEL CAP warning mes-
sage 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 af ter the
LOOSE FUEL CAP warning message
appears may cause the
Mal-
function Indicator Light (MIL) to
illuminate.
• Failure to tighten the fuel-filler cap
properly may cause the
Mal-
function Indicator Light (MIL) to illu-
minate. If the
light illuminates
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 af ter a few
driving trips. If thelight does not
turn off af ter a few driving trips, have
the vehicle inspected. It is recom-
mended that you visit a NISSAN
dealer for this service.
• For additional information, refer to
“Malfunction Indicator Light (MIL)” in
the “Instruments and controls” sec-
tion of this manual.
• If fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage.

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 and clutch fluid (if so equipped),
and windshield-washer fluid as fre-
quently 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 placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.

5-20Starting and driving

OFF position:
For normal driving and fuel economy, use
the OFF position.
ON position:
For driving up or down long slopes where
engine braking is necessary, or for powerful
acceleration, use the ON position. The
transmission will automatically select a dif-
ferent gear ratio, allowing the engine to
provide high output.
Remember not to drive at high speeds for
extended periods of time with the drive
sport mode in the ON position. This re-
duces fuel economy.
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.
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
normal operating condition, have the
transmission checked and repaired, if
necessary. 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.
MANUAL TRANSMISSION (if so
equipped)
WARNING
• Do not downshif t abruptly on slip-
pery roads. This may cause a loss of
control.
• Do not over-rev the engine when
shif ting to a lower gear. This may
cause a loss of control or engine
damage.
• Do not shif t to the N (Neutral) posi-
tion while driving. Doing so may re-
sult in an accident due to loss of en-
gine braking.
CAUTION
• Do not rest your foot on the clutch
pedal while driving. This may cause
clutch damage.
• Fully depress the clutch pedal before
shif ting to help prevent transmission
damage.
• Stop your vehicle completely before
