1. Pull the hood lock release handles1located
below the instrument panel until the hood
springs up slightly.
2. Locate the lever
s2in between the hood and
grille and push the lever sideways with your
fingertips.
3. Raise the hood
s3.
4. Remove the support rod
s4and insert it into
the slot on the underside of the hood
s5.
When closing the hood, first return the support
rod to its original position. Slowly move the hood
down to latch the lock. Push the hood down to
lock the hood securely into place.
WARNING
cMake sure the hood is completely
closed and latched before driving. Fail-
ure to do so could cause the hood to fly
open and result in an accident.
cIf you see steam or smoke coming from
the engine compartment, to avoid injury
do not open the hood.
WARNING
cDo not drive with the trunk lid open. This
could allow dangerous exhaust gases
to be drawn into the vehicle. See “Ex-
haust gas” in the “Starting and driving”
section of this manual.
cClosely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear
seatback and trunk lid securely latched

WARNING
cGasoline 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.
cDo not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
cUse 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 emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause the
malfunction indicator light to come on.
cNever pour fuel into the throttle body to
attempt to start your vehicle.cDo 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 fill-
ing it.
– Use only approved portable fuel con-
tainers for flammable liquid.
CAUTION
cIf fuel is spilled on the vehicle body,
flush it away with water to avoid paint
damage.
cTighten until the fuel-filler cap clicks.
Failure to tighten the fuel-filler cap
properly may cause the
Mal-
function Indicator Light (MIL) to illumi-
nate. If the
light illuminates be-
cause the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle.
The
light should turn off after a
few driving trips. If the
light
does not turn off after a few driving
trips, have the vehicle inspected by a
NISSAN dealer.
cFor additional information, see the
“Malfunction Indicator Light (MIL)” in
the “Instruments and Controls” section
earlier in 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 automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedures:
1. Leave the ignition switch in the ON position
for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK
position, and wait approximately 10 sec-
onds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices.cMake sure the area around the vehicle is
clear.
cCheck fluid levels such as engine oil, cool-
ant, brake and clutch fluid, and window
washer fluid as frequently as possible, or at

To push the shift lock release, complete the fol-
lowing procedure:
1. Turn the ignition key to the LOCK position
and remove the key
2. Apply the parking brake.
3. Remove the shift lock release cover as
shown.
4. Insert a small screwdriver in the shift lock
release slot and push down.
5. Move the shift selector lever to the N (Neu-
tral) position while holding down the shift
lock release.
6. Turn the key to the ON position to unlock the
steering wheel. Now the vehicle may be
moved to the desired location.
If the shift selector lever cannot be moved out of
P (Park) , have a NISSAN dealer check the trans-
mission as soon as possible.
WARNING
If the selector lever cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Overdrive (O/D) OFF switch
When the O/D OFF switch is pushed with the
selector lever in the D (Drive) position, the
light in the instrument panel illuminates. See
“Overdrive off indicator light” in the “Instruments
and controls” section of this manual.
Use the Overdrive off mode when you need im-
proved engine braking.
To turn off the Overdrive off mode, push the O/D
OFF switch again. The
indicator light will
turn off.
Each time the engine is started, or when the
selector lever is shifted to any position other thanD (Drive) , the Overdrive off mode will be auto-
matically turned off.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
When the fail-safe operation occurs, the CVT will
not be shifted into the selected driving position.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. The MIL may
come on to indicate the fail-safe mode is
activated, see “Malfunction indicator light
(MIL)” in the “Instrument and controls” sec-
tion. This will occur even if all electrical
circuits are functioning properly. In this
case, turn the ignition switch to the OFF
position and wait for 10 seconds. Then turn
the switch back to the ON position. The
vehicle should return to its normal operat-
ing condition. If it does not return to its
normal operating condition, have a
NISSAN dealer check the transmission and
repair if necessary.
