Do not place the support rod in a location
other than the designated slot.
Hold the coated parts
Awhen removing or
resetting the support rod. Avoid direct con-
tact with the metal parts, as they may be
hot immediately after the engine has been
stopped.
When closing the hood, return the support rod to
its original position, lower the hood to approxi-
mately 12 in (30 cm) above the latch and release
it. This allows proper engagement of the hood
latch.
WARNING
● Make 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.
● If you see steam or smoke coming from
the engine compartment, to avoid injury
do not open the hood.

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
after 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 emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause
the
Malfunction Indicator Light
(MIL) to come on.
● Never pour fuel into the throttle body to
attempt to start your vehicle.

Pre-driving checks and adjustments3-25

●Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
CAUTION
● Do not use leaded gasoline. Deposits
from 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 driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging 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 in-
flated to the inflation pressure recommended 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 your tires as soon as possible, and inflate
all your tires 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 substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to
trigger illumination 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 mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction 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,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing 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.
Additional information:
● The TPMS does not monitor the tire
pressure of the spare tire.

3. Touch the ignition switch with the IntelligentKey as illustrated. (A chime will sound.)
After step 3 is performed, when the ignition
switch is pushed without depressing the
brake pedal, the ignition switch position will
change to ACC.
4. Push the ignition switch while depressing the brake pedal within 10 seconds after 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 indicator appears in the
vehicle information display even when the
Intelligent Key is inside the vehicle. This is
not a malfunction. To turn off the Intelligent
Key battery discharge indicator, touch the
ignition switch with the Intelligent Key again.
● If the Intelligent Key battery discharge indi-
cator appears, replace the battery as soon
as possible. See “Battery Replacement” in
the “Maintenance and do-it-yourself” sec-
tion.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-
cedure:
1. Leave the ignition switch in the ON position 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 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. ●
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 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 placed in the ON posi-
tion. See “Warning/indicator lights and au-
dible reminders” in the “Instruments and
controls” section of this manual.
BEFORE STARTING THE ENGINE
Starting and driving5-13

D (Drive):
Use this position for all normal forward driving.
L (Low):
Use this position for maximum engine braking on
steep downhill gradients/climbing steep slopes
and whenever approaching sharp bends. Do not
use the L (Low) position in any other circum-
stances.
Shift lock release
If the battery charge is low or discharged, the
shift lever may not be moved from the P (Park)
position even with the brake pedal depressed
and the shift lever button pressed.
It will be necessary to jump start or have your
battery charged, see “Jump starting” in the “In
case of emergency” section. Contact your
NISSAN dealer or a professional towing service.
To move the shift lever, complete the following
procedure:1. Press the ignition switch to the LOCK posi- tion. 2. Apply the parking brake.
3. Using a protective cloth on the tip ofa3mm
screwdriver, remove the shift lock release
cover.
● If available, a plastic trim tool can also be
used.
4. Insert the small screwdriver in the shift lock release slot and push down.
5. Move the shift lever to the N (Neutral) posi- tion while holding down the shift lock re-
lease.
6. Push the ignition switch to the ON position to unlock the steering wheel. Now the ve-
hicle may be moved to the desired location.
If the shift lever cannot be moved out of P (Park) ,
have a NISSAN dealer check the transmission as
soon as possible.
WARNING
If the shift lever cannot be moved from the
P (Park) position while the engine is run-
ning and the brake pedal is depressed, the
stop lights may not work. Malfunctioning
stop lights could cause an accident injur-
ing yourself and others.

5-18Starting and driving

Overdrive (O/D) OFF switch
When the O/D OFF switch is pushed with the
shift lever in the D (Drive) position, the
light in the instrument panel illuminates. See
“Overdrive off indicator light (CVT models)” 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 shift
lever is shifted to any position other than D (Drive) , the Overdrive off mode will be automati-
cally 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 “Instruments and controls”
section. This will occur even if all electrical
circuits are functioning properly. In this
case, place the ignition switch in the OFF
position and wait for 10 seconds. 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 normal operating condition,
have a NISSAN dealer check the transmis-
sion and repair if necessary.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually reduced.
The reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially careful
when driving. If necessary, pull to the side
of the road at a safe place and allow the
transmission to return to normal opera-
tion, or have it repaired if necessary.
MANUAL TRANSMISSION (if so
equipped)
WARNING
●
Do not downshift abruptly on slippery
roads. This may cause a loss of control.
● Do not over-rev the engine when shift-
ing to a lower gear. This may cause a
loss of control or engine damage.
● Do not shift to the N (Neutral) position
while driving. Doing so may result in an
accident due to loss of engine braking.

Turn the wheels toward the side of the road
so the vehicle will move away from the cen-
ter of the road if it moves.
4. Place the ignition switch in the LOCK posi- tion and remove the key.
WARNING
●If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
● When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle but the steering will be
harder to operate. Have the power
steering system checked by a NISSAN
dealer.
The power steering system is designed to pro-
vide power assist while driving to operate the
steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. When the temperature of the power steer-
ing system goes down, the power assist level will
return to normal. Avoid repeating such steering
wheel operations that could cause the power
steering system to overheat. You may hear a sound when the steering wheel is
operated quickly. However, this is not a malfunc-
tion.
If the electric power steering warning light
PS
illuminates while the engine is running, it may
indicate the power steering system is not func-
tioning properly and may need servicing. Have
the power steering system checked by a
NISSAN dealer.
When the electric power steering warning light
illuminates with the engine running, there will be
no power assist for the steering but you will still
have control of the vehicle. At this time, greater
steering effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information see “Power steering
warning light” in the “Instruments and controls”
section.
POWER STEERING
Starting and driving5-29

– When installing a spare tire, makesure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Technical
and consumer information” section
of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h). The speed varies according to road
conditions. When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
and releases hydraulic pressure. This action is
similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
