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.

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 all four 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 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.

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.
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. For addi-
tional information, refer to “Overdrive OFF indica-
tor 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

Starting and driving5-19

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. For additional information, refer
to “Malfunction Indicator Light (MIL)” in the
“Instruments and controls” section of this
manual. 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 notreturn 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.
CAUTION
● Do not rest your foot on the clutch pedal
while driving. This may cause clutch
damage.
● Fully depress the clutch pedal before
shifting to help prevent transmission
damage.
● Stop your vehicle completely before
shifting into R (Reverse) .
● When the vehicle is stopped with the
engine running (for example, at a stop
light) , shift to N (Neutral) and release
the clutch pedal with the foot brake
applied.
● Do not shift to the “N” (Neutral) position
while driving. Doing so may result in an
accident due to loss of engine braking.
5-20Starting and driving

2.Manual transmission models
Place the shift lever in the R (Reverse) posi-
tion. When parking on an uphill grade, place
the shift lever in 1st gear.
Continuously Variable Transmission
(CVT) models
Move the shift lever into the P (Park) position.
3. To help prevent the vehicle from rolling into traffic when parked on an incline, it is a good
practice to turn the wheels as illustrated.
● HEADED DOWNHILL WITH CURB
1:
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
● HEADED UPHILL WITH CURB
2:
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
● HEADED UPHILL OR DOWNHILL, NO
CURB
3:
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 illumi-
nates while the engine is running, it may indicate
the power steering system is not functioning
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, refer to “Power steer-
ing warning light” in the “Instruments and con-
trols” section of this manual.
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. For additional in-
formation, refer to the ”Tire and load-
ing information label” in the “Techni-
cal and consumer information”
section of this manual.
– For additional information, refer to “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The ABS controls the brakes so the wheels do
not lock during hard braking or when braking on
slippery surfaces. The system detects the rota-
tion speed at each wheel and varies the brake
fluid pressure to prevent each wheel from locking
and sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain steering
control and helps to minimize swerving and spin-
ning on slippery 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 one or more wheels
are close to locking up, the actuator rapidly ap-
plies 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.
BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional brake booster even with light pedal force.
WARNING
The brake assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. it is the driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle at all times.
