●Do not place objects with sharp edges
on the seat. Also, do not place heavy
objects on the seat that will leave per-
manent impressions in the seat. Such
objects can damage the seat or Occu-
pant Classification Sensors (weight
sensors) . This can affect the operation
of the air bag system and result in seri-
ous personal injury.
● Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or Occupant Classifi-
cation Sensors. This can also affect the
operation of the air bag system and
result in serious personal injury.
● Immediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
● No unauthorized changes should be
made to any components or wiring of
the supplemental air bag system. This is
to prevent accidental inflation of the
supplemental air bag or damage to the
supplemental air bag system. ●
Do not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or front end structure.
This could affect proper operation of
the front air bag system.
● Tampering with the front air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument
panel assembly by placing material
over the steering wheel pad and above
the instrument panel or by installing
additional trim material around the air
bag system.
● Removing or modifying the front pas-
senger seat may affect the function of
the air bag and result in serious per-
sonal injury. ●
Modifying or tampering with the front
passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing mate-
rial on the seat cushion or by installing
additional trim material, such as seat
covers, on the seat that are not specifi-
cally designed to assure proper air bag
operation. Additionally, do not stow any
objects under the front passenger seat
or the seat cushion and seatback. Such
objects may interfere with the proper
operation of the Occupant Classifica-
tion Sensor (weight sensor) .
● No unauthorized changes should be
made to any components or wiring of
the seat belt system. This may affect the
front air bag system. Tampering with
the seat belt system may result in seri-
ous personal injury.

hicle information display” in this section.
To turn on the autolight system:1. Turn the headlight switch to the AUTO posi- tion
1.
2. Turn the ignition switch to ON.
3. The autolight system automatically turns the headlights on and off.
Initially, if the ignition switch is turned OFF and a
door is opened and left open, the headlights
remain ON for a period of time. If another door is
opened while the headlights are on, then the
timer is reset.
To turn the autolight system off, turn the switch to
the OFF,
,orposition. Be sure you do not put anything on top of
the autolight sensor located in the top side
of the instrument panel. The autolight sen-
sor controls the autolight; if it is covered,
the autolight sensor reacts as if it is dark
out and the headlights will illuminate. If
this occurs while parked with the engine off
and the ignition switch placed in the ON
position, your vehicle’s battery could be-
come discharged.

OPERATING TIPS
●When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is
not a malfunction. After the coolant tempera-
ture warms up, air flow from the foot outlets
will operate normally. The sunload sensor, located on the top driver’s
side of the instrument panel, helps the system
maintain a constant temperature. Do not put any-
thing on or around this sensor.

●When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CAUTION
Do not place metalized film or any metal
parts (antenna, etc.) on the windows. This
may cause poor reception of the signals
from the tire pressure sensors, and the
TPMS will not function properly.
Some devices and transmitters may temporarily
interfere with the operation of the TPMS and
cause the low tire pressure warning light to illu-
minate. Some examples are:
– Facilities or electric devices using similar radio
frequencies are near the vehicle.
– If a transmitter set to similar frequencies is being used in or near the vehicle.
– If a computer (or similar equipment) or a DC/AC converter is being used in or near the
vehicle.

1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shift lever to the P (Park) position.
3. Place the ignition switch to the ON position. Do not start the engine.
Operation: 1. Add air to the tire.
2. After a few seconds, the hazard indicators will start flashing.
Starting and driving5-5

3. When the designated pressure is reached,the horn beeps once and the hazard indica-
tors stop flashing.
4. Perform the above steps for each tire. ●If the tire is over-inflated more than ap-
proximately 4 psi (30 kPa) , the horn
beeps and the hazard indicators flash
three times. To correct the pressure, push
the core of the valve stem on the tire
briefly to release pressure. When the
pressure reaches the designated pres-
sure, the horn beeps once.
● If the hazard indicator does not flash
within approximately 15 seconds after
starting to inflate the tire, it indicates that
the Easy Fill Tire Alert is not operating.
● The TPMS will not activate the Easy Fill
Tire Alert under the following conditions:
– If there is interference from an external device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the tire.
– There is a malfunction in the TPMS sys- tem.
– There is a malfunction in the horn or haz- ard indicators. – The identification code of the tires pres-
sure sensor is not registered to the sys-
tem.
– The battery of the tire pressure sensor is low.
● If the Easy Fill Tire Alert does not operate
due to TPMS interference, move the ve-
hicle about 3 ft (1 m) backward or forward
and try again.
If the Easy Fill Tire Alert is not working, use a tire
pressure gauge.
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss of
control or an accident.
Be alert and drive defensively at all times. Obey
all traffic regulations. Avoid excessive speed,
high speed cornering, or sudden steering ma-
neuvers, because these driving practices could
cause you to lose control of your vehicle. As with
any vehicle, loss of control could result in a
collision with other vehicles or objects or
cause the vehicle to roll over, particularly if
the loss of control causes the vehicle to slide sideways.
Be attentive at all times, and
avoid driving when tired. Never drive when under
the influence of alcohol or drugs (including pre-
scription or over-the-counter drugs which may
cause drowsiness) . Always wear your seat belt
as outlined in the “Safety – Seats, seat belts and
supplemental restraint system” section of this
manual, and also instruct your passengers to do
so.
Seat belts help reduce the risk of injury in colli-
sions and rollovers. In a rollover crash, an
unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a
seat belt.
OFF-ROAD RECOVERY
While driving, the right side or left side wheels
may unintentionally leave the road surface. If this
occurs, maintain control of the vehicle by follow-
ing the procedure below. Please note that this
procedure is only a general guide. The vehicle
must be driven as appropriate based on the con-
ditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course.
5-6Starting and driving

– When installing a spare tire, makesure that it is the proper size and type
as specified on the Tire and Loading
Information label. Refer to “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” 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 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 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.

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving conditions,
the VDC System helps to perform the following
functions:● Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
● Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
● Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss of
vehicle control in all driving situations. When the VDC system operates, theindi-
cator in the instrument panel flashes to note the
following:
● The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
● You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
● Adjust your speed and driving to the road
conditions.
For additional information, refer to “Slip indicator
light” and ”Vehicle Dynamic Control (VDC) off
indicator light” in the ”Instruments and controls”
section of this manual.
If a malfunction occurs in the system, the
indicator light comes on in the instrument panel.
The VDC system automatically turns off when the
indicator light is off.
The VDC OFF switch is used to turn off the VDC
system. The
indicator illuminates to indi-
cate the VDC system is off.
When the VDC switch is used to turn off the
system, the VDC system still operates to prevent
one drive wheel from slipping by transferring
power to a non slipping drive wheel. The
indicator flashes if this occurs. All other VDC
functions are off and the
indicator will not
flash.
The VDC system is automatically reset to ON
when the ignition switch is placed in the OFF
position then back to the ON position.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in reverse
at a slow speed. When the self-test occurs, you
may hear a clunk noise and/or feel a pulsation in
the brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
● The VDC system is designed to help the
driver maintain stability but does not
prevent accidents due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully.
