SONAR SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the sonar function. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
● Inclement weather or ultrasonic
sources such as an automatic car wash,
a trucks’s compressed-air brakes or a
pneumatic drill may affect the function
of the system, including reduced perfor-
mance or a false activation.
● The system is not designed to prevent
contact with small or moving objects.
● The system will not detect small objects
below the bumper, and may not detect
objects close to the bumper or on the
ground.
● The system may not detect the follow-
ing objects:
– Fluffy objects such as snow, cloth, cotton, grass or wool.
– Thin objects such as rope, wire or chain.
– Wedge-shaped objects. ●
If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
jects or false alarms.
CAUTION
Excessive noise (such as audio system vol-
ume or an open vehicle window) will inter-
fere with the tone and it may not be heard.
System temporarily unavailable
When the amber markers are displayed at the
corners of the vehicle icon and the function can-
not be activated from the Camera setting menu
(the setting items are grayed out) , the sonar
system may be malfunctioning.
SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar sensors
(located on the front and rear bumper fas-
cia) free from accumulations of snow, ice
and dirt. Do not scratch the surface of the
sonar sensors when cleaning. If the sen-
sors are covered, the accuracy of the sonar
function will be diminished.

audible signals outside the vehicle to help you
inflate the tires to the recommended COLD tire
pressure.
Vehicle set-up1. 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.
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 tire 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.ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than passen-
ger cars to make them capable of performing in a
variety of on-pavement and off-road applications.
This gives them a higher center of gravity than
ordinary vehicles. An advantage of higher ground
clearance is a better view of the road, allowing
you to anticipate problems. However, they are not
designed for cornering at the same speeds as
conventional 2-wheel drive vehicles any more
than low-slung sports cars are designed to per-
form satisfactorily under off-road conditions. If at
all possible, avoid sharp turns at high speeds. As
with other vehicles of this type, failure to operate
this vehicle correctly may result in loss of control
or vehicle rollover. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt.
For additional information, refer to “Driving safety
precautions” in this section.
5-6Starting and driving

●As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive or
absentminded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed
by depressing the brake pedal, depend-
ing on the distance to the vehicle ahead
and the surrounding circumstances in
order to maintain a safe distance be-
tween vehicles.
● If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill
within the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
● Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance.
The ICC system may not be able to
maintain the selected distance between
vehicles (following distance) or se-
lected vehicle speed under some
circumstances. ●
The system may not detect the vehicle
in front of you in certain road or weather
conditions. To avoid accidents, never
use the ICC system under the following
conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources. ●
Do not use the ICC system if you are
towing a trailer. The system may not
detect a vehicle ahead.
● In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The radar sensor will not detect the following
objects: ● Stationary and slow moving vehicles
● Pedestrians or objects in the roadway
● Oncoming vehicles in the same lane
● Motorcycles traveling offset in the travel lane
The following are some conditions in which the
sensor cannot properly detect a vehicle ahead
and the system may not operate properly: ● When snow or road spray from traveling
vehicles reduces the sensor’s detection.

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. It is recommended that you visit a
NISSAN dealer for this service.
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.
The VDC system uses various sensors to monitor
driver inputs and vehicle motion. Under certain
driving conditions, the VDC system helps to per-
form 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.

Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. For additional information,
refer to “Wheels and tires” in the “Technical and
consumer information” section of this manual.
WARNING
●The use of tires other than those recom-
mended or the mixed use of tires of
different brands, construction (bias,
bias-belted or radial) , or tread patterns
can adversely affect the ride, braking,
handling, Vehicle Dynamic Control
(VDC) system, ground clearance, body-
to-tire clearance, tire chain clearance,
speedometer calibration, headlight aim
and bumper height. Some of these ef-
fects may lead to accidents and could
result in serious personal injury.
● If your vehicle was originally equipped
with 4 tires that were the same size and
you are only replacing 2 of the 4 tires,
install the new tires on the rear axle.
Placing new tires on the front axle may
cause loss of vehicle control in some
driving conditions and cause an acci-
dent and personal injury. ●
If the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade ve-
hicle handling characteristics, affect the
VDC system and/or interference with
the brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear. For addi-
tional information on wheel off-set di-
mensions, refer to “Wheels and tires” in
the “Technical and consumer informa-
tion” section of this manual.
● Since the spare tire is not equipped with
the TPMS, 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 warn-
ing light will flash for approximately
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit a NISSAN dealer for this service.
● Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS. ●
The TPMS sensor may be damaged if it
is not handled correctly. Be careful
when handling the TPMS sensor.
● When replacing the TPMS sensor, the
ID registration may be required. It is
recommended that you visit a NISSAN
dealer for ID registration.
● Do not use a valve stem cap that is not
specified by NISSAN. The valve stem
cap may become stuck.
● Be sure that the valve stem caps are
correctly fitted. Otherwise the valve may
be clogged up with dirt and cause a
malfunction or loss of pressure.
● Do not install a damaged or deformed
wheel or tire even if it has been re-
paired. Such wheels or tires could have
structural damage and could fail with-
out warning.
● The use of retread tires is not
recommended.
● For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
