the vehicle must be driven at speeds
above 16 mph (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
The “Tire Pressure Low - Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the low
tire pressure warning light remains
illuminated.
For additional information, see “Vehicle in-
formation display — 7 inch (18 cm) Type B”
(P. 2-34), and “Tire Pressure Monitoring Sys-
tem (TPMS)” (P. 5-5) and (P. 6-3).
TPMS malfunction
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is placed in the ON position. The
light will remain on af ter 1 minute. Have the
system checked. It is recommended that
you visit a NISSAN dealer for this service.
The "Tire Pressure Low — Add Air" warning
does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
For additional information, see “Tire Pres-
sure Monitoring System (TPMS)” (P. 5-5) and
(P. 6-3).
WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
• If the light does not illuminate with
the ignition switch placed in the ON
position, have the vehicle checked as
soon as possible. It is recommended
that you visit a NISSAN dealer for this
service.
• If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle
speed, pull off the road to a safe loca-
tion and stop the vehicle as soon as
possible. Driving with under-inflated
tires may permanently damage the
tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an acci-
dent and could result in serious per-
sonal injury or death. Check the tire
pressure for all four tires. Adjust the
tire pressure to the recommended
COLD tire pressure show on the Tire
and Loading Information label lo-
cated in the driver’s door opening to turn the low tire pressure warning
light off. If the light still illuminates
while driving af ter adjusting the tire
pressure, a tire may be flat or the
TPMS may be malfunctioning. If you
have a flat tire, replace it with a spare
tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit a NISSAN
dealer for this service.
• When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for these services.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
2-14Instruments and controls

CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.
• If the vehicle is being driven at
speeds of less than 16 mph (25 km/h),
the TPMS may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.
Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or
blinks while the engine is running, it may
indicate a potential emission control
malfunction.
The MIL may also come on steady if the
fuel-filler cap is loose or missing, or if the
vehicle runs out of fuel. Check to make sure
the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3
gallons (11.4 liters) of fuel in the fuel tank.
Af ter a few driving trips, the
light
should turn off if no other potential emis-
sion control system malfunction exists. If this indicator light comes on steady for 20
seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance
test. For additional information, see “Readi-
ness for Inspection/Maintenance (I/M) test”
(P. 10-24).
Operation
The MIL will come on in one of two ways:
• MIL on steady — An emission control sys-
tem malfunction has been detected.
Check the fuel-filler cap if the Loose Fuel
Cap warning appears in the vehicle infor-
mation display. If the fuel-filler cap is loose
or missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off af ter a few driving
trips. If thelight does not turn off
af ter a few driving trips, have the vehicle
inspected. It is recommended that you
visit a NISSAN dealer for this service. You
do not need to have your vehicle towed
to the dealer.
• MIL blinking — An engine misfire has been detected which may damage the emis-
sion control system. To reduce or avoid
emission control system damage:– do not drive at speeds above 45 mph (72 km/h). – avoid hard acceleration or
deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.
The MIL may stop blinking and come on
steady. Have the vehicle inspected. It is rec-
ommended that you visit a NISSAN dealer
for this service. You do not need to have
your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without
having the emission control system
checked and repaired as necessary
could lead to poor driveability, reduced
fuel economy, and possible damage to
the emission control system.
Master warning light
When the ignition is in the ON position, the
master warning light illuminates if any of
the following are displayed on the vehicle
information display.
• No key warning
• Low windshield-washer fluid warning
• Door open warning (when stopped)
• Trunk open warning

Owner’s Manual
This warning may appear if there is a large
difference between the diameters of the
front and rear wheels. Pull off the road in a
safe area, with the engine idling. Check that
all the tire sizes are the same, that the tirepressure is correct and that the tires are
not excessively worn.
CVT (AT) Malfunction
Service now
This warning appears when there is a
problem with the CVT system. If this
warning appears, have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
CVT (AT) hot Power reduced
This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
climbing steep grades in high tempera-
tures with heavy loads, such as when tow-
ing a trailer), engine power and, under
some conditions, vehicle speed will be de-
creased automatically to reduce the
chance of transmission damage. Vehicle
speed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be reduced.

WARNING
Failure to follow the warnings and in-
structions for the proper use of the In-
telligent Around View Monitor system
could result in serious injury or death
• The Intelligent Around View Monitor
is a convenience feature and is not a
substitute for proper vehicle opera-
tion because it has areas where ob-
jects cannot be viewed. The four cor-
ners of the vehicle in particular, are
areas where objects do not always
appear in the bird’s-eye, front, or rear
views. Always check your surround-
ings to be sure that it is safe to move
before operating the vehicle. Always
operate the vehicle slowly.
• The driver is always responsible for
safety during parking and other
maneuvers.
CAUTION
Do not scratch the camera lens when
cleaning dirt or snow from the front of
the camera. The Intelligent Around View Monitor sys-
tem is designed as an aid to the driver in
situations such as slot parking or parallel
parking.
The monitor displays various views of the
position of the vehicle in a split screen for-
mat. Not all views are available at all times.
Available views:
• Front View
An approximately 150–degree view of the
front of the vehicle.
• Rear View An approximately 150–degree view of the
rear of the vehicle.
• Bird's-Eye View The surrounding views of the vehicle
from above.
• Front-Side View The view around and ahead of the front
passenger's side wheel.
• Full Screen Rear View The view to the rear of the vehicle (which
is a little wider than the standard Rear
View). To display the multiple views, the Intelligent
Around View Monitor system uses cam-
eras located in the front grille, on the vehi-
cle’s outside mirrors and one just above
the vehicle’s license plate
O1.

Additional information:
• When using a wheel without the TPMSsuch as the spare tire, the TPMS does not
monitor the tire pressure of the spare tire.
• The TPMS will activate only when the ve- hicle is driven at speeds above 16 mph (25
km/h). Also, this system may not detect a
sudden drop in tire pressure (for example,
a flat tire while driving).
• The low tire pressure warning light does not automatically turn off when the tire
pressure is adjusted on all four tires. Af ter
all four tires are inflated to the recom-
mended pressure, the vehicle must be
driven at speeds above 16 mph (25 km/h)
to activate the TPMS and turn off the low
tire pressure warning light. Use a tire
pressure gauge to check the tire
pressure.
• The “Tire Pressure Low - Add Air” warning appears in the vehicle information dis-
play when the low tire pressure warning
light is illuminated and low tire pressure is
detected. The “Tire Pressure Low - Add
Air” warning turns off when the low tire
pressure warning light turns off. • The “Tire Pressure Low - Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the
low tire pressure warning light remains
illuminated.
• The “Tire Pressure Low - Add Air” warning does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
• Tire pressure rises and falls depending on the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure af ter driving be-
cause the tire pressure rises af ter driving.
Low outside temperature can lower the
temperature of the air inside the tire
which can cause a lower tire inflation
pressure. This may cause the low tire
pressure warning light to illuminate. If the
warning light illuminates, check the tire
pressure for all four tires.
• The Tire and Loading Information label is located in the driver's door opening.
• You can also check the tire pressure of all tires (except the spare) on the vehicle in-
formation display screen. The order of
the tire pressure figures displayed on the
screen corresponds with the actual order
of the tire position. For additional information, see “Low tire
pressure warning light” (P. 2-13), “Tire Pres-
sure Monitoring System (TPMS)” (P. 6-3) and
“Tire pressure” (P. 8-29).
WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
5-6Starting and driving

•For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shif t the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or per-
sonal injury.
• Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamom-
eters used by some states for emis-
sions testing) or similar equipment
even if the other two wheels are
raised off the ground. Make sure you
inform test facility personnel that
your vehicle is equipped with AWD
before it is placed on a dynamom-
eter. Using the wrong test equipment
may result in drivetrain damage or
unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.
• When a wheel is off the ground due to
an unlevel surface, do not spin the
wheel excessively. •
Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
• If at all possible, avoid sharp turning
maneuvers, particularly at high
speeds. Your NISSAN vehicle has a
higher center of gravity than a pas-
senger car. The vehicle is not de-
signed for cornering at the same
speeds as passenger cars.
• Failure to operate this vehicle cor-
rectly could result in loss of control
and/or a rollover accident.
• Always use tires of the same type,
size, brand, construction (bias, bias-
belted, or radial), and tread pattern
on all four wheels. Install tire chains
on the front wheels when driving on
slippery roads and drive carefully.
• Be sure to check the brakes immedi-
ately af ter driving in mud or water.
For additional information, see
“Brake precautions” (P. 5-173).
• Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured. •
Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent mainte-
nance may be required. For addi-
tional information, see “Maintenance
under severe operating conditions”
(P. 9-7).
5-12Starting and driving

•Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamom-
eters used by some states for emis-
sions testing) or similar equipment
even if the other two wheels are
raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with
AWD before it is placed on a dyna-
mometer. Using the wrong test
equipment may result in drivetrain
damage or unexpected vehicle
movement which could result in seri-
ous personal injury or vehicle
damage.
CAUTION
• Do not operate the engine on a free
roller when any of the wheels are
raised.
• If you use the free roller, rotate four
wheels with the same speed without
raising any wheels. •
If an AWD warning message is dis-
played while driving there may be a
malfunction in the AWD system. Re-
duce the vehicle speed immediately
and have your vehicle checked. It is
recommended that you visit a
NISSAN dealer as soon as possible.
• The powertrain may be damaged if
you continue driving when the AWD
temperature or tire size incorrect
messages are displayed
• If the AWD high temperature mes-
sage is displayed while you are driv-
ing, pull off the road in a safe area,
and idle the engine. The driving
mode will change to 2WD to prevent
the AWD system from malfunction-
ing. If the warning message turns off,
you can drive again.
• If the tire size incorrect message is
displayed while you are driving, pull
off the road in a safe area with the
engine idling. Check that all tire sizes
are the same, that the tire pressure is
correct and that the tires are not ex-
cessively worn. •
If a warning message continues to be
displayed af ter the above opera-
tions, have your vehicle checked as
soon as possible. It is recommended
that you visit a NISSAN dealer for this
service.
5-170Starting and driving

•Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
– When installing a spare tire, make
sure that it is the proper size and
type as specified on the Tire and
Loading Information label. For ad-
ditional information, see “Tire and
Loading Information label”
(P. 10-14).
– For additional information, see
“Wheels and tires” (P. 8-29).
The 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 slippery surfaces.Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate 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 Anti-lock Braking System (ABS) in-
cludes 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 mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates 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 ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds abov
e3-6mph(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 applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion 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 op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
5-174Starting and driving

The chassis control is an electric control
module that includes the following
functions:
• Intelligent Trace Control
• Active Ride Control
INTELLIGENT TRACE CONTROL
(I-TC)
This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels to aid tracing at corners
and help smooth vehicle response.
The I-TC can be set to on (enabled) or off
(disabled) through the vehicle information
display “Settings” page. For additional infor-
mation, see “Vehicle information display —
5 inch (13 cm) Type A (if so equipped)”
(P. 2-18) or “Vehicle information display — 7
inch (18 cm) Type B (if so equipped)” (P. 2-34).
When the VDC system is turned off, the I-TC
is also turned off.
WARNING
The I-TC may not be effective depend-
ing on the driving condition. Always
drive carefully and attentively. When the I-TC is operating, you may feel a
pulsation in the brake pedal and hear a
noise. This is normal and indicates that the
I-TC is operating properly.
Even if the I-TC is turned off, some functions
will remain on to assist the driver (for ex-
ample, avoidance scenes).
ACTIVE RIDE CONTROL (ARC)
This system senses upper body motion
(based on wheel speed information) and
controls engine torque and four wheel
brake pressure. This will enhance ride com-
fort in effort to restrain uncomfortable up-
per body movement when passing over
undulated road surfaces. This system
comes into effect above 25 mph (40 km/h).
When the VDC system is turned off, the ARC
is also turned off.
When the ARC is operating, you may hear
noise and sense slight deceleration. This is
normal and indicates that the ARC is oper-
ating properly.
WARNING
• Never rely solely on the hill start as-
sist system to prevent the vehicle
from moving backward on a hill. Al-
ways drive carefully and attentively.
Depress the brake pedal when the
vehicle is stopped on a steep hill. Be
especially careful when stopped on a
hill on frozen or muddy roads. Failure
to prevent the vehicle from rolling
backwards may result in a loss of
control of the vehicle and possible
serious injury or death.
• The hill start assist system is not de-
signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Failure to do so may cause
the vehicle to roll backwards and
may result in a collision or serious
personal injury.
• The hill start assist system may not
prevent the vehicle from rolling
backwards on a hill under all load or
road conditions. Always be prepared
to depress the brake pedal to prevent
the vehicle from rolling backwards.
Failure to do so may result in a colli-
sion or serious personal injury.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pres-
sure Monitoring system (TPMS). It monitors
tire pressure of all tires except the spare.
When the low tire pressure warning light is
lit, and the “Tire Pressure Low - Add Air”
warning appears in the vehicle information
display, one or more of your tires is signifi-
cantly under-inflated. If equipped, the sys-
tem also displays pressure of all tires (ex-
cept the spare tire) on the display screen by
sending a signal from a sensor that is in-
stalled in each wheel. If the vehicle is being
driven with low tire pressure, the TPMS will
activate and warn you of it by the low tire
pressure warning light. This system will ac-
tivate only when the vehicle is driven at
speeds above 16 mph (25 km/h). For addi-
tional information, see “Warning lights, indi-
cator lights and audible reminders” (P. 2-9)
and “Tire Pressure Monitoring System
(TPMS)” (P. 5-5).
WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
• If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving af-
ter adjusting the tire pressure, a tire
may be flat or the TPMS may be mal-
functioning. If you have a flat tire, re-
place it with a spare tire as soon as possible. If no tire is flat and all tires
are properly inflated, have the ve-
hicle checked. It is recommended
that you visit a NISSAN dealer for this
service.
• When using a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately one minute. Have
your tires replaced and/or TPMS sys-
tem reset as soon as possible. It is
recommended that you visit a
NISSAN dealer for these services.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• The Genuine NISSAN Emergency Tire
Repair Sealant or equivalent can be
used for temporarily repairing a tire.
Do not inject any other tire liquid or
aerosol tire sealant into the tires, as
this may cause a malfunction of tire
pressure sensors.
