WARNING
Failure to follow the warnings and
instructions for proper use of the I-
DA system could result in serious
injury or death.
.The I–DA system is only a warning
to inform the driver of a potential
lack of driver attention or drowsi-
ness. It will not steer the vehicle
or prevent loss of control.
. The I–DA system does not detect
and provide an alert of the dri-
ver’s lack of attention or fatigue
in every situation.
. It is the driver’s responsibility to:
— Stay alert.
— Drive safely.
— Keep the vehicle in the travel- ing lane.
— Be in control of the vehicle at all times.
— Avoid driving when tired.
— Avoid distractions (texting, etc). The I–DA system helps alert the driver if
the system detects a lack of attention or
driving fatigue.
The system monitors driving style and
steering behavior over a period of time,
and it detects changes from the normal
pattern. If the system detects that driver
attention is decreasing over a period of
time, the system uses audible and visual
warnings to suggest that the driver take a
break.

mended that you visit a NISSAN dealer for
this service.
WARNING
Failure to follow the warnings and
instructions for proper use of the
RAB system could result in serious
injury or death.
. The RAB system is a supplemen-
tal aid to the driver. It is not a
replacement for proper driving
procedures. Always use the side
and rear mirrors and turn and
look in the direction you will
move before and while backing
up. Never rely solely on the RAB
system. It is the driver’s respon-
sibility to stay alert, drive safely,
and be in control of the vehicle at
all times.
. There is a limitation to the RAB
system capability. The RAB sys-
tem is not effective in all situa-
tions.
The RAB system can assist the driver
when the vehicle is backing up and
approaching objects directly behind the
vehicle.
REAR AUTOMATIC BRAKING (RAB)

5-130Starting and driving
.Never shift the 4WD shift switch
between 4L and 4H while driving.
. Engine idling speed is high while
warming up the engine. Be espe-
cially careful when starting or
driving on slippery surfaces with
the 4WD shift switch in AUTO.

4WD shift indicator
4WD SHIFT INDICATOR
The 4WD shift indicator is displayed in the
vehicle information display.
The indicator should turn off within 1
second after placing the ignition switch
in the ON position.
While the engine is running, the 4WD shift
indicator will illuminate the position se-
lected by the 4WD shift switch. (See the
4WD shift procedure list shown in the
“NISSAN all-mode 4WD® system” (P.5-125).)
.The 4WD shift indicator may blink
while shifting from one drive mode
to the other. When the shifting is
completed, the 4WD shift indicator will come on. If the indicator does
not come on immediately, make
sure the area around the vehicle is
safe, and drive the vehicle straight,
accelerate or decelerate or move the
vehicle in reverse, then shift the 4WD
shift switch.
. If the 4WD warning light comes on, the
4WD shift indicator turns off.
4WD WARNING LIGHT
Warning light Comes on or
blinks when:
Illuminates There is a mal-
function in the 4WD system
Blinks ra- pidly The transfer
case oil tem-
perature is ab- normally high
Blinks slowly The difference
in wheel rota- tion is large
The 4WD warning light is located in the
meter.
The 4WD warning light comes on when
the ignition switch is placed in the ON
position. It turns off soon after the engine
is started.
If any malfunction occurs in the 4WD
system when the ignition switch is placed
in the ON position, the 4WD warning light

will either remain illuminated or blink.
If the 4WD warning light comes on, the
4WD shift indicator turns off.
High-temperature transfer case oil makes
the 4WD warning light blink rapidly (about
twice per second). If the warning light
blinks rapidly during operation, stop the
vehicle in a safe place immediately. Then
if the light turns off after a while, you can
continue driving.
A large difference between the diameters
of front and rear wheels will make the
4WD warning light blink slowly (about
once per two seconds). Change the 4WD
shift switch to AUTO and do not drive fast.
CAUTION
.If the 4WD warning light comes
on or blinks slowly during opera-
tion or rapidly after stopping the
vehicle for a while, have your
vehicle checked as soon as pos-
sible. It is recommended you visit
a NISSAN dealer for this service.
. Shifting between 4HI and 4LO is
not recommended when the 4WD
warning light turns on.
. When the 4WD warning light
comes on, the 2WD mode may be engaged even if the 4WD shift
switch is in AUTO or 4H. Be
especially careful when driving. If
corresponding parts are malfunc-
tioning, the 4WD mode will not be
engaged even if the 4WD shift
switch is shifted.
. Do not drive the vehicle in the 4HI
or 4LO position on dry hard sur-
face roads. Driving on dry, hard
surfaces in 4HI or 4LO may cause
unnecessary noise, tire wear and
increased fuel consumption.
If the 4WD warning light turns on
when driving on dry hard surface
roads:
— in the AUTO or 4HI position,
shift the 4WD shift switch to
AUTO.
— in the 4LO position, stop the vehicle and shift the transmis-
sion shift lever to the N (Neu-
tral) position and shift the
4WD shift switch to AUTO.
. If the 4WD warning light is still on
after the above operation, have
your vehicle checked as soon as
possible. It is recommended you
visit a NISSAN dealer for this
service. .
The transfer case may be da-
maged if you continue driving
with the warning light blinking.

WARNING
.Never rely solely on the hill start
assist system to prevent the ve-
hicle from moving backward on a
hill. Always drive carefully and
attentively. Depress the brake
pedal when the vehicle is stopped
on a steep hill. Be especially care-
ful 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 possi-
ble serious injury or death.
. The hill start assist system is not
designed to hold the vehicle at a
standstill 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 roll-
ing 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 collision or
serious personal injury.
The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the
brake pedal and apply the accelerator
when the vehicle is stopped on a hill.
The hill start assist system will operate
automatically under the following condi-
tions:
. The transmission is shifted to a for-
ward or reverse gear.
. The vehicle is stopped completely on a
hill by applying the brake.
The maximum holding time is 2 seconds.
After 2 seconds the vehicle will begin to
roll back and the hill start assist system
will stop operating completely.
The hill start assist system will not
operate when the transmission is shifted
to the N (Neutral) or P (Park) position or
on a flat and level road.
When the Vehicle Dynamic Control (VDC)
warning light illuminates in the meter, the
hill start assist system will not operate.
(See “Warning lights, indicator lights and
audible reminders” (P.2-10).)

The sonar system sounds a tone to
inform the driver of obstacles near the
bumper.
When the sonar system is turned on, the
sonar view will automatically appear in
the touch screen display when the cam-
era is activated.
WARNING
.The sonar system is a conveni-
ence but it is not a substitute for
proper parking.
. The driver is always responsible
for safety during parking and other maneuvers. Always look
around and check that it is safe
to do so before parking.
. Read and understand the limita-
tions of the sonar system as
contained in this section. The
colors of the sonar indicator in-
dicates different distances to the
object.
. Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may
affect the function of the system;
this may include reduced perfor-

SNOW MODE FRONT AND REAR SONAR SYSTEM
(if so equipped)

— When driving on a steep hill.
SYSTEM TEMPORARILY UNAVAIL-
ABLE
When sonar blockage is detected, the
system will be deactivated automatically.
The system is not available until the
conditions no longer exist.
The sonar sensors may be blocked by
temporary ambient conditions such as
splashing water, mist or fog. The blocked
condition may also be caused by objects
such as ice, frost or dirt obstructing the
sonar sensors.
Action to take:
When the above conditions no longer
exist, the system will resume automati-
cally.
SYSTEM MAINTENANCE
The sonar sensors are located on the
front and rear bumpers. (See “Exterior
front” (P.0-3) and “Exterior rear” (P.0-4).)
.Always keep the area near the sonar
sensors clean.
. If the sonar sensors are dirty, wipe
them off with a soft cloth while being
careful to not damage them.
. The sonar sensors may be blocked by
temporary ambient conditions such as splashing water, mist or fog. The
blocked condition may also be caused
by objects such as ice, frost or dirt
obstructing the sonar sensors. Check
for and remove objects obstructing
the area around the sonar sensors.
. Do not subject the area around the
sonar sensors to strong impact. Also,
do not remove or disassemble the
sonar sensors. If the sonar sensors
and peripheral areas are deformed in
an accident, etc., have the sonar
sensors checked by a NISSAN dealer.
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint on
the sonar sensors and their surround-
ing areas. This may cause a malfunc-
tion or improper operation.
. When washing the vehicle using a
high-pressure washer, do not apply
direct washer pressure on the sonar
sensors. This may cause a malfunction
of the sonar sensors.
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.
The power assisted steering uses a hy-
draulic pump, driven by the engine, to
assist steering.
If the engine stops or the drive belt
breaks, you will still have control of the
vehicle. However, much greater steering
effort is needed, especially in sharp turns
and at low speeds.

POWER STEERING

BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking
force than a conventional 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 de-
vice. It is the driver’s responsibility to
stay alert, drive safely and be in
control of the vehicle at all times.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System
(ABS) is a sophisticated device,
but it cannot prevent accidents
resulting from careless or dan-
gerous driving techniques. It can
help maintain vehicle control dur-
ing braking on slippery surfaces.
Remember that stopping dis-
tances on slippery surfaces will
be longer than on normal sur- faces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire
chains. Always maintain a safe
distance from the vehicle in front
of you. Ultimately, the driver is
responsible for safety.
. Tire type and condition may also
affect 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 Informa-
tion label. See “Tire and load-
ing information label” (P.10-
13).
— For detailed information, see “Wheels and tires” (P.8-28).
The Anti-lock Braking System (ABS) con-
trols 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 prevent each
wheel from locking and sliding. By pre-
venting 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 ABS 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 ABS includes electronic sensors, elec-
tric 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 malfunc-
tion. If the computer senses a malfunc-
tion, it switches the ABS off and
