4ProPILOT Assist switch
The ProPILOT Assist system has the follow-
ing two functions:
1. Intelligent Cruise Control (ICC)
The ICC system can be set to one of two
cruise control modes:
• Conventional (fixed speed) cruise con-
trol mode: For cruising at a preset speed
NOTE:Steering Assist is not available in the
conventional (fixed speed) cruise control
mode.
•Vehicle-to-vehicle distance control
mode: The ICC system maintains a se-
lected distance from the vehicle in front
of you within the speed range of 0 to 90
mph (0 to 144 km/h) up to the set speed.
The set speed can be selected by the
driver between 20 to 90 mph (32 to 144
km/h). When the vehicle ahead slows to a
stop, your vehicle gradually decelerates
to a standstill. When the vehicle is
stopped, the ICC system maintains brak-
ing force to keep your vehicle stopped.

NOTE:When your vehicle is stopped for less
than 3 seconds and the vehicle ahead
begins to move, your vehicle will start
moving again automatically.– When your vehicle is at a standstillfor more than 3 seconds and the
vehicle ahead begins to accelerate,
push the RES+ switch or lightly de-
press the accelerator pedal. The
ICC system starts to follow the ve-
hicle ahead.
– When no vehicle is detected ahead within the driver selected distance,
the vehicle travels at the speed set
by the driver. The speed must be
above 20 mph (32 km/h) to use this
function.
NOTE:Even if the Automatic Emergency Brak-
ing (AEB) with Pedestrian Detection set-
ting is turned off by the driver using the
“Settings” menu in the vehicle informa-
tion display, AEB with Pedestrian Detec-
tion will be automatically turned on
when ICC is used. 2.
Steering Assist
The Steering Assist function controls the
steering system to help keep your ve-
hicle within the traveling lane.
When there is no vehicle ahead, Steering
Assist is not available at speeds under 37
mph (60 km/h).

INTELLIGENT CRUISE CONTROL
(ICC) (for vehicles with ProPILOT
Assist)
WARNING
Failure to follow the warnings and in-
structions for proper use of the ICC sys-
tem could result in serious injury or
death. •
The ICC system is only an aid to assist
the driver and is not a collision
warning or avoidance device. It is rec-
ommended for highway use only and
it is not intended for city driving. It is
the driver’s responsibility to stay
alert, drive safely, and be in control of
the vehicle at all times.
• There are limitations to the ICC sys-
tem capability. The ICC system does
not function in all driving, traffic,
weather, and road conditions. It is the
driver’s responsibility to stay alert,
drive safely, keep the vehicle in the
traveling lane, and be in control of the
vehicle at all times.
• Always observe posted speed limits
and do not set the speed over them.
• The ICC system does not react to sta-
tionary and slow moving vehicles.
5-106Starting and driving

If the steering wheel is not operated or the
driver takes his/her hands off the steering
wheel for a period of time, the warning
O1
appears in the vehicle information display.
If the driver does not operate the steering
wheel af ter the warning has been dis-
played, an audible alert sounds and the
warning flashes in the vehicle information
display, followed by a quick brake applica-
tion to request the driver to take control of
the vehicle again.
If the driver still does not respond, the Pro-
PILOT Assist turns on the hazard flasher
and slows the vehicle to a complete stop.
The driver can cancel the deceleration at
any time by steering, braking, accelerating,
or operating the ProPILOT Assist switch.
WARNING
Steering Assist is not a system for
hands-free driving. Always keep your
hands on the steering wheel and drive
your vehicle safely. Failure to do so
could cause a collision resulting in seri-
ous personal injury or death.
NOTE:
If the driver lightly touches (instead of
firmly grips) the steering wheel, the
steering torque sensor may not detect
the driver’s hand(s) on the wheel and a
sequence of warnings may occur. When
the driver holds and operates the steer-
ing wheel again, the warnings turn off.
Steering Assist limitations
WARNING
• In the following situations, the cam-
era may not detect lane markers cor-
rectly or may detect lane markers in-
correctly and the Steering Assist may
not operate properly:
– When driving on roads where
there are multiple parallel lane
markers, lane markers that are
faded or not painted clearly, non-
standard lane markers, or lane
markers covered with water, dirt,
snow, etc.
– When driving on roads with dis-
continued lane markers
– When driving on roads with a wid-
ening or narrowing lane width –
When driving on roads where
there are multiple lanes or unclear
lane markers due to road
construction
– When driving on roads where
there are sharply contrasting ob-
jects, such as shadows, snow, wa-
ter, wheel ruts, seams, or lines re-
maining af ter road repairs (the
Steering Assist could detect these
items as lane markers)
– When driving on roads where the
traveling lane merges or
separates
• Do not use the Steering Assist under
the following conditions because the
system may not properly detect lane
markers. Doing so could cause a loss
of vehicle control and result in an ac-
cident.
– During bad weather (rain, fog,
snow, dust, etc.)
– When rain, snow, sand, etc., is
thrown up by the wheels of other
vehicles
– When dirt, oil, ice, snow, water, or
another object adheres to the
camera unit
5-120Starting and driving

Automatic standby:
In the following cases, a warning message
is displayed along with the chime, and the
Steering Assist is placed in a temporary
standby mode. (The Steering Assist re-
starts automatically when the operating
conditions are met again.)
• When lane markers on both sides are nolonger detected
• When a vehicle ahead is no longer de- tected under approximately 37 mph (60
km/h)
Steering Assist cancel
Under the following conditions, the Steer-
ing Assist cancels, and the Steering Assist
status indicator and the Steering Assist in-
dicator turn off:
• When unusual lane markers appear inthe traveling lane or when the lane
marker cannot be correctly detected for
some time due to certain conditions (for
example, a snow rut, the reflection of light
on a rainy day, the presence of several
unclear lane markers) • When the windshield wiper operates in
the high (HI) speed operation (the Steer-
ing Assist is disabled when the wiper op-
erates for more than approximately 10
seconds)
Action to take:
Turn the ICC system off using the CANCEL
switch. When the conditions listed above
are no longer present, turn the ICC system
on again.
Steering Assist malfunction
When the system malfunctions, it turns off
automatically. The Steering Assist status
warning illuminates (orange). A chime may
sound depending on the situation.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off, restart the engine, resume driving,
and set the Intelligent Cruise Control sys-
tem again. If the warning (orange) contin-
ues to illuminate, the Steering Assist is mal-
functioning. Although the vehicle is still
drivable under normal conditions, have the
system checked. It is recommended that
you visit a NISSAN dealer for this service.
Steering Assist maintenance
The camera sensor is located above the
inside mirror.
To keep the proper operation of the system
and prevent a system malfunction, be sure
to observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including trans- parent material) or install an accessory
near the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the
camera lens or remove the screw located
on the camera unit.
If the camera unit is damaged due to an
accident, it is recommended that you visit a
NISSAN dealer.
5-122Starting and driving

•HEADED UPHILL WITH CURBOB:
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
OC:
Turn the wheels toward the side of the
road so the vehicle will move away
from the center of the road if it moves.
4. Place the ignition switch in the LOCK position.
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 run-
ning, there will be no power assist for
the steering. You will still have control
of the vehicle, but the steering will be
much harder to operate. Have the
power steering system checked. It is
recommended that you visit a
NISSAN dealer for this service.
The power steering system is designed to
provide power assistance while driving to
operate the steering wheel with light force.
When the steering wheel is operated re-
peatedly or continuously while parking or
driving at a very low speed, the power as-
sist for the steering wheel will be reduced.
This is to prevent overheating of the power
steering system and protect it from getting
damaged. While the power assist is re-
duced, steering wheel operation will be-
come heavy. If the steering wheel opera-
tion is still performed, the power steering
may stop and the power steering warning
light will illuminate. In a safe location, stop the engine and place the ignition switch in
the OFF position. The temperature of the
power steering system will go down af ter a
period of time and the power assist level
will return to normal af ter starting the en-
gine. The power steering warning light will
go off. Avoid repeating such steering wheel
operations that could cause the power
steering system to overheat.
You may hear a noise from the front of the
vehicle when the steering wheel is oper-
ated. This is a normal operational noise
and is not a malfunction.
If the 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 servic-
ing. Have the power steering system
checked. It is recommended that you visit a
NISSAN dealer for this service.
When the power steering warning light illu-
minates with the engine running, the
power assist for the steering will cease op-
eration but you will still have control of the
vehicle. At this time, greater steering efforts
are required to operate the steering wheel,
especially in sharp turns and at low speeds.
POWER STEERING
5-172Starting 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.
