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 control
mode: For cruising at a preset speed
NOTE:Steering assist is not available in the conven-
tional (fixed speed) cruise control mode.
•Vehicle-to-vehicle distance control mode:
The ICC system maintains a selected dis-
tance 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 (30 to 144 km/h). When the ve-
hicle ahead slows to a stop, your vehicle
gradually decelerates to a standstill. When
the vehicle is stopped, the ICC system
maintains braking force to keep your ve-
hicle 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 ve-
hicle ahead begins to accelerate,
push the RES+ switch or lightly de-
press the accelerator pedal. The ICC
system starts to follow the vehicle
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 (30 km/h) to use this func-
tion.
NOTE:Even if the Forward Emergency Braking
with Pedestrian Detection setting is turned
off by the driver using the “Driver Assis-
tance” menu in the lower display, Forward
Emergency Braking 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 vehicle
within the traveling lane.
When there is no vehicle ahead, Steering
Assist is not available at speeds under 37
mph (60 km/h).ProPILOT Assist switches

INTELLIGENT CRUISE CONTROL
(ICC) (for vehicles with ProPILOT
Assist)
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the ICC system
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 recommended for
highway use only and it is not intended
for city driving. It is the driver’s respon-
sibility to stay alert, drive safely, and be
in control of the vehicle at all times. •
There are limitations to the ICC system
capability. The ICC system does not
function in all driving, traffic, weather,
and road conditions. It is the driver’s re-
sponsibility 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.
• Always drive carefully and attentively
when using the ICC system. Read and
understand the Owner’s Manual thor-
oughly before using the ICC system. To
avoid serious injury or death, do not rely
on the system to prevent accidents or to
control the vehicle’s speed in emergency
situations. Do not use the ICC system
except in appropriate road and traffic
conditions.
ICC system operation
The ICC system is designed to maintain a
selected distance from the vehicle in front of
you and can reduce the speed to match a
slower vehicle ahead. The system decelerates
the vehicle as necessary and if the vehicle
Starting and driving5-87

Cut-in detection
If a vehicle moves into your traveling lane
near your vehicle, the ICC system may inform
the driver by flashing the vehicle ahead de-
tection indicator.
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the system
warns the driver with the chime and ICC sys-
tem display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:
• The chime sounds.
• The vehicle ahead detection indicator andset distance indicator blink.
• You judge it necessary to maintain a safe distance.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are:
• When the vehicles are traveling at the same speed and the distance between vehicles is
not changing. • When the vehicle ahead is traveling faster
and the distance between vehicles is
increasing.
• When a vehicle cuts in near your vehicle.
The warning chime will not sound when:
• Your vehicle approaches other vehicles that are parked or moving slowly.
• The accelerator pedal is depressed, over- riding the system.
NOTE:
The approach warning chime may sound and
the system display may flash when the radar
sensor detects objects on the side of the ve-
hicle or on the side of the road. This may
cause the ICC system to decelerate or accel-
erate the vehicle. The radar sensor may de-
tect these objects when the vehicle is driven
on winding, narrow, or hilly roads or when
the vehicle is entering or exiting a curve. In
these cases, you will have to manually con-
trol the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or ve-
hicle conditions (for example, if a vehicle is
being driven with some damage).
Acceleration when passing
When the ICC system is engaged above 44
mph and following a slower vehicle (below
ICC set speed), and the turn signal is acti-
vated to the left, the ICC system will auto-
matically start to accelerate the vehicle to
help initiate passing on the left and will begin
to reduce the distance to vehicle directly
ahead. Only the left side turn signal operates
this feature. As the driver steers the vehicle
and moves into the passing lane, if no vehicle
is detected ahead the ICC system will con-
tinue to accelerate to the ICC system set
speed. If another vehicle is detected ahead,
then the vehicle will accelerate up to the fol-
lowing speed of that vehicle. If the vehicle is
not steered into the left lane to pass, the
acceleration will stop after a short time and
regain the set following distance. Accelera-
tion can be stopped at any point by depress-
ing the brake pedal or the CANCEL switch on
the steering wheel.
Starting and driving5-91

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar sen-
sor may detect vehicles in a different lane, or
may temporarily not detect a vehicle traveling
ahead. This may cause the radar system to
decelerate or accelerate the vehicle.
The detection of vehicles may also be af-
fected by vehicle operation (steering maneu-
ver or traveling position in the lane, etc.) or
vehicle condition.If this occurs, the ICC system may warn you
by blinking the system indicator and sounding
the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.
Automatic cancellation
The following are conditions in which the ICC
system may be temporarily unavailable. In
these instances, the ICC system may not can-
cel and may not be able to maintain the se-
lected following distance from the vehicle
ahead.Condition A
Under the following conditions, the ICC sys-
tem is automatically canceled. A chime will
sound and the system will not be able to be
set:
• Any door is open.
• The driver’s seat belt is not fastened.
• The vehicle ahead is not detected and your
vehicle is traveling below the speed of 15
mph (25 km/h).
• Your vehicle has been stopped by the ICC system for approximately 3 minutes or
longer.
• The shift lever is not in the D (Drive) position or manual shift mode.
• The electronic parking brake is applied.
• The VDC system is turned off.
• The Forward Emergency Braking with Pe- destrian Detection applies harder braking.
• VDC (including the traction control system) operates.
• A wheel slips.
• When distance measurement becomes im- paired due to adhesion of dirt or obstruc-
tion to the sensor.
• When the radar signal is temporarily interrupted.

• Do not attach metallic objects near thesensor area (brush guard, etc.). This could
cause failure or malfunction.
• Do not alter, remove, or paint the front bumper.
Before customizing or restoring the front
bumper, it is recommended that you visit an
INFINITI retailer.
The camera sensor is located above the in-
side mirror.
To keep the proper operation of the systems
and prevent a system malfunction, be sure to
observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar- ent material) or install an accessory near
the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely 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 an
INFINITI retailer.
STEERING ASSIST
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the Steering Assist
could result in serious injury or death.
• The Steering Assist is not a replacement
for proper driving procedures and is not
designed to correct careless, inattentive
or absent-minded driving. The Steering
Assist will not always steer the vehicle to
keep it in the lane. It is not designed to
prevent loss of control. 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.
• As there is a performance limit to the
Steering Assist’s capability, never rely
solely on the system. The Steering Assist
does not function in all driving, traffic,
weather, and road conditions. Always
drive safely, pay attention to the opera-
tion of the vehicle, and manually control
your vehicle appropriately. •
The Steering Assist is intended for use on
well-developed freeways or highways
with gentle (moderate) curves. To avoid
risk of an accident, do not use this system
on local or non-highway roads.
• The Steering Assist only steers the ve-
hicle to maintain its position in the center
of a lane. The vehicle will not steer to
avoid objects in the road in front of the
vehicle or to avoid a vehicle moving into
your lane.
• 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. Never take your
hands off the steering wheel when driv-
ing. Always keep your hands on the
steering wheel and drive your vehicle
safely.
• Always drive carefully and attentively
when using the Steering Assist. Read
and understand the Owner’s Manual
thoroughly before using the Steering As-
sist. To avoid serious injury or death, do
not rely on the system to prevent acci-
dents or to control the vehicle’s speed in
emergency situations. Do not use the
Steering Assist except in appropriate
road and traffic conditions.
