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.
5-84Starting and driving

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
ahead comes to a stop, the vehicle deceler-
ates to a standstill. However, the ICC system
can only apply up to 40% of the vehicle’s total
braking power. This system should only be
used when traffic conditions allow vehicle
speeds to remain fairly constant or when ve-
hicle speeds change gradually. If a vehicle
moves into the traveling lane ahead or if a
vehicle traveling ahead rapidly decelerates,
the distance between vehicles may become
closer because the ICC system cannot decel-
erate the vehicle quickly enough. If this oc-
curs, the ICC system sounds a warning chime
and blinks the system display to notify the
driver to take necessary action.
The ICC system cancels and a warning chime
sounds if the speed is below approximately
15 mph (25 km/h) and a vehicle is not de-
tected ahead.The ICC system operates as follows:
• When there are no vehicles traveling ahead,
the ICC system maintains the speed set by
the driver. The set speed range is between
approximately 20 and 90 mph (30 and 144
km/h).
• When there is a vehicle traveling ahead, the ICC system adjusts the speed to maintain
the distance, selected by the driver, from
the vehicle ahead. If the vehicle ahead
comes to a stop, the vehicle decelerates to
a standstill. Once your vehicle stops, the
ICC system keeps the vehicle stopped.
• 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 standstill for more than 3 seconds and the vehicle ahead be-
gins to accelerate, push the RES+ switch or
lightly depress the accelerator pedal. The
ICC system starts to follow the vehicle
ahead.
• When the vehicle traveling ahead moves to a different traveling lane, the ICC system
accelerates and maintains vehicle speed up
to the set speed. The ICC system does not control vehicle
speed or warn you when you approach sta-
tionary and slow moving vehicles. You must
pay attention to vehicle operation to main-
tain proper distance from vehicles ahead
when approaching toll gates or traffic
congestion.
Starting and driving5-85

When passing another vehicle, the set speed
indicator
OBflashes when the vehicle speed
exceeds the set speed. The vehicle ahead
detection indicator turns off when the area
ahead of the vehicle is open. When the pedal
is released, the vehicle returns to the previ-
ously set speed. Even though your vehicle
speed is set in the ICC system, you can de-
press the accelerator pedal when it is neces-
sary to accelerate your vehicle rapidly.
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 and set 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).

5-88Starting and driving

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.
WARNING
In order to reduce the risk of a collision that
may result in serious injury or death, please
be aware of the following: •
This function is only activated with the
left turn signal and will briefly accelerate
the vehicle even if a lane change is not
initiated. This can include non-passing
situations such as left side exits.
• Ensure that when passing another ve-
hicle, the adjacent lane is clear before ini-
tiating the pass. Sudden changes in traf-
fic may occur while passing- always
manually steer or brake as needed- never
solely rely on the system.
ICC system limitations
WARNING
Listed below are the system limitations for
the ICC system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death:
• The ICC system is primarily intended for
use on straight, dry, open roads with
light traffic. It is not advisable to use the
ICC system in city traffic or congested
areas. •
The ICC system will not adapt automati-
cally to road conditions. This system
should be used in evenly flowing traffic.
Do not use the system on roads with
sharp curves or on icy roads, in heavy rain
or in fog.
• 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, depending
on the distance to the vehicle ahead and
the surrounding circumstances in order
to maintain a safe distance between
vehicles.
• When the ICC system automatically
brings the car to a stop, your vehicle can
automatically accelerate if the vehicle is
stopped for less than approximately 3
seconds. Be prepared to stop your ve-
hicle if necessary.
Starting and driving5-89

•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 main-
tain the selected distance between ve-
hicles (following distance) or selected
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 con-
ditions:
– On roads with heavy, high-speed
traffic or 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.
• In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert
and avoid using the ICC system where
not recommended in this warning
section.
The ICC system will not detect the following
objects:
• Stationary or 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 radar sensor cannot properly detect a
vehicle ahead and the system may not oper-
ate properly:
• When the sensor detection is reduced (con- ditions such as rain, snow, fog, dust storms,
sandstorms, and road spray from other
vehicles) • Driving on a steep downhill slope or roads
with sharp curves
• Driving on a bumpy road surface, such as an uneven dirt road
• If dirt, ice, snow or other material is cover- ing the radar sensor area
• A complicated-shaped vehicle such as a car carrier trailer or flatbed truck/trailer is near
the vehicle ahead.
• Interference by other radar sources
• When excessively heavy baggage is loaded in the rear seat or cargo area of your
vehicle.
The ICC system is designed to automatically
check the radar sensor’s operation within the
limitations of the system.
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the detec-
tion zone for the ICC system to maintain the
selected distance from the vehicle ahead. A
vehicle ahead may move outside of the de-
tection zone due to its position within the
same lane of travel. Motorcycles may not be
detected in the same lane ahead if they are
traveling offset from the center line of the
lane. A vehicle that is entering the lane ahead
may not be detected until the vehicle has
completely moved into the lane.

tailer for this service.
NOTE:
If the ICC system is temporarily unavailable,
the conventional cruise control mode may
still be used. For additional information, see
“Conventional (fixed speed) cruise control
mode” (P. 5-101).
ICC sensor maintenance
The radar sensor is located on the front of the
vehicle.
To keep the ICC system operating properly,
be sure to observe the following:
• Always keep the sensor area clean.
• Do not strike or damage the areas around
the sensor.
• Do not attach a sticker (including transpar- ent material) or install an accessory near
the sensor. This could cause failure or
malfunction.
• Do not attach metallic objects near the sensor 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.

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.Steering Assist operation
The Steering Assist controls the steering sys-
tem to help keep your vehicle near the center
of the lane when driving. The Steering Assist
is combined with the Intelligent Cruise Con-
trol (ICC) system. For additional information,
see “Intelligent Cruise Control (ICC) (for ve-
hicles with ProPILOT Assist)” (P. 5-84).
The Steering Assist can be activated when
the following conditions are met:
• The ICC system is activated.
• Lane markers on both sides are clearly detected.
• A vehicle ahead is detected (when the ve- hicle is driven at speeds under 37 mph [60
km/h])
• The driver grips the steering wheel.
• The vehicle is driven at the center of the lane.
• The turn signals are not operated.
• The windshield wiper is not operated in the high (HI) speed operation (the steering as-
sist function is disabled after the wiper op-
erates for approximately 10 seconds).

When a curve or strong cross wind exceeds
the capabilities of the Steering Assist and
your vehicle approaches either the left or the
right side of the traveling lane, a warning
chime sounds and the LDP indicator light
(orange) on the instrument panel flashes to
alert the driver. Then, the LDP system auto-
matically applies the brakes for a short period
of time to help assist the driver to return the
vehicle to the center of the traveling lane. This
action is in addition to any Steering Assist
actions.
LSD2990
5-96Starting and driving

Hands on detection
When the Steering Assist is activated, it
monitors the driver’s steering wheel
operation.
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 (1)
appears in the vehicle information display.
If the driver does not operate the steering
wheel after the warning has been displayed,
an audible alert sounds and the warning
flashes in the vehicle information display, fol-
lowed by a quick brake application to request
the driver to take control of the vehicle again.
If the driver still does not respond, the ProPI-
LOT 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 op-
erating the ProPILOT Assist switch.
WARNING
Steering Assist is not a system for a hands-
free driving. Always keep your hands on
the steering wheel and drive your vehicle
safely. Failure to do so could cause a colli-
sion resulting in serious personal injury or
death.
