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 warn-
ing or avoidance device. It is recom-
mended 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.
5-102Starting and driving

•Always drive carefully and atten-
tively when using the ICC system.
Read and understand the Owner’s
Manual thoroughly 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 situa-
tions. Do not use the ICC system ex-
cept 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 decel-
erates the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates 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 condi-
tions allow vehicle speeds to remain fairly
constant or when vehicle speeds change
gradually. If a vehicle moves into the travel-
ing lane ahead or if a vehicle traveling
ahead rapidly decelerates, the distance be-
tween vehicles may become closer be-
cause the ICC system cannot decelerate the vehicle quickly enough. If this occurs,
the ICC system sounds a warning chime
and blinks the system display to notif y the
driver to take necessary action.
The ICC system cancels and a warning
chime sounds if the speed is below ap-
proximately 15 mph (24 km/h) and a vehicle
is not detected 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 (32 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 ve-
hicle ahead comes to a stop, the vehicle
decelerates to a standstill. Once your ve-
hicle stops, the ICC system keeps the ve-
hicle 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 begins to accelerate, push the
RES+ switch or lightly depress the accel-
erator pedal. The ICC system starts to
follow the vehicle ahead.
• When the vehicle traveling ahead moves to a different traveling lane, the ICC sys-
tem accelerates and maintains vehicle
speed up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow-moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead when approaching toll gates or traf-
fic congestion.
Starting and driving5-103

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system adjusts the speed to
maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway,
the ICC system accelerates and maintains
the speed up to the set speed. Pay atten-
tion to the driving operation to maintain
control of the vehicle as it accelerates to
the set speed.
The vehicle may not maintain the set
speed on winding or hilly roads. If this oc-
curs, you will have to manually control the
vehicle speed.Normally when controlling the distance to
a vehicle ahead, the system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is re-
quired for a lane change. Depress the brake
pedal when deceleration is required to
maintain a safe distance to the vehicle
ahead due to sudden braking or if a vehicle
cuts in. Always stay alert when using the
ICC system.
No vehicle detected ahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem maintains the set vehicle speed, simi-
lar to standard cruise control, as long as no
vehicle is detected in the lane ahead. The
ICC system displays the set speed.

5-104Starting and driving

Vehicle detected ahead
When a vehicle is detected in the lane
ahead, the ICC system decelerates the ve-
hicle by controlling the throttle and apply-
ing the brakes to match the speed of a
slower vehicle ahead. The ICC system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.
NOTE:
• The stop lights of the vehicle come onwhen braking is performed by the ICC
system.
• When the brake is applied by the sys- tem, a noise may be heard. This is not a
malfunction.
When the ICC system detects a vehicle
ahead, the vehicle ahead detection indica-
tor and the speed control status indicator
(distance control mode) illuminates (solid
green
).
Vehicle ahead stops
When the vehicle ahead decelerates to
stop, your vehicle decelerates to a stand-
still. Once your vehicle stops, the ICC sys-
tem automatically applies the brakes to
keep the vehicle stopped. When your ve-
hicle is at a standstill, the “(RES+) Press to
start” message is displayed on the vehicle
information display.
NOTE:
When your vehicle stops for less than 3
seconds, your vehicle will automatically
follow the vehicle as it accelerates from a
stop. Vehicle ahead accelerates
When your vehicle is stopped and the ve-
hicle ahead begins to accelerate, push the
RES+ switch or lightly depress the accelera-
tor pedal. The ICC system starts to follow
the vehicle ahead.
Vehicle ahead not detected
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.
When a vehicle is no longer detected, the
vehicle ahead detection indicator turns off
and the speed control status indicator
(maintain speed control mode) illuminates
(green outline
).
The ICC system gradually accelerates to
the set speed, but you can depress the
accelerator pedal to quickly accelerate.
When a vehicle is no longer detected and
your vehicle is traveling under approxi-
mately 15 mph (24 km/h), the ICC system
automatically cancels.

Starting and driving5-105

When passing another vehicle, the set
speed indicator
OBflashes when the ve-
hicle speed exceeds the set speed. The ve-
hicle ahead detection indicator turns off
when the area ahead of the vehicle is open.
When the pedal is released, the vehicle re-
turns to the previously set speed. Even
though your vehicle speed is set in the ICC
system, you can depress the accelerator
pedal when it is necessary to accelerate
your vehicle rapidly.
Cut-in detection
If a vehicle moves into your traveling lane
near your vehicle, the ICC system may in-
form the driver by flashing the vehicle
ahead detection 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 sys-
tem warns the driver with the chime and
ICC system display. Decelerate by depress-
ing the brake pedal to maintain a safe ve-
hicle distance 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 vehicle or on the side of the
road. This may cause the ICC system to
decelerate or accelerate the vehicle. The
radar sensor may detect 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 control
the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be af-
fected by vehicle operation (steering
maneuver or driving position in the lane)
or traffic or vehicle conditions (for ex-
ample, if a vehicle is being driven with
some damage).
LSD2895
5-106Starting and driving

Acceleration when passing
When the ICC system is engaged above 43
mph and following a slower vehicle (below
ICC set speed), and the turn signal is acti-
vated to the lef t, the ICC system will auto-
matically start to accelerate the vehicle to
help initiate passing on the lef t and will
begin to reduce the distance to the vehicle
directly ahead. Only the lef t 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 continue to accelerate to the
ICC system set speed. If another vehicle is
detected ahead, then the vehicle will accel-
erate up to the following speed of that ve-
hicle. If the vehicle is not steered into the
lef t lane to pass, the acceleration will stop
af ter a short time and regain the set follow-
ing distance. Acceleration can be stopped
at any point by depressing 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 lef t turn signal and will briefly ac-
celerate the vehicle even if a lane
change is not initiated. This can in-
clude non-passing situations such as
lef t side exits.
• Ensure that when passing another
vehicle, the adjacent lane is clear be-
fore initiating the pass. Sudden
changes in traffic 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 vehicle in accordance with these
system limitations could result in seri-
ous 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 auto-
matically 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 over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the
brake pedal, depending on the dis-
tance 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 ap-
proximately 3 seconds. Be prepared
to stop your vehicle if necessary.
Starting and driving5-107

•Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The ICC system may not
be able to maintain the selected dis-
tance between vehicles (following
distance) or selected vehicle speed
under some circumstances.
• The system may not detect the ve-
hicle in front of you in certain road or
weather conditions. To avoid acci-
dents, never use the ICC system un-
der the following conditions:
– 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 ve-
hicle may go beyond the set ve-
hicle speed and frequent braking
may result in overheating the
brakes)
– On repeated uphill and downhill
roads –
When traffic conditions make it
difficult to keep a proper distance
between vehicles because of fre-
quent acceleration or
deceleration
–
Interference by other radar sources
• In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Al-
ways 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 op-
erate properly:
• When the sensor detection is reduced (conditions 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 automati-
cally 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 de-
tection zone for the ICC system to maintain
the selected distance from the vehicle
ahead. A vehicle ahead may move outside
of the detection 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 en-
tering the lane ahead may not be detected
until the vehicle has completely moved into
the lane.
5-108Starting and driving

If this occurs, the ICC system may warn you
by blinking the system indicator and
sounding the chime. The driver may have
to manually control the proper distance
away from the vehicle traveling ahead.
The ICC system (with ProPILOT Assist) uses
a multi-sensing front camera. The follow-
ing are some conditions in which the cam-
era may not properly detect a vehicle and
detection of a vehicle ahead may be
delayed:
• Poor visibility (conditions such as rain,snow, fog, dust storms, sandstorms, and
road spray from other vehicles)
• The camera area of the windshield is fogged up or covered with dirt, water
drops, ice, snow, etc.
• Strong light (for example, sunlight or high beams from oncoming vehicles) enters
the front camera
• A sudden change in brightness occurs (for example, when the vehicle enters or
exits a tunnel or shaded area or lightning
flashes)
LSD2898
Starting and driving5-109

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar
sensor may detect vehicles in a different
lane, or may temporarily not detect a ve-
hicle 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 ma-
neuver 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 sound-
ing 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 unavail-
able. In these instances, the ICC system
may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead.Condition A
