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 responsi-
bility 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 func-
tion in all driving, traffic, weather, and
road conditions. It is the driver’s respon-
sibility 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 un-
derstand 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 ex-
cept in appropriate road and traffic
conditions.
5-118Starting 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 (24 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 (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 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 con-
gestion.
Starting and driving5-119

Vehicle detected ahead
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by
controlling the throttle and applying the
brakes to match the speed of a slower vehicle
ahead. The ICC system then controls the ve-
hicle speed based on the speed of the vehicle
ahead to maintain the driver selected dis-
tance.
NOTE:∙ The stop lights of the vehicle come on
when braking is performed by the ICC
system. ∙
When the brake is applied by the system,
a noise may be heard. This is not a mal-
function.
When the ICC system detects a vehicle
ahead, the vehicle ahead detection indicator
and the speed control status indicator (dis-
tance control mode) illuminates (solid
green
).
Vehicle ahead stops
When the vehicle ahead decelerates to stop,
your vehicle decelerates to a standstill within
the system capability. Once your vehicle
stops, the ICC system automatically applies
the brakes to keep the vehicle stopped. When
your vehicle 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 sec-
onds, your vehicle will automatically follow
the vehicle as it accelerates from a stop.
Vehicle ahead accelerates
When your vehicle is stopped and the vehicle
ahead begins to accelerate, push the RES+
switch or lightly depress the accelerator
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 accelerates 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 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 accelera-
tor pedal to quickly accelerate. When a ve-
hicle is no longer detected and your vehicle is
traveling under approximately 15 mph
(24 km/h), the ICC system automatically can-
cels.

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 foruse 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 dis-
tance control function, never rely solely
on the ICC system. This system does not
correct careless, inattentive or absent-
minded driving or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding circumstances in order to main-
tain 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.
∙ Always pay attention to the operation of the vehicle and be ready to manually con-
trol the proper following distance. The
ICC system may not be able to maintain
the selected distance between vehicles
(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
conditions: – On roads with heavy, high-speed traf-
fic 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.
∙ Do not use the ICC system if you are tow- ing a trailer. The system may not detect a
vehicle ahead.
Starting and driving5-123

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.
