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

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. 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 attention 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 occurs, you
will have to manually control the vehicle
speed.
SSD0254
5-88Starting and driving

Normally when controlling the distance to a
vehicle ahead, the system automatically ac-
celerates or decelerates your vehicle accord-
ing to the speed of the vehicle ahead.
Depress the accelerator to properly acceler-
ate your vehicle when acceleration is required
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, similar to
standard cruise control, as long as no vehicle
is detected in the lane ahead. The ICC system
displays the set speed.
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
distance.
NOTE:
• The stop lights of the vehicle come onwhen braking is performed by the ICC
system.

• When the brake is applied by the system, anoise may be heard. This is not a
malfunction.
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 out-
line
).
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 (25
km/h), the ICC system automatically cancels. 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.

5-90Starting and driving

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.
