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 50% of the vehicle’s total braking
power. This system should only be used when
traffic conditions allow vehicle speeds to re-
main fairly constant or when vehicle speeds
change gradually. If a vehicle moves into the
traveling lane ahead or if a vehicle traveling
ahead rapidly decelerates, the distance be-
tween vehicles may become closer because
the ICC system cannot decelerate the vehicle
quickly enough. If this occurs, the ICC system
will sound a warning chime and illuminate the
distance warning light to notify the driver to
take necessary action.
The following items are controlled in the ICC
system:
•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
125 MPH (30 and 200 km/h).
•When there is a vehicle traveling ahead,
the ICC system adjusts the speed to main-
tain the distance, selected by driver, from
the vehicle ahead. The adjusting speed
range is up to the set speed. If the vehicle
ahead comes to a stop, the vehicle decel-
erates to a standstill within the limitations
of the system. Once the vehicle is station-
ary, it remains stationary and you do not
need to depress the brake pedal.
•When the vehicle traveling ahead has
moved out from its lane of travel, pull the
cruise control lever or push the accelerator
pedal briefly. 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 con-
gestion.

OPERATING ICC
To set cruising speed, accelerate your vehicle
to the desired speed and quickly push the
cruise control lever, up
1or down4. Take
your foot off the accelerator pedal. Your ve-
hicle will maintain the set speed.
NOTE
If you do not fully release the accelerator
pedal, the [ICC Suspended] message ap-
pears in the vehicle information display. The
set distance to a slower-moving vehicle in
front will then not be maintained. You will be
driving at the speed you determine by the
position of the accelerator pedal.
You can also activate the ICC when station-
ary. The lowest speed that can be set is
20 MPH (30 km/h ).
System operation
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 for 5 seconds after the
cruise control lever is activated.
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 system then controls the vehicle
speed based on the speed of the vehicle
ahead to maintain the driver selected dis-
tance.The brake lights of the vehicle come on when
braking is performed by the ICC system.
When the brake operates, a noise may be
heard. This is not a malfunction.
When a vehicle ahead is detected, the vehicle
ahead symbol
1appears in the vehicle infor-
mation display.
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 display turns off

If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system con-
trols the distance to that vehicle.
Changing lanes to pass another
vehicle:
When you changes lane to pass another ve-
hicle, ICC supports the action if:
•The vehicle speed is more than 45 MPH
(70 km/h)
•The ICC is maintaining the distance to a
vehicle in front
•The respective turn signal is activated
If these conditions are met, the vehicle will be
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the
distance between your vehicle and the ve-
hicle in front becomes too small.
How to change the set vehicle
speed
To cancel the preset speed, use any of these
methods:
•Tap the brake pedal when the vehicle is
moving.
•Quickly push the cruise control lever in the
direction of arrow
5.
The message [ICC OFF] appears in the ve-
hicle information display for 5 seconds.
To reset at a higher cruising speed, use one of
the following methods:
•Depress the accelerator pedal. When the
vehicle attains the desired speed, quickly
pull the cruise control lever towards you
3.
•Pull the cruise control lever up1beyond
the pressure point. The set vehicle speed
will increase by approximately 10 MPH
(10 km/h).
•Pull the cruise control lever up (1) at the
pressure point. The set vehicle speed will
increase by approximately 1 MPH (1 km/h).
To reset at a lower cruising speed, use one of
the following methods:
•Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, quickly pull
the cruise control lever towards you
3.
•Pull the cruise control lever down4be-
yond the pressure point. The set vehicle
speed will decrease by approximately
10 MPH (10 km/h).
•Pull the cruise control lever down4to the
pressure point. The set vehicle speed will
decrease by approximately 1 MPH (1 km/h).
To resume the preset speed, quickly pull the
cruise control lever towards you
4. The ve-
hicle will resume the last set cruising speed
when the vehicle speed is over 20 MPH
(30 km/h).
NOTE
If you do not fully release the accelerator
pedal, the [ICC Deactivated Automatically]
message appears in the vehicle information

display. The set distance to a slower-moving
vehicle in front will then not be maintained.
You will be driving at the speed you deter-
mine by the position of the accelerator pedal.
You can also activate ICC when stationary.
The lowest speed that can be set is 20 MPH
(30 km/h).
Stopping
WARNING
•To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others, or pets unattended in
your vehicle.
•The ICC system should only be used to
keep the vehicle stationary when the
driver is actively using the system.
When parking the vehicle, make sure to
turn OFF the ICC system, use the brake,
press the PARK (P) button, and place
the ignition switch in the LOCK position
prior to exiting the vehicle. Failure to do
so could lead to serious injury or death.
The ICC system will not hold the vehiclein place after coming to a stop when any
of the following conditions occur:
–There is a malfunction in the system
or in the voltage supply.
–The ICC system has been deactivated
with the cruise control lever, e. g. by a
vehicle occupant.
–The accelerator pedal has been de-
pressed, e.g. by a vehicle occupant.
For further information on deactivating the
ICC system, see "ICC switch (cruise control
lever)" earlier in this section
If the ICC system detects that the vehicle in
front is stopping, it brakes your vehicle until it
is stationary (within the braking limitations of
the system).
Once your vehicle is stationary, it remains
stationary and you do not need to depress
the brake.
NOTE
Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever.
How to change the set distance to
the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traffic
conditions.
To increase the distance to the vehicle ahead,
turn the knob
3toward the rear2.To
decrease the distance to the vehicle ahead,
turn the knob
3toward the front1.
You can see this distance in the vehicle infor-
mation display.
The distance to the vehicle ahead will change
according to the vehicle speed. The higher the
vehicle speed, the longer the distance.

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 distance
warning light. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:
•The chime sounds.
•The distance warning light is illuminated.
The warning chime may not sound and the
distance warning light may not illuminate 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 ve-
hicles is not changing. In this case, the
distance warning light will be on.
•When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing.
•When a vehicle cuts in near your vehicle
•The warning chime will not sound and the
distance warning light will not illuminate
when:
– The vehicle approaches other vehicles
that are parked or moving slowly.– The accelerator pedal is depressed,
overriding the system.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driv-
ing position in the lane) or traffic or vehicle
condition (for example, if a vehicle is being
driven with some damage).
Automatic cancellation
A chime sounds and the message [ICC off] is
displayed in the vehicle information display
for 5 seconds under the following conditions
and the control is automatically canceled.
•The electric parking brake is applied.
•The VDC intervenes or the VDC is deacti-
vated.
•The P (Park), R (Reverse) or N (Neutral)
position is engaged.
•The cruise control lever is pulled in order to
pull away but the front passenger door or
one of the rear doors is open.
•The vehicle is skidding or a wheel slips.
•Active Park Assist is activated.
ICC 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.
•This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’s re-
sponsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
•The system is primarily intended for use
on straight, dry, open roads with light
traffic. It is not advisable to use the sys-
tem in city traffic or congested areas.
•This 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.
5-56Starting and driving

•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
absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed
by depressing the brake pedal, depend-
ing on the distance to the vehicle ahead
and the surrounding circumstances in
order to maintain a safe distance be-
tween vehicles.
•If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. Once the
vehicle is stationary, it remains station-
ary and you do not need to depress the
brake pedal.
•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.
•Normally when controlling the distance
to a vehicle ahead, this system auto-
matically accelerates or deceleratesyour vehicle according to the speed of
the vehicle ahead. If required, depress
the accelerator to properly accelerate
your vehicle when acceleration is re-
quired for a lane change. Depress the
brake pedal when deceleration is re-
quired to maintain a safe distance to the
vehicle ahead due to its sudden braking
or if a vehicle cuts in. Always stay alert
when using the ICC system.
•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 where the traffic is heavy or
there are 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
system 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.
–If there is interference by other radar
sources.
•Do not use the ICC system if you are
towing a trailer. The system may not de-
tect a vehicle ahead.
•In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to
control the distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the ICC system
when it is not recommended in this sec-
tion.
•The distance sensor will not detect the
following objects:
–Stationary and slow moving vehicles.
–Pedestrians or objects in the road-
way.
–Oncoming vehicles in the same lane.
–Motorcycles traveling offset in the
travel lane.
Starting and driving5-57

The following are some conditions in which the
sensor cannot properly detect a vehicle ahead
and the system may not operate properly:
•When the snow or road spray from travel-
ing vehicles reduces the sensor’s visibility.
•When excessively heavy baggage is
loaded in the rear seat or the luggage room
of your vehicle.
The ICC system is designed to automatically
check the sensor’s operation within the limi-
tation of the system. When the sensor is cov-
ered with dirt or is obstructed, the system will
automatically be canceled. If the sensor is
covered with ice, a transparent or translucent
vinyl bag, etc., the ICC system may not detect
them. In these instances, the ICC system may
not cancel and may not be able to maintain
the selected following distance from the ve-
hicle ahead. Be sure to check and clean the
sensor regularly.
TIPS FOR DRIVING WITH THE ICC
SYSTEM
General notes
The following contains descriptions of cer-
tain road and traffic conditions in which you
must be particularly attentive. In such situa-
tions, brake if necessary. The ICC system is
then deactivated
Cornering, entering and exiting a
bend
The ability of the ICC system to detect ve-
hicles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles that are not driving in the
middle of their lane
The ICC system may not detect vehicles
which are not driving in the middle of their
lane. The system will not brake for or keep a
following distance to the car which is offset.
