The Intelligent Cruise Control (ICC) system
automatically maintains a selected dis-
tance from the vehicle traveling in front of
you according to that vehicle ’ s speed (up
to the set speed), or at the set speed when
the road ahead is clear.
The ICC function can be set to one of two
cruise control modes:
. Vehicle-to-vehicle distance control
mode:
For maintaining a selected distance
between your vehicle and the vehicle
in front of you up to the preset speed.
. Conventional (fixed speed) cruise con-
trol mode:
For cruising at a preset speed.
WARNING . Always drive carefully and attentively
when using either cruise control mode.
Read and understand the Owner ’ s Man-
ual thoroughly before using the cruise
control. 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 cruise control except in appropriate
road and traffic conditions.

CONTROL MODE GUID-F26546BD-2614-46CC-AB79-47EFE2220077
In the vehicle-to-vehicle distance control
mode, the Intelligent Cruise Control (ICC)
system automatically maintains a selected
distance from the vehicle traveling in front
of you according to that vehicle ’ s speed
(up to the set speed), or at the set speed
when the road ahead is clear.
With ICC, the driver can maintain the same
speed as other vehicles without the con-
stant need to adjust the set speed as you
would with a normal cruise control system. SSD0926

The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the distance sensor
* A
detects a slower
moving vehicle ahead, the system will
reduce the vehicle speed so that your
vehicle follows the vehicle in front at the
selected distance.
The system automatically controls the
throttle and applies the brakes (up to
25% of vehicle braking power) if neces-

The detection range of the sensor is
approximately 390 ft (120 m) ahead.
WARNING. This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver ’ s
responsibility 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
system in city traffic or congested areas.
. This system will not adapt automatically
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.
The distance sensor will not detect under
most conditions:
. Stationary and slow moving vehicles
. Pedestrians or objects in the roadway . Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
This system will not automatically brake
the vehicle to a stop.
WARNING . As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain a
safe distance between vehicles.
. Although the brake operation is con-
trolled by the system, the system does
not automatically stop the vehicle. If the
vehicle speed falls below approximately
20 MPH (32 km/h), the Intelligent Cruise
Control system is automatically canceled
and a warning chime sounds. (The brake
control is also canceled.) . The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the Intelligent Cruise Control 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 the windshield wiper is oper-
ated at the low speed (LO) or high
speed (HI) position, the Intelligent
Cruise Control system is automati-
cally canceled.
— When strong light (for example, at
sunrise or sunset) is directly shining
on the front of the vehicle
— When rain, snow or dirt adhere to
the system sensor
— On steep downhill roads (the vehi-
cle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
— On repeated uphill and downhill

System operation GUID-21B82D2D-03FC-4413-BEB2-604A50F67D00
WARNINGNormally when controlling the distance to a
vehicle ahead, this system automatically
accelerates or decelerates your vehicle
according to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate 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 its sudden braking or if a
vehicle cuts in. Always stay alert when
using the ICC system.
The driver sets the desired vehicle speed
based on the road conditions. The ICC
system 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: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
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 distance.
The stoplights 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 detection indicator comes
on. The ICC system will also display the set
speed and selected distance.
Vehicle ahead not detected: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
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.
If a vehicle ahead appears during accel-
eration to the set vehicle speed or any time

SSD0611
When passing another vehicle, the set
speed indicator will flash when the vehicle
speed exceeds the set speed. The vehicle
detect indicator will turn off when the area
ahead of the vehicle is open. When the
pedal is released, the vehicle will return 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.
