• When driving on the freeway at a set speed and approaching a

slower traveling vehicle ahead, the ICC will adjust 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 will accelerate and maintain 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, the
driver will have to manually control the vehicle speed.

• The sensor sensitivity can be affected by vehicle operation (steering maneuver or driving position in the

lane) or traffic or vehicle condition (for example, if a vehicle is being driven with some damage).

• Normally when controlling the distance to a vehicle ahead, this system automatically accelerates or deceler-

ates own vehicle according to the speed of the vehicle ahead. Depress the accelerator to properly acceler-
ate own 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.

PRECAUTIONS FOR CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE

• In the conventional (fixed speed) cruise control mode, a warning chime does not sound to warn the driver if

own vehicle is too close to the vehicle ahead, as neither the presence of the vehicle ahead nor the vehicle-
to-vehicle distance is detected.

• Pay special attention to the distance between own vehicle and the vehicle ahead or a collision could occur.
• Always confirm the setting in the ICC system display.
• Do not use the conventional (fixed speed) cruise control mode when driving under the following conditions:
- When it is not possible to keep the vehicle at a set speed.
- In heavy traffic or in traffic that varies in speed.
- On winding or hilly roads.
- On slippery roads (rain, snow, ice, etc.).
- In very windy areas.
• Doing so could cause a loss of vehicle control and result in an accident.
• To avoid accidentally engaging cruise control, make sure to the MAIN switch OFF when not using ICC sys-

tem.
