The system is intended to assist the driver

The system is intended to assist the driver to keep a following distance from the vehicle ahead 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 to help assist the driver to maintain a following distance. The system automatically controls the throttle and applies the brakes (up to 25% of vehicle braking power) if necessary.

The detection range of the sensor is approximately 390 ft (120 m) ahead.

► This system is only an aid to assist the 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.
► This system will not adapt automatically to road conditions. 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 the following objects:
► Stationary and slow moving vehicles
► Pedestrians or objects in the roadway
► Oncoming vehicles in the same lane
► Motorcycles traveling offset in the travel lane

► As there is a performance limit to the WARNING

► As there is a performance limit to the distance control function, never rely solely on the Distance Control Assist 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, depending on the distance to the vehicle ahead and the surrounding circumstances in order to maintain a safe distance between vehicles.
► The system may not function properly under the following conditions. To avoid accidents, never use the Distance Control Assist system under the following conditions: — On roads with sharp curves
— On slippery road surfaces such as on ice or snow, etc.
— On off-road surfaces such as on sand or rock, etc.
— During bad weather (rain, fog, snow, etc.).
— 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 (frequent braking may result in overheating the brakes)
— On repeated uphill and downhill roads
— When towing a trailer or other vehicle

► In some road or traffic conditions, a vehicle 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 DCA system when it is not recommended in this section.
