CAUTION

■

Before using dynamic radar cruise control

Do not overly rely on vehicle-to-vehicle distance control.

Be aware of the set vehicle speed. If automatic deceleration/acceleration is not

appropriate, adjust the vehicle speed, as well as the distance between your vehicle

and vehicles ahead by applying the brakes, etc.

■

To avoid operating the dynamic radar cruise control by mistake

Keep the “ON-OFF” button off when not in use.

fatal accident.
