■
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.

Doing so may result in inappropriate control of speed and could cause serious or
fatal accident.

●
On roads with sharp bends
●
On winding roads
●
On slippery roads, such as those covered with rain, ice or snow
