G Cruise control is a convenience system designed to assist the driver during vehicle operation. The driver is and must always remain responsible for the vehicle speed and for safe brake operation. Only use cruise control if the road, traffic and weather conditions make it advisable to travel at a steady speed. The use of cruise control can be dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a steady speed. The use of cruise control can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control. Deactivate cruise control when driving in fog. The "Resume" function should only be operated if the driver is fully aware of the previously set speed and wishes to resume this particular preset speed. 231
