For information on the ABS, Adaptive Brake, BAS, BAS Plus*, EBP, ESP® and PRE-SAFE® Brake*, see "Driving safety systems" ( page 66). Cruise control Warning! The cruise control automatically maintains the speed you set for your vehicle. The use of the cruise control is recommended for driving at a constant speed for extended periods of time. You can set or resume the cruise control at any speed over 20 mph (30 km/h). The cruise control function is operated by means of the cruise control lever. G The 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's speed and for safe brake operation. Only use the cruise control if the road, traffic, and weather conditions make it advisable to travel at a steady speed. The use of the 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 the cruise control can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control. Deactivate the 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. 419
