Safety and Security Driving safety systems To maintain the proper distance to the vehicle in front of you and thus prevent a rear-end collision, you must apply the brakes yourself. Immediately brake the vehicle to avoid a collision. Under no circumstances should the driver await the intermittent warning sound before braking. See the following warning note. The intermittent warning sound ceases and the distance warning lamp l goes out when the necessary distance to the vehicle ahead is again established. Warning! G Warning! G PRE-SAFE® Brake brakes your vehicle with a maximum of 13 ft/s2 (4 m/s2). This corresponds to about 40% of the maximum deceleration ability of your vehicle. This automatic braking is intended only to initiate the braking if the driver has not already done so. The driver must apply the brakes in order to prevent a collision. PRE-SAFE® Brake applies the brake pedal automatically which results in the brake pedal moving. Therefore keep driver's foot area clear at all times, including the area under the brake pedal. Objects stored in this area may impair pedal movement which could interfere with the braking ability of the PRE-SAFE® Brake. Do not place your foot under the brake pedal - your foot could become caught. An intermittent warning sounds and the distance warning lamp l in the instrument cluster is illuminated if PRE-SAFE® Brake calculates that the distance to the vehicle ahead and your vehicle's current speed indicate that PRE-SAFE® Brake will not be capable of slowing the vehicle sufficiently to maintain the preset following distance, which creates a danger of a collision. Immediately brake your vehicle to increase the distance between your vehicle and the vehicle driving in front of you. The warning sound is intended as a final caution that you have not interceded with your own braking inputs to avoid a potentially dangerous situation. Do not wait for the operation of the warning signal to intercede with your own braking, as that will result in potentially dangerous emergency braking which will not always result in an impact being avoided. Tailgating increases the risk of an accident. 77
