Safety and security Driving safety systems 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. 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. X Brake the vehicle immediately to avoid a collision. Under no circumstances should the driver await the intermittent warning sound before braking. Observe 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. 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. PRE-SAFE® Brake can react to stationary obstacles such as standing or parked vehicles at road speeds of up to approximately 40 mph (70 km/h). Apply the brakes yourself to avoid a collision. Activating and deactivating: Activate or deactivate PRE-SAFE® Brake using the instrument cluster control system (Y page 244). After the function has been activated, indicator : appears on the left-hand side of the multifunction display. PRE-SAFE® Brake does not always clearly interpret complex traffic situations. If a visual and/or acoustic warning is issued in an uncritical driving situation, or if the vehicle brakes lightly, you can interrupt the PRESAFE® Brake maneuver by pressing down all the way on the accelerator pedal, using kickdown, or releasing the brake pedal. The PRE-SAFE® Brake maneuver is terminated immediately when Ryou Ryou Ran X G Warning!
