Safety and Security Driving safety systems ! Because of the ESP's automatic operation, the engine must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO* start/stop button in position 0 or 1) when the parking brake is being tested on a brake test dynamometer the vehicle is being towed with the front axle raised Active braking action through the ESP may otherwise seriously damage the brake system. The ESP will only function properly if you use wheels of the recommended tire size. For more information, see "Practical hints" ( page 305). Switching off the ESP Warning! Warning! G The ESP cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded. The ESP cannot prevent accidents, including those resulting from excessive speed in turns or hydroplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ESP equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user's safety or the safety of others. G The ESP should not be switched off during normal driving other than in the circumstances described below. Disabling of the system will reduce vehicle stability in standard driving maneuvers. i Distronic* is switched off when ESP is activated. To improve the vehicle's traction, turn off the ESP in driving situations where it would be advantageous to have the drive wheels spin and thus cut into surfaces for better grip such as: starting out on slippery surfaces and in deep snow in conjunction with snow chains sand or gravel The switch is located on the center console. 79
