Safety and Security Driving and safety systems ! Because of the ESP's automatic operation, the engine must be shut off (SmartKey in starter switch position 0 or 1) when the parking brake is being tested on a brake test dynamometer. Active braking action through ESP may otherwise seriously damage the front or rear axle brake system. Operational tests with the engine running can only be conducted on a two-axle dynamometer. LOW RANGE - ESP During off-road driving, a special low range system for the ESP is operational with transmission in LOW RANGE mode ( page 125). In the LOW RANGE mode, the ESP operates in a traction improving fashion specifically adapted for off-road driving. At speeds below 27 mph (45 km/h), the ESP assists in over-/understeering, thus improving vehicle traction. 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, following another vehicle too closely, 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. 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 in sand or gravel when driving off-road 81
