Switching off the traction control system (ASR)

In particular circumstances, it may be advisable to switch off the traction control system (ASR) to allow a certain amount of wheel slip. For example:

• • Rocking the car backwards and forwards to free it
• • Driving in deep snow or on loose surfaces
• • Driving with snow chains

Press the button briefly ⇒ fig. 232 or ⇒ fig. 233. The warning lamp will light up and the message ASR off will appear in the driver information system display.

The traction control system (ASR) can only be switched off at speeds below 50 km/h on vehicles with front-wheel drive. At 70 km/h it will switch on again automatically. The ASR can be deactivated at any speed on vehicles with four-wheel drive.

Switching off the ESP

Press the button for longer than 3 seconds. The ESP warning lamp will light up and the message ESP switched off will appear in the display. The ASR is also deactivated when the ESP is switched off.

Switching on

Press the button again. The message ESP/ASR on will appear briefly on the display.

WARNING

You should switch off the ESP only if your driving ability and traffic conditions allow you to do so safely. Please note that, when the ASR and ESP are switched off, the driven wheels may start to spin, causing the vehicle to lose grip, in particular on slippery or wet roads - danger of skidding!

Note

The ASR and ESP cannot be switched off when the adaptive cruise control (ACC)* is on.
