In exceptional conditions (starting a vehicle which is bogged down, stuck in snow, on soft ground...), it may be advisable to deactivate the ASR and ESP systems, so that the wheels can move freely and regain grip.

Press the "ESP OFF" button, located on the left below the steering wheel.

If this warning lamp comes on in the instrument panel and the indicator lamp on the button comes on, this indicates that the ASR and ESP systems are deactivated.
