Observe the "Important safety notes" section.

WARNING
ESP® should not be deactivated during normal driving other than in the circumstances described below. Disabling the system will reduce vehicle stability in driving maneuvers.
Do not deactivate ESP® when the emergency or spare wheel is mounted.

ESP® is activated automatically when the engine is started.

It may be best to deactivate ESP® in the following situations:
- when using snow chains
- in deep snow
- on sand or gravel

WARNING
Switch on ESP® immediately if one of the previously stated conditions is no longer met.
Otherwise, ESP® cannot stabilize the vehicle if it begins to lurch or when a wheel spins.

When you deactivate ESP®:
- ESP® no longer improves driving stability.
- the engine's torque is no longer limited and the drive wheels can spin. The spinning of the wheels results in a cutting action, which provides better grip.
- traction control is still activated.
- ESP® still provides support when you brake.

If ESP® is deactivated and one or more wheels start to spin, the ESP® warning lamp in the instrument cluster flashes. In such situations, ESP® will not stabilize the vehicle.

- To deactivate: press button 1.
The ESP® OFF warning lamp in the instrument cluster lights up.

WARNING
When the ESP® OFF warning lamp is lit, ESP® is deactivated.
If the ESP® warning lamp and the ESP® OFF warning lamp remain lit, ESP® is not available due to a malfunction.
When ESP® is deactivated or not operational, vehicle stability in standard driving maneuvers is reduced.
Adapt your speed and driving to the prevailing road conditions and to the non-operating status of the ESP®.

Avoid spinning the driven wheels for an extended period with ESP® deactivated.
You could otherwise damage the drivetrain.

- To activate: press button 1.
The ESP® OFF warning lamp in the instrument cluster goes out.
