By activating hill descent, your car can brake in a more controlled and active way. This can be useful if you are driving downhill, as it can help you avoid unwanted acceleration. You can activate hill descent in the display.
 | Hill descent availability is indicated with the hill descent symbol in the driver information area. The symbol turns green when hill descent is active. |
Note
Hill descent is only available at speeds below 40 km/h (25 mph). If you drive faster than this, the function will be deactivated.
