driver's door is opened, the electric parking brake
is activated automatically.

WARNING
Loss of Control over
the Vehicle
The limits set by the physics of driving cannot be
overcome, even with the drive-off assistant. Despite
the drive-off assistant, responsibility for stopping
and starting on gradients lies with the driver.
When stopping and starting on slippery surfaces
(e.g., icy or loose substrate) the drive-off assistant
cannot be guaranteed to provide assistance. The
vehicle can slip in such cases.
e
Always adjust your driving style to the road
surface and the vehicle load; use the footbrake if
necessary.
If the drive-off assistant is not working, it is no longer
possible to assist the driver when driving off on
gradients.
e
Hold the vehicle with the footbrake.
