Starting assistant
The starting assistant enables you to start off
conveniently on slopes. The handbrake is not
required for this purpose.

2. Release the footbrake and drive off quickly.
The starting assistant holds the vehicle
for approx. 2 seconds after releasing the
footbrake. After releasing the footbrake, drive
off quickly, otherwise the starting assistant no
longer holds the vehicle after approx. 2 seconds
and it begins to roll back.
