Hold function
Concept
The system holds the vehicle automatically when
gear is engaged. This prevents rolling against the
direction of travel.
In selector lever position D, the vehicle cannot
roll backwards. In selector lever position R, it can‐
not roll forward. The brake pedal does not have
to be pressed.
Reducing energy consumption
To reduce energy consumption when the hold
function is activated, activate the parking brake
or engage the selector lever in position P when
the vehicle is stopped for long periods of time.
The hold function can be affected by the vehi‐
cle's load and the road incline. If needed, a
Check Control message will appear and position
P will be selected automatically.
