HOLD function
The HOLD function holds the vehicle at a standstill without requiring you to depress the brake pedal, e.g. while waiting in traffic.
The HOLD function is only an aid. The responsibility for the vehicle safely standing still remains with the driver.
System limits
The HOLD function is only intended to provide assistance when driving and is not a sufficient means of safeguarding the vehicle against rolling away when stationary.
The incline must not be greater than 30%.
