WARNING
The intelligent technology in the hold assist* and hill hold assist functions cannot defy the laws of physics. Do not let the extra convenience afforded by the hold assist* and hill hold assist functions tempt you into taking any risks when driving – this can cause accidents.
- The hold assist* and hill hold assist functions cannot keep the vehicle stationary in all conditions on a gradient (e.g. if the road is slippery or icy).
- Always ensure that the vehicle is stopped properly and safely – risk of accident!
CAUTION
Switch off the hold assist* function before driving the vehicle into a car wash.
