The City Safety function cannot be deactivated. It is activated automatically when the engine/electric operation is started and remains switched on until the engine/electric operation is switched off.
The warning distance determines the sensitivity of the system and regulates the distance at which the visual, acoustic and haptic warnings shall be triggered.
Tap on Settings in top view in the centre display.
Under City Safety, select Later, Normal or Earlier to set the desired warning distance.
Try first with Earlier. If this setting produces too many warnings, which could be perceived as irritating in certain situations, then change to the Normal warning distance.
If warnings are perceived as being too frequent or disturbing then the warning distance can be reduced. This would lead to the system warning at a later stage, which reduces the total number of warnings.
The Later warning distance should only be used in exceptional cases, as in dynamic driving.
City Safety warns the driver when there is a risk of a collision, but it cannot shorten the driver’s reaction time.
For City Safety to be effective, it is recommended always to drive with the warning distance set to Earlier.
Even if the warning distance has been set to Earlier warnings could be perceived as being late in certain situations, e.g. when there are large differences in speed or if vehicles in front brake heavily.
Warning with the direction indicators for Rear Collision Warning deactivates if the warning distance for collision warning is set to the lowest level "Later" (see section "Set warning distance for City Safety").
The seat belt pre-tensioning and braking functions are, however, still active.
No automatic system can guarantee 100 % correct function in all situations. Therefore, never test City Safety by driving at people or vehicles - this may cause severe damage and injury and risk lives.
