Active pedestrian protection
Principle
With the active pedestrian protection system,
the bonnet is raised if the vehicle's front end
collides with a pedestrian. Sensors underneath
the bumper are used for detection. This pro‐
vides additional deformation space underneath
the bonnet for the subsequent head impact.
Safety notes
WARNING
The system can trigger inadvertently if
contact is made with individual components of
the hinges and bonnet locks. There is a danger
of injury or damage to property. Do not touch
individual components of the hinges and bon‐
net locks.◀
WARNING
Changes to the pedestrian protection
system can lead to a failure, a malfunction or
accidental triggering of the pedestrian protec‐
tion system. There is a danger of injury or even
death. Do not modify individual components of
the pedestrian protection system or its wiring
in any way. Do not dismantle the system.◀
WARNING
Work carried out incorrectly can lead to a
failure, a malfunction or accidental triggering of
the system. If there is a malfunction, the sys‐
tem might not trigger as intended in an acci‐
dent, in spite of the accident being of the ap‐
propriate severity. There is a danger of injury
or even death. Have the system tested, re‐

tection. There is a danger of damage to prop‐
erty. Do not open the bonnet after the Check
