Bonnet
Active bonnet (pedestrian protection) Operating principle
i The active bonnet is only available in cer-
tai nc ountries.
The active bonnet can reduce the risk of injury
to pedestrians in certain accident situations.
Raising the active bonnet increases the clear-
anc etoh ard components, such as the engine.
If the active bonnet has been triggered, it is
raised in the area of the bonnet hinges by
abou t100 mm. Th eactive bonnet is trigg ered
by pyrotechnics.
! Once triggered, an active bonnet must be
reset at aqualified specialist workshop,
e.g. aMercedes-Ben zService Centre. The
active bonnet function will then be availa-
ble again. The additional pedestrian pro-
tection provided by the active bonnet will
then be restored.
For the driv etot he workshop, reset the trig-
gere dactive bonnet yourself. After being
reset, the active bonnet rest sinthe area of
the bonnet hinges on the seals, and the bon-
net hinges do not engage. For this reason, we
recommend that you do not exceed amaxi-
mum top spee dof130 km/h on the wa ytothe workshop
.Ifthe active bonnet has been
triggered, pedestrian protection ma ybelimi-
