Engine compartment

Active hood (pedestrian protection)
Operation of the active hood (pedestrian pro‐
tection)
In certain accident situations, the risk of injury
to pedestrians can be reduced by the actuation
of the active hood. The rear area of the engine
hood is raised by approximately 85 mm.
For the drive to the workshop, reset the trig‐
gered active hood yourself. If the active hood
has been triggered, pedestrian protection may
be limited.
A qualified specialist workshop must re-instate
the full functionality of the active hood.
The active hood is not available in all countries.
Resetting the active hood
& WARNING Risk of burns from hot com‐
ponent parts in the engine compartment
Certain component parts in the engine com‐
partment can be very hot, e.g. the engine,
the cooler and parts of the exhaust system.
Let the engine cool down and only
#
touch the component parts described
as follows.
With your hand flat, push down active hood
#
1 in the area around the hinges on both
sides (arrows).
The engine hood must engage in position.
If the active hood can be raised slightly at
#
the rear passenger compartment in the area
of the hinges, repeat the step until it engages
correctly in position.
Opening/closing the hood
& WARNING Risk of accident if the engine
hood is unlatched while driving
An unlocked engine hood may open up when
the vehicle is in motion and block your view.
Never unlatch the engine hood while
#
driving.
Before every trip, ensure that the
#
engine hood is latched.
