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

the followin ginstructions in order to avoid
damage to the paintwork due to incorrect
care.
These notes also appl ytolight alloy wheels
with aclear mat tfinish.
! Neve rpolish the vehicle or the light alloy
wheels. Polishing makes the paintwork
shiny. !
The following ma ycause the paint to
become shiny and thus reduce the matt
effect:
R Vigorous rubbing with unsuitable mate-
rials.

R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or pol-
ishing products, or glos spreserver, e.g.
wax .These product sare onl ysuitable for
high-glos ssurfaces. Thei ruse on vehicles
wit hm att finish leads to considerable sur-
face damage (shiny, spotted areas).
