Special service requ irements
The prescribed service inter val is based on nor‐
mal operation of theve hicle. Service workwill need
tobe per form ed more of ten if theve hicle
is operated under arduous conditions or
increased loads, forex ample:
Rregular city driving with frequent intermedi‐
ate stops.
Rif th eve hicle is primarily used totrave l short
dis tances.
Rfor frequent operation in mountainous terrain
or on poor road sur faces.
Rif th e engine is of ten le ftidling for long peri‐
ods.
Rin particula rly dusty condition sand/o rif air -
re circulation mode is frequently used.
In these or similar operating conditions, ha vethe
interior air filter, engine air filter, engine oil, oil
fi lter etc. changed more frequent ly.Th etire s
must be checked more frequently if theve hicle
is operated under increased loads. Further infor‐

Engine compartment
Ac tive hood (pedestrian pr otection)
Operation of the active hood (pedestrian pro‐
te ction)
In cer tain accident situations, therisk of injury
to pedestrians can be reduced bythe actuation
of the active hood. The rear area of the engine
hood is raised byappr oximately 85 mm.
Fo rth e drive tothewo rkshop, reset the trig‐
ge red active hood yourself. Ifth e active hood
has been triggered, pedestrian pr otection may
be limited.
A qu alified specialist workshop must re-ins tate
th e full functionality of the active hood. The active hood is not
available in all countries.

WARNING Risk of burn s from hot com‐
ponent parts in the engine compartment
Cer tain component parts in the engine com‐
partment can be very hot, e.g. the engine,
th e cooler and parts of theex haust sy stem.
#Let the engine cool down and only
to uch the component parts described
as follo ws .
#With your hand flat, push down active hood
1 inthe area around the hinges on bo th
sides (ar rows).
The engine hood must engage in position.
#If th e active hood can be raised slightly at
th ere ar passenger compartment in the area
of the hinges, repeat thestep until it engages
cor rectly in position.
Opening/closing the hood
&
WARNING Risk of accident if the engine
hood is unlatched while driving
An unloc ked engine hood may open up when
th eve hicle is in motion and block your vie w.
#Never unlatch the engine hood while
driving.
#Before every trip, ensure that the
engine hood is latched.

WARNING Risk of an accident due to
insuf ficient tire pressure
Ti re s with pressure that is too low can over‐

In addition, they also suf fer from excessive
and/or ir regular wear, which can significantly
impair the braking properties and the han‐
