WARNING
For safety reasons, always drive with the rear
head restraints in the upright position when
the rear seats are occupied.
Keep the
area around head restraints clear of
articles (e.g. clothing) to not obstruct the
folding operation of the head restraints. G
WARNING
For your protection, drive only with properly
positioned head restraints.
Adjust the

head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for injury to the head and neck in the event of an
accident or similar situation.
Do
not

drive the vehicle without the seat head
restraints. Head restraints are intended to
help reduce injuries during an accident.

i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are

Important safety notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on

even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations. In these countries, the daytime
running lamps are automatically switched on
when the engine is started. Information about driving abroad
To convert to symmetrical low beam
when driving

abroad: switch the headlamps
to symmetrical low beam in countries in
which traffic drives on the opposite side of the
road from the country where the vehicle is
registered. This prevents glare to oncoming
traffic. Symmetrical lights do not illuminate
as large an area of the edge of the road.
Have the headlamps converted at a qualified
specialist workshop as close to the border as
possible before driving in these countries.
To convert to asymmetrical low beam
after returning: have the headlamps
converted back to asymmetrical low beam at
a qualified specialist workshop as soon as
possible after crossing the border and
returning to the original country. Light switch
