power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle.Warning!
G
Vehicles with Airmatic*: If you have selected
the Comfort suspension tuning
(page 259), the vehicle lowers slightly
when it is locked. You should therefore
make sure that no one is standing near the
wheel arches or lying underneath the vehi-
cle when it is being locked. Otherwise, per-
sonal injury could result.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:
Keep right foot on brake pedal.
Firmly depress parking brake pedal.
Move the gear selector lever to
positionP.
Slowly release brake pedal.
When parked on an incline, turn front
wheel towards the road curb.

86 Safety and SecurityOccupant safetySelf-test Occupant Classification Sys-
tem
After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice, the 75 indicator lamp1
located in the center console illuminates. If
an adult occupant is properly sitting on the
front passenger seat and the system sens-
es the occupant as being an adult, the
75 indicator lamp will illuminate
and go out after approximately 6 seconds.
If the seat is not occupied and the system
senses the front passenger seat as being
empty, the 75 indicator lamp will
illuminate and not go out. For more information, see the “Practical
hints” section (
page 393).Installation of infant and child restraint
systems
This vehicle is equipped with tether an-
chorages for a top tether strap at each of
the rear seating positions.
Not foldable rear seat backrest
1Cover
Remove cover1 from anchorage ring.
Guide tether strap between head re-
straint and top of the seat back.
Warning!
G
If the indicator lamp should not illuminate,
the system is not functioning. You must see
an authorized Mercedes-Benz Center before
seating any child on the front passenger
seat.Warning!
G
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the Occupant Classifi-
cation System. The bottom of the child seat
must make full contact with the passenger
seat cushion. An incorrectly mounted child
seat could cause injuries to the child in case
of an accident, instead of increasing protec-
tion for the child.
Follow the manufacturer’s instructions for
installation of child seats.
