75 Safety and Security
Occupant safety
Self-test Occupant Classification
System
After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice, the 56 indicator lamp
located in the center console illuminates. If
an adult occupant is properly sitting on the
front passenger seat and the system
senses the occupant as being an adult,
the56 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 56 indicator lamp will
illuminate and not go out. More information can be found in the
“Practical hints” section (
page 376).
Seat belts
The use of seat belts and infant and child
restraint systems is required by law in all
50 states, the District of Columbia, the
U.S. territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened whenever the vehicle is in
motion.
For more information, see “Fastening the
seat belts” (
page 47).

Only have the seat repaired or replaced
by an authorized Mercedes-Benz
Center.

Read and observe all warnings in this
chapter.
Warning!G
If the 56 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.
iFor information on infants and children trav-
eling with you in the vehicle and restraint sys-
tems for infants and children, see “Children in
the vehicle” (
page 82).

normal driving. Disabling of the system will
result in the following:

no restriction to engine torque

no differential brake support

loss of system supported traction

tracks when the vehicle’s natural oversteer
and understeer characteristics are desired
and requires a highly skilled and
experienced driver able to handle these
critical driving situations.
