System
After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice (
page 372), the 59
indicator lamp1 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, the 59 indi-
cator 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 59indicator lamp
will illuminate and not go out.For more information, see the “Practical
hints” section (
page 640).
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 fas-
tened whenever the vehicle is in motion.
Warning!
G
If the 59 indicator lamp should
not illuminate, the system is not functioning.
You must contact an authorized
Mercedes-Benz Center before seating any
child on the front passenger seat.Warning!
G
Never place anything between seat cushion
(e.g. pillow), since it reduces the effective-
ness of the Occupant Classification 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 protection for the
child.
Follow the manufacturer’s instructions for
installation of child seats.

Bring the rear power seat backrest* to
its fully upright position (
page 375).
Fold upholstery cover3 upward.
Turn installation device4 to a vertical
position so that upholstery cover3
does not fold down.
Install child seat according to the man-
ufacturer’s instructions.
A rigid connection is established be-
tween the child seat and the body of
the vehicle.Override switch for rear passenger
compartment
You can disable select functions in the rear
passenger compartment for added safety
(for instance when you have children riding
in the rear passenger compartment).
You can disable the following functions in
the rear passenger compartment:
rear door window operation
(page 410)
adjustment of front passenger seat
from the rear* (
page 376)
rear center console lighter
(page 537)
sunblinds for panorama roof*
(page 521)
rear window sunshade (
page 535)
and rear side window sunshades
(
page 412)
Warning!
G
Vehicles with rear power seats*: Never ad-
just the rear seat position after installing the
child restraint. Adjusting the rear seat posi-
tion after installing the child restraint could
damage the child restraint and/or introduce
undesirable slack or tension into the seat
belt and loosen or misposition the child re-
straint, lessening the effectiveness of the
child restraint and thus increasing the
chance or severity of injury in an accident.i

Make sure the seat belt for the center seat can
operate freely with a child seat installed.
