Occupant safety
Occupant Classification System
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a
nearly upright position with their back
against the seat backrest and feet on the
floor to be correctly classified. If the occu-
pant’s weight is transferred to another
object in the vehicle (e.g. by leaning on
armrests), the OCS may not be able to
properly approximate the occupant’s
weight category.Both driver and the front passenger should
always use the 56indicator lamp
as an indication of whether or not the front
passenger is properly positioned.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 18.6 kg (41 lbs) until they
reach a height where a lap/shoulder belt fits
properly without a booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised
children in a child restraint system may use
vehicle equipment and may cause an acci-
dent and/or serious personal injury.
iThe system does not deactivate the
front passenger side impact air bag,
the window curtain air bag and the
emergency tensioning device.
iIf your seat, including your trim cover
and cushion needs to be serviced in
any way, take the vehicle to your
authorized Mercedes-Benz Center.
Only seat accessories approved by
Mercedes-Benz may be used. Warning!
G
If the 56indicator lamp illuminates
when an adult or someone larger than a
small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
56indicator lamp goes out.

ming is available for a monthly subscrip-
tion fee.
