Side impact air bags
G
WARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they are
designed to do. In addition, the operation of
the occupant classification system (OCS)
could be adversely affected. This poses an
increased risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Front side impact air bags : and second row
rear side impact air bags ; deploy next to the
outer bolster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax protection. It also offers addi-
tional pelvis protection for occupants in the
front seats. However, it does not protect the:
R
head
R
neck
R
arms
If the restraint system control unit detects a side
impact, the side impact air bag is deployed on
the side on which the impact occurs.
The side impact air bag on the front passenger
side deploys under the following conditions:
R
the OCS system detects that the front
passenger seat is occupied or
R
the seat belt buckle tongue is engaged in the
belt buckle of the front passenger seat
If the belt tongue is engaged in the belt buckle,
the side impact air bag on the front passenger
side deploys if an appropriate accident situation
occurs. In this case, deployment is independent
of whether the front passenger seat is occupied
or not.
Window curtain air bags
Window curtain air bags : are integrated into
the side of the roof frame and deploy in the area
extending from the front door (A-pillar) to the
rear side window (D-pillar).
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or arms.
If the restraint system control unit detects a side
impact, the window curtain air bag is deployed
on the side on which the impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations
(Y page 56).
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-
egorizes the person in the front-passenger seat.
Depending on that result, the front-passenger
front air bag is either enabled or deactivated.
The system does not deactivate:
R
the side impact air bag
R
the window curtain air bag
R
the Emergency Tensioning Devices
