Safety and Security
Occupant safety
When you sell your vehicle, we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.
Front air bags
1 Driver air bag
2 Passenger air bag
3 Knee bag
Driver and passenger air bags and driver’s
side knee bag are deployed:
앫 in the event of certain frontal impacts
앫 if impact exceeds a preset deployment
threshold
앫 independently of the head-thorax air
bags
The air bags will not deploy in impacts
which do not exceed the system’s
deployment thresholds. You will then be
protected by the fastened seat belts.
앫 In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
앫 For your protection and the protection
of others, when scrapping the air bag
unit or emergency tensioning device,
our safety instructions must be
followed. These instructions are
available from any authorized
Mercedes-Benz Center.
앫 Given the considerable deployment
speed, required inflation volume, and
the textile structure of the air bags,
there is the possibility of abrasions or
other, potentially more serious injuries
resulting from air bag deployment.
i
The front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of relevant vehicle decelera-
tion as assessed by the air bag control unit.
On the passenger side, the front air bag deploy-
ment is additionally influenced by the passen-
ger’s weight category as identified by the
Occupant Classification System (OCS)
(
컄 page 74).
The lighter the passenger side occupant, the
higher the vehicle deceleration rate required for
the second stage inflation of the air bag.
