Window curtain air bags : are deployed:

on the side on which an impact occurs

at the start of an accident with a high rate of

lateral vehicle deceleration or acceleration,

e.g. in a side impact

regardless of whether the front-passenger

seat is occupied

independently of the use of the seat belt

independently of the front air bags

Window curtain air bags : will not deploy in

the event of impacts which do not exceed the

system's preset deployment thresholds for

vehicle acceleration/deceleration. You will

then be protected by the fastened seat belt.

Occupant Classification System

(OCS)

How the Occupant Classification Sys-

tem works

The Occupant Classification System (OCS)

categorizes the occupant on the front-

passenger seat using a weight sensor. The

front-passenger front air bag is deactivated

automatically for certain weight categories.

The PASSENGER AIR BAG OFF indicator lamp

shows you the current status. If the

PASSENGER AIR BAG OFF indicator lamp is

lit, the passenger air bag is disabled.
The system does not deactivate:

the side impact air bag

the pelvis air bag

the window curtain air bag

the Emergency Tensioning Devices

To be classified correctly, the front passenger

must sit:

with the seat belt fastened correctly

in a position that is as upright as possible

with their back against the seat backrest

with their feet on the floor

The OCS weight sensor reading is affected if

the occupant's weight is transferred, e.g. by

leaning on the armrest.
If the front-passenger seat, the seat cover or

the seat cushion are damaged, have the nec-

essary repair work carried out at a qualified

specialist workshop.
For safety reasons, Mercedes-Benz recom-

mends that you only use seat accessories

that have been approved by Mercedes-Benz.
Both the driver and the front passenger

should always observe the PASSENGER AIR

BAG OFF indicator lamp as an indication of

whether or not the front passenger is posi-

tioned correctly. Observe also the air bag dis-

play messages that can be displayed in the

instrument cluster (

page 215).

WARNING

If the 45 indicator lamp illuminates

when an adult or someone larger than a small

individual is in the front passenger seat, have

the front passenger reposition himself or her-

self in the seat until the 45 indicator

lamp goes out.
In the event of a collision, the air bag control

unit will not allow front passenger front air bag

deployment when the OCS has classified the

front passenger seat occupant as weighing as

much as or less than a typical 12-month-old

child in a standard child restraint or if the front

passenger seat is classified as being empty.
When the OCS senses that the front

passenger seat occupant is classified as

being up to or less than the weight of a typical

12-month-old child in a standard child

restraint, the 45 indicator lamp will

illuminate when the engine is started and
