The front air bag is fully deployed if a second

deployment threshold is exceeded within a

few milliseconds.

The deployment of the front-passenger front

air bag is also influenced by the weight

category of the front passenger, which is

determined by the Occupant Classification

System (OCS) (Y page 48).

The lighter the passenger-side occupant, the

higher the vehicle deceleration rate required

(predicted at the start of the impact) for

second-stage inflation of the front-passenger

front air bag. In the second stage, the front

air bags are inflated with the maximum

amount of propellant gas available.

The front air bags are not deployed in

situations where a low impact severity is

predicted. You will then be protected by the

fastened seat belt.

The front-passenger front air bag will only

deploy if:

R

the system, based on the OCS weight

sensor readings, detects that the front-

passenger seat is occupied

R

the PASSENGER AIR BAG OFF indicator

lamp on the center console is not lit

(Y page 48)

R

the air bag control unit predicts a high

impact severity

Driver's knee bag

Driver's knee bag : deploys under the

steering column. It is deployed together with

the front air bags. The driver's knee bag is

designed to operate together with the front

air bags in frontal impacts if certain

thresholds are exceeded. The driver's knee

bag operates best in conjunction with

correctly positioned and fastened seat belts.

The driver's knee bag increases protection of

the driver against:

R

knee injuries

R

thigh injuries

R

lower leg injuries

WARNING

Using unsuitable seat covers could restrict or

even prevent 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

function of the air bag deactivation system

could be restricted. 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.

WARNING

Sensors to control the air bags are located in

the doors. Modifications or work not

performed correctly to the doors or door

paneling, as well as damaged doors, can lead

to the function of the sensors being impaired.

The air bags might therefore not function

properly any more. Consequently, the air bags

cannot protect vehicle occupants as they are

designed to do. There is an increased risk of

injury.

Never modify the doors or parts of the doors.

Always have work on the doors or door

paneling carried out at a qualified specialist

workshop.

You should only use seat covers that have

been approved for your vehicle by Mercedes-

Benz. The seat covers must have a special

tear seam for side impact air bags. Otherwise,

the side impact air bags cannot deploy
