2003 ACCESSORIES/SAFETY EQUIPMENT
Mercedes-Benz - Air Bag Restraint Systems
DESCRIPTION & OPERATION
All models are equipped with Supplemental Restraint System (SRS). The main components of SRS are driver-
side air bag module, passenger-side air bag module, side impact air bag modules (located in doors), SRS control
module, side air bag sensors, SRS warning light, driver-side knee bolster, passenger-side knee bolster and seat
belt pretensioners or Emergency Tensioning Retractor (ETR) seat belt assembly. Additionally, some vehicles
may be equipped with head impact (curtain type) air bags.
Both SRS and ETR are electronically activated by a single control module. There are 2 thresholds which must
be exceeded to trigger an ETR action, air bag deployment, or both. If a moderately severe frontal collision
occurs exceeding first triggering threshold where protection from seat belt is sufficient, only Emergency
Tensioning Retractor (ETR) is activated if seat belt is buckled. If a moderately severe frontal collision occurs
exceeding first triggering threshold where protection from seat belt is sufficient, but seat belt is not buckled, air
bag is deployed and ETR is not activated.
If a severe frontal collision occurs exceeding second triggering threshold where protection from seat belt is
insufficient, air bag is deployed. ETR is activated if seat belt is buckled. If seat belt is not buckled, ETR is not
activated when second triggering threshold is reached. Passenger air bag will deploy even if passenger seat is
not occupied when a triggering threshold is exceeded. During certain types of collisions, the air bags will be
deploy, but ETRs will not be activated.
The side air bag on the driver-side deploys whenever the driver-side air bag module is deployed and when there
is a substantial side impact crash. The air bag on the passenger-side will activate only when a sensor (Occupied
Seat Recognition Sensor) in the passenger seat sends a signal to the SRS control module that the passenger-side
seat is occupied. Side air bags mounted in rear doors will deploy when side impacts occur that exceed preset
parameters.
Head impact air bag modules will deploy when certain side impacts occur that exceed preset parameters. Head
impact air bag will deploy independently of other air bags on side of impact.

SERVICING
SRS AIR BAG label on driver-side door latch post indicates SRS replacement date for air bag units. All SRS
components must be thoroughly inspected, including wiring harness. Before component replacement, check for
SRS fault codes by performing system operation check. See SYSTEM OPERATION CHECK
. SRS service
life is 10 years from manufactured date or 10 years from SRS replacement date after accident related repairs are
completed.
SYSTEM OPERATION CHECK
SRS warning light indicates SRS and Emergency Tensioning Retractor (ETR) system readiness. Turn ignition
on. SRS warning light will illuminate, then turn off after approximately 4-6 seconds indicating SRS system is
functioning properly. If SRS warning light does not illuminate, illuminates while driving or is continuously
illuminated, there is a system fault. Repair malfunctioning system.
AIR BAG SAFETY PRECAUTIONS
Observe these precautions when servicing the air bag system:
When working around SRS components and before any repairs are performed, disable air bag system. See
DISABLING & ACTIVATING AIR BAG SYSTEM
.
Before straightening any damage to body, or before performing electrical arc-welding, disable air bag
system. See DISABLING & ACTIVATING AIR BAG SYSTEM
.
Always wear safety glasses and gloves when handling a deployed air bag module. Air bag module may
contain sodium hydroxide deposits which are irritating to the skin.
Always use control module and impact sensors made by same manufacturer. Using components produced
by different manufacturers could cause accidental air bag or ETR deployment.
DO NOT repair any portion of SRS wiring harness.
If any SRS component is dropped from a height greater than 1.6 feet (0.5 m), it must be replaced.
If SRS components show signs of damage, they must be replaced.
Always handle air bag module with trim cover facing away from your body.
Always place air bag module on workbench with trim cover up, away from loose objects.
