2000-01 ACCESSORIES/SA FETY EQUIPMENT
Mercedes-Benz - Air Bag Restraint Systems
DESCRIPTION & OPERATION
All models are equipped with Supplemental Restraint Syst em (SRS). The main components of SRS are driver-
side air bag module, passenger-side air bag module, si de air bag modules (located in doors), SRS control
module, side air bag sensors, SRS warning light, driver knee bolster, pa ssenger knee bolster, and Emergency
Tensioning Retractor (ETR) seat belt assembly. Additionally, some vehicles may be equipped with head impact
(curtain type) air bags (located ar ound door windows behind door frame trims).
Both SRS and ETR are electronically activated by a single control module. There are 2 thresholds which must
be exceeded to trigger an ETR acti on, air bag deployment, or both. If a moderately severe frontal collision
occurs exceeding first triggering thre shold where protection from safety belt is sufficient, only Emergency
Tensioning Retractor (ETR) is activated if safety belt is buckled. If a moderately severe frontal collision occurs
exceeding first triggering threshold where protection from safety belt is sufficient, but safety 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 safety belt is
insufficient, air bag is deploye d. ETR is activated if safety belt is buckled. If safety 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 thre shold is exceeded. If during a severe frontal collision the power supply is
interrupted, the driver and passenger air bag can still be deployed, but ETR cannot be activated.
The side air bag on the driver-side deploys whenever th e driver-side air bag module is deployed and when there
is a substantial side impact crash. The air bag on the pa ssenger-side will activate only when a sensor (Occupied
Seat Recognition Sensor) in the passenger seat sends a si gnal to the SRS control module that the passenger-side
seat is occupied. During a collision, the side air bag will then deploy.
COMPONENT LOCATIONS NOTE: The following 2000 in
formation represents the latest information available at
time of publication and m ay be useful in diagnosing 2001 vehicles. 2001 wiring
diagrams have been included at the end of this article.
WARNING: Accidental air bag deployment is pos sible. Personal injury may result.
Read and follow all WARNINGS and AIR BAG SAFETY PRECAUTIONS

before working on ai r bag system or related components.

DISABLING SYSTEM
Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Record radio presets and obtain anti-theft
code. Turn ignition switch to OFF position and remove ignition key. If welding on vehicle, disconnect negative
battery cable and disconnect air bag control module.
ACTIVATING SYSTEM
Ensure ignition is off. Reconnect air bag system co mponents (if disconnected). Reconnect negative battery
cable. Perform See SYSTEM OPERATION CHECK
.
DISPOSAL PROCEDURES
Several situations may arise requiring so me form of disposal action, including:
Scrapping a vehicle containing a deployed air bag module and-or ETR.
Scrapping a vehicle with a live air bag module and-or ETR.
Disposal of a live but electrically faulty air bag module and-or ETR.
Disposal of a deployed air bag module and-or ETR.
DEPLOYED AIR BAG OR ETR
Deployed air bag module and-or ETR unit can be thrown away. None of its components are reusable. Deployed
air bag module is NOT classified as hazardous material.
SCRAPPED VEHICLE
1. Before proceeding, follow service precautions. See AIR BAG SAFETY PRECAUTIONS . Move
vehicle outdoors to a remote area, away from work shop and other personnel. Disconnect and shield
negative battery cable. Open al l vehicle windows and doors.
2. Ensure air bag module is secured to steering wheel, and passenger air bag is secured to dash. Ensure ETR
seat belt assemblies are secured to "B" pillars and all seat belt buckles are latched. Remove loose ob
jects
CAUTION: On CL500, open doors before
disconnecting battery. Opening doors
allows windows to automa tically lower thus preventing roof seal damage.
WARNING: An undeployed air bag module or ET R should never be disposed of
without first being deplo yed. See SCRAPPED VEHICLE
. If deployment is
not possible, contact vehicle manuf acturer for further instructions.
WARNING: An undeployed air bag m odule and-or ETR seat belt CANNOT be disposed
of without first being de ployed. If this is not possible through procedures
outlined below, contact vehicle ma nufacturer for further instructions.
Perform remote deployment outdoors . Keep personnel at least 20 feet
away.

CONTROL MODULE PROGRAMMING
After control module replacement, SRS warning light will blink or illuminate continuously. This indicates need
to program and set paramete rs of SRS control module. This process requires use of Hand-Held Tester (965 589
00 01). During programming, the follow ing conditions need to be met:
Vehicles Without Side Air Bag
Version with passenger-side air bag module, when replac ing SRS control module is to be set to YES when
programming control module. Version with seat belt buckle switch is to be programmed NO.
Vehicles With Side Air Bag
Version is set to YES when replacing SRS control module. Version with seat belt buckle switch is set to YES.
Seat occupation recogni tion is set to YES.
Parameters
After programming, SRS warning light wi ll continue to blink, indicating need to set parameters. Currently,
parameters set is identical for all models.
