Risk of injury caused by performing testing or repair work on airbag or emergency tensioning retractor units. - AS91.00-Z-0001-01A

WARNING: This page is about a different car, the 2011 Mercedes-Benz C300, 2010 Mercedes-Benz C300, 2009 Mercedes-Benz C300, and 2008 Mercedes-Benz C300. However, it is still accessible from the selected car via links, so may be relevant.

Store airbag units with deployment side facing up; do not expose to temperatures greater than 100°C. When working on these units, disconnect the power supply.

Risk of injury

caused by flying objects if an airbag or emergency tensioning retractor unit is triggered accidentally or if an airbag unit is stored with its deployment side face down. When scrapping airbags or emergency tensioning retractor units by means of controlled ignition, a danger is also present if an insufficient safe distance is kept or when opening with cutting torches or other cutting tools, or due to smelting or if parts that have not yet ignited end up in a blaze or a smoldering fire at landfills.

Safety instructions/precautions

Always store removed airbag units with the deployment side facing up.
Acquisition, transportation, storage, testing and assembly work should only be performed or supervised by properly trained personnel.
Install airbag or emergency tensioning retractor units immediately after taking them from the storage room.
Airbag and emergency tensioning retractor units must be protected from flying sparks, open flames and temperatures above 100°C.
Do not transport airbag and emergency tensioning retractor units in the passenger compartment, but rather stow them in the load compartment of the vehicle in their original parts packaging in such a way that they are prevented from sliding around.
Do not let airbag units and emergency tensioning retractors come into contact with grease, oil or cleaning agents.
Perform system tests using approved testing equipment only and only when the units are properly installed and the vehicle is unoccupied.
Before the initial hookup of the battery or an external power supply, the ignition must be switched on and the vehicle unoccupied.
Airbag units and emergency tensioning retractors that have dropped from a height of more than 0.5 m must be replaced.
: The airbag units and emergency tensioning retractors must be disposed of in their original packaging through the MeRSy (Renz) disposal channel in a professional and environmentally suitable manner.
In all countries except national regulations governing proper disposal must be complied with.
A safe distance of at least 10 m must be maintained when scrapping airbag and emergency tensioning retractor units by means of controlled ignition.

Perform the following before performing bodywork, retrofitting work, work on airbag or emergency tensioning retractor units and work on components connected to airbag or emergency tensioning retractor units or that require an intervention into the airbag or emergency tensioning retractor unit electric circuit (e.g. removal of the steering wheel):

Remove ignition key.
Disconnect any external power sources (e.g. battery chargers).
Disconnect and insulate the battery ground cable.
Disconnect plug connection from airbag control unit when working in the interior or when welding.

On vehicles with Keyless Go (KG)

Ensure that no circuit is on.
