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 does not describe the selected car, but rather 11 other vehicles, including the 2014 Mercedes-Benz C63 AMG, 2013 Mercedes-Benz C63, 2012 Mercedes-Benz C63, 2011 Mercedes-Benz C63, and 2011 Mercedes-Benz C350. 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 units or seat belt emergency tensioning retractors immediately after taking them from the storage room.
Airbags units and seat belt emergency tensioning retractors must be protected from flying sparks, open flames and temperatures of > 100°C.
Do not transport airbags and emergency tensioning retractors in the passenger compartment, but rather stow them securely in the load compartment of the vehicle in their original replacement part packaging so as to prevent any slippage.
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 acceptable manner.
In all countries except national regulations governing proper disposal must be complied with.
A safe distance of at least 10 meters must be maintained when scrapping airbag units and emergency tensioning retractors with controlled triggering.

The following steps must be taken before starting any bodywork or aftermarket installations, work on airbag units or emergency tensioning retractors, or work on components connected to airbag units or emergency tensioning retractors or work that involves the electric circuits of the airbag units or emergency tensioning retractors (e.g. removal of the steering wheel):

Withdraw ignition key.
Disconnect any external power sources (e.g. battery chargers).
Disconnect control unit connector prior to performing any work in the interior and prior to any welding work.

On vehicles with Keyless Go (KG)

Ensure that no circuit is on.
