WARNING: This page is about a different variant/trim than selected.
- The following hazards are present when the battery is connected:
- Damage to control units during welding work on the body.
- Accidental triggering of airbags during straightening work on the body.
Due to these potential hazards, it is essential to disconnect the battery negative lead prior to welding and straightening work. Prior to disconnecting the negative lead, interrogate the fault memories of the control units if necessary. Refer to 12 00... INSTRUCTIONS FOR DISCONNECTING AND CONNECTING BATTERY (N52K), 12 00... INSTRUCTIONS FOR DISCONNECTING AND CONNECTING BATTERY (N51) and 12 00... INSTRUCTIONS FOR DISCONNECTING AND CONNECTING BATTERY .
- Control units are designed for a temperature of 65°C. The temperatures in a spraying booth do not pose any problems. If a vehicle is inside the spraying booth at an indicated temperature of 80°C, the actual temperature of the vehicle will be ≤ 60°C (object temperature).
- Protects control units against the effects of heat at temperatures > 65°C (e.g. during welding and drying with an infrared radiator or hot air blower).
