WARNING: This page is about a different car, the 2011 BMW 750xi, 2011 BMW 750Lxi, 2010 BMW 750xi, and 2010 BMW 750Lxi. However, it is still accessible from the selected car via links, so may be relevant.
- The following risks exist when the battery is connected:
- Damage to control units resulting from welding work on the body or a line short circuit.
- Accidental activation of airbags during straightening work on the body.
Because of these risks the battery negative lead must be disconnected prior to all repair work.
- Control units are designed for a temperature of 65 °C. The temperatures in a spray booth do not pose any problems. If a vehicle is in the spray booth at a displayed temperature of 80°C, the actual temperature of the vehicle is ≤ 60 °C (object temperature).
- Protect control units against effects of heat >65 °C (e.g. during welding and drying work with an infrared radiator or hot air blower).
