All work on the vehicle and, in particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. The specialist workshop must have the necessary specialist knowledge and tools to carry out the work required. Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.

Some safety systems only function when the engine is running. You should therefore never switch off the engine when driving. Otherwise the safety systems of your vehicle may no longer protect you and other persons as intended. In addition, there is the danger that you may lose control of your vehicle and thus cause an accident.

Work carried out incorrectly, or alterations made to the vehicle, e.g. rerouting of cables under coverings, could cause the safety systems of your vehicle to stop working properly. The safety systems would thus no longer protect you and other persons as intended. In addition, there is the danger that you may lose control of your vehicle and thus cause an accident.

All work and alterations to the vehicle, e.g. installations or modifications, should therefore be carried out at a qualified specialist workshop.

A heavy impact to the underbody, tyres or wheels, for example when bottoming out on rough terrain or driving over an obstacle at high speed, could damage your vehicle. As a result, you could cause an accident. This also applies to vehicles which are equipped with underbody protection.

For this reason, drive slowly over obstacles, avoid bottoming out the vehicle in rough terrain and, if necessary, have your vehicle checked at a qualified specialist workshop.

If work on electronic equipment and its software is carried out incorrectly, this equipment could stop working. The electronic systems are networked via interfaces. Tampering with these electronic systems could cause malfunctions in systems which have not been modified. Malfunctions such as these can seriously jeopardise the vehicle's operating safety and therefore your own safety.

You should thus have all work and modifications to electronic components carried out at a qualified specialist workshop.
