Important safety instructions

Xenon lamps

If your car is equipped with xenon lamps, then when the engine is started, the light cone of the xenon lamps moves from top to bottom and back. In this case, the light must be turned on before starting the engine.

Xenon lamps are under high voltage. If you touch the electrical contacts of xenon lamps, you can get an electric shock, which can cause serious or even fatal injuries. Therefore, do not remove the covers of xenon lamps.

Do not replace xenon lamps yourself; always contact a specialized workshop that has the appropriate specialists and tools to carry out the required work.

Mercedes-Benz recommends using the services of a Mercedes-Benz service centre for this purpose. In particular, in the case of work related to safety or work on systems that ensure safety, it is essential to contact a specialist workshop with qualified personnel.
