Notes on changing bulbs

Bulbs and lamps are an important aspect of vehicle safety. You must therefore make sure that all bulbs function correctly at all times.

Risk of injury

Bulbs and lamps can be very hot. You should therefore allow them to cool down before you change them. Otherwise, you could be burned if you touch them.

Keep bulbs out of the reach of children. Otherwise, they could damage them, for example, and injure themselves.

Never use a bulb which has been dropped. Such a bulb may explode and injure you.

H7 bulbs are pressurised and could explode when you change them, particularly if they are very hot. You should therefore wear eye protection and gloves when you are changing them.

Risk of injury

Xenon bulbs are under high voltage. You could get an electric shock and be seriously or even fatally injured if you touch the electric contacts on xenon bulbs. Do not, therefore, remove the cover on xenon bulbs.

Do not change xenon bulbs yourself, but have them replaced at a qualified specialist workshop which has 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. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop.

Risk of injury

HiP bulbs are pressurised and may explode when you change them, thereby injuring you.

Do not change HiP bulbs yourself; have them replaced at a qualified specialist workshop which has 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. In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop.


Do not change the LEDs yourself. You could otherwise damage the LEDs or parts of the vehicle.
