You could lose control of the vehicle in the following situations in particular:

when braking
in the event of abrupt steering manoeuvres and/or when the vehicle's speed is not adapted to the road conditions

In the event of a short circuit or a similar incident, contact a qualified specialist workshop immediately.

Mercedes-Benz recommends that you have the starter battery replaced at a qualified specialist workshop, e.g. a Mercedes-Benz Service Centre.

If you want to replace the battery yourself, observe the following information:

Only replace a faulty battery with a battery which fulfils the vehicle's specific requirements.
Carry over detachable parts such as the vent hose or terminal cover from the battery which is to be replaced.
Make sure that the vent hose is always connected to its original opening on the battery side.
Fit the existing or newly supplied stop plugs.
Otherwise, gases or battery acid could escape.
Make sure that the detachable parts are connected in the same way as before.

For safety reasons, Mercedes-Benz recommends that you only use batteries that have been tested and approved for your vehicle by Mercedes-Benz . These batteries provide increased impact protection to prevent vehicle occupants from suffering acid burns should the battery be damaged in an accident.

WARNING Risk of explosion due to electrostatic charge

Electrostatic charge can ignite the highly explosive gas mixture in the battery.

To discharge any electrostatic charge that may have built up, touch the metal vehicle body before handling the battery.

The highly flammable gas mixture is created while the battery is charging and when jump-starting.

WARNING Danger of chemical burns from the battery acid

Battery acid is caustic.

Avoid contact with the skin, eyes or clothing.

Do not lean over the battery.

Do not inhale battery gases.

Keep children away from the battery.

Immediately rinse battery acid off thoroughly with plenty of clean water and seek medical attention immediately.
