Work carried out incorrectly on the battery can, for example, lead to a short circuit. This can lead to function restrictions in safety-relevant systems, e.g. the lighting system, ABS (anti-lock braking system) or ESP® (Electronic Stability Program). The operating safety of your vehicle may be restricted.
when braking
in the event of abrupt steering manoeuvres and/or when the vehicle's speed is not adapted to the road conditions
Mercedes-Benz recommends that you have the 12 V battery replaced at a qualified specialist workshop, e.g. at a Mercedes-Benz Service Centre.
Always replace a faulty battery with a battery which fulfils the vehicle's specific requirements.
Carry over detachable parts such as the vent hose, elbow fitting or terminal cover from the battery 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.
Electrostatic charge can cause sparks which may ignite the highly flammable gas mixture in the battery.
The highly flammable gas mixture is created while the battery is charging and when jump-starting.
Battery acid is caustic.
Batteries contain pollutants. It is illegal to dispose of them with the household rubbish.
If the 12 V battery has to be connected, contact a qualified specialist workshop.
