269 Battery
Technical

and controlsOperation DrivingInstrument 
cluster displayPractical hintsCar care Index Therefore, we strongly recommend that you have the 
battery charge checked frequently, and corrected if 
necessary, especially if you use the vehicle less than 
approximately 200 miles (300 km) per month, 
mostly for short distance trips, or if it is not used for 
long periods of time.
Only charge a battery with a battery charger after the 
battery has been disconnected from the vehicle’s 
electrical circuit.
Always disconnect the battery negative lead first and 
connect last.
When removing and connecting the battery, always 
make sure that all electrical consumers are off and the 
electronic key is in steering lock position 0. The battery 
and its filler caps must always be securely installed 
when the vehicle is in operation. During removal and 
installation always protect the disconnected battery 
positive (+) terminal with the cover attached to the 
battery.
While the engine is running the battery terminal clamps 
must not be loosened or detached, otherwise the 
generator and other electronic components would be 
damaged.Note:
After reconnecting the battery also set the clock (see 
page 108), resynchronize the front seats (see page 49), 
front seat head restraints (see page 49), the express 
feature of the power windows (see page 148), the 
sliding/pop-up roof (see page 150) and the electronic 
stability program (ESP) (see page 219).
Battery recycling
Batteries contain material that can harm the 
environment with improper disposal.
Large 12 Volt storage batteries contain lead.
Recycling of batteries is the preferred method of 
disposal.
Many states require sellers of batteries to accept old 
batteries for recycling.
