Important safety notes G WARNING During the charging process, a battery produ- ces hydrogen gas. If a short circuit occurs or sparks are created, the hydrogen gas can ignite. There is a risk of an explosion.
G WARNING Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo- sive gases of a battery. There is a risk of an explosion. Before handling the battery, touch the vehicle body to remove any existing electrostatic build-up. Maintenance and care R Make sure that the positive terminal of a connected battery does not come into con- tact with vehicle parts. R Never place metal objects or tools on a bat- tery. A highly explosive mixture of gases is gener- ated while charging the battery and jump- starting. Always make sure that neither you nor the battery are electrostatically charged. An elec- trostatic build-up may occur, for example:

Avoid contact with skin, eyes or clothing. Do not inhale any gases released from the bat- tery. When carrying out maintenance work on the battery, wear acid-resistant protective clothing, particularly protective eyewear, pro- tective gloves and an apron. Do not lean over the battery. Keep the batteries out of the reach of children. Batteries contain pollutants. It is against the law to dis- pose of them along with household waste. They must be collected separately and recycled in an environmen- tally responsible manner. Dispose of batteries appro- priately. Hand over dis- charged batteries to a quali- fied specialist workshop. Transport and store full bat- teries in an upright position.
