WARNING
When you charge a battery, hydrogen is released, and a highly explosive
■
gas mixture is also produced. An explosion can be caused through sparkling
over during unclamping or loosening of the cable plug while the ignition is
on.
Creating a bridge between the poles on the battery (e.g. with metal ob-
■
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
Avoid creating sparks when working with cables and electrical devices.
■
Strong sparking represents a risk of injury.
Before carrying out any work on the electrical system, switch off the en-
■
gine, the ignition and all electrical consumers and disconnect the negative
terminal .
"Quick-charging" the vehicle battery is dangerous and requires a special
■
charger and specialist knowledge.
We therefore recommend that vehicle batteries be "rapidly charged" by a
■
specialist garage.
CAUTION
On vehicles with the START/STOP system or additional heating (auxiliary heat-
ing), the pole terminal of the charger must not be connected directly to the
negative terminal of the vehicle battery, but only to the engine earth

Replacing

Read and observe and
The new vehicle battery must have the same capacity, voltage, current and the
same size as the original battery. Suitable vehicle battery types can be pur-
chased from a specialist garage.
We recommend that the battery is replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations.

tions or devices are partially or completely inoperative.
Function / device
Electric window levers
Radio
Time settings
CAUTION
Disconnect the vehicle battery only with the ignition turned off - there is a
■
risk of damaging the electrical system of the vehicle.
Under no circumstances must the battery cables be connected incorrectly –
■
risk of a cable fire.
Note
After disconnecting and re-connecting the vehicle battery, we recommend
■
having the vehicle checked by a specialist to ensure that the full functionality
of all electrical systems is guaranteed.
The data of the multi-function display will be reset.

Automatic load deactivation

Read and observe and
The vehicle voltage control unit automatically prevents the battery from dis-
charging when the battery is subjected to heavy loads. This may be noticed
from the following.
›
The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
›
Where appropriate large convenience consumers, e.g. seat heaters, rear win-
dow heaters, have their power limited or shut off completely if necessary.
