Automatic Load Deactivation - KODA Citigo Owner's Manual

It is not normally necessary to disconnect the cables of the battery if you re-
charge the vehicle battery using low amperages (as for example from a mini-
charger). Refer to the instructions of the charger manufacturer.
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower)
must be used until full charging is achieved.
It is, however, necessary to disconnect both cables before charging the battery
with high amperages, so-called "quick-charging".
"Quick-charging" the vehicle battery is dangerous and requires a special charger
and specialist knowledge. We therefore recommend that vehicle batteries be
quick-charged by a specialist garage.
The vent plugs of the vehicle battery should not be opened for charging.
CAUTION
On vehicles with the START/STOP system, 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 » page 146, Jump-starting in vehicles with the START-STOP
system.

Replacing the vehicle battery

First read and observe the introductory information and safety warn-
ings on page 127.
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable vehicle battery types can be
purchased from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be dis-
posed of in accordance with national regulations.

Automatic load deactivation


First read and observe the introductory information and safety warn-
ings on page 127.
The vehicle voltage control unit automatically prevents the battery from discharg-
ing when the battery is put under high levels of strain. This manifests itself by the
following:
›
The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
›
Where necessary, large convenience consumers such as seat heaters and rear
window heaters have their power limited or are shut off completely in the event
of an emergency.
CAUTION
Despite such intervention by the vehicle electric system management, the vehi-
■
cle battery may be drained. For example, when the ignition is switched on a long
time with the engine turned off or the side or parking lights are turned on during
longer parking.
Consumers that are supplied via a 12-V power socket can cause the vehicle bat-
■
tery to discharge when the ignition is switched off.
Note
Driving comfort is not impaired by consumers being deactivated. The driver is of-
ten not aware of it having taken place.
