116 Inspecting and replenishing
Operation in winter
The vehicle battery has to provide greater amounts of electricity during the win-
ter. It also has only part of the initial power output at low temperatures that it has
at normal temperatures.
A discharged vehicle battery may already freeze at temperatures just below 0
°C.
We therefore recommend that you have the battery checked by a specialist ga-
rage before the start of the winter, and recharged if necessary.
WARNING
Never charge a frozen or thawed vehicle battery - risk of explosion and caustic
burns! Replace a vehicle battery that is frozen.
Charging a vehicle battery
A properly charged vehicle battery is essential for reliably starting
the engine.
Read the warning notes ⇒
–
Switch the ignition and all electrical components off.
–
– Only for "quick-charging": Disconnect both battery cables (first of all "nega-
tive", then "positive").
Carefully attach the terminal clamps of the charger to the battery terminals
–
(red = "positive", black = "negative").
You can now plug the mains cable of the charger into the power socket and
–
switch on the charger.
When charging is completed: switch the charger off and unplug the mains ca-
–
ble from the power socket.
– Only then should you disconnect the terminal clamps of the charger.
Reconnect the cables to the battery (first of all "positive", then "negative").
–
It is not normally necessary to disconnect the cables of the battery if you recharge
the vehicle battery using low amperages (as for example from a mini-charger).
Please also refer to the instructions from the charger manufacturer.
in General information on page 114 and ⇒
A charging current of 0.1 of the total vehicle battery capacity (or lower) is that
which should 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".
WARNING
● Never charge a frozen or thawed vehicle battery - risk of explosion and
caustic burns! Replace a vehicle battery that is frozen.
● Never charge a vehicle battery which has a too low electrolyte level - risk
of explosion and caustic burns.
● "Quick-charging" a vehicle battery is dangerous. It requires a special charg-
er and specialist knowledge. We recommend having the quick charging of ve-
hicle batteries undertaken by a specialist garage.

● A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C. We recommend that you no longer use a vehicle battery which has
thawed out because the casing of the battery may be cracked through the for-
mation of ice and this would allow battery electrolyte to flow out.
● 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 ⇒ p age 135.
Disconnecting and reconnecting the vehicle battery
On disconnecting and reconnecting the vehicle battery the following functions are
initially deactivated or are no longer able to operate fault-free.
Operation
Enter radio code number
Setting the clock
Data in the multi-functional indicator are de-
leted.
Note
We recommend having the vehicle checked by an authorised ŠKODA Service Part-
ner to ensure full functionality of all electrical systems.
