Overloading the starter battery

The electrical functions in the car load the
starter battery to varying degrees. Avoid
using the ignition position II when the car is
switched off. Instead, use ignition position I -
which uses less power.
Also, be aware of different accessories that
load the electrical system. Do not use func-
tions which use a lot of power when the car is
switched off. Examples of such functions are:
ventilation fan
•
headlamps
•
windscreen wiper
•
audio system (high volume).
•
If the starter battery voltage is low, a message
is shown in the driver display. The energy-sav-
ing function then shuts down certain functions
or reduces certain functions such as the venti-
lation fan and/or audio system.
In which case, charge the starter battery
–
by starting the car and then running it for
at least 15 minutes - starter battery charg-
ing is more effective during driving than
running the engine at idling speed while
stationary.
