Overloading the starter battery

The electrical functions in the car load the starter
battery to varying degrees. Avoid using the igni-
tion position II when the engine 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 functions which
use a lot of power when the engine is switched
off. Examples of such functions are:
•
ventilation fan
•
headlamps
•
windscreen wiper
•
audio system (high volume).
If the starter battery voltage is low, the message
Low battery charge Will soon enter power
save mode is shown in the driver display. The
energy-saving function then shuts down certain
functions or reduces certain functions such as
the ventilation fan and/or audio system.
– In which case, charge the starter battery by
starting the engine and then running it for at
least 15 minutes - starter battery charging is
more effective during driving than running
the engine at idling speed while stationary.

consumption is normal

pressure
