Checking and relling levels
With the engine running
The battery may discharge despite the fact
that energy is being generated while the vehi-
cle is in motion. This is particularly the case if
too little energy is generated and too much is
consumed at a time while the battery's level of
charge is not optimal.
To restore the energy balance, the devices that
consume the most energy are either tempora-
rily adjusted or deactivated. Heating systems,
in particular, consume a lot of energy. If you
notice, for instance, that the seat heating or
the rear window heater is not working, they
may have been temporarily switched o or
regulated to a lower heat output. These sys-
tems can be used again as soon as the energy
balance has been restored.
If necessary, you may also notice a slight
idling speed boost. However, this is normal and
should not cause you any concern. Boosting
the idling speed generates additional energy
and charges the battery.
