Notes on the battery main switch
*
NOTE Damaged to control units and
cooled component parts
When the main battery switch is removed
immediately, cooling of important component
parts and the storage of parameters in the
control units can be interrupted. This can sig-
nificantly reduce the service life of component
parts and control units.
#
Make sure that vehicle is switched off.
Then wait at least 20 minutes before
removing the battery main switch.
You can use the battery main switch to disconnect
the current to all your vehicle's consumers. This
will prevent uncontrolled battery discharge caused
by quiescent current consumers.
If your vehicle is equipped with an auxiliary battery
in the engine compartment or in the base of the
front passenger seat, you must disconnect both
batteries. Only then will the electrical system be
fully disconnected from the power supply.
