WARNING
If the power supply is interrupted with the
battery isolator switch, the engine is switched
off automatically. Safety-relevant functions
may therefore be restricted or unavailable,
e.g. power steering, lighting system and ABS.
The compressed-air supply fails. To steer, you
will require considerably more force. The
wheels could lock during braking. Also, the
spring-loaded parking brake can activate if
there is a loss of compressed air and the vehi-
cle may then brake uncontrollably. You could
lose control of the vehicle. There is a risk of an
accident.
Only use the battery isolator switch when the
vehicle is stationary.
Example: battery isolator switch
You can interrupt the voltage supply using the
battery isolator switches. This prevents short
circuits, which could create sparks that might
in turn cause a fire or an explosion. Depend-
ing on the ADR classification, vehicles for the
transport of hazardous goods can be equip-
ped with 2 battery isolator switches.
When you have safely parked the vehicle, you
can use the battery isolator switch, e.g. when
loading the vehicle in a hazardous goods area.
Only use the battery isolator switch when the
vehicle is stationary. Observe the notes in the
event window in the on-board computer.
Move the ignition lock to position 0 and
remove the key from the key switch. On vehi-
cles with a retarder, wait approximately
5 seconds after switching the ignition off
before interrupting the voltage supply using
the battery isolator switch. If the auxiliary
heating is switched on, wait for the auxiliary
heating run-on phase to end.
In a hazardous situation, the voltage supply
can be interrupted using the battery isolator
switches.
If the voltage supply is interrupted by the bat-
tery isolator switch when the anti-theft alarm
system is primed, the anti-theft alarm is trig-
gered.
