Risk of injury

You could injure yourself on sharp-edged
frame parts or reinforcement materials dur-
ing installation.
For this reason, have the peripherals
installed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
!
Before installing a device, you must
connect the quiescent current reten-
tion unit and disconnect the battery
earthing line.

The 12 volt power supply connection is
only supplied with power by the battery
when the key is in position

connection is protected by the PSM
module.
If the vehicle battery voltage falls below
11.2 V, the 12 volt power supply con-
nection switches off.
