WarningG
The driver should not operate any of the
Rear Audio features at the Rear climate
control panel while driving the vehicle under
any circumstances. These features can
distract the driver from traffic conditions
and should only be operated by the rear seat
occupants.
Similarly, the driver should not wear a Rear
Audio headset while operating the vehicle
under any circumstances. The use of a
headset while driving the vehicle could
drastically impair the ability to react to
audible traffic conditions (e.g. emergency
sirens from police/fire/ambulance, another
drivers horn, etc).
WarningG
When not in use, headsets should be stored
in a safe location (e.g. one of the vehicle’s
storage compartments) so that they are not
loose within the passenger compartment
during braking, vehicle maneuvers or a
traffic accident. Objects moving within the
passenger compartment could cause
serious personal injury to vehicle
occupants.
WarningG
Due to a potential choking hazard, wired
headset usage by children should only occur
with adult supervision.
i
Only use 32 Ohm headsets.

an authorized Mercedes-Benz Center.
