The area can be determined as either a circle
or a polygon with a maximum of ten corners.
You can specify up to ten areas
simultaneously. Different settings are
possible for each area.
USA only: these settings can be called up
under "Owners Online" at http://
www.mbusa.com.
Alternatively, you can trigger an MB Info call
and inform the customer service
representative that you wish to activate geo
fencing.
Currently inactive areas can be activated by
text message.

WARNING
The brush guard is designed solely to enhance
the appearance of the vehicle and help
protect grille and headlamps from minor
mishaps, either on or off road.
Since
the safety characteristics are limited in
the event of an accident, brush guard are not
intended to prevent injury or damage in the
event of an accident. Also observe state and
local regulations on installation and use. Raise and lower the brush guard in an open
space with plenty of room.
i If you wish to remove the brush guard,

Important safety notes G
WARNING
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent
potential harm or damage. When
programming
a garage door opener, the door
moves up or down. When programming a gate
operator, the gate opens or closes.
Do not use the integrated remote control with
any garage door opener that lacks safety stop
and reverse features as required by U.S.
federal safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the door
to stop and reverse - does not meet current
U.S. federal safety standards.
When programming a garage door opener,
park vehicle outside the garage.
Do not run the engine while programming the
integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide (CO),
and inhaling it can cause unconsciousness
and possible death. All exhaust gas contains
carbon monoxide (CO), and inhaling it can
cause unconsciousness and possible death.
You can use the HomeLink ®
