Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.!If the rear window defroster switches
off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.

In order to help prevent spilling liquids on
vehicle occupants, only use containers that
fit into the cup holder. Use lids on open con-
tainers and do not fill containers to a height
where the contents, especially hot liquids,
could spill during braking, vehicle maneu-
vers, or in an accident.
When not in use, keep the cup holder
closed. An open cup holder may cause injury
to you or others when contacted during
braking, vehicle maneuvers, or in an acci-
dent.
Keep in mind that objects placed in the cup
holder may come loose during braking, vehi-
cle maneuvers, or in an accident and be
thrown around in the vehicle interior. Ob-
jects thrown around in the vehicle interior
may cause an accident and/or serious per-
sonal injury.

254 Controls in detailUseful featuresTelephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Center for informa-
tion on the installation of an approved
external antenna. Refer to the radio trans-
mitter operation instructions regarding use
of an external antenna.You can take and place telephone calls us-
ing thes andt buttons on the
steering wheel. To carry out other tele-
phone functions, use the control system
(
page 143).
See separate operating manual for instruc-
tions on how to use the telephone.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or serious
personal injury.
Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle. A driver’s
attention to the road must always be
his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call.
If you choose to use the telephone
1 while
driving, please use the hands-free device
and only use the telephone when road,
weather and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
cellular telephone while driving a vehicle.
Only operate the COMAND (Cockpit Man-
agement and Data System)
1 if road, weather
and traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.

Warning!
G
Before programming the integrated remote
control to a garage door opener or gate op-
erator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage.
When programming a garage door opener,
the door moves up or down. When program-
ming a gate operator, the gate opens or
closes.
Do not use the integrated remote control
with any garage door opener that lacks safe-
ty stop and reverse features as required by
U.S. federal safety standards (this includes
any garage door opener model manufac-
tured 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.
