Telephone*
Radio transmitters, such as a portable tele-

the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-

tion on the installation of an approved
external antenna. Refer to the radio trans-
mitter operation instructions regarding use

ment.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)

sibly resulting in an accident and/or serious
personal injury.

should be repaired promptly. Otherwise, exces-
sive unburned fuel may reach the catalytic con-
verter, causing it to overheat, which could
potentially start a fire.
