Control and operation of radio transmitters
Radio and telephone
1 Observe all legal requirements.
Telephones and two-way radio
Radio transmitters, such as a portable telephone or a
citizens band unit should only be used inside the
vehicle if they are connected to an antenna that is
installed on the outside of the vehicle.
Refer to the radio transmitter operation instructions
regarding use of an external antenna.
Wa r n i n g !
Please do not forget that your primary
responsibility is to drive the vehicle. Only operate
the radio or telephone
1 if road 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 approximately 50 feet (approximately
14 m ) e v e r y s e c o n d .
Wa r n i n g !
Never operate radio transmitters equipped with a
built-in or attached antenna (i.e. without being
connected to an external antenna) from inside the
vehicle while the engine is running. Doing so could
lead to a malfunction of the vehicle’s electronic
system, possibly resulting in an accident and
personal injury.

The more cautiously you treat your vehicle during the
break-in period, the more satisfied you will be with its
performance later on. Therefore, drive your vehicle
during the first 1 000 miles (1 500 km) at moderate
vehicle and engine speeds.
During this period, avoid heavy loads (full throttle
driving) and excessive engine speeds.
Manual transmission:
Downshift at proper engine speeds.
Automatic transmission:
Avoid accelerating by kickdown. It is not recommended
to bra ke t he veh icl e by ma nu al ly shif ting to a l owe r gear.
We recommend that you select positions “3”, “2” or “1”
only at moderate speeds (for hill driving).
After 1 000 miles (1 500 km) speeds may be gradually
increased to the permissible maximum.Maintenance
Approximately 30 days or 2000 miles (2000 km) prior to
the next recommended service, the remaining distance
or days are displayed in the main odometer field. See
Flexible service system (FSS) on page 75.
We strongly recommend that you have your vehicle
serviced by your authorized Mercedes-Benz Center, in
accordance with the Service Booklet at the times called
for by the FSS.
Failure to have the vehicle maintained in accordance
with the Service Booklet at the designated times /
mileage may result in vehicle damage not covered by

Te l e A i d
Important!
The initial activation of the Tele Aid system may only be
performed by completing the subscriber agreement and
placing an acquaintance call using the “SOS” button.
Failure to complete either of these steps will result in a
system that is not activated. If the system is not
activated the indicator lamp in the “SOS” button stays
on after turning electronic key in starter switch to
position 2.
If you have any questions regarding activation, please
call the Response Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
(Te l ematic Alarm Identification on Demand)
The Tele Aid system consists of three types of response;
automatic and manual emergency, roadside assistance
and information.
The Tele Aid system is operational providing that the
vehicle’s battery is charged and properly connected, not
damaged and cellular and GPS coverage is available. To
activate, press the “SOS” button, the Roadside
Assistance button or the Information button¡,
depending on the type of response required.Shortly after the completion of your Acquaintance Call,
you will receive a user ID and password via first call
mail. By visiting www.mbusa.com and selecting
“Tele Aid” (USA only), you will have access to account
information, remote door unlock and more.
System self-check
Initially, after turning the key in steering lock to
position 2, malfunctions are detected and indicated (the
indicator lamps in the “SOS” button, the Roadside
Assistance button and the Information
button¡ stay on longer than 10 seconds or do not
come on).
Important!
Always make sure that the indicator lamps in the
“SOS” button, in the “Roadside Assistance” button and
in the “Information” button do not remain illuminated
constantly in red after the system self check.
If a malfunction is indicated as outlined above, have the
system checked at the nearest Mercedes-Benz Center as
soon as possible.
