Control and operation of radio transmitters
COMAND, 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 COMAND (Cockpit Management and Data
System), 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) every second.
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.

225 Tele Aid
Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index During this time you will hear a chirp and voice contact
will be interrupted. Voice contact will resume once the
retransmission is completed. Once a call is concluded, a
chirp will be heard and the appropriate indicator lamp
will stop flashing. The COMAND system operation will
resume.
Important!
If the indicator lamp continues to flash or the system
does not reset, contact the Response Center at
1-800-756-9018 (in the USA) or 1-888-923-8367 (in
Canada), or Mercedes-Benz Customer Assistance at
1-800-FOR-MERCedes (1-800-367-6372) in the USA or
Customer Service at 1-800-387-0100 in Canada.Notes:
The indicator lamp in the respective button flashes until
the call is concluded. Calls can only be terminated by a
Response Center or Customer Assistance Center
representative except Roadside Assistance and
Information calls, which can also be terminated by
pressing ìbutton on the multifunction steering
wheel.
When a Tele Aid call has been initiated, the COMAND
system audio is muted and the selected mode (radio,
tape or CD) pauses. The optional cellular phone (if
installed) switches off. If you must use this phone, the
vehicle must be parked. Disconnect the coiled cord and
place the call. The navigation system (if engaged) will
continue to run. The display in the instrument cluster is
available for use and spoken commands are only
available by pressing the RPT button on the COMAND
unit. A pop-up window will appear in the COMAND
display to indicate that a Tele Aid call is in progress.

•Do not forget, the engine can be started by anyone if
a KEYLESS-GO-card is left inside the vehicle.
•To be able to operate the vehicle in the case of a
malfunction in the KEYLESS-GO-system (e.g. strong
radio frequency disturbance), we recommend that
you carry the electronic key plus mechanical key
with you and keep them in a safe place so that they
are always handy. Never leave the electronic key in
the vehicle.
•To avoid radio transmission interference, never store
the KEYLESS-GO-card together with other electronic
items (e.g. cellular telephones, other KEYLESS-GO-
cards) or metallic objects (e.g. coins, metal foil).Notes:
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example:
Heated seats, rear window defroster. In addition, the
automatic climate air volume control should be set to
the lowest position.

1 One or more tires is or has deflated rapidly. Carefully bring the
vehicle to a halt, avoiding abrupt steering and braking maneuvers.
For reference on changing wheels, see page 348.
2 The tire pressure on one or more tires is already below minimum
value. Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers. For reference on changing
wheels, see page 351.
3 For tire inflation pressure monitor, see page 152.4 Tire pressure in one or more tires is low. Check and correct tire
pressure according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 356.
The tire inf lation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 152.
5 When the message appears after starting the engine, the tire
inflation pressure on all road wheels should be checked and
corrected according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 356.
The tire inf lation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 152.
6 The tire inflation pressure monitor system is unable to monitor the
tire pressure due to the presence of several wheel electronics in
the vehicle (e.g. a deflated road wheel in the trunk), or nearby
radio interference source, or excessive wheel sensor temperatures,
or unrecognized wheel sensors mounted.
7 The tire inflation pressure monitor is defective or a wheel without
proper sensor was installed. Visit your authorized Mercedes-Benz
Center.Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the
ability to steer or brake the vehicle. You may lose
control of the vehicle. Continued driving with a flat
tire will cause excessive heat build-up and possibly
a fire.

CHIP-CARD (KEYLESS-GO)
* C = Category, see page 309.1 Check battery of KEYLESS-GO-card, see page 374.
2 The KEYLESS-GO-card cannot be recognized by the running
engine (e.g. strong radio-frequency interference) or the card is not
in the vehicle.
Stop immediately and search for the KEYLESS-GO-card or continue
to operate the vehicle with the electronic key, otherwise the vehicle
cannot be centrally locked or the engine started again after the
engine stops automatically. See page 36.
3 The KEYLESS-GO-card was momentarily not recognized. If
message repeats, place card in a different position or continue to
operate the vehicle with the electronic key, see page 36.
4 A KEYLESS-GO-card left inside the vehicle has been recognized
while locking the vehicle from the outside, see page 36.
5 The message appears for maximum of 60 seconds each time the
driver’s door is opened, as long as no electronic key is in the
starter switch. The message appears regardless of the past
operation method (electronic key or KEYLESS-GO-card), see
page 36. Line 1 Line 2 C*
