KEYLESS-GO
Important!
For the KEYLESS-GO-system to function properly, the 
operator should observe the following:
•The driver should carry the KEYLESS-GO-card with 
him / her.
•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).
•To lock or unlock the vehicle, the card must be 
recognized by the system as being located outside 
the vehicle. The card must be in close proximity to a 
door or the trunk lid (approx. 3 ft. [1 m]). To activate 
the start / stop button function, the KEYLESS-GO-
card must be recognized by the system as being 
located inside the vehicle.
•If the KEYLESS-GO-card is positioned farther away 
from the vehicle (e.g. inside clothing or a briefcase) 
and can no longer be recognized by the system, the 
vehicle cannot be locked or the engine started via 
the KEYLESS-GO-system.•If the KEYLESS-GO-card is removed from the vehicle 
while the engine is running, or by placing the card 
in front of the center armrest (see page 195), the 
message “CHIP-CARD – NOT RECOGNIZED!” will 
appear repeatedly in the multifunction display, 
seepage322.
Find the card or change its present location (e.g. 
place it on the front passenger seat or insert it in 
shirt pocket).
•If the message “CHIP - CARD – NOT RECOGNIZED” 
is ignored for an extended of time (approx. 
15 minutes), the engine could stop by itself during a 
vehicle stop (e.g. traffic light). The vehicle can then 
no longer be centrally locked or the engine 
restarted. You must first find the card or change its 
present location (e.g. place it on the front passenger 
seat or insert it in shirt pocket). Start the engine 
again. See page 228.
•Do not forget, the engine can be started by anyone 
with a KEYLESS-GO-card that is left inside the 
vehicle. Leaving the chip-card behind when exiting 
and locking the vehicle, the message “CHIP-CARD –
STILL IN VEHICLE” appears in the multifunction 
display, see page 322.

a 31.5 in  ( 8 0 c m )
b19.0in (48cm)
c 1.75 in (4.5 cm)Your vehicle is equipped with infrared reflecting glass 
which reduces the amount of radiated heat entering the 
interior through the windows.
The infrared reflecting glass also prevents the 
transmission of signals through the glass by in-vehicle 
electronic devices (e.g. electronic toll collection 
devices).
To allow the use of these devices in the vehicle, two 
infrared transparent areas (1 and 2) are placed in the 
windshield.

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 Client 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 Client 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.
