51.75 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.

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.

cluster displayPractical hints Car care Index Emission control
Certain systems of the engine serve to keep the toxic 
components of the exhaust gases within permissible 
limits required by law. 
These systems, of course, will function properly only 
when maintained strictly according to factory 
specifications. Any adjustments on the engine should, 
therefore, be carried out only by qualified Mercedes-
Benz Center authorized technicians. Engine 
adjustments should not be altered in any way. Moreover, 
the specified service jobs must be carried out regularly 
according to Mercedes-Benz servicing requirements. 
For details refer to the Service Booklet.
Wa r n i n g !
Inhalation of exhaust gas is hazardous to your 
health. All exhaust gas contains carbon monoxide, 
and inhaling it can cause unconsciousness and 
lead to death.Do not run the engine in confined areas (such as a 
garage) which are not properly ventilated. If you 
think that exhaust gas fumes are entering the 
vehicle while driving, have the cause determined 
and corrected immediately. If you must drive under 
these conditions, drive only with at least one 
window fully open.

If the electronic key is left in the starter switch 
position 0 for an extended period of time, it can no 
longer be turned in the lock. In this case, remove 
electronic key from starter switch and reinsert.
Caution!
To prevent accelerated battery discharge and a possible 
dead battery, always remove the electronic key from the 
starter switch. Do not leave the electronic key in starter 
switch position 0.Notes:
A warning sounds when the driver’s door is opened 
with the electronic key in starter switch position 1 or 0.
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.

•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:

Winter driving instructions
The most important rule for slippery or icy roads is to 
drive sensibly and to avoid abrupt acceleration, braking 
and steering maneuvers. Do not use the cruise control 
system under such conditions.
When the vehicle is in danger of skidding, move 
selector lever to position “N”. Try to keep the vehicle 
under control by corrective steering action.
Road salts and chemicals can adversely affect braking 
efficiency. Increased pedal force may become necessary 
to produce the normal brake effect. We therefore 
recommend depressing the brake pedal periodically 
when traveling at length on salt-strewn roads. This can 
bring road salt impaired braking efficiency back to 
normal. A prerequisite is, however, that this be done 
without endangering other drivers on the road.If the vehicle is parked after being driven on salt treated 
roads, the braking efficiency should be tested as soon as 
possible after driving is resumed while observing the 
safety rules in the previous paragraph.
Wa r n i n g !
If the vehicle becomes stuck in snow, make sure 
that snow is kept clear of the exhaust pipe and 
from around the vehicle with engine running. 
Otherwise, deadly carbon monoxide (CO) gases may 
enter vehicle interior resulting in unconsciousness 
and death.To assure sufficient fresh air ventilation, open a 
window slightly on the side of the vehicle not 
facing the wind.
