To help avoid personal injury during a collision or
sudden maneuver, exercise care when stowing
things. Put luggage or cargo in the trunk if
possible. Do not pile luggage or cargo higher than
the seat backs. Do not place anything on the shelf
below the rear window.Luggage nets cannot secure hard or heavy objects. Wa r n i n g !
Keep compartment lids closed. This will help to
prevent stored objects from being thrown about
and injuring vehicle occupants during an accident.

rear seat, deactivate the operation of rear door
windows, see page 186. Deactivation of the rear
windows also deactivates the lighter.When leaving the vehicle always remove the
electronic key from the starter switch. Do not leave
children unattended in the vehicle, or with access
to an unlocked vehicle. Unsupervised use of vehicle

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 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.

Te ch n i c a l

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.

cluster displayPractical hints Car care Index Important!
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.
If the electronic key cannot be turned in the starter
switch, the vehicle battery may not be sufficiently
charged. See battery on page 357 or jump starting on
page 359.
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:
