Tele Aid The Tele Aid system
(Tele

mand)
The Tele Aid system consists of three
types of response:
automatic and manual emergency
roadside assistance, and
information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the multifunction steering wheel. To
raise, press buttonæ and to lower,
press buttonç.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
!The initial activation of the Tele Aid sys-
tem may only be performed by com-
pleting 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 the
SmartKey in starter switch to
position2, or pressing the
KEYLESS-GO* start/stop button twice
to position2 . The message
TELE AID –
NOT ACTIVATED
will be shown in the
multifunction display for approximately
ten seconds.
If you have any questions regarding ac-
tivation, please call the Response Cen-
ter at 1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada).

Upgrade Signals
The Tele Aid system processes calls using
the following priority:
Automatic emergency – First priority
Manual emergency – Second priority
Roadside Assistance – Third priority
Information – Fourth priority
Should a higher priority call be initiated
while you are connected, an upgrade (al-
ternating) tone will be heard, and the ap-
propriate indicator lamp will flash. If
certain information such as vehicle identi-
fication number or customer information is
not available, the operator may need to re-
transmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retransmis-
sion is completed. Once a call is conclud-
ed, a beep will be heard and the respective
indicator lamp will stop flashing. The
COMAND system operation will resume.
iThe indicator lamp on the Information
button¡ remains illuminated in red
for approximately ten seconds during
the system self-check after turning the
ignition on (together with the SOS but-
ton and the Roadside Assistance
button•).
See System self-check (
page 243)
when the indicator lamp does not come
on in red or stays on longer than ap-
proximately ten seconds.
If the indicator lamp in the Information
button¡ is illuminated continuous-
ly and no voice connection to the Re-
sponse Center was established, then
the Tele Aid system could not initiate
an Information call (e.g. the relevant
cellular phone network is not avail-
able). The message
INFO –
CALL FAILED
appears in the multifunc-
tion display.
Information calls can be terminated us-
ing the tbutton on the multifunc-
tion steering wheel.!If the indicator lamps do not start flash-
ing after pressing one of the buttons or
remain illuminated (in red) at any time,
the Tele Aid system has detected a
fault or the service is not currently ac-
tive, and may not initiate a call. Visit an
Mercedes-Benz Center and have the
system checked or contact the Re-
sponse Center at 1-800-756-9018 (in
the USA) or 1-888-923-8367 (in Cana-
da) as soon as possible.
262 OperationDriving instructions
Tires
Tread wear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1⁄16 in (1.6 mm), at which point the
tire is considered worn and should be re-
placed.The tread wear indicator appears as a solid
band across the tread.
Specified tire pressures must be main-
tained. This applies particularly if the tires
are subject to extreme operating condi-
tions (e.g. high speeds, heavy loads, high
ambient temperatures).
Turn the SmartKey to starter switch
position0 and remove, or press
KEYLESS-GO* start/stop button.
Take the SmartKey or the SmartKey with
KEYLESS-GO
* with you and lock vehicle
when leaving.
!Set the parking brake whenever park-
ing or leaving the vehicle. In addition,
move gear selector lever to positionP.
When parking on hills, always turn front
wheels towards the road curb.
Warning!
G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tion to an area which is a safe distance from
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have it towed to the nearest
Mercedes-Benz Center or tire dealer for re-
pairs.
Warning!
G
Although the applicable federal motor vehi-
cle safety laws consider a tire to be worn
when the tread wear indicators (TWI) be-
come visible at approximately
1⁄16 in
(1.6 mm), we recommend that you do not al-
low your tires to wear down to that level. As
tread depth approaches
1⁄8 in (3 mm), the
adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
