Driving systems
Driving systems
The driving system of your vehicle is
described on the following pages:
Cruise control, with which the vehicle
can maintain a preset speed
For information on the BAS, ABS and ESP
®,
see “Driving safety systems” (
page 81).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set or resume the
cruise control at any speed over 20 mph
(30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever on the left-hand side of the steering
column (
page 30).
Warning!G
The Cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.
The use of the cruise control can be dan-
gerous on winding roads or in heavy traf-
fic because conditions do not allow safe
driving at a steady speed.
The use of the cruise control can be dan-
gerous on slippery roads. Rapid changes
in tire traction can result in wheel spin
and loss of control.
Deactivate the cruise control when
driving in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

ation (e.g. for passing), the cruise control will re-

Tele Aid
Shortly after the completion of your Tele
Aid acquaintance call, you will receive a
user ID and password. By visiting
www.mbusa.com and selecting “Tele Aid”
(USA only), you will have access to account
information, remote door unlock, and
more.The Tele Aid system
(Tele
matic Alarm Identification on

The Tele Aid system consists of three
types of response:
Automatic and manual emergency
Roadside Assistance
Information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and
cellular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the audio system or on the multifunc-
tion steering wheel. To raise, turn the rota-
ry volume control on the audio system
clockwise or press buttonæ on the
multifunction steering wheel. To lower,
turn the rotary volume control on the audio
system control counterclockwise or press
buttonç on the multifunction steering
wheel.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.
!The initial activation of the Tele Aid system
may only be performed by completing the sub-
scriber agreement and placing an acquaintance
call using the ¡button. Failure to complete
either of these steps will result in a system that
is not activated.
If you have any questions regarding activation,
please call the Response Center at
1-800-756-9018 (in the USA) or
1-800-387-0100 (in Canada).
iThe SOS button is located above the inside
rear view mirror (
page 217).
The Roadside Assistance button•
(
page 217) and the Information button¡
(
page 218) are located in the center storage
compartment.
!The Tele Aid system utilizes the cellular net-
work for communication and the GPS (
Global Po-
sitioning
System) satellites for vehicle location.
If either of these signals are unavailable, the Tele
Aid system may not function and if this occurs,
assistance must be summoned by other means.
iWhen a Tele Aid call has been initiated, the
audio system is muted and the selected mode
(radio or CD) pauses. The mobile phone (if in-
stalled) switches off. If you must use this phone,
we recommend that you use it only with the ve-
hicle at a standstill in a safe location. Remove
the phone from the cradle and place the call. The
multifunction display in the instrument cluster is
available for use. After the Tele Aid call has end-
ed, the optional mobile phone switches on again.
A PIN entry might be necessary.

tion number and color are generated.
A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon
after the emergency call has been initiat-
ed. The Response Center will attempt to
determine more precisely the nature of the
accident provided they can speak to an
