Control system
Introduction
The control system is activated as soon as the
starter switch is in position 1 (Y page 62).
The control system enables you to call up
information about your vehicle and to change
vehicle settings.
For example, you can use the control system
to find out when your vehicle is next due for
maintenance service, to set the language for
messages in the instrument cluster display,
and much more.
GWarning!
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.
The control system relays information to the
multifunction display.
Multifunction steering wheel
The displays in the multifunction display and
the settings in the control system are
controlled by the buttons on the multifunction
steering wheel.

The Tele Aid system
(Telematic Alarm Identification on Demand)
The Tele Aid system consists of three types
of response:
RAutomatic and manual emergency
RRoadside Assistance
RInformation
The Tele Aid system is operational providing
that the vehicle’s battery is charged, properly
connected, not damaged, and cellular and
GPS coverage is available. The Tele Aid
system utilizes the cellular network for
communication and the GPS (Global
Positioning 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.
i A Tele Aid call cannot be canceled. Even
if the Tele Aid system is not activated or
operational, the system will attempt to
connect the respective call. This may take
as long as 5 minutes or more. As long as
the Tele Aid system attempts to connect a
call, you cannot operate the audio system
or the COMAND system. Also, most
functions in the control system, such as the
telephone function, are suspended.
Therefore, it is not advisable to initiate any
Tele Aid call unless the Tele Aid system is
activated and operational.

Garage door opener
The integrated remote control can operate up
to three separately controlled devices
compatible with HomeLink® or some other
systems.
GWarning!
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent
potential harm or damage. When
programming a garage door opener, the door
moves up or down. When programming a gate
operator, the gate opens or closes.
Do not use the integrated remote control with
any garage door opener that lacks safety stop
and reverse features as required by U.S.
federal safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the door
to stop and reverse - does not meet current
U.S. federal safety standards.
When programming a garage door opener,
park vehicle outside the garage.
Do not run the engine while programming the
integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide (CO),
and inhaling it can cause unconsciousness
and possible death.
