Important safety notes
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi- cle while driving, you will be distracted from
traffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for
the country in which you are currently driving when operating COMAND.
COMAND calculates the route to the destina-
tion without taking account of the following,
for example:
R traffic lights
R stop and yield signs
R merging lanes
R parking or stopping in a no parking/no
stopping zone
R other road and traffic rules and regulations
R narrow bridges
COMAND can give incorrect navigation com-
mands if the actual street/traffic situation
does not correspond with the digital map's
data. Digital maps do not cover all areas nor
all routes in an area. For example, a route may have been diverted or the direction of a one-
way street may have changed.
For this reason, you must always observe
road and traffic rules and regulations during
your journey. Road and traffic rules and reg-
ulations always have priority over the sys-
tem's driving recommendations.

Important safety notes
GWARNING
When you operate or program the garage doorwith the integrated garage door opener, per-
sons in the range of movement of the garage
door can become trapped or struck by the
garage door. There is a risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garagedoor.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.

door system with the integrated garage door
opener in the rear-view mirror. To do this you
will need to use the programming button on
the door drive control panel. The program-
ming button may be positioned at different
locations depending on the manufacturer. It
is usually located on the door drive unit on thegarage ceiling.
Familiarize yourself with the garage door
drive operating instructions, e.g. under "Pro-
gramming of additional remote controls",
before carrying out the following steps.
Your vehicle must be within reach of the
garage door or gate opener drive. Make sure
that neither your vehicle nor any persons/

Notes on programming the remote con-
trol
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds. Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers also fea-
ture a "break". Proceed as follows:
R if you live in Canada
R if you have difficulties programming the
garage door opener (regardless of where
you live) when using the programmingsteps

Problems when programming
If you are experiencing problems programing
the integrated garage door opener on the
rear-view mirror, take note of the following
instructions:
R Check the transmitter frequency used by
garage door drive remote control Aand
whether it is supported. The transmitter
frequency can usually be found on the back
of the garage door drive remote control.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
R Replace the batteries in garage door
remote control A. This increases the like-
lihood that garage door remote control A
will transmit a strong and precise signal to
the integrated garage door opener.
R When programming, hold remote controlA at varying distances and angles from the
button which you are programming. Try var- ious angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
R If another remote control is available for the
same garage door drive, repeat the same
programming steps with this remote con-
trol. Before performing these steps, make
sure that new batteries have been installed
in garage door drive remote control A.
R Note that some remote controls only trans-
mit for a limited amount of time (the indi-
cator lamp on the remote control goes out).
Press button Bon remote control Aagain
before transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal recep-tion/transmission.
Opening/closing the garage door
After it has been programmed, the integrated
garage door opener performs the function of
the garage door system remote control. Please also read the operating instructions
for the garage door system.
X Turn the SmartKey to position 2in the igni-
tion lock ( Ypage 115).
X Press button ;,= or? which you have

long as the button is pressed. The trans-
mission is halted after a maximum of ten
seconds and indicator lamp :lights up
yellow.
X Press button ;,= or? again if neces-
sary.
Clearing the memory
Make sure that you clear the memory of the
integrated garage door opener before selling
the vehicle.

GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
