the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check which periodically establishes a radio
connection between the vehicle and the
SmartKey determines whether a valid Smart- Key is in the vehicle. This occurs, for example, when starting the engine.
To start the vehicle without actively using the
SmartKey:
R the Start/Stop button must be inserted in
the ignition lock.
R the SmartKey must be in the vehicle.
R the vehicle must not be locked with the
SmartKey or KEYLESS-GO (Y page 91).
Do not keep the SmartKey:
R with electronic devices, e.g. a mobile
phone or another SmartKey
R with metallic objects, e.g. coins or metal
foil
R inside metallic objects, e.g. a metal case
This can affect the functionality of the Smart- Key.
Do not keep the SmartKey in the tempera-
ture-controlled cup holder (Y page 380). Oth-
erwise, the SmartKey will not be detected,
e.g. when starting the engine with the Start/ Stop button.
If you lock the vehicle with the SmartKey's
remote control or with KEYLESS-GO, after a
short time:
R you will not be able to switch on the ignition
with the Start/Stop button.
R you will not be able to start the engine with
the Start/Stop button until the vehicle is
unlocked again.
If you lock the vehicle centrally using the but-
ton on the front door (Y page 97), you can
continue to start the engine with the Start/
Stop button. The engine can be turned off while the vehicle
is in motion by pressing and holding the
Start/Stop button for approximately three
seconds. This function operates independ-
ently of the ECO start/stop automatic engine switch-off function.

rials come into contact with parts of the vehi-cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields. G
WARNING
If you leave children unsupervised in the vehi- cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
! Always secure the vehicle correctly
against rolling away. Otherwise, the vehicle
or its drivetrain could be damaged.

Important safety notes G
WARNING
When you operate or program the garage door with 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 garage
door.
G
WARNING
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.

doing so, vary the distance between remote control Aand the rear-view mirror.
The required distance between remote
control Aand the integrated garage door
opener depends on the garage door drive
system. Several attempts might be neces-
sary. You should test every position for at
least 25 seconds before trying another
position.
Synchronizing the rolling code
Pay attention to the "Important safety notes"
(Y page 398).
If the garage door system uses a rolling code, you will also have to synchronize the garage
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 the
garage 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/
objects are present within the sweep of the
door or gate.
X Turn the SmartKey to position 2in the igni-
tion lock (Y page 189).
X Get out of the vehicle.
X Press the programming button on the door
drive unit.
Usually, you now have 30 seconds to ini-
tiate the next step.
X Get into the vehicle.
X Press previously programmed button ;,
= or? on the integrated garage door
opener until the door closes.
The rolling code synchronization is then
complete.
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 programming
steps

system. Several attempts might be neces-
sary. You should test every position for at
least 25 seconds before trying another

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 control
A 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
