KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped with a
SmartKey featuring an integrated KEYLESS-GO
function and a detachable Start/Stop button. A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different Smart-
Key positions in the ignition lock. This is only 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.
To start the vehicle without actively using the
SmartKey:
Rthe Start/Stop button must be inserted in the
ignition lock
Rthe SmartKey must be in the vehicle
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (Ypage 78).
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile phone
or another SmartKey
Rwith metallic objects, e.g. coins or metal foil
Rinside metallic objects, e.g. a metal case
This can impair the functionality of the KEY-
LESS-GO key.
Do not keep the KEYLESS-GO key in the tem-
perature-controlled cup holder (
Ypage 309).
Otherwise, the KEYLESS-GO key will not be rec-
ognized.
If you lock the vehicle with the SmartKey remote
control or with KEYLESS-GO, after a short time:
Ryou will not be able to switch on the ignition
with the Start/Stop button
Ryou 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 button
on the front door (
Ypage 83), you can continue
to start the engine with the Start/Stop button.
The engine can be switched off while the vehicle
is in motion by pressing and holding the Start/
Stop button for three seconds. This function
operates independently of the ECO start/stop
automatic engine switch-off function.

The required distance between remote con-
trol Aand the integrated garage door opener
depends on the garage door drive system.
Several attempts might be necessary. 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"
(Ypage 321).
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 programming button
may be located in different places depending on
the manufact

urer. 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 "Program-
ming additional remote controls", before carry-
ing out the following steps.
Your vehicle must be within reach of the garage
door or gate opener drive. Make sure that nei-
ther your vehicle nor any persons/objects are
present within the sweep of the door or gate.

Problems when programming
If you are experiencing problems programming
t
he integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
RCheck the transmitter frequency used by
garage door drive remote control Aand
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remote control Afor the garage door drive.
The integrated garage door opener is com-
patible with devices that have units which operate in the frequency range of 280 to
433 MHz.
RReplace the batteries in garage door remote
control
A. This increases the likelihood that
garage door remote control Awill transmit a
strong and precise signal to the integrated
garage door opener.
RWhen programming, hold remote control A
at varying distances and angles from but-
tons ;to? which you are programming. Try
various angles at a distance between 2and
8 inches (5to 20 cm) or at the same angle but
at varying distances.
RIf a further remote control Ais available for
the same garage door drive, repeat the same
programming steps with this remote control
A. Before performing these steps, make sure
that new batteries have been installed in
garage door drive remote control A.
RNote that some remote controls only transmit
for a limited amount of time (the indicator
lamp on the remote control goes out). Press
buttonBon remote control Aagain before
transmission ends.
RAlign 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.
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 140).
XPress button ;,=or? which you pro-
grammed to operate the garage door.
