Locking and unlocking
Important notes on using KEYLESS-GO*

You can also use the SmartKey with
KEYLESS-GO like a normal SmartKey
(
page 112).
The starter switch is located under the
KEYLESS-GO button. Pull the
KEYLESS-GO button out in order to ac-
cess the starter switch (
page 43).

You can combine KEYLESS-GO func-
tions with normal SmartKey functions
(e.g. unlocking with KEYLESS-GO and
locking with the ‹button).

Always carry the SmartKey with
KEYLESS-GO with you.

Never store the SmartKey with
KEYLESS-GO together with:

electronic items such as a cellular
phone or another SmartKey with
KEYLESS-GO

metallic objects such as coins or
metal foil
Doing so could impair the function of
the KEYLESS-GO system.

To lock or unlock the vehicle, the
SmartKey with KEYLESS-GO must be
located outside the vehicle within ap-
proximately 3 ft (1 m) of the respective
door or the tailgate.

If the vehicle has been parked for more
than 72 hours, you must pull an outside
door handle in order to activate the
KEYLESS-GO function.

In order to start the engine with the
SmartKey with KEYLESS-GO:

The SmartKey with KEYLESS-GO
must be located in the vehicle.

The KEYLESS-GO start/stop button
must be inserted in the starter
switch (
page 43).

The brake pedal must be firmly
depressed. Do not depress the
accelerator.

If the SmartKey with KEYLESS-GO is
positioned farther away from the vehi-
cle, the system may no longer recog-
nize the SmartKey with KEYLESS-GO.
The vehicle then cannot be locked or
the engine started via the KEYLESS-GO
system.

If you have started the engine with the
KEYLESS-GO start/stop button
(
page 57), you can turn it off again by

pressing the KEYLESS-GO
start/stop button (
page 69)

inserting the SmartKey into the
starter switch when the vehicle is at
a standstill and the automatic
transmission is in positionP

Control system
Multifunction steering wheel
The displays in the multifunction display
and the settings in the control system are
controlled by the buttons on the multifunc-
tion steering wheel.
Depending on the selected menu
(

multifunction steering wheel will alter what
is shown in the multifunction display.
The information available in the multifunc-
tion display is arranged in menus, each
containing a number of functions or sub-

within the relevant menu (radio or
CD operations under
AUDIO, for example).
These functions serve to call up relevant
information or to customize the settings
for your vehicle.
