vehicle is stationary cannot be used via the
voice activation system.▷The system uses a special microphone on
the driver's side.▷›...‹ Verbal instructions in the Owner's Man‐
ual to use with the voice activation system.
Requirements

the marked area on the steering column.2.Start the engine within 10 seconds.
If the remote control is not detected, slightly
change the position of the remote control and
repeat the procedure.
Personal Profile
The concept
Using Personal Profile, individual settings for
several drivers can be saved and called up
again at a later time.
General information There are three profiles with which personal ve‐
hicle settings can be stored. Every remote con‐
trol has one of these profiles assigned.
If the vehicle is unlocked using a remote con‐ trol, the assigned personal profile will be acti‐
vated. All settings stored in the profile are auto‐
matically applied.
If several drivers use their own remote control,
the vehicle will adjust the personal settings dur‐
ing unlocking. These settings are also restored,
if the vehicle has been used in the meantime
by a person with a different remote control.
Changes to the settings are automatically saved
in the profile currently activated.
If another profile is selected via the onboard
monitor, the settings saved in it will be applied
automatically. The new profile is assigned to
the remote control currently used.
There is an additional guest profile available
that is not assigned to any remote control: It can be used to apply settings in the vehicle
without changing the personal profiles.
Adjusting
The settings for the following systems and func‐
tions are saved in the active profile. The scope
of storable settings is country- and equipment-
dependable.▷Unlocking and locking.▷Lights.▷Radio.▷Instrument cluster.▷Programmable memory buttons.▷Volumes, tone.▷Control Display.▷Climate control.▷Navigation.▷Park Distance Control PDC.▷Rearview camera▷Head-up Display.▷Driving Dynamics Control.▷Intelligent Safety.
