iDriveVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
The concept
The iDrive combines the functions of many
switches. Thus, these functions can be oper‐
ated from a central location.
Using the iDrive during a trip
To avoid becoming distracted and pos‐
ing an unnecessary hazard to your vehicle's
occupants and to other traffic, never attempt
to use the controls or enter information unless
traffic and road conditions allow it.◀

the Control Display, e.g. due to intense so‐
lar radiation, the brightness may be re‐
duced down to complete deactivation.
Once the temperature is reduced, e.g.
through shadow or climate control system,
the normal functions are re-established.

A Check Control message is displayed if an at‐
tempt is made to reel on the ignition or start
the engine.
Starting the engine via emergency detection of the remote control

saved in the profile currently activated.▷Unlocking the car activates the profile that
is stored in the remote control.▷Your personal settings will be recognized
and activated even if the vehicle had been
operated with another remote control.
Adjusting

functions are saved in the active profile. The
scope of storable settings is country- and
equipment-dependable.
