BMW 3 SERIES 2018 Repair Manual

General
information
There are three driver profiles with which perj
sonal vehicle settings can be stored. Every rej
mote control has one of these driver profiles
assigned.
If the vehicle is unlocked using a remote conj
trol, the assigned personal driver profile will be
activated. All settings stored in the driver proj
file are automatically applied.
If several drivers use their own remote control,
the vehicle will adjust the personal settings
during unlocking. These settings are also rej
stored, if the vehicle has been used in the
meantime by a person with a different remote control.
Changes to the settings are automatically
stored in the driver profile currently activated.
If another driver profile is selected via iDrive, the settings stored in it will be applied autoj
matically. The new driver 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 driver profiles.
Functional
requirements

profile associated to a particular driver, the dej

remote control.'yThe driver unlocks the vehicle.'yThe driver gets into the vehicle through the
driver's door.
