A system for controlling a motor vehicle comprising a first set of vehicular functions (V-CAP) which are potentially possible to execute in the vehicle, where the vehicle includes: a user interface configured to receive personal data (D-ID) designating an identity of a user of the vehicle, and a communication device configured to, in response to received personal data (D-ID), transfer said personal data (D-ID) and in association there with transfer vehicular data (V-ID) designating the identity of the vehicle to a central data processing unit, and receive activation messages (MSG-A) from the central data processing unit and in response to a received activation message (MSG-A) adapt at least one setting of the vehicle, characterized in that the central data processing unit is configured to: receive said personal data (D-ID) and said vehicular data (V-ID) associated there with, and in response thereto investigate whether the user whose identity is designated by said personal data (D-ID) is an authorized user of the vehicle; and given that this is the case, match a description (D-CERT) of a set of vehicular functions for which the user is authorized with the first set of vehicular functions (V-CAP), wherein the central data processing unit is connected to a central storage unit which for each user in a group of users stores a respective description (D-CERT) of the set of vehicular functions for which the user in question is authorized, and wherein the description (D-CERT) of the set of vehicular functions for which the user is authorized is adapted as the user is educated on such vehicular functions, generate an activation message (MSG-A) designated to upon reception in the vehicle cause activation exclusively of those functions for which the user is authorized and which are included in the first set of vehicular functions (V-CAP), and transfer the activation message (MSG-A) to the vehicle. a user interface configured to receive personal data (D-ID) designating an identity of a user of the vehicle, and a communication device configured to, in response to received personal data (D-ID), transfer said personal data (D-ID) and in association there with transfer vehicular data (V-ID) designating the identity of the vehicle to a central data processing unit, and receive activation messages (MSG-A) from the central data processing unit and in response to a received activation message (MSG-A) adapt at least one setting of the vehicle, characterized in that receive said personal data (D-ID) and said vehicular data (V-ID) associated there with, and in response thereto investigate whether the user whose identity is designated by said personal data (D-ID) is an authorized user of the vehicle; and given that this is the case, match a description (D-CERT) of a set of vehicular functions for which the user is authorized with the first set of vehicular functions (V-CAP), wherein the central data processing unit is connected to a central storage unit which for each user in a group of users stores a respective description (D-CERT) of the set of vehicular functions for which the user in question is authorized, and wherein the description (D-CERT) of the set of vehicular functions for which the user is authorized is adapted as the user is educated on such vehicular functions, generate an activation message (MSG-A) designated to upon reception in the vehicle cause activation exclusively of those functions for which the user is authorized and which are included in the first set of vehicular functions (V-CAP), and transfer the activation message (MSG-A) to the vehicle.
