VTG - Transfer case
As is already familiar from the G12, the G30 does not have Integrated Chassis Management (ICM). The ICM functions are distributed between the optional equipment system (SAS) and the Dynamic Stability Control (DSC).
It has been possible to further improve the driving dynamics in the G30 by selective use of various control functions. This is particularly keenly felt in relation to the steering behavior, the traction and the vehicle's stability.
The control units necessary to meet the requirements on driving dynamics are located on the FlexRay bus. This allows them to quickly exchange their information with each other and react to events.
The following actuators are activated as needed:
- Rear axle slip angle control HSR (optional equipment)
- Electronic Power Steering EPS (standard equipment)
- DME engine control unit
- VTG transfer case (optional equipment)
- Electric active roll stabilization at the front and rear (EARSV/EARSH) (optional equipment)
- Electronic Damper Control (EDC) (optional equipment)
The tables below provide an overview of the various control functions and their effects on the drivability.

Steering
The G30 has Electronic Power Steering (EPS) in the following different
versions:
Standard steering 12 V
Integral Active Steering 12 V

Stored trips
General information
Up to 30 trips can be stored in the trip list. If necessary,
delete existing trips to be able to store
new trips.
Storing
The destination guidance for the tip must be active.

Coolant pump
The layout and function of the coolant pump have been revised and adapted to
match the cooling
concept of the Bx8 TU engines.
