| EBD | | Electronic Brakeforce Distribution |
|---|
 | EBD optimises the performance of the car's ABS anti-lock braking system. ABS prevents an individual wheel from locking by cutting brake pressure as soon as a skid is detected. EBD takes this approach into another dimension. It can, for instance, adjust the braking force between the front and rear wheels to suit the car's load and road conditions, or brake the wheels on one side slightly harder than the other to maintain stability during a corner. |

| EDC | | Electronic Damper Control |
|---|
 | Electronic Damper Control (EDC) combines supreme driving comfort with similarly outstanding safety on the road. At the same time, the system consistently guarantees optimum vibration control regardless of the load the car is carrying. All measurements are permanently monitored by sensors and then evaluated by a microprocessor and commands are sent to the dampers, where solenoid valves serve to infinitely adjust damper forces to changing road, load and driving conditions. Furthermore, at the touch of a button the driver can choose the Sports program, making the suspension and dampers much firmer and more dynamic. |

| EDL | | Electronic Differential Lock |
|---|
 | The Electronic Differential Lock (EDL) applies brake force with the utmost precision to a rotating drive wheel up to a certain speed and then transfers the torque to the other wheel. An additional hydraulic pump is responsible for this transferral: if a pre-determined torque value for the wheels is exceeded, the pressure is rerouted via a magnetic valve to a faster-turning wheel, thereby braking it. |

| EPB | | Electromechanical Parking Brake |
|---|
 | The Electromechanical Parking Brake is an automatic handbrake. This sophisticated brake system offers two further benefits: Autostop and Hillhold. Autostop ensures that the car is automatically braked and held at a standstill when required: this means that the driver no longer has to keep their foot on the brake, as is the case on a conventional automatic transmission in order to prevent the usual "idling creep". Hillhold prevents the car from rolling downhill when starting on a gradient. With the engine running, all park braking processes are controlled by hydraulics via the Dynamic Stability Control (DSC) pump. When the engine is switched off, the same functions are controlled electromechanically via conventional bowden cables connected to the dual servo parking brake on the rear axle. |
