Operation and display
In the F01/F02, Dynamic Cruise Control is no longer operated by means of an operating lever. Instead, the driver can operate the function conveniently using a button pad on the multifunction steering wheel.
| Index | Explanation |
|---|---|
| 1 | SET button to activate |
| 2 | Rocker switch to change the set speed |
| 3 | I/0 button to switch on and off |
| 4 | RES button to resume a stored set speed |
To prevent accidental activation, the function remains inoperable until the I/0 button has been pressed after the vehicle has started. This switches the function to standby. This state is acknowledged in the instrument cluster by a green indicator light lighting up.
With the function in standby, the driver is now able to activate cruise control. To do this, the driver can press the SET button used to store the vehicle's current road speed as the set speed. An active state is indicated by a green indicator light in the circumference of the speedometer dial lighting up.
There is an alternative way to activate the function if a set speed has already been stored. This is indicated by an orange indicator light in the circumference of the speedometer dial. If the driver wants to use this speed value as the set speed, he simply has to press the RES button. Dynamic Cruise Control then accelerates or decelerates the vehicle to this speed value automatically.
While the function is active, the driver is able to increase or decrease the set speed at any time. There are two adjustment increments available. The rocker switch offers two different increments in either direction. First, the set speed is altered in increments of 1 km/h each time the rocker switch is pressed; second, it is altered in increments of 10 km/h.
If the rocker switch is pressed and held, the system will accelerate/decelerate the vehicle until the rocker switch is released. This is known as a "comfort dynamics" function as featured in the E9x and E6x LCI.
To deactivate the system, the driver can simply operate the brake pedal like before. Or, the driver can deactivate the system by pressing the I/0 button. The system is then returned to standby and keeps the set speed last used stored in its memory.
If the driver then presses the I/0 button once more, the system is completely switched off and the green indicator light in the instrument cluster goes out.
There follows a summary of the most important displays for Dynamic Cruise Control.
| Index | Explanation |
|---|---|
| A | "Standby" state |
| B | "Active" state |
| 1 | Orange LED: set speed of 130 km/h (81 mph) stored |
| 2 | Indicator light for Dynamic Cruise Control |
| 3 | Green LED: actively maintaining a set speed of 130 km/h (81 mph) |
| 4 | Set speed displayed numerically: briefly displayed at the time of function activation or whenever the set speed is changed |
In the event of particular operating states, the displays shown here are supplemented by information messages displayed below the speedometer. This is the case, for instance, if the driver attempts to activate the system even though not all the activation criteria have been fulfilled (e. g. speed less than 18 mph).
In the F01/F02, a difference in the way Dynamic Stability Control interacts with Dynamic Cruise Control has been introduced. This is explained by the following example: Using the "Dynamic Performance Control", the driver has selected a mode in which DSC is inactive (e. g. "Sport+" mode). If the driver now activates cruise control, DSC will be activated automatically. This is accompanied by an automatic changeover from "Dynamic Performance Control" to "Normal" mode. In previous vehicles, the driver was unable to activate cruise control without activating DSC manually first.
