New Features
The fuel tank contents, current consumption, total mileage and trip odometer, which have until now been displayed in separate, fixed-position displays in the instrument cluster, are now integral parts of the On-Board Computer.
They are scrolled through as items of information and only displayed when the driver actively requests them.
Only the fuel gauge is automatically displayed as soon as the reserve level is reached. Most of the data for the On-Board Computer is transferred by control units in digital form via the K-CAN System to the instrument cluster, where it is processed and displayed in the instrument cluster itself or in the Control Display (transfer to that point by MOST telegram).
Coolant level, wiper fluid levels and the outside temperature are signaled to the instrument cluster by hardwire.
The tank level is reported in redundant form by two independent analog direct lines to the instrument cluster.
In the case of average values, only dashes are displayed until the wheel speed signal arrives. The wheel speed signals are reported by the sensor of the left-hand rear wheel via the DSC control unit per K-CAN System to the instrument cluster. If this sensor is defective, the right-hand rear wheel is used.
All texts for the On-Board Computer are stored in the Control Display. The corresponding numerical values are provided by the instrument cluster via MOST. The information memory for consumption and travel distances is also located in the instrument cluster.
The On-Board Computer in the Control Display is operated by means of the Controller on the center armrest.
It consists of the following sub-functions:
- "Main" on-board computer , referred to simply as the On-Board Computer. Its information can be called up and scrolled as in previous models by pressing the turn signal switch and viewing the display in the instrument cluster.
- Travel Computer. This computer is used to monitor one or more parts of a trip; its information can only be displayed in the Control Display.
- Stopwatch and limit. These can also, like the travel computer can only be displayed in the Control Display, but they can be activated directly in the main menu "On-board computer".
- Setting menu for independent ventilation, clock/date and memory signal are activated using the entry "Settings" in the main menu "On-board computer". The "units" selection for the entire scope of the on-board computer are also located here.
Not all functions of the On-Board Computer that are displayed in the Control Display can also be displayed in the instrument cluster; only those of the "main" On-Board Computer can do this.
However, the functions of the On-Board Computer that cannot be displayed in the Control Display can only be displayed in the instrument cluster (fuel gauge, total mileage, trip distance).
