User settings and on-board computer (Discovery 3)

User settings

User settings allow the driver to adjust certain vehicle settings to change the functionality of selected vehicle features. User settings are only available on models with upgraded instrument clusters.

The settings are stored in the EEPROM of the instrument cluster. Each vehicle has a factory vehicle configuration file, which defines the settings for a number of functions. Factory settings cannot be deleted, so the dealer or driver can restore them at any time.

NOTE: Factory settings may vary depending on the market where this vehicle is sold.

The user settings are controlled by CAN bus input and output messages from the instrument cluster, central junction box (CJB), ABS module, and integrated audio head unit (IHU). The following table lists the modules and the functions they perform.

Functional purpose of user settings

To enter the user settings menu, press and release the trip computer button located at the end of the left multifunction switch. For safety reasons, the settings menu is only displayed when the vehicle is stopped. (the vehicle speed does not exceed 3 km/h), so that the driver is not distracted by working with the system. At speeds over 3 km/h, the settings window is not displayed on the display.

Once you enter the settings menu, you can move from one item to another using the audio control switches located on the steering wheel. To move from one menu item to another, use the search up and search down buttons (|<>|). The required values are set in the current menu using the volume control switches (+/-).

After entering the menu, the message "SETTINGS" appears on the message center display.

Now the driver can start working with the settings menu or exit it.

The user can go to the first menu item by pressing the button >>|, or to the last option by pressing the button |<<. After setting the required value, the setting is saved either when moving to the next menu item or when exiting the settings menu. The user settings menu can be closed at any time by pressing the on-board computer button.

If a menu item parameter has been changed, it is automatically saved when the next menu item is selected or when exiting the user settings menu.

Sound warnings

The instrument cluster can emit audible signals to notify the driver of a message being displayed on the display or of a change in the vehicle's operating conditions. Audible warnings are emitted by a buzzer built into the instrument cluster. Audible warnings are divided into three groups: 1) audible signals accompanying the display of warning messages or the switching on of indicator lamps; 2) sound signals of the vehicle systems status; 3) sound signals of the state of the indicator lamps. The following are cases when warning sound signals are given at the request of various vehicle subsystems:

• Warning about lights not turned off
• Warning about unfastened seat belts
• Warning of the operation of the direction indicator/hazard warning lights
• Speed Warning
• Seat Position Memory Warning
• Parking Assist Front Sensor Warning
• Anti-theft system warning
• Key in ignition warning

• Hill Descent Control System On Warning
• Warning about the message of the automatic stability control system on descent
• Additional security system warning
• Engine Management System Warning
• Low engine oil pressure
• Exceeding the maximum speed of the on-board computer

Audible warnings may be given in the form of a single, double or repeating beep. Audible warnings may be initiated by a CAN bus message from the control modules of the requesting subsystems or by the instrument cluster software.

On-board computer

The upgraded instrument clusters have software that enables the use of an on-board computer. The on-board computer provides the driver with information about current fuel consumption, the duration of the current trip, the average speed, and the distance that can be traveled with the available amount of fuel. The information is displayed at the bottom of the message center display, provided that there are no messages with a higher display priority. If there are no other messages or if they have a low priority, the message center display shows the on-board computer information.

Item name	Spare part catalog number	Description
1	-	On-board computer button

Access to the on-board computer and changing some parameters responsible for displaying information on the display is carried out using the on-board computer button located at the end of the left multi-function switch.

Functional capabilities of the on-board computer

When the engine is started, the instrument cluster goes into diagnostic mode and a message appears on the message center display. "System check in progress" (system check in progress). Once the diagnostics are complete, the instrument cluster displays warning messages in order of priority, such as:, "DRIVER'S DOOR OPEN" (the driver's door is open).



After displaying warnings, the message center display changes to mode 3E. When the vehicle is stopped, pressing the trip computer button once displays the user settings menu on the display. Pressing the button again exits the settings menu and displays trip information. If the vehicle is moving, the settings menu call is ignored and trip computer information is displayed in the following order:
