Oil Change Reminder Lamp: Description and Operation

Information And Message Center

The message center display is a green (Expedition) or white (Navigator), fixed format, 2-line display integrated into the center of the Instrument Cluster (IC) and is controlled by the message center switches. There are 2 basic IC message center configurations. The first is the full-function message center and can be identified by the 3 button message center switch located in the instrument panel center finish panel. The second is the base IC message center and can be identified by the single reset button located in the IC. Both IC configurations display messages based upon vehicle option content.

The base IC message center functions and menus listed below can be selected through the reset button by pressing and releasing the reset button to scroll through the menu items. The INFO items (trip A, trip B and average fuel economy) can be reset by holding the reset button for approximately 2 seconds. The SETUP items, (language, system configurable items [autolamps, autolock, auto unlock, etc.]) can be reset by holding the reset button for approximately 2 seconds when the selected menu item is displayed. Refer to the Owner's Literature for complete operating instructions for both the full-function message center and the base IC message center. For additional information on the oil life start value and oil life reset procedures, refer to Message Center Configuration Reset Procedure.

The message center provides the following features:

- Information displays
- Setup displays
- System check messages
- System warning messages

The full-function message center features and menus listed below can be selected through a set of 3 buttons:

- INFO
- SETUP
- RESET

Message Center Configuration

The message center has the capability to configure items such as oil life, oil life start value, language, units (English or metric), autolamp delay, to enable/disable a variety of options such as easy entry/easy exit (if equipped) and air suspension (if equipped), or to carry out calibrations/settings on items such as the compass. On configurable items such as parking aid on/off and air suspension on/off (if equipped), the message center indicates the appropriate selection (ON/OFF) by bracketing the selection. An example is as follows: PARKING AID< ON> OFF. The parking aid is enabled or on in the previous example. If the driver selects the parking aid off, the display would be: PARKING AID ON< OFF>.

Oil Life and Oil Life Start Value

The oil life is displayed in percentages and is preset to a maximum of approximately 12,070 km (7,500 miles) or 180 days. The oil life start value is used to increase or decrease the starting point of the oil life. The value can be changed back to the maximum of approximately 12,070 km (7,500 miles) if the value was previously changed or to lower the value by 10% increments down to 10%. Each 10% reduction lowers the oil life in both mileage and the days.

For example, if the oil life start value is lowered to 50%, the maximum mileage is 6,035 km (3,750 miles) or 90 days. The oil life remains at the selected setting (50% in this example) until the driver changes the oil life start value. When the oil life (not oil life start value) is reset back to 100% following an oil change, the oil life resets to 6,035 km (3,750 miles). For configuration of the oil life and oil life start value, refer to Message Center Configuration Reset Procedure.

Message Center Indicators

The message center displays message center indicators in the RH side of the display area. Message center indicators replace indicators that have been typically displayed in the IC and use the same iconic representation.

Compass and Outside Air Temperature Displays

The message center provides a compass display and uses directional information sent from a compass module that is internal to the interior rear view mirror.

The message center provides an outside air temperature display on vehicles that are not equipped with Electronic Automatic Temperature Control (EATC).

System Check

The system check provides a check of all the monitored systems on the vehicle.

The message center displays OK for approximately 2 seconds if the system check does not detect a fault in the system and displays a warning message for approximately 2 seconds if the system check detects a fault in the system. Press the RESET button to scroll through the system check messages.

The systems monitored during the system check are:

System Warning Messages

The system warning messages alert the operator to possible problems or malfunctions in the vehicle operating systems. The message center displays the last selected feature if there are no additional warning messages. Once a warning message has been displayed, the message must be acknowledged to allow full-functionality of the message center. Press the RESET button to acknowledge and clear the warning message. The warning messages are divided into 4 categories:
