GF54.30-P-0002-05Q Instrument Cluster (IC), Operating Information
- up to 31.5.05

Component Identification:

As of 1.6.03 the display of the selected driving program in the gear indicator (A1p12) has changed from W, S to C, S (C = Comfort, S = Sport).

This document covers the following points:
^ Operating the multifunction display (A1p13)
^ Call display of different systems
^ Browse within a system
^ Individual settings
^ Change setting, e.g. change over temperature display from degrees Celsius (°C) to degrees Fahrenheit (°F)
^ Recall the factory settings
^ Call stored fault and warning messages
^ Acknowledge fault and warning messages in the multifunction display (A1p13)
^ Set brightness of lighting

Operating the multifunction display (A1p13)
If the instrument cluster (A1) is activated by opening the driver door, for instance, the main screen of the base system (trip and total mileage, outside temperature) always appears on the multifunction display (A1p13)

Calling up display of different systems
Function requirement is "Circuit 15R ON".
If the system selection button (S110s3) of the multifunction steering wheel is pressed, the multifunction display (A1p13) switches over to the basic display of the next system. Once the driver has scrolled through all systems the main screen of the base function appears again.

Function of scroll forward/back pushbutton (S110s1) using the base function as an example

The illustration above shows the possible systems arranged in a circle. When the system selection button (S110s3) is pressed, the display always goes to the next system.

You can jump to another system from any screen by pressing the system selection button (S110s3). With the exception of the trip computer, the basic display of this system then appears. If a change is made from the system in front to the trip computer system, the display screen is always called up which was last shown for the trip computer.

Scrolling within a system
Function requirement is "Circuit 15R ON".
In addition to the main screen, most systems also feature other screens.
The scroll forward/back button (S110s1) is used to scroll within a system.
The display jumps one screen further each time the driver presses the scroll forward/back pushbutton (S110s1). The display scrolls either forwards or backwards depending on which portion of the scroll forward/back pushbutton (S110s1) the driver presses.

As of 1.6.03 the base function is expanded by the system with the code (477) tire pressure loss warning.

Only systems and functions with which the vehicle is equipped are displayed. If a system is not present, it is not displayed (go toped) when the system selection button (S110s3) is pressed.

Recalling the factory settings
All the settings are erased and the manufacturer default settings are reproduced by the reset described in the following:
- Press the system selection button (S110s3) until the "SETTINGS" function appears in the multifunction display (A1p13).
- Operate the instrument lighting dimmer and reset button (A1r1) for at least 3 seconds.
- "RESET SETTINGS, CONFIRMATION WITH RESET BUTTON" appears in the multifunction display (A1p13)
- Operate the instrument lighting dimmer and reset button (A1r1) once more within 5 seconds, all the settings are now reset to the factory setting.
- "RESET TO MANUFACTURER DEFAULT SETTINGS" appears in the multifunction display (A1p13)

If the instrument lighting dimmer and reset button (A1r1) is not operated within this period of 5 seconds, the display switches back to the basic display. The settings are not then reset.

If a reset is performed while driving, the setting menu "Driving lights on" in the "Lights" menu and the setting menu "Speed limit (winter tires) in the "Vehicle" menu are not reset for safety reasons.
The message "NOT ALL SETTINGS RESET TO DEFAULTS WHILE DRIVING" appears.

Calling stored fault and warning messages
When the instrument cluster (A1) is active, you can scroll though the saved messages:
^ Press the system selection button (S110s3) until the "PROBLEMS" display appears in the multifunction display (A1p13).
^ Using the button + and -, setting of specific functions and volume control (S111s1) scroll through the fault messages. The messages are displayed in the order in which they were acknowledged.

Confirm malfunction and warning messages
These messages are divided into 3 categories according to their priority.
Messages in categories 2 and 3 in the multifunction display (A1p13) can be acknowledged by pressing the instrument illumination rheostat and reset button (A1r1) as well as with the system selection button (S110s3) of the multifunction steering wheel and then stored in the fault memory.

Messages of category 1 (highest priority) cannot be acknowledged. Indicator or warning lamps that light up at the same time cannot be acknowledged.

Certain fault and warning messages are also accompanied by a chime. A fault message and warning message is "Close trunk lid" for example. Such fault messages and warning messages are not stored in the fault memory.

Setting illumination brightness
The brightness of illumination of the instrument cluster (A1) and the switch and controls illumination can be adapted to individual requirements with the dimmer for instrument, switch and controls illumination (A1r1):
^ Brightness is increased by turning to the right.
^ Brightness is reduced by turning to the left.

Workshop level of instrument cluster (A1)
Basic prerequisite is "Circuit 15R ON".
The following steps are necessary in order to reach the workshop level in the multifunction display (A1p13):
^ Adjust standard display (basic condition with current total mileage and trip odometer and outside temperature)
^ Press the instrument illumination rheostat and reset button (A1r1) for approx. 20 to 30 seconds, as of 1.6.03 3 times within approx. 2.5 seconds until a beep is audible

Via the scroll forward/back button (S110s1) on the multifunction steering wheel MFL it is possible to change between the individual sub-items:
^ On-board electrical system voltage display, as of 1.6.03
^ Chassis number, as of 1.6.03
^ Instrument cluster data
^ Dynamometer test mode

Switch on dynamometer test mode
With the dynamometer test mode the wheel speeds of the driven axle are reflected in the non-driven axle. This is necessary on the brake test stand so that no fault is entered in the ESP and BAS control unit (N47-5).
With the dynamometer test mode the wheel speeds of the driven axle are reflected in the non-driven axle.
^ Adjust workshop level in the multifunction display (A1p13)
^ Press scroll forward/back button (S110s1) once towards, until the "Dynamometer test" display appears
^ Switch on the roller test mode using the + and - button, adjustment of specific functions and volume control (S111s1).

The dynamometer test mode remains active, even if "Circuit 15R ON" has been switched off in the meantime, until it is switched off with the button + and -, setting of specific functions and volume control (S111s1).
