System Overview

The Electronic Display Unit (EDU) trip computer has a different number of functions depending on the car's level of equipment and in which model it has been installed. There are two basic designs; EDU 3M for cars with manual gearbox and EDU 3A for cars with automatic transmission.

The trip computer has a set of buttons under the clock/Saab Car Computor (SCC) and a display under the speedometer which gives information about:
- Average fuel consumption
- Current fuel consumption
- Range possible on the fuel remaining in the tank
- Outside temperature
- Battery voltage

This information is shown in the left-hand part of the display under the speedometer. The information is changed by repeatedly pressing the INFO button.

The following is shown in the right-hand part of the display:
- CHECK ENGINE
- CHECK RADIATOR LEVEL

These warnings are displayed automatically. When the ignition is switched on, all these warnings should light and the go out, one at a time, within 4 seconds.
