1.15.5. On-board computer


The Opel on-board computer informs on driving parameters which it periodically registers and analyzes in the electronic way.

By pressing buttons on the display the following functional fields, a row from them in a short form are highlighted:

  – Momentanverbrauch (fuel consumption at present);
  – Durchschnittsverbrauch (average fuel consumption);
  – Durchschnittsgeschwindigkeit (average speed of the movement);
  – Reichweite (a settlement run before refueling);
  – Stoppuhr (stop watch);
  – Aussentemperatur (external temperature).

Management by means of two buttons on the screen wiper lever

The button "S" – the choice (to press, the necessary field will not appear yet).
The button "R" – deleting (at emergence of functional fields):

  – average fuel consumption;
  – average speed of the movement by means of pressing of the button "R" (not less than 2 sec.) occurs their simultaneous indication.

The data which are written down before in memory will be automatically are erased and at the same time there will be a dumping of a stop watch.

Nonerasable data:

The current fuel consumption, settlement run before refueling and external temperature.

At the switched-on receiver later 5 sec. after involvement of the computer (key "S") in the top line of the display indication of the receiver appears again.

If the radio receiver is switched off, then in both lines of the display functions of the on-board computer will be presented.

Messages of control checks anyway have a priority.

Inclusion of the field of the computer is registered emergence below at the left on the display of the inscription "TRIP".

Malfunction indication

The message of "F" confirms malfunction. The field containing malfunction is blocked. To address in the authorized workshop Opel.

Fuel consumption at present


Indication changes depending on speed:

Indication in l/h is lower than 13 km/h (Indication in гал / is lower than 8 miles/h h)
Indication in l / 100 km over 13 km/h (Indication in m / гал over 8 miles/h)
Indication of 0 l / 100 km at draft switching off (Indyk. 999.9 m / гал at draft switching off)

Average fuel consumption

Calculation of average fuel consumption can be begun at any time, for example, after gas station. Dumping is made by pressing of the key "R".

Indication in l / 100 km (Indication in miles/gallon)

Average speed

Calculation of average speed can be begun again at any time, for example, after a start of motion. Dumping is made by pressing of the button "R".

Breaks in the movement with switching off of ignition when calculating are not considered.

Indications in km/h (indication in miles/hour)

The size of a residual run is over 50 km

The size of a residual run pays, proceeding from the current fullness of a tank and average consumption of fuel for the last 20–30 km of a way.

After gas station the new size of a residual run can be calculated by pressing of the key "R", or this size is automatically recalculated through прибл. 10 km.

Indication in km (Indication in miles)

The size of a residual run is less than 50 km

Indication appears without call the button "S" of the "Settlement Residual Run before Refuelling" function if in the fuel tank of fuel remained less than on 50 km of a way. The indicator at the same time blinks.

By a call of other functional field this precautionary function is turned off. Repeated automatic switching to "A settlement residual run before refueling" happens after the termination of the movement.

Indication in km (Indication in miles)

Stop watch

By pressing the button "R" zero – start – stop zero...

Commissioning of a stop watch does not influence functional fields:

  – average consumption of fuel;
  – average speed.

External temperature

At temperature drop индикацив reacts immediately, at rise – with a delay.


at a temperature of several degrees above 0 of °C (32 °F) the road can already be ice-covered.

At a temperature below 3 °C indication independently switches to "the external temperature". By a call of other functional field this precautionary function is turned off.

Indication in °C (Indication in °F)
