1.10.24. On-board computer

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

By pressing the button on the display are highlighted:

  – instant fuel consumption;
  – average fuel consumption;
  – average speed;
  – course stock;
  – stop watch;
  – external air temperature;
  – time and time in way (continuous indication).


At the switched-off ignition – time; at the included ignition – time, by consecutive pressing of the step button – the chosen field of parameters.

""on the display confirms malfunction: for elimination of the reason address in the workshop Opel.

Step button (forward)

Press before emergence of indication of the desirable field of parameters.

Starting button (back)

At indication of fields of the parameters "average fuel consumption", "average speed" by pressing the starting button (at least 2 sec.) both fields are started at the same time.

The data which are written down before in memory will be automatically erased – at the same time there will be an installation of a stop watch on zero.

Nonerasable data: time, current fuel consumption, stock of the course and external temperature.

Installation of time

To press – indication of hours blinks,
to press – indications of hours are established,
to press – indication of minutes blinks,
to press – indications of minutes are established,
to press – start of a stop watch.

Short-term pressing – slow change of indications.
Pressing and long deduction – bystry change of indications.

Current fuel consumption

Indication changes depending on speed:

 – indication in l/h – is lower than 10 km/h (indication in гал / h – lower than 6,2 miles/h);
 – indication in l / 100 km – over 10 km/h (indication in m / гал – over 6,2 miles/h).

Average fuel consumption

Calculation of average fuel consumption it is possible at any time, for example, after gas station – start over again pressing of a key O. Indication in l / 100 km (indication in m / гал).

Average speed

Calculation of average speed can be begun again at any time – for example, after a start of motion – pressing of the button O.

Breaks in the movement with switching off of ignition when calculating are not considered. Indication in km/h (indication in miles/h).

Course stock over 50 km

The stock of the course 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 stock of the course can be calculated by pressing a key, or this size is automatically recalculated through approximately each 10 km. Indication in km (indication in miles).

Course stock less than 50 km

Indication appears without function call if the maintenance of a tank is enough for distance less than 50 km. Indication blinks.

By a call of other functional field this precautionary function is turned off. New automatic switching on "A course stock less than 50 km" happens after a stop of the movement. Indication in km (indication in miles).

Stop watch

Commissioning of a stop watch does not influence functional fields:

  – average consumption of fuel;
  – average speed.

By pressing the button zero - start - stop zero...

Measurement time
... the shown figures mean
up to 10 min.

from above 100th hour

External air temperature

Current indication. At temperature drop indication reacts immediately, at increase – with a delay.

Carefully: at indication several degrees above 0th °C (32 °F) the road can already be ice-covered.

At a temperature below 3 °C indication without involvement of the step button with a blinking switches to "the external temperature". By a call of other field of parameters this precautionary function is turned off. Indication in °C (indication in °F).
