Don't be puzzled be grateful!

Lots of consumer items like cars are built to a standard, then upgraded or downgraded to meet particular marketing targets.

A redundant feature can sometimes be made to work, like cruise control, you have to search the web and add the missing bits. You may need to do no more than enable that missing item.

You would need an appropriate electronic interface to do this.

You certainly don't need a trip computer as our 2002 Corsa with no such computer has a push button to reset trip meter. You do need to hold push stalk on dash in for more than a second or two to get it to zero. Even the most basic of Corsas should be able to reset the trip meter.
