My Daihatsu Mira does not have any manual, Its an automatic car with TurboEngine and Gear with PRNDSB. What does all these means? My car is four wheel drive as I can see rear differential in it. If its a four wheel on which position of Gear I can activate the four wheel.
The letters are standard:
None of these have anything to do with 4WD or 2WD selection. If your Daihatsu is the 4WD version, it is permanently 4WD - there is no selector on that spec of car. It was a specific Japanese edition.
You have stated previously that you thought your car was a 2WD spec. I would read the online specs to find out exactly which model you have.
