On the left hand instrument stalk there is a wheel which if you turn moves the TFT through various detail displays which appear to the lower left and right of the main dial:
- Average MPG + Average Speed
- Current MPG + Distance to empty tank
- Current MPG + Speed in km/h
That is the only way I know to view the km/h.
As the TFT is a soft display it really can't be that hard to allow a My Car setting switch to km/h - can it Volvo???
Other slightly annoying things about the TFT display:
1) Current MPG is duplicated - I guess Volvo couldn't think of anything else to put there.
2) Current MPG maxes out at 50 mpg - this has been raised elsewhere on the forum.(http://www.volvov40club.com/forums/Thread-TFT-Display-Instant-Fuel-Consumption)
Having said all that I still think the TFT is a seriously neat gadget
