Cruise control only works up to 110 km/h

I have a 2010 Toyota Estima Hybrid, that was imported from Japan into UK. One thing that bothers me slightly is that the cruise control seems to have a top speed limit of about 110 km/h. The dash has been converted to UK standards (i.e. miles) – so the max I can set the cruise control to is about 68-69 mph. If the car is moving faster than that (say, 70 mph), the cruise control simply doesn’t engage. If I engage it at 65-67 mph then attempt to increase the speed, it’ll increase to about 68-69 max (this is the equivalent of about 110 km/h).

While this isn’t a big issue in UK (I’m ok doing 69 instead of 70), this meant that the cruise control was pretty much useless in France where the motorway speed limit is 130 km/h. I really didn’t feel like going 20 km/h below the speed limit.

The car does happily go 130 km/h – but the cruise control just won’t engage at that speed.

Does anyone know how this limit is implemented? Is is possible to deactivate/change it?
