CHR speed warning error

[geoffus]

Just recently I am getting the speed limit symbol flashing and alarm sounding saying am speeding when I counld be as much as 30mph below the speed limit but the symbol is showing the correct speed anybody else having this problem? and what can I do

What generally happens is the Road sign assist function has become confused by a Speed limit sign in KPH ( likely on the back of a Continental lorry ) and has switched itself to KPH the car can automatically switch back but it may take a while, you can make it switch back by going into the settings on the screen between speedo/power meter and setting the units to KPH then power the car off, then power on go back into settings changing the units back to MPH this should correct the incorrect speed issue. otherwise book it into Toyota as there may be a fault.
