INFORMATION
●
This navigation system uses tyre turning
data and is designed to work with factory-
specified tyres for the vehicle. Installing
tyres that are larger or smaller than the
originally equipped diameter may cause
inaccurate display of the current position.
The tyre pressure also affects the diame-
ter of the tyres, so make sure that the tyre
pressure of all 4 tyres is correct.
