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