• Your destination point might be
shown on the opposite side of the
street.
• When a portion of the route has regu-
lations prohibiting the entry of the

INFORMATION
This navigation system uses tyre turn-
ing 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 dis-
play of the current position. The tyre
pressure also affects the diameter of
the tyres, so make sure that the tyre
pressure of all 4 tyres is correct.
