Precautions/System Performance

In the following situations, your vehicle position may not be displayed correctly on the 
map. But, as you keep driving, your vehicle position will be automatically corrected 
utilizing map matching and GPS data.

Although you may encounter the following problems in route guide, there is nothing 
wrong with the system.

Route Guide

For certain intersection shapes, 
the upcoming turn or the name of 
the intersection may not be 
announced.

For certain intersection shapes, 
you may be prompted to turn right 
or left When you should actually 
stay on the same road.

Voice guidance for the planned 
route may continue even after you 
have deviated from that route 
such as having turned too early.

Some points where the road 
divides on highways or toll roads 
may not be displayed or 
announced.

The Intersection Zoom Map may 
not always agree with the actual 
shape of the intersection.

The announced distance to an 
upcoming turn may differ slightly 
from reality.
