 Inappropriate route guidance
may occur in the following
cases:

guidance.

and the system announces 1 or
more of them.

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