Precautions on use
Accurate Operation Tips
iii
This navigation system uses the tire turning
data.
So, replacing the tire may cause a posi-
tioning error.
Make sure tire pressures of 4 wheels should be
correct.
For your safety, some functions may become
inoperable when you start driving.
Unavailable switches are dimmed.
CAUTION
D
For safety, the driver should not
operate the navigation system during
driving.
Incorrect maneuvering of
steering wheel may cause an accident.
D
When driving, be sure to follow traffic
regulations and keep the road
condition in mind.
If a traffic sign on
the road is changed by the regulation,
route guidance may provide wrong
information such as the route
prohibiting the entry of the vehicle.
This navigation system calculates the cur-
rent vehicle position using satellite signals,
various vehicle signals, map data, etc.
How-
ever, the accurate position may not be shown
or inappropriate route guidance may occur
in some cases.
(a)
The accurate current vehicle
position may not be shown in the
following cases:
D
When driving on a small angled Y–shaped
road.
D
When driving on a spiral road.
D
When driving on a slippery road such as in
sand, gravel, snow, etc.
D
When driving on a long straight road.
D
When the freeway and surface streets run in
parallel.

the GPS, the current vehicle position, if
it is not placed in correct position or on
the wrong road, will be corrected auto-
matically.
D
If your vehicle cannot receive GPS sig-
nals, you can correct it manually.
For
the information on current position cal-
ibration, see page 65.
