Precautions/System Performance
Voice guidance has the following functions:
nIntersection guidance
l
The system voice announces the distance to an upcoming turn and the turning direction.
This guidance function is automatic. Therefore, you do not have to set it, and it cannot be
disabled.
l The system vocally announces the distance to an upcoming highway branching point or
junction.
Voice Guidance
l The navigation system is just a support system for the driver. The driver should
always pay attention to the traffic situation to safely make decisions. You may
be unable at times to arrive at your destination due to out-of-date information
on a map disc. You should be especially careful when selecting an urgent
destination such as a hospital or a police station.
l Your route may sometimes include roads that are not open to vehicles or are
closed due to traffic regulations. Please comply with the local traffic
regulations.
l Do not change the settings and destination locations while driving. Minimize
the time spent viewing the monitor screen and listening to the voice guidance
while driving. Operating the system will distract the driver from looking ahead
of the vehicle and may cause an accident. Always stop the vehicle in a safe
location and use the parking brake before operating the system.
When two intersections are close together, the
voice guidance may be late. When two roundabouts are close together, the
voice guidance for the second may be late.

GPS is a position detecting system utilizing the signals
from GPS satellites deployed by the U.S. Department of
Defense. The Mobile Navigation System uses input from
three or more satellites and calculates the vehicle position
based on the principle of triangulation.
The positioning accuracy of the system corresponds to the
error display of the GPS which is from about 30 to 200 meters.
l If you are using the system for the first time, or if you have not used it for some time, it takes
about 5 minutes (or about 2 minutes in open areas) to calculate your vehicle’s position.
nGPS signal reception is poor in the following places
lThe GPS satellites are controlled by the U.S. Defense Department, which may intentionally
lower positioning accuracy. In such cases, there may be vehicle position deviations.
l There may be vehicle position deviations for some time until GPS signals are received after
turning on the ignition.
This function compares your vehicle’s tracking data with the road data on the map
disc, applies dead reckoning to determine the road you are driving on, and displays
your vehicle on that road on the map.
l Intelligent map matching addresses the following problems to achieve high accuracy in
vehicle positioning.
Position Correction for Elevated RoadsPosition accuracy is improved by detecting if the vehicle is
running on or under an elevated road.
Position Correction for Parking GaragesPosition accuracy is improved by detecting if the vehicle is
driving in an elevated or underground parking garage.
High-precision GyrosensorA gyro detects turns with an accuracy of 0.05° per second.
Combined with a speed sensor, it enables the system to
display the current vehicle position even where GPS signals
may be blocked.
l Using a spare tire in place of the regular one may cause vehicle position deviations.
l Any difference between the direction which your vehicle actually travels and that shown on
the map is automatically eliminated by azimuth correction.

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