Further Information
NOTE•Because the GPS satellite is in orbit around the earth, the reception status for
the electromagnetic waves changes depend ing on their position at that point
in time, even if your vehicle is in th e same place. Also, electromagnetic-waves
from satellites near the horizon can be easily influenced by surrounding
obstacles.
• At times, satellites under the control of the US Department of Defence will
intentionally drop positioning accuracy.
Regarding Errors in Current Position Display
The system displays the vehicle current position based on GPS
information and data from various sensors and road maps. However,
when the radiowave signals from GPS satellites are weak or when
signals are received only from two sate llites or less, errors may occur in
the position. Modifying or adjusting the system will not prevent these
errors.
