You cannot position your vehicle on the map or the positioning error is large.

The quality of signals from the GPS satellites is poor, causing reduced positioning accuracy. Such a loss of signal quality may happen for the fol- lowing reasons:

•The GPS antenna is in an unsuit- able location.

•Obstacles are blocking signals from the satellites.

•The position of satellites relative to your vehicle is bad.

•Signals from the GPS satellites have been modified to reduce accuracy. (GPS satellites are oper- ated by the US Department of Defense, and the US government reserves the right to distort posi- tioning data for military reasons. This may lead to greater position- ing errors.)

•If a vehicle phone or cellular phone is used near the GPS antenna, GPS reception may be lost temporarily.

•Do not cover the GPS antenna with spray paint or vehicle wax, because this may block the reception of GPS signals. Snow buildup can also degrade the signals.

Check the GPS signal reception (➞ Page 93) and the position of the GPS antenna if necessary, or continue driving until reception improves. Keep the antenna clear.
