dow. Please avoid the areas shown in the following:
1. DO NOT use where it will block the driver's view.
2. DO NOT use where the air bags could deploy.
3. DO NOT use where it becomes a driving obstacle.
• The Global Positioning System (GPS) is built and operated
by the U.S. Department of Defence. The Department is re-
sponsible for accuracy and maintenance of the system. Any
changes by the Department may affect the accuracy and
function of the GPS system.
• When the GPS receiver is activated, please do not cover
the ID-31A or ID-31E with anything that will block the satel-
lite signals.
• The GPS receiver may not work if used in the following loca-
tions:
