cause serious burns and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.

other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle

Introduction to satellite radio*
SIRIUS satellite radio provides 100 chan-
nels of digital-quality radio. That includes
music, sports, news, and entertainment,
free of commercials. SIRIUS satellite radio
uses a fleet of high-power satellites to
broadcast 24 hours per day, coast to
coast, in the contiguous U.S. and Canada.
This diverse, satellite-delivered program-
ming is available for a monthly subscrip-
tion fee.
For more information and service
availability, call the SIRIUS Service
Center (1-888-539-7474), or contact
www.sirius.com (USA) or

after three consecutive scans of the complete
frequency range, then the scan stops at the
channel with which it began and
NO WB FOUND
appears in the display.
