Power Antenna
The antenna automatically rises when the
radio is turned on, and lowers when it is
turned off. It does not need to be removed
when leaving the vehicle.

Radio Reception
AM characteristics
AM signals bend around such things as
buildings or mountains and bounce off the
ionosphere. Therefore, they can reach
longer distances than FM signals. Because
of this, two stations may sometimes be
picked up on the same frequency at the
same time.
FM characteristics
An FM broadcast range is usually about
40—50 km (25—30 miles) from the
source. Because of extra coding needed to
break the sound into two channels, stereo
FM has even less range than monaural
(non-stereo) FM.
Antenna
•
To prevent damaging the antenna,
retract it before entering a car wash
facility or passing beneath a low
overhead clearance.
•
Make sure no one is near the
antenna before turning on the radio
to prevent injury or damage to the
antenna.
