When battery power is removed and later applied, you
will not have to reset your home radio presets because
the radio remembers them. However, you will have to
reset your away radio presets.
Theft-Deterrent Feature
THEFTLOCK
R
is designed to discourage theft of your
radio. Your vehicle has a “built
-
in” theft
-
deterrent
feature on each radio that is automatic
--
there is no
programming required. The radio in your vehicle cannot
be used in any other vehicle. When the radio was
originally installed in your vehicle at the factory, it
stored the Vehicle Identification Number (VIN). Each
time the ignition is turned on, the VIN is verified. If the
vehicle’s VIN does not match the VIN stored in the
radio, THEFTLOCK will be activated and the audio
system will not play. If the radio is removed from your
vehicle, the original VIN in the radio can be used to
trace the radio back to your vehicle.
Audio Steering Wheel Controls
Some audio controls
can be adjusted at the
steering wheel. They
include the following:
VOL: Press the up arrow button to increase volume and
the down arrow button to decrease volume.
