CAUTION! Metra recommends disconnecting the negative bat -
tery terminal before beginning any installation, unless the vehicle
manufacturer recommends against so. Please check with your local
Dealership for more information. All accessories, switches, climate
controls panels, and especially air bag indicator lights must be con-
nected before reconnecting the battery or cycling the ignition. Also,
do not remove the factory radio with the key in the on position, or the
vehicle running. It would be best to remove the key from the ignition
and then wait a few seconds before removing the factory radio.
