Installing The Interface; Initializing The Interface; Adjusting The Interface - Metra 99-3018 Instrucciones De Instalación

Installing the interface

With the key in the off position
• Connect the 16-pin harness with stripped leads into the interface.
• Connect the 3018 harness into the interface, and then to the wiring harness in
the vehicle.

Initializing the interface

Attention! If the interface loses power for any reason, the following steps will need
to be performed again. Also, if installing an ASWC-1, connect it after you initialize and
test the interface/radio, with the key in the off position.
• Turn the key (or push to start button) to the ignition position and wait until the
radio comes on.
Note: If the radio does not come on within 60 seconds, turn the key to the
off position, disconnect the interface, check all connections, reconnect the
interface, and then try again.
• Turn the key (or push to start button) to the off position, and close all doors,
including the trunk and hood.
• Allow the dome light to go out to ensure no data communication is active.
• Start the vehicle and test all functions of the installation for proper operation,
before reassembling the dash.
Note: If the climate control does not function, turn the key to the off position,
disconnect the interface, check all climate control connections, reconnect the
interface, and then completely initialize the interface again.

Adjusting the interface

Audio level adjustment (digital amplified models only):
• With the vehicle and radio turned on, turn the volume up 3/4 of the way.
• With a small flat-blade screwdriver, adjust the potentiometer clockwise to raise
the audio level; counterclockwise to lower the audio level.
• Once at a desired level, audio level adjustment is complete.
Chime level adjustment (digital amplified models only)
• With the vehicle on, turn it off and leave the keys in ignition. Open the driver's
door; chimes will be heard.
• Wait 10 seconds, and then with a small screwdriver, turn the potentiometer
clockwise to raise the chime level; counterclockwise to lower the chime level.
• When the chime is at a desired level, remove the keys from the ignition.
This will lock the chime volume at its current level.
OnStar level adjustment
• Press the OnStar button to activate it.
• While OnStar is speaking, press the "Volume up" or "Volume down" buttons on
the steering wheel to raise or lower the OnStar level.
• If the vehicle does not come equipped with steering wheel controls, locate the
Black/Yellow wire on the 22-pin harness.
• While OnStar is speaking, tap the Black/Yellow wire to ground. Once the OnStar level
is set, it will stay at that level until the Black/Yellow wire is tapped to ground again.
