Unplug electronic devices from the accessory power outlets if there is interference or static in the radio.
FM
FM signals only reach about 16 to 65 km (10 to 40 mi). Although the radio has a built-in electronic circuit that automatically works to reduce interference, some static can occur, especially around tall buildings or hills, causing the sound to fade in and out.
AM
The range for most AM stations is greater than for FM, especially at night. The longer range can cause station frequencies to interfere with each other. Static can also occur when things like storms and power lines interfere with radio reception. When this happens, try reducing the treble on the radio.
SiriusXM Satellite Radio Service
If equipped, SiriusXM Satellite Radio Service provides digital radio reception. Tall buildings or hills can interfere with satellite radio signals, causing the sound to fade in and out. In addition, traveling or standing under heavy foliage, bridges, garages, or tunnels may cause loss of the SiriusXM signal for a period of time.
Cell Phone Usage
Cell phone usage, such as making or receiving phone calls, charging, or just having the phone on may cause static interference in the radio. Unplug the phone or turn it off if this happens.
Multi-Band Antenna
The roof antenna is for SiriusXM Satellite Radio, OnStar, GPS (Global Positioning System), and AM-FM. Keep clear of obstructions for clear reception. If the vehicle has a sunroof, and it is open, reception can also be affected.
The exterior lamp control is on the instrument panel to the left of the steering column.
There are four positions:
: Turns the exterior lamps off and deactivates the AUTO mode. Turn again to reactivate the AUTO mode.
