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. Some cellular services may interfere with SXM reception causing loss of signal.
Mobile Device Usage
Mobile device usage, such as making or receiving calls, charging, or just having the mobile device on may cause static interference in the radio. Unplug the mobile device or turn it off if this happens.
Multi-Band Antenna
The roof antenna is for AM, FM, SiriusXM, OnStar, and GPS (Global Positioning System), if equipped. Keep clear of obstructions for clear reception. If the vehicle has a sunroof, and it is open, reception can also be affected.
If equipped with an anti-theft alarm system, the indicator light, on the instrument panel near the windshield, shows the status of the system.
Off : Alarm system is disarmed.
On Solid : Vehicle is secured during the delay to arm the system.
Fast Flast : Vehicle is unsecured. A door, the liftgate, or the hood is open.
