Radio Reception

Unplug electronic devices from the accessory power outlets if there is interference or static in the radio.

Radio Reception Tips


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.


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.

Sirius XM Satellite Radio Service

If equipped, Sirius XM 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, travelling or standing under heavy foliage, bridges, garages, or tunnels may cause loss of the Sirius XM signal for some time. Some cellular services may interfere with SXM reception causing a loss of signal.

Mobile Device Usage

Smartphone Integration

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 multi-band roof antenna may be used for radio, navigation, and other communication systems, depending on the equipped options. To ensure clear reception, keep the antenna clear of obstructions, such as snow and ice. If the vehicle has a sunroof, and it is open, or a roof loaded with cargo, reception may be affected.
