by model and require a complete working
electrical system, cell reception, and GPS
signal. An active connected plan is required.
Reference the SiriusXM user guide for use
and subscription information.
Radio Reception
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.
Fixed Mast Antenna
The fixed mast antenna will go through
most car washes as long as it is securely
attached. If the antenna becomes slightly
bent, straighten it out by hand. If it is badly
bent, replace it.
Occasionally check that the antenna is tight
at the base. If tightening is required, protect
the paint from damage.
Multi-Band Antenna
The roof antenna is for SiriusXM Satellite
Radio, OnStar, and GPS (Global Positioning
System), depending on the equipped
options. Keep clear of obstructions for clear
reception. If the vehicle has a sunroof, and it
is open, reception can also be affected.
Audio Players
Avoiding Untrusted Media Devices
When using media devices such as SD cards,
USB devices, and mobile devices, consider
the source. Untrusted media devices could
contain files that affect system operation or
performance. Avoid use if the content or
origin cannot be trusted.
USB Port
This vehicle is equipped with two USB ports
in the center console under the armrest and
another two in the center stack. These ports
are for data and charging.
There may also be two USB ports for
charging only at the rear of the center
console.

or other types of media display, a vertical
keyboard appears on one side of the list and
a scroll bar on the other side. When using
the vertical keyboard, touch the beginning

zoom bubble of that character. Release the
finger from the infotainment display and
the zoom bubble disappears.

and down.
File System and Naming

the song information is not available.Supported Apple Devices

infotainment display to resume playback.
Other phones such as Android phones may
have a similar reaction.
Bluetooth Streaming Audio and Voice
Recognition
See
Bluetooth Audio 0162 for information
using voice recognition with Bluetooth
streaming audio.
Make sure all devices have the latest
software downloaded.
Auxiliary Jack
If equipped, this vehicle may have an
auxiliary input jack. This may be located in
the center stack or center console under the
armrest. Possible auxiliary audio sources
include:
.Laptop computer
.Audio music player
This jack is not an audio output. Do not
plug headphones into the auxiliary input
jack. Set up an auxiliary device while the
vehicle is in P (Park).
Connect a 3.5 mm (1/8 in) cable from the
auxiliary device to the auxiliary input jack.
When a device is connected, the system can
play audio from the device over the vehicle
speakers.
If an auxiliary device has already been
connected, but a different source is currently
active, press MEDIA on the center stack or
touch the Media icon on the infotainment
display to scroll through audio source
menus, until the AUX Input source appears.
Playing from the AUX Port
An auxiliary device is played through the
audio system and controlled through the
device itself.
