Infotainment System 127
To use the full SiriusXM 360L program,
including streaming content and listening
recommendations, OnStar Connected Access
is required. Connected vehicle services vary
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 powerlines 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 may be used for radio,
navigation, and OnStar, 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 USB and
mobile devices, consider the source.
Untrusted media devices could contain files
that affect system operation or performance
and should be avoided.
USB Port
Audio stored on a USB device may be
listened to.
Depending on your vehicle, it may be
equipped with two USB ports in the center
console under the armrest and another two
on the center stack. These ports are for data
and charging. There may also be two USB
ports at the rear of the center console and a
USB port on each side of the third row seats
for charging only.
Caution
To avoid vehicle damage, unplug all
accessories and disconnect all accessory
cables from the vehicle when not in use.
Accessory cables left plugged into the
vehicle, unconnected to a device, could be

starting the vehicle. An internal thermostat
in the plug end of the cord will prevent
engine coolant heater operation at
temperatures above−18 °C (0 °F).
To Use the Engine Heater 1. Turn off the engine.
2. Remove the heater cord from the rear compartment.
3. Check the heater cord for damage. If it is damaged, do not use it. See your dealer
for a replacement. Inspect the cord for
damage yearly.
4. Plug the cord into the receptacle in the front fascia.
5. Plug the other end of the cord into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord or an
extension cord can damage the cord and
may result in overheating and fire.
.Plug the cord into a three-prong
electrical utility receptacle that is
protected by a ground fault detection
function. An ungrounded outlet could

(Continued)
Warning (Continued)
.Use a weatherproof, heavy-duty,
15 amp-rated extension cord if needed.
Failure to use the recommended
extension cord in good operating
condition, or using a damaged heater
or extension cord, could make it
overheat and cause a fire, property
damage, electric shock, and injury.
.Do not operate the vehicle with the
heater cord permanently attached to
the vehicle. Possible heater cord and
thermostat damage could occur.

cord touch vehicle parts or sharp
edges. Never close the hood on the
heater cord.
.Before starting the vehicle, unplug the
cord, reattach the cover to the plug,
and securely fasten the cord. Keep the
cord away from any moving parts.
The length of time the heater should remain
plugged in depends on several factors. Ask a
dealer in the area where you will be parking
