within the operating range and the
oil pressure is still low, have the
vehicle serviced. Always follow the
maintenance schedule for changing
engine oil.
This light should come on briefly as
the engine is started. If it does not
come on, have the vehicle serviced by

.Display messages from radio
stations.
This system relies on receiving
specific information from these
stations and only works when the
information is available. It is possible
that a radio station could broadcast
incorrect information that causes the
radio features to work improperly.
If this happens, contact the radio
station.
When information is broadcast from a
RDS station, the station name or call
letters display on the audio screen.
Radio text supporting the currently
playing broadcast may also appear.
Satellite Radio
SiriusXM Radio Service
If equipped, vehicles with a valid
SiriusXM radio subscription can
receive SiriusXM programming.
SiriusXM radio has a wide variety of
programming and commercial-free
music, coast to coast, in digital-quality
sound. In the U.S., see
www.siriusxm.com or call 1-888-601-6296. In Canada, see
www.siriusxm.ca or call
1-877-438-9677.
When SiriusXM is active, the channel
name, number, song title, and artist
appear on the display.
SiriusXM with 360L
SiriusXM with 360L interface has
enhanced in-vehicle listening
experience for subscribers. The
experience now offers more categories
and system learned recommendations
toward discovering more personalized
content.
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 power lines
interfere with radio reception. When
this happens, try reducing the treble
on the radio.

INFOTAINMENT SYSTEM 157
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 Satellite Radio, OnStar, and
GPS (Global Positioning System). Keep
clear of obstructions for clearreception. If the vehicle has a sunroof,
and it is open, reception can also be
affected.

operation or performance. Avoid use if
the content or origin cannot be
trusted.
USB Port
Audio stored on a USB device may be
listened to.
The vehicle may be equipped with two
USB ports in the center console under
the armrest. 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
damaged or cause an electrical
short if the unconnected end comes
in contact with liquids or another
power source such as the accessory
power outlet.

A USB mass storage device can be
connected to the USB port.
Audio extensions supported by the
USB may include:
.MP3
