166 Infotainment System
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 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.
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 damaged or
cause an electrical short if
the unconnected end comes(Continued)

Infotainment System 183
Global Positioning
System (GPS)
If equipped, the position of the
vehicle is determined by using
satellite signals, various
vehicle signals, and map data.
At times, other interference
such as the satellite condition,
road configuration, condition
of the vehicle, and/or other
circumstances can affect the
navigation system's ability to
determine the accurate
position of the vehicle.
The GPS shows the current
position of the vehicle using
signals sent by GPS satellites.
When the vehicle is not
receiving signals from the
satellites, a symbol appears in
the status bar.
This system might not be
available or interference can
occur if any of the following
are true:
.Signals are obstructed by
tall buildings, trees, large
trucks, or a tunnel.
.Satellites are being repaired
or improved.
For more information if the
GPS is not functioning
properly, see Problems with
Route Guidance 0184 and
If the System Needs Service
0 184.
Vehicle Positioning
At times, the position of the
vehicle on the map could be
inaccurate due to one or more
of the following reasons:
.The road system has
changed.
.The vehicle is driving on
slippery road surfaces such
as sand, gravel, or snow.
.The vehicle is traveling on
winding roads or long,
straight roads.
.The vehicle is approaching a
tall building or a large
vehicle.
.The surface streets run
parallel to a freeway.
.The vehicle has been
transferred by a vehicle
carrier or a ferry.
.The current position
calibration is set incorrectly.
.The vehicle is traveling at
high speed.
.The vehicle changes
directions more than once,
or the vehicle is turning on a
turn table in a parking lot.
.The vehicle is entering
and/or exiting a parking lot,
garage, or a lot with a roof.
.The GPS signal is not
received.
.A roof carrier is installed on
the vehicle.
.Tire chains are installed on
the vehicle.
.The tires are replaced
or worn.
.The tire pressure for the
tires is incorrect.
.This is the first navigation
use after the map data is
updated.

Driving and Operating 235
.Avoid stressful
conversations while driving,
whether with a passenger or
on a cell phone.
{Warning
Taking your eyes off the
road too long or too often
could cause a crash
resulting in injury or death.
Focus your attention on
driving.
Refer to the infotainment
section for more information
on using that system and the
navigation system, if equipped,
including pairing and using a
cell phone.
Defensive Driving
Defensive driving means
“always expect the
unexpected.” The first step in
driving defensively is to wear
the seat belt. See Seat Belts
0 49.
.Assume that other road
users (pedestrians,
bicyclists, and other drivers)
are going to be careless and
make mistakes. Anticipate
what they may do and be
ready.
.Allow enough following
distance between you and
the driver in front of you.
.Focus on the task of driving.
Impaired Driving
Death and injury associated
with impaired driving is a
global tragedy.
{Warning
Drinking alcohol or taking
drugs and then driving is
very dangerous. Your
reflexes, perceptions,
attentiveness, and judgment
can be affected by even a
small amount of alcohol or
drugs. You can have a
(Continued)
Warning (Continued)
serious—or even fatal —
collision if you drive after
drinking or taking drugs.
Do not drive while under the
influence of alcohol or drugs,
or ride with a driver who has
been drinking or is impaired
by drugs. Find alternate
transportation home; or if
you are with a group,
designate a driver who will
remain sober.
Control of a Vehicle
Braking, steering, and
accelerating are important
factors in helping to control a
vehicle while driving.
Braking
Braking action involves
perception time and reaction
time. Deciding to push the
brake pedal is perception time.
Actually doing it is
reaction time.

346 Driving and Operating
{Warning
AEB may automatically
brake the vehicle suddenly in
situations where it is
unexpected and undesired.
It could respond to a turning
vehicle ahead, guardrails,
signs, and other non-moving
objects. To override AEB,
firmly press the accelerator
pedal, if it is safe to do so.
Intelligent Brake
Assist (IBA)
IBA may activate when the
brake pedal is applied quickly
by providing a boost to
braking based on the speed of
approach and distance to a
vehicle ahead.Minor brake pedal pulsations
or pedal movement during this
time is normal and the brake
pedal should continue to be
applied as needed. IBA will
automatically disengage only
when the brake pedal is
released.
{Warning
IBA may increase vehicle
braking in situations when it
may not be necessary. You
could block the flow of
traffic. If this occurs, take
your foot off the brake pedal
and then apply the brakes as
needed.
AEB and IBA can be disabled
through vehicle settings. To
view available settings for this
feature, touch the Settings
icon on the infotainment home
page. Select “Vehicle”to
display the list of available
options and select “Collision/
Detection Systems”.
{Warning
Using AEB or IBA while
towing a trailer could cause
you to lose control of the
vehicle and crash. Turn the
system to Alert or Off when
towing a trailer.
A system unavailable message
may display if:
.The front of the vehicle or
windshield is not clean.
.Heavy rain or snow is
interfering with object
detection.
.There is a problem with the
StabiliTrak/Electronic
Stability Control (ESC)
system.
The AEB system does not
need service.

Vehicle and Power Issues
OnStar services require a
vehicle electrical system,
wireless service, and GPS
satellite technologies to be
available and operating for
features to function properly.
These systems may not
operate if the battery is
discharged or disconnected.
Add-on Electrical
Equipment
The OnStar system is
integrated into the electrical
architecture of the vehicle. Do
not add any electrical equipment. See Add-On
Electrical Equipment
0366.
Added electrical equipment
may interfere with the
operation of the OnStar
system and cause it to not
operate.
Vehicle Software Updates
OnStar or GM may remotely
deliver software updates or
changes to the vehicle without
further notice or consent.
These updates or changes
may enhance or maintain

updates or changes may
affect or erase data or
settings that are stored in the
vehicle, such as saved
navigation destinations or
pre-set radio stations. Neither
OnStar nor GM is responsible
for any affected or erased
data or settings. These
updates or changes may also
collect personal information.
Such collection is described in the OnStar privacy statement
or separately disclosed at the
