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,

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.

everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine
exhaust under the vehicle.
This may cause exhaust
gases to get inside. Engine
exhaust contains carbon
monoxide (CO), which cannot
be seen or smelled. It can
cause unconsciousness and
even death.
If the vehicle is stuck
in snow:
.Clear snow from the base
of the vehicle, especially
any blocking the
exhaust pipe.
(Continued)
Warning (Continued)
.Open a window about
5 cm (2 in) on the vehicle
side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the
highest setting. See
“Climate Control Systems.”
For more information about
CO, see Engine Exhaust
0 271.
To save fuel, run the engine
for short periods to warm the
vehicle and then shut the

speed. This keeps the battery
charged to restart the vehicle
and to signal for help with the
headlamps. Do this as little as
possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle
when stuck in sand, mud, ice,
or snow.
The Traction Control System
(TCS) can often help to free a
stuck vehicle. See Traction
Control/Electronic Stability

could be injured. The vehicle
can overheat, causing an
engine compartment fire or
other damage. Spin the
wheels as little as possible
and avoid going above
56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left
and right to clear the area
around the front wheels. Turn
off any traction system. Shift
back and forth between
R (Reverse) and a low forward
gear, spinning the wheels as
little as possible. To prevent
transmission wear, wait until
the wheels stop spinning
before shifting gears. Release
the accelerator pedal while
shifting, and press lightly on
the accelerator pedal when
the transmission is in gear.
Slowly spinning the wheels in
the forward and reverse directions causes a rocking
motion that could free the
vehicle. If that does not get
the vehicle out after a few
tries, it might need to be
towed out. If the vehicle does
need to be towed out, see
