Driving with IntelliBeam
The system only activates the high beams
when driving over 40 km/h (25 mph).
The blue high-beam on light appears on the
instrument cluster when the high beams
are on.
There is a sensor near the top center of the
windshield that automatically controls the
system. Keep this area of the windshield
clear of debris to allow for best system
performance.
The high-beam headlamps remain on, under
the automatic control, until one of the
following situations occurs:
.The system detects an approaching
vehicle's headlamps.
.The system detects a preceding vehicle's
taillamps.
.The outside light is bright enough that
high-beam headlamps are not required.
.The vehicle's speed drops below 20 km/h
(12 mph).
.The IntelliBeam system is disabled by the
button on the turn signal lever. If this
happens, press the button on the end of
the turn signal lever when the exterior
lamp control is in the AUTO or
2
position. The instrument cluster light will
come on to indicate the IntelliBeam
system is reactivated.
The high beams may not turn off
automatically if the system cannot detect
another vehicle's lamps because of any of
the following:
.The other vehicle's lamps are missing,
damaged, obstructed from view,
or otherwise undetected.
.The other vehicle's lamps are covered
with dirt, snow, and/or road spray.
.The other vehicle's lamps cannot be
detected due to dense exhaust, smoke,
fog, snow, road spray, mist, or other
airborne obstructions.
.The vehicle's windshield is dirty, cracked,
or obstructed by something that blocks
the view of the light sensor.
.The vehicle is loaded such that the front
end points upward, causing the light
sensor to aim high and not detect
headlamps and taillamps.
.The vehicle is being driven on winding or
hilly roads.
The automatic high-beam headlamps may
need to be disabled if any of the above
conditions exist.

If the lever is moved momentarily to the
lane change position, the arrow will flash
three times. It will flash six times if Tow/
Haul Mode is active.
The lever returns to its starting position
when it is released.
If after signaling a turn or lane change, the
arrow flashes rapidly or does not come on, a
signal bulb may be burned out.
Have any burned out bulbs replaced. If a
bulb is not burned out, check the fuse. See
Instrument Panel Fuse Block 0288.
Fog Lamps
The ignition and parking lamps or
headlamps must be on for the front fog
lamps to work.
If equipped, the front fog lamps provide
extra illumination to the sides of the road
and improve visibility in fog or snow.
#:Turn the band down and release to
turn the fog lamps on or off. An indicator
light on the instrument cluster comes on
when the fog lamps are on.

144 Infotainment System
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 other communication
systems, 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

.The 12-volt battery has been disconnected
for several days.
.The vehicle is driving in heavy traffic
where driving is at low speeds, and the
vehicle is stopped and started repeatedly.
Problems with Route Guidance
Inappropriate route guidance can occur
under one or more of the following
conditions:
.The turn was not made on the road
indicated.
.Route guidance might not be available
when using automatic rerouting for the
next right or left turn.
.The route might not be changed when
using automatic rerouting.
.There is no route guidance when turning
at an intersection.
.Plural names of places might be
announced occasionally.
.It could take a long time to operate
automatic rerouting during high-speed
driving.
.Automatic rerouting might display a route
returning to the set waypoint if heading
for a destination without passing through
a set waypoint.
.The route prohibits the entry of a vehicle
due to a regulation by time or season or
any other regulation which may be given.
.Some routes might not be searched.
.The route to the destination might not be
shown if there are new roads, if roads
have recently changed, or if certain roads
are not listed in the map data. See Maps
0 151.
To recalibrate the vehicle's position on the
map, park with the vehicle running for two
to five minutes, until the vehicle position
updates. Make sure the vehicle is parked in
a location that is safe and has a clear view

Driving and Operating 199
Winter Driving
Driving on Snow or IceCaution
To avoid damage to the wheels and
brake components, always clear snow and
ice from inside the wheels and
underneath the vehicle before driving.
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on Traction Control. See Traction
Control/Electronic Stability Control 0218.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0215.
.Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
.Turn off cruise control.
.Select All-Wheel Drive (AWD) Mode for
vehicles equipped with AWD. Select
Snow/Ice Mode for FWD only vehicles.
See Driver Mode Control 0220 and
All-Wheel Drive 0215.
Blizzard Conditions
Stop the vehicle in a safe place and signal
for help. Stay with the vehicle unless there
is help nearby. If possible, use Roadside
Assistance. See Roadside Assistance Program
0 354. To get help and keep 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.
.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 0210.
