Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle should
be serviced. There are parts of the
airbag system in several places around
the vehicle. Your dealer and the
service manual have information
about servicing the vehicle and the
airbag system. To purchase a service
manual, seePublication Ordering
Information 0383.
{Warning
For up to 10 seconds after the
vehicle is turned off and the battery
is disconnected, an airbag can still
inflate during improper service. You
can be injured if you are close to an
airbag when it inflates. Avoid
yellow connectors. They are
probably part of the airbag system.
Be sure to follow proper service
procedures, and make sure the
person performing work for you is
qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet metal
may keep the airbag system from
working properly.
The operation of the airbag system
can also be affected by changing,
including improperly repairing or
replacing, any parts of the following:
.Airbag system, including airbag
modules, front or side impact
sensors, sensing and diagnostic
module, or airbag wiring
.Front seats, including stitching,
seams or zippers
.Seat belts
.Steering wheel, instrument panel,
overhead console, ceiling trim,
or pillar garnish trim
.Inner door seals, including speakers
Your dealer and the service manual
have information about the location of
the airbag modules and sensors, sensing and diagnostic module, and
airbag wiring along with the proper
replacement procedures.
In addition, the vehicle has a
passenger sensing system for the front
outboard passenger position, which
includes sensors that are part of the
passenger seat. The passenger sensing
system may not operate properly if
the original seat trim is replaced with
non-GM covers, upholstery, or trim; or
with GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad or
device, installed under or on top of
the seat fabric, could also interfere
with the operation of the passenger
sensing system. This could either
prevent proper deployment of the
passenger airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). See
Passenger Sensing
System 060.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0326 for additional important
information.

Cargo Tie-Downs
The vehicle has four cargo tie-downs
in the rear compartment.
Roof Rack System{
Warning
If something is carried on top of the
vehicle that is longer or wider than
the roof rack —like paneling,
plywood, or a mattress —the wind
can catch it while the vehicle is
being driven. The item being carried
could be violently torn off, and this (Continued)
Warning (Continued)
could cause a collision and damage
the vehicle. Never carry something
longer or wider than the roof rack
on top of the vehicle unless using a
GM certified accessory carrier.
If equipped, the roof rack can be used
to load items. For roof racks that do
not have crossrails included, GM
certified crossrails can be purchased
as an accessory. See your dealer.
Caution
Loading cargo on the roof rack that
weighs more than 100 kg (220 lb) or
hangs over the rear or sides of the
vehicle may damage the vehicle. Do
not load cargo exceeding 100 kg
(220 lbs) and always load cargo so
that it rests evenly between the
crossrails and does not block the
vehicle lamps or windows. Fasten
the cargo securely.
To prevent damage or loss of cargo
when driving, check to make sure
crossrails and cargo are securely
fastened. Loading cargo on the roof
rack will make the vehicle’s center of
gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden
braking, or abrupt maneuvers;
otherwise it may result in loss of
control. If driving for a long distance,
on rough roads, or at high speeds,
occasionally stop the vehicle to make
sure the cargo remains in its place. Do
not exceed the maximum vehicle

f:Pull the windshield wiper lever
toward you to spray windshield
washer fluid and activate the wipers.
The wipers will continue until the
lever is released or the maximum
wash time is reached. When the
windshield wiper lever is released,
additional wipes may occur depending
on how long the windshield washer
has been activated. See Washer Fluid
0 295 for information on filling the
windshield washer fluid reservoir.
{Warning
In freezing weather, do not use the
washer until the windshield is
warmed. Otherwise the washer fluid
can form ice on the windshield,
blocking your vision.
{Warning
Before driving the vehicle, always
clear snow and ice from the hood,
windshield, roof, and rear of the
vehicle, including all lamps and
(Continued)
Warning (Continued)
windows. Reduced visibility from
snow and ice buildup could lead to
a crash.
Clear snow and ice from the wiper
blades and windshield before using
them. If frozen to the windshield,
carefully loosen or thaw them.
Damaged blades should be replaced.
See Wiper Blade Replacement 0299.
Heavy snow or ice can overload the
wiper motor. See Electrical System
Overload 0302.
Wiper Parking
If the ignition is turned off while the
wipers are on LO, HI, or AUTO with
Rainsense turned off, they will
immediately stop.
If the windshield wiper lever is then
moved to OFF before the driver door is
opened or within 10 minutes, the
wipers will restart and move to the
base of the windshield. If the ignition is turned off while the
wipers are performing wipes due to
windshield washing or Rainsense, the
wipers continue to run until they
reach the base of the windshield.
Rainsense
If equipped with Rainsense and the
feature is turned on, a sensor near the
top center of the windshield detects
the amount of water on the
windshield and controls the frequency
of the windshield wiper based on the
current sensitivity setting.
Keep this area of the windshield clear
of debris to allow for best system
performance.
AUTO :
Move the windshield wiper
lever to AUTO. Turn the band on the
wiper lever to adjust the sensitivity.

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

14584367) - 2021 - CRC - 10/14/20
INFOTAINMENT SYSTEM 163
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 0163 and
If the System Needs Service 0164.
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.
.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.

Loading the Vehicle for Off-Road
Driving
{Warning
.Unsecured cargo on the load
floor can be tossed about when
driving over rough terrain. You or
your passengers can be struck by
flying objects. Secure the cargo
properly.
.Keep cargo in the cargo area as
far forward and as low as
possible. The heaviest things
should be on the floor, forward
of the rear axle.
.Heavy loads on the roof raise the
vehicle's center of gravity,
making it more likely to roll over.
You can be seriously or fatally
injured if the vehicle rolls over.
Put heavy loads inside the cargo
area, not on the roof.
For more information about loading
the vehicle, see Vehicle Load Limits
0 215.
Environmental Concerns
.Always use established trails, roads,
and areas that have been set aside
for public off-road recreational
driving and obey all posted
regulations.
