{Warning
If the key is unintentionally rotated while
the vehicle is running, the ignition could
be moved out of the RUN position. This
could be caused by heavy items hanging
from the key ring, or by large or long
items attached to the key ring that could
be contacted by the driver or steering
wheel. If the ignition moves out of the
RUN position, the engine will shut off,
braking and steering power assist may be
impacted, and airbags may not deploy.
To reduce the risk of unintentional
rotation of the ignition key, do not
change the way the ignition key and
Remote Keyless Entry (RKE) transmitter,
if equipped, are connected to the
provided key rings.
The ignition key and key rings, and RKE
transmitter, if equipped, are designed to
work together as a system to reduce the
risk of unintentionally moving the key out
of the RUN position. The ignition key has a
small hole to allow attachment of the
provided key ring. It is important that any
replacement ignition keys have a small hole.
See your dealer if a replacement key is
required.
The combination and size of the rings that
came with your keys were specifically
selected for your vehicle. The rings are
connected to the key like two links of a
chain to reduce the risk of unintentionally
moving the key out of the RUN position. Do
not add any additional items to the ringattached to the ignition key. Attach
additional items only to the second ring,
and limit added items to a few essential
keys or small, light items no larger than an
RKE transmitter.
Interference from radio-frequency
identification (RFID) tags may prevent the
key from starting the vehicle. Keep RFID
tags away from the key when starting the
vehicle.
The key that is part of the Remote Keyless
Entry (RKE) transmitter can be used for the
ignition and all locks.

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 050.
If the vehicle has rollover roof-rail airbags,
see Different Size Tires and Wheels 0212 for
additional important information.
If the vehicle must be modified because you
have a disability and have questions about
whether the modifications will affect the
vehicle's airbag system, or if you have
questions about whether the airbag system
will be affected if the vehicle is modified for
any other reason, call Customer Assistance.
See Customer Assistance Offices 0251.
Airbag System Check
The airbag system does not need regularly
scheduled maintenance or replacement.
Make sure the airbag readiness light is
working. See Airbag Readiness Light 082.
Caution
If an airbag covering is damaged, opened,
or broken, the airbag may not work
properly. Do not open or break the airbag
coverings. If there are any opened or
broken airbag coverings, have the airbag

covering and/or airbag module replaced.
For the location of the airbags, see Where
Are the Airbags? 046. See your dealer
for service.
Replacing Airbag System Parts
after a Crash
{Warning
A crash can damage the airbag systems
in the vehicle. A damaged airbag system
may not properly protect you and your
passenger(s) in a crash, resulting in
serious injury or even death. To help
make sure the airbag systems are
working properly after a crash, have
them inspected and any necessary
replacements made as soon as possible.
If an airbag inflates, you will need to
replace airbag system parts. See your dealer
for service.

128 Driving and Operating
Driving Information
Driver Behavior
Driving is an important responsibility. Driver
behavior, the driving environment, and the
vehicle's design all affect how well a vehicle
performs.
Being aware of these factors can help in
understanding how the vehicle handles and
what can be done to avoid many types of
crashes, including a rollover crash.
Most serious injuries and fatalities to
unbelted occupants can be reduced or
prevented by the use of seat belts. In a
rollover crash, an unbelted person is
significantly more likely to die than a
person wearing a seat belt. In addition,
avoiding excessive speed, sudden or abrupt
turns, and drunken or aggressive driving can
help make trips safer and avoid the
possibility of a crash.
Driving Environment
Be prepared for driving in inclement
weather, at night, or during other times
where visibility or traction may be limited,such as on curves, slippery roads, or hilly
terrain. Unfamiliar surroundings can also
have hidden hazards.
Vehicle Design
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
This is because they have a higher ground
clearance and a narrower track or shorter
wheelbase than passenger cars, which makes
them more capable for off-road driving.
While these design characteristics provide
the driver with a better view of the road,
these vehicles do have a higher center of
gravity than other types of vehicles.
A utility vehicle does not handle the same
as a vehicle with a lower center of gravity,
like a car, in similar situations.
Safe driver behavior and understanding of
the environment can help avoid a rollover
crash in any type of vehicle, including utility
vehicles.
Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here
are some driving tips to get the best fuel
economy possible:
.Set the climate controls to the desired
temperature after the engine is started,
or turn them off when not required.
.Avoid fast starts and accelerate smoothly.
.Brake gradually and avoid abrupt stops.
.Avoid idling the engine for long periods
of time.
.When road and weather conditions are
appropriate, use cruise control.
.Always follow posted speed limits or
drive more slowly when conditions
require.
.Keep vehicle tires properly inflated.
.Combine several trips into a single trip.
.Replace the vehicle's tires with the same
TPC Spec number molded into the tire's
sidewall near the size.
.Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms and can
take your focus from the task of driving.
Exercise good judgment and do not let other
activities divert your attention away from
the road. Many local governments have

150 Driving and Operating
2. Press the + (plus) end of the button onthe side of the shift lever to upshift,
or press the −(minus) end of the button
to downshift.
The instrument cluster will change from the
currently displayed message to the letter
“M,” for Manual position, and a number
indicating the requested gear.
While using the DSC feature, the
transmission will have firmer shifting and
sportier performance. This can be used for
sport driving or when climbing hills to stay
in gear longer or to downshift for more
power or engine braking.
The transmission will only allow you to shift
into gears appropriate for the vehicle speed
and engine revolutions per minute (rpm):
.The transmission will not allow shifting to
the next higher gear if the vehicle speed
or engine rpm is too low.
.The transmission will not allow shifting to
the next lower gear if the vehicle speed
or engine rpm is too high. Automatic Transmission Adaptation Feature
While the vehicle is being driven and gear
shifting takes place, the transmission will
learn and adapt. This increases durability
and maintains the best shift quality of the
life of the vehicle.
During vehicle break-in (initial driving), it is
normal to experience some shift bumps.
Shift quality will improve with the normal
gear shifting as the transmission learns and
adapts.
Drive Systems
All-Wheel Drive
If equipped, this feature transfers engine
power, as required, to all four wheels. It is
fully automatic, and adjusts itself as needed
for road conditions.
When using a compact spare tire on an
All-Wheel Drive (AWD) vehicle, the system
automatically detects the compact spare and
disables AWD to protect the system.
A Driver Information Center (DIC) message
will display on the instrument cluster. See
Vehicle Messages
092. To restore AWD
operation and prevent excessive wear on the system, replace the compact spare with a
full-size tire as soon as possible. See
Compact Spare Tire
0220.
AWD will be disabled and the message will
display if there is excessive wheel spin.
When the system cools down, AWD will be
restored.
Brakes
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
ABS performs a system check when the
vehicle is first driven. A momentary motor
or clicking noise may be heard while this
test is going on, and the brake pedal may
move slightly. This is normal.
If there is a problem with ABS, this warning
light stays on. See Antilock Brake System
(ABS) Warning Light 086.

sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists.
When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as
intended. TPMS malfunctions may occur for
a variety of reasons, including the
installation of replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on
your vehicle to ensure that the replacement
or alternate tires and wheels allow the
TPMS to continue to function properly.
SeeTire Pressure Monitor Operation 0207.
See Radio Frequency Statement 0257.
Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure
Monitor System (TPMS). The TPMS is
designed to warn the driver when a low tire
pressure condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire and
wheel assembly. The TPMS sensors monitor the air pressure in the tires and transmit the
tire pressure readings to a receiver located
in the vehicle.
When a low tire pressure condition is
detected, the TPMS illuminates the low tire
pressure warning light located on the
instrument cluster. If the warning light
comes on, stop as soon as possible and
inflate the tires to the recommended
pressure shown on the Tire and Loading
Information label. See
Vehicle Load Limits
0 134.
A message to check the pressure in a
specific tire may display in the Driver
Information Center (DIC). The low tire
pressure warning light and the DIC warning
message, if equipped, come on at each
ignition cycle until the tires are inflated to
the correct inflation pressure. Using the DIC,
it may be possible to view the tire pressure
levels. For additional information and details
about the DIC operation and displays, see
Driver Information Center (DIC) 090. The low tire pressure warning light may
come on in cool weather when the vehicle is
first started, and then turn off as the vehicle
is driven. This could be an early indicator
that the air pressure is getting low and
needs to be inflated to the proper pressure.
A Tire and Loading Information label shows
the size of the original equipment tires and
the correct inflation pressure for the tires
when they are cold. See
Vehicle Load Limits
0 134, for an example of the Tire and
Loading Information label and its location.
Also see Tire Pressure 0205.
The TPMS can warn about a low tire
pressure condition, but it does not replace
normal tire maintenance. See Tire Inspection
0 209, Tire Rotation 0209, and Tires0199.
Caution
Tire sealant materials are not all the
same. A non-approved tire sealant could
damage the TPMS sensors. TPMS sensor
damage caused by using an incorrect tire
sealant is not covered by the vehicle
warranty. Always use only the GM
approved tire sealant available through
your dealer or included in the vehicle.

sensor matching process is no longer
active. The TIRE LEARN or TIRE LEARNING
ACTIVE message on the DIC display
screen goes off.
12. Turn the vehicle off.
13. Set all four tires to the recommended air pressure level as indicated on the Tire
and Loading Information label.
Tire Inspection
We recommend that the tires, including
the spare tire, if the vehicle has one, be
inspected for signs of wear or damage
at least once a month. Replace the tire if:
.The indicators at three or more
places around the tire can be seen.
.There is cord or fabric showing
through the tire's rubber.
.The tread or sidewall is cracked, cut,
or snagged deep enough to show
cord or fabric.
.The tire has a bump, bulge, or split.
.The tire has a puncture, cut, or other
damage that cannot be repaired well
because of the size or location of the
damage.
Tire Rotation
Tires should be rotated every 12 000 km
(7,500 mi). See
Maintenance Schedule
0 235.
Tires are rotated to achieve a more
uniform wear for all tires. The first
rotation is the most important.
Anytime unusual wear is noticed, rotate
the tires as soon as possible, check for
proper tire inflation pressure, and check
for damaged tires or wheels. If the

2021 - CRC - 8/21/20
212 Vehicle Care
GM recommends replacing worn tires in
complete sets of four. Uniform tread
depth on all tires will help to maintain
the performance of the vehicle. Braking
and handling performance may be
adversely affected if all the tires are not
replaced at the same time. If proper
rotation and maintenance have been
done, all four tires should wear out at
about the same time. However, if it is
necessary to replace only one axle set
of worn tires, place the new tires on
the rear axle. SeeTire Rotation0209.
{Warning
Tires could explode during improper
service. Attempting to mount or
dismount a tire could cause injury or
death. Only your dealer or authorized
tire service center should mount or
dismount the tires.
{Warning
Mixing tires of different sizes (other
than those originally installed on the
vehicle), brands, tread patterns,
or types may cause loss of vehicle
control, resulting in a crash or other
vehicle damage. Use the correct size,
brand, and type of tire on all wheels.
{Warning
Using bias-ply tires on the vehicle
may cause the wheel rim flanges to
develop cracks after many miles of
driving. A tire and/or wheel could fail
suddenly and cause a crash. Use only
radial-ply tires with the wheels on
the vehicle.
Winter tires with the same speed rating
as the original equipment tires may not
be available for H, V, W, Y and ZR
speed rated tires. Never exceed the
winter tires’ maximum speed capability
when using winter tires with a lower
speed rating. If the vehicle tires must be replaced
with a tire that does not have a TPC
Spec number, make sure they are the
same size, load range, speed rating, and
construction (radial) as the original
tires.
The Tire and Loading Information label
indicates the original equipment tires
on the vehicle. See
Vehicle Load Limits
0 134.Different Size Tires and Wheels
If wheels or tires are installed that are a
different size than the original equipment
wheels and tires, vehicle performance,
including its braking, ride and handling
characteristics, stability, and resistance to
rollover may be affected. If the vehicle has
electronic systems such as antilock brakes,
rollover airbags, traction control, electronic
stability control, or All-Wheel Drive, the
performance of these systems can also be
affected.

Vehicle Care 213
{Warning
If different sized wheels are used, there
may not be an acceptable level of
performance and safety if tires not
recommended for those wheels are
selected. This increases the chance of a
crash and serious injury. Only use GM
specific wheel and tire systems developed
for the vehicle, and have them properly
installed by a GM certified technician.
See Buying New Tires 0211 and
Accessories and Modifications 0167.
Uniform Tire Quality Grading
The following information relates to the
system developed by the United States
National Highway Traffic Safety
Administration (NHTSA), which grades
tires by treadwear, traction, and
temperature performance. This applies
only to vehicles sold in the United
States. The grades are molded on the
sidewalls of most passenger car tires.
The Uniform Tire Quality Grading
(UTQG) system does not apply to deep
tread, winter tires, compact spare tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
While the tires available on General
Motors passenger cars and light trucks
may vary with respect to these grades,
they must also conform to federal
safety requirements and additional
General Motors Tire Performance
Criteria (TPC) standards.
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:Treadwear 200 Traction AA Temperature A
All Passenger Car Tires Must Conform to
Federal Safety Requirements In Addition
To These Grades.
Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and one-half (1½)times as well on the government course
as a tire graded 100. The relative
performance of tires depends upon the
actual conditions of their use, however,
and may depart significantly from the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction
The traction grades, from highest to
lowest, are AA, A, B, and C. Those
grades represent the tire's ability to
stop on wet pavement as measured
under controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have
poor traction performance. Warning:
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
