Auxiliary Roof-Mounted Lamp
If the vehicle has this feature, this button includes wiring
provisions for a dealer or a qualified service center to
install an auxiliary roof lamp.
This button is located on
the overhead console.
When the wiring is connected to an auxiliary roof
mounted lamp, pressing the bottom of the button will
activate the lamp and illuminate an indicator light at the
bottom of this button. Pressing the top of the button will
turn off the roof mounted lamp and indicator.
The emergency roof lamp circuit is fused at 30 amps,
so the total current draw of the attached lamps should
be less than this value. The attachment points for the
roof lamp circuits are two blunt cut wires located above
the overhead console, a dark green switched power
wire and a black ground wire.
For further information on roof mount emergency lamp
installation, please visit the GM Upfitter website at
www.gmupfitters.com or contact your dealer. If the vehicle has this button, the vehicle may have
the snow plow prep package. For further information
see
Adding a Snow Plow or Similar Equipment
on
page 5‑36.
Instrument Panel Brightness
D (Instrument Panel Brightness): This feature
controls the brightness of the instrument panel lights
and is located next to the exterior lamp control.
Push the knob to extend out and then it can be turned.
Turn the knob clockwise or counterclockwise to brighten
or dim the instrument panel lights. Turning the knob to
the farthest clockwise position turns on the dome lamps.
Dome Lamps

{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also
come on. See DIC Warnings and Messages
on
page 4‑61for more information.
Passenger Airbag Status Indicator
If the vehicle has the airbag status indicator pictured
in the following illustration, then the vehicle has a
passenger sensing system for the right front passenger
position. The passenger airbag status indicator is on the
overhead console. See Passenger Sensing System
on
page 2‑93for important safety information.
In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle's sun visors refers to “ADVANCED
AIRBAGS”.
United StatesCanada
When the vehicle is started, the passenger airbag
status indicator will light ON and OFF, or the symbols
for on and off, for several seconds as a system check.
If you are using remote start, if equipped, to start the
vehicle from a distance, you may not see the system
check.
Then, after several more seconds, the status indicator
will light either ON or OFF, or either the on or off symbol
to let you know the status of the right front passenger
frontal airbag.
If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger frontal airbag is enabled (may inflate).
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger sensing
system has turned off the right front passenger frontal
airbag.
4-33

If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be
a problem with the lights or the passenger sensing
system. See your dealer for service.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light
on page 4‑32
for more information, including important safety
information.
Charging System Light
This light comes on briefly
when the ignition key is
turned to START, but the
engine is not running, as
a check to show it is
working.
If it does not, have the vehicle serviced by your dealer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
See DIC Warnings and Messages
on page 4‑61for
more information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.
4-34

If the light comes on while driving, pull off the road and
stop carefully. The pedal might be harder to push or
might go closer to the floor. It can take longer to stop.
If the light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 5‑40.
Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine is
started.
If it does not, have the vehicle serviced by your dealer.
If the system is working normally the indicator light then
goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is not
on, the vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, the
vehicle does not have antilock brakes and there is a
problem with the regular brakes. See
Brake System
Warning Light on page 4‑36.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages
on page 4‑61for all
brake related DIC messages.
StabiliTrak®Indicator Light
For vehicles with the
StabiliTrak®system, this
light comes on briefly
while starting the engine.
If it does not, have the vehicle serviced by your dealer.
If the system is working normally the indicator light then
goes off.
If the light comes on and stays on while driving, there
could be a problem with the StabiliTrak
®system and the
vehicle might need service. When this warning light is
on, the StabiliTrak
®system is off and does not limit
wheel spin.
4-37

When the Light is On Steady
This indicates that one or more of the tires is
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC)
on page 4‑47for more
information. Stop and check the tires as soon as it is
safe to do so. If underinflated, inflate to the proper
pressure. See Inflation - Tire Pressure
on page 6‑72for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the
Tire Pressure Monitor System. The light flashes for
about a minute and stays on steady for the remainder
of the ignition cycle. This sequence repeats with every
ignition cycle. See Tire Pressure Monitor Operation
on
page 6‑74for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on,
but the engine is not
running, as a check to
show it is working. If it
does not, have the vehicle
serviced by your dealer.
If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.

Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
When the oil pressure reaches the low pressure zone,
the OIL PRESSURE LOW STOP ENGINE message
appears in the Driver Information Center (DIC). SeeDIC
Warnings and Messages
on page 4‑61and Engine Oilon page 6‑17for more information.
A reading in the low pressure zone may be caused by
a dangerously low oil level or some other problem
causing low oil pressure. Check the oil as soon as
possible.
{WARNING:
Do not keep driving if the oil pressure is low. The
engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice: Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
If the vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.

There are several conditions that can cause this
message to appear.
.One condition is overheating, which could occur if
StabiliTrak activates continuously for an extended
period of time.
.The message also displays if the brake system
warning light is on. SeeBrake System Warning
Light on page 4‑36.
.The message could display if the stability system
takes longer than usual to complete its diagnostic
checks due to driving conditions.
.The message displays if an engine or vehicle
related problem has been detected and the vehicle
needs service. See your dealer.
.The message also displays if the vehicle is shifted
into 4LO (Two Speed Transfer Case Only).
The message turns off as soon as the conditions that
caused the message to be displayed are no longer
present.
TIGHTEN GAS CAP
This message may display along with the check engine
light on the instrument panel cluster if the vehicle's fuel
cap is not tightened properly. See Malfunction Indicator
Lamp
on page 4‑39. Reinstall the fuel cap fully. See
Filling the Tankon page 6‑11. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap allows
fuel to evaporate into the atmosphere. A few driving
trips with the cap properly installed should turn this light
and message off.
TIRE LEARNING ACTIVE
On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the TPMS is
re-learning the tire positions on your vehicle. The tire
positions must be re-learned after rotating the tires or
after replacing a tire or sensor. See Tire Inspection and
Rotation
on page 6‑78, Tire Pressure Monitor Systemon page 6‑73, and Inflation - Tire Pressureon
page 6‑72for more information.

Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines might be available
in your area. We recommend that you use these
gasolines, if they comply with the specifications
described earlier. However, E85 (85% ethanol) and
other fuels containing more than 10% ethanol must not
be used in vehicles that were not designed for those
fuels.
Notice:This vehicle was not designed for fuel that
contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in the fuel
system and also damage plastic and rubber parts.
That damage would not be covered under the
vehicle warranty.
Some gasolines that are not reformulated for low
emissions can contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. We recommend against
the use of such gasolines. Fuels containing MMT can
reduce the life of spark plugs and the performance of
the emission control system could be affected. The
malfunction indicator lamp might turn on. If this occurs,
return to your dealer for service.Fuel E85 (85% Ethanol)
The 8th digit of the Vehicle Identification Number (VIN)
shows the code letter or number that identifies the
vehicle's engine. The VIN is at the top left of the
instrument panel. See Vehicle Identification Number
(VIN) on page 6‑116.
If the vehicle has the 5.3L V8 engine (Code 0), the
5.3L V8 engine (VIN Code 3), the 6.0L V8 engine
(VIN Code J), or the 6.2L V8 engine (Code 2), you can
use either unleaded gasoline or ethanol fuel containing
up to 85% ethanol (E85). See Fuel
on page 6‑6.
In all other engines, use only the unleaded gasoline
described under Gasoline Octane on page 6‑7.
Only vehicles that have the 5.3L V8 engine (Code 0),
the 5.3L V8 engine (VIN Code 3), the 6.0L V8 engine
(VIN Code J), or the 6.2L V8 engine (Code 2) can use
85% ethanol fuel (E85). We encourage the use of
E85 in vehicles that are designed to use it. The ethanol
in E85 is a “renewable” fuel, meaning it is made from
renewable sources such as corn and other crops.
Many service stations will not have an 85% ethanol
fuel (E85) pump available. The U.S. Department
of Energy has an alternative fuels website
(www.eere.energy.gov/afdc/infrastructure/locator.html)
that can help you find E85 fuel. Those stations that
do have E85 should have a label indicating ethanol
content. Do not use the fuel if the ethanol content is
greater than 85%.

Brake Wear
This vehicle has disc brakes. Disc brake pads have
built-in wear indicators that make a high-pitched
warning sound when the brake pads are worn and new
pads are needed. The sound can come and go or be
heard all the time the vehicle is moving, except when
applying the brake pedal firmly.
{WARNING:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to
an accident. When the brake wear warning sound
is heard, have the vehicle serviced.
Notice: Continuing to drive with worn-out brake
pads could result in costly brake repair. Some driving conditions or climates can cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
the brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to torque specifications in
Capacities and Specifications on page 6‑125.
Brake linings should always be replaced as complete
axle sets.Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign that brake service might be
required.
Brake Adjustment
Every brake stop, the disc brakes adjust for wear.
