188 Climate Controls
air temperature and helps maintain
the temperature inside the vehicle.
Any cover on the front of the
vehicle, including a snowplow, could
cause a false reading in the
displayed temperature.
The climate control system uses the
information from these sensors to
maintain comfort settings by
adjusting the outlet temperature, fan
speed, and air delivery mode. The
system may also supply cooler air to
the side of the vehicle facing the
sun. The recirculation mode will also
be used as needed to maintain cool
outlet temperatures.
Rear Climate Control
System
The rear climate control system is
located on the rear of the center
console storage. The rear climate
settings can be adjusted with this
system.
1. Fan Control
2. AUTO (Automatic Operation)

4. TEMP (Temperature Control)
5. Heated Rear Seats (If Equipped)
If the dual automatic climate control
system rear climate control lockout
feature is locked, the rear climate
control settings can only be
adjusted from the front seat.
Automatic Operation
AUTO : Press AUTO to control the
inside temperature, air delivery, and
fan speed. A is indicated in the
display when automatic operation is
active. If any of the climate control
settings are manually adjusted, this
cancels full automatic operation.
The display only indicates climate
control functions when the system is
in rear independent mode.
Manual Operation
9(Fan Control) : Turn clockwise
or counterclockwise to increase or
decrease the fan speed. Turn
completely counterclockwise to turn
the fan/power off.
TEMP (Temperature Control) :
Turn clockwise or counterclockwise
to increase or decrease the airflow
temperature into the passenger
area. If the SYNC button is pressed
on the front climate controls, the
rear climate temperature is linked to
the driver temperature setting.
MODE (Air Delivery Mode
Control) : Press to change the
direction of the airflow in the vehicle.

1. Slider Knob
2. Thumbwheel
Move the slider knobs (1) to change
the direction of the airflow.
Use the thumbwheels (2) near the
air vents to open or close off the
airflow. Operation Tips
.
Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
could block the flow of air into
the vehicle.
. When you enter a vehicle in cold
weather, press the fan up button
to the maximum fan level before
driving. This helps clear the
intake ducts of snow and
moisture, and reduces the
chance of fogging the inside of
the window.
. Keep the air path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
. Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.

208 Driving and Operating
(GVWR). The GVWR includes
the weight of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label also
may show the maximum weights
for the front and rear axles,
called Gross Axle Weight Rating
(GAWR). To find out the actual
loads on the front and rear
axles, weigh the vehicle at a
weigh station. Your dealer can
help with this. Be sure to spread
your load equally on both sides
of the centerline.
The Certification/Tire label may
also include information about
the Front Axle Reserve
Capacity.
{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
(Continued)
Warning (Continued)
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
Caution
Overloading the vehicle may
cause damage. Repairs would not
be covered by the vehicle
warranty. Do not overload the
vehicle.
The label will help decide how
much cargo and installed
equipment the truck can carry.
Using heavier suspension
components to get added
durability might not change the weight ratings. Ask your dealer
to help load the vehicle the
right way.
{Warning
Things you put inside the
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
.Put things in the cargo
area of the vehicle. Try to
spread the weight evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
.Do not leave an
unsecured child restraint
in the vehicle.
.When you carry
something inside the
vehicle, secure it
whenever you can.

The transmitter must be in the
vehicle for the system to operate.
If the pushbutton start is not
working, the vehicle may be near a
strong radio antenna signal causing
interference to the Keyless Access system. See
Remote Keyless Entry
(RKE) System Operation (Key
Access) 032 orRemote Keyless
Entry (RKE) System Operation
(Keyless Access) 034.
To shift out of P (Park), the vehicle

Power (RAP) 0216.
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC).
See Transmission Messages 0161.

The United States version of a
metric tire sizing system. The
letter P as the first character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association.
(2) Tire Width
:The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio
:A two-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 75, as shown in
item C of the tire illustration, it would mean that the tire's
sidewall is 75 percent as high as
it is wide.
(4) Construction Code
:A letter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter
:Diameter of
the wheel in inches.
(6) Service Description
:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight
:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
windows, power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire's height to its width.
