Heated Windshield Washer
For vehicles with the heated windshield washer uid
system it can be used to help clear ice, snow, tree sap,
or bugs from your windshield.
The button is located
in the switchbank under
the climate controls.
Push the heated washer uid button to activate the
heated windshield washer uid system. The indicator
light will ash. This activation initiates four heated
wash/wipe cycles. The rst heated wash/wipe cycle may
take up to 40 seconds to occur, depending on outside
temperature. After the rst wash/wipe cycle, it may take
up to 20 seconds for each of the remaining cycles to
begin. Press the button again to turn off the heated
windshield washer uid system or it will automatically
turn off after four wipe cycles have been completed.
When the heated windshield washer uid system is
activated under certain outside temperature conditions,
steam may ow out of the washer nozzles for a short
period of time before washer uid is sprayed. This is
a normal condition.
Cruise Control
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause excessive wheel slip,
and you could lose control. Do not use
cruise control on slippery roads.
With cruise control, you can maintain a speed of
about 25 mph (40 km/h) or more without keeping
your foot on the accelerator. This can really help on
long trips. Cruise control does not work at speeds
below about 25 mph (40 km/h).
When you apply your brakes, cruise control is turned off.
If your vehicle has the StabiliTrak
®system and begins
to limit wheel spin while you are using cruise control,
the cruise control will automatically disengage. See
StabiliTrak
®System on page 4-6. When road conditions
allow you to safely use it again, you may turn the
cruise control back on.

Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the voltage
is raised slightly to quickly put the charge back in.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not be
spinning fast enough at idle to produce all the power
that is needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate control fan
at high speed, heated seats, engine cooling fans,
trailer loads, and loads plugged into accessory
power outlets.EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable
to the driver. If so, a Driver Information Center (DIC)
message might be displayed, such as Battery Saver
Active or Service Battery Charging System. If this
message is displayed, it is recommended that the
driver reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 3-50.
Battery Run-Down Protection
This feature shuts off the dome lamps if they are
left on for more than 10 minutes when the ignition
is in LOCK. This will help prevent the battery from
running down.

Climate Controls
Dual Automatic Climate Control
System
With this system, you can control the heating, cooling,
and ventilation in your vehicle. Your vehicle also has
a ow-through ventilation system described later in
this section.
You can select different climate control settings for
the driver and passengers.
Driver’s Side Temperature Knob
The driver’s side knob is used to adjust the temperature
of the air coming through the system on the driver’s
side. The temperature can be adjusted even if the
system is turned off. This is possible since outside
air will always ow through the system as the vehicle is
moving forward unless it is set to recirculation mode.
See “Recirculation” later in this section.
Turn the knob counterclockwise or clockwise to lower
or increase the temperature inside the vehicle. The
display will show the temperature setting decreasing
or increasing.
Passenger’s Side Temperature Knob
The passenger’s side knob can be used to change
the temperature of the air coming through the system
on the passenger’s side of the vehicle. The temperature
can be adjusted even if the system is turned off. This
is possible since outside air will always ow through
the system as the vehicle is moving forward unless it
is set to recirculation mode. See “Recirculation” later
in this section.
Turn the knob counterclockwise or clockwise to lower
or increase the temperature inside the vehicle. The
display will show the temperature setting decreasing
or increasing.
Set the passenger’s temperature setting to match the
driver’s temperature setting by pressing the passenger
power knob. Climate Control with Cooled and Heated Seats shown

Automatic Operation
AUTO (Automatic):When automatic operation is
active the system will control the inside temperature,
the air delivery, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change to
show the current temperature(s) and AUTO will
appear. The current delivery mode and fan speed will
also be displayed for approximately ve seconds.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will
run when the outside temperature is over about
40°F (4°C). The air inlet will normally be set to
outside air. If it is hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down your vehicle. The light on the
button will come on in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a 74°F (23°C)
temperature setting and allow about 20 minutes
for the system to regulate. Use the driver’s or
passenger’s temperature buttons to adjust thetemperature setting as necessary. If you choose
the temperature setting of 60°F (15°C), the system
will remain at the maximum cooling setting.
If you choose the temperature setting of 90°F (32°C),
the system will remain at the maximum heat setting.
Choosing either maximum setting will not cause
the vehicle to heat or cool any faster.
Be careful not to cover the sensor located on the top
of the instrument panel near the windshield. This sensor
regulates air temperature based on sun load and also
turns on your headlamps.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the engine coolant
temperature. Pressing the fan switch will override
this delay and change the fan to a selected speed.
O(Off):Press the driver’s side temperature knob to
turn off the climate control system. Outside air will
still enter the vehicle, and will be directed to the oor.
This direction can be changed by pressing the mode
button. The temperature can also be adjusted using
either temperature knob. Press the up or down arrows
on the fan switch, the defrost button, the AUTO
button, driver’s side temperature knob, or the air
conditioning button to turn the system on when it is off.
3-25

If you try to select recirculation in one of those modes,
the indicator will ash three times and turn off. The
air conditioning compressor will also come on when
this mode is activated. While in recirculation mode
the windows may fog when the weather is cold
and damp. To clear the fog, select either the blend
or defrost mode and increase the fan speed.
Recirculation mode can be turned off by pressing
the button again, or turning off the engine.
Air Conditioning
#
(Air Conditioning):Press this button to turn the
air conditioning (A/C) compressor on and off. When air
conditioning is selected, an indicator light will come on to
let you know that the air conditioning has been activated.
Pressing this button when the outside temperature is too
cool for air conditioning will make the air conditioning
indicator ash three times and then turn off indicating
the air conditioning mode is not available. If the air
conditioning is on and the outside temperature drops
below a temperature which is too cool for air conditioning
to be effective, the air conditioning light will turn off to let
you know the air conditioning mode has been canceled.
On hot days, open the windows long enough to let hot
inside air escape. This helps to reduce the time it takes
for your vehicle to cool down. It also helps the system
to operate more efficiently.The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount
of water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
If your vehicle has heated seats or heated and cooled
seats, seeHeated Seats on page 1-4orHeated
and Cooled Seats on page 1-5.
Defogging and Defrosting
Fog on the inside of the windows is a result of high
humidity (moisture) condensing on the cool window
glass. This can be minimized if the climate control
system is used properly. There are two modes to
clear fog or frost from your windshield. Use the defog
mode to clear the windows of fog or moisture and warm
the passengers. Use the defrost mode to remove fog
or frost from the windshield more quickly.
Use the mode up and down arrows to select the defog
or defrost modes.
-(Defog):This mode directs air to the windshield,
oor outlets, and side window vents. When you select
this mode, the system turns off recirculation and runs
the air conditioning compressor unless the outside
temperature is close to freezing. The recirculation mode
cannot be selected while in the defog mode. Do not
drive the vehicle until all the windows are clear.

The StabiliTrak®light will
ash on the instrument
panel cluster when the
system is both on and
activated.
You may also feel or hear the system working; this is
normal.
The traction control disable
button is located on the
instrument panel below the
climate controls.
The traction control part of StabiliTrak
®can be turned
off by pressing and releasing the StabiliTrak®button if
both systems (traction control and StabiliTrak®) were
previously on. To disable both traction control and
StabiliTrak
®, press and hold the button for ve seconds.Traction control and StabiliTrak
®can be turned on by
pressing and releasing the StabiliTrak®button if not
automatically shut off for any other reason.
When the TCS or StabiliTrak
®system is turned off, the
StabiliTrak®light and the appropriate TCS off or
StabiliTrak®off message will be displayed on the DIC to
warn the driver. Your vehicle will still have brake-traction
control when traction control is off, but will not be able to
use the engine speed management system. See
“Traction Control Operation” next for more information.
When the traction control system has been turned off,
you may still hear system noises as a result of the
brake-traction control coming on.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn the
system off if your vehicle is stuck in sand, mud, ice or
snow, and you want to “rock” your vehicle to attempt to
free it. It may also be necessary to turn off the system
when driving in extreme off-road conditions where high
wheel spin is required. SeeIf Your Vehicle is Stuck in
Sand, Mud, Ice, or Snow on page 4-33.

Uniform Tire Quality Grading
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
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-type
snow tires, space-saver, or temporary use
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.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specied
government test course. For example, a tire
graded 150 would wear one and a half (1.5) 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 signicantly from
the norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.
Traction – AA, A, B, C
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
specied 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.
