Ultrasonic Rear Parking Assist
(URPA)
The Ultrasonic Rear Parking Assist (URPA) system is
designed to help you park while the vehicle is in
REVERSE (R). It operates only at very low speeds, less
than 3 mph (5 km/h). URPA can help make parking
easier and help you avoid colliding with objects such as
parked vehicles. The URPA system can detect objects
up to 5 feet (1.5 m) behind the vehicle, and tell you how
close these objects are from your rear bumper.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
parking. And, the system does not detect
objects that are more than 5 feet (1.5 meters)
behind the vehicle.
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using rear park assist,
always check carefully behind your vehicle
before you back up and then watch closely as
you do.

The URPA display is
located inside the vehicle,
above the rear window.
It has three color-coded
lights that can be seen
through the rearview mirror
or by turning around.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system turns on, the
three lights on the display will illuminate for one and
a half seconds to let you know that the system is
working. If your vehicle is moving in REVERSE (R) at
a speed greater than 3 mph (5 km/h), the red light
will ash to remind you that the system does not work
at a speed greater than 3 mph (5 km/h).If an object is detected at a REVERSE (R) speed of
less than 3 mph (5 km/h), one of the following will occur:
Description English Metric
Amber light 5 ft 1.5 m
Amber/amber lights 40 in 1.0 m
Amber/amber/red lights &
continuous chime20 in 0.5 m
Amber/amber/red lights
ashing & continuous
chime1 ft 0.3 m
A chime will sound the rst time an object is detected
between 20 inches (0.5 m) and 5 feet (1.5 m) away.
URPA cannot detect objects that are above trunk level.
In order for the rear sensors to recognize an object,
it must be within detection range behind the vehicle.
When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R), if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush. Other conditions that may affect
system performance include things like the vibrations
from a jackhammer or the compression of air brakes on a
very large truck. If after cleaning the rear bumper and
then driving forward at least 15 mph (25 km/h), the
display continues to ash red, see your dealer.
3-48

Page 183 of 446

If a trailer was attached to your vehicle, or a bicycle or
an object was hanging out of your trunk during your
last drive cycle, the light may also ash red. The light will
continue to ash whenever in REVERSE (R) until
your vehicle is driven forward at least 15 mph (25 km/h)
without any obstructions behind the vehicle.
For cleaning instructions, seeWashing Your Vehicle on
page 5-89.
Accessory Power Outlets
Your vehicle is equipped with accessory power outlets.
The outlets can be used to plug in electrical equipment
such as a cellular telephone, CB radio, etc.
Your vehicle has one outlet in front of the center
console, one in the center console lid and there may be
an additional outlet in the rear of the center console.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet. If it
does, when not using the outlet be sure to cover it with
the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.Certain accessory power plugs may not be compatible
to the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information on
the accessory power outlets.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating. Check
with your dealer before adding electrical equipment.
Follow the proper installation instructions that are
included with any electrical equipment you install.
Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
Ashtrays and Cigarette Lighter
Your vehicle may have an ashtray and cigarette lighter.
Notice:If you put papers, pins, or other ammable
items in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
your vehicle. Never put ammable items in the
ashtray.

Ashtray
The ashtray is located under the climate control panel
on the center console. Press on the door to release the
ashtray.
To empty the ashtray, remove it from the center
console by gripping the edges and pulling straight out.
To reinstall, push the tray back into place.
There may also be ashtrays in the rear doors.
Cigarette Lighter
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
The cigarette lighter is located next to the ashtray.
The vehicle does not have any cigarette lighters for
the rear seat passengers.
Press the lighter all the way in and release it. It will
pop back out by itself once the element has heated
for use.
Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode, the
air conditioning compressor, and the fan speed.Vehicles With Heated and Ventilated Seats Shown,
Vehicles Without Similar
3-50

Page 185 of 446

AUTO will appear on the display next to the fan, mode
indicators, and recirculation indicator if your vehicle
is equipped with the optional air quality sensor.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting,
generally, between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest
temperature setting, the system will try to
continuously heat the vehicle and will not adjust the
system down as the vehicle warms up.
In cold weather, the system may start at reduced
fan speeds to avoid blowing cold air into your
vehicle until warmer air is available. The system will
start out blowing air at the oor but may change
modes, automatically, as the vehicle warms
up to maintain the chosen temperature setting. The
length of time needed for warm up will depend
on the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Controls
and Displays on page 3-74.The air-conditioning system removes moisture from the
air, so you may notice water dripping underneath
your vehicle while idling or after turning off the engine.
This is normal.
Manual Operation
yNz(Mode):Pressing the mode switch and
changing the mode cancels automatic operation and
allows the operator to manually select the air delivery
location. Press AUTO to return to automatic operation.
The outboard air outlets will always receive airow
regardless of the mode selected. SeeOutlet Adjustment
on page 3-56to change this airow from the outboard
outlets.
To change the current mode, select one of the following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets. In
automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets, and a little air directed to the windshield and
side windows.
3-51

Page 186 of 446

The mode switch can also be used to select the defog
mode. Information on defogging and defrosting can
be found later in this section.
yAz(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and allows the operator to manually
select the amount of airow. Press AUTO to return to
automatic operation.
If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-58and
Scheduled Maintenance on page 6-4.
h(Recirculation):This button controls the air
source for the climate control system. If you are in
AUTO mode, pressing this button once will choose
recirculation. This mode keeps outside air from coming
in the vehicle and recirculates the air in the vehicle.
It can be used to prevent outside air and odors
from entering your vehicle or to help cool the air inside
your vehicle more quickly.
Recirculation is not available in the defrost mode and
will shut off when defog mode is selected. Both of these
features are designed to limit fogging in your vehicle.
If recirculation is selected during defog mode, it will
automatically turn off after 10 minutes to limit problems
with fogging.In some conditions, using recirculation for long periods
of time may cause the air inside your vehicle to
become too dry or stuffy. To prevent this from
happening, after the air in your vehicle has cooled,
select AUTO to return to automatic climate control
operation or push the recirculation button again to select
outside air.
Pressing this button a second time selects outside air.
:(Outside Air):This mode forces the system
to pull air from outside the vehicle. It can be used to
bring fresh air into the vehicle.
Air Quality Sensor:Your vehicle may be equipped
with an optional air quality sensor to help limit the
climate control system from pulling in some harmful
exhaust fumes from older, poorly running or
diesel-equipped vehicles that are driving near you.
This sensor, when active, will monitor the air quality in
front of your vehicle and switch to air recirculation when
poor quality air is detected outside your vehicle. You
can activate the air quality sensor on your vehicle
(if equipped) by pressing the AUTO button on your
climate control. The word AUTO will be shown in
the center of the climate control display under the
outline shape of a vehicle. When the air quality sensor
senses poor quality air, the recirculation graphic will
be shown as long as the sensor senses poor quality air.
3-52

Page 187 of 446

Under some conditions, the air quality sensor system
will not operate. In cold weather, the system may not be
active (even if the AUTO indication is displayed)
because of concerns of fogging your windows, which
may occur by activating recirculation mode. Also, the air
quality sensor system will not remain in recirculation
mode for extended periods of time that could cause
stuffy or very dry conditions in the vehicle. Following a
poorly running vehicle for an extended period of
time may not keep recirculation active indenitely.
The air quality sensor will not activate due to organic
odors, like skunk, and may not activate on many
chemical-related odors. If you wish to limit these types
of odors, you may choose to manually select
recirculation. Your vehicle may also be equipped with
a charcoal lter that can limit many odors from
being pulled into your vehicle. This lter, like your
engines air cleaner lter, will need to be changed
periodically. SeeScheduled Maintenance on page 6-4.
The air quality sensor system does not protect
against carbon monoxide (CO), which you cannot see
or smell. SeeEngine Exhaust on page 2-33.
O(Power Driver’s Temperature):Press the power
button located on the driver’s side of the climate control
panel to turn the entire climate control system on or
off. Turn the knob to increase or decrease the
temperature inside your vehicle.
O(Power Passenger’s Temperature):Press the
power button located on the passenger’s side of
the climate control panel to turn the passenger’s climate
control system on if they wish to have a different
setting than the driver. Turn the knob to increase or
decrease the temperature for the front passenger.
Turning the passenger’s side power button off will not
shut off the climate control system for the passenger.
The system will be set to the same setting as the driver.
{(Ventilated Seat):Press this button (if equipped)
to turn on the ventilated seat for the driver’s or
passenger’s side. SeeHeated and Ventilated Seats
on page 1-4.
J(Heated Seat):Press this button (if equipped) to
turn on the heated seat and seatback for the driver’s or
passenger’s side. SeeHeated and Ventilated Seats
on page 1-4.
^(Air Conditioning):Press this button to manually
turn off the air conditioning compressor. Press AUTO
to return to automatic operation or press the A/C
OFF button again. To limit fogging on the windshield,
the air conditioning compressor cannot be in off in

Sensors
There is a solar sensor located on the instrument panel,
near the windshield.There is also an interior
temperature sensor
located next to the
steering wheel on the
instrument panel.
These sensors monitor the solar radiation and the air
inside your vehicle, then use the information to maintain
the selected temperature by initiating needed
adjustments to the temperature, the fan speed and the
air delivery system. The system may also supply
cooler air to the side of the vehicle facing the sun.
The recirculation mode may also be activated, as
necessary. Do not cover the sensors or the automatic
climate control system will not work properly.
3-54

Defogging and Defrosting
Fog on the inside of 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 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.
yNz(Mode):Press this button until defog appears
on the display.
-(Defog):This mode directs the air between the
windshield and oor outlets with some air supplied to the
outboard panel outlets and side window defogging
outlets. When you select this mode, the system turns off
recirculation and runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
The recirculation mode is cancelled when you enter
defog mode. If you select recirculation while in defog
mode, it will be cancelled after 10 minutes.
If you have fogging on the side windows, remain in
defog or defrost mode until they clear.
0(Defrost):Pressing the defrost button directs most
of the air to the windshield, with some air directed to
the side windows and outboard panel outlets. In
this mode, the system will automatically turn off
recirculation and run the air-conditioning compressor,
unless the outside temperature is at or below freezing.
Recirculation cannot be selected while in the
defrost mode.
This mode may also cause the fan speed and air
temperature to increase.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in ON or during remote start, if programmed.
See “Personal Settings Menu” underVehicle
Personalization on page 2-47for additional information.
=(Rear Window Defogger):Press this button to
turn the rear window defogger on or off. Be sure to clear
as much snow from the rear window as possible.
3-55

Page 190 of 446

The rear window defogger will turn off about 10 minutes
after the button is pressed, or if the vehicle’s speed
is above 30 mph (48 km/h), the rear defogger will stay
on continuously. If turned on again, the defogger
will only run for about ve minutes before turning off.
The defogger can also be turned off by pressing
the button again or by turning off the engine.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when
the rear window defogger button is on.
Notice:Using a razor blade or sharp object to
clear the inside rear window may damage the rear
window defogger. Repairs would not be covered
by your warranty. Do not clear the inside of the rear
window with sharp objects.
Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the airow.Turn the thumbwheel to the right to open the outlets
completely and allow the maximum amount of air
to enter your vehicle. Turn the thumbwheel to the left to
close the outlets and minimize the amount of air
entering the vehicle.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-58.
