Entry lighting includes a feature called theater dimming.
With theater dimming, the lamps do not turn off at
the end of the delay time. Instead, they slowly dim after
the delay time and then turn off.
The courtesy lamps turn off when the ignition key is
turned to RUN or START. They will come on again when
a door is opened.
Delayed Entry Lighting
Delayed entry lighting lights the vehicle’s interior for a
period of time after all the doors have been closed.
After all the doors have been closed, the delayed entry
lighting feature will continue to work until one of the
following occurs:
The ignition is in run.
The doors are locked.
Twenty-ve seconds has elapsed.
If during the illumination period a door is opened, the
timed illumination period will be canceled and the interior
lamps will remain on.
Theater Dimming
This feature allows for a three to ve-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
This feature can be programmed either on or off using
the Driver Information Center. SeeDIC Vehicle

visor vanity lamps, if equipped, are accidently left on. If
any of these lamps are left on while the ignition is
off, they will automatically turn off after 10 minutes. The
lamps will not come back on again until one of the
following occurs:
The ignition is turned on.
The interior lamps control is turned off, then to
door or on.
Ultrasonic Rear Parking
Assist (URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help you
park while in REVERSE (R) and operates only at speeds
less than 3 mph (5 km/h). URPA can help you avoid
colliding with objects such as parked vehicles. The
system can detect objects 5 feet (1.5 m) behind your
vehicle and tell you how close those objects are to your
rear bumper.
3-18

Page 133 of 410

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.
{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.
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R). When the system comes on,
the three lights on the display will briey illuminate 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 the
system does not work at this speed.
The rst time an object is detected while in
REVERSE (R), a chime will sound and the following will
occur in sequence, depending on the distance from
the object:
At 5 feet (1.5 m) a chime will sound and one amber
light will be lit.
At 40 inches (1.0 m) both amber lights will be lit.
At 20 inches (0.5 m) a continuous chime will sound
and all three lights (amber/amber/red) will be lit.
At 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will ash.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the
rear sensors to recognize an object, it must be within
operating range.
3-19

Page 134 of 410

If the URPA system is not functioning properly, the
display will ash red, indicating that there is a problem.
The light will also ash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or hanging out of your trunk. The light will
continue to ash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h).
It may also ash red if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper free of
mud, dirt, snow, ice and slush or materials such as
paint or the system may not work properly. If after
cleaning the rear bumper and driving forward at least
15 mph (25 km/h), the display continues to ash red, see
your GM dealer. For cleaning instructions, seeWashing
Your Vehicle on page 5-81.
It may also ash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h).
Other conditions that may affect system performance
include things like the vibrations from a jackhammer or
the compression of airbrakes on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.Accessory Power Outlets
The accessory power outlets enable power electrical
equipment such as a cellular telephone or a CB radio to
be used inside the vehicle.
Your vehicle is equipped with 12-volt outlets. One outlet
is located on the center console below the climate
controls. There may be another outlet located inside the
center storage console or in the ip and fold console.
Open the cover to use the outlet. Be sure to close
the cover when the outlet is not in use.
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. Check with your
dealer before adding electrical equipment.
Certain power accessory plugs may not be compatible
to the power accessory outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer.
3-20

Page 135 of 410

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.
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.
When adding electrical equipment, be sure to follow
the proper installation instructions included with
the equipment.Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation

climate control system off.
3-21

Page 136 of 410

9(Fan):Turn the knob by this symbol, located on the
left side of the climate control panel, clockwise or
counterclockwise to increase or decrease the fan speed.
During the highest fan speed selections, the fan
speed will be temporarily reduced between the transition
to a new mode. The fan will resume the original
speed when the transition to the new mode is complete.
Temperature Control:Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside your vehicle.
Use the right knob to select from the following modes:
H(Vent):This mode directs outside air to the
instrument panel outlets. If driving in city traffic, and the
vehicle is stopped and idling, or the weather is hot,
switch from this mode to the recirculation mode.
To prevent the air inside the vehicle from becoming
stale, be sure to return to the vent mode periodically.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and the remaining air to
the oor outlets. Some air may be directed toward the
windshield. Slightly cooler air is directed to the
instrument panel outlets and warmer air is directed to
the oor outlets.
6(Floor):This mode directs most of the air to the
oor outlets with some air directed toward the side
window outlets and a little air directed to the windshield.
In this mode, the system will automatically use outside
air. The air conditioning compressor will be engaged
unless the outside temperature is 40°F (4°C) or below.
Recirculation cannot be selected when in this mode.
You can also select modes by using the
following buttons:
h(Recirculate):Press this button to recirculate
cabin air through the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or
to help heat or cool the air inside your vehicle more
quickly. An indicator light below the button will come on
in this mode. Operation in this mode during periods
of high humidity and cool outside temperatures
may result in increased window fogging. If window
fogging is experienced, select the defrost mode.

#(Air Conditioning):Press this button to turn the air
conditioning system on or off. When this button is
pressed, an indicator light below the button will come on
to let you know the air conditioning is activated. Air
conditioning can be selected in any mode as long as the
fan switch is on.
On hot days during the vehicle’s initial start-up, open
the windows to let hot inside air escape; then close
them. This helps to reduce the time it takes for
the vehicle to cool down. It also helps the system to
operate more efficiently.
For quicker cool down on hot days, do the following:
1. Select the vent/outside air mode.
2. Select the recirculation mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
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.Defogging and Defrosting
Fog on the inside of the vehicle is a result of high
humidity causing moisture to condense on the cool
window glass. This can be minimized if the climate
control system is used properly. There are two modes
to clear frost or fog from the windshield. Use the
defog mode to clear the windows of condensation and
to warm the vehicle’s occupants. Use the defrost
mode to remove frost or condensation from the
windshield quickly. Recirculation cannot be selected
when in these modes.
See “Rear Window Defogger” later in this section for
information on clearing the rear window of fog or ice.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and the side window outlets and half to the
oor outlets.
0(Defrost):This mode directs most of the air to the
windshield and the side window outlets, with some
air directed to the oor outlets.
