Interior Lamps
Your interior lamps
control is located next to
the exterior lamps
control and to the left of
the steering wheel on
the instrument panel.
9(Off):Turn the control to this position to
disable courtesy lamps, entry lighting, delayed
entry lighting, and delayed exit lighting.
1(Door):Turn the control to this position to turn
the interior lamps on when any door is open and
when the ignition key is removed from the ignition.
+(On):Turn the control to this position to turn
on the interior lamps.
The interior lamps can be controlled, or
automatically turned on or off under certain
conditions. They are explained in the following text.
Instrument Panel Brightness
The instrument panel lights can be brightened or
dimmed by pressing the center knob of the
interior lamp controls until it pops out. Turn the
knob clockwise to brighten the lights or
counterclockwise to dim them.
Courtesy Lamps
Courtesy lamps come on to make it easier to
enter and exit the vehicle. These lamps will come
on when the interior lamp control is in the door
position and any door is opened.
Entry Lighting
The courtesy lamps will come on and stay on for a
set time whenever the interior lamp control is in
the door position and the UNLOCK button on
the Remote Keyless Entry (RKE) transmitter is
pressed.
The lamps will stay on while a door is opened and
then turn off automatically about 25 seconds
after it is closed. If the UNLOCK button is pressed
and a door is not opened, the lamps will turn off
after about 25 seconds.
161

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.
25 seconds has passed.
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 Personalization on page 229under INT
(Interior) LIGHTS KEYS REMOVED. When
activated, this feature illuminates the interior for a
period of time after the ignition key is removed
from the ignition.
The ignition must be off and the interior lamp
control must be in the door position for delayed
exit lighting to work. When the ignition key is
removed, interior illumination will activate
and remain on until one of the following occurs:
The ignition is in RUN.
The power door locks are activated.
25 seconds has passed.
If during the illumination period a door is opened,
the timed illumination period will be canceled
and the interior lamps will remain on.

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:
The Ultrasonic Rear Park Assist (URPA)
system does not replace driver vision.
URPA does not:
Operate above speeds of
3 mph (5 km/h).
Detect objects more than 5 feet
(1.5 meters) behind the vehicle. This
distance may be less during warmer
or humid weather.
Detect objects that are below the
bumper, underneath the vehicle, or
that are very close to the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
CAUTION: (Continued)
CAUTION: (Continued)
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the URPA system,
always check carefully before backing up
by checking behind your vehicle.
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.
165

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.
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 yourtrunk. 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 442.
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.

This control has four types of operation.
Automatic can set/change the temperature
only. AUTO and temperature only will
appear on the display.
Semi-Automatic Fan can set/change the
temperature and mode. The fan operates
automatically. The temperature and mode will
appear on the display.
Semi-Automatic Mode can set/change the
temperature and fan speed. The mode

10. Install a new passenger compartment air lter.
SeeNormal Maintenance Replacement Parts
on page 471for the type of lter to use.
Make sure it slides under the compartment
retainers.
11. Reverse Steps 1 through 8.
For best climate control performance,
re-installation of a clean air lter is required.
Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages
that may be on the vehicle. The pictures will
help you locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to
cause an expensive repair or replacement. Paying
attention to the warning lights and gages could also
save you or others from injury.Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. As
you will see in the details on the next few pages,
some warning lights come on briey when you
start the engine just to let you know they are
working. If you are familiar with this section, you
should not be alarmed when this happens.
Gages can indicate when there may be or is a
problem with one of your vehicle’s functions. Often
gages and warning lights work together to let
you know when there is a problem with your
vehicle.
When one of the warning lights comes on and
stays on when you are driving, or when one of the
gages shows there may be a problem, check
the section that tells you what to do about
it. Please follow this manual’s advice. Waiting to
do repairs can be costly – and even dangerous. So
please get to know the warning lights and gages.
They are a big help.
179

SeePassenger Sensing System on page 75for
more on this, including important safety
information.
If, after several seconds, all 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.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 182.
Charging System Light
This light comes on
briey when the ignition
is turned on, as a
check to show that it is
working. Then it
should go out.
If it stays on, or comes on while the vehicle is being
driven, a chime will sound and there may be a
problem with the charging system. It could indicate
that the vehicle has a loose accessory belt or
another electrical problem. Have it checked right
away. Driving while this light is on could drain the
battery and result in the engine suddenly stopping.
If the vehicle must be driven a short distance with
the light on, be certain to turn off all unnecessary
electrical loads, such as the radio, heater fan,
air conditioning fan, and heated seats.
