How the System Works
URPA comes on automatically when the shift lever is
moved into R (Reverse). The rear display briey
illuminates to indicate the system is working.
URPA operates only at speeds less than 3 mph (5 km/h).
If the vehicle is above this speed, the red light on the rear
display will ash.
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below trunk level. Objects
must also be within 5 feet (1.5 m) from the rear bumper.
This distance may be less during warmer or humid
weather.
A single beep will sound the rst time an object is
detected between 20 inches (0.5 m) and 5 feet (1.5 m)
away. Beeping will occur when the vehicle is closer
than 20 inches (0.5 m) from the object.
The following describes what will occur with the URPA
display as the vehicle gets closer to a detected object:

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, a red light will be shown on the rear URPA
display when the shift lever is moved into R (Reverse).
This occurs under the following conditions:
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 6-77.
An object was hanging out of the trunk during the
last drive cycle. Once the object is removed,
URPA will return to normal operation.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled after driving forward at
least 15 mph (25 km/h), take the vehicle to your
dealer/retailer.

Move the lever to the following positions:
1(High Speed):For steady wiping at high speed.
6(Low Speed):For steady wiping at low speed.
&(Delay):Use to set a delay between wipes.
x(Delay Adjustment):Use for a delayed wiping
cycle. Turn the intermittent adjust band down for
a longer delay or up for a shorter delay. The wiper
speed can only be manually adjusted when the lever
is in this position.
9(Off):Turns off the windshield wipers.
8(Mist):Move all the way down to mist and release
for a single wiping cycle. The windshield wipers will
stop after one wipe. Hold the band on mist longer for
more wipes.
Heavy snow or ice can overload the wipers. If this occurs,
a circuit breaker will stop the wipers until the motor cools.
Clear all ice and snow from the windshield wiper blades
before using them. If the wiper blades are frozen to the
windshield, carefully loosen them or warm the windshield
before turning the wipers on. If they become worn or
damaged, get new blades or blade inserts.
Rainsense™ Wipers
With Rainsense wipers, there is a moisture sensor
mounted on the interior side of the windshield below
the rearview mirror, and it automatically operates the
wipers by monitoring the amount of moisture build-up
on the windshield. Wipes occur as needed to clear the
windshield depending on driving conditions and the
sensitivity setting. In light rain or snow, fewer wipes will
occur. In heavy rain or snow, wipes will occur more
frequently. The Rainsense wipers operate in a delay
mode as well as a continuous low or high speed as
needed. If the system is left on for long periods of time,
occasional wipes may occur without any moisture on
the windshield. This is normal and indicates that the
Rainsense system is activated.
The Rainsense system is also sensitive to vibration.
The system may activate if something hits the
windshield or if the vehicle hits a bump.
The Rainsense system can be activated by moving the
wiper lever up to the delay position and turning the
delay adjust band to one of the ve sensitivity levels.
The bottom delay adjust position is the lowest sensitivity
setting, level one. This allows more rain or snow to
collect on the windshield between wipes. Turning the
delay adjust band away from you to the higher sensitivity
levels allows less rain or snow to collect on the
windshield between wipes.
3-9

The top position is the highest sensitivity setting, level
ve. A single wipe will occur each time the delay adjust
band is turned to a higher sensitivity level to indicate
that the sensitivity level has been increased.
Notice:Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.
The mist and wash cycles operate as normal and are
not affected by the Rainsense function. The Rainsense
system can be overridden at any time by manually
changing the wiper control to low or high speed.
When Rainsense is active, the headlamps will turn
on automatically. If it is dark, they will remain on.
See “Wiper-Activated Headlamps” underExterior
Lamps on page 3-26for more information.
Notice:Do not place stickers or other items on
the exterior glass surface directly in front of
the moisture sensor. Doing this could cause the
moisture sensor to malfunction.Windshield Washer
K(Washer Fluid):The lever on the right side of the
steering column also controls the windshield washer.
There is a button at the end of the lever. To spray
washer uid on the windshield, press the button and
hold it. The washer will spray until you release the
button. The wipers will continue to clear the window
for about six seconds after the button is released and
then stop or return to your preset speed.
{CAUTION:
In freezing weather, do not use your washer until
the windshield is warmed. Otherwise the washer
uid can form ice on the windshield, blocking your
vision.
If the uid in the windshield washer uid reservoir is
low, the message LOW WASHER FLUID will appear
on the Driver Information Center (DIC) display. It
will take 60 seconds after the bottle is relled for this
message to turn off. For information on the correct
washer uid mixture to use, seeWindshield Washer
Fluid on page 6-31andRecommended Fluids and
Lubricants on page 7-11.

Twilight Sentinel®
This feature can turn the lamps on and off for you.
A light sensor on top of the instrument panel makes the
Twilight Sentinel
®work, so be sure it is not covered.
With Twilight Sentinel
®you will see the following happen:
When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps that
come on with headlamps will also come on.
When it is bright enough outside, the headlamps will
go off, and the front turn signal lamps (DRL) will
come on, as long as the exterior lamp switch is in the
AUTO position.
If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once the
vehicle leaves the garage, it takes about one minute for
the automatic headlamp system to change to DRL if
it is light outside. During that delay, the instrument panel
cluster may not be as bright as usual. Make sure the
instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on page 3-30
for more information.You can idle the vehicle with the lamps off, even when
it is dark outside. After starting the vehicle, turn the
exterior lamp control band to off, then release it.
The lamps will remain off until you turn the control
band to off again.
Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, the
lamps will remain on until:
The exterior lamp switch is moved from OFF to the
parking lamp position, or
the delay time selected has elapsed.
SeeDriver Information Center (DIC) on page 3-57to
select the delay time. You can also select no delay time.
If the ignition is turned off with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
The regular headlamp system should be turned on
when needed.

You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Operation
and Displays on page 3-57for more information.
The air conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine.
This is normal.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.

clear fog or frost from the surface of the mirrors
when the rear window defogger is on.
The rear window defogger and heated mirrors are
automatically disabled when the retractable hardtop
is moving or down.Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs would not be
covered by the vehicle warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.((Heated/Cooled Seat):Press to turn the feature on.
It automatically turns off when the vehicle is turned
off. SeeHeated and Cooled Seats on page 1-3for
more information.
Sensors
There are several sensors on the vehicle that measure
the temperature and the sun’s effect on passenger
comfort.
The solar sensor is located on top of the instrument panel
near the windshield. It monitors the solar heat then uses
the information to maintain the selected temperature
when operating in AUTO mode 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 will also be activated, as necessary. Do not cover
the sensor or the system will not work properly.
3-39

There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps maintain the temperature inside the vehicle.
The outside temperature will be displayed in the
navigation system only when the engine is running.
Any cover on the front of the vehicle could give a false
reading of the temperature.
If the outside temperature goes up, the display
temperature will not change until:
The vehicle’s speed is above 15 mph (24 km/h)
for ve minutes.
The vehicle’s speed is above 32 mph (51 km/h)
for two and one-half minutes.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when the vehicle is started. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
There is also an inside temperature sensor located to
the left of the ignition button. The automatic climate
control system uses this sensor to receive information,
so if it is blocked or covered, the system will not
function properly.
Outlet Adjustment
Use the thumbwheel to open or close the outlets.
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 the vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of the
vehicle more effectively.

Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime comes on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light also
comes on and stay on for
several seconds, then
it ashes for several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s
safety belt is already buckled, neither the chime nor the
light comes on.
Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the
airbag modules, the wiring and the crash sensing
and diagnostic module. For more information on the
airbag system, seeAirbag System on page 1-38.The airbag readiness light
ashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
xed immediately.
{CAUTION:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inate in a crash, or they could even inate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also come
on. SeeDIC Warnings and Messages on page 3-60
for more information.
