2006 CADILLAC XLR V sensor

Twilight Sentinel®
Twilight Sentinel®can turn your 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 you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take approximately one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure your
instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on page 3-33
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, your lamps
will remain on until:
The exterior lamp switch is moved from OFF to the
parking lamp position, or
a delay time that you select has elapsed.
SeeDriver Information Center (DIC) on page 3-64to
select the delay time that you want. You can also select
no delay time.
If you turn off the ignition 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.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Ultrasonic Rear Parking
Assist (URPA)
Ultrasonic Rear Parking Assist can help you to
determine how close an object is to your rear bumper
within a given area, making parking easier.
{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,
on the center console.
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 comes on, the
three lights on the display will illuminate to let you know
that the system is working. URPA senses how close your
vehicle is to an object. The distance is determined by the
four ultrasonic sensors located on the rear bumper.
3-38

When you shift into REVERSE (R) and an object is
detected, 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; and
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 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 dealer. For cleaning instructions, seeWashing
Your Vehicle on page 6-80.
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 air brakes 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.

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.
AUTO will appear on the display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70°F (21°C) and 80°F (27°C). An initial
setting of 73°F (23°C) is suggested.
Choosing the warmest or coldest temperature
setting will not cause the system to heat or cool
any faster. If you set the system at the warmest
or coldest temperature setting, the system will
remain in manual mode at that temperature and
it will not go into automatic mode.
In cold weather, the system will 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 3-64for more information.
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.
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.
Manual Operation
wPWRx(Power/Temperature):Press the PWR
button on the left side of the climate control panel to turn
the entire climate control system on or off. Press the
up or down arrow on the switch to manually increase or
decrease the temperature inside the vehicle.
3-42

((Heated/Cooled Seat):Press this button to turn the
feature on. The button on the left controls the driver’s
seat and the button on the right controls the passenger’s
seat. Each press of the button will take you to a
different setting. The settings available in order are
HI HEAT, LO HEAT, OFF, HI COOL, LO COOL
and OFF. You will be able to feel the temperature
change in a few minutes.
The feature will automatically turn off when the vehicle
is turned off.
?(Recirculation):Press this button to turn the
recirculation mode on or off. The air-conditioning
compressor also comes on. This mode keeps outside
air from coming 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 defrost or oor/defog
modes.
Using recirculation for long periods of time may cause
the air inside your vehicle to become too dry. To prevent
this from happening, after the air in your vehicle has
cooled, turn the recirculation mode off.
Sensors
There are sensors to measure the temperature and
sun’s effect on passenger comfort.
The solar sensor on your vehicle monitors the solar
radiation 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 solar sensor located on
the top of the instrument panel near the windshield
or the system will not work properly.
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.
3-44

If the outside temperature goes up, the display
temperature will not change until:
The vehicle’s speed is above 10 mph (16 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 you start the vehicle. 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 you block or cover it, the system will not function
properly.
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 or frost
from your windshield. Use the oor/defog mode to
clear the windows of fog or moisture and warm
the passengers. Use defrost to remove fog or frost from
the windshield more quickly.
-(Floor/Defog):Press the mode button until the
defog mode appears on the display. This mode directs
the air between the windshield, oor outlets and
side windows. When you select this mode, the system
turns off recirculation and runs the air-conditioning
compressor unless the outside temperature is near or
below freezing. The recirculation mode cannot be
selected while in the oor/defog mode.
1(Defrost):Press this button to direct most of the
air to the windshield, with some air directed to the side
windows. In this mode, the system will automatically
turn off the recirculation and run the air-conditioning
compressor, unless the outside temperature is near or
below freezing. Recirculation cannot be selected while in
the defrost mode. Do not drive the vehicle until all the
windows are clear.
3-45

NO FOB, OFF OR RUN?:When this message displays,
it means that the keyless access transmitter is not
detected inside the vehicle while you are trying to turn
the ignition off. Your vehicle may be near a strong
radio antenna signal causing the keyless access system
to be jammed. The vehicle will remain in ACC until off
or START has been pressed or ve minutes has
expired. If you turn the ignition off and you cannot nd
the keyless access transmitter, you will not be able
to restart the vehicle. The keyless access transmitter
needs to be inside of the vehicle in order for the vehicle
to start. SeeStarting the Engine on page 2-22for
more information.
OVER SPEED WARNING:This message is displayed
when the vehicle speed exceeds a certain limit as
required by some export countries. A chime will sound
when this message is displayed.
PRESS BRAKE TO START:The brake pedal must
be applied to start the vehicle. Make sure you are
pressing the brake pedal all the way down.
REDUCED ENGINE POWER:This message informs
you that the vehicle is reducing engine power because
the transmission is being placed in gear under conditions
that may cause damage to the vehicle’s engine,
transmission, or ability to accelerate. Reduced engine
power can affect the vehicle’s ability to accelerate. If this
message is on, but there is no reduction in performance,
proceed to your destination.The performance may be reduced the next time the
vehicle is driven. The vehicle may be driven at a reduced
speed while this message is on, but acceleration and
speed may be reduced. Anytime this message stays on,
the vehicle should be taken to your GM dealer for service
as soon as possible.
RIGHT DOOR AJAR:The passenger’s door is open or
ajar when this message appears. The vehicle must
be running and the transmission not in PARK (P) for this
message to display. A chime will sound if the vehicle’s
speed is greater than 3 mph (5 km/h).

SHIFT TO PARK:This message indicates that the
vehicle is not in PARK (P) when the engine is being
turned off. The vehicle will be in accessory mode. Once
the shifter is moved to PARK (P), the vehicle will turn off.
STABILITRAK ACTIVE:You may see the
STABILITRAK ACTIVE message on the DIC. It means
that an advanced, computer-controlled system has
come on to help your vehicle continue to go in
the direction in which you are steering. This stability
enhancement system activates when the computer
senses that your vehicle is just starting to spin, as it
might if you hit a patch of ice or other slippery spot
on the road. When the system is on, you may hear
a noise or feel a vibration in the brake pedal.
This is normal.
When the STABILITRAK ACTIVE message is on, you
should continue to steer in the direction you want to go.
The system is designed to help you in bad weather
or other difficult driving situations by making the
most of whatever road conditions will permit. If the
STABILITRAK ACTIVE message comes on, you will
know that something has caused your vehicle to start to
spin, so you should consider slowing down. A single
chime will also sound when this message is displayed.
STABILITRAK READY:If this message appears
and a chime sounds, the system has completed the
functional check of the StabiliTrak
®System.STABILITRAK WARMING:When you rst start your
vehicle and drive away, especially during cold winter
weather, the STABILITRAK WARMING message may
be displayed in the DIC along with a chime and the
traction control warning light. This is normal. You can
acknowledge this message by pressing the RESET
button. The StabiliTrak
®performance is affected until the
STABILITRAK READY message is displayed in the
DIC, which can take up to 15 minutes.
SVC (Service) TIRE MONITOR:If this message comes
on, a part on the Tire Pressure Monitor (TPM) is not
working properly. If you drive your vehicle while any of the
four sensors are missing or inoperable, the warning will
come on in approximately 10 minutes. If all four sensors
are missing, the warning will come on in approximately
15 to 20 minutes. All the sensors would be missing, for
example, if you put different wheels on your vehicle
without transferring the sensors. If the warning comes on
and stays on, there may be a problem with the TPM.
See your GM dealer.
TOOCOLDTOMOVETOP:This message will display
when the retractable hardtop button is pressed and the
hardtop pump motor temperature is below−4°F (−20°C).
Wait for the hardtop pump motor to warm up before using
the retractable hardtop.
