2007 CADILLAC XLR display

As light shines out from the HUD, it is possible for
light to shine back in. In rare occurrences,
when the sun is at a specic angle and position,
the sun’s rays can shine back into the HUD. When
this occurs, the display device within the HUD
will be temporarily illuminated. The event will end
when the vehicle’s angle to the sun changes.
Clean the inside of the windshield as needed to
remove any dirt or lm that reduces the sharpness
or clarity of the HUD image.
To clean the HUD, spray household glass cleaner
on a soft, clean cloth. Wipe the HUD lens gently,
then dry it. Do not spray cleaner directly on the lens
because the cleaner could leak into the unit.
If the ignition is on and you cannot see the HUD
image, check to see if:
Something is covering the HUD unit.
The brightness is adjusted properly.
The HUD image is adjusted to the proper
height.
Ambient light in the direction your vehicle is
facing is low.
A fuse is blown. SeeFuses and Circuit
Breakers on page 453.Keep in mind that your windshield is part of the
HUD system. SeeWindshield Replacement
on page 412.
The following Adaptive Cruise Control (ACC)
messages may appear in the HUD:
CRUISE SPEED LIMITED:This message
indicates that your vehicle speed has been
reduced below your set speed due to ACC
limitations. Your set speed is too high and ACC
cannot detect other vehicles at far enough
distances for the system to operate properly.
TIGHT CURVE:This message indicates that ACC
has reduced your vehicle speed due to a tight
curve in the road. Once the road straightens, ACC
will return to your selected set speed or follow
distance setting. See “Adaptive Cruise Control
(ACC)” underTurn Signal/Multifunction Lever on
page 141for more information.
You may also see an ACC active symbol, alert
symbol or vehicle ahead symbol. See “Adaptive
Cruise Control (ACC)” underTurn
Signal/Multifunction Lever on page 141for more
information.

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:
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.
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.
175

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. 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 trunklevel. 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 446.
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.

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 asthe 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). See
DIC Controls and Displays on page 204for
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.
179

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 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.
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. Do not
drive the vehicle until all the windows are clear.
182

Speedometer and Odometer
Your speedometer lets you see your speed in
either miles per hour (mph) or kilometers per
hour (km/h).
There is only one scale for mph and km/h. Use
the Driver Information Center (DIC) controls
to switch between mph and km/h. SeeDIC
Controls and Displays on page 204for more
information. The cluster will calculate the proper
speed and move the needle to the correct position.
Either the MPH or the km/h telltale will illuminate,
depending on which measurement you choose.
The odometer is part of the Driver Information
Center (DIC). SeeDIC Controls and Displays on
page 204for more information.
Trip Odometer
The trip odometer is part of the Driver Information
Center (DIC). SeeDIC Controls and Displays
on page 204for more information.
Tachometer
The tachometer displays the engine speed in
thousands of revolutions per minute (rpm).
Fuel will shut off at about 6700 rpm.If you continue to drive your vehicle at the fuel
shut off rpm, you could damage your engine. Be
sure to operate your vehicle below the fuel
shut off rpm or reduce your rpm quickly when the
fuel shuts off.
Safety Belt Reminder Light
When the ignition button is pressed to START, a
chime will be provided for several seconds to
remind people to buckle their safety belts. The
driver safety belt light will also be provided and stay
on for several seconds, then it will ash for several
more. You should buckle your seat belt.
This chime and light will
be repeated if the driver
remains unbuckled
and the vehicle
is in motion.
If the driver’s belt is buckled, neither the chime nor
the light will be provided.
187

If the word OFF or the off symbol is lit on the
passenger airbag status indicator, it means that
the passenger sensing system has turned off
the passenger’s airbags. SeePassenger Sensing
System on page 53for 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 airbag 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 airbag. SeeAirbag
Readiness Light on page 188.
Charging System Light
When you turn the
engine on, this light will
come on briey to
show that the generator
and battery charging
systems are working
properly.
If this light stays on, your vehicle needs service.
You should take your vehicle to the dealer at once.
To save your battery until you get there, turn off
all accessories. SeeDIC Controls and Displays on
page 204for more information.
191

Traction Control System (TCS)
Warning Light
This light should come
on briey as you start
the engine.
If the light does not come on then, have it xed so
it will be ready to warn you if there is a problem.
The light will also come on while the StabiliTrak
®
system warms up and the STABILITRAK
WARMING message will be displayed in the
Driver Information Center (DIC).
If it stays on, or comes on and the DIC shows a
SERVICE TRACTION SYS message when you are
driving, there is a problem with your Traction
Control System (TCS) and your vehicle needs
service. When this light is on, the system will not
limit wheel spin. Adjust your driving accordingly.If the driver turns off TCS by pressing the button
on the console, the TCS light will come on and the
TRACTION SYSTEM OFF message will show
on the DIC.
If the light stays on or comes on while you are
driving, a chime sounds and a SERVICE
STABILITRAK message appears on the DIC,
there is a problem with your StabiliTrak
®and the
vehicle needs service.
You can acknowledge this message by pressing
the RESET button. When the SERVICE
STABILITRAK message is displayed, the
StabiliTrak
®system will not assist you in
controlling the vehicle. You should have the
system serviced as soon as possible. Adjust your
driving accordingly.
When the system is working, you will see the
STABILITRAK ACTIVE message displayed in the
DIC. You may also feel of hear the system
working. This is normal.
