2008 CADILLAC XLR fuses

Arming the System
To arm the system:
Press the lock button on the keyless access
transmitter.
Open the door. Lock the door with the power
door lock switch. The security light should
ash. Remove the keyless access transmitter
from the interior of the vehicle and close the door.
The security light will stop ashing and stay on.
After 30 seconds, the light should turn off.
The vehicle can be programmed to automatically
lock the doors and arm the system when you
exit the vehicle. SeeDIC Vehicle Personalization
on page 3-76.
Now, if a door or the trunk lid is opened without the
keyless access transmitter, the alarm will go off. Your
horn will sound for two minutes, then it will go off to save
battery power. And, your vehicle will not start without
a keyless transmitter present.
The theft-deterrent system will not arm if you lock the
driver’s door with the power door lock switch after
the doors are closed.
If your passenger stays in the vehicle when you leave
with the keyless access transmitter, have the passenger
lock the vehicle after the doors are closed. This way the
alarm will not arm, and your passenger will not set it off.
Testing the Alarm
To test the system:
1. Make sure the trunk lid is latched.
2. Lower the window on the driver’s door.
3. Manually arm the system.
4. Close the doors and wait 30 seconds.
5. Reach through the open window and manually
pull the release lever on the oor.
6. Turn off the alarm by pressing the unlock button
on the transmitter.
If the alarm is inoperative, check to see if the horn
works. If not, check the horn fuse. SeeFuses and
Circuit Breakers on page 6-90. If the horn works, but
the alarm doesn’t go off, see your dealer/retailer.
Disarming the System
Always use your keyless access transmitter to unlock
a door either by pressing the unlock button on the
transmitter or by squeezing the door handle sensor while
you have the transmitter with you. Unlocking a door any
other way will set off the alarm. If your alarm sounds,
press the unlock button on the keyless access transmitter
to disarm it.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Immobilizer Operation
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition
mode transitions to OFF.
The immobilization system is disarmed when the ignition
mode transitions to ACCESSORY or START and a
valid transmitter is found in the vehicle.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
The system has one or more keyless access
transmitters that are matched to an immobilizer control
unit in your vehicle. Only a correctly matched keyless
access transmitter will start the vehicle. If the keyless
access transmitter is ever damaged, you may not
be able to start your vehicle.
When trying to start the vehicle, if the engine does
not start and the security light comes on, there may
be a problem with your immobilizer system. Press the
START button again.If the vehicle does not start and the keyless access
transmitter appears to be undamaged, try another
keyless access transmitter. Or, you may try placing the
transmitter in the transmitter pocket. See “NO FOBS
DETECTED” underDIC Warnings and Messages
on page 3-63for additional information. At this time,
you may also want to check the fuse. SeeFuses
and Circuit Breakers on page 6-90. If the engine
still does not start with the other transmitter, your
vehicle needs service. If the engine does start, the
rst transmitter may be faulty. See your dealer/retailer
who can service the theft-deterrent system and
have a new keyless access transmitter programmed
to the vehicle.
It is possible for the immobilizer system to learn new or
replacement keyless access transmitters. Up to 4 keyless
access transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 2-6.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
GTurn and Lane-Change Signals. SeeTurn
and Lane-Change Signals on page 3-8.
3Headlamp High/Low-Beam Changer. See
Headlamp High/Low-Beam Changer on page 3-9.
-Fog Lamps. SeeFog Lamps on page 3-30.
Flash-to-Pass Feature. SeeFlash-to-Pass on
page 3-9.
ICruise Control. SeeCruise Control on
page 3-12.
PExterior Lamps Control. SeeExterior Lamps
on page 3-28.
Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the multifunction lever all the
way up or down. When the turn is nished, the lever will
return automatically.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
If you signal a turn or a lane change and the arrows
ash faster than normal, a signal bulb may be burned
out. Other drivers will not see the turn signal.
Replace burned-out bulbs to help avoid possible
accidents. If the arrows do not go on at all when you
signal a turn, check the fuses and check for burned-out
bulbs. SeeFuses and Circuit Breakers on page 6-90.

To adjust the HUD so you can see it properly, do the
following:
1. Adjust the seat to a comfortable driving position.
If you change your seat position later, you may
have to re-adjust your HUD.
2. Start your engine and press the top or bottom of the
HUD button to center the HUD image in your view.
The HUD image can only be adjusted up and down,
not side-to-side.
3. Press the DIMMER button until the DIC reads HUD
DIMMING. Then use the brightness button to adjust
the desired intensity.
The brightness of the HUD image is determined by the
light conditions in the direction your vehicle is facing
and where you have the HUD set. If you are facing a
dark object or a heavily shaded area, your HUD
may anticipate that you are entering a dark area and
may begin to dim.
To turn off the HUD, press the brightness button down
until the image disappears.
Polarized sunglasses could make the HUD image
harder to see.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 6-90.
Keep in mind that your windshield is part of the HUD
system. SeeWindshield Replacement on page 6-50.

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 3-8for 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 3-8for more information.Accessory Power Outlet(s)
The accessory power outlet can be used to connect
electrical equipment such as a cellular phone or
CB radio.
The accessory power outlet is located inside the
center console storage compartment, on the forward
left side.
To use the outlet, remove the tethered cap. When not
using it, always cover the outlet with the protective cap.
Notice:When using an accessory power outlet,
maximum electrical load must not exceed 20 amps.
Always turn off any electrical equipment when
not in use. Leaving electrical equipment on for
extended periods will drain your vehicle’s battery.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on accessory power outlets.

Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker. If the wiper motor overheats due to
heavy snow, the wipers will stop until the motor cools
and will then restart.
A fuse powers the wiper motor. If the fuse blows, there
is an electrical problem. Be sure to have it xed.
Power Windows and Other Power
Options
Circuit breakers in the fuse block protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is xed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of res
caused by electrical problems.Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without — like the radio or
cigarette lighter — and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
Instrument Panel Fuse Block
The panel fuse block is located on the passenger side
of the vehicle, under the instrument panel and under the
toe-board.
Remove the carpet and toe-board covering to access
the fuse block by pulling at the top of each corner
of the panel. Then turn the fuse block door knob
counterclockwise and pull the door to access the fuses.
