2004 CADILLAC XLR ignition

Fog Lamps
If your vehicle has fog lamps, use them for better vision
in foggy or misty conditions.
The fog lamps control is located on the multifunction
lever next to the exterior lamp control.
-(Fog Lamps):Turning the band to this position will
turn on the fog lamps.
When you turn on the fog lamps, the fog lamp light on
the instrument panel cluster will come on to indicate that
the fog lamps and the parking lamps are on.
If you turn on the high-beam headlamps, the fog lamps
will turn off. They will turn back on again when you
switch to low-beam headlamps.
The ignition must be on for the fog lamps to operate.
Twilight Sentinelž
Twilight Sentinelžcan turn your lamps on and off for
you. A light sensor on top of the instrument panel makes
the Twilight Sentinel
žwork, so be sure it is not
covered.With Twilight Sentinel
žyou 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 OFF 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. See ªInstrument
Panel Brightness Controlº under
Interior Lamps on
page 3-25.
You can idle the vehicle with the lamps off, even when
it is dark outside. First set the parking brake while
the ignition is in OFF. Then start the vehicle. The lamps
will stay off until you release the parking brake.

Twilight Sentinelžalso provides exterior illumination as
you leave the vehicle. If Twilight Sentinelžhas 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.
See
Driver Information Center (DIC) on page 3-55to
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
ždelay 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.
Exterior Lighting Battery Saver
If the manual parking lamps or headlamps have been
left on, the exterior lamps will turn off as soon as
the ignition is turned off or RAP is active. This protects
against draining the battery in case you have
accidentally left the headlamps or parking lamps on.
The battery saver does not work if the headlamps are
turned on after the ignition switch is turned to OFF.
If you need to leave the lamps on, use the exterior lamp
control to turn the lamps back on.

Your vehicle has a feature to help prevent you from
draining the battery in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console
or glove box lamps are accidentally left on or in case
something is plugged into the accessory power outlet or
cigarette lighter. If you leave any of these lamps on,
they will automatically time-out after about 20 minutes.
To reset it, all of the above lamps must be turned
off or the ignition key must be in ON.

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 5-85
.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD
or your HUD image may look blurred and out of focus.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 ªAdaptive Cruise Control (ACC)º under
Turn
Signal/Multifunction Lever on page 3-5for more
information.
You may also see an ACC active symbol, alert symbol
or vehicle ahead symbol. See ªAdaptive Cruise
Control (ACC)º under
Turn Signal/Multifunction Lever on
page 3-5for more information.
3-29

?(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 mode.
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 right side of the instrument panel near the
windshield or 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.
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.

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That is
normal.
If the light stays on, turn the ignition off. Or, if the light
comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on,
or comes on again while you are driving, your vehicle
needs service. If the regular brake system warning light
is not on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
ªService ABSº under
DIC Warnings and Messages
on page 3-57.
The anti-lock brake system warning light will come on
brie¯y when you turn the ignition on. This is normal.
If the light does not come on then, have it ®xed so it will
be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
This light should come on
brie¯y 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
žsystem
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 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 system light will come on and the
TRACTION SYSTEM-OFF message will show on
the DIC.

Tire Pressure Light
This light should come on
brie¯y as you start the
engine. It will then come on
only when a low tire
pressure condition exists.
See
Tire Pressure Monitor System on page 5-58for
more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
3-48

Fuel Gage
Your fuel gage tells you
about how much fuel you
have left when the
ignition is on.
When the needle approaches the low fuel symbol, LOW
FUEL will appear on the Driver Information Center (DIC)
display. At this time, you still have a little fuel left, but
you should get more soon.
Press RESET to acknowledge a DIC message(s).
Pressing RESET will also turn off a DIC message but
the LOW FUEL message will come on again in
10 minutes if you have not added fuel to the vehicle.Here are ®ve things that some owners ask about. All
these things are normal and do not indicate that
anything is wrong with the fuel gage.·At the gas station, the gas pump shuts off before
the gage reads the full symbol.
·It takes more (or less) fuel to ®ll up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank's
capacity to ®t it.
·The gage pointer may move while cornering,
braking or speeding up.
·The gage may not indicate the tank is empty when
the ignition is turned off.
·The gage reading may change slightly within the
®rst several minutes after starting the vehicle.
