2004 CADILLAC XLR Owners Manual

Air Bag Off Light
When you turn the passenger's air bags off, this light
will come on and stay on to remind you that the air bags
have been turned off. This light will go off when you
turn the air bags back on. See
Air Bag Off Switch
on page 1-44for more on this, including important safety
information.
{CAUTION:
If the passenger's air bags are turned off for a
person who is not in a risk group identi®ed by
the national government, that person will not
have the extra protection of the air bags. In a
crash, the air bags would not be able to in¯ate
and help protect the person sitting there. Do
not turn off the passenger's air bags unless
the person sitting there is in a risk group. See
Air Bag Off Switch on page 1-44for more on
this, including important safety information.
3-43

{CAUTION:
If the air bag readiness light ever comes on
when you have turned off the air bags, it
means that something may be wrong with the
air bag system. The passenger's air bags
could in¯ate even though the switch is off. If
this ever happens, do not let anyone whom the
national government has identi®ed as a
member of a passenger air bag risk group sit
in the passenger's position (for example, do
not secure a rear-facing child restraint in your
vehicle) until you have your vehicle serviced.
See
Air Bag Off Switch on page 1-44.
Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of your
battery. When the engine
is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, your instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when your vehicle is at 10 volts or below. Have
it checked right away. Driving with the voltmeter reading
at 10 volts or below could drain your battery and
disable your vehicle.

Brake System Warning Light
Your vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
This light should come on when you start the engine. If
it does not come on then, have it ®xed so it will be
ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer to
Parking Brake on page 2-26to see if it is set. If the parking brake is not set, have
your brake system inspected right away.If the light comes on while you are driving and you have
a LOW BRAKE FLUID message showing on the DIC,
pull off the road and stop carefully. You may notice that
the pedal is harder to push. Or, the pedal may go
closer to the ¯oor. It may take longer to stop. If the light
is still on, have the vehicle towed for service. See
Towing Your Vehicle on page 4-32.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed for
service. United States

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.
3-46

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
žand the vehicle needs service.
You can acknowledge this message by pressing the
RESET button. When the SERVICE STABILITRAK
message is displayed, the Stabilitrak
žsystem 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.
If you turn off the Stabilitrak
žsystem by pressing the
button on the console, the traction control system
light will come on, a chime will sound and the
TRAC/STABILITRAK OFF message will be displayed in
the DIC. The Traction Control System will also be
turned off. See
DIC Warnings and Messages on
page 3-57for more information.
If the Stabilitrak
žsystem and Traction Control System
are turned off, pressing the console button momentarily
will turn both systems on. The DIC will display the
TRAC/STABILITRAK ON message, the instrument
cluster light will be off and a chime will sound. See
DIC
Warnings and Messages on page 3-57for more
information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
As the pointer nears 260ÉF (125ÉC), your engine coolant
temperature is high. A message may display on the
Driver Information Center (DIC) depending on how high
the temperature is. See
DIC Warnings and Messages
on page 3-57for more information.

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

Notice:If you keep driving your vehicle with this
light on, after a while, your emission controls
may not work as well, your fuel economy may not
be as good and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
Notice:Modi®cations made to the engine,
transmission, exhaust, intake or fuel system of your
vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle's emission
controls and may cause this light to come on.
Modi®cations to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
This light should come on brie¯y, as a check to show
you it is working, as you start the engine. If the light
does not come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
·Light FlashingÐ A mis®re condition has
been detected. A mis®re increases vehicle
emissions and may damage the emission control
system on your vehicle. Diagnosis and service may
be required.
·Light On SteadyÐ An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
·Reducing vehicle speed.
·Avoiding hard accelerations.
·Avoiding steep uphill grades.
If the light stops ¯ashing and remains on steady, see ªIf
the Light Is On Steadyº following.
If the light continues to ¯ash, when it is safe to do so,
stop the vehicle.Find a safe place to park your vehicle.
Turn the engine off, wait at least 10 seconds and
restart the engine. If the light remains on steady, see ªIf
the Light Is On Steadyº following. If the light is still
¯ashing, follow the previous steps, and see your dealer
for service as soon as possible.
3-49

If the Light Is On Steady
You also may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See
Filling Your Tank on page 5-7. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-5. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, mis®ring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to ®x any
mechanical or electrical problems that may have
developed.
