2007 CADILLAC XLR V Owners Manual

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. SeeTowing Your
Vehicle on page 359.
{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.
Anti-Lock Brake System Warning
Light
With the Anti-Lock
Brake System (ABS),
this 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 “Service ABS” underDIC
Warnings and Messages on page 206.
The ABS warning light will come on briey 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.
193

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.
194

If you turn off the StabiliTrak®system, by pressing
the front part of the button on the console for
ve seconds, the TCS light will come on, a chime
will sound and the TRAC/STABILITRAK OFF
message will be displayed in the DIC. The TCS
will also be turned off. SeeDIC Warnings and
Messages on page 206for more information.
If the StabiliTrak
®system and TCS 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.
SeeDIC Warnings and Messages on page 206for
more information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
As the pointer nears 260°F (125°C), 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 206
for more information.

Tire Pressure Light
This light will come on
briey when you turn
the ignition on.
This light will also come on when one or more of
your tires are signicantly underinated.
A LOW TIRE PRESS DIC message will
accompany the light, seeOther Messages on
page 219for more information.Stop and check your tires as soon as it is safe to do
so. If underinated, inate to the proper pressure.
SeeTires on page 413for more information.
This light will ash for about 60 seconds and then
turn on solid if a problem is detected with the
Tire Pressure Monitor system.
SeeTire Pressure Monitor System on page 423
for more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition,
and emission control
systems.
196

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.
Notice:If you keep driving your vehicle with
this light on, after awhile, 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:Modications 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 sameTire Performance Criteria (TPC) can affect your
vehicle’s emission controls and may cause
this light to come on. Modications 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. SeeAccessories
and Modifications on page 363.
This light should come on briey, 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 Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. Diagnosis and service may be
required.
197

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 “If the Light Is On Steady” 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 “If the Light Is
On Steady” following. If the light is still ashing,
follow the previous steps, and see your dealer for
service as soon as possible.
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. SeeFilling the Tank on page 369.
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 vehicle’s 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.
198

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 366. Poor fuel
quality will cause the 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, misring, 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.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is in
the passenger compartment. SeeIgnition Positions
on page 88. Press the bottom of the Acc. button on
the instrument panel and hold the button down for
ve seconds. The instrument panel, including the
check engine light, will light up and the ignition will
be on, but the engine will not start — if you press
the bottom of the Acc. button only briey, less than
ve seconds, the accessory power mode will be
turned on, but not the ignition. After the bulb check,
be sure to press and release the Acc. button again
to turn the ignition off and avoid draining the
vehicle’s battery.
199

Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if you have recently replaced the
battery or if the battery has run down. The
diagnostic system is designed to evaluate critical
emission control systems during normal driving.
This may take several days of routine driving.
If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, your dealer can prepare the vehicle for
inspection.Engine Oil Pressure Gage
The engine oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) or kPa
(kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi
(140 to 550 kPa). In certain situations such as
long, extended idles on hot days, it could read as
low as 6 psi (40 kPa) and still be considered
normal. It may vary with engine speed, outside
temperature and oil viscosity. The Driver
Information Center (DIC) may display messages
regarding the oil condition. SeeDIC Warnings and
Messages on page 206andEngine Oil on
page 377.
