Readings in the low warning zone may occur when
a large number of electrical accessories are operating
in the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading
in either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
With the ignition on, the brake system warning light
will flash when you set the parking brake. The light
will flash if the parking brake doesn't release fully.
If you try to drive with the parking brake engaged,
a chime will sound when the vehicle speed is greater
than 3 mph (5 km/h).Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
United States Canada
This light should come on briefly when you turn the
ignition key to RUN. If it doesn't come on then, have it
fixed so it will be ready to warn you if there's a problem.
2-73
If the light comes on while you are driving, 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 floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. See ªTowing Your Vehicleº in
the Index.
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've
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, this light will come
on when you start your
engine and may stay
on for several seconds.
That's normal.
If the light stays on, or comes on when you're driving,
your vehicle needs service. If the regular brake system
warning light isn't on, you still have brakes, but you
don't have anti
-lock brakes. If the regular brake system
warning light is also on, you don't have anti
-lock brakes
and there's a problem with your regular brakes. See
ªBrake System Warning Lightº earlier in this section.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN.
If the light doesn't come on then, have it fixed so
it will be ready to warn you if there is a problem.
2-77
The TRAC OFF light may come on for the
following reasons:
If you turn the system off by pressing the TCS on/off
button located to the right of the steering wheel, the
light will come on and stay on. To turn the system
back on, press the button again; the light should
go off.
If you move the shift lever to FIRST (1), the light
will come on and stay on to indicate that the Traction
Control System is off. This is normal operation.
To turn the system back on, move the shift lever
back to a position other than FIRST (1); the light
should go off. See ªTraction Control Systemº in
the Index.
The light will come on and stay on if the TCS
automatic engagement feature has been turned off.
To turn the system on, press the TCS off/on button;
the light should go off. To turn the automatic
engagement feature back on, see ªTraction Control
Systemº in the Index.
If the Traction Control System is affected by an
anti
-lock brake system, Traction Control System or
engine
-related problem, the system will turn off and
the light will come on. Have your vehicle serviced.If the vehicle is driven over an extremely rough road,
the system will turn off and the light will come on.
The light will go off a few seconds after the rough
road conditions go away or when the vehicle comes
to a complete stop. This is normal operation.
Malfunction Indicator Lamp (Service
Engine Soon Light in the United States
or Check Engine Light in Canada)
United States Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
2-91 STABILITY SYSTEM DISABLED Message
The STABILITY SYSTEM
DISABLED message
indicates that the stability
enhancement system has
been temporarily disabled.
There are three conditions that can cause this message
to appear. One condition is overheating, which could
occur if the stability enhancement system activates
continuously for an extended period of time. The
STABILITY SYSTEM DISABLED message will
also be displayed if the brake system warning light is
on. See ªBrake System Warning Lightº in the Index.
Finally, the message could be displayed if the stability
system takes longer than usual to complete its diagnostic
checks due to driving conditions. The STABILITY
SYSTEM DISABLED message will turn off as soon as
the conditions that caused the message to be displayed
are no longer present.
Secondary Information Center (SIC)
This section explains the features of your SIC. The SIC
provides instant information about fuel, mileage and
vehicle history in addition to allowing you to personalize
certain features of your vehicle. If you would like to skip
to the section on personalizing your vehicle, see the
section under MENU.
Fuel
Each press of the FUEL button will change the
display between the fuel remaining range, average
fuel economy, instantaneous fuel economy and a
blank display.
The average fuel economy can be reset using the
RESET button.

A chime will sound the first time an object is detected.
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 the center of the Cadillac crest
badge. 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 flash red, indicating that there is a problem.
The light will also flash red while driving if a trailer or
trailer hitch ball mount is attached to your vehicle or if a
bicycle or object is on the back of, or hanging out of
your vehicle. The light will continue to flash until the
trailer or the object is removed and your vehicle is
driven forward at least 15 mph (25 km/h).
It may also flash 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 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 flash red, see your dealer. It may also flash
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.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being sure to
check for other vehicles, obstructions and blind spots.
For cleaning instructions, see ªCleaning Your Vehicleº
in the Index.

Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti
-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on. This is normal.
If there's a problem with the
anti
-lock brake system, this
warning light will stay on.
See ªAnti
-Lock Brake
System Warning Lightº in
the Index.
4-9
Remember: Anti-lock doesn't change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you won't have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti
-lock brakes.
Using Anti
-Lock
Don't pump the brakes. Just hold the brake pedal down
firmly and let anti
-lock work for you. You may feel the
brakes vibrate, or you may notice some noise, but this
is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control System (TCS)
(2
-Wheel Drive)
Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the rear wheels are spinning or
beginning to lose traction. When this happens, the
system reduces engine power to limit wheel spin.
This light will come on
when the TCS is limiting
wheel spin. See ªLow
Traction Lightº in the
Index. You may hear or
feel the system working or
notice a lack of accelerator
response, but this is normal.
The Traction Control System may operate on dry roads
under some conditions. When this happens, you may
notice a reduction in acceleration. This is normal and
doesn't mean there's a problem with your vehicle.
Examples of these conditions include a hard acceleration
in a turn, an abrupt upshift or downshift of the
transmission or driving on rough roads.
4-10
If your vehicle is in cruise control when the TCS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may re
-engage the cruise control.
See ªCruise Controlº in the Index.
When the TRAC OFF
light is on, the TCS is
off and will not limit
wheel spin. Adjust your
driving accordingly.
The TRAC OFF light will come on under the
following conditions:
The Traction Control System is turned off, either by
pressing the TCS on/off button or turning off the
automatic engagement feature of the TCS.
The transmission is in FIRST (1); TCS will not
operate in this gear. This is normal.The vehicle is driven on an extremely rough road.
When the vehicle leaves the rough surface, slows
down or stops, the light will go off and TCS will be
on again. This is normal.
A Traction Control System, Anti
-Lock Brake
System or engine
-related problem has been detected
and the vehicle needs service.
See ªTraction Off Lightº in the Index.
The Traction Control System, as delivered from the
factory, will automatically come on whenever you start
your vehicle. To limit wheel spin, especially in slippery
road conditions, you should always leave the system on.
But you can turn the TCS off if you ever need to.
You should turn the TCS off if your vehicle ever gets
stuck in sand, mud or snow and rocking the vehicle is
required. See ªRocking Your Vehicleº in the Index.
To turn the system on or
off press the TCS on/off
button located to the right
of the steering wheel,
on the instrument panel.
