2004 CADILLAC CTS warning

Charging System Light
When you turn the key to
ON or START, this light will
come on briey to show
that the generator and
battery charging systems
are working properly.
If this light stays on, your vehicle needs service. You
should take your vehicle to the dealer at once. To save
your battery until you get there, turn off all accessories.
For more information seeDIC Warnings and Messages
on page 3-70.
Brake System Warning Light
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 is a brake problem.
Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to ON. If it doesn’t come on then, have it
xed so it will be ready to warn you if there’s a problem.

When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake doesn’t
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
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
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
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.
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’s normal.
If the ABS warning light comes on and stays on, there
may be a problem with the anti-lock portion of the brake
system. If the red BRAKE light is not on, you
still have brakes, but you don’t have antilock brakes.
SeeBrake System Warning Light on page 3-43.
If the light stays on, turn the ignition to OFF. If the light
comes on when you’re 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’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. SeeBrake System Warning Light on
page 3-43.

Traction Control System (TCS)
Warning Light
If the TC (traction control)
warning light comes on
and stays on, there may be
a problem with the
traction control system.
The TC (traction control) warning light will come on
briey when you turn the ignition to ON. If it doesn’t
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 if you turn the traction control
system off using the TC (traction control) on/off button
located in the glove box for the CTS and on the steering
wheel for the CTS-V.
If the TC (traction control) warning light stays on or
comes on while you are driving, pull off the road as soon
as possible and stop carefully. Try resetting the system
by turning the ignition off then back on. If the light still
stays on or comes back on again while you are driving,
your vehicle needs service. Have the traction control
system inspected as soon as possible. SeeTraction
Control System (TCS) (CTS) on page 4-8orTraction
Control System (TCS) (CTS-V) on page 4-9for
more information.
Engine Coolant Temperature
Warning Light (CTS)
This light tells you that
your engine is very hot.
This light will come on when you rst start the vehicle
as a check to let you know that the light is working. It will
go out after a few seconds. If the light does not come
on, the bulb may be burned out. See your dealer
for assistance in changing the bulb.
If the light does not go out or if the light comes on and
stays on while you are driving, your vehicle may
have a problem with the cooling system. You should
stop the vehicle and turn off the engine as soon
as possible to avoid damage to the engine. A warning
chime will sound when this light is on, also.
SeeEngine Overheating on page 5-31and
Message Center (CTS-V) on page 3-53(CTS-V)
for more information.

Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature. If the gage
pointer moves into
the shaded area, the
engine is too hot.
That reading means the same thing as the warning
light – the engine coolant is very hot. SeeEngine
Overheating on page 5-31.
Tire Pressure Light (CTS-V)
This light will come on if
the system detects low
tire pressure.
This light will also come on for a bulb check when the
vehicle is started.
SeeTire Pressure Monitor System (CTS-V) on
page 5-70for more information.
For more information on the proper tire pressure,
seeLoading Your Vehicle on page 4-34. For more
information on your tires, seeTires on page 5-58. CTS shown,

Cruise Control Light
This light comes on
whenever you set your
cruise control.
The light will go out when the cruise control is
turned off. SeeCruise Control on page 3-23for
more information.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
See “Headlamp High/Low-Beam Changer” under
Turn Signal/Multifunction Lever on page 3-10for
more information.
Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It works
only when the ignition
is in ON.
If the fuel supply gets low, the Fuel Level Low message
will appear on the DIC and a single chime will sound.
SeeDIC Warnings and Messages on page 3-70
for more information.

Here are a few concerns some owners have had about
the fuel gage. All of these situations 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 full.
The gage may change when you turn, stop quickly
or accelerate quickly.
It takes a little more or less fuel to ll the tank than
the gage indicated. For example, the gage may
have indicated that the tank was half full, but
it actually took a little more or less than half the
tank’s capacity to ll the tank.
Message Center
Message Center (CTS-V)
The message center can display information relating to
powertrain uids, tire pressures, vehicle dynamics,
speedometer and odometer information, and
transmission status. It also displays warning messages.
There are two different areas where message center
information will be displayed. One display is inside of the
tachometer and the other is inside of the speedometer.These are the controls for
the message center.
They are located on
the left spoke of the
steering wheel.
The outboard switch controls the display of information
inside of the tachometer. The upper button on the
inboard switch controls the display of information inside
of the speedometer. The lower button on the inboard
switch turns the traction control on or off. SeeDriving at
Night on page 4-18for more information.

Oil Pressure
When the oil pressure is
displayed you will see the
oil pressure symbol.
The oil pressure will be displayed in psi or kPa and
there will be a graph at the bottom of the display. If the
graph shows the pressure in the shaded area all the
way to the left, then the oil pressure is low. SeeEngine
Oil on page 5-18for more information.
Oil Temperature
When the oil temperature
is displayed you will see
the oil temperature symbol.The temperature will be displayed in degrees Fahrenheit
or Celsius and there will be a graph at the bottom of
the display. If the graph shows the temperature in
the shaded area all the way on the right, then the oil
temperature is hot. SeeEngine Oil on page 5-18
for more information.
Transmission Temperature
When the transmission
temperature is displayed
you will see the
transmission
temperature symbol.
The temperature will be displayed in degrees Fahrenheit
or Celsius and there will be a graph at the bottom of
the display. If the graph shows the temperature in
the shaded area all the way on the right, then the
transmission temperature is hot. SeeDIC Warnings and
Messages on page 3-70andManual Transmission
Fluid on page 5-27for more information.
3-55

Tire Pressure
When the tire pressure is displayed you will see a
vehicle in the display. The numbers in each corner
represent the tire pressure for the corresponding tire.
The tire pressure will be displayed in psi or kPa.
If any of the tires are blinking on the vehicle in the
display, this means that the tire pressure in that tire is
either high or low. SeeTire Pressure Monitor System
(CTS-V) on page 5-70for more information.
Lateral Acceleration
Lateral acceleration is a measure of how hard you are
taking a corner. For example, when you are turning right
you will feel your body push to the left. This force is
measured in a “g”. This gage will display from 0.00 g to
1.2 g. The lowest reading means there is no lateral
acceleration. The highest reading means the force the
driver is feeling is 1.2 times the acceleration due
to gravity.
When the lower button on the outboard switch is
pressed and held while the Lateral Acceleration display
is being shown, the peak hold values—both tick
marks and numbers—will be reset to zero.
Warning Messages
The warning messages that are described in the
following text are also shown in the tachometer display.
While any warning messages are shown, pressing
either button on the outboard switch will acknowledge
the warning and then display the gage relating to
the error message. For instance, if a tire is below the
minimum recommended pressure, the tire pressure
warning message will blink on and off (5 times for a
low tire warning, continuously for a at tire warning).
The driver can go to the tire pressure display
immediately by pressing either button on the
outboard switch.
