2007 CADILLAC STS ignition

Passenger Safety Belt
Reminder Light
Several seconds after the ignition button is
pressed to START, a chime will sound for several
seconds to remind the front passenger to
buckle their safety belt. This would only occur if
the passenger airbag is enabled. SeePassenger
Sensing System on page 74for more information.
The passenger safety belt light will also come
on and stay on for several seconds, then it
will ash for several more.
This chime and light will
be repeated if the
passenger remains
unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical
system for malfunctions. The light tells you if there
is an electrical problem. The system check
includes the airbag sensors, the airbag modules,
the wiring and the diagnostic module. For
more information on the airbag system, seeAirbag
System on page 64.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.

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 engine on. If it does not come on then, have it
xed so it will be ready to warn you if there is 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 does not 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 355.
{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 ABS warning light comes on and stays on,
there may be a problem with the antilock portion of
the brake system. If the brake system warning
light is not on, you still have brakes, but you do not
have antilock brakes. SeeBrake System Warning
Light on page 248for more information.
If the light stays on, press the ignition Acc. button.
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 systemwarning light is also on, you do not have anti-lock
brakes and there is a problem with your regular
brakes. SeeBrake System Warning Light on
page 248for more information.
The ABS warning light should come on briey
when you turn the ignition on. If the light does not
come on then, have it xed so it will be ready
to warn you if there is a problem.
Low Tire Pressure Warning Light
This light will come on
briey as you start the
engine, for vehicles
equipped with the
Tire Pressure
Monitor System.
This light will also come on when one or more of
your tires are signicantly underinated.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has 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.Notice:If you keep driving your vehicle with
this light on, after awhile, the emission controls
might not work as well, your vehicle’s fuel
economy might not be as good, and the engine
might not run as smoothly. This could lead
to costly repairs that might 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 same
Tire Performance Criteria (TPC) can affect
your vehicle’s emission controls and can cause
this light to come on. Modications to these
systems could lead to costly repairs not
covered by your warranty. This could also
result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 363.

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.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 365. 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 111. 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.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. The DIC
is also used to display warning/status messages.
All messages will appear in the DIC display located
at the bottom of the instrument panel cluster, below
the tachometer and speedometer. The DIC buttons
are located on the instrument panel, to the left of
the steering wheel.
The DIC comes on when the ignition is on. After a
short delay, the DIC will display the current
driver and the information that was last displayed
before the engine was turned off.
The top line of the DIC display shows the vehicle
system information and the warning/status
messages. The bottom line of the DIC display
shows either the odometer, the trip odometer A or
the trip odometer B information on the left side.
Only one odometer can appear at a time. See “Trip
Information” underDIC Controls and Displays
on page 258for information on changing the
display to show the odometer or trip odometer
information. The bottom line of the DIC display
also shows the outside temperature on the
right side and the shift lever position indicator inthe center. SeeAutomatic Transmission Operation
on page 116for more information on the shift
lever positions.
When the sport mode is active, an S will appear
next to the shift position indicator on the center of
the DIC display. When the manual mode is
active, an M will appear on the DIC display. When
the normal mode is active, only the shift position
indicator will appear. While the Driver Shift
Control (DSC) feature is active, the DIC will
change to show the selected gear. See “Driver
Shift Control (DSC)” underAutomatic Transmission
Operation on page 116for more information.
If a problem is detected, a warning message will
appear on the display. Be sure to take any
message that appears on the display seriously and
remember that clearing the message will only make
the message disappear, not correct the problem.
DIC Controls and Displays
The Driver Information Center (DIC) has different
modes which can be accessed by pressing
the four DIC buttons located on the instrument
panel, to the left of the steering wheel.
