2007 CADILLAC STS light

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.
244

{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
If there is a problem with the airbag system in
your vehicle, the SERVICE AIR BAG message will
appear on the DIC display. SeeDIC Warnings
and Messages on page 264for more information.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your overhead console has a passenger airbag
status indicator.
The indicator next to the passenger airbag status
indicator lights is the passenger safety belt
reminder light. SeePassenger Safety Belt
Reminder Light on page 244for more information
on that indicator.
When the vehicle is running, the passenger airbag
status indicator will light ON and OFF, or the
symbol for on and off, for several seconds as a
system check. Then, after several more seconds,
the status indicator will light either ON or OFF, or
either the on or off symbol, to let you know the
status of the right front passenger’s frontal airbag.

245

If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 74for more on this,
including important safety information.
If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 244.

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

Engine Coolant Temperature
Warning Light
The engine coolant
temperature warning
light will come on when
the engine is very hot.
This light will also come on briey when the
vehicle is started.
If the light does not go out or comes on and stays
on while driving, there may be a problem with
the cooling system. Driving with engine coolant
temperature light on could cause your vehicle

Operating Mode on page 395. SeeEngine
Overheating on page 393andDIC Warnings and
Messages on page 264for more information.
Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
It can be used to see when your engine has
warmed up and to make sure your cooling system
is operating properly. If the gage pointer moves

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.
