CADILLAC CTS 2007 1.G Owners Manual

Engine Speed Limiter
This feature prevents the engine from operating at
too many revolutions per minute (rpm). When
the engine’s rpms are too high, the throttle
is closed to reduce speed. If this is not sufficient,
then the fuel supply to the engine will be
limited. When the rpms return to normal, the fuel
supply will return to normal. This helps prevent
damage to the engine.
Safety Belt Reminder Light
When the key is turned to ON or START, a chime
will come on for several seconds to remind
people to fasten their safety belts.
The safety belt light will
also come on and
stay on for several
seconds, then it will
ash for several more.
If the driver’s belt is already buckled, the chime
will not 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 70.
This light will come
on when the ignition
key is turned to ON
and it will ash for
a few seconds.
Then the light should go out. This means the
system is ready. If it does not go out, have your
vehicle serviced right away.
201

If the airbag readiness light stays on after you
start the vehicle or comes on while you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
{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 Driver Information Center (DIC)
display. SeeDIC Warnings and Messages on
page 232for more information.
Passenger Airbag Status Indicator
Your rearview mirror has a passenger airbag
status indicator.
When the ignition key is turned to ON or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check.
United States
Canada
202

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.
If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s frontal airbag is enabled
(may inate).
{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag. A
child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the right
front passenger’s frontal airbag if the
system detects a rear-facing child restraint,
no system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend that
rear-facing child restraints be secured in
the rear seat, even if the airbag is off.
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 82for more on this,
including important safety information.
203

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 201.
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 232.
204

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not 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 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 326.
{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),
the light will come
on when your engine is
started and stay on
for several seconds.
This is 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 brake system
warning light is not on, you still have brakes,
but you do not have anti-lock brakes. SeeBrake
System Warning Light on page 205for more
information.
If the light stays on, turn the ignition to OFF. 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. SeeBrake System Warning Light on
page 205for more information.
The ABS warning light should come on briey
when you turn the ignition key to 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.
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.
206

The TC warning light will come on briey when
you turn the ignition to ON. If it 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 if you turn the traction
control system off using the TC on/off button
located in the glove box for the CTS and on the
steering wheel for the CTS-V.
If the TC 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 (TCS)
inspected as soon as possible. SeeTraction
Control System (TCS) (CTS) on page 293
orTraction Control System (TCS) (CTS-V) on
page 295for more information.Engine Coolant Temperature
Warning Light (CTS)
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, see your dealer.
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 also sound when this
light is on.
SeeEngine Overheating on page 360for more
information.
207

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 360.
Tire Pressure Light (CTS-V Only)
If the vehicle has the
Tire Pressure Monitor
System, 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 on page 405
for more information.
For more information on the proper tire pressure,
seeLoading Your Vehicle on page 321. For
more information on your tires, seeTires on
page 392.
208

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 332.
209

This light should come on, as a check to show
you it is working, when the ignition is on and the
engine is not running. 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.
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 you are towing a trailer, reduce the amount
of cargo being hauled as soon as it is
possibleIf 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 key 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 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 337.
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.
