2011 CADILLAC STS Owners Manual

Black plate (63,1)Cadillac STS Owner Manual - 2011
This light should come on
when the ignition is on,
but the engine is not
running, as a check to
show it is working. If it
does not, have the vehicle
serviced by your dealer.
If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light can
prevent more serious damage to the vehicle. This
system assists the service technician in correctly
diagnosing any malfunction.
Notice: If the vehicle is continually driven with this
light on, after a while, the emission controls might
not work as well, the vehicle 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 the vehicle warranty. Notice:
Modifications made to the engine,
transmission, exhaust, intake, or fuel system of the
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle's emission
controls and can cause this light to come on.
Modifications to these systems could lead to costly
repairs not covered by the vehicle warranty. This
could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6‑4.
This light comes on during a malfunction in one of
two ways:
Light Flashing: A misfire condition has been detected.
A misfire increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the amount of cargo
being hauled as soon as it is possible.

If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the vehicle off, wait at least 10 seconds, and
restart the engine. If the light is still flashing, follow
the previous steps and see your dealer for service
as soon as possible.
Light On Steady:An emission control system
malfunction has been detected on the vehicle.
Diagnosis and service might be required.
An emission system malfunction might be corrected by
doing the following:
.Make sure the fuel cap is fully installed. See Filling
the Tankon page 6‑9. The diagnostic system
can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should
turn the light off.
.If the vehicle has been driven through a deep
puddle of water, the vehicle's electrical system
might be wet. The condition is usually corrected
when the electrical system dries out. A few driving
trips should turn the light off.
.Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run as
efficiently as designed and can cause: stalling
after start-up, stalling when the vehicle is changed
into gear, misfiring, hesitation on acceleration,
or stumbling on acceleration. These conditions
might go away once the engine is warmed up.
If one or more of these conditions occurs, change
the fuel brand used. It will require at least one full
tank of the proper fuel to turn the light off.
See Gasoline Octane on page 6‑7.
If none of the above have made the light turn off,
your dealer can check the vehicle. The dealer has the
proper test equipment and diagnostic tools to fix any
mechanical or electrical problems that might have
developed.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments may have
programs to inspect the on-vehicle emission control
equipment For the inspection, the emission system test
equipment is connected to the vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument panel to the left of the
steering wheel. See your dealer if assistance is needed.The vehicle may not pass inspection if:
.the Malfunction Indicator Lamp is on with the
engine running, or if the light does not come on
when the ignition is turned to ON/RUN while the
engine is off.
.the critical emission control systems have not been
completely diagnosed by the system. This can
happen if the battery has recently been replaced or
if the battery has run down. The diagnostic system
evaluates critical emission control systems during
normal driving. This can take several days of
routine driving. If this has been done and the
vehicle still does not pass the inspection, your
dealer can prepare the vehicle for inspection.

Oil Pressure Light
For vehicles with an oil
pressure light, if there is a
problem with the oil, the
light may stay on after
the engine is started,
or comes on while driving.
This light indicates that oil is not going through the
engine quickly enough to keep it lubricated. The engine
could be low on oil or could have some other oil
problem. Have the vehicle serviced by your dealer.
The oil light could also come on in the following
situations:
.The light comes on briefly when the ignition is
turned on to show that it is working properly. If it
does not come on with the ignition on, there may
be a problem with the fuse or bulb. Have the
vehicle serviced by your dealer.
.Sometimes when the engine is idling at a stop, a
chime sounds and the light may blink on and off.
This is normal.
{WARNING:
Do not keep driving if the oil pressure is low. The
engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice: Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule for changing engine oil.

Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
See Headlamp High/Low-Beam Changer
on page 4‑5for more information.
Fuel Gauge
The fuel gauge shows
approximately how much
fuel is in the fuel tank.
It works only when the
engine is on. An arrow on the fuel gauge indicates the side of the
vehicle the fuel door is on.
If the fuel supply gets low, the
“FUEL LEVEL LOW”
message appears on the Driver Information Center
(DIC) and a single chime sounds. See DIC Warnings
and Messages
on page 4‑76for more information.
All of the following situations are normal and do not
indicate that anything is wrong with the fuel gauge:
.At the gas station the gas pump shuts off before
the gauge reads full.
.The gauge may change when you turn, stop
quickly or accelerate quickly.
.It takes a little more or less fuel to fill the tank than
the gauge indicated. For example, the gauge 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 fill the tank.

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
Operation and Displays
on page 4‑70for 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 in the
center. See
Automatic Transmission Operation
on
page 3‑30for 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 3‑30for 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.
