2011 CADILLAC DTS Owners Manual

Black plate (55,1)Cadillac DTS Owner Manual - 2011
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 6‑3.
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 6‑8. 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 6‑5.
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.
4-56

Black plate (57,1)Cadillac DTS Owner Manual - 2011
.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
{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.
This light comes on briefly while starting the engine.
If it does not, have the vehicle serviced by your dealer.
If the system is working normally the indicator light then
goes off.
If the light comes on and stays on, it means that oil is
not flowing through the engine properly. The vehicle
could be low on oil and it might have some other
system problem.

Fuel Gauge
The fuel gauge shows
approximately how much
fuel is in the 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 in the Driver Information Center
and a single chime sounds. See DIC Warnings and
Messages
on page 4‑65for more information.
Here are a few situations that may occur with the fuel
gauge. All of these 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 the vehicle is
turning, stops quickly or accelerates 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 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 the odometer
on the left side. The bottom line of the DIC display also
shows a digital speedometer on the right side.
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.

(Trip/Fuel): The following display menu items can
be displayed by pressing the trip/fuel button:
TRIP A or TRIP B
These displays show the current distance traveled
since the last reset for each trip odometer in either
kilometers (km) or miles (mi). Both odometers can be
used at the same time. Each trip odometer can be reset
to zero separately by pressing and holding the set/reset
button for a few seconds while the desired trip odometer
is displayed.
FUEL RANGE
This display shows the approximate number of
remaining kilometers (km) or miles (mi) you can drive
without refilling the fuel tank. This estimate is based on
the current driving conditions and will change if the
driving conditions change. For example, if you are
driving in traffic and making frequent stops, the display
may read one number, but if you enter the freeway, the
number may change even though you still have the
same amount of fuel in the fuel tank. This is because
different driving conditions produce different fuel
economies. Generally, freeway driving produces better
fuel economy than city driving.
