Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Adaptive Cruise Control (ACC) is an enhancement to
traditional cruise control. It allows you to keep cruise
control engaged in moderate traffic conditions without
having to constantly reset your cruise control. ACC
uses radar to detect a vehicle directly ahead in your
path, within a distance of 100 m (330 ft), and operates
at speeds above 40 km/h (25 mph). When it is engaged
by the driver, the system can apply limited braking or
acceleration of the vehicle automatically to maintain a
selected follow distance to the vehicle ahead. Braking is
limited to 2.45 m/sec2 (0.25 g's) of deceleration, which is
comparable to moderate application of the vehicle's
brakes. To disengage ACC, apply the brake. If no
vehicle is in your path, the vehicle will react like
traditional cruise control.
{WARNING:
Adaptive Cruise Control will not apply hard
braking or bring the vehicle to a complete
stop. It will not respond to stopped vehicles,
pedestrians or animals. When you are
approaching a vehicle or object, Adaptive Cruise
Control may not have time to slow your vehicle
enough to avoid a collision. Your complete
attention is always required while driving and you
should be ready to take action and apply the
brakes. For more information, seeDefensive
Driving on page 5‑2.

ACC may detect a vehicle that is not in your lane and
apply the brakes.
ACC may, occasionally, provide a driver alert and/or
braking that you consider unnecessary. It could respond
to signs, guardrails, and other stationary objects when
entering or exiting a curve. This is normal operation.
Your vehicle does not need service.
Highway Exit Ramps
{WARNING:
Adaptive Cruise Control may lose track of the
vehicle ahead and accelerate up to your set
speed while entering or on highway exit ramps.
You could be startled by this acceleration and
even lose control of the vehicle. Disengage
Adaptive Cruise Control before entering a
highway exit ramp. Do not use Adaptive Cruise
Control while entering or on exit ramps.
Other Vehicle Lane Changes
If another vehicle enters the same lane as you, ACC will
not detect the vehicle until it is completely in the lane.
Be ready to take action and apply the brakes yourself.

Using ACC on Hills and When Towing a
Trailer
How well ACC will work on hills and when towing a
trailer depends on your vehicle's speed, vehicle load,
traffic conditions and the steepness of the hills. It may
not detect a vehicle in your lane while driving on hills.
When going up steep hills, you may want to use the
accelerator pedal to maintain your vehicle's speed.
When going downhill, especially when towing a trailer,
you may want to brake to keep your speed down.
Applying the brake disengages the system. You may
choose not to use ACC on steep hills, especially when
towing a trailer.
Disengaging ACC
To turn off the system, apply the brake pedal, press the
cancel button, or press the ACC button.
Erasing Set Speed Memory
Press the ACC button or turn the ignition off.
Other Messages
There are three additional messages that may appear
on the DIC. They are SERVICE RADAR CRUISE,
RADAR CRUISE NOT READY and CLEAN RADAR.
These messages will appear to indicate a problem
with the ACC. SeeDIC Warnings and Messages
on
page 4‑65for more information.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean the
lens. Remember, do not use ACC in icy conditions,
or when visibility is low, such as in fog, rain or snow.
The emblem/lens is located in the center of the grille.
To clean the emblem/lens, wipe the surface with a soft
cloth. After cleaning the emblem/lens, try to engage the
ACC. If you are unable to do so, see your dealer.

Airbag Readiness Light
The system checks the airbag's electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the
airbag modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 2‑54.
The airbag readiness light
flashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
fixed immediately.
{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away. If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also
come on. See
DIC Warnings and Messages
on
page 4‑65for more information.
Passenger Airbag Status Indicator
The vehicle has the passenger sensing system. See
Passenger Sensing Systemon page 2‑64for important
safety information. The overhead console has a
passenger airbag status indicator.
United StatesCanada
When the vehicle is started, the passenger airbag
status indicator will light ON and OFF, or the symbol for
on and off, for several seconds as a system check.
If you are using remote start to start the vehicle from a
distance, if equipped, you may not see the system
check.

Black plate (49,1)Cadillac DTS Owner Manual - 2011
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 frontal and seat-mounted side impact
airbags.
If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger frontal airbag and seat-mounted side impact
airbag are enabled (may inflate).
If the word OFF or the off symbol is lit on the passenger
airbag status indicator, it means that the passenger
sensing system has turned off the right front passenger
frontal and seat‐mounted side impact airbag.
If, after several seconds, both 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.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light
on page 4‑48
for more information, including important safety
information.

Tire Pressure Light
For vehicles with a Tire
Pressure Monitoring
System, this light comes
on briefly when the engine
is started. It provides
information about tire
pressures and the Tire
Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires is
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC)
on page 4‑59for more
information. Stop and check the tires as soon as it is
safe to do so. If underinflated, inflate to the proper
pressure. See Inflation - Tire Pressure
on page 6‑57for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about a
minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. SeeTire Pressure Monitor Operation
on
page 6‑61for more information.
Malfunction Indicator Lamp
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment.
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 Malfunction Indicator Lamp comes on and stays
on, while the engine is running, this indicates that there
is an OBD II problem and service is required.
4-54

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.
