2009 CADILLAC DTS warning

Alerting the Driver
The ACC alert symbol is
located on the display at
the top of the instrument
panel to the right of the
driver.
The alert symbol ashes and a warning beep sounds
when driver action may be required. If ACC is engaged,
the alert symbol will ash when:
ACC cannot apply sufficient braking because you
are approaching a vehicle too rapidly.
The vehicle speed drops below about
20 mph (32 km/h).
A temporary condition prohibits ACC from operating.
SeeDIC Warnings and Messages on page 3-73for
more information.
A malfunction is detected in the system. SeeDIC
Warnings and Messages on page 3-73for more
information.
SeeDefensive Driving on page 4-2.
{CAUTION:
Adaptive Cruise Control has only limited braking
ability to slow your vehicle. In some cases, Adaptive
Cruise Control may not have time to slow your
vehicle enough to avoid a collision. Be ready to
take action and apply the brakes yourself.
SeeDefensive Driving on page 4-2.
Approaching and Following a Vehicle
The vehicle ahead symbol
is located on the top of the
instrument panel to the
right of the driver.
The vehicle ahead symbol only appears when a vehicle
is detected in your path.
If this symbol does not appear, or disappears briey,
ACC will not respond to vehicles you may see ahead.
3-24

Low-Speed Deactivation
If your vehicle speed falls below 20 mph (32 km/h) while
following a vehicle ahead, ACC will begin to disengage.
The Driver Alert symbol will ash and the warning beep
will sound. The driver must take action since ACC will not
slow the vehicle to a stop.
Passing a Vehicle/ACC Override
To increase speed to pass a vehicle, use the
accelerator pedal. While you are doing this, the system
will not automatically apply the brakes. A message will
appear on the DIC. SeeDIC Warnings and Messages
on page 3-73. Once you remove your foot from the
accelerator pedal, ACC will return to normal operation
and be able to apply the brakes, if needed.
{CAUTION:
If you rest your foot on the accelerator pedal,
the system will not automatically apply the brakes.
You could crash into a vehicle ahead of you.
Do not rest your foot on the accelerator pedal
when using Adaptive Cruise Control.
Curves in the Road
{CAUTION:
Due to Adaptive Cruise Control limitations in
curves, it may respond to a vehicle in another
lane, or may not have time to react to a vehicle in
your lane. You could crash into a vehicle ahead
of you, or lose control of your vehicle. Give extra
attention in curves and be ready to use the brakes
if necessary. Select an appropriate speed while
driving in curves.
ACC may operate differently in a sharp curve. It may
reduce your vehicle speed if the curve is too sharp.

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 3-73for 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/retailer.
Exterior Lamps
The exterior lamps control
is located on the instrument
panel to the left of the
steering wheel.
It controls the following systems:
Headlamps
Taillamps
Parking Lamps
License Plate Lamps
Instrument Panel Lights
Fog Lamps
3-29

The exterior lamps control has four positions:
O(Off):Turns off the exterior lamps except for
Daytime Running Lamps (DRL).
AUTO (Automatic):Automatically turns on the
headlamps at normal brightness, together with the
following:
Parking Lamps
Instrument Panel Lights
IntelliBeam™
;(Parking Lamps):Turns on the parking lamps
together with the following:
Instrument Panel Lights
License Plate Lamps
Taillamps
Side Marker Lamps
The parking brake indicator light comes on and stays
on while the parking lamps are on with the engine
off and the ignition in ACC/ACCESSORY or ON/RUN.
2(Headlamps):Turns on the headlamps together
with the previously listed lamps. A warning chime sounds
if the driver’s door is opened while the ignition switch is off
and the headlamps are on.
#(Fog Lamps):Press the exterior lamps control to
turn on the fog lamps. SeeFog Lamps on page 3-34.
IntelliBeam™ Intelligent High-Beam
Headlamp Control System
For vehicles with this feature, be sure to read this entire
section before using it.
IntelliBeam is an enhancement to the vehicle’s
headlamp system. Using a digital light sensor on
the rearview mirror, this system turns the vehicle’s
high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam system turns the high-beam headlamps
on when it is dark enough, there is no other traffic
present, and the IntelliBeam system is enabled.
Turning On and Enabling IntelliBeam™
Press and release the IntelliBeam button on the inside
rear view mirror. The IntelliBeam indicator on the mirror
turns on to indicate the system is on. Once the system
has been turned on, it remains on each time the vehicle
is started, but the IntelliBeam system must be enabled.
To enable the IntelliBeam system, turn the exterior lamp
control to AUTO, with the turn signal/multifunction lever in
its neutral position. The High-Beam On Light appears on
the instrument panel cluster when the high-beams are on.
SeeHighbeam On Light on page 3-66.
3-30

Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required
on all vehicles rst sold in Canada.
The DRL system makes the turn signal lamps come on
when the following conditions are met:
It is still daylight and the ignition is on.
The exterior lamp control is in the off position.
The transmission is not in P (Park)
(United States only).
The light sensor is covered or not detecting light.
See “Sensors” underDual Climate Control System
on page 3-40.
When DRL are on, no other exterior lamps such as the
parking lamps, taillamps, etc. will be on when the DRL
are being used. The instrument panel will not be lit
up either.When automatic lighting is on and it is dark enough
outside, the turn signal lamps turn off and normal
low-beam headlamp operation occurs.
When automatic lighting is on and it is bright enough
outside, the regular lamps go off, and the DRL takes over.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once you
leave the garage, it will take approximately one minute
for the automatic headlamp system to change to DRL if
there is light outside. During that delay, the instrument
panel cluster may not be as bright as usual. Make sure
the instrument panel brightness knob is in the full bright
position. SeeInstrument Panel Brightness on page 3-34.
Turning on automatic lighting or the headlamps will
deactivate the DRL. If the parking lamps or the fog lamps
were turned on instead, the DRL will still deactivate.
To idle the vehicle with the DRL off at night, turn off
automatic lighting and shift the transmission into P (Park).
Placing the vehicle in P (Park) disables the DRL. The
DRL will stay off until the vehicle is shifted out of P (Park).
To drive the vehicle with the DRL off, turn off automatic
lighting and manually turn on the parking lamps or
fog lamps, if the vehicle has them.
The regular headlamp system should be turned on
when needed.
3-33

Footwell Lamps
For vehicles with footwell lamps, they are located
under the instrument panel and at the rear of the
front seats. These lamps provide soft light to the front
and rear oor areas. They dim with the instrument
panel cluster lights.
Footwell lighting brightness can be adjusted with the
instrument panel brightness control located below the
exterior lamps control. SeeInstrument Panel Brightness
on page 3-34. The footwell lights will turn off before
the instrument panel lights are at their lowest level of
brightness.
Battery Load Management
This feature monitors the vehicle’s electrical load and
determines when the battery is in a heavy discharge
condition. During times of high electrical loading, the
engine may idle at a higher revolutions per minute (rpm)
setting than normal to make sure the battery charges.
High electrical loads may occur when several of the
following are on: headlamps, high beams, fog lamps,
rear window defogger, the climate control fan at high
speeds, heated seats and engine cooling fans.If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass, the heated seats may not get as
warm as they usually do and the climate control fan
may cut back to a lower speed. For more battery
saving information, see “Battery Saver Active Message”
underDIC Warnings and Messages on page 3-73.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage
is raised slightly to quickly bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
3-36

The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not
be spinning fast enough at idle to produce all the
power that is needed for very high electrical loads.
A high electrical load occurs when several of the
following are on, such as: headlamps, high beams,
fog lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase engine
idle speed to generate more power, whenever needed.
It can temporarily reduce the power demands of some
accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or LOW BATTERY. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 3-73.Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, or the garage door opener. When the
ignition is turned off, the power to these features will
automatically turn off after 10 minutes. Power will be
restored for an additional 10 minutes if any door or trunk
is opened, or the courtesy lamp switch is turned on.
Battery Run-Down Protection
This feature helps prevent the battery from being
drained, if the interior courtesy lamps, reading/map
lamps, visor vanity lamps or trunk lamp are accidentally
left on. If any of these lamps are left on, they
automatically turn off after 10 minutes, if the ignition
is off. The lamps will not come back on again until
one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then on
again.
The headlamps will time-out after 10 minutes, if they are
manually turned on with the ignition on or off.

cover into place.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is
started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there may
be a problem, check the section that explains what to do.
Follow this manual’s advice. Waiting to do repairs can be
costly and even dangerous.
