2010 CADILLAC DTS warning light

Cruise Control
With cruise control, a speed of approximately 40 km/h(25 mph) or more can be maintained without keepingyour foot on the accelerator. Cruise control does not workat speeds below about 40 km/h (25 mph). A cruise controllight appears in the instrument panel cluster when thecruise control is on.
When the brakes are applied, the cruise controlshuts off.
{WARNING:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the cruise control on winding roads or in
heavy traffic.
Cruise control can be dangerous on slippery roads.
On such roads, fast changes in tire traction can
cause excessive wheel slip, and you could lose
control. Do not use cruise control on slippery roads.
If your vehicle is in cruise control when the TractionControl System (TCS) begins to limit wheel spin,the cruise control automatically turns off. SeeTractionControl System (TCS) on page 5-6. When roadconditions let you safely use it again, the cruise controlcan be turned back on.
Setting Cruise Control
{WARNING:
If you leave your cruise control on when you are
not using cruise, you might hit a button and go
into cruise when you do not want to. You could be
startled and even lose control. Keep the cruise
control switch off until you want to use cruise
control.

If this symbol does not appear, or disappears briefly,ACC will not respond to vehicles you may see ahead.
{WARNING:
When the Adaptive Cruise Control radar is blocked
by snow, ice, or dirt, it may not detect a vehicle
ahead. Adaptive Cruise Control may not have time
to slow your vehicle enough to avoid a collision.
Do not use Adaptive Cruise Control when the
radar is blocked by snow, ice, or dirt. Keep your
radar clean. See “Cleaning the System” later in
this section.
ACC automatically slows your vehicle down whenapproaching a slower moving vehicle. It then adjustsyour vehicle speed to follow the vehicle in front atthe selected follow distance. Your vehicle speedincreases or decreases to follow the vehicle in front ofyou, but will not exceed the set speed. It may applylimited braking, if necessary. When braking is active,your brake lights will come on. Braking may feelor sound different than if you were applying the brakesyourself. This is normal.
Stationary or Very Slow-Moving Objects
{WARNING:
Adaptive Cruise Control may not detect and react
to stationary or slow-moving vehicles or other
objects ahead of you. You could crash into an
object ahead of you. Do not use Adaptive Cruise
Control when approaching stationary or
slow-moving vehicles or other objects.
{WARNING:
Adaptive Cruise Control may not detect and react
to stationary or slow-moving vehicles or other
objects ahead of you. Your vehicle may accelerate
toward objects, such as a stopped vehicle that
suddenly appears after the lead vehicle changes
lanes. Your complete attention is always required
while driving and you should be ready to take
action and apply the brakes.

IntelliBeam™ Intelligent High-Beam
Headlamp Control System
For vehicles with this feature, be sure to read this entiresection before using it.
IntelliBeam is an enhancement to the vehicle’sheadlamp system. Using a digital light sensor on therearview mirror, this system turns the vehicle’shigh-beam headlamps on and off according tosurrounding traffic conditions.
The IntelliBeam system turns the high-beam headlampson when it is dark enough, there is no other trafficpresent, and the IntelliBeam system is enabled.
Turning On and Enabling IntelliBeam™
Press and release the IntelliBeam button on the insiderear view mirror. The IntelliBeam indicator on themirror turns on to indicate the system is on. Once thesystem has been turned on, it remains on each time thevehicle is started, but the IntelliBeam system must beenabled.
To enable the IntelliBeam system, turn the exterior lampcontrol to AUTO, with the turn signal/multifunctionlever in its neutral position. The High-Beam On Lightappears on the instrument panel cluster when thehigh-beams are on. SeeHighbeam On Light onpage 4-61.

Wiper Activated Headlamps
This feature activates the headlamps and parking lampsafter the windshield wipers are turned on and havecompleted eight wipe cycles within four minutes.
When the ignition is turned to LOCK/OFF, thewiper-activated headlamps immediately turn off. Thewiper-activated headlamps also turn off if the windshieldwipers are turned off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp controlis left on in either the headlamp or parking lamp positionand the driver’s door is opened with the ignition off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier forothers to see the front of your vehicle during theday. Fully functional daytime running lamps are requiredon all vehicles first sold in Canada.
The DRL system makes the turn signal lamps come onwhen 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 Systemon page 4-36.
When DRL are on, no other exterior lamps such as theparking lamps, taillamps, etc. will be on when theDRL are being used. The instrument panel will not be litup either.
When automatic lighting is on and it is dark enoughoutside, the turn signal lamps turn off and normallow-beam headlamp operation occurs.
When automatic lighting is on and it is bright enoughoutside, the regular lamps go off, and the DRLtakes over. If the vehicle is started in a dark garage, theautomatic headlamp system comes on immediately.Once you leave the garage, it will take approximatelyone minute for the automatic headlamp system tochange to DRL if there is light outside. During that delay,the instrument panel cluster may not be as bright asusual. Make sure the instrument panel brightness knobis in the full bright position. SeeInstrument PanelBrightness on page 4-31.
Turning on automatic lighting or the headlamps willdeactivate the DRL. If the parking lamps or thefog lamps were turned on instead, the DRL will stilldeactivate.
4-29

Reading Lamps
The reading lamps are located on the overhead consoleon the headliner and in the rear door opening. Theselamps come on automatically when any door is openedand it is dark outside.
For manual operation, press the button to turn them on.Press it again to turn them off.
If the reading lamps are left on, they automatically shutoff 10 minutes after the ignition has been turned off.
Footwell Lamps
For vehicles with footwell lamps, they are located underthe instrument panel and at the rear of the frontseats. These lamps provide soft light to the front andrear floor areas. They dim with the instrument panelcluster lights.
Footwell lighting brightness can be adjusted with theinstrument panel brightness control located belowthe exterior lamps control. SeeInstrument PanelBrightness on page 4-31. The footwell lights will turn offbefore the instrument panel lights are at their lowestlevel of brightness.
Battery Load Management
This feature monitors the vehicle’s electrical load anddetermines when the battery is in a heavy dischargecondition. During times of high electrical loading,the engine may idle at a higher revolutions per minute(rpm) setting than normal to make sure the batterycharges. High electrical loads may occur when severalof the following are on: headlamps, high beams, foglamps, rear window defogger, the climate control fan athigh speeds, heated seats and engine cooling fans.
If the battery continues to discharge, even withthe engine idling at a higher rpm setting, some electricalloads will automatically be reduced. When this occurs,the rear window defogger may take slightly longerto clear the glass, the heated seats may not get as warmas they usually do and the climate control fan may cutback to a lower speed. For more battery savinginformation, see “Battery Saver Active Message” underDIC Warnings and Messages on page 4-67.
4-32

Electric Power Management
The vehicle has Electric Power Management (EPM) thatestimates the battery’s temperature and state ofcharge. It then adjusts the voltage for best performanceand extended life of the battery.
When the battery’s state of charge is low, the voltage israised slightly to quickly bring the charge back up.When the state of charge is high, the voltage is loweredslightly to prevent overcharging. If the vehicle has avoltmeter gage or a voltage display on the DriverInformation Center (DIC), you may see the voltage moveup or down. This is normal. If there is a problem, analert will be displayed.
The battery can be discharged at idle if the electricalloads are very high. This is true for all vehicles. This isbecause the generator (alternator) may not bespinning fast enough at idle to produce all the powerthat is needed for very high electrical loads.
A high electrical load occurs when several of thefollowing are on, such as: headlamps, high beams, foglamps, rear window defogger, climate control fan athigh speed, heated seats, engine cooling fans, trailerloads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of thebattery. It does this by balancing the generator’s outputand the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, wheneverneeded. It can temporarily reduce the power demands ofsome accessories.
Normally, these actions occur in steps or levels, withoutbeing noticeable. In rare cases at the highest levelsof corrective action, this action may be noticeable to thedriver. If so, a Driver Information Center (DIC)message might be displayed, such as BATTERYSAVER ACTIVE, BATTERY VOLTAGE LOW, orLOW BATTERY. If this message is displayed, it isrecommended that the driver reduce the electrical loadsas much as possible. SeeDIC Warnings and Messageson page 4-67.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s batteryagainst drainage from the interior lamps, trunk lamp,glove box lamp, or the garage door opener. When theignition is turned off, the power to these features willautomatically turn off after 10 minutes. Power willbe restored for an additional 10 minutes if any door ortrunk is opened, or the courtesy lamp switch isturned on.

Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something iswrong before it becomes serious enough to causean expensive repair or replacement. Paying attention tothe warning lights and gages could prevent injury.
Warning lights come on when there might be or there isa problem with one of the vehicle’s functions. Somewarning lights come on briefly when the engine is startedto indicate they are working.
Gages can indicate when there might be or there is aproblem with one of the vehicle’s functions. Often gagesand warning lights work together to indicate a problemwith the vehicle.
When one of the warning lights comes on and stays onwhile driving, or when one of the gages shows therecould be a problem, check the section that explains whatto do. Follow this manual’s advice. Waiting to dorepairs can be costly and even dangerous.
