2010 CADILLAC DTS headlamp

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

To idle the vehicle with the DRL off at night, turn offautomatic lighting and shift the transmission into P (Park).Placing the vehicle in P (Park) disables the DRL. TheDRL will stay off until the vehicle is shifted out of P (Park).
To drive the vehicle with the DRL off, turn off automaticlighting and manually turn on the parking lamps orfog lamps, if the vehicle has them.
The regular headlamp system should be turned onwhen needed.
Fog Lamps
The fog lamps button is on the exterior lamps control tothe left of the steering column.
#(Fog Lamps):Press the exterior lamps button to
turn the fog lamps on or off. A light comes on inthe instrument panel cluster when the fog lamps are inuse. SeeInstrument Panel Cluster on page 4-47.The ignition must be in the ON/RUN position for thefog lamps to work.
The fog lamps will go off when the headlamps arechanged to high-beam.
Some localities have laws that require the headlamps tobe on along with the fog lamps.
Cornering Lamps
The cornering lamps come on when the headlamps orparking lamps are on and you signal a turn with themultifunction lever. They provide more light forcornering.
Exterior Lighting Battery Saver
If the exterior lamp button has been left on, the exteriorlamps will turn off about 10 minutes after the ignitionis turned to LOCK/OFF and a door has been opened.This protects against draining the battery if theheadlamps or parking lamps are accidentally left on.If you need to leave the lamps on for more than10 minutes, use the exterior lamp control to turn thelamps back on after the ignition is turned to LOCK/OFFand any door is opened.

Professional vehicles have an additional dome lampand also opera lamps.
Entry Lighting
This feature turns on the courtesy lamps and thebacklighting for the door switches and the exterior lampcontrol when a door is opened or if the remote keylessentry transmitter unlock button is pressed. If activateddue to the transmitter, the lighting remains active forabout 40 seconds. Since the entry lighting system usesthe light sensor, it must be dark outside in order for thecourtesy lamps to turn on. The courtesy lamps turn offapproximately 25 seconds after the last door is closed.They will dim to off if the ignition key is turned toON/RUN, or immediately deactivate if the power locksare activated.
Parade Dimming

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.

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.
4-33

Battery Run-Down Protection
This feature helps prevent the battery from beingdrained, if the interior courtesy lamps, reading/maplamps, visor vanity lamps or trunk lamp are accidentallyleft on. If any of these lamps are left on, theyautomatically turn off after 10 minutes, if the ignition isoff. The lamps will not come back on again untilone of the following occurs:
•The ignition is turned on.
•The exterior lamps control is turned off, then on
again.
The headlamps will timeout after 10 minutes, if they aremanually turned on with the ignition on or off.
Accessory Power Outlet(s)
The accessory power outlets can be used to plug inelectrical equipment, such as a cellular telephone.
If the vehicle has a center console, the power outlet islocated inside the lower storage area. Some vehiclesmay have an outlet on the right front lower part ofthe driver’s seat and under the climate control systemnext to the ashtray. SeeCenter Console Storageon page 3-55.
There are two accessory power outlets in the rear seatarea located on the door armrests next to theashtrays.
There may be a small cap that must be removed toaccess the accessory power outlet. When not using theoutlet be sure to cover it with the protective cap.
The accessory power outlet can be used at any time.
Notice:Leaving electrical equipment plugged in foran extended period of time while the vehicle is offwill drain the battery. Power is always suppliedto the outlets. Always unplug electrical equipmentwhen not in use and do not plug in equipmentthat exceeds the maximum 20 ampere rating.
Certain accessory power plugs may not be compatibleto the accessory power outlet and could result inblown vehicle or adapter fuses. If you experience aproblem see your dealer/retailer for additionalinformation on the accessory power outlets.
Notice:Adding any electrical equipment to thevehicle can damage it or keep other componentsfrom working as they should. The repairs would notbe covered by the vehicle warranty. Do not useequipment exceeding maximum amperage rating of20 amperes. Check with your dealer/retailer beforeadding electrical equipment.

Highbeam On Light
This light comes on whenthe high-beam headlampsare in use.
SeeHeadlamp High/Low-Beam Changer on page 4-6for more information.
Fuel Gage
The fuel gage showsapproximately how muchfuel is in the tank. Itworks only when theengine is on.
An arrow on the fuel gage indicates the side of thevehicle the fuel door is on.
If the fuel supply gets low, the FUEL LEVEL LOWmessage appears in the Driver Information Center anda single chime sounds. SeeDIC Warnings andMessages on page 4-67for more information.
Here are a few situations that may occur with the fuelgage. All of these situations are normal and do notindicate that anything is wrong with the fuel gage:
•At the gas station the gas pump shuts off before the
gage reads full.
•The gage 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 gage indicated. For example, the gage mayhave indicated that the tank was half full, butit actually took a little more or less than half thetank’s capacity to fill the tank.
Driver Information Center (DIC)
The Driver Information Center (DIC) gives you thestatus of many of your vehicle’s systems. The DIC isalso used to display warning/status messages. Allmessages will appear in the DIC display located at thebottom of the instrument panel cluster, below thetachometer and speedometer. The DIC buttons arelocated on the instrument panel, to the left of thesteering wheel.
