sensor CADILLAC DTS 2010 1.G User Guide

The system operates in the delay mode. If the system isleft on for long periods of time, occasional wipes mayoccur without any moisture on the windshield. Thisis normal and indicates that the Rainsense™systemis active.
The Rainsense™system is activated by turning thewiper control band to one of the five sensitivity levelswithin the delay area. The position closest to off isthe lowest sensitivity setting, level one. This allows morerain or snow to collect on the windshield betweenwipes. Turning the wiper band away from you to highersensitivity levels increases the sensitivity of thesystem and frequency of wipes. The highest sensitivitysetting, level five is closest to low. A single wipe willoccur each time you turn the wiper stalk to a highersensitivity level to indicate that the sensitivity level hasbeen increased.
Notice:Going through an automatic car wash withthe wipers on can damage them. Turn the wipersoff when going through an automatic car wash.
The MIST and wash cycle operates as normal and arenot affected by the Rainsense™function. The systemcan be overridden at any time by manually changing thewiper control to low or high speed.
Notice:Do not place stickers or other items on theexterior glass surface directly in front of the rainsensor.

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.
4-26

Driving with IntelliBeam™
IntelliBeam only activates the high-beams when drivingover 20 mph (32 km/h).
The high-beam headlamps remain on, under theautomatic control of IntelliBeam, until any of thefollowing situations occur:
•The system detects an approaching vehicle’s
headlamps.
•The system detects a preceding vehicle’s taillamps.
•The outside light is bright enough that high-beam
headlamps are not required.
•The vehicle’s speed drops below 15 mph (24 km/h).
•The headlamp stalk is moved forward to the
high-beam position or the flash-to-pass feature isused. SeeHeadlamp High/Low-Beam Changeron page 4-6andFlash-to-Pass on page 4-10.
When either of these conditions occur, theIntelliBeam feature is disabled and the IntelliBeamlight in the mirror turns off until the high-beam stalk isreturned to the neutral position.
•If IntelliBeam was using low-beams prior to this
action, the IntelliBeam feature is temporarilydisabled until the stalk is returned to theneutral position.
•The exterior lamp control is turned to any setting
except AUTO.
When this occurs, IntelliBeam is disabled until thecontrol is turned back to the AUTO position.
•The IntelliBeam system is turned off at the inside
rearview mirror.
IntelliBeam might not turn off the high-beams if thesystem cannot detect other vehicle’s lamps because ofany of the following:
•The other vehicle’s lamp(s) are missing, damaged,
obstructed from view, or otherwise undetected.
•The other vehicle’s lamp(s) are covered with dirt,
snow, and/or road spray.
•The other vehicle’s lamp(s) cannot be detected due
to dense exhaust, smoke, fog, snow, road spray,mist, or other airborne obstructions.
•Your vehicle’s windshield is dirty, cracked, or
obstructed by something that blocks the view of theIntelliBeam light sensor.
•Your vehicle’s windshield is covered with ice, dirt,
haze, or other obstructions.
4-27

•Your vehicle is loaded such that the front end of the
vehicle points upward, causing the IntelliBeamsensor to aim high and not detect headlamps andtaillamps.
•You are driving on winding or hilly roads.
You might need to manually disable or cancel thehigh-beam headlamps by turning the low-beamheadlamps on, if any of the above conditions exist.

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.

Push the button in and release to extend the button.Turn the button clockwise or counterclockwise tobrighten or dim the lights.
Courtesy Lamps
The courtesy lamps are located on the headliner abovethe rear seat. These lamps come on by turning theinstrument panel brightness knob fully clockwise or whenany door is opened and it is dark outside. Puddle lampsare located on the bottom of the front and rear door trim.
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
This feature prohibits dimming of the digital displays andbacklighting during daylight hours when the key is inthe ignition and the headlamps are on. This feature isfully automatic. When the light sensor reads darknessoutside and the parking lamps are active, the digitaldisplays can be adjusted by turning the instrument panelbrightness knob counterclockwise to dim and clockwiseto brighten lighting.

Automatic Operation
AUTO9(Automatic Fan):When this position is
selected on the fan control, the system adjusts the fanspeed. If the OnStar®system is activated when thisposition is selected, the climate control fan speedwill lower.
AUTO (Automatic Mode):
1. Turn the fan control to the AUTO position.
2. Turn the mode control to the AUTO position.
3. Adjust the temperature to a comfortable settingbetween 21°C (68°F) and 26°C (78°F).
Choosing the coldest or warmest temperature settingwill not cause the system to heat or cool any faster.In cold weather, the system will start at reduced fanspeeds to avoid blowing cold air into the vehicle untilwarmer air is available. The system starts outblowing air at the floor but may change modesautomatically as the vehicle warms up to maintain thechosen temperature setting. The length of timeneeded to warm the interior depends on the outsidetemperature and temperature of the vehicle.
4. Wait 20 to 30 minutes for the system to stabilize inorder for the system to regulate automatically. Thenadjust the temperature as necessary to find yourcomfort setting.
Do not cover the solar sensor located in the center ofthe instrument panel near the windshield. For moreinformation on the solar sensor, see “Sensors” later inthis section.
After the vehicle is started, the display shows the interiortemperature settings and the outside temperature.
If the AUTO position is selected on the fan or modecontrol, the system automatically controls the airconditioning compressor. The A/C compressor will runautomatically even at cool outside temperatures in orderto dehumidify the air. The A/C indicator light is lit whenthe system is operating automatically, even at near
freezing outside temperatures. Press#on the fan
control to turn off the A/C. For improved window clearingperformance in defog or defrost modes, the A/Ccompressor runs automatically.
h(AUTO RECIRCULATION):If the AUTO position
is selected on either the fan or mode control, thesystem automatically controls the air inlet to supplyfresh outside air or recirculate the interior air to cool thecar faster. The light on the recirculation button willcome on when the system changes to recirculation.
Outside air can be forced by pressinghwhen
the light is lit. For vehicles without rear climate controls,
press:to force outside air. The next time AUTO
fan or mode is selected, the air inlet will reset back toAUTO operation.

Rear Window Defogger
The rear window defogger uses a warming grid toremove fog or frost from the rear window.
<(Rear Defogger):Press to turn the rear window
defogger on or off. Be sure to clear as much snowfrom the rear window as possible. The rear windowdefogger will turn off approximately 20 minutes after thebutton is pressed if the vehicle is moving at slowervehicle speeds. At higher vehicle speeds, the reardefogger may stay on continuously. Each additionalpress will run the defogger for approximately 10 minutes.
The heated outside rearview mirrors will turn on tohelp clear fog or frost from the surface of the mirrorwhen the rear window defogger is on.
Notice:Do not use a razor blade or sharp object toclear the inside rear window. Do not adhereanything to the defogger grid lines in the rear glass.These actions may damage the rear defogger.Repairs would not be covered by your warranty.
Sensors
The solar sensor, located in the defrost grille, middle ofthe instrument panel, monitors the solar radiation.Do not cover the solar sensor or the system will notwork properly.
4-40

There is also an interiortemperature sensorlocated next to the steeringwheel that measures thetemperature of the airinside the vehicle.
There is also an exterior temperature sensor locatedbehind the front grille. This sensor reads the outside airtemperature and helps maintain the temperatureinside the vehicle. Any cover on the front of the vehiclecould cause a false reading in the displayedtemperature.
In order to prevent false temperature readings atstartup, the displayed temperature will not change untilthe following occurs:
•Vehicle speed is above 16 km/h (10 mph) for
5 minutes.
•Vehicle speed is above 51 km/h (32 mph) for 2 and
a half minutes.
The climate control system uses the information fromthese sensors to maintain your comfort setting byadjusting the outlet temperature, fan speed, and the airdelivery mode. The system may also supply coolerair to the side of the vehicle facing the sun. Therecirculation mode will also be used as needed tomaintain cool outlet temperatures.
Outlet Adjustment
For the front outlets, use the thumbwheel located beloweach outlet to change the direction of the airflow. Use thethumbwheel located next to the outlets to shut the airflowor to open the outlets and re-direct the air.
For the rear outlets, slide the lever left or right and up ordown to change the direction of the airflow.
Operation Tips
•Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that mayblock the flow of air into your vehicle.
•Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle moreeffectively.

Airbag Readiness Light
The system checks the airbag’s electrical system forpossible malfunctions. If the light stays on it indicatesthere is an electrical problem. The system checkincludes the airbag sensor, the pretensioners, the airbagmodules, the wiring and the crash sensing anddiagnostic module. For more information on the airbagsystem, seeAirbag System on page 2-58.
The airbag readiness lightflashes for a few secondswhen the engine isstarted. If the light doesnot come on then, have itfixed 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 airbagDriver Information Center (DIC) message can also comeon. SeeDIC Warnings and Messages on page 4-67for more information.
