2010 CADILLAC DTS air condition

D (Drive) can be used for towing. You may want to shiftthe transmission to 3 (Third) or, if necessary, to alower gear if the transmission shifts too often underheavy loads and/or hilly conditions.
SeeTowing a Trailer on page 5-26for more information.
3 (Third):This position is also used for normaldriving. However, it reduces vehicle speed more thanD (Drive) without using the brakes. You might choose3 (Third) instead of D (Drive) when driving on hilly,winding roads, when towing a trailer, so there is lessshifting between gears and when going down asteep hill.
2 (Second):This position reduces vehicle speed morethan 3 (Third) without using the brakes. You can use2 (Second) on hills. It can help control vehicle speed asyou go down steep mountain roads, but then youwould also want to use the brakes off and on.
Notice:Do not shift into 2 (Second) unless you aregoing slower than 65 mph (105 km/h), or you candamage the engine and/or transmission.
1 (First):This position reduces vehicle speed evenmore than 2 (Second) without using the brakes. You canuse it on very steep hills, or in deep snow or mud.If the shift lever is put in 1 (First) while the vehicle ismoving forward, the transmission will not shift into firstgear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle inone place on a hill using only the acceleratorpedal may damage the transmission. The repair willnot be covered by the vehicle warranty. If youare stuck, do not spin the tires. When stopping on ahill, use the brakes to hold the vehicle in place.
Performance Shifting
If the vehicle has this feature, it can detect a change indriving patterns. If you make an aggressive drivingmaneuver, the vehicle’s transmission automatically shiftsto the lowest possible gear to maximize vehicleperformance. The vehicle will automatically return tonormal operation when you return to normal drivingpatterns.

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporarycondition, the message PARK ASSIST OFF will bedisplayed on the DIC and a red light will be shown onthe rear URPA display when the shift lever is moved intoR (Reverse). This occurs under the following conditions:
•The driver disables the system.
•The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,ice and slush. For cleaning instructions, seeWashing Your Vehicle on page 6-95.
•A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during thelast drive cycle, the red light may illuminate inthe rear display. Once the attached object isremoved, URPA will return to normal operation.
•A tow bar is attached to the vehicle.
•The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
•Other conditions may affect system performance,
such as vibrations from a jackhammer or thecompression of air brakes on a very large truck.
If the system is still disabled after driving forward atleast 25 km/h (15 mph), take the vehicle to yourdealer/retailer.
Side Blind Zone Alert (SBZA)
The vehicle may have a Side Blind Zone Alert (SBZA)system. Read this entire section before using the system.
{WARNING:
SBZA is only a lane changing aid and does not
replace driver vision. SBZA does not detect:
•Vehicles outside the side blind zones which
may be rapidly approaching.
•Pedestrians, bicyclists, or animals.
Failure to use proper care when changing lanesmay result in damage to the vehicle, injury, ordeath. Always check the outside and rearviewmirrors, glance over your shoulder, and use theturn signal before changing lanes.
When the system detects a vehicle in the side blindzone, amber SBZA displays will light up in the sidemirrors. This indicates that it may be unsafe to changelanes. Before making a lane change, always checkthe SBZA display, check the outside and rearviewmirrors, look over your shoulder for vehicles andhazards, and use the turn signal.

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.

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.

Manual Operation
9(Off):Turns the entire climate control system off.
Outside air still enters the vehicle and is directed to thefloor. The airflow direction and temperature can beadjusted, as indicated below.
If the temperature is adjusted while the system is off,the display will light to show the current settings.
wx(Driver’s Temperature Controls):Press the up
or down buttons next to the fan control to manuallyincrease or decrease the temperature inside the vehicle.
wx(Passenger’s Temperature Controls):Press
the up or down buttons next to the air deliverymode control to manually increase or decrease thetemperature for the front passenger. If the passengerclimate control system is off, pressing one of thesebuttons turns it on.
9(Fan Control):Turn clockwise or counterclockwise
to increase or decrease the fan speed. Turning thiscontrol completely counterclockwise will turn onthe automatic fan operation. If the airflow seems lowwhen the fan speed is at the highest setting, thepassenger compartment air filter may need to bereplaced. SeePassenger Compartment Air Filter onpage 4-44.
Air Delivery Mode Control:Turn clockwise orcounterclockwise to change the current airflow mode.
Select one of the following:
AUTO:Turns on the automatic delivery mode operation.
F(Vent):Air is directed to the instrument panel
outlets.
*(Bi-Level):Air is divided between the instrument
panel and the floor outlets. In automatic operation,cooler air is directed to the upper outlets and warmer airto the floor outlets.
7(Floor):Air is directed to the floor outlets with some
air directed to the side window outlets and thewindshield.
If recirculation is selected, it only stays on for threeminutes to reduce windshield fogging.
W(Floor/Defog):This mode clears the windows of
fog or moisture. Air is directed to the floor outlets, withsome air going to the side window outlets andwindshield. When selected, the system turns offrecirculation and runs the air conditioning compressorunless the outside temperature is at or below freezing.The recirculation mode cannot be selected while inthe floor/defog mode.
4-38

0(Defrost):This mode clears the windshield of fog
or frost more quickly. Air is directed to the windshieldand side window outlets. When selected, the systemautomatically turns off recirculation and runs theair conditioning compressor, unless the outsidetemperature is at or below freezing. Recirculation cannotbe selected while in the defrost mode. Do not drivethe vehicle until all the windows are clear.
For professional vehicles, air will be allowed to flowthrough the rear outlets. For quicker defrost, press theAUX button on the front climate control system sothat the light is not lit.
#(Air Conditioning):Press to turn the air
conditioning system on or off and override the automaticsystem. When in AUTO, the air conditioning compressorcomes on automatically, as necessary. To avoidwindow fogging on rainy and humid days attemperatures above freezing, run the air conditioning.
The air conditioning system removes moisture fromthe air, so a small amount of water may drip under thevehicle while idling or after turning off the engine.This is normal.
:(Outside Air):Press to turn the outside air mode
on or off. An indicator light comes on to show it ison. Air is pulled from outside the vehicle.
Pressing?will cancel this mode.
?(Recirculation):Press to turn the recirculation
mode on or off. An indicator light below the buttoncomes on to show that this mode is on. This moderecirculates and helps to quickly cool the air inside thevehicle. It can be used to prevent outside air andodors from entering the vehicle. This mode cannot beselected while in the defog or defrost modes. If you try toselect the recirculation mode, the indicator lightflashes three times and turns off.
Operation in this mode during periods of high humidityand cool outside temperatures may result in increasedwindow fogging. If window fogging is experienced, selectthe defrost mode.
AUX:For vehicles with a rear climate control system,press to turn the rear climate control fan on for automaticoperation. After the AUX button is pressed, the indicatorlight comes on. Press the button again to turn theauxiliary fan off. SeeRear Climate Control System onpage 4-42.
PASS (Passenger Climate Control):Press to turn thepassenger climate control systems on or off. Whenthe passenger climate control system is on, thepassenger temperature setting is displayed. Thetemperature selected by the front passenger alsocontrols the rear system air temperature unless the rearseat passengers select their own comfort setting.
If the PASS button is pressed to turn the passengertemperature setting off, the driver’s temperatureknob will control the temperature for the entire vehicle.
