light CADILLAC DTS 2010 1.G Owners Manual

You will not see the battery of your vehicle underthe hood. It is located under the rear passenger’sseat. You will not need to access the batteryfor jump starting. The remote terminals are forthat purpose.
{WARNING:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
{WARNING:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough water. You do not
need to add water to the battery installed in your
new vehicle. But if a battery has filler caps, be
sure the right amount of fluid is there. If it is low,
add water to take care of that first. If you do not,
explosive gas could be present.
Battery fluid contains acid that can burn you. Do
not get it on you. If you accidentally get it in your
eyes or on your skin, flush the place with water
and get medical help immediately.

It is recommended that the vehicle is taken to yourdealer/retailer for service if the headlamps need to bere-aimed. It is possible however, to re-aim theheadlamps as described.
Notice:To make sure the headlamps are aimedproperly, read all the instructions before beginning.Failure to follow these instructions could causedamage to headlamp parts.
The vehicle should:
•Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall.
•Have all four tires on a level surface which is level
all the way to the wall.
•Be placed so it is perpendicular to the wall.
•Not have any snow, ice, or mud on it.
•Be fully assembled and all other work stopped while
headlamp aiming is being performed.
•Be normally loaded with a full tank of fuel and one
person or 160 lbs (75 kg) sitting on the driver seat.
•Have all tires properly inflated.
•Have the spare tire is in its original location in the
vehicle.
Headlamp aiming is done with the vehicle’s low-beamheadlamps. The high-beam headlamps will be correctlyaimed if the low-beam headlamps are aimed properly.
To adjust the vertical aim:
1. Open the hood. SeeHood Release on page 6-11for more information.
2. Find the center line running through the lens of theheadlamp.
3. Record the distance from the ground to the centerline running through the lens of the headlamp.
6-41

4. At a wall, measure from the ground upward (A) tothe recorded distance from Step 3 and mark it.
5. Draw or tape a horizontal line (B) the width of thevehicle at the wall where it was marked in Step 4.
Notice:Do not cover a headlamp to improve beamcut-off when aiming. Covering a headlamp maycause excessive heat build-up which may causedamage to the headlamp.
6. Turn on the low-beam headlamps and place apiece of cardboard or equivalent in front of theheadlamp not being aimed. This should allow onlythe beam of light from the headlamp beingaimed to be seen on the flat surface.
7. Locate the vertical headlamp aiming screws. Theyare located under the hood near each headlampassembly. First lift the flap to access either of them.Each one is the top outboard screw by the “ V” on thecover panel next to the aiming flap.
The adjustment screw can be turned with a 6 mmhex wrench.
8. Turn the vertical aiming screw until the headlampbeam is aimed to the horizontal tape line. Turn itclockwise or counterclockwise to raise or lower theangle of the beam.
The top edge of the cut-off should be positioned atthe bottom edge of the horizontal tape line.
6-42

9. Make sure that the light from the headlamp ispositioned at the bottom edge of the horizontal tapeline. The lamp on the left (A) shows the correctheadlamp aim. The lamp on the right (B) shows theincorrect headlamp aim.
10. Repeat Steps 7 through 9 for the oppositeheadlamp.
Bulb Replacement
It is recommended that all bulbs be replaced by yourdealer/retailer.
High Intensity Discharge (HID)
Lighting
{WARNING:
The low beam high intensity discharge lighting
system operates at a very high voltage. If you try to
service any of the system components, you could
be seriously injured. Have your dealer/retailer or a
qualified technician service them.
The vehicle may have HID headlamps. After an HIDheadlamp bulb has been replaced, you may notice thatthe beam is a slightly different shade than it wasoriginally. This is normal.

Your vehicle has also been equipped with a TPMSmalfunction indicator to indicate when the system is notoperating properly. The TPMS malfunction indicatoris combined with the low tire pressure telltale. When thesystem detects a malfunction, the telltale will flash forapproximately one minute and then remain continuouslyilluminated. This sequence will continue uponsubsequent vehicle start-ups as long as themalfunction exists.
When the malfunction indicator is illuminated, thesystem may not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occur fora variety of reasons, including the installation ofreplacement or alternate tires or wheels on the vehiclethat prevent the TPMS from functioning properly.Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on your vehicle toensure that the replacement or alternate tires andwheels allow the TPMS to continue to function properly.
SeeTire Pressure Monitor Operation on page 6-58for additional information.

Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System(TPMS). The TPMS is designed to warn the driverwhen a low tire pressure condition exists. TPMS sensorsare mounted onto each tire and wheel assembly,excluding the spare tire and wheel assembly. The TPMSsensors monitor the air pressure in the vehicle’s tiresand transmits the tire pressure readings to a receiverlocated in the vehicle.
When a low tire pressurecondition is detected, theTPMS illuminates thelow tire pressure warninglight located on theinstrument panel cluster.
6-58

At the same time a message to check the pressure in aspecific tire appears on the Driver Information Center(DIC) display. The low tire pressure warning lightand the DIC warning message come on at each ignitioncycle until the tires are inflated to the correct inflationpressure. Using the DIC, tire pressure levels canbe viewed by the driver. For additional information anddetails about the DIC operation and displays seeDIC Operation and Displays on page 4-62andDICWarnings and Messages on page 4-67.
The low tire pressure warning light may come on in coolweather when the vehicle is first started, and thenturn off as you start to drive. This could be an earlyindicator that the air pressure in the tire(s) are gettinglow and need to be inflated to the proper pressure.
A Tire and Loading Information label, attached to yourvehicle, shows the size of your vehicle’s originalequipment tires and the correct inflation pressure foryour vehicle’s tires when they are cold. SeeLoading theVehicle on page 5-18, for an example of the Tire andLoading Information label and its location on yourvehicle. Also seeInflation - Tire Pressure on page 6-54.
Your vehicle’s TPMS can warn you about a low tirepressure condition but it does not replace normaltire maintenance. SeeTire Inspection and Rotation onpage 6-62andTires on page 6-46.
Notice:Using non-approved tire sealants coulddamage the Tire Pressure Monitor System (TPMS)sensors. TPMS sensor damage caused by usingan incorrect tire sealant is not covered by thevehicle warranty. Always use the GM approved tiresealant available through your dealer/retailer.
Factory-installed Tire Inflator Kits use a GM approvedliquid tire sealant. Using non-approved tire sealantscould damage the TPMS sensors. SeeTire Sealant andCompressor Kit on page 6-71for information regardingthe inflator kit materials and instructions.
TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of theTPMS sensors are missing or inoperable. When thesystem detects a malfunction, the low tire warning lightflashes for about one minute and then stays on forthe remainder of the ignition cycle. A DIC warningmessage is also displayed. The low tire warning lightand DIC warning message come on at each ignitioncycle until the problem is corrected. Some of theconditions that can cause the malfunction light and DICmessage to come on are:
•One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMSsensor. The TPMS malfunction light and DICmessage should go off once you re-install the roadtire containing the TPMS sensor.
6-59

•The TPMS sensor matching process was started
but not completed or not completed successfullyafter rotating the vehicle’s tires. The DIC messageand TPMS malfunction light should go off oncethe TPMS sensor matching process is performedsuccessfully. See “TPMS Sensor Matching Process”later in this section.
•One or more TPMS sensors are missing or
damaged. The DIC message and the TPMSmalfunction light should go off when the TPMSsensors are installed and the sensor matchingprocess is performed successfully. See yourdealer/retailer for service.
•Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels.Tires and wheels other than those recommendedfor your vehicle could prevent the TPMS fromfunctioning properly. SeeBuying New Tires onpage 6-64.
•Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMScould cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or signala low tire condition. See your dealer/retailer forservice if the TPMS malfunction light and DIC messagecomes on and stays on.
TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.Any time you rotate your vehicle’s tires or replace one ormore of the TPMS sensors, the identification codeswill need to be matched to the new tire/wheel position.The sensors are matched to the tire/wheel positionsin the following order: driver side front tire, passengerside front tire, passenger side rear tire, and driverside rear tire using a TPMS diagnostic tool. See yourdealer/retailer for service.
The TPMS sensors can also be matched to eachtire/wheel position by increasing or decreasing the tire’sair pressure. If increasing the tire’s air pressure, donot exceed the maximum inflation pressure indicated onthe tire’s sidewall.
To decrease air-pressure out of a tire you can use thepointed end of the valve cap, a pencil-style air pressuregage, or a key.
You have two minutes to match the first tire/wheelposition, and five minutes overall to match all fourtire/wheel positions. If it takes longer than two minutes,to match the first tire and wheel, or more than fiveminutes to match all four tire and wheel positions thematching process stops and you need to start over.
