service indicator CADILLAC DTS 2010 1.G User Guide

The TCS/StabiliTrak warning light on the instrumentpanel cluster will flash when the system is operating.SeeTraction Control System (TCS) Warning Lighton page 4-54andStabiliTrak®Indicator Light onpage 4-54for more information. The system may beheard or felt while it is working. This is normal.
The SERVICE STABILITRAK message is displayed andthe TCS/StabiliTrak warning light on the instrumentpanel cluster comes on if there is a problem with thesystem. When this light and the SERVICESTABILITRAK message are on, the system is notworking. Adjust your driving accordingly.
Traction Control System (TCS)
The vehicle has a Traction Control System (TCS) thatlimits wheel spin. This is especially useful in slippery roadconditions. The system operates only if it senses that thefront wheels are spinning too much or beginning to losetraction. When this happens, the system works the frontbrakes and reduces engine power (by closing the throttleand managing engine spark) to limit wheel spin.
The TCS and StabiliTrak®
light will flash when thesystem is limitingwheel spin.
The system may be heard or felt while it is working, butthis is normal. SeeTraction Control System (TCS)Warning Light on page 4-54for more information.
If the vehicle is in cruise control when TCS begins tolimit wheel spin, the cruise control will automaticallydisengage. The cruise control may be re-engaged whenroad conditions allow. SeeCruise Control on page 4-12.
The SERVICE TRACTION CONTROL message inthe DIC and the TCS/StabiliTrak warning light comes onif there is a problem with the traction control system.SeeDIC Warnings and Messages on page 4-67.
When this light and the SERVICE TRACTIONCONTROL message are on, the system will not limitwheel spin. Adjust your driving accordingly.

If this occurs, use a gasoline rated at 87 octane orhigher as soon as possible. Otherwise, you coulddamage the engine. If heavy knocking is heard whenusing gasoline rated at 87 octane or higher, the engineneeds service.
Gasoline Specifications
At a minimum, gasoline should meet ASTM specificationD 4814 in the United States or CAN/CGSB-3.5 or3.511 in Canada. Some gasolines contain anoctane-enhancing additive called methylcyclopentadienylmanganese tricarbonyl (MMT). We recommendagainst the use of gasolines containing MMT. SeeAdditives on page 6-6for additional information.
California Fuel
If the vehicle is certified to meet California EmissionsStandards, it is designed to operate on fuels thatmeet California specifications. See the underhoodemission control label. If this fuel is not availablein states adopting California emissions standards, thevehicle will operate satisfactorily on fuels meeting federalspecifications, but emission control system performancemight be affected. The malfunction indicator lampcould turn on and the vehicle might fail asmog-check test.
SeeMalfunction Indicator Lamp on page 4-57. If thisoccurs, return to your authorized dealer/retailer fordiagnosis. If it is determined that the condition is causedby the type of fuel used, repairs might not be coveredby the vehicle warranty.
Additives
To provide cleaner air, all gasolines in the United Statesare now required to contain additives that help preventengine and fuel system deposits from forming, allowingthe emission control system to work properly. In mostcases, nothing should have to be added to the fuel.However, some gasolines contain only the minimumamount of additive required to meet U.S. EnvironmentalProtection Agency regulations. To help keep fuel injectorsand intake valves clean, or if the vehicle experiencesproblems due to dirty injectors or valves, look for gasolinethat is advertised as TOP TIER Detergent Gasoline.
For customers who do not use TOP TIER DetergentGasoline regularly, one bottle of GM Fuel SystemTreatment PLUS, added to the fuel tank at everyengine oil change, can help clean deposits from fuelinjectors and intake valves. GM Fuel System TreatmentPLUS is the only gasoline additive recommended byGeneral Motors.
Also, your dealer/retailer has additives that will helpcorrect and prevent most deposit-related problems.

Gasolines containing oxygenates, such as ethers andethanol, and reformulated gasolines might be availablein your area. We recommend that you use thesegasolines, if they comply with the specificationsdescribed earlier. However, E85 (85% ethanol) andother fuels containing more than 10% ethanol mustnot be used in vehicles that were not designed forthose fuels.
Notice:This vehicle was not designed for fuel thatcontains methanol. Do not use fuel containingmethanol. It can corrode metal parts in the fuelsystem and also damage plastic and rubber parts.That damage would not be covered under thevehicle warranty.
Some gasolines that are not reformulated for lowemissions can contain an octane-enhancing additivecalled methylcyclopentadienyl manganese tricarbonyl(MMT); ask the attendant where you buy gasolinewhether the fuel contains MMT. We recommend againstthe use of such gasolines.
Fuels containing MMT can reduce the life of spark plugsand the performance of the emission control systemcould be affected. The malfunction indicator lamp mightturn on. If this occurs, return to your dealer/retailer forservice.
Fuels in Foreign Countries
If you plan on driving in another country outside theUnited States or Canada, the proper fuel might be hardto find. Never use leaded gasoline or any other fuelnot recommended in the previous text on fuel. Costlyrepairs caused by use of improper fuel would notbe covered by the vehicle warranty.
To check the fuel availability, ask an auto club, orcontact a major oil company that does business in thecountry where you will be driving.

{WARNING:
With the wrong kind of fluid in the brake hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake fluid.
Notice:
•Using the wrong fluid can badly damage brake
hydraulic system parts. For example, just afew drops of mineral-based oil, such as engineoil, in the brake hydraulic system can damagebrake hydraulic system parts so badly that theywill have to be replaced. Do not let someoneput in the wrong kind of fluid.
•If brake fluid is spilled on the vehicle’s painted
surfaces, the paint finish can be damaged. Becareful not to spill brake fluid on the vehicle.If you do, wash it off immediately. SeeWashingYour Vehicle on page 6-95.
Brake Wear
This vehicle has disc brakes. Disc brake pads havebuilt-in wear indicators that make a high-pitched warningsound when the brake pads are worn and new padsare needed. The sound can come and go or be heard allthe time the vehicle is moving, except when applyingthe brake pedal firmly.
{WARNING:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to an
accident. When the brake wear warning sound is
heard, have the vehicle serviced.
Notice:Continuing to drive with worn-out brakepads could result in costly brake repair.
Some driving conditions or climates can cause a brakesqueal when the brakes are first applied or lightlyapplied. This does not mean something is wrong withthe brakes.
