fuel CADILLAC DTS 2010 1.G Owner's Guide

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.

Filling the Tank
{WARNING:
Fuel vapor burns violently and a fuel fire can
cause bad injuries. To help avoid injuries to you
and others, read and follow all the instructions on
the fuel pump island. Turn off the engine when
refueling. Do not smoke near fuel or when
refueling the vehicle. Do not use cellular phones.
Keep sparks, flames, and smoking materials away
from fuel. Do not leave the fuel pump unattended
when refueling the vehicle. This is against the law
in some places. Do not re-enter the vehicle while
pumping fuel. Keep children away from the fuel
pump; never let children pump fuel.
The tethered fuel cap is located behind a hinged fueldoor on the driver side of the vehicle.
To open the fuel door, push the rearward center edge inand release and it will open.
6-8

To remove the fuel cap, turn it slowly counterclockwise.The fuel cap has a spring in it; if the cap is releasedtoo soon, it will spring back to the right.
While refueling, hang the tethered fuel cap from thehook on the fuel door.
{WARNING:
Fuel can spray out on you if you open the fuel cap
too quickly. If you spill fuel and then something
ignites it, you could be badly burned. This spray
can happen if the tank is nearly full, and is more
likely in hot weather. Open the fuel cap slowly and
wait for any hiss noise to stop. Then unscrew the
cap all the way.
Be careful not to spill fuel. Do not top off or overfill thetank and wait a few seconds after you have finishedpumping before removing the nozzle. Clean fuelfrom painted surfaces as soon as possible. SeeWashing Your Vehicle on page 6-95.
When replacing the fuel cap, turn it clockwise until itclicks. Make sure the cap is fully installed. Thediagnostic system can determine if the fuel cap has
been left off or improperly installed. This would allowfuel to evaporate into the atmosphere. SeeMalfunctionIndicator Lamp on page 4-57.
The TIGHTEN GAS CAP message displays on theDriver Information Center (DIC) if the fuel cap isnot properly installed. SeeDIC Warnings and Messageson page 4-67for more information.
{WARNING:
If a fire starts while you are refueling, do not
remove the nozzle. Shut off the flow of fuel by
shutting off the pump or by notifying the station
attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to getthe right type. Your dealer/retailer can get onefor you. If you get the wrong type, it may not fitproperly. This may cause the malfunction indicatorlamp to light and may damage the fuel tank andemissions system. SeeMalfunction Indicator Lampon page 4-57.
6-9

Filling a Portable Fuel Container
{WARNING:
Never fill a portable fuel container while it is in the
vehicle. Static electricity discharge from the
container can ignite the fuel vapor. You can be
badly burned and the vehicle damaged if this
occurs. To help avoid injury to you and others:
•Dispense fuel only into approved containers.
•Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed, or onany surface other than the ground.
•Bring the fill nozzle in contact with the inside
of the fill opening before operating the nozzle.Contact should be maintained until the fillingis complete.
•Do not smoke while pumping fuel.
•Do not use a cellular phone while
pumping fuel.
Checking Things Under
the Hood
{WARNING:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing, and tools away from any
underhood electric fan.
{WARNING:
Things that burn can get on hot engine parts and
start a fire. These include liquids like fuel, oil,
coolant, brake fluid, windshield washer and other
fluids, and plastic or rubber. You or others could
be burned. Be careful not to drop or spill things
that will burn onto a hot engine.

Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil level at eachfuel fill. In order to get an accurate reading, the oil mustbe warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. SeeEngine Compartment Overview on page 6-12forthe location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutesto drain back into the oil pan. If this is not done, theoil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towelor cloth, then push it back in all the way. Remove itagain, keeping the tip down, and check the level.
6-13

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.

Tire Terminology and Definitions
Air Pressure:The amount of air inside thetire pressing outward on each square inch of thetire. Air pressure is expressed in pounds persquare inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combinedweight of optional accessories. Some examples ofoptional accessories are, automatic transmission,power steering, power brakes, power windows,power seats, and air conditioning.
Aspect Ratio:The relationship of a tire’s heightto its width.
Belt:A rubber coated layer of cords that is locatedbetween the plies and the tread. Cords may bemade from steel or other reinforcing materials.
Bead:The tire bead contains steel wires wrappedby steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the pliesare laid at alternate angles less than 90 degreesto the centerline of the tread.
Cold Tire Pressure:The amount of air pressure ina tire, measured in pounds per square inch (psi) orkilopascals (kPa) before a tire has built up heatfrom driving. SeeInflation - Tire Pressure onpage 6-54.
Curb Weight:The weight of a motor vehicle withstandard and optional equipment including themaximum capacity of fuel, oil, and coolant,but without passengers and cargo.
DOT Markings:A code molded into the sidewallof a tire signifying that the tire is in compliancewith the U.S. Department of Transportation (DOT)motor vehicle safety standards. The DOT codeincludes the Tire Identification Number (TIN),an alphanumeric designator which can also identifythe tire manufacturer, production plant, brand,and date of production.
GVWR:Gross Vehicle Weight Rating. SeeLoading the Vehicle on page 5-18.
GAWR FRT:Gross Axle Weight Rating for thefront axle. SeeLoading the Vehicle on page 5-18.
GAWR RR:Gross Axle Weight Rating for therear axle. SeeLoading the Vehicle on page 5-18.
Intended Outboard Sidewall:The side of anasymmetrical tire, that must always face outwardwhen mounted on a vehicle.
Kilopascal (kPa):The metric unit for air pressure.
Light Truck (LT-Metric) Tire:A tire used onlight duty trucks and some multipurpose passengervehicles.
6-52

Treadwear Indicators:Narrow bands, sometimescalled wear bars, that show across the tread ofa tire when only 1/16 inch (1.6 mm) of treadremains. SeeWhen It Is Time for New Tires onpage 6-64.
UTQGS (Uniform Tire Quality GradingStandards):A tire information system thatprovides consumers with ratings for a tire’straction, temperature, and treadwear. Ratings aredetermined by tire manufacturers usinggovernment testing procedures. The ratings aremolded into the sidewall of the tire. SeeUniformTire Quality Grading on page 6-67.
Vehicle Capacity Weight:The number ofdesignated seating positions multiplied by 150 lbs(68 kg) plus the rated cargo load. SeeLoadingthe Vehicle on page 5-18.
Vehicle Maximum Load on the Tire:Load on anindividual tire due to curb weight, accessoryweight, occupant weight, and cargo weight.
Vehicle Placard:A label permanently attached toa vehicle showing the vehicle’s capacity weightand the original equipment tire size andrecommended inflation pressure. See “Tire andLoading Information Label” underLoadingthe Vehicle on page 5-18.
Inflation - Tire Pressure
Tires need the correct amount of air pressure tooperate effectively.
Notice:Do not let anyone tell you thatunder-inflation or over-inflation is all right. It isnot. If your tires do not have enough air(under-inflation), you can get the following:
•Too much flexing
•Too much heat
•Tire overloading
•Premature or irregular wear
•Poor handling
•Reduced fuel economy
If your tires have too much air (over-inflation),you can get the following:
•Unusual wear
•Poor handling
•Rough ride
•Needless damage from road hazards
6-54

If your vehicle has P235/55R17 or P245/50R18 sizetires, and you will be driving at speeds of 100 mph(160 km/h) or higher, where it is legal, set the coldinflation pressure to the maximum inflation pressureshown on the tire sidewall, or 38 psi (265 kPa),whichever is lower. See the example following.
Example:
You will find the maximum load and inflation pressuremolded on the tire’s sidewall, in small letters, nearthe rim flange. It will read something like this: Maximumload 690 kg (1521 lbs) 300 kPa (44 psi) Max. Press.
For this example, you would set the inflation pressure forhigh-speed driving at 38 psi (265 kPa).
When you end this high-speed driving, return the tires tothe cold inflation pressure shown on the Tire andLoading Information label. SeeLoading the Vehicle onpage 5-18.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radioand sensor technology to check tire pressure levels. TheTPMS sensors monitor the air pressure in yourvehicle’s tires and transmit tire pressure readings to areceiver located in the vehicle.
Each tire, including the spare (if provided), should bechecked monthly when cold and inflated to the inflationpressure recommended by the vehicle manufactureron the vehicle placard or tire inflation pressure label.(If your vehicle has tires of a different size than the sizeindicated on the vehicle placard or tire inflationpressure label, you should determine the proper tireinflation pressure for those tires.)
As an added safety feature, your vehicle has beenequipped with a tire pressure monitoring system (TPMS)that illuminates a low tire pressure telltale when oneor more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltaleilluminates, you should stop and check your tires assoon as possible, and inflate them to the properpressure. Driving on a significantly under-inflated tirecauses the tire to overheat and can lead to tire failure.Under-inflation also reduces fuel efficiency and tiretread life, and may affect the vehicle’s handlingand stopping ability.
Please note that the TPMS is not a substitute for propertire maintenance, and it is the driver’s responsibility tomaintain correct tire pressure, even if under-inflation hasnot reached the level to trigger illumination of theTPMS low tire pressure telltale.

Notice:Driving the vehicle through an automaticcar wash that has silicone carbide tire cleaningbrushes, could damage the aluminum orchrome-plated wheels. The repairs would not becovered by the vehicle warranty. Never drivea vehicle that has aluminum or chrome-platedwheels through an automatic car wash that usessilicone carbide tire cleaning brushes.
Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressingproducts on the vehicle may damage the paint finishand/or tires. When applying a tire dressing, alwayswipe off any overspray from all painted surfaceson the vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metalrepair or replacement, make sure the body repair shopapplies anti-corrosion material to parts repaired orreplaced to restore corrosion protection.
Original manufacturer replacement parts will provide thecorrosion protection while maintaining the vehiclewarranty.
Finish Damage
Any stone chips, fractures or deep scratches in thefinish should be repaired right away. Bare metalwill corrode quickly and may develop into major repairexpense.
Minor chips and scratches can be repaired with touch-upmaterials available from your dealer/retailer. Largerareas of finish damage can be corrected in yourdealer’s/retailer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dustcontrol can collect on the underbody. If these are notremoved, corrosion and rust can develop on theunderbody parts such as fuel lines, frame, floor pan,and exhaust system even though they have corrosionprotection.
At least every spring, flush these materials from theunderbody with plain water. Clean any areas where mudand debris can collect. Dirt packed in close areas ofthe frame should be loosened before being flushed.Your dealer/retailer or an underbody car washing systemcan do this.
