2010 CADILLAC DTS warning

Tires
Your new vehicle comes with high-quality tiresmade by a leading tire manufacturer. If you everhave questions about your tire warranty and whereto obtain service, see your vehicle Warrantybooklet for details. For additional information referto the tire manufacturer.
{WARNING:
•Poorly maintained and improperly used
tires are dangerous.
•Overloading your tires can cause
overheating as a result of too muchflexing. You could have an air-out and aserious accident. SeeLoading theVehicle on page 5-18.
WARNING: (Continued)
WARNING: (Continued)
•Underinflated tires pose the same danger
as overloaded tires. The resultingaccident could cause serious injury.Check all tires frequently to maintain therecommended pressure. Tire pressureshould be checked when your tires arecold. SeeInflation - Tire Pressure onpage 6-54.
•Overinflated tires are more likely to be
cut, punctured, or broken by a suddenimpact — such as when you hit apothole. Keep tires at the recommendedpressure.
•Worn, old tires can cause accidents. If
your tread is badly worn, or if your tireshave been damaged, replace them.
SeeHigh-Speed Operation on page 6-56forinflation pressure adjustment for high speeddriving.

Professional Vehicle
The proper inflation of the tires on yourprofessional vehicle depends on the type of tireson it.
•If your vehicle has P235/60R17 size tires, the
cold inflation pressure is 41 psi (284 kPa).
•If your vehicle has LT235/60R17E size tires,
the cold inflation pressure depends on thevehicle mass and should be determined by thevehicle coach-builder. A Tire and LoadingInformation label provided by the final stagemanufacturer should be attached to the B-pillaron the driver’s side of the vehicle. If the finalstage manufacturer’s label is not present,the coach-builder should be consulted. Do notuse the tire pressures indicated on theGeneral Motors label. These tire pressures arefor the incomplete vehicle and are not thecorrect tire pressures for the completedprofessional vehicle.
Operation at inflation pressures below thisrecommendation may cause your tires to becomeoverloaded.
High-Speed Operation
{WARNING:
Driving at high speeds, 160 km/h (100 mph) or
higher, puts an additional strain on tires. Sustained
high-speed driving causes excessive heat build up
and can cause sudden tire failure. You could have
a crash and you or others could be killed. Some
high-speed rated tires require inflation pressure
adjustment for high speed operation. When speed
limits and road conditions are such that a vehicle
can be driven at high speeds, make sure the tires
are rated for high speed operation, in excellent
condition, and set to the correct cold tire inflation
pressure for the vehicle load.

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

A five-tire rotation pattern may be used for yourprofessional vehicle, if it has a full-size sparetire and wheel assembly that matches the originalequipment tires and wheels in size, type andbrand. The correct five-tire rotation patternis shown.
After the tires have been rotated, adjust the frontand rear inflation pressures as shown on theTire and Loading Information label. SeeLoadingthe Vehicle on page 5-18.
Vehicles that have the Tire Pressure MonitorSystem (TPMS) will need to have the sensorsreset after a tire rotation is performed. SeeTire Pressure Monitor System on page 6-57.
Make certain that all wheel nuts are properlytightened. See “Wheel Nut Torque” underCapacities and Specifications on page 6-109.
{WARNING:
Rust or dirt on a wheel, or on the parts towhich it is fastened, can make wheel nutsbecome loose after time. The wheel couldcome off and cause an accident. When youchange a wheel, remove any rust or dirt fromplaces where the wheel attaches to thevehicle. In an emergency, you can use acloth or a paper towel to do this; but be sureto use a scraper or wire brush later, ifneeded, to get all the rust or dirt off. SeeChanging a Flat Tire on page 6-80.
6-63

GM’s exclusive TPC Spec system considers over adozen critical specifications that impact the overallperformance of your vehicle, including brake systemperformance, ride and handling, traction control, and tirepressure monitoring performance. GM’s TPC Specnumber is molded onto the tire’s sidewall near the tiresize. If the tires have an all-season tread design,the TPC Spec number will be followed by an MS formud and snow. SeeTire Sidewall Labeling on page 6-47for additional information.
GM recommends replacing tires in sets of four. This isbecause uniform tread depth on all tires will helpkeep your vehicle performing most like it did when thetires were new. Replacing less than a full set of tires canaffect the braking and handling performance of yourvehicle. SeeTire Inspection and Rotation on page 6-62for information on proper tire rotation.
{WARNING:
Mixing tires could cause you to lose control of
your vehicle while driving. If you mix tires of
different sizes, brands, or types (radial and
bias-belted tires), the vehicle may not handle
properly, and you could have a crash. Using tires
of different sizes, brands, or types may also cause
damage to your vehicle. Be sure to use the correct
size, brand, and type of tires on all wheels.
Your vehicle may have a compact spare tire and
wheel assembly. If the vehicle has a compact
spare tire and wheel, they have the same overall
diameter as your vehicle’s full-size tires and
wheels. Because they were designed and
developed for use on your vehicle, it is all right to
drive your vehicle with the compact spare installed
properly. Compact spare tires are designed for
temporary use only. SeeSpare Tire on page 6-90.
6-65

{WARNING:
If you use bias-ply tires on the vehicle, thewheel rim flanges could develop cracks aftermany miles of driving. A tire and/or wheelcould fail suddenly, causing a crash. Useonly radial-ply tires with the wheels onthe vehicle.
If you must replace your vehicle’s tires with those thatdo not have a TPC Spec number, make sure theyare the same size, load range, speed rating, andconstruction type (radial and bias-belted tires) as yourvehicle’s original tires.
Vehicles that have a tire pressure monitoring systemcould give an inaccurate low-pressure warning ifnon-TPC Spec rated tires are installed on your vehicle.Non-TPC Spec rated tires may give a low-pressurewarning that is higher or lower than the proper warninglevel you would get with TPC Spec rated tires. SeeTire Pressure Monitor System on page 6-57.
Your vehicle’s original equipment tires are listed on theTire and Loading Information Label. SeeLoadingthe Vehicle on page 5-18, for more information aboutthe Tire and Loading Information Label and its locationon your vehicle.
Different Size Tires and Wheels
If you add wheels or tires that are a different size thanyour original equipment wheels and tires, this mayaffect the way your vehicle performs, including itsbraking, ride and handling characteristics, stability, andresistance to rollover. Additionally, if your vehiclehas electronic systems such as, antilock brakes, tractioncontrol, and electronic stability control, the performanceof these systems can be affected.
{WARNING:
If you add different sized wheels, your vehicle may
not provide an acceptable level of performance
and safety if tires not recommended for those
wheels are selected. You may increase the
chance that you will crash and suffer serious
injury. Only use GM specific wheel and tire
systems developed for your vehicle, and have
them properly installed by a GM certified
technician.
SeeBuying New Tires on page 6-64andAccessoriesand Modifications on page 6-3for additional information.
6-66

If you need to replace any of your wheels, wheel bolts,wheel nuts, or Tire Pressure Monitor System (TPMS)sensors, replace them only with new GM originalequipment parts. This way, you will be sure to have theright wheel, wheel bolts, wheel nuts, and TPMSsensors for your vehicle.
{WARNING:
Using the wrong replacement wheels, wheel bolts,
or wheel nuts on your vehicle can be dangerous. It
could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts, and wheel nuts for
replacement.
Notice:The wrong wheel can also cause problemswith bearing life, brake cooling, speedometer orodometer calibration, headlamp aim, bumper height,vehicle ground clearance, and tire or tire chainclearance to the body and chassis.
If your vehicle is a professional model, the wheels havea unique offset and bolt hole diameter. Each of thewheels on the professional vehicle have eight wheelsnuts. The wheels on the non-professional vehiclehave five wheel nuts. SeeChanging a Flat Tire onpage 6-80for more information.
Used Replacement Wheels
{WARNING:
Putting a used wheel on the vehicle is dangerous.
You cannot know how it has been used or how far
it has been driven. It could fail suddenly and
cause a crash. If you have to replace a wheel, use
a new GM original equipment wheel.
