TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
Tire Quality Grades apply to newpneumatic passenger car tires.The Quality grades can be foundwhere applicable on the tiresidewall between tread shoulderand maximum section width. Forexample: Treadwear 200Traction AA Temperature A.
These Tire Quality Grades aredetermined by standards that theUnited States Department ofTransportation has set.
Tire Quality Grades apply to newpneumatic passenger car tires.They do not apply to deep tread,winter-type snow tires,space-saver or temporary usespare tires, light truck or LT typetires, tires with nominal rimdiameters of 10 to 12 inches orlimited production tires as definedin Title 49 Code of FederalRegulations Part 575.104 (c)(2).
U.S. Department ofTransportation Tire qualitygrades: The U.S. Department ofTransportation requires us to giveyou the following informationabout tire grades exactly as thegovernment has written it.
Treadwear
The treadwear grade is acomparative rating based on thewear rate of the tire when testedunder controlled conditions on aspecified government test course.For example, a tire graded 150would wear 1½ times as well onthe government course as a tiregraded 100. The relativeperformance of tires dependsupon the actual conditions of theiruse, however, and may departsignificantly from the norm due tovariations in driving habits, servicepractices, and differences in roadcharacteristics and climate.

Traction AA A B C
WARNING: The tractiongrade assigned to this tire isbased on straight-ahead brakingtraction tests, and does notinclude acceleration, cornering,hydroplaning or peak tractioncharacteristics.
The traction grades, from highestto lowest are AA, A, B, and C. Thegrades represent the tire’s abilityto stop on wet pavement asmeasured under controlledconditions on specifiedgovernment test surfaces ofasphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING: Thetemperature grade for this tire isestablished for a tire that isproperly inflated and notoverloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heatbuildup and possible tire failure.
The temperature grades are A(the highest), B and C,representing the tire’s resistanceto the generation of heat and itsability to dissipate heat when
tested under controlled conditionson a specified indoor laboratory
test wheel. Sustained hightemperature can cause thematerial of the tire to degenerateand reduce tire life, and excessivetemperature can lead to suddentire failure. The grade Ccorresponds to a level ofperformance which all passengercar tires must meet under theFederal Motor Vehicle SafetyStandard No. 139. Grades B and Arepresent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law.
INFORMATION ON THE TIRE
SIDEWALL
Both United States and CanadaFederal regulations require tiremanufacturers to placestandardized information on thesidewall of all tires. Thisinformation identifies anddescribes the fundamentalcharacteristics of the tire and alsoprovides a U.S. DOT TireIdentification Number for safetystandard certification and in caseof a recall.

Rotating your tires at therecommended interval, asindicated in the scheduledmaintenance chapter, will helpyour tires wear more evenly,providing better tire performanceand longer tire life.
For the best tire life, a five tirerotation is recommended thatincludes the matching spare tiremounted on the back of thevehicle. This rotation requires aforced re-learning of your tirepressure monitor system sensorsby your vehicle, and should beperformed by an authorized dealeror a service center to make surethe tire pressure monitoringsystem provides proper warningat all times. When performing thetire rotation yourself, a four tirerotation is recommended, withoutusing the spare tire in the rotation,so that no tire pressure monitorsystem sensor re-learn is required.If a five tire rotation is performedwithout a tire pressure monitorsystem sensor re-learn, thesystem may not provide a low tirepressure warning when necessary.
Keep in mind that a spare tire thatis not used in the tire rotationshould only be used temporarilyin the event of a flat tire, not as apermanent replacement. Thespare tire should always bereplaced if it exceeds 6 years ofage, regardless of whether it ispart of the tire rotation.
Rear-wheel drive vehicles andfour-wheel drive vehicles with fourtire rotation, front tires at left ofdiagram.
Sometimes irregular tire wear canbe corrected by rotating the tires.

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
Tire Pressure Monitoring System withIndividual Tire Pressure Display
The tire pressure monitoringsystem measures the vehicle'stire pressures. A warning lampilluminates if one or more tires aresignificantly underinflated or if there is asystem malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW
WARNING: Under-inflation is themost common cause of tire failures andmay result in severe tire cracking, treadseparation or blowout, with unexpectedloss of vehicle control and increased riskof injury. Under-inflation increasessidewall flexing and rolling resistance,resulting in heat buildup and internaldamage to the tire. It also may result inunnecessary tire stress, irregular wear,loss of vehicle control and accidents. Atire can lose up to half of its air pressureand not appear to be flat!
WARNING: To determine therequired pressure(s) for your vehicle, seethe Safety Compliance CertificationLabel (on the door hinge pillar,door-latch post or the door edge thatmeets the door-latch post, next to thedriver seat) or the Tire Label on theB-Pillar or the edge of the driver door.
Each tire, including the spare (if provided),should be checked monthly when cold andinflated to the inflation pressurerecommended by the vehicle manufactureron the vehicle placard or tire inflationpressure label. (If your vehicle has tires ofa different size than the size indicated onthe vehicle placard or tire inflation pressurelabel, you should determine the proper tireinflation pressure for those tires).
As an added safety feature, your vehiclehas been equipped with a Tire PressureMonitoring System (TPMS) thatilluminates a low tire pressure telltalewhen one or more of your tires issignificantly under-inflated. Accordingly,when the low tire pressure telltaleilluminates, you should stop and checkyour tires as soon as possible, and inflatethem to the proper pressure. Driving on asignificantly under-inflated tire causes thetire to overheat and can lead to tire failure.Under-inflation also reduces fuel efficiencyand tire tread life, and may affect thevehicle’s handling and stopping ability.
Please note that the TPMS is not asubstitute for proper tire maintenance, andit is the driver’s responsibility to maintaincorrect tire pressure, even if under-inflationhas not reached the level to triggerillumination of the TPMS low tire pressuretelltale.
Your vehicle has also been equipped witha TPMS malfunction indicator to indicatewhen the system is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and then remaincontinuously illuminated. This sequencewill continue upon subsequent vehiclestart-ups as long as the malfunction exists.

2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMTire Pressure Monitoring SystemE139232

When the malfunction indicator isilluminated, the system may not be ableto detect or signal low tire pressure asintended. TPMS malfunctions may occurfor a variety of reasons, including theinstallation of replacement or alternatetires or wheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or more tires orwheels on your vehicle to ensure that thereplacement or alternate tires and wheelsallow the TPMS to continue to functionproperly.

TIRE PRESSURE MONITORING
SYSTEM PRECAUTIONS
WARNING: The tire pressuremonitoring system is not a substitute formanually checking tire pressures. Youshould periodically check tire pressuresusing a pressure gauge. Failure tocorrectly maintain tire pressures couldincrease the risk of tire failure, loss ofcontrol, vehicle rollover and personalinjury.
WARNING: Do not use the tirepressure displayed in the informationdisplay as a tire pressure gauge. Failureto follow this instruction could result inpersonal injury or death.
Note:The use of tire sealants can damagethe tire pressure monitoring system.
Note:If the tire pressure monitor sensorbecomes damaged it may not function.
TIRE PRESSURE MONITORING
SYSTEM LIMITATIONS
When the outside temperature dropssignificantly, the tire pressure coulddecrease and activate the low tire pressurewarning lamp.
The warning lamp could also illuminatewhen you use a spare wheel, or tire sealantfrom the inflator kit.
Note:Regularly checking the vehicle tirepressures can reduce the possibility for thewarning lamp to illuminate due to outsideair temperature changes.
Note:After you inflate the tires to therecommended pressure it could take up totwo minutes of driving over 20 mph(32 km/h) for the warning indicator to turnoff.

HD Radio Technology is manufacturedunder license from iBiquity DigitalCorporation and foreign patents. HD Radioand the HD and HD Radio logos areproprietary trademarks of XPERI. Thevehicle manufacturer and XPERI are notresponsible for the content sent using HDRadio technology. Content may bechanged, added or deleted at any time atthe station owner's discretion.
HOW DOES DIGITAL RADIO WORK
Your system has a special receiver thatallows it to receive digital broadcasts inaddition to analog broadcasts.
HD1 signifies the main programming statusand is available in both analog and digitalbroadcasts. Other multicast stations areonly available digitally and could containnew or different content.
Note:When the system first receives anHD1 station, it plays the station in the analogversion until it verifies the station is an HDRadio station. Then it shifts to the digitalversion.
Note:There is an audio mute delay whenswitching to an HD2 or HD3 station becausethe system has to reacquire and decode thedigital signal.
DIGITAL RADIO LIMITATIONS
If you are outside the reception area, thesystem could not work.
If you are on the fringe of the receptionarea, the station could mute due to weaksignal strength.
Note:If you are listening to HD1, the systemchanges back to the analog broadcast untilthe digital broadcast is available again. Ifyou are listening to any other multicastchannels, the station mutes and staysmuted unless it is able to connect to thedigital signal again.
