It is recommended that the two fronttires or two rear tires generally bereplaced as a pair.
The tire pressure sensors mounted inthe wheels (originally installed on yourvehicle) are not designed to be used inaftermarket wheels.
The use of wheels or tires notrecommended by Ford Motor Companymay affect the operation of your tirepressure monitoring system.
If the tire pressure monitoring systemindicator is flashing, your system ismalfunctioning. Your replacement tiremight be incompatible with your tirepressure monitoring system, or somecomponent of the system may bedamaged.
Safety Practices
WARNING: If your vehicle is stuckin snow, mud or sand, do not rapidlyspin the tires; spinning the tires cantear the tire and cause an explosion.A tire can explode in as little as threeto five seconds.
WARNING: Do not spin thewheels at over 34 mph (55 km/h). Thetires may fail and injure a passengeror bystander.
Driving habits have a great deal to dowith your tire mileage and safety.
*Observe posted speed limits
*Avoid fast starts, stops and turns
*Avoid potholes and objects on the road
*Do not run over curbs or hit the tireagainst a curb when parking
Highway Hazards
No matter how carefully you drive, thereis always the possibility that you mayeventually have a flat tire on thehighway. Drive slowly to the closest safearea out of traffic. This may furtherdamage the flat tire, but your safety ismore important.
If you feel a sudden vibration or ridedisturbance while driving, or you suspectyour tire or vehicle has been damaged,immediately reduce your speed. Drivewith caution until you can safely pull offthe road. Stop and inspect the tires fordamage. If a tire is under-inflated ordamaged, deflate it, remove wheel andreplace it with your spare tire and wheel.If you cannot detect a cause, have the
vehicle towed to the nearest repairfacility or tire dealer to have the vehicleinspected.

TIRE PRESSURE MONITORING
SYSTEM
WARNING: The tire pressuremonitoring system is not a substitute formanually checking tire pressures. Youshould periodically check tire pressuresusing a pressure gauge. Failure to correctlymaintain tire pressures could increase therisk of tire failure, loss of control, vehiclerollover and personal injury.
Note: You should only use tire sealants inroadside emergencies as they may causedamage to the tire pressure monitoringsystem sensor.
Note: If the tire pressure monitoring systemsensor becomes damaged, it may notfunction.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommended by thevehicle manufacturer on the vehicle placardor tire inflation pressure label. (If your vehiclehas tires of a different size than the sizeindicated on the vehicle placard or tireinflation pressure label, you shoulddetermine the proper tire inflation pressurefor those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver’s responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination ofthe TPMS low tire pressure telltale.
Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe system is not operating properly. TheTPMS malfunction indicator is combined withthe low tire pressure telltale. When thesystem detects a malfunction, the telltale willflash for approximately one minute and thenremain continuously illuminated. Thissequence will continue upon subsequentvehicle start-ups as long as the malfunctionexists.
When the malfunction indicator is illuminated,the system may not be able to detect orsignal low tire pressure as intended. TPMSmalfunctions may occur for a variety ofreasons, including the installation ofreplacement or alternate tires or wheels onthe vehicle that prevent the TPMS from

functioning properly. Always check the TPMSmalfunction telltale after replacing one ormore tires or wheels on your vehicle toensure that the replacement or alternate tiresand wheels allow the TPMS to continue tofunction properly.
This device complies with Part 15 of the FCCRules and with Licence exempt RSSStandards of Industry Canada. Operation issubject to the following two conditions:
1. This device may not cause harmfulinterference, and
2.This device must accept any interferencereceived, including interference that maycause undesired operation.
WARNING: Changes or modificationsnot expressively approved by the partyresponsible for compliance could void theuser's authority to operate the equipment.The term "IC:" before the radio certificationnumber only signifies that Industry Canadatechnical specifications were met.
Changing Tires With a Tire PressureMonitoring System
Note:Each road tire is equipped with a tirepressure sensor located inside the wheeland tire assembly cavity. The pressuresensor is attached to the valve stem. Thepressure sensor is covered by the tire andis not visible unless the tire is removed. Takecare when changing the tire to avoiddamaging the sensor.
You should always have your tires servicedby an authorized dealer.
Check the tire pressure periodically (at leastmonthly) using an accurate tire gauge. SeeInflating Your Tires in this chapter.
Understanding Your Tire PressureMonitoring System
The tire pressure monitoring systemmeasures pressure in your four road tiresand sends the tire pressure readings to yourvehicle. The low tire pressure warning lightwill turn on if the tire pressure is significantlylow. Once the light is illuminated, your tiresare under-inflated and need to be inflated tothe manufacturer’s recommended tirepressure. Even if the light turns on and ashort time later turns off, your tire pressurestill needs to be checked.
When Your Temporary Spare Tire isInstalled
When one of your road tires needs to bereplaced with the temporary spare, thesystem will continue to identify an issue toremind you that the damaged road wheeland tire assembly needs to be repaired andput back on your vehicle.

When Inflating Your Tires
When putting air into your tires (such as at agas station or in your garage), the tirepressure monitoring system may not respondimmediately to the air added to your tires.
It may take up to two minutes of driving over20 mph (32 km/h) for the light to turn off afteryou have filled your tires to therecommended inflation pressure.
How Temperature Affects Your TirePressure
The tire pressure monitoring system monitorstire pressure in each pneumatic tire. Whiledriving in a normal manner, a typicalpassenger tire inflation pressure mayincrease about 2–4 psi (14–28 kPa) from acold start situation. If the vehicle is stationaryovernight with the outside temperaturesignificantly lower than the daytimetemperature, the tire pressure may decreaseabout 3 psi (21 kPa) for a drop of 30°F (17°C)in ambient temperature. This lower pressurevalue may be detected by the tire pressuremonitoring system as being significantlylower than the recommended inflation
pressure and activate the system warninglight for low tire pressure. If the low tirepressure warning light is on, visually checkeach tire to verify that no tire is flat. If one ormore tires are flat, repair as necessary.Check the air pressure in the road tires. Ifany tire is under-inflated, carefully drive thevehicle to the nearest location where air canbe added to the tires. Inflate all the tires tothe recommended inflation pressure.
CHANGING A ROAD WHEEL
WARNING: Do not use tire sealantsas they may damage the tire pressuremonitoring system.
WARNING: If the tire pressuremonitor sensor becomes damaged it maynot function.
Note:The tire pressure monitoring systemindicator light will illuminate when the sparetire is in use. To restore the full function ofthe monitoring system, all road wheelsequipped with tire pressure monitoringsensors must be mounted on the vehicle.
Note:If your vehicle is equipped with theoptional 5th road wheel and tire assembly,the storage location in the luggagecompartment is for temporary use only. Theoptional full size road wheel and tireassembly should be stored outside thevehicle after delivery.
If you get a flat tire while driving, do not applythe brake heavily. Instead, graduallydecrease your speed. Hold the steeringwheel firmly and slowly move to a safe placeon the side of the road.
