2018 FORD FOCUS Owners Manual

Inspecting Your Tires andWheel Valve Stems
Periodically inspect the tire treadsfor uneven or excessive wear andremove objects such as stones,nails or glass that may be wedgedin the tread grooves. Check the tireand valve stems for holes, cracks,or cuts that may permit airleakage and repair or replace thetire and replace the valve stem.Inspect the tire sidewalls forcracking, cuts, bruises and othersigns of damage or excessivewear. If internal damage to the tireis suspected, have the tiredemounted and inspected in caseit needs to be repaired or replaced.For your safety, tires that aredamaged or show signs ofexcessive wear should not be usedbecause they are more likely toblow out or fail.
Improper or inadequate vehiclemaintenance can cause tires towear abnormally. Inspect all yourtires, including the spare,frequently, and replace them ifone or more of the followingconditions exist:
Tire Wear
When the tread is worn down to1/16th of an inch (2 mm), tiresmust be replaced to help preventyour vehicle from skidding andhydroplaning. Built-in treadwearindicators, or wear bars, whichlook like narrow strips of smoothrubber across the tread willappear on the tire when the treadis worn down to 1/16th of an inch(2 mm).
When the tire tread wears downto the same height as these wearbars, the tire is worn out and mustbe replaced.
Damage
Periodically inspect the tire treadsand sidewalls for damage (suchas bulges in the tread or sidewalls,cracks in the tread groove andseparation in the tread orsidewall). If damage is observed

or suspected have the tireinspected by a tire professional.Tires can be damaged duringoff-road use, so inspection afteroff-road use is alsorecommended.
Age
WARNING
Tires degrade over timedepending on many factorssuch as weather, storageconditions, and conditions of use(load, speed, inflation pressure)the tires experience throughouttheir lives.
In general, tires should bereplaced after six years regardlessof tread wear. However, heat
caused by hot climates orfrequent high loading conditionscan accelerate the aging processand may require tires to bereplaced more frequently.
You should replace your spare tirewhen you replace the road tires orafter six years due to aging even ifit has not been used.
U.S. DOT Tire IdentificationNumber
Both United States and CanadaFederal regulations require tiremanufacturers to placestandardized information on thesidewall of all tires. Thisinformation identifies and
describes the fundamentalcharacteristics of the tire and alsoprovides a United States DOT TireIdentification Number for safetystandard certification and in caseof a recall.
This begins with the letters DOTand indicates that the tire meetsall federal standards. The nexttwo numbers or letters are theplant code designating where itwas manufactured, the next twoare the tire size code and the lastfour numbers represent the weekand year the tire was built. Forexample, the numbers 317 meanthe 31st week of 1997. After 2000the numbers go to four digits. Forexample, 2501 means the 25thweek of 2001. The numbers inbetween are identification codesused for traceability. Thisinformation is used to contactcustomers if a tire defect requiresa recall.
Tire ReplacementRequirements
Your vehicle is equipped with tiresdesigned to provide a safe rideand handling capability.
WARNINGS
Only use replacement tiresand wheels that are the samesize, load index, speed rating andtype (such as P-metric versusLT-metric or all-season versusall-terrain) as those originallyprovided by Ford. Therecommended tire and wheel size

WARNINGS
may be found on either the SafetyCompliance Certification Label(affixed to either the door hingepillar, door-latch post, or the dooredge that meets the door-latchpost, next to the driver's seatingposition), or the Tire Label whichis located on the B-Pillar or edgeof the driver's door. If thisinformation is not found on theselabels, then you should contactyour authorized dealer as soon aspossible. Use of any tire or wheelnot recommended by Ford canaffect the safety and performanceof your vehicle, which could resultin an increased risk of loss ofvehicle control, vehicle rollover,personal injury and death.
To reduce the risk of seriousinjury, when mountingreplacement tires and wheels, youshould not exceed the maximumpressure indicated on the sidewallof the tire to set the beads withoutadditional precautions listedbelow. If the beads do not seat atthe maximum pressure indicated,re-lubricate and try again.
When inflating the tire formounting pressures up to20 psi (1.38 bar) greater than themaximum pressure on the tiresidewall, the followingprecautions must be taken toprotect the person mounting thetire:
•Make sure that you have thecorrect tire and wheel size.
•Lubricate the tire bead andwheel bead seat area again.
•Stand at a minimum of 12 ft(3.66 m) away from the wheeland tire assembly.
•Use both eye and earprotection.
WARNINGS
For a mounting pressuremore than 20 psi (1.38 bar)greater than the maximumpressure, a Ford dealer or othertire service professional should dothe mounting.
Always inflate steel carcasstires with a remote air fill withthe person inflating standing at aminimum of 12 ft (3.66 m) awayfrom the wheel and tire assembly.
Important: Remember to replacethe wheel valve stems when theroad tires are replaced on yourvehicle.
It is recommended that the twofront tires or two rear tiresgenerally be replaced as a pair.
The tire pressure sensors mountedin the wheels (originally installedon your vehicle) are not designedto be used in aftermarket wheels.
2562018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingWheels and Tires

The use of wheels or tires notrecommended by Ford MotorCompany may affect theoperation of your tire pressuremonitoring system.
If the tire pressure monitoringsystem indicator is flashing, yourtire pressure monitoring system ismalfunctioning. Your replacementtire might be incompatible withyour TPMS, or some componentof the TPMS may be damaged.
Safety Practices
WARNINGS
If your vehicle is stuck insnow, mud or sand, do notrapidly spin the tires; spinning thetires can tear the tire and causean explosion. A tire can explode in
as little as three to five seconds.
Do not spin the wheels atover 34 mph (55 km/h). Thetires may fail and injure apassenger or bystander.
Driving habits have a great dealto do with your tire mileage andsafety.
Observe posted speed limits.
Avoid fast starts, stops and turns.
Avoid potholes and objects on theroad.
Do not run over curbs or hit the tireagainst a curb when parking.
Highway Hazards
No matter how carefully you drivethere is always the possibility thatyou may eventually have a flat tireon the highway. Drive slowly to theclosest safe area out of traffic.This may further damage the flattire, but your safety is moreimportant.
If you feel a sudden vibration orride disturbance while driving, oryou suspect your tire or vehiclehas been damaged, immediatelyreduce your speed. Drive withcaution until you can safely pulloff the road. Stop and inspect thetires for damage.
If a tire is under-inflated, check thetire for damage. If the tire is notdamaged inflate it to therecommended tire pressure.
If a tire is damaged, have itreplaced immediately. If yourvehicle has a spare wheel, fit thespare wheel immediately andhave the damaged tire replacedas soon as possible. If your vehicledoes not have a spare wheel, haveyour vehicle towed to the nearestrepair facility or tire dealer to havethe tire replaced.

Tire and Wheel Alignment
A bad jolt from hitting a curb orpothole can cause the front endof your vehicle to becomemisaligned or cause damage toyour tires. If your vehicle seems topull to one side when you aredriving, the wheels may be out ofalignment. Have an authorizeddealer check the wheel alignmentperiodically.
Wheel misalignment in the frontor the rear can cause uneven andrapid treadwear of your tires andshould be corrected by anauthorized dealer. Front-wheeldrive vehicles and those with anindependent rear suspension (ifequipped) may require alignmentof all four wheels.
The tires should also be balancedperiodically. An unbalanced tireand wheel assembly may result inirregular tire wear.
Tire Rotation
WARNING
If the tire label showsdifferent tire pressures for thefront and rear tires and the vehiclehas a tire pressure monitoringsystem, then you need to updatethe settings for the systemsensors. Always perform thesystem reset procedure after tirerotation. If you do not reset thesystem, it may not provide a lowtire pressure warning whennecessary.
Note:If your tires show unevenwear ask an authorized dealer tocheck for and correct any wheelmisalignment, tire imbalance ormechanical problem involvedbefore tire rotation.
Note:Your vehicle may beequipped with a dissimilar sparewheel and tire assembly. Adissimilar spare wheel and tireassembly is defined as a sparewheel and tire assembly that isdifferent in brand, size orappearance from the road tires andwheels. If you have a dissimilarspare wheel and tire assembly it isintended for temporary use onlyand should not be used in a tirerotation.
Note:After having your tiresrotated, inflation pressure must bechecked and adjusted to thevehicle requirements.
Rotating your tires at therecommended interval (asindicated in the ScheduledMaintenance chapter) will helpyour tires wear more evenly,providing better tire performanceand longer tire life.
Front-wheel drive vehicles (fronttires on the left side of thediagram).
2582018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingWheels and Tires

Sometimes irregular tire wear canbe corrected by rotating the tires.
USING SNOW CHAINS
WARNING
Snow tires must be the same size,load index and speed rating as thoseoriginally provided by Ford. Use ofany tire or wheel not recommended byFord can affect the safety andperformance of your vehicle, which couldresult in an increased risk of loss of control,vehicle rollover, personal injury and death.Additionally, the use of non-recommendedtires and wheels can cause steering,suspension, axle, transfer case or powertransfer unit failure. Follow the Fordrecommended tire inflation pressure foundon the Safety Compliance CertificationLabel (on the door hinge pillar, door latchpost or the door edge that meets the doorlatch post, next to the driver seat), or TireLabel on the B-Pillar or the edge of thedriver door. Failure to follow the tirepressure recommendations can causeuneven treadwear patterns and adverselyaffect the way your vehicle handles.
The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires or snow chains.
If you choose to install snow tires on yourvehicle, they must be installed on all fourwheels and they must be the same size,load index and speed rating as the originaltires listed on the tire inflation pressurelabel. The label is on the on the B-Pillar orthe edge of the driver door . Mixing tires ofdifferent size or construction on yourvehicle can adversely affect your vehicle’shandling and braking, and may lead to lossof vehicle control.
If you use snow chains, we recommendthat steel wheels of the same size andspecifications are used. Snow chains maydamage aluminum wheels.
Follow these guidelines when using snowchains:
•Avoid fully loading your vehicle.
•Only use small link snow chains ofapproximately 10mm with 215/55R16tires only.
•Only use small link snow chains ofapproximately 15mm with 195/65R15tires only.
•Only use snow chains on the tire sizeslisted above.
•Snow chains must be mounted in pairson the front axle.
•Install snow chains securely, make surethey do not touch any wiring, brakelines or fuel lines.
•Do not exceed 30 mph (48 km/h) orthe maximum speed recommended bythe chain manufacturer, whichever isless.
•Remove snow chains when they are nolonger required.
•Do not use snow chains on dry roads.

TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring systemis not a substitute for manuallychecking tire pressures. You shouldperiodically check tire pressures using apressure 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 inflatedto the inflation pressure recommended bythe vehicle manufacturer on the vehicleplacard or tire inflation pressure label. (Ifyour vehicle has tires of a different sizethan the size indicated on the vehicleplacard or tire inflation pressure label, youshould determine the proper tire inflationpressure 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 inflate
them 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.
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.

Note:Changes or modifications notexpressively 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 TirePressure Monitoring 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 and isnot 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 (atleast monthly) using an accurate tiregauge. See Inflating Your Tires in thischapter.
Understanding Your Tire PressureMonitoring System
The tire pressure monitoring systemmeasures pressure in your four road tiresand sends the tire pressure readings toyour vehicle. The low tire pressure warninglight will turn on if the tire pressure issignificantly low. Once the light isilluminated, your tires are under-inflatedand need to be inflated to themanufacturer’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.
To restore the full function of the tirepressure monitoring system, have thedamaged road wheel and tire assemblyrepaired and remounted on your vehicle.
When You Believe Your System is NotOperating Properly
The main function of the tire pressuremonitoring system is to warn you whenyour tires need air. It can also warn you inthe event the system is no longer capableof functioning as intended. See thefollowing chart for information concerningyour tire pressure monitoring system:
