All children are shaped differently.The National Highway Traffic SafetyAdministration and other safetyorganizations, base their recommendationsfor child restraints on probable child height,age and weight thresholds, or on theminimum requirements of the law. Werecommend that you check with a NHTSACertified Child Passenger Safety
WARNINGS
Technician (CPST) to make sure that youproperly install the child restraint in yourvehicle and that you consult yourpediatrician to make sure you have a childrestraint appropriate for your child. Tolocate a child restraint fitting station andCPST, contact NHTSA toll free at1-888-327-4236 or go towww.nhtsa.dot.gov.

Use a child safety restraint (sometimescalled an infant carrier, convertible seat,or toddler seat) for infants, toddlers, orchildren weighing 40 lb (18 kg) or less(generally age four or younger).
Using Lap and Shoulder Belts
WARNINGS
Airbags can kill or injure a child in achild restraint. Never place arear-facing child restraint in front ofan active airbag. If you must use aforward-facing child restraint in the frontseat, move the seat upon which the childrestraint is installed all the way back.
Airbags can kill or injure a child in achild restraint. Properly restrainchildren 12 and under in the rear seatwhenever possible.
Depending on where you secure achild restraint, and depending on thechild restraint design, you may blockaccess to certain seatbelt buckleassemblies and LATCH lower anchors,rendering those features potentiallyunusable. To avoid risk of injury, make sureoccupants only use seating positionswhere they are able to be properlyrestrained.
When installing a child safety restraint withcombination lap and shoulder belts:
•Use the correct seatbelt buckle for thatseating position.
•Insert the belt tongue into the properbuckle until you hear a snap and feel itlatch. Make sure the tongue is securelyfastened in the buckle.
•Keep the buckle release buttonpointing up and away from the safetyrestraint, with the tongue between thechild restraint and the release button,to prevent accidental unbuckling.
•Place the vehicle seat upon which thechild restraint will be installed in theupright position.
•Put the seatbelt in the automaticlocking mode. See Step 5. This vehicledoes not require the use of a lockingclip.
Perform the following steps wheninstalling the child restraint withcombination lap and shoulder belts:
Note:Although the child restraintillustrated is a forward facing child restraint,the steps are the same for installing a rearfacing child restraint.
1.Position the child safety restraint in aseat with a combination lap andshoulder belt.

2.Pull down on the shoulder belt andthen grasp the shoulder belt and lapbelt together.
3.While holding the shoulder and lap beltportions together, route the tonguethrough the child restraint accordingto the child restraint manufacturer'sinstructions. Be sure the belt webbingis not twisted.
4.Insert the belt tongue into the properbuckle (the buckle closest to thedirection the tongue is coming from)for that seating position until you heara snap and feel the latch engage. Makesure the tongue is latched securely bypulling on it.
5.To put the retractor in the automaticlocking mode, grasp the shoulderportion of the belt and pull downwarduntil all of the belt is pulled out.
Note:The automatic locking mode isavailable on the front passenger and rearseats.
6.Allow the belt to retract to removeslack. The belt will click as it retractsto indicate it is in the automatic lockingmode.
7.Try to pull the belt out of the retractorto make sure the retractor is in theautomatic locking mode (you shouldnot be able to pull more belt out). If theretractor is not locked, unbuckle thebelt and repeat Steps 5 and 6.

8.Remove remaining slack from the belt.Force the seat down with extra weight,for example, by pressing down orkneeling on the child restraint whilepulling up on the shoulder belt in orderto force slack from the belt. This isnecessary to remove the remainingslack that will exist once the extraweight of the child is added to the childrestraint. It also helps to achieve theproper snugness of the child restraintto your vehicle. Sometimes, a slightlean toward the buckle will additionallyhelp to remove remaining slack fromthe belt.
9.Attach the tether strap (if the childrestraint is equipped).
10.Before placing the child in the seat,forcibly move the seat forward andback to make sure the seat is securelyheld in place. To check this, grab theseat at the belt path and attempt tomove it side to side and forward andback. There should be no more thanapproximately 1 in (3 cm) ofmovement for proper installation.
Ford recommends checking with a NHTSACertified Child Passenger SafetyTechnician to make certain the childrestraint is properly installed. In Canada,check with your local St. John Ambulanceoffice for referral to a Certified PassengerSeat Technician.
Using Lower Anchors and Tethersfor Children (LATCH)
WARNINGS
Do not attach two child safetyrestraints to the same anchor. In acrash, one anchor may not be strongenough to hold two child safety restraintattachments and may break, causingserious injury or death.
Depending on where you secure achild restraint, and depending on thechild restraint design, you may blockaccess to certain seatbelt buckleassemblies and LATCH lower anchors,rendering those features potentiallyunusable. To avoid risk of injury, make sureoccupants only use seating positionswhere they are able to be properlyrestrained.
The LATCH system is composed of threevehicle anchor points: two lower anchorslocated where the seatback and seatcushion meet (called the seat bight) andone top tether anchor located behind thatseating position.
LATCH compatible child safety restraintshave two rigid or webbing mountedattachments that connect to the two loweranchors at the LATCH equipped seatingpositions in your vehicle. This type ofattachment method eliminates the needto use seatbelts to attach the childrestraint, however the seatbelt can still beused to attach the child restraint. Forforward-facing child restraints, the toptether strap must also be attached to theproper top tether anchor, if a top tetherstrap has been provided with your childrestraint.
202018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingChild SafetyE142534

Your vehicle has LATCH lower anchors forchild restraint installation at the seatingpositions marked with the child restraintsymbol.
The LATCH anchors are located at the rearsection of the rear seat between thecushion and seatback above the symbolsas shown. Follow the child restraintmanufacturer's instructions to properlyinstall a child restraint with LATCHattachments. Follow the instructions onattaching child safety restraints with tetherstraps.
Attach LATCH lower attachments of thechild restraint only to the anchors shown.
Use of Inboard Lower Anchors from theOutboard Seating Positions (CenterSeating Use)
WARNING
The standardized spacing for LATCHlower anchors is 11 in (280 mm)center to center. Do not use LATCHlower anchors for the center seatingposition unless the child restraintmanufacturer's instructions permit andspecify using anchors spaced at least asfar apart as those in this vehicle.
The lower anchors at the center of thesecond row rear seat are spaced 18 in(46 cm) apart. A child restraint with rigidLATCH attachments cannot be installedat the center seating position. LATCHcompatible child restraints (withattachments on belt webbing) can only beused at this seating position provided thatthe child restraint manufacturer'sinstructions permit use with the anchorspacing stated. Do not attach a childrestraint to any lower anchor if an adjacentchild restraint is attached to that anchor.
Each time you use the safety restraint,check that the seat is properly attached tothe lower anchors and tether anchor, ifapplicable. Tug the child restraint from sideto side and forward and back where it issecured to your vehicle. The seat shouldmove less than approximately 1 in (3 cm)when you do this for a proper installation.
If the safety restraint is not anchoredproperly, the risk of a child being injured ina crash greatly increases.
