For standard front seats without rear seats,route the tether strap over the top of theseat.
If you install a child restraint and youattach the top tether strap to the propertop tether anchor, do not tighten the tetherstrap enough to lift the child restraint offthe vehicle seat cushion when the child isseated in it. Keep the tether strap just snugwithout lifting the front of the childrestraint. Keeping the child restraint justtouching the vehicle seat gives the bestprotection in a severe crash.
See the Child Safety chapter in your baseOwner's Manual for more information.

WARNING: Depending on whereyou secure a child restraint, anddepending on the child restraint design,you may block access to certain seatbeltbuckle assemblies and LATCH loweranchors, rendering those featurespotentially unusable. To avoid risk ofinjury, make sure occupants only useseating positions where they are able tobe properly restrained.
When installing a child restraint withcombination lap and shoulder belts:

3.While holding the shoulder and lap beltportions together, route the tonguethrough the child restraint accordingto the child restraint manufacturer'sinstructions. Make sure that you havenot twisted the belt webbing.
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.

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.

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 than1 in (2.5 cm) of movement for properinstallation.
We recommend checking with a NHTSACertified Child Passenger SafetyTechnician to make certain the childrestraint is properly installed. In Canada,check with Transport Canada for referralto a Child Car Seat Clinic.
Using Lower Anchors and Tethersfor CHildren (LATCH)
WARNING: Do not attach two childsafety restraints to the same anchor. Ina crash, one anchor may not be strongenough to hold two child safety restraintattachments and may break, causingserious injury or death.
WARNING: Depending on whereyou secure a child restraint, anddepending on the child restraint design,you may block access to certain seatbeltbuckle assemblies and LATCH loweranchors, rendering those featurespotentially unusable. To avoid risk ofinjury, make sure occupants only useseating positions where they are able tobe properly restrained.
WARNING: The center of the rearseat is not designed as a seating positionand is not equipped with seatbelts. TheLATCH anchors were not designed to beused with a child restraint in the centerposition and there is no tether anchoravailable at the center. Do not attemptto use the center as a seating positionas this will increase the risk of injury ordeath in the event of a crash.
The LATCH system has three vehicleanchor points: two lower anchors wherethe seat backrest and seat cushion meet(called the seat bight) and one top tetheranchor behind that seating position.
LATCH compatible child restraints havetwo 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, you can still use theseatbelt to attach the child restraint. Forforward-facing child restraints, you mustalso attach the top tether strap to theproper top tether anchor, if a top tetherstrap has been provided with your childrestraint.
