WARNING: If the head restraint has been removed from a
seating position to accommodate a high-back child restraint, the
head restraint must be re-installed prior to use of the seat by any other
occupant in order to reduce the risk of personal injury in the event of
a collision.
Airbags can kill or injure a child in a child seat. NEVER place a
rear-facing child seat in front of an active airbag. If you must use a
forward-facing child seat in the front seat, move the vehicle seat all the
way back.
Children 12 and under should be properly restrained in a rear seating
position whenever possible. If all children cannot be seated and
restrained properly in a rear seating position, properly restrain the
largest child in the front seat.
Installing child safety seats with combination lap and shoulder
belts
Check to make sure the child seat is properly secured before each use.
When installing a child safety seat with combination lap/shoulder belts:
• Use the correct safety belt buckle for that seating position.
• Insert the belt tongue into the proper buckle until you hear a snap
and feel it latch. Make sure the tongue is securely fastened in the
buckle.
• Keep the buckle release button pointing up and away from the safety
seat, with the tongue between the child seat and the release button,
to help prevent accidental unbuckling.
• Put the safety belt in the automatic locking mode. Refer to Step 5
below. This vehicle does not require the use of a locking clip.
WARNING: Depending on where you secure a child restraint,
and depending on the child restraint design, you may block
access to certain safety belt buckle assemblies and/or LATCH lower
anchors, rendering those features potentially unusable. To avoid risk of
injury, occupants should only use seating positions where they are able
to be properly restrained.
