Mazda CX-5 2018 Owner's Manual page 54

Do not install a front-facing child-restraint
system on the front passenger seat unless it
is unavoidable:
In a collision, the force of a deploying air
bag could cause serious injury or death to
the child. If installing a front-facing
child-restraint system on the front
passenger seat is unavoidable, move the
front passenger seat as far back as possible
and adjust the seat bottom (height
adjustable seat bottom) to the highest
position at which the seat belt fastening
the child-restraint system is securely
tightened.
