Seating Children Safely
To install an ISOFIX/i-Size child restraint system,
carefully read and follow the instructions provided by
the manufacturer of the child restraint system. These
instructions describe how to slide the child restraint
system onto the seat's anchor bars until you hear it
"click" into place. You may need to push the child
restraint system firmly against the seat back to ensure it
fits snugly.

Before seating a child, ensure that the child restraint
system is securely installed. Grasp the front of the child
restraint system with one hand on each side, and
attempt to:
• Twist the child restraint system from side to side.
• Pull the child restraint system away from the seat.
If the child restraint system rotates or moves away from
the seat, both latches are not fully engaged onto the
seat's anchor bars. You must reinstall it and try again. It
is critical that both latches on the child restraint system
are fully engaged.
WARNING: Do not use ISOFIX/i-Size anchors with
child restraint system or booster seats that have an
integral safety belt where the combined weight of
the child plus the child restraint system exceeds 33
kg.
Safety Leg
First and second row passenger seats in Model X
support the use of a child restraint system with a safety
leg. If the child restraint system is equipped with a leg,
extend the leg as described in the instructions provided
by the manufacturer of the child restraint system.
