Booster Cushion (Group 3)
ISOFIX Anchor Points
WARNING
Use an anti-rotation device when
using the ISOFIX system. We
recommend the use of a top tether
or support leg.
Your vehicle has ISOFIX anchor points that
accommodate universally approved
ISOFIX child seats.
Child Safety
The ISOFIX system has two rigid
attachment arms on the child seat that
attach to anchor points on the second row
seats, where the cushion and backrest
meet. Tether anchor points are fitted to
the underside or rear of the second row
seats for child seats with a top tether.
Note: When you are purchasing an ISOFIX
seat, make sure that you know the correct
mass group and ISOFIX size class for the
intended seating locations. See Child Seat
Positioning (page 17).
