type (ISOFIX) child restraint system is
engaged correctly in both LATCH-type (ISO-
FIX) securing rings
! When installing the child restraint system,
make sure that the seat belt for the middle seat does not get trapped. The seat belt
could otherwise be damaged. LATCH-type (ISOFIX) securing rings
;on the
rear seats are covered by a Velcro-fastened
upholstered lining :.

WARNING
Vehicles with electrically adjustable rear
bench seats:
If you adjust the seat after installing a child
restraint system:
R the seat belt could slacken or become too
tight
R the child restraint system could become
loose, incorrectly positioned or damaged
As a result, the child restraint system may not
be able to provide the intended level of pro-
tection. This poses an increased risk of injury or even fatal injury.
Never adjust the seat after installing the child
restraint system.
Vehicles without rear reclining seat: after
you have removed the LATCH-type (ISOFIX)
child restraint system, you must turn the sup-
port on the rear side of upholstered lining :
by 90° again. Then fold upholstery lining :
down.
ISOFIX is a standardized securing system for
specially designed child restraint systems on
the rear seats. LATCH-type (ISOFIX) securing rings ;for two LATCH-type (ISOFIX) child
restraint systems are installed on the left and
right rear seats.
Vehicles with rear seat armrest: adjust the
rear seat armrest so that LATCH-type (ISO-
FIX) securing rings ;for the LATCH-type
(ISOFIX) child restraint system are accessi-
ble.
Non-LATCH-type (ISOFIX) child seats may
also be used and can be installed using the
