56 Occupant safety
Make sure that the rear bench seat, the
#
rear seat and the seat backrest are
engaged before every trip.
Ensure that the rear seat backrest is engaged. To
do so, pull forcefully on the seat backrest.
& WARNING Risk of injury or death if the
permissible gross mass of the child and
child restraint system is exceeded
Too much load may be placed on the LATCH-
type (ISOFIX) child seat securing systems
and the child may not be restrained in the
event of an accident, for example.
If the child and the child restraint sys‐
#
tem together weigh more than the per‐
missible gross mass of 73 lb (33 kg),
use only a LATCH-type (ISOFIX) child
restraint system that secures the child
with the vehicle seat belt.
Also secure the child restraint system
#
with the Top Tether belt, if available.
Always comply with the information about the
mass of the child restraint system:
in the manufacturer's installation and operat‐
R
ing instructions for the child restraint system
used
on a label on the child restraint system, if
R
present
Regularly check that the permissible gross mass
of the child and child restraint system is still
complied with.
When installing a child restraint system, observe
the following:
O Always observe the correct use of the seats
and consider their suitability for attaching a
child restraint system.
O Always comply with the manufacturer's
installation and operating instructions for
the child restraint system used.
O Make sure that the child's feet do not touch
the front seat. If necessary, move the front
seat slightly forwards.
® When installing a LATCH-type (ISOFIX)
child restraint system, also observe the follow‐
ing:
O When using a Group 0/0+ baby car seat
and a Group I rearward-facing child
restraint system on a rear seat: adjust
the front seat so that the seat does not
touch the child restraint system.
O When using a Group I forward-facing
child restraint system: remove the head
restraint from the respective seat, if possi‐
ble. In addition, the backrest of the child
restraint system must lie as flat as possible
against the backrest of the vehicle seat.
After the child restraint system has been
removed, replace the head restraint immedi‐
ately and adjust all head restraints cor‐
rectly.
O When using a child restraint system on
a seat on the third row of seats: adjust
the front seat so that it does not touch the
child restraint system and move the seat
backrest of the front seat into an upright
position if necessary.
