Top Tether provides an additional connection between the child restraint system secured with ISOFIX and the rear seat. It helps reduce the risk of injury even further.

The Top Tether anchorage points are located in the rear compartment behind the head restraints.

Vehicles with electrically adjustable rear seats: move the rear seat backrests to an upright position.
Remove respective covering cap 1 of the Top Tether anchorage.
Place covering cap 1 in a suitable place (e.g. in the glove box).

Move the head restraint upwards.
Route Top Tether belt 4 under the head restraint between the two head restraint bars.
Hook Top Tether hook 3 of Top Tether belt 4 into Top Tether anchorage 2.

Ensure that:
• Top Tether hook 3 is hooked into Top Tether anchorage 2 as shown.
• Top Tether belt 4 is not twisted.
• Top Tether belt 4 can move freely between the rear seat backrest and the head restraint.

Install the LATCH-type (ISOFIX) child restraint system with Top Tether. Comply with the manufacturer's installation instructions when doing so. Make sure that Top Tether belt 4 is tight.

The child restraint system with Top Tether belt 4 has been removed:
Slide covering cap 1 onto Top Tether anchorage 2.

WARNING
Vehicles with rear power seats:
Never change the rear seat position after installing the child restraint. This could
• damage the child restraint
• introduce undesirable slack or tension into the seat belt
• loosen the child restraint
• misposition the child restraint
All of the above will lessen the effectiveness of the child restraint and thus increase the chance or severity of injury in an accident.
