Top Tether
Introduction Top Tether provides an additional connection
between the child restraint system secured with
a LATCH-type (ISOFIX) system and the vehicle.
This helps reduce the risk of injury even further.
If the child restraint system is equipped with a
Top Tether belt, this should always be used.
Important safety notes
G WARNING
If the rear seats or the rear seat backrests are
not locked, they could fold forwards in the
event of an accident, heavy braking or sudden
changes of direction. As a result, child
restraint systems cannot perform their inten-
ded protective function. Rear seats and rear
seat backrests that are not locked can also
cause additional injuries, e.g. in the event of
an accident. This poses an increased risk of
injury or even fatal injury.
Always lock the rear seats and rear seat
backrests after installing a Top Tether belt.
Observe the lock verification indicator. Adjust
the rear seat backrests so that they are in an
upright position.
Make sure that the backrest in the rear com-
partment engages fully. To do so, pull firmly on
the seat backrest.
Top Tether anchorages
The Top Tether anchorages for the second row
of seats are located on the rear of the rear seat
backrests. For the third row of seats, use the cargo tie-down rings in the cargo compartment
floor.
X
Move head restraint

G WARNING
You could lose control of your vehicle if you do
the following while driving: R
adjust the driver's seat, head restraint,
steering wheel or mirrors R
fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt
before starting the engine.
G WARNING
If you adjust the seat height carelessly, you or
other vehicle occupants could be trapped and
thereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem.
G WARNING
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the
event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
G WARNING
The seat belt does not offer the intended level
of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury. Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
! To avoid damage to the seats and the seat
heating, observe the following information: R
keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible. R
if the seat covers are damp or wet, do not
switch on the seat heating. The seat heat-
ing should also not be used to dry the seats. R
clean the seat covers as recommended;
see "Interior care". R
do not transport heavy loads on the seats.
Do not place sharp objects on the seat
cushions, e.g. knives, nails or tools. The
seats should only be occupied by passen-
gers, if possible. R
when the seat heating is in operation, do
not cover the seats with insulating materi-
als, e.g. blankets, coats, bags, seat covers,
child seats or booster seats.
! Make sure that there are no objects in the
footwell under or behind the seats when mov-
ing the seats back. There is a risk that the
seats and/or the objects could be damaged.
i It is not possible to remove the head
restraints from the front seats. The rear-com-
partment head restraints, however, can be
removed ( Y
page 98).
For more information, contact a qualified spe-
cialist workshop.
