In order to attain the correct seating position
for children weighing over 41 lb (18 kg), it may
be necessary to use a booster seat until they
reach a height where a normal lap/shoulder
seat belt lies properly across their bodies
without the need for a booster seat.
Install the child restraint system according to
the manufacturer's instructions.
The child restraint system must be installed
firmly on both brackets.
An incorrectly installed child restraint system
can come loose in the event of an accident,
causing the child to be severely or fatally
injured.
Child restraint systems/child restraint
retaining brackets that are damaged or have
suffered damage due to an impact must be
replaced.
LATCH-type (ISOFIX) is a standardized
securing system for specially designed child
restraint systems on the rear seats.
Securing rings for two LATCH-type (ISOFIX)
child restraint systems are installed on the
left and right:
R on the rear seat backrests of the outer
seats in the second row
R on the backrests of the seats in the third
row of seats
Secure non LATCH-type (ISOFIX) child
restraint systems using the vehicle's seat belt
system. Always install child restraint systems
according to the manufacturer's instructions.
! When installing the child restraint system,
make sure that the seat belt for the center
seat does not get trapped. Otherwise, the
seat belt could be damaged.XRemove covers :.;Securing ringsXInstall the LATCH-type (ISOFIX) child
restraint system. Comply with the
manufacturer's instructions when doing
so.
Top Tether
GWARNING
Always lock the rear seat backrests in their
upright position when the rear seats are
occupied by passengers. Lock the rear seat
backrests in their upright position before
installing the Top Tether straps or when the
cargo compartment is not in use. Make sure
that rear seat backrests are secured properly
by pushing and pulling on the seat backrests.
If the seat backrest is not locked properly, the
seat backrest could fold forward. The child
restraint system is no longer supported
properly or held in position and can no longer
fulfill its function. This could cause serious or
even fatal injuries.
64Children in the vehicleSafety

GWARNING
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation.
Do not drive the vehicle without the seat head
restraints. Head restraints are intended to
help reduce injuries during an accident.
! 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
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
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
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating
materials, e.g. blankets, coats, bags,
seat covers, child seats or booster seats.
! When you move the seats, make sure that
there are no objects in the footwell or
behind the seats. Otherwise, you could
damage the seats and the objects.
! When the rear bench seat is folded
forwards, the front seats cannot be moved
to their rearmost position. You could
otherwise damage the seats and the rear
bench seat.
! Make sure that the sun visor is folded up
before adjusting the backrest and head
restraint height. The head restraint and sun
visor could otherwise collide when the head
restraint is fully extended.

Rear seat head restraints
GWARNING
For safety reasons, always drive with the rear
head restraints in the upright position when
the rear seats are occupied.
Keep the area around head restraints clear of
articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
GWARNING
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way that it
is as close to the head as possible and the
center of the head restraint supports the back
of the head at eye level. This will reduce the
potential for injury to the head and neck in the
event of an accident or similar situation.
With a rear seat occupied, make sure to move
the respective head restraint up from the
lowest non-use position and have the
occupant adjust the head restraint properly.

Important safety notesGWARNING
Never travel in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. This could cause serious or
fatal injuries. The seat backrest and seat belt
provide the best restraint when the wearer is
in a position that is as upright as possible and
the seat belt is properly positioned on the
body.
Your seat belt must be adjusted so that you
can correctly fasten your seat belt.
Never place hands under the seat or near any
moving parts while a seat is being adjusted.
After adjusting the seat, always ensure that
the seat and the backrest are correctly
engaged. The backrest must be in an upright
position.
Test the stability of the latch by pushing and
pulling the backrest. If the seat and backrest
are not correctly latched, the seat could move
forward and the backrest could fold down.
While braking, changing direction, or in an
accident, you could slide out from under the
seat belt. The child seat would no longer be
correctly supported or correctly positioned
and would no longer carry out its intended
function. This could cause serious or fatal
injuries.
Adjusting the backrest angle (2nd row
of seats)
GWARNING
The seat belt only offers its intended
protection when the seat backrest is in a
nearly vertical position and the occupant is
sitting upright. The seat backrest and seat
belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the seat belt is properly
positioned on the body.
You should therefore adjust the seat backrest
to a position as upright as possible.
The backrest angle can be adjusted to five
positions.XPull backrest release ; in the direction of
the arrow and hold it in this position.
Backrest : folds forwards.XAdjust the backrest angle as desired.XRelease backrest release ;.XLean back firmly against the backrest to
ensure that it is engaged.
Folding the seats up/down (3rd row of
seats)
The 3rd row of seats consists of two
electrically foldable individual seats, which
can be lowered into the cargo compartment.
If the seat is not correctly locked in position,
the display message: 3rd row of seats,
right-hand side not locked appears in
the multifunction display.
! Make sure that there is nothing on the
folded-down seats in the cargo
compartment. The cargo compartment
must be empty for the third row of seats to
be folded up. The seats or the objects in the
cargo compartment could otherwise be
damaged.
Make sure that the seats in the third row
are empty and not blocked before folding
them down.
