Child seat anchors – LATCH type
This vehicle is equipped with two LATCH
(Lower A
nchors and T
ethers for CH
ildren)
type anchors (at each of the rear seats) for
the installation of a LATCH-type child seat
with matching mounting fittings.
Depending on vehicle production date,
your vehicle is equipped with either
LATCH-type design A or B.
iYour cabriolet does not have and is not
required to have anchorage rings for a
child seat’s top tether strap in the rear
seating positions. Child seats can be
used with the seat belt, or lower anchor
system and seat belt, fully in accor-
dance with the child seat manufactur-
er’s instructions.
Warning!
G
Children too big for a toddler restraint must
ride in seats using regular seat belts.
Position shoulder belt across chest and
shoulder, not face or neck.
A booster seat may be necessary to achieve
proper belt positioning for children from
41 lbs until they reach a height where a
lap/shoulder belt fits properly without a
booster.
Install child seat according to manufactur-
er’s instructions.
The child seat must be firmly attached in the
right and left side anchor2.
An incorrectly mounted child seat may come
loose during an accident which could result
in serious injury or death to the child.
Damaged or impact damaged child seats or
child seat anchor fittings must be replaced.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system.
iThe child seat must be firmly attached
in the right and left side anchor2.iNon-LATCH type child seats may also
be used and can be installed using the
vehicle’s seat belt system (
page 69).
Install child seat according to the
manufacturer’s instructions.

Rear seat head restraints
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the center of
the head restraint supports the back of the
head at eye level. This will reduce the poten-
tial 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 intend-
ed to help reduce injuries during an
accident.
iAdjust the head restraint in such a way
that it is as close to the head as
possible.
Warning!
G
For safety reasons, always drive with the
rear head restraints in the raised position
when the rear seats are occupied.
Keep the area around head restraints clear
of articles (e.g. clothing) to not obstruct the
lowering/raising operation of the head
restraints.
