Make sure there is nothing between the seat cushion and the
child seat.
X
Make sure that the entire base of the child restraint system rests
on the seat cushion of the front-passenger seat. The backrest of
the forward-facing child restraint system must lie as flat as possi-
ble against the backrest of the front passenger seat. If necessary,
adjust the position of the front-passenger seat.

When installing the child restraint system, make sure that the
seat belt is tight. Do not pull the seat belt tight using the front-
passenger seat adjustment. This could result in the seat belt and
the child restraint system being pulled too tightly.

Check for correct installation of the child restraint system.
Make sure that the head restraint does not apply a load to the
child restraint system. If necessary, adjust the head restraint
accordingly.

Make sure that no objects are applying additional weight onto the
seat.

If the PASSENGER AIR BAG OFF indicator lamp remains off
and/or the PASSENGER AIR BAG ON indicator lamp lights up, do
not install a child restraint system on the front-passenger seat.

Roll bar

DANGER
If the roll bar has developed a malfunction, it
may not function, e.g. in the event of an
accident. The roll bars may then not protect
the vehicle occupants as intended. This
poses an increased risk of injury or even
fatal injury.
Have roll bars checked immediately at a
qualified specialist workshop.
G
WARNING
If you place objects or clothing on the roll
bar covers, these could impair roll bar exten-
sion. The roll bars may then not protect the
vehicle occupants as intended. In addition,
objects could endanger the vehicle occu-
pants when the roll bar is extending. This
poses an increased risk of injury or even
fatal injury.
Ensure that the movement area of the roll
bar covers is kept clear. Always stow all
objects in the vehicle correctly.
