tight

the child restraint system could become
loose, incorrectly positioned or damaged
As a result, the child restraint system may not
be able to provide the intended level of pro-
tection. This poses an increased risk of injury
or even fatal injury.
Never adjust the seat after installing the child
restraint system.

passenger seat
General notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
the child restraint system on a rear seat.
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
always observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (
Y page 53).
