WARNING Risk of injury or death due to
use of a non-approved child restraint sys‐
tem
In an accident, the belt airbag may damage a
non-approved child restraint system or a
child restraint system which has not been
approved for use in conjunction with the belt
airbag.
As a result, the child restraint system may
not be able to provide the intended level of
protection.
For safety reasons, Mercedes-Benz recom‐
mends that you only use a child restraint sys‐
tem which has been tested and approved by
Mercedes-Benz in combination with a belt
airbag.
