Users Manual Part 1

R
The child restraint system must be appropri‐
ate to the age, weight and size of the child.
R
The vehicle seat must be suitable for fitting a
child restraint system (/ page 57).
Accident statistics show that children secured
on the rear seats are generally safer than chil‐
dren secured on the front seats. For this reason,
Mercedes-Benz strongly advises that you fit a
child restraint system to a rear seat.
Generic term "child restraint system"
The generic term child restraint system is used
in this Owner's Manual. A child restraint system
is, for example:
R
a baby car seat
R
a rearward-facing child seat
R
a forward-facing child seat
R
a child booster seat with a backrest and seat
belt guide
Mercedes-Benz recommends using a child
booster seat with a backrest.
The child restraint system must be appropriate
to the age, weight and size of the child.
Observing laws and legal requirements
Always observe the legal requirements when
using a child restraint system in the vehicle.
Make sure that the child restraint system is
approved in accordance with the valid test speci‐
fications and guidelines. Further information can
be obtained at a qualified specialist workshop.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this purpose.
Only use approved child restraint systems
Only child restraint systems that meet the fol‐
lowing UNECE standards are permitted for use in
the vehicle:
R
UN-R44
R
UN-R129 (i-Size child restraint systems)
Information on child restraint system approval
categories and details on the approval label on
the child restraint system (/ page 57).
Detecting risks, avoiding danger
Securing systems for child restraint systems
in the vehicle
Only use the following securing systems for child
restraint systems:
R
the ISOFIX or i-Size mounting brackets
R
the vehicle's seat belt system
R
the Top Tether anchorages
Fitting an ISOFIX or an i-Size child restraint sys‐
tem is preferred.
Simply attaching to the securing rings on the
vehicle can reduce the risk of fitting the child
restraint system incorrectly.
When securing a child with the integrated seat
belt of the ISOFIX or i-Size child restraint sys‐
tem, always comply with the permissible gross
weight for the child and child restraint system
(/ page 60).
Advantage of a rearward-facing child
restraint system
It is preferable to transport a baby or a small
child in a suitable rearward-facing child restraint
