Bear in mind that negligence when securing the

To impr oveprotection forch ildren younger than

Mercedes-Benz recommends you alw ays obser ve
th efo llowing no tes:
R Always secure thech ild in a child restra int
sy stem suitable foryo ur Mercedes-Benz vehi‐

R The child restra int sy stem must be appropri‐
ate tothe age, weight and size of thech ild.
R The vehicle seat must be suitable forth ech ild

Alw ays ins tall a child restra int sy stem on a suita‐
ble rear seat. Accident statistics show that chil‐
dren secured on there ar seats are safer than
ch ildren secured on the co-driver seat.
Ac cident statistics show that children secured on
th ere ar seats are general lysafer than children
secured on the front seats. Forth is reason,
Mercedes-Benz strongly advises that you ins tall a
ch ild restra int sy stem on a rear seat.
The generic term ch ildrestra int sy stem
The generic term child restra int sy stem is used in
th ese Operating Instructions. A child restra int
sy stem is, forex ample:
R A baby car seat
R Arear wa rd-facing child seat
R Aforw ard-facing child seat
R Ach ild boos ter seat with a backrest and seat
belt guides
The child restra int sy stem must be appropriate to
th e age, weight and size of thech ild.

Observing thest andards forch ild restra int

All child restra int sy stems must meet thefo llow‐

Only use thefo llowing securing sy stems forch ild

R The LATC H-type (ISOFIX) secu ring rings
R The seat belt sy stem of theve hicle
R The TopTe ther anchorages
Ins talling a LATC H-type (ISOFIX) child restra int
sy stem is prefer red.
Simply attaching tothe securing rings on the

When securing a child with the integrated seat
belt of theLA TC H-type (ISOFIX) child restra int
sy stem, alw ays comply with the permissible gross

A boos ter seat may be necessary toachie ve
proper seat belt positioning forch ildren over
40 lbs (18 kg) un tilthey reach a height where a
th re e-point seat belt fits properly wi thout a boos‐
te r seat.
Mercedes-Benz recommends a child boos ter seat
with a backrest and seat belt guides.
Ad vantage of a rear wa rd-facing child restra int

It is preferable totranspo rta baby or a small
ch ild in a suitable rear wa rd-facing child restra int

R Bear in mind that the handling characteristics
are more uns table when towing a trailer than
when driving without a trailer. Avoid sudden

R The vehicle/trailer combination is heavier,
accelerates more slowl y,has a reduced
