Be diligent
Bear in mind that neglecting tosecure a child in
th ech ild restra int sy stem may ha veserious con‐
sequences. Alw ays be diligent in securing a child
carefully before everyjou rney.
To impr oveprotection forch ildren younger than
12 years old or under 5 ft(1.50 m) in height,
Mercedes-Benz recommends you obse rvethe
fo llowing information:
R Alw ays secure thech ild in a child restra int

cle. 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 for ins tal‐
ling a child restra int sy stem.
Ac cident statistics show that children secured in
th ere ar seats are generally sa ferth an children
secured in 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.

R theLA TC H-type (ISOFIX) mounting brac kets
R theve hicle's seat belt sy stem
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 weight forth ech ild and child restra int sys‐

A boos ter seat may be necessary toachie ve
proper seat belt positioning forch ildren over
40 lbs (18 kg) in weight or until they reach a
height where a thre e-point seat belt can be
ins talled proper lywithout a boos ter seat. Mercedes-Benz
recommends a suitable child
boos ter seat with a backrest and seat belt guide.
Ad vantage of a rear wa rd-facing child
re stra int sy stem
It is preferable totranspo rta baby or a small
ch ild in a suitable rear wa rd-facing child restra int
sy stem. In this case, thech ild sits in the oppo‐
site direction tothe direction of tr avel and faces
ba ckwa rds.
Babies and small children ha vecompa ratively
