Important safety notes

Basic information

Be diligent

Bear in mind that negligence when securing a

child in the child restraint system may have seri-

ous consequences. Always be diligent in securing

a child carefully before every journey.

Never allow babies and children to travel sitting

on the lap of another vehicle occupant.

To improve protection for children younger than

12 years old or under 5  (1.50 m) in height,

Mercedes-Benz recommends you observe the fol-

lowing information:

Always secure the child in a child restraint sys-

tem suitable for this Mercedes-Benz vehicle.

The child restraint system must be appropriate

to the age, weight and size of the child.

The vehicle seat must be suitable for the child

restraint system to be installed:

Accident statistics show that children secured on

the rear seats are generally safer than children

secured on the front seats. For this reason,

Mercedes-Benz strongly advises that you install a

child restraint system on a rear seat.

The generic term child restraint system

The generic term child restraint system is used in

this Operator's Manual. A child restraint system

is, for example:

a baby car seat

a rearward-facing child seat

a forward-facing child seat

a child booster seat – Mercedes-Benz recom-

mends using a child booster seat

with a back-

rest and seat belt guide.

Observe laws and legal requirements

Always observe the legal requirements when

using a child restraint system in the vehicle.

Securing systems for child restraint systems in

the vehicle

Use only the following securing systems for child

restraint systems:

the ISOFIX mounting brackets

the vehicle's seat belt system

the Top Tether anchorages

Simply attaching to the ISOFIX mounting brackets

on the vehicle can reduce the risk of installing the

child restraint system incorrectly.

When securing a child with the integrated seat

belt of the ISOFIX child restraint system, always

comply with the permissible gross weight for the

child and child restraint system (/ page 59).

A child booster seat may be necessary to achieve

proper seat belt positioning for children over

40 lbs (18 kg) in weight or until they reach a

height where a three-point seat belt can be instal-

led properly without a child booster seat.

Mercedes-Benz recommends a suitable child

booster seat with a backrest and seat belt guide.

Observe standards for child restraint systems

All child restraint systems must meet the following

standards:

U.S. Federal Motor Vehicle Safety Standards

213

Canadian Motor Vehicle Safety Standards 213

Safely transporting children in the vehicle

Conrmation that the child restraint system com-

plies with the standards can be found on an

instruction label on the child restraint system.

This conrmation can also be found in the instal-

lation instructions that are included with the child

restraint system.

bag shuto (/ page 39)

Suitable child restraint systems for the transport

of children

Information on the advantage of a rearward-facing

child restraint system

Transport a baby in a suitable rearward-facing

child restraint system only. It is also preferable to

transport a small child in a suitable rearward-

facing child restraint system. In this case, the

child sits in the opposite direction to the direction

of travel and faces backwards.

Babies and small children have comparatively

weak neck muscles in relation to the size and

weight of their head. The risk of injury to the cer-

vical spine during an accident can be reduced in a

rearward-facing child restraint system.

Securing the child restraint system

Adjusting the seat correctly

When installing a child restraint system on the le

or right rear seat, always observe the following:

Make sure that the child's feet do not touch

the front seat. If necessary, move the front

seat slightly forwards.

If the head restraint of the child restraint system

cannot be fully extended when it is installed in the

vehicle, this will result in restrictions on the maxi-

mum size setting for certain child restraint sys-

tems. Observe the child restraint system manu-

facturer's installation instructions.

Contact with the roof when the head restraint

is fully extended and locked in place will not

result in any restrictions on use.
