Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child and recommended for
use by Mercedes-Benz.
Ensure that the infant or child is prop-
erly secured by a belt at all times while
the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Center.
Infant and child restraint systems
Use only a BabySmart
TM compatible child
restraint for the front passenger seat in
this vehicle.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During seat belt retraction, a ratch-
eting sound can be heard to indicate that
the special seat belt retractor is activated.
The belt is now locked. Push down on child
restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual man-
ner.
