as intended.
Never modify the seat belts, Emergency
#
Tensioning Devices, seat belt ancho‐
rages or seat belt retractors.
Make sure that the seat belts are not
#
damaged, are not worn and are clean.
Always have the seat belts checked
#
immediately after an accident at a
qualified specialist workshop.
Only use seat belts that are approved for your
vehicle by Mercedes-Benz.
& WARNING Risk of injury or death from
deployed pyrotechnic Emergency Ten‐
sioning Devices
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer opera‐
tional and are unable to perform their inten‐
ded protective function.
Therefore, have deployed pyrotechnic
#
Emergency Tensioning Devices immedi‐
ately replaced at a qualified specialist
workshop.
Mercedes-Benz recommends that you have the
vehicle towed to a qualified specialist workshop
after an accident.
* NOTE Damage caused by trapping the
seat belt
If an unused seat belt is not fully retracted, it
may become trapped in the door or in the
seat mechanism.
Always ensure that an unused seat belt
#
is fully retracted.
Information on the belt airbag in the rear
seat belt
The BELTBAG identification indicates that a rear
seat belt is equipped with a belt airbag.
When activated, the belt airbag increases the
protected area of the vehicle occupant's ribcage.
& WARNING Risk of injury or death
through the use of a non-approved child
restraint system
In an accident, the belt air bag may damage
a non-approved or non-authorized child
restraint system.
As a result, the child restraint system may
not be able to provide the intended level of
protection.
Therefore, always use LATCH or LATCH-
#
type (ISOFIX) to fasten a child seat
equipped with an integrated restraint
system.
For vehicles equipped with the optional
#
rear seat-belt air bags ("beltbag"), only
use a Mercedes-Benz approved booster
seat with integrated backrest.
Never use an air bag equipped seat belt
#
to fasten a front or rear-facing child
seat or a non-approved booster seat.
Please contact an authorized
#
Mercedes-Benz Center for information
on approved child restraint systems.
