Modified Emergency Tensioning Devices can
accidentally trigger or fail to function 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
#
undamaged, not worn and clean.
Always have the seat belts checked
#
immediately after an accident at a
qualified specialist workshop.
Only use seat belts which have been approved
for your vehicle by Mercedes-Benz.
The AMG sport seat and the AMG Performance
seat are designed for the standard three-point
seat belt. If you install a different multipoint seat
belt, e.g. sport or racing seat belts, the restraint
system cannot provide the intended level of pro‐
tection.
Depending on the type of seat, there may be
openings in the seat backrest. These openings
have no function.
& WARNING Risk of injury or fatal injury
due to modified seat belt systems
If you feed seat belts through the opening in
the seat backrest, the seat backrest may be
damaged or may even break in the event of
an accident.
Only use the standard three-point seat
#
belt.
Never modify the seat belt system.

& 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.
Occupant safety
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.
Fastening and adjusting the seat belts
If the seat belt is pulled quickly or sharply, the
seat belt retractor locks. The seat belt strap can‐
not be pulled out any further.
