Self-Test BabySmart™
Without Special Child Seat
installed
The SRS uses two crash severity levels
(thresholds) to activate either the ETR
or airbag or both. Activation depends
on the direction and severity of the
impact, exceeding the thresholds and
fastening of the seat belt.
The emergency tensioning retractors are
designed to activate only when the seat
belts are fastened during frontal and
front-angled impacts exceeding the first
threshold of the SRS. They remove slack
from the belts in such a way that the seat
belts fit more snugly against the body
restricting its forward movement as
much as possible.
After turning key in steering lock to
position 1 or 2, the
indicator
lamp located on center console comes
on for approx. 6 seconds.
Seat belt fastened
If the lamp should not come on or is
continuously lit, the system is not
functioning. You must see an authorized
Mercedes-Benz dealer before using any
child seat.

In cases of other frontal impacts, roll-
overs, certain side impacts, rear
collisions, or other accidents without
frontal forces, the emergency tensioning
retractors will not be activated. The
driver and passengers will then be
protected by the fastened seat belts and
inertia reel in the usual manner.

System means that airbags are intended
as a supplement to seat belts. Airbags
alone cannot protect as well as airbags
plus seat belts in impacts for which the
airbags were designed to operate, and
do not afford any protection
Emergency Tensioning
Retractor (ETR)
The seat belts for the front seats are
equipped with emergency tensioning
retractors. These tensioning retractors
are located in each belt's inertia reel
and become operationally ready with
the key in steering lock position 1 or 2.
