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 impacts
exceeding the first threshold of the SRS
and in rear impacts exceeding a preset
security level. 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.
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, angled

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.

Supplemental Restraint System
(SRS)
Driver and front passenger systems
operate independently from each other.

retractor safety guidelines see Safety
Guidelines in Index.
The term Supplemental Restraint
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
