Mercedes-Benz 300 E 1990 Owner's Manual page 46

The following system components
are monitored or undergo a self­
check: crash-sensor, airbag
ignition circuit, driver and front
passenger seat belt buckles.
Initially, when the key is turned
from steering lock position 0 to
positions 1 or 2, malfunctions in
the crash-sensor are detected and
indicated (the " SRS" indicator
lamp stays on longer than 4 sec­
onds).
In the operational mode, after the
indicator lamp has gone out after
the initial check, interruptions and
short circuits in the airbag ignition
circuit and in the driver and front
passenger seat belt buckle har­
nesses, and low voltage in the
entire system are detected and
indicated.

In the event a malfunction of the
" SRS" is indicated as outlined
above, the " SRS" may not be
operational. We strongly re­
commend that you visit an
authorized MERCEDES-BENZ
dealer immediately to have the
system checked; otherwise the
" SRS" may not be activated in a
major frontal accident.
Important note:
The airbag is designed to
activate only in major frontal
and front-angled impacts
(within the shaded area as
shown in the illustration on
page 42) which may cause
severe injuries. Only during
these types of impacts will it
provide its supplemental pro­
tection. The driver should al­
ways wear the seat belt, other­
wise it is not possible for the
airbag to provide its intended
protection.
In cases of less severe frontal
impacts, roll-overs, certain side
impacts, rear collisions, or other
accidents without severe frontal
forces, the airbag will not be ac­
tivated. The driver and other
passengers will then be protected
by the fastened seat belts.
