come on at all or if it fails to extinguish after
approximately 4 seconds or if it comes on thereafter, a
malfunction in the system has been detected.
The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.
Initially, when the electronic key is turned from starter
switch position 0 to position 1 or 2, malfunctions in the
crash sensor are detected and indicated (the “SRS”
indicator lamp stays on longer than 4 seconds or does
not come on).
Have the system checked at your authorized
Mercedes-Benz Center immediately.
In the operational mode, after the indicator lamp has
gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and front passenger seat belt buckle harnesses,
and low voltage in the entire system are detected and
indicated.Note:
See page 305 for information on the Supplemental
Restraint System (SRS) indicator lamp.
The driver and passenger front airbags are designed to
activate only in certain frontal impacts exceeding a
preset threshold. The front passenger airbag deploys
only if the front passenger seat is occupied and the
7 indicator lamp on the center console is not
illuminated.
Note:
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy in a crash exceeding the appropriate threshold.
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have the
system checked; otherwise the “SRS” may not be
activated when needed in an accident, which could
result in serious or fatal injury, or it might deploy
unexpectedly and unnecessarily which could also
result in injury.

Storing inside rear view mirror positions
The inside rear view mirror positions are stored in
memory with the seat / steering wheel / exterior rear
view mirror positions and can be recalled when
necessary. See page 108 for notes on the memory
function.
Inside rear view mirror, automatic antiglare
Antiglare mode:
With the electronic key in starter switch position 2, the
mirror reflection brightness responds to changes in
light sensitivity.
With the gear selection lever in position “R”, or with the
interior light switched on, the mirror brightness does
not respond to changes in light sensitivity.Note:
The automatic antiglare function does not react, if
incoming light is not aimed directly at sensors in the
inside rear view mirror.
The automatic antiglare function will not react for
example, if the rear window sun shade is in the raised
position.
Wa r n i n g !
In the case of an accident liquid electrolyte may
escape the mirror housing when the mirror glass
breaks.Electrolyte has an irritating effect. Do not allow the
liquid to come into contact with eyes, skin,
clothing, or respiratory system. In cases it does,
immediately flush affected area with water, and
seek medical help if necessary.
