Supplemental restraint system (SRS) indicator lamp
The operational readiness of the airbag
system is verified by the indicator lamp
“SRS” in the instrument cluster when
turning the electronic key in steering lock to position 1
or 2. If no malfunction is detected, the lamp will go out
after approximately 4 seconds; after the lamp goes out,
the system continues to monitor the components and
circuitry of the airbag system and will indicate a
malfunction by coming on again.
See page 66 for notes on airbags, see page 65 for belt
tensioners and page 74 for infant and child seat
restraint.
Fuel reserve and fuel cap placement warning
When the warning lamp (1) comes on after starting the
engine, or if it comes on while driving, it indicates that
the fuel level is down to the reserve quantity of
approximately 2.1 gal (8 liters).
The warning lamp blinks when the fuel cap is not
closed, or a fuel system leak has been detected.
Retighten cap and see if lamp goes out after restart and
next OBD selfcheck.
If the warning lamp continues to blink after closing the
fuel cap correctly, have the fuel system checked at your
authorized Mercedes-Benz Center as soon as possible.
Leaving the engine running and the fuel cap open can
also cause the “CHECK ENGINE” lamp to illuminate, see
page 228.
Warning!
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.
