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 68 for notes on airbags, see page 67 for belt
tensioners and page 57 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 2.6 gal (10 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
also page 244.
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.SRS
