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 69 for notes on airbags, see page 68 for belt 
tensioners and page 59 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 t he “CHECK ENGINE” lamp to illuminate, see 
page 234.
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
