Brake pad wear indicator lamp
With the key in steering lock position 2, the
brake pad wear indicator lamp comes on. It
goes out when the engine is running.
If the indicator lamp lights up during braking, this
indicates that the brake pads are worn down.
Have the brake system checked at your authorized
Mercedes-Benz Center as soon as possible.
Seat belt nonusage warning lamp
With the key in steering lock position 2, the
seat belt warning lamp comes on, and a
warning sounds for a short time if the
driver’s seat belt is not fastened.
After starting the engine, the seat belt warning lamp
blinks for a brief period to remind the driver and
passengers to fasten seat belts.
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 key in steering lock to position 1 or 2. If no
fault 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 54 for notes on airbags, see page 53 for belt
tensioners and page 44 for infant and child seat
restraint.
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.
