Possible cause/consequence
The on-board voltage is too low (the start-
er battery is discharged or nearly dis-
charged).
The engine electronics or a mechanical
component in the engine control system
is faulty.
Suggested solutions
Jump-starting may be performed.
If the engine does not start despite jump-
starting:
Consult a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Do not use too much throttle.
Have the cause rectified immediately at
a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
Non-combusted fuel can otherwise get
into the catalytic converter and damage
it.
Open the main fuse box ( page 386).
Pull out the two fuses marked
using the fuse extractor.
AUS
The engine stops.
If you wish to restart the engine:
Put the fuses back in.
