Problem
Possible causes/consequences and
X XSolutions The engine will not
start. You can hear the
starter motor operat-
ing. R
There is a malfunction in the engine electronics.
R There is a malfunction in the fuel supply.
R The on-board voltage is too low because the starter battery is
too weak or discharged.
X Before the next start attempt, turn the key back to position 0
(Y page 182) in the ignition lock or press the Start/Stop but-
ton* until all the indicator lights in the instrument cluster have
gone out.
X Try to start the engine again (Y page 202). When doing so,
remember that excessively long and frequent attempts to start
the engine will drain the battery.
If the engine does not start after several attempts:
X Consult a qualified specialist workshop. The engine will not
start. You cannot hear
the starter motor. The on-board voltage is too low because the starter battery is too
weak or discharged.
X
Jump-start the vehicle (Y page 384).
If the engine does not start despite attempting to jump-start it:
X Consult a qualified specialist workshop. The starter motor was exposed to a thermal load that was too high.
X
Allow the starter motor to cool down for approximately two
minutes.
X Try to start the engine again.
If the engine still does not start:
X Consult a qualified specialist workshop. The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or a mechanical
component of the engine control unit.
X
Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at a qualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. 358
