The engine will not start. You cannot hear
the starter motor working.
The on-board voltage is too low because
the starter battery is too weak or dis-
charged.
Jump-start the vehicle ( page 497).
If the engine does not start despite at-
tempts to jump-start it:
Consult a qualified specialist workshop.
The starter motor has overheated. Allow the starter motor to cool down for
approximately two minutes.
Restart the engine.
If the engine still does not start:
Consult a qualified specialist workshop.
The engine is not running smoothly and is
misfiring.
The engine electronics or a mechanical
component of the engine control unit have
been damaged.
Only depress the accelerator pedal gen-
tly.
Have the cause rectified immediately at
a qualified specialist workshop.
Otherwise, unburnt fuel may get into the
catalytic converter and damage it.
