start. The HOLD function or DISTRONIC PLUS is activated.
X Deactivat ethe HOLD function (Y page 192) or DISTRONIC PLUS
(Y page 184).
X Try to start the engine again (Y page 147).The engine does not
start. The starter motor
can be heard. R
There is amalfunction in the engine electronics.
R There is amalfunction in the fuel supply.
Before attempting to start the engine again:
X Turn the key back to position 0in the ignition lock.
or X Press the Start/Stop button repeatedly until all indicator lamps in
the instrumen tcluster go out.
X Try to start the engine again (Y page 147). Avoid excessively long
and frequent attemptstos tart the engine, as this will drain the
battery.
If the engine does not start after several attempts:
X Consult aqualified specialist workshop. The engine does not
start. The starter motor
can be heard. The
reserve fuel warning
lamp is lit and the fuel
gauge display is at the
reserve level. The fuel tank is empty.
X Refuel the vehicle. The engine does not
start. You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak or
discharged.
X Jump-start the vehicle (Y page 345).
If the engine does not start despite attemptstoj ump-start it:
X Consult aqualified specialist workshop. The starter motor was exposed to
athermal load that was too high.
X Try to start the engine again (Y page 147).
If the engine still does not start:
X Consult aqualified specialist workshop. Vehicles with
apetrol
engine:
The engine is not running
smoothly and is misfir-
ing. There is
amalfunction in the engine electronics or in amechanical
componen tofthe engine management system.
X Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
X Have the cause rectified immediately at aqualified specialist work-

Possible causes/consequences and
M
MSolutions The coolant temperature
display is showing more
than 120 †. Adisplay
message may also
appear in the multifunc-
tion display and awarn-
ing tone may sound. The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 324). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolant level is correct,t
he engine radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled sufficiently.
X If the coolant temperature is below 120 †, you can continue driving
to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in moun-
tainous terrain and stop-start traffic. DYNAMIC SELECTs
