discharged.
X Jump-start the vehicle (Y page 227).
If the engine does not start despite attempt stojump-start it:
X Consult aqualified specialist workshop. The starter motor was exposed to excessively high thermal load.
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 aqualified specialist workshop. The coolant temperature
display is showing more
than 120 †. Adisplay
message may also
appear in the multifunc-

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 215). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolan
tlevel is correct, the radiator fan may be faulty. The cool-
ant is too hot and the engine is not being cooled sufficiently.
X If the coolant temperature is below1 20 †, you can continue driving
to the nearest qualifieds pecialist workshop.
X Avoid heavy loadsont he engine as you do so, e.g. driving in moun-

eand care

The following cause engine failure or damage
to the exhaust system:
R Use of engine oils and oil filters that have
not been expressly approved for the service
system
R Replacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
R Use of engine oil additives
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick ,too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter .Have excess oil siphoned off. H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment. X
Turn cap :anti-clockwise and remove it.
X Top up with the amount of engine oil required.
Observe the specification sinthe on-board com-
puter when doing so or fill carefully to the max- imum mark on the oil dipstick.
The differenc ebetween the minimum mark and
the maximum mark on the oil dipstick is approx- imately 2.0 litres.
X Replace cap :on the filler neck and turn
clockwise.
Make sure that the cap locks securely into
place.
