ans that either the coolant level is too
low or the coolant temperature is too high.
Coolant temperature too high
If the lamp lights up, stop the vehicle,
turn off the engine and wait for it to cool
down. Check the coolant level.
If the coolant level is correct, the overheating
may be caused by a malfunction of the radia-
tor fan. Check the radiator fan fuse and have
it replaced if necessary ››› page 104.
If the control lamp lights up again after driv-
ing on for a short distance, stop the vehicle
and switch the engine off. Contact a Techni-
cal Service or a specialised workshop.
Coolant level too low
If the lamp lights up, stop the vehicle,
turn off the engine and wait for it to cool
down. First check the coolant level. If the lev-
el of the coolant is below the “MIN” mark,
top up with coolant liquid ›››
