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.

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
