more than 120 †. The
coolant warnin glamp
may also be lit and a
warning 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 363). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct
,the radiator fa nmay be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X At coolant temperatures under 120 †, drive on to the nearest
qualified specialis tworkshop, e.g. to aMercedes-Benz Service
Centre.
X Avoid heavy loads on the engine as you do so, e.g. driving in
mountainous terrai nand stop-start traffic. Automatic transmission

X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.

! Vehicles with adiesel particle filter: if
the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur durin gthe automa ticc leaning of the
diesel particle filter. This may lead to fuel
