D
The red coolant warning lamp
lights up when the engine is run-
ning.
There is insufficient coolant in the reservoir.
If this warning lamp lights up frequently,
there is a leak in the cooling system.
If the coolant level is correct, the electric ra-
diator fan may be broken.

Immediately add coolant to prevent
engine from overheating
(page 230).

Have the cooling system checked.

If the coolant temperature is below
257 °F (125 °C), you can continue
driving to the nearest authorized
Mercedes-Benz Center.

Avoid high engine loads (e.g. driving
uphill) and stop-and-go driving.
