Possible causes/consequences and M Solutions The coolant level is too low. If the coolant level is correct, the airflow to the radiator may be blocked or the electric radiator fan may be malfunctioning. The coolant is too hot and the engine is no longer being cooled sufficiently. X Pull over and stop the vehicle safely and switch off the engine, paying attention to road and traffic conditions. X Allow the engine and coolant to cool. X Check the coolant level and add the coolant (Y page 240). Observe the warning notes. X If the coolant needs adding more often than usual, have the engine coolant system checked. X Make sure that the air supply to the radiator is not blocked, e.g. by snow, slush or ice. X At coolant temperatures below 248 ‡ (120 †), continue driving to the next qualified specialist workshop. X Avoid subjecting the engine to heavy loads, e.g. driving in mountainous terrain, and stop-start driving. The coolant has exceeded a temperature of 248 ‡ (120 †). The airflow to the radiator may be blocked or the coolant level may be too low. The engine is not being cooled sufficiently and may be damaged. X Pull over and stop the vehicle safely and switch off the engine, paying attention to road and traffic conditions. X Allow the engine and coolant to cool. 211 ? The red coolant warning lamp comes on while the engine is running. A warning tone also sounds.

Problem

Possible causes/consequences and

Solutions

The red coolant

warning lamp comes on

while the engine is

running.

The coolant level is too low.

If the coolant level is correct, the airflow to the radiator may be

blocked or the electric radiator fan may be malfunctioning.

The coolant is too hot and the engine is no longer being cooled

sufficiently.

Pull over and stop the vehicle safely and switch off the engine,

paying attention to road and traffic conditions.

Allow the engine and coolant to cool.

Check the coolant level and add the coolant (

page 240).

Observe the warning notes.

If the coolant needs adding more often than usual, have the

engine coolant system checked.

Make sure that the air supply to the radiator is not blocked, e.g.

by snow, slush or ice.

At coolant temperatures below 248 ‡ (120 †), continue driving

to the next qualified specialist workshop.

Avoid subjecting the engine to heavy loads, e.g. driving in

mountainous terrain, and stop-start driving.

The red coolant

The coolant has exceeded a temperature of 248 ‡ (120 †). The

airflow to the radiator may be blocked or the coolant level may be

too low.

The engine is not being cooled sufficiently and may be damaged.
