ProblemPossible causes/consequences and M Solutions?
The red coolant
warning lamp lights up
while the engine is
running and the coolant
temperature gauge is
at the start of the scale.The temperature sensor for the coolant temperature gauge is
faulty.
The coolant temperature is no longer being monitored. There is a
risk of engine damage if the coolant temperature is too high.XPull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions. Do not continue
driving under any circumstances.XEngage the parking brake.XConsult a qualified specialist workshop.?
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.XPull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.XAllow the engine and coolant to cool.XCheck the coolant level and add the coolant ( Y page 311).
Observe the warning notes.XIf the coolant needs adding more often than usual, have the
engine coolant system checked.XMake sure that the air supply to the radiator is not blocked, e.g.
by snow, slush or ice.XAt coolant temperatures below 248  ‡ (120  †), continue driving
to the next qualified specialist workshop.XAvoid subjecting the engine to heavy loads, e.g. driving in
mountainous terrain, and stop-start driving.?
The red coolant
warning lamp comes on
while the engine is
running. A warning tone
also sounds.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.XPull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.XAllow the engine and coolant to cool.GWarning
Driving when your engine is overheated can cause some fluids which may have leaked into the
engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening the
engine hood. Stay away from the engine if you see or hear steam coming from it.
