The red coolant
warning lamp
comes on while
the engine is
running. Awarn-
ing tone also
sounds. The coolant temperature has exceeded 130 †. 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.
X Make sure that the air supply to the radiator is not blocked, e.g.
by slush.
X Check the coolant level (Y page 183). Observe the warning
notes.
X If necessary, top up the coolant.
X Have the engine cooling system checked at aqualified specialist
workshop if the coolant needs topping up more often than usual.
If the coolant level is correct,t he electric radiator fan may be
faulty.
X Do not continue driving under any circumstances.
X Consult aqualified specialist workshop. 00BB

0050Solutions Vehicles with
apetrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is
amalfunction in the engine electronics or amechanical
componentoft he engine control unit.
X Only depress the accelerator pedal slightly.
X Have the cause rectified immediately at aqualified specialist
workshop.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it. The coolant tempera-
ture gauge shows a
value above 120 †.
The coolant warning
lamp may also light up
and awarning tone may
sound (Y page 107). 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 183). Observe the warning
notes as you do so and top up the coolant if necessary. If the coolant level is correct,t
he radiator fan may be faulty. The
coolant is too hot and the engine is no longer being cooled suffi-
ciently.
X If the coolant temperature is less than 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 on
mountain roads and stop/start driving. 242

The antifreeze/corrosio ninhibitor concentra-
tio nint hecoolin gsystem should:
R be at least 50%. This will protect th ecooling
system against freezing down to around
-3 7†.
R no te xcee d5 5% (antifreez eprotection
down to -4 5†)otherwise heat will no tbe
