74 Cockpit
Emission control system*
This warning lamp monitors the exhaust system.
Control lamp flashes:
When there is misfiring that can damage the catalytic converter. Reduce
speed and drive carefully to the nearest specialised workshop to have the
engine checked.
Control lamp is lit:
If a fault has developed during driving which has reduced the quality of the
exhaust gas (e.g. lambda probe fault). Reduce speed and drive carefully to
the nearest specialised workshop to have the engine checked.
Coolant level* / temperature
The warning lamp lights up if the coolant temperature is too
high or if the coolant level is too low.
There is a fault if:
● The warning symbol does not go out again after a few seconds.
● The warning lamp lights up or flashes while the vehicle is moving, and
three acoustic warning signals ⇒
are emitted.
This means that either the coolant level is too low or the coolant tempera-
ture is too high.
Coolant temperature too high
If the warning light comes on, stop the vehicle, switch off the engine and
wait for it to cool down. Check the coolant level.
If the coolant level is correct, the overheating may be caused by a malfunc-
tion of the radiator fan. Check the radiator fan fuse and have it replaced if
necessary ⇒ page 224.
If the control lamp lights up again after driving on for a short distance, stop
the vehicle and switch the engine off. Contact a Technical Service or a spe-
cialised workshop.
Coolant level too low
If the warning light comes on, stop the vehicle, switch off the engine and
wait for it to cool down First check the coolant level. If the level of the cool-
ant is below the “MIN” mark, top up with coolant liquid ⇒
.
WARNING
● If your vehicle is immobilised for technical reasons, move it to a safe
distance from traffic. Turn the engine off, turn the hazard lights on and
place the warning triangle.
● Never open the bonnet if you can see or hear steam or coolant escap-
ing from the engine compartment. Risk of scalding. Wait until you can no
longer see or hear escaping steam or coolant.
● The engine compartment is a dangerous area! Before carrying out any
work in the engine compartment, switch off the engine and allow it to
cool down. Always note the corresponding warnings ⇒ page 193.
Alternator
This warning lamp signals a fault in the alternator.
The warning lamp lights up when the ignition is switched on. It should
go out when the engine has started running.
If the warning lamp lights up while driving, the alternator is no longer
charging the battery. You should immediately drive to the nearest special-
ised workshop.
You should avoid using electrical equipment that is not absolutely necessa-
ry because this will drain the battery.
