Instruments and Indicator/Warning Lights
Glow plug system

The indicator light
lights up for a cold engine when switching on the ignition
(pre-heat position) 2 ⇒ page 100. Start the engine just as soon as the indicator light
goes out.
The glow plug indicator light will come on for about 1 second if the engine is at a
normal operating temperature or if the outside temperature is above +5°C. This
means that you can start the engine right away.
There is a fault in the glow plug system if the indicator light
at all or lights up continuously. Contact a specialist garage as soon as possible to
obtain assistance.
There is a system fault in the engine control system if the warning light
started to flash while driving. The engine management system selects an emer-
gency programme which enables you to drive to the nearest specialist garage by
adopting a gentle style of driving.

If you must stop for technical reasons, then park the vehicle at a safe
distance from the traffic and switch off the engine and switch on the hazard

the cooling system is pressurized - risk of scalding! It is best to allow the
engine to cool down before removing the cap.

Do not touch the coolant fan! The coolant fan may switch on automati-
cally even if the ignition is off.
