WARNING
•If you do not pay attention to the warning lights coming on and the corre-
sponding descriptions and warning notes, this may result in severe body
injuries or major vehicle damage.
•The engine compartment of your car is a hazardous area. There is a risk
of injuries, scalding, accidents and fire when working in the engine
compartment, e.g. inspecting and replenis hing oil and other fluids. It is also
essential to observe all warnings ⇒page 225, “Working in the engine
compartment”.
Note
•The arrangement of the indicator light is dependent on the model version. The
symbols shown in the following functional description are to be found as indicator
lights in the instrument cluster.
•Operational faults are shown in the instrument cluster as red symbols (priority
1 - danger) or yellow symbols (priority 2 - warning).
Turn signal system
Either the left or right indicator light flashes depending on the position of the
turn signal lever.
The indicator light flashes at twice its normal rate if a turn signal light fails. This does
not apply when towing a trailer.
Switching off the hazard warning light system is switched on will cause all of the
turn signal lights as well as both indicator lights to flash.

Fog lights
The warning light comes on when the fog lights are operating ⇒page 62.
Main beam
The indicator light comes on when the main beam is selected or also when the
headlight flasher is operated.
Further information about the main beam ⇒page 65.
Low beam
The warning light comes on when low beam is selected ⇒page 59.
Rear fog light

Cruise control system*
The warning light lights up, when operating the speed regulating system.
Failure of the light bulbs
The warning light comes on if a light bulb is damaged:
•up to 2 seconds after the ignition is switched on;
•when switching on the defective light bulb. The following text e.g will be displayed in the information display*:
Check front right dipped beam!
The rear side lights and the licence plate lighting require several light bulbs. The
indicator light
only lights up if all light bulbs of the licence plate lighting or the
parking light (in one rear light unit) are defe ctive. Check regularly the function of the
light bulbs.
Diesel particle filter* (diesel engine)
If the warning light comes on, this means that soot has accumulated in the
diesel particle filter because of the frequent short distances.
In order to clean the diesel particle filter, the vehicle should be driven at an even
speed of at least 60 km/h at engine speeds of 1 800 - 2 500 rpm for at least 15
minutes or until the warning light goes ou t with the 4th or 5th gear engaged (auto-
matic gearbox: position S) when the traffi c situation permits it. This increases the
exhaust temperature and the soot deposited in the diesel particle filter is burnt.
Always pay attention to the valid speed limits ⇒.
The warning light
goes out after the successful cleaning of the diesel particle
filter.
If the filter is not properly cleaned, the warning light
does not go out and the
warning light begins to flash. In the information display* appears Diesel-
particle Owner's manual . Afterwards the engine contro l unit shifts the engine into
the emergency mode, which only has a re duced power output. After switching the
ignition off and on again the warning light
comes on.
Have the vehicle inspected without delay by your specialist garage.
WARNING
•If you do not pay attention to the warning light coming on and the corre-
sponding descriptions and warning notes, this may result in injuries or
major vehicle damage.
