•
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 lights depends 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 symb
ols (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 ra
te 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.
Further information about
the turn signal system
⇒page 64.
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 64.
Low beam
The warning light
comes on when low beam is selected
⇒page 58.
Rear fog light
The warning light
comes on when the rear fog lights are operating

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 control unit shifts the engine into
the emergency mode, which only has a reduced 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.•
Always adjust your speed to suit weather, road, region and traffic condi-
tions. The route indicated by the warning light must not tempt you to disre- gard the national regulations for road traffic.
Caution
As long as the warning light
lights up, one must take into account an increased
fuel consumption and in certain circumst
ances a power reduction of the engine.
