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 209, “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.
Further information about the turn signal system ⇒page 60.
Fog lights
The warning light comes on when the fog lights are operating ⇒page 57.
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 60.
Low beam
The warning light comes on when low beam is selected ⇒page 53.
Rear fog light
The warning light comes on when the rear fog lights are operating ⇒ page 58.
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.
Adaptive headlights*
If the warning light flashes for 1 minute while driving or after switching on the
ignition and a warning signal sounds, a fault of the adaptive headlights is
confirmed.
Further information ⇒page 56.
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.

The warning light comes on for a few seconds 3) when the ignition is switched
on.
Stop the vehicle and sw itch the engine off if the warning light does not go off
after the engine has started or flashes while driving. Check the oil level and top up
with oil as necessary ⇒page 212.
An audible signal sounds three times as an additional warning signal.
Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Keep the engine switched off and obtain
professional assistance from a specialist garage, otherwise it could lead to severe
engine damage.
Do not drive any further if the warning light flashes even if the oil is at the correct
level. Do not run the engine not at idling speed either. Contact the nearest specialist
garage to obtain professional assistance. The following text will be displayed in the information display*:
Oil Pressure Engine off! Owner's manual
WARNING
•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
warning light system.
•The red oil pressure light is not an oil level indicator! One should
therefore check the oil level at regular intervals, preferably after every refu-
eling stop.
EPC fault light (petrol engine)
The (Electronic Power Control) warning light comes on for a few seconds when
the ignition is switched on.
If the warning light
does not go out or lights up after starting the engine, a fault
exists in the engine control. The engine management system selects an emergency

If the
warning light
begins to flash while driving, a fault exists in the engine
control. The engine management system selects an emergency programme which
enables you to drive to the nearest specialist garage by adopting a gentle style of
driving.
The following text will be displayed in the information display*:
Engine fault Workshop!
Coolant temperature/ Coolant quantity
The warning light comes on for a few seconds 4) w h e n th e i g ni t i o n i s s w i t c h e d o n .
The coolant temperature is too high or the coolant level too low if the warning light
does not go out or flashes while driving.
3 peeps sound as an additional warning signal.
In this case stop and switch the engine off and check the coolant level; top up the
coolant as necessary.
Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with coolant. Keep the engine switched off and
obtain professional assistance from a specialist garage, otherwise it could lead to
severe engine damage.
If the coolant is within the specified range, the increased temperature may be
caused by an operating problem at the coolant fan. Check the fuse for the coolant
fan, replace it if necessary ⇒page 242, “Fuse assignment in engine compartment -
version 1” or ⇒ page 244, “Fuse assignment in en gine compartment - version 2”.
Do not continue driving if the warning light does not go off although the fluid is at
the correct level and also the fuse of the fa n is in proper order. Contact a specialist
garage to obtain assistance.
Please also refer to the additional instructions ⇒page 213, “Cooling system”. The following text will be displayed in the information display*:
Check coolant! Owner's manual
WARNING
•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
warning light system ⇒ page 59.
•Take care when opening the coolant expansion bottle. If the engine is hot,
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.
Traction control system (TCS)
The warning light comes on for a few seconds when the ignition is switched on.
The warning light comes on when driving when a control cycle is activated.
The warning light will come on and remains on if the TCS is switched off or if there
is a fault in the system.
The fact that the TCS system operates together with the ABS means that the TCS
warning light will also come on if the ABS system is not operating properly.
If the warning light
comes on immediately after starting the engine, the TCS
system can be switched off for technical reasons. In this case, the TCS system can
be switched on again by swit ching the ignition on and off. If the warning light goes
out, the TCS system is fully functional again.
Further information about the TCS ⇒page 181, “Traction control system (TCS)”.
Note
If the battery has been disconnected and reconnected, the warning light comes
on after switching on the ignition. The warn ing light must go out after driving a short
distance.4)The warning light on vehicles fitted with information display does not come on after
switching the ignition on, but only if the coolant temperature is too high or the coolant level
is too low.
