WARNING
•If you do not pay attention to the warning lights coming on and
the corresponding 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, accid ents and fire when working in the
engine compartment, e.g. inspecting and replenishing oil and other
fluids. It is also essential to observe all warnings ⇒page 210.
Note
•Arrangement of the indicator lights depends on the model and 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 posi-
tion 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 59.
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 59.
Low beam
The indicator light comes on when low beam is selected ⇒page 55.
Rear fog light
The warning light comes on when the rear fog lights are operating
⇒ page 57.
Alternator
The warning light comes on after the ignition has been switched on. It
should go out after the engine has started.
If the warning light does not go out after the engine has started, or comes
on when driving, drive to the nearest specialist garage. The vehicle battery
will be discharged in this case so switch off all non-essential electrical
components.
The following text will be displayed in the information display*:
ALTERNATOR WORKSHOP! (ALTERNATOR WORKSHOP!)
Caution
If the warning light comes on when driving and in addition the warning
light (cooling system fault) also comes on in display, you must then
stop the car immediately and switch the engine off - risk of engine
damage!
Fog lights*
The warning light comes on when the fog lights are operating
⇒ page 57.
Cornering lights*
If the warning light flashes for 1 minute while driving or after switching
on the ignition and a warning signal sounds, a fault is confirmed.
Further information ⇒page 56.

WARNING
If there is a fault in the cornering lights, the headlights are automat-
ically lowered to the emergency position. Thus the illuminated
length of the road is shortened. Drive carefully and have the car
inspected immediately by a specialist garage.
Electrohydraulic power steering
The warning light comes on for a few seconds when the ignition is
switched on.
If the warning light after switching on the ignition or when driving lights up
continuously, a fault exists in the electrohydraulic power steering.
•If the yellow warning light lights up, this indicates a partial or total
failure of the power steering and the steering forces can be greater.
Further information ⇒page 183.
WARNING
Contact your specialist garage if the power steering is defective.
Note
•If the yellow warning light goes out after starting the engine again
and a short drive, it is not necessary to visit a specialist garage.
•If the battery has been disconnected and reconnected, the yellow
warning light comes on after switching on the ignition. The warning light
must go out after driving a short distance.
•There is no power-assisted steering support when the vehicle is being
towed without the engine running or when the power-assisted steering is defect. The vehicle is fully steerable however. There is simply increased
force required to turn the steering wheel.
EPC fault light (petrol engine)
The (Electronic Power Control) warning light comes on for a few
seconds when the ignition is switched on.
There is a system fault in the engine control system if the warning light
does not go out or comes on or flashes while driving. The engine manage-
ment 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!
Glow plug system (diesel engine)
The indicator light lights up for a cold engine when switching on the
ignition (pre-heat position) 2 ⇒ page 110. Start the engine after the indi-
cator 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
does not
come on at all or lights up continuously. Contact a specialist garage as
soon as possible to obtain professional assistance.
There is a system fault in the engine control system if the warning light
has started to flash while driving. The engine management system selects

Turn signal system for vehicles towing a trailer*
The indicator light on vehicles towing a trailer flashes together with the
respective indicator light for the turn signal system.
The indicator light
does not flash if a turn signal light on the trailer or
on the vehicle is not operating.
Coolant temperature/coolant level
The warning light comes on for a few seconds 1) when the ignition is
switched on.
The coolant temperature is too high or the coolant level too low if the
warning light
does not go out after the engine is started 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 ⇒page 217, “Replenishing the coolant”.
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 253, “Fuse assignment at
battery”.
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 fan is in proper order.
Contact a specialist garage to obtain assistance.
Please also refer to the additional instructions ⇒page 215, “Cooling
system”.
The following text will be displayed in the information display*:
STOP 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, “Switch for hazard
warning lights ”.
•Pay attention to the following instructions ⇒page 210,
“Working in the engine compartment” before checking the coolant
fluid level and opening the bonnet.
•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
automatically even if the ignition is off.
1)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 to\
o high or the
coolant level is too low.
