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, accidents 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 248.
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 on 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 68.
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 68.
Low beam 
The indicator light  comes on when low beam is selected ⇒page 63.
The rear fog light 
The warning light  comes on when the rear fog lights are operating
⇒ page 65.
Electronic immobiliser 
Data is compared between the ignition key and the control unit when
switching on the ignition. The indicator light  will light up for a few
seconds when ignition key authorisation is confirmed.
The warning light will start flashing continuously if a non-authorised igni-
tion key (for example the wrong ignition key) has been used. The engine
cannot be started ⇒page 45.
It is only possible to start the engine of the vehicle with a Genuine Škoda
key with the matching code.

Diesel particle filter (diesel engine)
In the diesel particle filter the resulting soot particles are
collected and burnt during the combustion of diesel fuel.
Code 7GG on the vehicle data sticker ⇒fig. 20 indicates that your
vehicle is equipped with a diesel particle filter. The vehicle data
sticker ⇒page 303, fig. 234 is located on the floor of the luggage
compartment and is also stated in the Service schedule.
The soot particles, which result from the combustion of diesel fuel, are
collected in the diesel particle filter . If the filter is full, the warning light 
lights up in the instrument cluster.
The soot particles must be burned in the filter. The combustion is
performed when you are driving at least 60 km/h for 5 to 10 minutes. The
warning light goes out. If the warning light remains on despite this measure, the following text
appears in the display of the instrument cluster:
Engine fault Workshop!.
In this case contact a specialist garage to obtain assistance.
WARNING
Please pay attention to the traffic regulations and speed limits.
Note
It is prohibited to use biofuel and diesel fuel mixture (RME) for vehicles
with diesel engines which are fitted with diesel particle filter.
Bulbs 
The warning light  comes on for a few seconds after ignition is switched
on and goes out after several seconds.
If the warning light does not go out or comes on when driving, a bulb in the
headlights of the rear parking light or in the brake lights is defective.
The following text e.g will be displayed in the information display*:
Dipped beam front left defective!
A peep sounds as an additional warning signal.
Electromechanical 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 electromechanical power steering.
•If the yellow warning light lights up, this indicates a partial failure of the
power steering and the steering forces can be greater.
•If the red warning light lights up, this indicates a complete failure of the
power steering and the steering assist has failed (significantly higher
steering forces).
If the red warning light lights up, three peeps sound as an additional
warning signal.
Further information ⇒page 219, “Electromechanical power steering”.
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.
Control system for exhaust gases 
The warning light  comes on after the ignition has been switched on.
If the warning light does not go out after starting the engine or it lights up
or flashes when driving, a fault exists in an exhaust relevant component.
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*:
Emissions workshop!
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 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! (Engine fault workshop!)
Glow plug system  (diesel engine)
The indicator light  lights up for a cold engine when switching on the
igntion (pre-heat position) 2 ⇒ page 139. 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
 does not
come on at all or lights up continuously . Contact a specialist garage as
soon as possible to obtain assistance.

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 damages.
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 290, “Fuse assignment in
engine compartment - version 1” or ⇒page 291, “Fuse assignment in
engine 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 fan is in proper order.
Contact a specialist garage to obtain assistance.
Please also refer to the additional instructions ⇒page 253, “Cooling
system”.
The following text will be displayed in the information display*:
STOP Check coolant! Owner's manual (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 68.
•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.
