Seek help from a ŠKODA specialist garage.
ÐGlow plug system 
(diesel engine)
The warning light  comes on after the ignition has been switched on. The en-
gine can be started immediately after the pre-glow warning light goes out.
There is a fault in the glow plug system if the warning light  does not come on
at all or lights up continuously .
If the warning light  begins to flash while driving, a fault exists in the engine
control. The engine control unit allows the vehicle to run in emergency mode.

ŠKODA specialist garage. ÐEPC 
fault light (petrol engine)
If the warning light 

 lights up, there is a fault in the engine control. The engine
control unit allows the vehicle to run in emergency mode.
Seek help from a ŠKODA specialist garage. ÐDiesel particulate filter 
(diesel engine)
The diesel particulate filter separates the soot particles from the exhaust. The
soot particles collect in the diesel particulate filter where they are burnt on a reg-
ular basis.
If the warning light  lights up, soot has accumulated in the diesel particulate
filter.
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 mi-
nutes or until the warning light goes out with the 4th or 5th
gear engaged (auto-
matic gearbox: position S) when the traffic situation permits it.
The warning light  only goes out after the diesel particulate filter has been
successfully cleaned.
If the filter is not properly cleaned, the warning light  does not go out and the
warning light  begins to flash.
The following is displayed in the information display: Diesel particulate filter Owner's manual! Seek help from a ŠKODA specialist garage. WARNING
■ The diesel particle filter achieves very high temperatures. Therefore do not
park in areas where the hot filter can come into direct contact with dry grass
or other combustible materials - risk of fire!
■ Always adjust your speed to suit weather, road, region and traffic condi-
tions. The recommendations indicated by the warning light must not tempt
you to disregard the national regulations for road traffic. CAUTION
As long as the warning light  lights up, one must take into account an in-
creased fuel consumption and in certain circumstances a power reduction of the
engine. Note
■ To assist the combustion process of the soot particles, we recommend that reg-
ularly driving over short distances should be avoided. ■ Using diesel fuel with an increased sulphur content can considerably reduce the
life of the diesel particle filter. A
ŠKODA specialist garage will be able to tell you
which countries use only diesel fuel with high sulphur content. Ð Fuel reserve 
The warning light  will come on if the fuel level is less than 9 litres.
An audible signal sounds as a warning signal.
The following is displayed in the information display: Please refuel! Range ... km Note
The text in the information display goes out only after refuelling and driving a
short distance. Ð

Unlocking and locking

WARNING
Locked doors prevent unwanted entry into the vehicle from outside, for exam-
ple at road crossings. Locked doors do, however, make it more difficult for res-
cuers to get into the vehicle in an emergency - danger to life! Note
■ You can have the individual settings activated by a ŠKODA Service Partner or
you can activate them yourself with the help of the information display » page 16,
Settings. ■ In the event of an accident in which the airbags are deployed, the locked doors
are automatically unlocked in order to enable rescuers to gain access to the vehi-
cle. ■ Only the driver's door can be unlocked or locked using the key if the central
locking system fails » page 28. The other doors and the boot lid can be manually
locked or unlocked. ■ Emergency locking of the door » page 32.
■ Emergency unlocking of the boot lid » page 34. ÐSafe securing system

locks are blocked automatically if the vehicle is locked from the outside. The
warning light flashes for around 2 seconds in quick succession, afterwards it be-
gins to flash evenly at longer intervals. It is not possible to open the doors with
the door handle either from the inside or from the outside. This acts as an effec-
tive deterrent for attempts to break into your vehicle.
The safe securing system can be deactivated within 2

seconds by double locking
the vehicle.
If the safe securing system is not operating, the warning light in the driver door
flashes for about 2 seconds fast, goes out and starts to flash evenly at longer in-
tervals after about 30 seconds.
The safe securing system is activated again the next time the vehicle is unlocked
and locked.
If the vehicle is locked and the safe securing system is deactivated, the door can
be unlocked and opened from the inside by pulling on the opening lever of the
respective door. By the first pull on the opening lever, the door is unlocked. By
the second pull on the opening lever, the door is opened. WARNING
If the vehicle is locked from the outside and the safe securing system is acti-
vated, there must not be any person in the vehicle as it is then no longer pos-
sible to open either a door or a window from the inside. The locked doors
make it more difficult for rescuers to get into the vehicle in an emergency -
hazard! Note
■ The anti-theft alarm system is activated when the vehicle is locked even if the
safe securing system is deactivated. The interior monitor is however not activa-
ted. ■ After locking the vehicle, you will be informed that the safe securing system is

Unlocking and locking

Locking
The turn signal lights flash once to confirm that the vehicle has been correctly
locked.
If the doors or the boot lid remain open after the vehicle has been locked, the
turn signal lights do not flash until they have been closed.
WARNING
If the car is locked from the outside and the safe securing system is activated,
there must not be any person in the car as it is then not possible to open ei-
ther a door or a window from the inside. The locked doors make it more diffi-
cult for rescuers to get into the vehicle in an emergency - hazard! Note
■ Only operate the remote control when the doors and boot lid are closed and the
vehicle is in your line of sight. ■ To avoid the car being locked inadvertently once in the car, the lock button of the remote control must not be pressed before the key is inserted into the ig-
nition lock. Should this happen, press the unlock button
 of the remote control.
ÐSynchronisation
If the vehicle cannot be unlocked by actuating the remote control system then it
is possible that the code in the key and the control unit in the vehicle are no lon-
ger synchronised. This can occur when the buttons on the radio-operated key are
actuated a number of times outside of the operative range of the equipment or
the battery on the remote control was replaced.
This means it is necessary to synchronise the code as follows:
› press any button on the remote control key;
› pressing of the button means that the door will unlock with the key within 1 mi-
nute. Ð Anti-theft alarm system
Introductory information
The anti-theft alarm system increases the level of protection against people
seeking to break into the vehicle. The system triggers audible and visual warning
signals if an attempt is made to break into the vehicle.
