the engine compartment .
If the coolant level and fan fuse are both OK but the indicator light  is still
illuminated ,  do not continue your journey!
Seek help from a specialist garage.WARNING■ Carefully open the coolant expansion bottle. If the engine is hot, the cool-
ing system is pressurized - risk of scalding! It is therefore best to allow the
engine to cool down before removing the cap.■
Do not touch the radiator fan. The radiator fan may switch itself on auto-
matically even if the ignition is off.
CAUTION
■ Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.■
Never cover the radiator - there is a risk of the engine overheating.

 Diesel particulate filter (diesel engine)
Read and observe
on page 33 first.
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
regular basis.
If the indicator light 

To clean the filter, and where traffic conditions permit »
, drive as follows for
at least 15 minutes or until the indicator light  goes out.
4th or 5th gear selected (automatic gearbox: position S).
Vehicle speed at least 70 km/h.
Engine speed between 1800 - 2500 rpm.

nates .
Seek assistance from a specialist garage immediately.
WARNING■ The diesel particulate filter reaches very high temperatures - there is a
fire hazard and serious injury could be caused. Therefore, never stop the
vehicle at places where the underside of your vehicle can come into contact
with flammable materials such as dry grass, undergrowth, leaves, spilled
fuel or such like.■
Always adjust your speed to suit weather, road, region and traffic condi-
tions. The recommendations indicated by the indicator light must not
tempt you to disregard the national regulations for road traffic.
CAUTION
■ As long as the indicator light  lights up, one must take into account an in-
creased fuel consumption and in certain circumstances a power reduction of
the engine.■
Using diesel fuel with an increased sulphur content can considerably reduce
the life of the diesel particle filter. A ŠKODA partner will be able to tell you
which countries use diesel fuel with a high sulphur content.
Note
■ To assist the combustion process of the soot particles in the filter, we recom-
mend that regularly driving short distances be avoided.■
If the engine is turned off during the filter cleaning process or shortly after-
wards, the cooling fan may turn on automatically for a few minutes.
 Fuel reserve

CAUTION
Never drive until the fuel tank is completely empty! The irregular supply of fuel
can cause misfiring. This can result in considerable damage to parts of the en-
gine and the exhaust system.
Note
The text in the display goes out only after refuelling and driving a short dis-
tance.37Instruments and Indicator Lights

Current fuel consumption
The current fuel consumption level is displayed in litres/100 km 1)
. You can use
this information to adapt your driving style to the desired fuel consumption.
The display appears in litres/hour if the vehicle is stationary or driving at a low
speed 2)
.
Average fuel consumption
The average fuel consumption since the memory was last erased is displayed
in litres/100 km 1 )
.
If you wish to determine the average fuel consumption over a certain period of
time, you must set the memory at the start of the new measurement to
zero » page 42 , Memory . After erasing the memory, no value is displayed until
you have driven approx. 300 m.
The display is updated regularly while you are driving.
Range
The range indicates the distance you can still drive with your vehicle based on
the level of fuel in the tank and the same style of driving as before.
The display is shown in steps of 10 km. After lighting up of the indicator light 
the display is shown in steps of 5 km.
The fuel consumption over the last 50 km is used to calculate the information.
The range will increase if you drive in a more economical manner.
If the memory is set to zero (after disconnecting the battery), a fuel consump-
tion of 10 l./100 km is calculated for the range; afterwards the value is updated
according to the style of driving.
Distance travelled
The distance travelled since the memory was last erased is displayed.
If you want to measure the distance travelled from a particular moment in time
on, at this moment, reset the memory by setting the button to zero » page 42,

Your car is equipped with a central locking system.
The central locking system allows you to lock and unlock all doors, the fuel fill-
er flap and tailgate at the same time based on the current setting 1)
.
The safe securing system » page 51 is integrated in the central locking sys-
tem. Once the car is locked from the outside, the door locks 2)

› The doors, the boot lid and the fuel filler flap are unlocked.
› The interior light, which is switched by the door contact, comes on.
› The safe securing system is switched off 2)

› The anti-theft alarm system is activated.
Displaying an error If the indicator light in the driver's door initially flashes quickly for around 2
seconds, and then lights up for 30 seconds without interruption before flash-
ing again slowly, you will need to seek the assistance of a specialist garage.WARNING■ Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury and accidents!■
When leaving the vehicle, never leave persons who are not completely in-
dependent, such as children, unattended in the vehicle. The children might,
for example, release the handbrake or take the vehicle out of gear. The ve-
hicle could then start to move – risk of injury and accidents! These individu-
als might also not be able to leave the vehicle on their own or to help
themselves. Can be fatal at very high or very low temperatures!
■
If the car is locked from the outside and the safelock system is switched
on, there must not be any person in the car as it is then not possible 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 – risk to
life.
Note
■ When leaving the vehicle, always check if it is locked.■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 vehicle.■
Upon failure of the central locking system the key can be used only to unlock
and lock the driver's door. The other doors and the boot lid can be emergency
locked or released. ■ Emergency locking of the door » page 212.

48Operation

Dynamic cornering lights
The cone of light in front of the vehicle is adjusted to the steering angle so
that the road in the curve is illuminated. This function is active at speeds
greater than 10 km.h and in all AFS modes.
Tourist lights (Travel mode)
This mode makes it possible to drive in countries with opposing traffic system
(driving on the left/right) without dazzling the oncoming vehicles.
When this mode is active, the above-mentioned modes and the side swivel of
the headlights is deactivated.
This mode can be enabled or disabled via the Maxi DOT display in the Travel
mode » page 45 , Lights and Visibility menu option.WARNINGIf the AFS system is defective, the headlights are automatically lowered to
the emergency position, which prevents a possible dazzling of oncoming
traffic. This reduces the cone of light in front of the vehicle. Drive carefully
and visit a specialist garage as soon as possible.
Note
When the “tourist light” mode is active, the warning light  flashes for 10 sec-
onds each time the ignition is switched on.
