WARNINGFor the vehicle systems to function correctly, and thus for safe driving,
there must be sufficient fuel in the tank. Never drain the fuel tank com-
pletely – risk of accident!
CAUTION
Never drive until the fuel tank is completely empty! Irregular supply of fuel can
cause misfiring, which can result in damage to parts of the engine and the ex-
haust system.
Note
■ After filling up, it’s possible that during dynamic driving (e.g. numerous
curves, braking, driving downhill and climbing a steep hill) the fuel gauge indi-
cates a fraction less.■
The arrow 

The warning lights in the instrument cluster indicate certain functions or
faults.
Some warning lights can be accompanied by acoustic signals and messages in
the display of the instrument cluster.
After switching on the ignition, some warning lights light up briefly as a func-
tion test. If the tested systems are OK, the corresponding warning lights go
out a few seconds after switching on the ignition or after starting the engine.
The warning lights are located at the following positions in the instrument
cluster » Fig. 17 on page 30 .

A message will appear in the display about the affected lamp.
 Diesel particle filter (diesel)
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.

 illuminates – the filter is clogged with soot.
To clean the filter, and where traffic conditions permit »
, drive as follows for
at least 15 minutes or until the indicator light  goes out.
4. or gear 5 engaged (automatic gearbox: Position D / S).
Vehicle speed at least 70 km/h.
Engine speed between 1800-2500 rpm.
If the filter is properly cleaned, the warning light  extinguishes.
If the filter is not properly cleaned, the warning light  does not go out and
the warning light  begins to flash.
▶ You can drive on, exercising appropriate caution. Seek assistance from a spe-
cialist garage immediately.
WARNING■ Always adjust the speed and driving style to the actual weather, road, ter-
rain and traffic conditions.■
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 etc.
CAUTION■ As long as the warning light  illuminates, one must take into account an
increased fuel consumption and 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
We encourage you to avoid constant short journeys. This will improve the com-
bustion process of the soot particles in the diesel particulate filter.
