Diesel particle filter*  (diesel engine)
If the warning light  comes on, this means that soot has accumulated in the diesel
particle filter because of the frequent short distances. In order 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
minutes or until the warning light goes ou t with the 4th or 5th gear engaged (auto-
matic gearbox: position S) when the traffi c situation permits it. This increases the
exhaust temperature and the soot deposited in the diesel particle filter is burnt.
Always pay attention to the valid speed limits ⇒.
The warning light
 goes out after the successful cl eaning of the diesel particle
filter.
If the filter is not properly cleaned, the warning light
 does not go out and the
warning light  begins to flash. Engine fault Workshop! is shown in the informa-
tion display*. Afterwards the engine cont rol unit shifts the engine into the emer-
gency mode, which only has a reduced powe r output. After switching the ignition
off and on again the warning light
 comes on.
Have the vehicle inspected without delay by your specialist garage.
WARNING
•If you do not pay attention to the wa rning light coming on and the corre-
sponding descriptions and warning notes, this may result in injuries or
major vehicle damage.
•Always adjust your speed to suit weather, road, region and traffic condi-
tions. The route indicated by the warn ing light must not tempt you to disre-
gard the national regulations for road traffic.
Caution
As long as the warning light  lights up, one must take into account an increased
fuel consumption and in certain circumst ances a power reduction of the engine.

Unlocking and locking
Key
The vehicle is supplied with two keys. Depending on the equipment fitted, your
vehicle can be equipped with keys without remote control ⇒fig. 20 ; with keys with
light* ⇒page 35, fig. 22 or with keys with radio remote control* ⇒fig. 21 .
Key ring
The key ring ⇒fig. 20 only has the key number on it which is essential for producing
other keys. This number can be used to order replacement keys from the Škoda
Service Partners. The
key ring with the number should be separately and securely kept in safe
keeping since keys can only be replaced if th ey are lost or damaged by giving this
number. You should also therefore give this key ring to the purchaser when selling
the vehicle.
WARNING
•Always withdraw the key whenever you leave the vehicle - even if it is
only for a short time. This is particularly important if children are left in the
vehicle. The children might otherwise st art the engine or operate electrical
equipment (e.g. power windows) - risk of injury!
•Do not withdraw the ignition key from the ignition lock until the vehicle
has come to a stop. The steering lock might otherwise engage unintention-
ally - risk of accident!
Caution
•Each key contains electronic components; therefore protect them against mois-
ture and severe shocks.
•Keep the groove of the keys absolutely cl ean as impurities (textile fibres, dust
etc.) have a negative effect on proper op eration of the keys and the ignition lock.
Note
Please approach a Škoda Service Partner if you lose a key since he can obtain a new
one for you.
