Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of
the tyre . This indicates the direction of rotation of the tyre, and it is essen-
tial that the tyres are fitted on to run in this direction. Only then are the
tyres able to provide the optimal properties in terms of grip, low noise,
wear-and-tear and aquaplaning.
Should it be necessary to fit on a spare wheel in exceptional cases with a
tyre not dedicated to the running direction, please adopt a cautious style
of driving as the tyre is no longer able to provide optimal grip and handling
in such a situation. This particularly important on wet roads. Please refer
to the notes ⇒page 229.
You should have the defective tyre replaced as soon as possible and
restore the correct direction of rotation on all tyres
Snow chains
Snow chains can be used only for wheel sizes 6J x 16 ET 40 or 6J x 16
ET 37. Your Škoda Dealer can provide you with more detailed information.
Snow chains must only be mounted on the front wheels.
When driving on wintry roads, snow chains improve not only traction, but
also the braking performance.
Only use fine-link snow chains . They must not project more than 15 mm
- including the chain lock.
Remove the full wheel trim if you wish to fit snow chains to the wheels.
You must take the chains off as soon as you drive on roads which are free
of snow. They adversely affect the handling of your vehicle, damage the
tyres and are rapidly destroyed. Observe the national legal requirements relating to the maximum vehicle
speed with snow chains.
Note
We recommend that you use snow chains from the Škoda range of
genuine accessories.

Spare wheel
The spare wheel is stowed in the spare wheel well in the
luggage compartment below the floor covering.
The spare wheel lies in a well under the luggage compartment floor and
is fixed in place using special screws ⇒fig. 172 . One should check the air pressure in the spare wheel (at best when
generally checking the tyre air pressures - see sign on the fuel filler flap)
to ensure that the spare wheel is always ready to use.
Unidirectional tyres*
If you have such tyres on your vehicle, please refer to the notes below:
•The spare wheel provided with a car fitted with unidirectional tyres has
different dimensions. The wheel is provided with a warning sticker.
•After fitting on the wheel, the warning sticker must not be concealed
(e.g. by the wheel trim).
•Do not drive with this spare wheel at more than 80 km/h - risk of acci-
dent. Avoid accelerating at full throttle, sharp braking and fast cornering.
•The inflation pressure for this spare wheel is identical to the inflation
pressure of the standard tyres.
•Use this spare wheel only to reach the nearest service station as it is
not intended for continuous use.
Changing a wheel
Preliminary work
The following steps should be carried out before actually
changing the wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible from the traffic flow. The place you choose
should be level.
WARNING
•The hexagon socket in the handle of the screwdriver is used for
fitting on the wheel bolts. Neve r use it for tightening the wheel
bolts because you will not be able to achieve the necessary tight-
ening torque with this tool - risk of accident!
•The factory-supplied lifting jack is only intended for your model
of vehicle. On no account attempt to lift a heavier vehicle or other
loads - risk of injury!

Subsequent steps
After changing the wheel, you must perform the following steps.
– Stow and attach the replaced wheel in the spare wheel well.
– Stow the vehicle tool kit in the space provided.
–Check the tyre pressure on the spare wheel just mounted as
soon as possible.
– Have the tightening torque of the wheel bolts checked with
a torque wrench as soon as possible. The tightening torque
must be 120 Nm.
– Have the defective tyre repaired as soon as possible.
Note
•If you find, when changing the wheel, that the wheel bolts are corroded
and difficult to turn, the bolts must be replaced before checking the tight-
ening torque.
•Drive cautiously and only at a moderate speed to a workshop where
the tightening torque can be checked.
Full wheel trim*
Removing
– Hook the clamp (found in the vehicle toolkit) into the reinforced edge of the full wheel trim.
– Push the wheel key through the clamp, support the wheel key at the tyre and pull off the wheel trim.
Installing
– First press the full wheel trim onto the wheel at the valve opening provided. Then press the full wheel trim into the
wheel in such a way that its entire circumference locks
correctly in place.
Caution
Use the pressure of your hand, do not knock on the full wheel trim! Heavy
knocks mainly on the points where the full wheel trim has not been
inserted into the wheel, can result in damage to the guide and centering
elements of the full wheel trim.WARNING
It is necessary to observe the guidelines given on ⇒page 222,
“New tyres and wheels” if the vehicle is subsequently fitted with
tyres which are different to those it was fitted with at the works.

Slackening wheel bolts
– Push the wheel wrench fully onto the wheel bolt
3).
– Grasp the end of the wrench and turn the bolt about one turn to the left ⇒fig. 175.
Tightening wheel bolts
– Push the wheel wrench fully onto the wheel bolt
3).
– Grasp the end of the wrench and turn the bolt to the right until it is tight. Note
•Do not use the hexagon socket in the handle of the screwdriver for
slackening or tightening the wheel bolts.
•apply pressure carefully with your foot to the end of the wheel wrench
if it proves difficult to slacken the wheel bolts. Hold tight on the vehicle
when doing this and ensure that you have a steady position.
Raise vehicle
You have to raise the vehicle with a lifting jack in order to
be able to take off the wheel.
3)Use the appropriate adapter for slackening and tightening the safety wheel bolts
⇒ page 235.

Changing a wheel
– Turn the wheel bolt which is farthest to the top fully out with
the hexagon socket in the screwdriver handle (car tool kit)
and place the bolt down on a clean surface ⇒page 234,
fig. 177 .
– Screw the assembly pin (car tool kit) into the vacant hole ⇒page 234, fig. 178.
– Unscrew the remaining wheel bolts as described above.
– Take off the wheel.
Fitting on wheel
– Push the spare wheel over the assembly pin.
– Screw in the wheel bolts and tighten them slightly with the aid
of the hexagon socket.
– Unscrew the assembly pin and screw in the remaining wheel bolt also slightly.
The wheel bolts must be clean and must turn easily.
The hexagon socket in the handle of the screwdriver makes it simpler to
fit on the wheel bolts. The reversible blade should be pulled out for this
step.
When fitting on unidirectional tyres, ensure that the tyres rotate in the
correct direction ⇒page 225.
Note
Do not use the hexagon socket in the handle of the screwdriver for slack-
ening or tightening the wheel bolts.
Securing wheels against being stolen
You need a special adapter for slackening the safety
wheel bolts.
– Pull off the full wheel trim/cap from the wheel hub or cap from
the safety wheel bolt.
– Push the adapter with its toothed side into the inner toothing of the safety wheel bolt right down in such a way
that only the outer hexagon is jutting out ⇒fig. 179.
– Push the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 223.
– Reinstall the full wheel trim/wheel cap after removing the adapter or place the cap onto the safety wheel bolt.

WARNING
•The non-insulated parts of the terminal clamps must never
make contact with each other. Furthermore, the cable connected to
the positive terminal of the battery must not come into contact with
electrically conducting parts of the vehicle - risk of a short circuit!
•Do not affix the jump starting cables to the negative terminal of
the discharged battery. There is the risk of detonating gas seeping
out the battery being ignited by the strong spark which results
from the engine being started.
•Run the jump-start cables so that they cannot be caught by any
rotating parts in the engine compartment.
•Do not bend over the batteries - risk of caustic burns!
•The vent screws of the battery cells must be tightened firmly.
•Keep any sources of ignition (naked flame, smouldering ciga-
rettes etc.) away from the battery - risk of an explosion!

Tow-starting a vehicle
If the engine does not start, we generally do not recommend to
tow-start your vehicle. One should attempt to start the engine using jump start cables
⇒page 236 or call on the services of the
SERVICE mobile.
If your vehicle has to be towed:
– Engage 2nd or 3rd gear with the vehicle stationary.
– Depress the clutch pedal fully and keep it depressed.
– Switch on the ignition.
– Wait until both vehicles are moving then release the clutch pedal slowly.
– Depress the clutch pedal fully when the engine fires and take the vehicle out of gear.
For technical reasons it is not possible to tow-start a car fitted with an
automatic gearbox .
Caution
Vehicles which are fitted with a catalytic converter should not be tow-
started over a distance of more than 50 metres. Unburnt fuel may get into
the catalytic converter and damage it.
