WARNING
■ During the first 500 km, new tyres do not offer optimum grip and appropri-
ate care should therefore be taken when driving - risk of accident!
■ Never drive with damaged tyres - risk of accident!
■ Only use those tyres or wheel rims which have been approved by ŠKODA for
your model of vehicle. Failure to observe this instruction will adversely affect
the road safety of your vehicle - risk of accident!
■ The maximum permissible speed for your tyres must not be exceeded under
any circumstances - risk of an accident resulting from tyre damage and loss of
control of the vehicle.
■ If the inflation pressure is too low, the tyre must perform a higher rolling re-
sistance. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and a tyre blowout. WARNING (Continued)
■ Do not, where possible, replace individual tyres but at least replace them on
both wheels of a given axle at the same time. Always fit the tyres with the
deeper tread depth to the front wheels.
■ Never use tyres if you do not know anything about the condition and age.
■ You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn down.
■ Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience
“aquaplaning” (uncontrolled
movements of the vehicle - “swimming” on a wet road surface).
■ Immediately replace damaged wheel rims or tyres.
■ Do not use summer or winter tyres that are older than 6 years or 4 years re-
spectively.
■ The wheel bolts must be clean and must turn easily. However, they must
never be treated with grease or oil.
■ If the wheel bolts are tightened to a too low tightening torque, the rim can
come loose when the car is moving - risk of accident! A tightening torque
which is too high can damage the bolts and threads and this can result in per-
manent deformation of the contact surfaces on the rim.
■ In case of incorrect treatment of the wheel bolts, the wheel can loosen
when the car is moving - risk of accident!
■ Observe the national legal regulations relating to the use of tyres and snow
chains. CAUTION
■ If a spare wheel is used that is not identical to the fitted tyres, the following
must be observed » page 190, Spare wheel.
■ The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
■ Protect the tyres from contact with oil, grease and fuel.
■ Replace any lost valve caps immediately. For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption. £

Wheels and Tyres

WARNING (Continued)
■ If the wheel has to be changed on a slope, first of all block the opposite
wheel with a stone or similar object to prevent the vehicle from unexpectedly
rolling away.
■ If the vehicle is subsequently fitted with tyres which are different to those it
was fitted with at the works, follow these guidelines »
page 189, New wheels
and tyres.
■ Always raise the vehicle with the doors closed.
■ Never position any body parts, such as arms or legs under the vehicle, while
the vehicle is raised with a lifting jack. ■ Secure the base plate of the lifting jack with suitable means to prevent pos-
sible moving. A soft and slippery ground under the base plate may move the
lifting jack, causing the vehicle to fall down. It is therefore always necessary to
place the lifting jack on a solid surface or use a wide and stable base. Use a
non-slip base (e.g. a rubber foot mat) if the surface is smooth, such as cobbled
stones, tiled floor, etc.
■ Never start the engine with the vehicle sitting on the raised jack - danger of
suffering injury.
■ Only attach the lifting jack to the attachment points provided for this pur-
pose. CAUTION
■ The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
■ If the anti-theft wheel bolt is fastened too tightly, it can cause damage to the
anti-theft wheel bolt and adapter. Note
■ The anti-theft wheel bolt set and adapter can be purchased from a
ŠKODA Serv-
ice Partner. ■ The national legal requirements must be observed when changing a wheel. ÐPreliminary work
First read and observe the introductory information and safety warn-
ings on page 196.
The following steps must be carried out before actually changing the wheel:
ä ›
In the event of a puncture, park the vehicle as far away as possible from the
flow of traffic. The place you choose should be level.
› Let all of the occupants get out.
While changing a tyre, the occupants of the
vehicle should not stand on the road (instead they should remain behind a crash
barrier).
› Switch off the engine and move the gearshift lever into
Neutral or move the
selector lever
for the automatic gearbox into position P .
› Firmly apply the
handbrake.
› If a trailer is connected, remove it.
› Remove the vehicle tool kit
» page 196 and the spare wheel »
page 190 from
the boot. Ð Changing a wheel
First read and observe the introductory information and safety warn-
ings on page 196.
Always change a wheel on a level surface as far as possible.
›
Remove the full wheel trim
» page 191 or caps » page 191.
› In the case of light alloy wheel rims remove the wheel trim cap
» page 191.
› First of all slacken the anti-theft wheel bolt and then the other wheel
bolts » page 198.
› Jack up the vehicle until the wheel that needs changing is clear of the
ground » page 199.
› Unscrew the wheel bolts and place them on a clean surface (cloth, paper, etc.).
› Remove the wheel.
› Attach the spare wheel and slightly screw on the wheel bolts.
› Lower the vehicle.
› Alternately tighten the wheel bolts opposite each other using the wheel
wrench (crosswise) and then tighten the anti-theft wheel bolt » page 198.
› Replace the wheel trim or the caps. Note
■ All bolts must be clean and must turn easily.
■ Under no circumstances grease or oil the wheel bolts!
■ When fitting unidirectional tyres, ensure that the direction of rotation is cor-
rect »

Subsequent steps
First read and observe the introductory information and safety warn-
ings on page 196.
The following steps must also be performed after changing the wheel.
›
Stow and attach the replaced wheel in the spare wheel well using a special
screw » page 190 .
› Stow the vehicle tool kit in the space provided.
› Check the tyre pressure
on the installed spare wheel as soon as possible.
› Have the
tightening torque of the wheel bolts checked with a torque wrench
as soon as possible.
› Change the damaged wheel or consult a ŠKODA specialist garage about repair
possibilities. Note
■ If it is determined that the wheel bolts are corroded and difficult to turn when
changing the wheel, the bolts must be replaced before checking the tightening
torque. ■ Drive cautiously and only at a moderate speed until the tightening torque has
been checked. ÐLoosening and tightening wheel bolts

Changing a wheel: Jacking points
for positioning lifting jack Fig. 175
Attach lifting jack
First read and observe the introductory information and safety warn-
ings on page 196.
Position the lifting jack by selecting the jacking point that is closest to the faulty
wheel
» Fig. 174. The jacking point is located directly below the engraving in the
lower sill.
› Position the lifting jack below the jacking point and move it up until its claw is
positioned directly below the vertical web of the lower sill.
› Align the lifting jack so that its claw grasps the web
» Fig. 175 -
 below the
embossing in the side surface of the lower sill.
› Ensure that the entire surface of the lifting jack base plate rests on level
ground and is located in a vertical position to the area » Fig. 175 where the claw
grasps the web.
› Continue turning up the jack until the wheel is just about lifted off the ground. Ð
ä Securing wheels against theft
Fig. 176
Principle sketch: Anti-theft
wheel bolt with adapter
First read and observe the introductory information and safety warn-
ings on page 196.
The anti-theft wheel bolts on vehicles fitted with them (one anti-theft wheel bolt
per wheel) can only be loosened or tighten up by using the adapter provided.
›
Pull off the full wheel trim from the wheel rim or the cap from the anti-theft
wheel bolt.
› Insert the adapter B
» Fig. 176 with its toothed side fully into the inner tooth-
ing of the safety wheel bolt A
until the stop so that only the outer hexagon is
jutting out.
› Push the wheel wrench onto the adapter B
up to the stop.
› Loosen or tighten the wheel bolt
» page 198.
› After removing the adapter, reinstall the full wheel trim or place the cap onto
the anti-theft wheel bolt.
› Have the
tightening torque checked with a torque wrench as soon as possible.
It is advisable to make a note of the code number hammered into the rear side of
the adapter or the rear side of the anti-theft wheel bolt. This number can be used
to purchase a replacement adapter from a
ŠKODA Service Partner, if necessary.
We recommend that you always carry the adapter for the wheel bolts with you in
the vehicle. It should be stowed in the vehicle tool kit. Ð
