Wheels and Tyres
154
The date of manufacture is also stated on the tyre wall (possibly only on the inside of
wheel):
DOT ... 20 09...
means, for example, that the tyre was ma nufactured in the 20th week of the year 2009.
Any spare wheel which differs from the tyres fitted to the vehicle (e.g. winter tyres or
low-profile tyres) should only be used for a short time in the event of a puncture and
when adopting an appropriately cautious styl e of driving. It should be replaced as
quickly as possible by a normal wheel.
WARNING

Only use those tyres or wheel rims which have been approved for your
model of Škoda Auto vehicle. Failure to observe this instruction will adversely
affect the road safety of your vehicle - risk of accident! Approval and licensing
of your vehicle on public roads ma y also become void as a result.

You must on no account drive at a high er speed than is permissible for your
tyres - risk of an accident resulting from tyre damage and loss of control over
your vehicle.

Tyres which are 6 years old or more should only be fitted in exceptional
cases and when adopting an approp riately cautious style of driving.

Never fit tyres which have already been used without having adequate
knowledge of their previous history. Tyre s age even if they have not been used
at all or only very little. A spare tyre must only be used in exceptional cases and
only then when adopting an appropriately cautious style of driving.

Do not, where possible, replace individu al 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.For the sake of the environment
Old tyres must be disposed of in conf ormity with the appropriate regulations.
Note
It is not normally possible to fit wheels from other models of cars for technical reasons.
This may also apply in certain circumstance s to the wheels of the same type of
vehicle.Wheel boltsWheels and wheel bolts are matched to each other in terms of design. Each time you
fit other wheels - e.g. light alloy wheels or wheels with winter tyres - you must therefore
also use the matching wheel bolts of the corr ect length and shape of spherical cap. This
is essential to ensure that the wheels are tightly fitted and that the brake system oper-
ates properly.
If you retrofit wheel trims (or have this done), please also ensure that an adequate
flow of air remains assured for cooling the brake system.
The authorised Škoda Service Partners are instructed in the technical possibilities
which exist regarding converting or retrofitting tyres, wheels and wheel trims.
WARNING

In case of incorrect treatment of the wheel bolts, the wheel can loosen when
the car is moving - risk of accident!

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
lossen 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 permanent
deformation of the contact surfaces on the rim.Caution
The prescribed tightening torque of the wheel bolts for steel and light alloy wheels is
120 Nm.

–Take the vehicle tool kit  page 159 and the spare wheel* page 160 out of the
luggage compartment.
WARNING

If you find yourself in flowing traffic switch on the hazard warning lights
system and place the warning triangle on the side of the road at the prescribed
distance from your vehicle while observing all national legal provisions. In this
way you are protecting not only yourself but also other road users.

Never start the engine with the vehicle si tting on the raised jack - danger of
suffering injury.Caution
If you have to change a wheel on a slope first block the opposite wheel with a stone or
similar object in order to secure the vehicle from unexpec tedly rolling away.
Note
Comply with the national legal regulations.Changing a wheelAlways change a wheel on a level surface as far as possible.
– Take off the full wheel trim* page 163 or the caps page 163.
– In the case of light alloy wheels remove the wheel trim cap page 163.
– First of all slacken the safety wheel bo lt* and afterwards the other wheel bolts
 page 164.
– Jack up the vehicle until the wheel to be changed is clear of the ground page 164.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper etc.).
– Take off the wheel.
– Fit on the spare wheel and ti ghten the wheel bolts slightly.
–Lower the car. – Tighten the wheel bolts firmly, alternatel
y and diagonally using the wheel wrench
(crosswise) and last the safety wheel bolt* page 164.
– Mount the full wheel trim/wheel trim cap or the caps.
Note

All bolts must be clean and must turn easily.

You must never grease or oil the wheel bolts!

When fitting on unidirectional tyres, ensu re that the tyres rotate in the correct
direction page 151.
Subsequent stepsAfter changing the wheel, you mu st 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. Steel and light alloy wheels must be tightened to a tightening
torque of 120 Nm.
– Change the damaged wheel or consult a sp ecialist garage about possibilities for
getting repairs done.
WARNING
It is necessary to observe the guidelines given on page 153 if the vehicle is
subsequently fitted with tyres which are di fferent to those it was fitted with at
the works.
Note

If you find, when changing the wheel, that the wheel bolts are corroded and diffi-
cult to turn, the bolts must be replaced before checking the tightening torque.

Drive cautiously and only at a moderate speed to a workshop where the tightening
torque can be checked.

Technical Data

Not positioning the lifting jack* at the specified points can result in damage
to the vehicle. The jack can also slip off if it does not have sufficient grip - risk of
injury!

It is important to support the vehicle with suitable supporting blocks if you
wish to work under the lifted vehicle - risk of injury!
Securing wheels against being stolen*
You need a special adapter for sl ackening the safety wheel bolts.– Pull off the full wheel trim/cap from the wheel hub or cap from the safety wheel
bolt.
– Insert the adapter with its toothed side fu lly into the inner toothing of the safety
wheel bolt right down in such a way that only the outer hexagon is jutting out
 fig. 139 .
– Insert the wheel wrench* fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly page 164.
– Reinstall the full wheel trim/wheel cap afte r removing the adapter or place the cap
onto the safety wheel bolt.
– Have the tightening torque checked with a torque wrench as soon as possible.
Steel and light alloy wheels must be tightened to a tightening torque of 120 Nm .The safety wheel bolts on vehicles fitted wi
th them (one safety wheel bolt per wheel)
can only be loosened or tighten up by using the adapter provided.
It is meaningful to note th e code number hammered into the rear side of the adapter
or the rear side of the safety wheel bolts. You can obtain a replacement adapter from
an authorised Škoda Service Partner, if necessary, by quoting this number.
We recommend that you always carry the ad apter for the wheel bolts with you in the
vehicle. It should be stow ed in the vehicle tool kit.
Caution
Damage can occur to the adapter and safety wh eel bolt if the safety wheel bolt is tight-
ened up too much.
Note
The set of safety wheel bolts can be obta ined from an authorised Škoda Service
Par tner.Jump-startingInitial stepsYou can use the battery of another vehicle fo r jump-starting yours if the engine does
not start because the battery on your vehicle is flat. You will require jump-start cables
for this purpose.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the battery
supplying the power must not be significantly less than the capacity of the discharged
battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and insu-
lated terminal clamps. Please pay attention to the manufacturer's instructions.
Positive cable - colour coding in the majority of cases red.
Negative cable - colour coding in the majority of cases black.
