Technical Data The date of manufacture is also stated on the tyre wall (possibly only on the inside
of wheel).
DOT ... 22 09...
means, for example, that the tyre was manufactured in the 22nd 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 style 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 licencing of your vehicle on public roads may also become void as a
result.
•
You must on no account drive at a higher 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 appropriately cautious style of driving.
•
Never fit tyres which have already been used without having adequate
knowledge of their previous history. Tyres 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 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.For the sake of the environment
Old tyres must be disposed of in conformity 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 circumstances 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 correct length and shape of
spherical cap. This is essential to ensure that the wheels are tightly fitted and that
the brake system operates 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 specialist garages are informed about the technical possibilities which exist
regarding converting or retrofitting wheels, tyres 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 rims.Caution
The prescribed tightening torque of the wheel bolts for steel and light alloy wheels
is 120 Nm.

– Tighten the wheel bolts firmly, alternately and diagonally using the
wheel wrench ⇒page 211.
– 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, ensure that the tyres rotate in the correct
direction ⇒page 198.
Subsequent stepsAfter 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 for steel and light
alloy wheels must be 120 Nm.
– Have the defective tyre repaired as soon as possible.
WARNING
It is necessary to observe the guidelines given on ⇒page 200, “New tyres
and wheels” if the vehicle is subsequently fitted with tyres which are
different to those it was fitted with at the works.
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 tightening torque.
•
Drive cautiously and only at a moderate speed to a workshop where the tight-
ening torque can be checked.
Full wheel trim*Pulling off
– Hook the clamp found in the vehicle tool kit into the reinforced edge
of the full wheel trim.
– Push the wheel key through the clamp, support the wheel key on the
tyre and pull off the wheel trim ⇒fig. 190.
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.

Technical Data
– 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 fully into the inner toothing
of the safety wheel bolt right down in such a way that only the
outer hexagon is jutting out ⇒page 212, fig. 194.
– Insert the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 211.
– Reinstall the full wheel trim/wheel cap after removing the adapter or
place the cap onto the safety wheel bolt.
–Have the tightening torque checked w i t h a t o rq u e w re n c h a s s o o n a s
possible. Steel and light alloy wheels must be tightened to a tightening
torque of 120 Nm.The safety wheel bolts on vehicles fitted with them (one safety wheel bolt per
wheel) can only be loosened or tighten up by using the adapter provided.
It is meaningful to note the 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 a specialist garage, if necessary, by quoting this number.
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.
Caution
•
Damage can occur to the adapter and safety wheel bolt if the safety wheel bolt
is tightened up too much.
•
On steel wheels, the theft-deterrent wheel bolt must always be installed in the
hole, which is close to the valve. Otherwise the full wheel trim cannot be mounted
and the full wheel trim can be damaged during the assembly.Note
The set of safety wheel bolts can be obtained from a specialist garage.
Jump-startingInitial stepsYou can use the battery of another vehicle for 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.
WARNING
•
A discharged battery may already freeze at temperatures just below 0°C.
In case of frozen battery carry out no jump-starting - risk of explosion! Also
after thawing of the battery there is a risk of caustic burns due to leaking
acid. Replace the frozen battery.
•
Please pay attention to the warning instructions relating to working in
the engine compartment ⇒page 185.Note
•
There must not be any contact between the two vehicles otherwise current may
flow as soon as the negative terminals are connected.
•
The discharged battery must be properly connected to the system of the
vehicle.
•
Switch off any installed telephone and also pay attention to the instructions for
use of the telephone in such a situation.
