The date of manufacture
is a lso s tated on the tyre wal l (poss ibly o nl y on the

DOT ... 50 08...
means, for example, that the tyre was manufactured in the 50th week of the year 2008. If the
spare wheel*
differs from the tyres fitted to the vehicle (e.g. winter tyres or
low-profile tyres), the spare wheel* 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 quickl
y 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
y our t yre s - ris k of a n ac cid e n t re su lti ng fro m ty re d a m ag e a nd lo ss o f c ont rol 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. Ty
res 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 indivi
dual 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 essent
ial 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 abou
t the technical possibilities which exist
regarding converting or retrofitti
ng wheels, tyres and wheel trims.
WARNING
•
In case of incorrect treatment of th
e 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 wh
eel bolts for steel and light alloy wheels
is 120 Nm.

prescribed distance from your vehicl
e 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
sitting 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 th
e vehicle from unexpectedly 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 185 or the caps
⇒
page 185.
– In the case of light alloy wheels remove the wheel trim cap
⇒
page 186.
– Slacken the wheel bolts
⇒
page 186.
– Jack up the vehicle until the wheel to
be changed is clear of the ground
⇒
page 187.
– Unscrew the wheel bolts and place them on a clean surface (cloth,
paper etc.).
– Take off the wheel.– Fit on the new spare wheel* and tighten the wheel bolts slightly. –Lower the car.
– Tighten the wheel bolts firmly, al
ternately and diagonally using the
wrench* (crosswise)
⇒
page 186.
– Mount the full wheel trim/w
heel 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 173.
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. Steel and light alloy wheels must be tight-ened to a tightening torque of
120 Nm
.
– Have the defective tyre repaired as soon as possible.
WARNING
It is necessary to observe the guidelines given on
⇒page 175, “New tyres
and wheels” if the vehicle is subseq
uently 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 mu
st be replaced before chec
king 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 wrench* through the clamp, support the wheel
wrench at the tyre and pull off the wheel trim
⇒
fig. 166
.
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.

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 st
owed 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.
Note
The set of safety wheel bolts can be
obtained from a specialist garage.
Jump-startingInitial stepsYou can use the battery of another vehicl
e 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 significa
ntly 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 attent
ion 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!•
Please pay attention to the warning instructions relating to working in
the engine compartment
⇒page 160.
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 proper
ly connected to the system of the
vehicle.•
Switch off any mobile phone, pay attent
ion to the instructions for use of the
mobile phone in such a situation.•
We recommend purchasing jump-start cabl
es from Škoda Service Partners as a
Škoda original accessory or from retailers who sell branded batteries.
