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 regula-
tions.
Note
It is not normally possible to fit wheels from other models of cars for tech-
nical reasons. This may also apply in certain circumstances to the wheels
of the same type of vehicle.
Wheel bolts
Wheels 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 Škoda Service Partners are instructed in the technical possibilities
which exist regarding converting or retrofitting wheels, tyres and wheel
trim.
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 tight-
ening torque which is too high can damage the bolts and threads
and this can result in perman ent 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.
Winter tyres
The handling of your vehicle will be significantly improved when driving on
wintry roads and at temperatures below 7 °C if you fit winter tyres.
Summer tyres do not offer the same grip on ice and snow at a temperature
below 7 °C because of their construction (width, rubber blend, tread
pattern). This applies in particular to vehicles which are equipped with
low-profile tyres or high-speed tyres (code index H, V or W on wall of
tyre).
Winter tyres must be mounted on all four wheels to obtain the best
handling characteristics.
You must only fit those types of winter tyre which are approved for your
vehicle. The permissible sizes of winter tyres are stated in your vehicle
documents. Approvals may differ because of national legislation.

Vehicle tool kit
The vehicle tool kit and the lifting jack are stored in a locable plastic box
in the spare wheel ⇒fig. 166 . There is also space here for the removable
ball for the trailer towing device.
The vehicle tool kit contains the following parts (depending on equipment
fitted):
•To r x w r e n c h ,
•Wheel wrench,
•Hook for pulling off a full wheel trim,
•Towing eye,
•Adapter for the wheel bolts lock.
After using the lifting jack, screw in the arm of the lifting jack fully before
placing it back in its stowage area.
WARNING
•The hexagon socket in the handle of the screwdriver should
only be used to fit on the wheel bolts. Never use the hexagon
socket of the screwdriver for tightening the wheel bolts because
you will not be able to achieve the necessary tightening torque with
the hexagon socket - 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!
•Ensure that the vehicle tool kit is safely attached in the luggage
compartment.
Tyre repair kit*
The tyre repair kit is intended for the repair of minor tyre defects. The tyre
repair kit contains a compressor, inflation bottle, operating instructions
and accessories.
The repair with the tyre repair kit is not at all intended to replace a
permanent repair on the tyre, this repair only serves to reach the next
workshop. The repair can be undertaken on the vehicle immediately.
Please read the attached instructions carefully before the repair.
The tyre repair kit is located in the luggage compartment.

–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 227,
“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 tight-
ening torque.
•Drive cautiously and only at a moderate speed to a workshop where
the tightening 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. 168 .
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.

– Slacken the wheel bolt, or tighten it firmly ⇒page 241.
– 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 with a torque wrench as
soon as possible. Steel and light alloy wheels must be tight-
ened 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 Škoda Service Partner, 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 Škoda Service
Partner.
Jump-starting
Initial steps
You 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 insulated 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 210.
Note
•There must not be any contact between the two vehicles otherwise
current may flow as soon as the negative terminals are connected.
