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.
Škoda dealers 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 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 V, W or Y on wall of tyre).
Winter tyres must be mounted on all four wheels to obtain the best
handling characteristics.
Only use radial winter tyres.
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.
Please remember that the tyres should be inflated to 20 kPa (0.2 bar)
more than is the case for summer tyres ⇒page 226.
Winter tyres no longer offer the same winter performance once the tyre
tread has worn down to a depth of about 4 mm.
Ageing also causes winter tyres to lose most of their winter performance
properties - even in cases where the remaining tread depth is still clearly
more than 4 mm.
Speed restrictions apply to winter tyres as well as to summer tyres
⇒ .
You can fit winter tyres of a lower speed category to your vehicle provided
that you also do not drive faster than the permissible maximum speed for
such tyres, even if the possible maximum speed of your vehicle is higher.
The corresponding tyre category can damage the tyres when exceeding
the permissible maximum speed.
Please pay attention to the notes if you decide to fit winter tyres
⇒ page 225.

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.
Spare wheel
The spare wheel is stowed in the spare wheel well in the
luggage compartment below the floor covering.
The spare wheel lies in a well in the luggage compartment under floor
covering and is fixed in place using special screws ⇒fig. 177 .
One should check the inflation pressure in the spare wheel (at best when
generally checking the tyre air pressures - see sign on the fuel filler flap
⇒ page 226) to ensure that the spare wheel is always ready to use.
Unidirectional tyres*
If you have such tyres on your vehicle, please refer to the notes below:
•The spare wheel provided with a car fitted with unidirectional tyres has
different dimensions. The wheel is provided with a warning sticker.
•After fitting on the wheel, the warning sticker must not be concealed
(e.g. by the wheel trim).

•Do not drive with this spare wheel at more than 80 km/h - risk of acci-
dent. Avoid accelerating at full throttle, sharp braking and fast cornering.
•The inflation pressure for this spare wheel is identical to the inflation
pressure of the standard tyres.
•Use this spare wheel only to reach the nearest service station as it is
not intended for continuous use.
Changing a wheel
Preliminary work
The following steps should be carried out before actually
changing the wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible from the traffic flow. The place you choose
should be level.
– Have all the occupants get out. While changing a wheel, the
occupants of the vehicle should not stand on the road (it is
better behind a crash barrier).
– Apply the handbrake firmly.
– Engage 1st gear or if your vehicle is fitted with an automatic
gearbox, position the selector lever into position P .
– If a trailer is coupled, uncouple it.
– Take the vehicle tool kit and the spare wheel ⇒ page 237
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 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 the vehicle from unexpect-
edly rolling away.
Note
Comply with the national legal regulations.
Changing a wheel
Always change a wheel on a level surface as far as possible.
– Take off the full wheel trim* ⇒page 239 or the caps
⇒ page 241.
– In the case of light alloy wheels remove the wheel trim cap ⇒page 240.
– Slacken the wheel bolts ⇒page 241.

Breakdown assistance239
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
– Jack up the vehicle until the wheel is clear of the ground
⇒page 242.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper etc.).
– Take off the wheel.
– Fit on the spare wheel and tighten the wheel bolts slightly.
– Lower the car.
– Tighten the wheel bolts firmly, alternately and diagonally using the wheel wrench ⇒page 241.
– 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 225.
Subsequent steps
After 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 228,
“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*
Removing
– Hook the clamp (found in the vehicle toolkit) into the reinforced edge of the full wheel trim.
– Push the wheel key through the clamp, support the wheel key at the tyre and pull off the wheel trim.

WARNING
Slacken the wheel bolts only a little (about one turn) as long as the
vehicle has not yet been jacked up - risk of an accident!.
Note
•Do not use the hexagon socket in the handle of the screwdriver for
slackening or tightening the wheel bolts.
•apply pressure carefully with your foot to the end of the wheel wrench
if it proves difficult to slacken the wheel bolts. Hold tight on the vehicle
when doing this and ensure that you have a steady position.
Raise vehicle
You have to raise the vehicle with a lifting jack in order to
be able to take off the wheel.
– Position the lifting jack by selecting the jacking point - lower sill - which is closest to the wheel to be removed ⇒fig. 181.
– 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 of the lower sill and the moving base plate of the jack is resting flat
against firm ground.
– Turn the lifting jack up further until the wheel is just clear of the ground.
Ground below the lifting jack which is soft and slippery can cause the
vehicle to slip off the jack. It is therefore always necessary to place the lift-
ingjack on a solid surface. Use a wide, stable base, if necessary. Use a
non-slip base (e.g. a rubber foot mat) if the surface is smooth, such as
cobbled stones, a tiled floor,etc.
WARNING
•Always raise the vehicle with the doors closed - risk of injury.
•Take suitable measures to prevent the base of the lifting jack
from slipping off - risk of injury!
•Place the lifting jack only on a solid and even surface.
•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!
•Never start the engine if the vehicle is lifted - risk of accident.
•Never lie under the vehicle if the vehicle is only lifted with the
vehicle lifting jack.Fig. 181 Changing a
wheel: Points for posi-
tioning car jack

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
•It is important to support the vehicle with suitable supporting
blocks if you wish to work under the lifted vehicle - risk of injury!
Taking off and fitting on wheel
After you have slackened the wheel bolts and have raised the car
with the car jack, replace the wheel as follows:
Changing a wheel
– Turn the wheel bolt which is farthest to the top fully out with
the hexagon socket in the screwdriver handle (car tool kit)
and place the bolt down on a clean surface ⇒ fig. 182.
– Screw the assembly pin (car tool kit) into the vacant hole ⇒fig. 183.
– Unscrew the remaining wheel bolts as described above.
– Take off the wheel.
Fitting on wheel
– Push the spare wheel over the assembly pin.
WARNING (continued)

– Screw in the wheel bolts and tighten them slightly with the aid
of the hexagon socket.
– Unscrew the assembly pin and screw in the remaining wheel bolt also slightly.
The wheel bolts must be clean and must turn easily.
The hexagon socket in the handle of the screwdriver makes it simpler to
fit on the wheel bolts. The reversible blade should be pulled out for this
step.
When fitting on unidirectional tyres, ensure that the tyres rotate in the
correct direction ⇒ page 231.
Note
Do not use the hexagon socket in the handle of the screwdriver for slack-
ening or tightening the wheel bolts.
Securing wheels against being stolen
You need a special adapter for slackening the safety
wheel bolts.
– Pull off the full wheel trim/cap from the wheel hub or cap from
the safety wheel bolt.
– Push the adapter with its toothed side into the inner toothing of the safety wheel bolt right down in such a way
that only the outer hexagon is jutting out ⇒fig. 184.
– Push the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 230.
– 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. The tightening torque must be 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 dealer, 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 your Škoda dealer.
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. Never perform a jump start, if one of the batteries is
frozen - risk of explosion! Also after thawing there is a risk of
caustic burns due to leaking battery acid. Replace a frozen battery.
•Please pay attention to the warning instructions relating to
working in the engine compartment ⇒page 209.
Note
•There must not be any contact between the two vehicles otherwise
current may flow as soon as the negative terminals are connected.
