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 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 retrofitti ng 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 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.
Winter tyres
The handling of your vehicle will be significantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber blend,
tread pattern). This applies in particul ar 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 char-
acteristics.
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 200.
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 ⇒page 201,
⇒ .
You can fit winter tyres of a lower speed ca tegory 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 199.
You can also fit so-called “all-year tyres” instead of winter tyres.
Please contact your specialist garage if there are any points which are not clear who
will be able to provide you with information regarding the maximum speed for your
tyres.

The fire extinguisher is located in the sheath below the driver's seat ⇒page 207,
fig. 189 (the installation position of the fire extinguisher differs on vehicles fitted
with electrically adjustable seats).
Please read carefully the instructions which are attached to the fire extin-
guisher.
The fire extinguisher must be checked by an authorised person or company annu-
ally (please observe the differing legal requirements).
WARNING
If the fire extinguisher is not correc tly attached, in case of sudden manoeu-
vres or an accident it can be “thrown” through the interior compartment and
cause injuries.
Note
•The fire extinguisher must comply with the relevant and valid legal require-
ments.
•Pay attention to the expiration date of the fire extinguisher. If the fire extin-
guisher is used after the expiration date, its proper function is no longer assured.
•The fire extinguisher is only supplied in certain countries within the scope of
delivery.
Vehicle tool kit
The car tool kit and the car jack are stowed in the left of the luggage compartment
⇒ fig. 190 below the floor covering.
The vehicle tool kit contains the following parts (depending on equipment fitted):
•Hook for pulling off a full wheel trim,
•Plastic clip for a wheel bolt cover,
•Wheel wrench,
•Assembly pin for changing wheel,
•Screwdriver with reversible blade,
•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 th e hexagon socket of the screwdriver for
tightening the wheel bolts because you will not be able to achieve the neces-
sary tightening torque with the hexagon socket - risk of accident!

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 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 wheel
Always change a wheel on a level surface as far as possible.
– Take off the full wheel trim* ⇒page 211 or the caps ⇒page 211.
– In the case of light alloy wheels remove the wheel trim cap ⇒page 211.
– Slacken the wheel bolts ⇒page 212.
– Jack up the vehicle until the wheel to be changed is clear of the ground
⇒ page 213.
– 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, al
ternately and diagonally using the
wheel wrench ⇒page 212.
– 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 199.
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 201, “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 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 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.
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.
Caution
•Use the pressure of your hand, do not knock on the full wheel trim! Heavy
knocks mainly on the points where the full wheel trim has not been inserted into
the wheel, can result in damage to the guide and centering elements of the full
wheel trim.
•First check for yourself that the th eft-deterrent wheel bolt is located
⇒ page 214, “Securing wheels against being stolen” in the hole in the area of the
valve before fitting the full wheel trim onto a steel wheel which is attached with a
theft-deterrent wheel bolt.
Wheel trim caps*
Pulling off
– Carefully ⇒fig. 192 lever off the wheel trim cap using the removal
hook .
Wheel bolts with caps*
The caps are designed to protect the wheel bolts.

outer hexagon is jutting out ⇒page 214, fig. 198 .
– Insert the wheel wrench fully onto the adapter .
– Slacken the wheel bolt, or tighten it firmly ⇒page 203.
– 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. 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 numb er 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 alwa ys 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.
•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 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 signif icantly 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 freez e 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 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.
