Engine oil
Check engine oil level
The dipstick indicates the level of oil in the engine.
Checking the oil level
– Park the vehicle on a horizontal surface.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 225.
– Wait a few minutes and pull out the oil dipstick.
– Wipe off the dipstick with a clea n cloth and insert it again fully.
– Then withdraw the dipstick ag ain and read off the oil level.
Oil level within range
– You must not top up the oil. Oil level within range
–You
may top up the oil. It is possible that the oil level may then be
within range after doing this.
Oil level within range
–You must top up the oil ⇒page 228. It is sufficient, once this is done,
to keep the oil level within range .
It is normal for the engine to consume oi l. The oil consumption may be as much as
0.5 ltr./1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. The oil consumpt ion may be slightly higher than this
during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range - but not above this,
if the engine has been operating at hi gh loads, for example during a lengthy
motorway trip during the summer months, towing a trailer or negotiating a high
mountain pass.
The warning light in the instrument cluster* will indicate ⇒page 36, “Engine oil
pressure ” whether the oil level is too low. In this case, check the oil level as soon
as possible. Top up with an appropriate quantity of oil.
Caution
•The oil level must on no account ex tend beyond the range . Danger of
damaging the catalytic converter.
•Do not continue your journey if for some reason it is not possible under the
conditions prev ailing to top up with oil. Switch of the engine and contact and
obtain professional assistance from a specialist garage.

also protects the cooling and heating system from corrosion. It also prevents the
formation of scale and significantly increases the boiling point of the coolant.
You must therefore not reduce the concentr
ation of antifreeze agent in the coolant
by adding water, also not during the summ er months or in countries with a warm
climate. The concentration of coolant additive in the coolant must be at least
40%.
You can increase the amount of antifreeze in the coolant if a higher concentration
of antifreeze is necessary for climatic reasons but only up to 60% (antifreeze
protection down to approx. -40°C). The an tifreeze protection tails off above that
concentration.
Vehicles exported to countries with a co ld climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant wh ich offers antifreeze protection down to
about -35°C. In these countries the concentr ation of coolant additive should be at
least 50 %.
Coolant
The cooling system is factory-filled with co olant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the same c oolant additive - G12 PLUS-PLUS (purple
in colour) for toppi ng up the system.
Please contact your Škoda Service Partner if you have any questions regarding the
coolant or if you wish to fill up with a different coolant.
Your Škoda Service Partner can also suppl y you with the correct coolant additives.
Caution
•Other coolant additives may cause operational problems which, in partic-
ular, involves significantly redu cing the anticorrosion effect.
•Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th is, result in major engine damage.
Inspecting the coolant level
The coolant expansion bottle is located in the engine compartment on
the right.
– Switch the engine off.
– Open the bonnet ⇒page 224.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 213.
The coolant level when the engine is cold must lie between the
(MIN) and (MAX) markings. The level may also rise slightly above
the (MAX) marking when the engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light
in the instrument cluster ⇒page 37, “Coolant temperature/ Coolant quantity ”.
We nevertheless recommend in specting the coolant level directly at the reservoir
from time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. You
should not merely top up the coolant in the reservoir. It is also important to have
the cooling system inspected without delay by a specialist garage.

Radiator fan
The radiator fan may switch on suddenly.
The radiator fan is driven by an electr ic motor and controlled according to the
coolant temperature.
The radiator fan may continue running fo r up to 10 minutes after the engine has
been switched off - even if the ignition is also off. It may also switch on suddenly
after a certain time, if
•the coolant temperature ha s risen because of an accumulation of heat or
•the warm engine compartment is heated up additionally by strong sunlight.
WARNING
You must therefore be aware when work ing in the engine compartment that
the fan may switch on suddenly - risk of injury!
Brake fluid
Inspecting the brake fluid level
The brake fluid reservoir is located on the left of the engine compartment.
The brake fluid reservoir on right-hand steering models is positioned on
the other side of the engine compartment.
– Switch the engine off.
– Open the bonnet ⇒page 224.
– Inspect the brake fluid level in the reservoir ⇒fig. 214 . The level must
be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear
and automatic adjustment of the br ake pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid level
drops significantly within a short time or if it drops below the “MIN” marking. If the
brake fluid level is too low, this is indicated by the warning light ⇒page 40, “Brake
system ” lighting up in the instru ment cluster. In this case stop immediately and
do not drive any further! Obtain professional assistance.
WARNING
•Read and observe the warning notes ⇒page 225, “Working in the engine
compartment” before working in the engine compartment.
•If the fluid level has dropped below the MIN marking, do not drive any
further - risk of accident! Contact a Škoda dealer to obtain professional
assistance.
Replacing brake fluid
Brake fluid absorbs moisture. This causes the fluid to absorb moisture from the
surrounding air over a period of time. Excessive water in the brake fluid may be the
cause of corrosion in the brake system. Th e water content also lowers the boiling
point of the brake fluid. This is why brake fluid must be replaced every two
years.
One may only use new genuine brake fluid from Škoda Auto a.s. The specification
for the brake fluid is “FMVSS 116 DOT 4”.

Wheels and Tyres241
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
•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 partic ularly applies to vehicles which are equipped with low-
profile tyres or high-speed tyres (code index H or V 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 in flated to 20 kPa (0.2 bar) more than is
the case for summer tyres ⇒page 237.
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 239,
⇒ . 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 237.
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.
WARNING
You must on no account drive your car at more than the permissible
maximum speed for your winter tyres - risk of an accident resulting from
tyre damage and loss of control over your car.
For the sake of the environment
Fit your summer tyres on again in good ti me since summer tyres offer you better
grip and handling on roads which are free of snow and ice as well as ar tempera-
tures below 7 °C - the braking distance is shorter, there is less tyre noise, tyre wear
is reduced and fuel consumption is reduced.
Note
Please observe the various differing legal requirements regarding tyres.
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of the tyre.
This indicates the direction of rotation of the tyre, and it is essential that the tyres
are fitted on to run in this direction. Only then are the tyres able to provide the
optimal properties in terms of grip, lo w noise, wear-and-tear and aquaplaning.
Should it be necessary to fit on a spare wheel in exceptional cases with a tyre not
dedicated to the running dire ction or in opposite running direction, please adopt a

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 249 or the caps ⇒page 249.
– In the case of light alloy wheels remove the wheel trim cap ⇒page 250.
– First of all slacken the safety wh eel bolt * and afterwards the other
wheel bolts ⇒page 250.
– Jack up the vehicle until the wheel to be changed is clear of the ground
⇒ page 251.
– 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 (crosswise) and last the safety wheel bolt* ⇒page 250.
– 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 237.
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. 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 239 if the vehicle is
subsequently fitted with tyres which are different to those it was fitted with
at the works.

– Release the clutch particularly gent ly when starting off or depress the
accelerator particularly gently if yo ur vehicle is fitted with an auto-
matic gearbox.
Driver of the towed vehicle
– Switch the ignition on so that the steering wheel is not blocked and you can also operate the turn signal lights, the headlight flasher, the
windscreen wipers and wi ndscreen washer system.
– Take the vehicle out of gear or move the selector lever into position N
if your vehicle is fitted with an automatic gearbox.
– Note that the brake servo unit and power steering only operate if the engine is running. You will require si gnificantly greater physical force
to depress the brake pedal and to steer the vehicle if the engine is not
running.
– Ensure that the tow rope is always kept taught.
Tow rope or tow bar
A tow bar is safest way of towing a vehicle and also minimizes any shocks. You can
use a tow rope only if a suitable tow bar is not available.
The tow rope must be elastic to protect the vehicle. Thus one should only use
plastic fibre rope or a rope made out of a similarly elastic material.
Only attach the tow rope to the towing eyes provided for this purpose ⇒page 254
and ⇒page 255.
Driving style
Towing another vehicle requires a certain amount of practice. Both drivers should
be familiar with the particular points about towing a vehicle. Unskilled drivers
should not attempt to tow in another vehicle or to be towed in.
One should be constantly vigilant not to allow impermissibly high towing forces or
jerky loadings. There is always a risk of excessive stresses and damage resulting at
the points to which you attach the tow ro pe or tow bar when you attempt to tow a
vehicle which is not standing on a paved road.
Caution
If the gearbox of your vehicle no longer contains any oil because of a defect, your
vehicle must only be towed in with the driven wheels raised clear of the ground, or
on a special vehicle transporter or trailer.
Note
•Please comply with any legal requirements particularly regarding the switched
on signal systems, when towing in or tow-starting another vehicle.
•The tow rope must not be twisted as it may in certain circumstances result in the
front towing eye being unscrewed out of your vehicle.
Front towing eye
The towing eye is stored in the box for the vehicle tool kit.
