Engine oil specifications for models with flexible service intervals
(QG1)
Caution
Only the above-mentioned oils may be used on vehicles with flexible
service intervals (QG1). We recommend always refilling with oil of the
same specification since this will maintain the properties of the oil. In
exceptional cases, you must top up only once engine oil complying with
Specification VW 502 00 (only for petrol engines) or Specification VW 505
01 (only for diesel engines) to maximum 0.5 litres. You must not use other
engine oils - risk of engine damage!
Note
•Before a long drive we recommend that you purchase and carry with
you engine oil which complies with the specification for your vehicle.
Consequently, you will always have the correct engine oil for refilling.
•We recommend using a preservative from the Škoda original accesso-
ries offered by your Škoda dealer.
•For further information - see Service shedule.
Inspecting the 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 compart-
ment” on page 248.
– Wait a few minutes and pull out the oil dipstick.
– Wipe off the dipstick with a clean cloth and insert it again fully.
– Then withdraw the dipstick again 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 252. It is sufficient, once this
is done, to keep the oil level is within range .
It is normal for the engine to consume oil. The oil consumption may be as
much as 0.5 l/1 000 km depending on your style of driving and the condi-
tions under which you operate your vehicle. The oil consumption 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 if the engine
has been operating at high loads, for example during a lengthy motorway
trip during the summer months, towing a trailer or negotiating a high
mountain pass, but not above this .
The warning light in the instrument cluster* will indicate ⇒page 38,
“Engine oil level* ” 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 extend 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 prevailing to top up with oil. Switch of the engine
and contact and obtain professional assistance from a specialist
garage.
Replenishing engine oil
– Inspecting the engine oil level ⇒page 251.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 250, “Engine oil specifications”.
– Inspect the oil level ⇒page 251.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING
•Avoid dripping oil onto hot parts of the engine when topping up
will oil - a risk of fire!
•Read and observe the warning notes ⇒ page 248, “Working in
the engine compartment” before working in the engine compart-
ment.
For the sake of the environment
The oil level must on no account be above the range ⇒page 251. Oil
will otherwise be drawn in through the crankcase ventilation and may pass
through the exhaust system to atmosphere. The oil may combust in the
catalytic converter and damage it.

Changing engine oil
The engine oil must be changed at the intervals stated in the Service
schedule or according to the service interval indicator ⇒page 16.
WARNING
•Only carry out the engine oil change, if you have the required
professional knowledge!
•Read and observe the warning notes ⇒page 248, “Working in
the engine compartment” before working in the engine compart-
ment.
•Let the engine cool down - risk of burning from hot oil.
•Wear an eye protection - risk of caustic burns due to oil
splashes.
•Oil is toxic! Store old oil in a safe place out of the reach of chil-
dren and unauthorized persons until you dispose of it properly.
Caution
You must not pour any additives into the engine oil - risk of engine
damage! Damage, which results from such product, are excluded from the
warranty.
For the sake of the environment
•You must on no account pour oil into the ground or into the sewage
system.
•In view of the problems involved in properly disposing of old oil, the
material, equipment and the knowledge required for such work, we recom-
mend that you have the oil and oil filter change carried out by your Škoda
dealer.
Note
After your skin has come in contact with the oil, you must thoroughly wash
your skin.
Cooling system
Coolant
The job of the coolant is to cool the engine.
The cooling system does not require any maintenance under normal oper-
ating conditions. The coolant consists of water with a concentration of
coolant additive of 40 %. This mixture not only provides antifreeze protec-
tion down to -25°C but 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 concentration of antifreeze agent in the
coolant by adding water, also not during the summer months or in coun-
tries 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 iIf a higher
concentration of antifreeze is necessary for climatic reasons but only up
to 60% (antifreeze protection down to approx. -40°C). The antifreeze
protection tails off above that concentration.
Vehicles exported to countries with a cold climate (e.g. Sweden, Norway,
Finland) are already factory-filled with a coolant which offers antifreeze
protection down to about -35°C. In these countries the concentration of
coolant additive should be at least 50 %.

Inspecting and Replenishing255
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
recommend inspecting 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.
Losses can only occur through the pressure relief in the cap of the coolant
expansion bottle which is completely free of leaks if the coolant boils as a
result of overheating and is forced out of the cooling system.
WARNING
Read and observe the warning notes ⇒page 248, “Working in the
engine compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as soon as possible if the source
of overheating itself cannot be determined and removed, since there may
be grave damage to the engine.
Replenishing the coolant
– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir ⇒fig. 194 and unscrew the cap carefully by turning it to the
left ⇒ . – Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with
one specific specification
⇒page 253, “Coolant”. Do not use an alternative
additive if the coolant additive G12 PLUS is not available in exceptional
cases. Just top up the system with water and as soon as possible arrange
adjustment to correct the mixing ratio of water and coolant additive again
by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill up over the “MAX” marking! Excess coolant which is heated up
is forced out of the cooling system through the pressure relief valve in the
cap of the coolant compensation bottle.
Wait until the engine has cooled down for a system which has suffered a
major loss of coolant before pouring in coolant. This is necessary to avoid
engine damage.
WARNING
•The cooling system is pressurized! Do not open the cap of the
coolant expansion bottle if the engine is still hot - risk of scalding!
•The coolant additive and thus all of the coolant is harmful to
your health. Avoid contact with the coolant. Coolant vapours are
also harmful to the he alth. It is important, therefore, to always
safely store any coolant additive in its original container out of the
reach of children - risk of poisoning!
•If any splashes of coolant get into your eyes, rinse out your eyes
immediately with clear water and contact a doctor as soon as
possible.
•You should also consult a doctor without delay if you have inad-
vertently swallowed coolant.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
A slight drop in the fluid level results when driving due to normal wear-and-
tear and automatic adjustment of the brake 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. A situation where the brake fluid level is too low is indi-
cated by the warning light
 lighting up in the instrument cluster
⇒ page 40. In this case stop the car immediately and do not drive any
further! Contact a Škoda Dealer to obtain professional assistance.
WARNING
•Read and observe the warning notes ⇒page 248, “Working in
the engine compartment” before working in the engine compart-
ment.
•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. The 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. The specifi-
cation for the brake fluid is “FMVSS 116 DOT 4”.
We recommend that you have the brake fluid replaced by a Škoda dealer
as part of an Inspection Service.
WARNING
•Using old brake fluid can result in severe stress on the brakes
because of the formation of vapour bubbles in the brake system.
This greatly impairs the braking efficiency and thus also the safety
of your vehicle.
•Brake fluid is toxic! It must therefore be kept safely in closed
original containers and well away from children and unauthorized
persons.
Caution
Brake fluid damages the paintwork of the vehicle.
For the sake of the environment
In view of the problems involved with proper disposal of brake fluid, the
special tools and the professional knowledge required, you should have
the brake fluid replaced by a Škoda dealer.

Wheels and Tyres
Wheels
General comments
•New tyres do not offer optimal grip at first and should therefore be run
in for about 500 km at a moderate speed and an appropriately cautious
style of driving. You will also profit from longer tyre life.
•The tread depth of new tyres may differ because of design features
and the configuration of the tread (depending on the type of tyre and the
manufacturer).
•Drive over curbs on the side of the road and other such obstacles
slowly and, where possible, at a right angles in order to avoid damage to
tyres and wheel trims.
•Inspect your tyres from time to time for damage (punctures, cuts, splits
and bulges). Remove foreign bodies from the tyre profile.
•Damage to tyres and wheels is frequently not visible. Unusual vibra-
tions or pulling of the vehicle to one side could be a sign of tyre damage.
Please reduce your speed immediately and stop if you suspect that
a wheel is damaged. Inspect the tyres for signs of damage (bulges,
splits, etc.) If no visible damage is present, please drive at an appropri-
ately slow speed and carefully to the nearest specialist garage in order to
have your vehicle inspected.
•Also protect your tyres from contact with oil, grease and fuel.
•Immediately replace any dust caps of the valves which have got lost.
•Mark wheels before removing them so that their previous direction of
running can be maintained when mounted them again.
•Always store wheels or tyres which been removed in a cool, dry and,
where possible, dark place. Tyres which are not fixed to a wheel trim
should be stored upright. 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, low noise, wear-
and-tear and aquaplaning.
Further information concerning the use of unidirectional tyres
⇒page 268.
WARNING
•New tyres during the first 500 km do not offer optimal grip and
should therefore be run approp riately - risk of accident!
•Never drive with damaged tyres - risk of accident!
Note
Please observe the various differing legal requirements regarding tyres.

risk of accident! Approval and li
cencing 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 permis-
sible for your tyres - risk of an accident resulting from tyre damage
and loss of control 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. Tyres 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 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.
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.

Accessories and replacement parts
Škoda vehicles have been built according to the latest discoveries in
safety engineering. Thus one should not change the condition in which the
vehicle was delivered from the manufacturer without some thought.
The following guidelines should be observed when a vehicle is to be retro-
fitted with accessories, have technical changes made to it or a part has to
be replaced at some time in the future:
•Advise should always be obtained from a Škoda dealer before buying
any accessories and before making any technical changes ⇒.
•This is particularly the case when accessories are bought in a foreign
country.
•Škoda Genuine Accessories which have been released for use and
Skoda original parts can be obtained from Škoda dealers. They will install
them professionally and correctly.
•All Škoda original accessory which is listed in the catalogue such as
tilting roofs, spoilers, wheels etc. must have an official stamp of approval.
•Radios, aerials and other electrical accessories should only be
installed by an authorised workshop.
•The guidelines issued by Škoda Auto must be observed when making
technical changes.
•This is to ensure that no technical damage occurs to the vehicle, that
travelling and operating safety are maintained and that the chnages are
permissible. Škoda dealers undertake this work professionally or refer it
to an specialist company in special cases.
Any damage which is done caused by technical changes made
without consulting a Skoda dealer is excluded from the guarantee.
WARNING
•We advise you, in your own interest, to only use Škoda Genuine
Accessories and Škoda original parts which have been expressly
approved for use on your Škoda. Reliability, safety and suitabiliity
have been established for these Škoda original parts.
•We cannot guarantee suitability of installation into your vehicle
of other products despite keeping a constant eye on market devel-
opments (also not in the case where there is an attestation or
permission can be produced).
Technical changes
Interference on the electronic components and their software can lead to
operational faults. This interference can also impair not directly affected
systems because of the networking of the electronic components. This
means that the operating safety of your vehicle can be considerably jeop-
ardized, a greater wear of vehicle parts can occur and finally the vehicle
registration documents expire.
We trust that you will understand that your Škoda dealer cannot be liable
for damage resulting from unprofessional work.
We therefore recommend that you have all work carried out with Škoda
original parts at your authorised Škoda dealer.
