Taking care of your vehicle and cleaning the vehicle205
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Removing stains
– Remove fresh stains which are water-based (e.g. coffee, tea, juices,
blood etc.) with an absorbent cloth or household paper or use the
cleaner from the care set for a stain which has already dried in.
– Remove fresh stains on a fat base (e.g. butter, mayonnaise, chocolate
etc.) with an absorbent cloth or household cleaning paper or with the
cleaner from the care set if the stain has not yet penetrated into the
surface.
– Use a grease dissolver for grease stains which have dried in .
–Eliminate special stains (e.g. ball-point pens, felt pen, nail varnish,
dispersion paint, shoe cream etc.) with a special stain remover suit-
able for leather.
Leather care
– Treat the leather every six months with the leather care product avail- able from Škoda Service Partners.
– Apply only a small amount of the care product.
– Dry the leather off with a soft cloth
It is best to consult your Škoda Service Partner if you have any questions regarding
cleaning and care of the leather interior.
Caution
•You must on no account treat the leathe r with solvents (e.g. gasoline, turpen-
tine), floor wax, shoe cream or such like.
•Avoid leaving your vehicle for lengthy pe riods in bright sunlight in order to
avoid bleaching the leather. If you leave your vehicle parked in the open for lengthy
periods, protect the leather from the direct rays of the sun by covering it over.
•Sharp-edged objects on items of clothing such as zip fasteners, rivets, sharp-
edged belts may leave permanent scratche s or signs of rubbing on the surface.
Note
•Use a care cream with light blocker and impregnation effect regularly and each
time after cleaning the leather. The cream no urishes the leather, allows it to breathe
and keeps it supple and also provides moisture. It also creates surface protection.
•Clean the leather every 2 to 3 months, remove fresh soiling each time this
occurs.
•Remove fresh stains such as those from ball-point pens, ink, lipstick, shoe
cream etc., as quickly as possible.
•Care also for the leather dye. Refreshen areas which have lost their colour with
a special coloured leather cream as required.
Seat belts
– Keep the seat belts clean!
– Wash seat belts which have become soiled using a mild soapy solu-
tion.
– Inspect the seat belts regularly to ensure they are in good condition.
Belt webbing which has become severely so iled may prevent the inertia reel from
reeling up the belt properly.
WARNING
•The seat belts must not be removed for cleaning.
•Never clean the seat belts chemically as dry cleaning may destroy the
fabric. The seat belts must also not be allowed to come into contact with
corrosive liquids (such as acids etc.).
•Seat belts which have damage to the webbing, the connections, the
inertia reel or the lock should be replaced by a Škoda Service Partner.
•Inertia reel belts must be completely dried before being reeled up.

Fuel
206
Fuel
Petrol
Grades of petrol
There are various grades of petrol. Please read ⇒page 255, “Technical Data” in
order to know which grade of petrol your vehicle requires. You will also find the
same information affixed to the inside of the fuel filler flap of your vehicle
⇒ page 207, fig. 193 .
A distinction is made betwee n unleaded and leaded petrol . All Škoda vehicles with
petrol engines are equipped with a cataly tic converter and must therefore be only
driven with unleaded petrol . Unleaded petrol complies with the standard
DINEN228 .
The individual grades of petr ol are distinguished by their octane number (RON).
Please adopt the following procedure if th e grade of petrol which you normally use
is not be available in exceptional circumstances:
•Engines which need unleaded premium petrol 95 RON can also be run on
unleaded regular petrol 91 RON. This does, however, result in a slight loss in
performance.
•Engines which need unleaded premium plus petrol 98 RON can also be run
on unleaded regular petrol 95 RON. This do es, however, result in a slight loss in
performance. You can in exceptional circumstances also use unleaded regular
petrol of 91 RON in the event that neither unleaded premium petrol of 98 RON nor
95 RON is available. Refuel as soon as possible with unleaded premium plus of 98
RON or unleaded premium petrol of 95 RON.
If, in an emergency, the only fuel availa ble is one which has a lower octane number
than that required by the engine then only drive at medium engine speeds and
lower engine loadings.
You can make unlimited use of fuel which has a higher octane number than that
required by the engine. There will, however, be no advantages gained by this in
terms of engine performa nce and fuel consumption! The handling, performance and life of your
engine are determined to a significant
extent by the quality of the fuel. Do not use any petrol additives. Use a fuel
complying with the standard.
You can find further information on refuelling ⇒page 207, “Refuelling”.
Caution
•Filling the tank even only once with le aded petrol will result in the catalytic
converter being destroyed.
•Operating the engine with petrol of a low octane number can result in engine
damage at high revolutions or severe engine loading.
Diesel
Diesel fuel
Your vehicle can be operated with diesel fuel, which complies with the standard
DIN EN 590.
Fuel additives
You must not use fuel additives, so-ca lled “flow improvers” (petrol and similar
products) in diesel fuel.
If the quality of the diesel fuel is p oor, it is then necessary to drain the fuel filter
more often than stated in the Service schedule.
You can find information on refuelling ⇒page 207, “Refuelling”.
Caution
•Use a fuel which complies with the standard DINEN590. Filling the tank even
only once, which does not comply with th e standard, can result in damage to the
fuel system.
•Water which has collected in the fuel filter can result in engine problems.

Fuel207
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
•Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must not
be refuelled and driven. Using this fuel (RME) can lead to damage to the engine or
the fuel system.
Operation in winter
Winter-grade diesel fuel
A different grade of diesel fuel is available at filling stations in winter than during the
summer. Using “summer-grade diesel fuel” at temperatures below 0°C can result in
operational problems because the diesel be comes viscous as a result of paraffin
separation.
It is therefore the case that DIN EN 590 prescribes diesel fuel class for certain
periods of the year which can also be pu rchased at the corresponding time during
the year. “Winter-grade diesel fuel” will still operate properly even at a temperature
of -20°C.
It is often the case in countries with diff erent climatic conditions that diesel fuels
available have a different temperature characteristic. Škoda Service Partners and
filling stations in the count ry concerned will be able to provide you with informa-
tion regarding the diesel fuels available.
Prewarming fuel
The vehicle is fitted with a fuel filter prewarming system. This secures operation of
a vehicle using diesel fuel down to an environmental temperature of -25°C.
Caution
It is not permitted to add the various fuel additives on the market, including petrol,
to diesel fuel in order to improve its flow properties.
Refuelling
The filler flap is automatically unl ocked or locked* with the central
locking.
Opening the fuel filler cap
– Press onto the left side of the fuel filler flap ⇒fig. 192 .
– The fuel filler cap on the fuel filler tube must be unlocked to the left using the vehicle key (only valid for vehicles which do not have auto-
matic unlocking of the fuel filler flap).

Engine oil
Engine oil specifications
The grade of engine oil should be selected in accordance with
precise specifications.
The engine of your vehicle has been fact ory-filled with a high-grade oil which you
can use throughout the year - exce pt in extreme climatic regions.
You can mix various oils together with each other when refilling with oil. This does
not, however, apply for models with flexible service intervals (QG1).
Engine oils are, of course, undergoing co ntinuous further development. Thus the
information stated in this Owner's Manual is only correct at the time of publication.
Škoda Service Partners are informed by Škoda Auto a.s. about current changes. This
why you should always have engine oil changed by your Škoda Service Partner.
The specifications (VW standards) stated in the following must be indicated sepa-
rately or together with other specifications on the bottle.
Engine oil specifications for vehicles with fixed service intervals (QG0, QG2) Engine oil specifications for models with flexible service intervals (QG1)
Caution
Only the above-mentioned oils may be used on vehicles with flexible service inter-
vals (QG1). We recommend always refilling with oil of the same specification since
this will maintain the properties of the oi
l. 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 oi ls - risk of engine damage!
Note
•Before a long drive we recommend th at you purchase and carry with you
engine oil which complies with the specif ication for your vehicle. Consequently,
you will always have the correct engine oil for refilling.
•We recommend using a preservative fr om the Škoda original accessories
offered by your Škoda dealer.
•For further information - see Service shedule.

Inspecting and Replenishing
214
– Inspect the oil level ⇒page 213.
– 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 210, “Working in the engine
compartment” before working in the engine compartment.
For the sake of the environment
The oil level must on no account be above the range ⇒page 213. Oil will other-
wise be drawn in through the crankcase ventilation and may pass through the
exhaust system to atmosphere. The oil ma y 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 12.
WARNING
•Only carry out the engine oil change, if you have the required profes-
sional knowledge!
•Read and observe the warning notes ⇒page 210, “Working in the engine
compartment” before working in the engine compartment.
•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 children and
unauthorized persons until you dispose of it properly.
Caution
You must not pour any additives into th e engine oil - risk of engine damage!
Damage, which results from such produc t, 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 prop erly disposing of old oil, the material,
equipment and the knowledge required fo r such work, we recommend that you
have the oil and oil filter change carr ied out by your Škoda Service Partner.
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 an y maintenance under normal operating
conditions. The coolant consis ts of water with a concentration of coolant additive
of 40 %. This mixture not only provides antifreeze protection 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 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.

Inspecting and Replenishing215
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
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 filled at the works with coolant (purple in colour), which
complies with the specification TL-VW 774 F.
We recommend that you use the same coolant additive - G12 PLUS (purple in
colour).
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 ⇒ in “Working in the engine compartment” on
page 210.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 199 .
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 28. We neve rtheless 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 expan-
sion bottle which is completely free of leak s if the coolant boils as a result of over-
heating and is forced out of the cooling system.
WARNING
Read and observe the warning notes ⇒page 210, “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 over-
heating itself cannot be determined and removed, since there may be grave
damage to the engine.

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 ⇒ in “Working in the engine compartment” on
page 210.
– Inspect the brake fluid level in the reservoir ⇒fig. 200 . 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. A situ-
ation where the brake fluid level is too low is indicated by the warning light

lighting up in the instrument cluster ⇒page 32. In this case stop the car immedi-
ately and do not drive any further! Co ntact a Škoda Dealer to obtain profes-
sional assistance.
WARNING
•Read and observe the warning notes ⇒page 210, “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”.
We recommend that you have the brake fluid replaced by a Škoda Service Partner
as part of an Inspection Service.
WARNING
•Using old brake fluid can result in seve re stress on the brakes because of
the formation of vapour bubbles in th e brake system. This greatly impairs
the braking efficiency and thus al so the safety of your vehicle.
•Brake fluid is toxic! It must therefor e be kept safely in closed original
containers and well away from children and unauthorized persons.
Caution
Brake fluid damages the paintwork of the vehicle.

Battery
Working on the battery
The battery is located in the engine compartment below a plastic cover*.
– Press the interlock on the side of the battery cover ⇒fig. 201 , fold the
battery cover out and pull it out.
– The installation of the battery co ver takes place in the reverse order.
Removal and installation of the battery is not recommended since it can, under
certain circumstances, le ad to major damage. Contact a specialist garage.
There is a risk of injuries, scalding, acci dents and burns when carrying out any work
on the battery and on the electrical system. For this reason, it is essential to comply
with the warning instructions ⇒ stated below and with the general applicable
rules of safety.
WARNING
•The battery acid is strongly corros ive and must, therefore, be handled
with the greatest of care. Always we ar protective gloves, eye and skin
protection when handling batteries. Corrosive fumes in the air irritate the
air passages and lead to conjunctivitis and inflammation of the air passages
in the lungs. Battery acid corrodes de ntal enamel and creates deep wounds
after contact with the skin which take a long time to heal. Repeated contact
with diluted acids causes skin diseases (inflammations, ulcers, slin cracks).
Acids coming into contact with water are diluted accompanied by significant
development of heat.
•Do not tilt the battery otherwise battery electrolyte may flow out of the
battery vent openings. Protect the eyes with safety glasses or a shield! There
is the danger of suffering blindness! If any battery electrolyte gets into your
eye, rinse out your eye immediately with clear water for several minutes.
Contact a doctor without delay.
•Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. Contact a
doctor immediately if you swallow battery electrolyte.
•Keep batteries out of the reach of children.
•Hydrogen is released when you char ge a battery and a highly explosive
gas mixture is produced. An explosion can be caused through sparkling over
during unclamping or loosening of the cable plug while the ignition is on.
•Bridging of the poles will create a short circuit (e.g. through metal
objects, cables). Possible consequences of a short circuit: Melting of lead
struts, explosion and burning of the battery, jets of acid spurting out.
•It is prohibited to work with a naked flame and light, to smoke or to carry
out any activities which produce sparks. Avoid creating sparks when
working with cables and electrical device s. Strong sparking represents a risk
of injury.
•Before carrying out any work on the electrical system, switch off the
engine, the ignition as well as all electrical components and disconnect the
negative cable (-) on the battery. If you wish to replace a bulb it is sufficient
to switch off the appropriate light.
