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. We recommend having this oil change und ertaken by a Škoda Service Partner.
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 that 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.

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 174.
– 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. It is sufficient, once this is done, to keep the
oil level is within range .
It is normal for the engine to consume oi l. The oil consumption may be as much as 0.5 l/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 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 25 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.
WARNING
Read and observe the warning notes ⇒page 174, “Working in the engine compartment” before working in the engine compartment.
Caution
•Always check the oil level on vehicles with engine 1.2 l/51 kW when the engine is warm. Otherwise the measuring result is incorrect und oil could be incorrectly replenished - risk of engine damage!
•The oil level must on no account ex tend beyond the range . Danger of damaging the cata lytic 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 the engine off and obtain profes- sional assistance from a specialist garage, otherwise it could lead to severe engine damage.

Replenishing engine oil
– Inspect the oil level ⇒page 177.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 176,
“Engine oil specifications”.
– Inspect the oil level ⇒page 177.
– 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 174, “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 177. Oil will other- wise be drawn in through the crankcas e 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 11.
WARNING
•Only carry out the engine oil change, if you have the required profes- sional knowledge!
•Read and observe the warning notes ⇒page 174, “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 properly 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 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 filled at the works with coolant (purple in colour), which complies with the specification TL-VW 774 F.
We recommend that you use the antifreeze agent - G12 PLUS (purple in colour).
We recommend that you contact your Škod a Service Partner if you have any ques- tions 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 174.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 159.
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 24. We nevertheless 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 174, “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.
Replenishing the coolant
– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir
⇒ page 179, fig. 159 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 178, “Coolant”. Do not use an alternative additive if the coolant additive G12 PLUS is not availa ble 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 health. 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 yo ur eyes, rinse out your eyes immedi- ately with clear water and contact a doctor as soon as possible.
•You should also consult a doctor without delay if you have inadvertently swallowed coolant.
Caution
Do not continue your journey if for some reason it is not possible under the conditions prevailing to top up with coolant. Switch the engine off and obtain professional assistance from a specialist garage, otherwise it could lead to severe engine damage.
For the sake of the environment
Do not re-use coolant if it is necessary to drain the coolant in the system. It should be collected and disposed of in comp liance with environmental protection regulations.

Radiator fan
The radiator fan may switch on suddenly.
The radiator fan is driven by an electric motor and controlled by a thermostat 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 working 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 ⇒ in “Working in the engine compartment” on
page 174.
– Inspect the brake fluid level in the reservoir ⇒fig. 160. 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 28. In this case stop the car immedi- ately and do not drive any further! Cont act a Škoda Dealer to obtain profes- sional assistance.
WARNING
•Read and observe the warning notes ⇒page 174, “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.

Inspecting and Replenishing182
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 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 aw ay 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, we recommend you have the brake fluid replaced by a Škoda Service Partner.
Battery
Working on the battery
The battery is located in the engine compartment below a plastic box.
– Unlock the interlock on the positive terminal side of the battery
⇒ fig. 161.
– Open the cover in direction of arrow.
– The installation of the battery cover on the positive terminal side takes
place in the reverse order.
Removal and installation of the battery is not recommended since it can, under certain circumstances, lead to major damage to the battery and fuse boxes. 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 corrosive 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 dental 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. Prot ect 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.
•Never charge a frozen or thawed battery - risk of explosion and caustic burns! Replace a frozen battery.
•Never use a battery which is damaged - risk of explosion! Immediately replace a damaged battery.
Caution
•You must only disconnect the battery if the ignition is switched off, otherwise the electrical system (electronic components) of the vehicle may be damaged. When disconnecting the battery from the el ectrical system of the vehicle, first disconnect the negative terminal (-) of th e battery. Then disconnect the positive terminal (+).
•When reconnecting the battery, first conne ct the positive terminal (+) and only then the negative terminal (-) of the batt ery. You must on no account connect the cables wrongly - risk of a cable fire.
•Ensure that battery acid does not come into contact with the vehicle body otherwise damage could occur to the paintwork.
•Do not place the battery in direct daylight in order to protect the battery housing from the effects of ultra-violet light.
For the sake of the environment
A removed battery is a special type of waste which is harmful to the environment - we recommend that you contact your Škod a Service Partner regarding disposing of the battery.
Note
•Please also refer to the guidelines ⇒page 185, “Disconnecting and recon- necting the battery”, also after connecting the battery.
