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 conditions under which you
operate your vehicle. The oil consumption may be slightly hi gher 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 high load s, for example during a lengthy motorway
trip during the summer months, towing a tr ailer or negotiating a high mountain pass.
The warning light in the instrument cluster* will indicate page 31 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 the engine off and obtain professional
assistance from a specialist garage, otherwise it could lead to severe engine damage.Note
Engine oil specifications page 243, “Technical Data”.Replenishing engine oil– Inspecting the engine oil level page 205.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres page 246, “Engine oil spec-
ifications”.
– Inspect the oil level page 205.
– 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 204, “Working in the engine
compartment” before working in the engine compartment.For the sake of the environment
The oil level must on no acco unt extend beyond the range page 205. Oil will
otherwise be drawn in through the crankc ase ventilation and may pass through the
exhaust system to atmosphere. The oil ma y combust in the catalytic converter and
damage it.Changing engine oilThe engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator page 18, “Service Interval Display”.
WARNING

Only carry out the engine oil change, if you have the required professional
knowledge!

Read and observe the warning notes page 204, “Working in the engine
compartment” before working in the engine compartment.

First of all, let the engine cool down, we ar an eye protection and gloves - risk
of caustic burns due to hot oil.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 prop erly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you have
the oil and oil filter change carried out by an authorised Škoda Service Partner.Note
After your skin has come in contact with th e oil, you must thoroughly wash your skin.Cooling systemCoolant
The job of the coolant is to cool the engine.The cooling system does not require any maintenance under normal operating condi-
tions. The coolant consists 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 mo nths 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 antifreeze prot ection 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%.
Coolant
The cooling system is factor y-filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the same coolan t additive - G13 (purple in colour) - for
topping up the system. Please contact an authorised Škoda Serv
ice Partner if you have any questions
regarding the coolant or if you wish to fill up with a different coolant.
An authorised Škoda Service Partner can also supply you with the correct coolant addi-
tives.
Coolant capacity
Caution

Other coolant additives may cause operational problems which, in particular,
involves significantly reduci ng the anticorrosion effect.

Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequenc e of this, result in major engine damage.Note
On vehicles which are fitted with an indepe ndent auxiliary heating and ventilation, the
volume of the coolant is greater by approx. 1 ltr.Petrol engines

Inspecting the coolant levelThe coolant expansion bottle is located in the engine compartment on the right.
– Switch the engine off.
– Open the bonnet page 203.
– Check the level of coolant in the coolant expansion bottle fig. 165 . When the
engine is cold, the coolant level must lie between the and markings. When
the engine is warm, the level may also lie slightly above the hatched part.
If the coolant level in the reservoir is too lo w, this is indicated by the warning light in
the instrument cluster page 33, “Coolant temperature/ Coolant quantity ”. We
nevertheless recommend inspecting the cool ant 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 204, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as s oon 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. 165 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 207. Do not use an alternative additive if the coolant additive
G13 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 addi-
tive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not top up the fluid above the hatched pa rt! 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 orig-
inal 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 compliance with environmental protection regulations.Radiator fan
The radiator fan may switch on suddenly.The radiator fan is driven by an electric motor and controlled according to the coolant
temperature.
The radiator fan may continue running for up to 10 minutes after the engine has been
switched off - even if the igni tion is also off. It may also switch on suddenly after a
certain time, if
the coolant temperature has risen beca use of an accumulation of heat or

the warm engine compartment is heated up additionally by strong sunlight.
WARNING
You must therefore be aware when workin g in the engine compartment that the
fan may switch on suddenly - risk of injury!
Brake fluidInspecting the brake fluid levelThe 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 203.
– Inspect the brake fluid level in the reservoir fig. 166 . 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 brak e 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 36, “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 204, “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! Obtain professional assistance.
Replacing brake fluidBrake 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.
One may only use new genuine brake fluid from Škoda Auto. The brake fluid must
comply with one of the following standards or specifications:
VW 50114

FMVSS 116 DOT4

DIN ISO 4925 CLASS 4
We recommend that you have the brake fluid replaced by an authorised Škoda
Service Partner 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 br ake system. This greatly impairs the
braking efficiency and thus also the safety of your vehicle.
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
authorised Škoda Service Partners.

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 create s 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 glas ses or a shield! There is
the danger of suffering blindness! If an y battery electrolyte gets into your eye,
rinse out your eye immediately with cl ear 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 swal low battery electrolyte.

Keep batteries out of the reach of children.

Hydrogen is released when you charge a battery and a highly explosive gas
mixture is produced. An explosion can be caused through sparkling over during
unclamping or loosening of the cabl e 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, explo-
sion 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. Avoi d creating sparks when working with
cables and electrical devices. Strong sparking represents a risk of injury.

Before carrying out any work on the el ectrical 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 jump-start the batteries which have a too low electrolyte level - risk
of explosion and caustic burns!

Never use a battery which is damaged - risk of explosion! Immediately
replace a damaged battery.Caution

You must only disconnect the battery if th e ignition is switched off, otherwise the
electrical system (electronic components ) of the vehicle may be damaged. When
disconnecting the battery from the electrical system of the vehicle, first disconnect the
negative terminal (-) of the battery. Then disconnect the positive terminal (+).

When reconnecting the battery, first connect the positive terminal (+) and only
then the negative terminal (-) of the battery. 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 other-
wise 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 wa ste which is harmful to the environment -
contact your specialist garage regarding disposing of the battery.

Inspecting the electrolyte levelThe battery is practically maintenance-free under normal operating conditions. We
do, however, recommend that you have the electrolyte level inspected from time to
time by a specialist garage when outside temperatures are high or when driving on
long trips. You should also have the electrolyte level  page 213 checked each time
the battery is charged.
The electrolyte level of the battery will al so be checked as part of the Inspection
Service.Operation in winterThe battery has to provide greater amounts of electricity during the winter. It also has
only part of the initial power output at low temperatures that it has at normal temper-
atures.
A discharged battery may already freez e at temperatures just below 0°C.
We therefore recommend that you have the battery checked by a specialist garage
before the start of the winter and recharged if necessary.
WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic burns.
Replace a frozen battery.Charging the battery
A properly charged battery is essentia l for reliably starting the engine.– Read the warning notes  in “Working on the battery” on page 210 and .
– Switch the ignition and all electrical components off.
– Only for “quick-charging”: Disconnect both battery cables (first of all “negative”,
then “positive”).
– Carefully attach the terminal clamps of the charger to the battery terminals (red = “positive”, black = “negative”). – You can now plug the mains cable of the
charger into the power socket and switch
on the charger.
– When charging is completed: switch th e charger off and unplug the mains cable
from the power socket.
– Only then should you disconnect th e terminal clamps of the charger.
– Reconnect the cables to the battery (first of all “positive”, then “negative”).
It is not normally necessary to disconnect the cables of th e battery if you recharge the
battery using low amperages (as for example from a mini-charger). Please also refer
to the instructions from the charger manufacturer.
A charging current of 0.1 of the total battery capacity (or lower) is that which should be
used until full charging is achieved.
It is, however, necessary to disconnect both cables before charging the battery with
high amperages, so-called “ quick-charging”.
“Quick-charging” a battery is dangerous  in “Working on the battery” on
page 210. It requires a special charger an d appropriate knowledge. We therefore
recommend that you have your battery quic k-charged only by an authorised Škoda
Service Partner.
A discharged battery may already freeze at temperatures just below 0°C . We
recommend that you no longer use a battery which has thawed out because the casing
of the battery may be cracked through the formation of ice and this would allow
battery electrolyte to flow out.
The vent plugs of the battery should not be opened for charging.
WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic burns.
Replace a frozen battery.
Never charge a battery which has a too lo w electrolyte level - risk of explo-
sion and caustic burns.
