
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 cl imatic 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 of fers 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 operat ional 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 consequence of this, result in major engine damage.Petrol engines

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.Inspecting the coolant levelThe coolant expansion bottle is located in the engine compartment on the right.
– Switch the engine off.
– Open the bonnet page 196.
– Check the level of coolant in the coolant expansion bottle fig. 164 . The coolant
level when the engine is cold must lie between the (MIN) and (MAX) mark-
ings. The level may also rise slightly above the (MAX) marking when the engine
is warm.
If the coolant level in the reservoir is too lo w, this is indicated by the warning light in
the instrument cluster page 31, “Coolant temperature/coolant level ”. We never-
theless recommend inspecting the coolant leve l 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 197, “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. 164 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 th e system, must comply with one specific
specification page 200. 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 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.

202WARNING

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 ignition 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 working 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 196.
– Inspect the brake fluid level in the reservoir fig. 165 . 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 th e 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 34, “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 197, “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
a Škoda Service Partner.
BatteryWorking on the batteryFig. 166 Engine compartment: Polyester cover of the vehicle battery / plastic cover of the
vehicle batteryThe battery is located in the engine compartment in a polyester cover fig. 166 - left,
or in a plastic cover* fig. 166 - right.
– Open the battery cover in direction of arrow fig. 166 or press the interlock

– The installation of the battery co ver takes place in the reverse order.
The edge of the polyester battery cover fig. 166 - left is inserted between the battery
and the side wall of the battery co ver when working on the battery.
Removal and installation of the battery is not recommended since it can, under certain
circumstances, lead to major dama ge. Contact a specialist garage.
There is a risk of injuries, scalding, accidents and burns when carrying out any work on
the battery and on the electrical system. For th is 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 wear prot ective 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 enam el 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 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 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, 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. Avoid 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 batt ery - 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 ba ttery. 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.

An indicator for the electrolyte level, the so-called magic eye
page 204, fig. 167 , is
located on the top of the battery. The indicato r changes its colour in line with the elec-
trolyte level in the battery.
Air bubbles can influence the colour of the in dicator. For this reason carefully knock on
the indicator before carrying out the check.

Black colour - electrolyte level is correct.

Colourless or light yellow colour - electr olyte level too low, the battery must be
replaced.
Batteries, which are more than 5 years old, must be replaced. We recommend you
have the battery checked or repl aced by a specialist garage.Caution
If the vehicle has not been driven for more than 3 to 4 weeks, the battery will discharge
because certain electrical components consum e electricity (e.g. control units) also in
idle state. You can prevent the discharging of the battery by disconnecting the negative
terminal or charging the battery constantly with a very low charging current. Please
also refer to the notes wh en working on the battery  in “Working on the battery”
on page 203.

Battery with a three-tone indicatorAn indicator for the electrolyte level and the charge state, the so-called magic eye
 page 204, fig. 167 , is located on the top of the ba ttery. The indicator changes its
colour in line with the charge state of and the electrolyte level in the battery.
Air bubbles can influence the colour of the in dicator. For this reason carefully knock on
the indicator before carrying out the check.

Green colour - the battery is adequately charged.

Dark colour - the battery has to be charged.

Colourless or yellow colour - electrolyte level too low, the battery must be
replaced.
Batteries, which are more than 5 years old, must be replaced. We recommend you
have the battery checked or repl aced by a specialist garage.Caution
If the vehicle has not been driven for more th an 3 to 4 weeks, the battery will discharge
because certain electrical co mponents consume electricity (e.g. control units) also in
idle state. You can prevent the discharging of the battery by disconnecting the negative
terminal or charging the battery constantly with a very low charging current. Please
also refer to the notes when working on the battery  in “Working on the battery”
on page 203.


Batteries with three-tone indicator, whic h are mounted as of factory, are marked
with a code which always begins with 1J0, 7N0 or 3B0 . The exact marking can be e.g.
1J0 915 105 AC .

Replacement batteries with three-tone indi cator, which were obtained from Škoda
original parts, are marked with the code 000 915 105 Ax, whereby “x” stands for a vari-
able. The exact marking can be e.g. 000 915 105 AB.
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 Škoda Service Partner when outside temperatures are high or when driving
on long trips. You should also have the electrolyte level page 206 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 Škoda Service
Partner 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 203 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 the charger off and unplug the mains cable from the power socket.
– Only then should you disconnect the terminal clamps of the charger.
– Reconnect the cables to the battery (first of all “positive”, then “negative”).
It is not normally necessary to disconnect th e cables of the 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 203. It requires a special charger an d appropriate knowledge. We therefore
recommend that you have your battery quick-charged only by your Škoda Service
Par tner.
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.

We recommend having the vehicle checked by a Škoda Service Partner to ensure full
functionality of all electrical systems.
Replacing the batteryYou should only replace a battery with a ne
w battery of the same capacity, voltage (12
V), amperage and of the same size. Škoda Service Partners have a range of suitable
batteries available.
We recommend that you only have an old ba ttery disposed of by your Škoda Service
Partner since it does require special disposal.
For the sake of the environment
Batteries contain poisonous substances such as sulphuric acid and lead. They must be
disposed of in accordance with local environmental protection regulations and on no
account as domestic waste.
In view of the problems involved with it s proper disposal, we recommend having
the battery replaced by a specialist garage.
Windshield washer systemThe windshield washer reservoir contains the cleaning fluid for the windscreen or rear
window and for the headlamp cleaning system*. The reservoir is located at the front
right of the engine compartment fig. 168 . The
filling level of the container is about 3 litres and about 5.5 litres on vehicles which
have a headlight washing system.
Clear water is not sufficient to intensively clean the windscreen and headlights. We
therefore recommend using clean washing water together with the screen cleaner
from Škoda genuine accessories (in winter additionally with antifreeze) which is
capable of removing stubborn dirt. Follow the instructions for use on the packaging
when using screen cleaning products.
You should always add antifreeze to the cleaning water in winter even if your vehicle is
fitted with heated wind screen washer nozzles*.
It is also possible in exceptional cases to use methylated spirits when no screen cleaner
with antifreeze is available. The concentration of methylated spirits must not be more
than 15 %. Please note, however, that the anti freeze protection at this concentration is
only adequate down to -5°C.
WARNING
Read and observe the warning notes page 197, “Working in the engine
compartment” before working in the engine compartment.
Caution

On no account should you add radiator an tifreeze or other additives to the wind-
screen washer fluid.

If the vehicle is fitted with a headlight cleaning system, you should only add
cleaning products which do not attack the polycarbonate coating of the headlights to
the windscreen washer fluid. Please contac t your Škoda Service Partner, who will tell
you which cleaning agent you can use.

Wheels and TyresWheelsGeneral information
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 appropri ately cautious style of driving. You will
also profit from longer tyre life.

The tread depth of new tyres may differ be cause of design features and the config-
uration 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 angle 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 vibrations or pulling
of the vehicle to one side coul d be a sign of tyre damage. Please reduce your speed
immediately and stop if you su spect 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
appropriately 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 mark ed 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 proper-
ties in terms of grip, low nois e, wear-and-tear and aquaplaning.
Further information concerning th e use of unidirectional tyres page 212.
WARNING

New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!

Never drive with damaged tyres - risk of accident!Note
Please observe the various differing legal requirements regarding tyres.Ty re l i feThe life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insufficiently or
over-inflated and this will have an adverse effect on the handling of your vehicle.
Correctly inflated tyres are of particular importance when travelling at high speeds. It
is therefore good to check the pressure at least once a month and also before setting
off on a long trip. Please do not forget the spare wheel when checking the tyres.
The tyre inflation pressures for summer tyres are indicated on the inside of the fuel
filler flap fig. 169 . The inflation pressures for winter tyres are 20 kPa (0.2 bar) higher
than those for summer tyres page 212.

Technical Data
The tyre inflation pressure for tyres of the tyre size 205/50 R17, which are intended to
be used with snow chains, is identical to the tyre inflation pressure for tyres of the tyre
size 225/45 R17, see
page 208, fig. 169 .
The tyre pressure should be at the highest pressure specified for your vehicle at all
times.
The tyre inflation pressure of the emergency spare wheel R 18 is 420 kPa (4.2 bar).
Always check the inflation pressure of tyres when cold. Do not reduce the higher pres-
sure of warm tyres. Adapt the inflation pressure of the tyres accordingly if your vehicle
is carrying a significantly higher payload.
Driving style
Fast cornering, sharp acceleration and brak ing (squealing tyres) increase wear-and-
tear on your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences when
driving which may result in an imbalance and which makes themselves felt through
vibration in the steering.
You should have the wheels rebalanced si nce any imbalance increases wear-and-tear
on the steering, the suspension and tyres. A wheel must also be rebalanced when a
new tyre is fitted and each time a tyre is repaired.
Wheel alignment errors
Incorrect wheel alignment at the front and re ar will not only increase wear-and-tear on
the tyres but will also has an adverse effect on vehicle safety. Contact your specialist
garage if you notice any unusual tyre wear.
WARNING

If the inflation pressure is too low, the tyre must perform a greater flexing
work. At higher speeds the tyre will warm up as a result of this. This can result
in tread separation and even a tyre blowout.

Immediately replace the damaged rims or tyres.

Tyres which are 6 years old or more should only be fitted in exceptional
cases and when adopting an approp riately cautious style of driving.
For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.Wear indicatorsThe base of the tread of the original tyres has wear indicators 1.6 mm high, installed at
right angles to the direction of travel. These wear indicators are located at 6 - 8 points
depending on the make and are evenly spaced around the circumference of the tyre
 fig. 170 . Markings on the walls of the tyres through the letters “TWI”, triangular
symbols or other symbols identify th e position of the wear indicators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the wear
indicators, means that your tyres have reached their legally permissible minimum
tread depth.
WARNING

You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn down . The legally permissible minimum tread
depth should be observed.

Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience “aquaplaning” (uncontrolled
movements of the vehicle - “swimming” on a wet road surface).
