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.

Technical Data
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.

Disconnecting and reconnecting the batteryOn disconnecting and reconnecting the batt ery the following functions are initially
deactivated or are no longer able to operate fault-free.
We recommend having the vehicle checked by a specialist garage to ensure full func-
tionality 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. The auth orised Škoda Service Partners have a range
of suitable batteries available.
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 its 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. 169 .
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.
