Caution
The oil level must on no account extend beyond the range . Danger of
damaging the catalytic converter.
Replenishing engine oil
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres
⇒page 205, “Engine oil specifications”.
– Inspect the oil level ⇒page 206.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
Do not continue your journey if for some reason it is not possible under
the conditions prevailing to top up with oil. Switch of the engine and
obtain professional assistance from a Škoda dealer.
The location of the engine oil filler opening is shown in the illustration of
the engine compartment ⇒page 204.
For the sake of the environment
The oil level must on no account be above the range ⇒page 206,
fig. 156 . Oil will otherwise be drawn in through the crankcase ventilation and may pass through the exhaust system to atmosphere. The oil may
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 17.
Caution
You must not pour any additives into the engine oil - risk of engine
damage!
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 for such work, we recom-
mend that you have the oil and oil filter change carried out by your Škoda
dealer.
WARNING
Avoid dripping oil onto hot parts of the engine when topping up will
oil - a risk of fire!

WARNING
Store old oil in a safe place out of the reach of children and unau-
thorized persons until you dispose of it properly.

Inspecting and Replenishing209
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 203.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 157. 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 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 Škoda
dealer.
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.
One should contact a Skoda dealer as soon 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
⇒page 208, fig. 157 and unscrew the cap carefully by
turning it to the left ⇒.
– Top up the coolant.
– Screw on the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with
certain specifications ⇒page 208, “Coolant”. Do not use an alternative
additive if the coolant additive G12°PLUS 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 additive again
by a Škoda dealer.
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.
Do not continue your journey if for some reason it is not possible
under the conditions prevailing to top up with coolant. Switch off the
engine and obtain professional assistance from a Škoda dealer.
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!

Inspecting and Replenishing
210
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.
The radiator fan
The radiator fan may switch on suddenly.
The radiator fan is driven by an electric motor and controlled by a thermo-
stat according to the coolant temperature.
After the engine is switched off, the radiator fan may continue running for
up to 10 minutes - even if the ignition is also off. It may also switch on
suddenly after a certain time, if
•the coolant temperature has risen because of an accumulation of heat
or
•the warm engine compartment is heated up additionally by strong
sunlight.
Brake fluid
Inspecting the brake fluid level
You can also see the location of the brake fluid reservoir in the
engine compartment from the general view of the engine
compartment ⇒page 204. The brake fluid reservoir on right-
hand steering models is positioned on the other side of the
engine compartment.
– Switch the engine off.
WARNING (continued)
•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 your eyes, rinse out your
eyes immediately 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.
WARNING
You must therefore be aware when working in the engine compart-
ment that the fan may switch on suddenly - risk of injury!

Inspecting and Replenishing211
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
– Open the bonnet ⇒ in “Working in the engine compart-
ment” on page 203.
– Pull off the rubber seal ⇒fig. 158 partially away and lift the
cover slightly.
– Inspect the brake fluid level at the reservoir . The level must be between the “MIN” and “MAX” markings. The markings are
indicated on the side of the reservoir.
A slight drop in the fluid level results when driving due to normal wear-and-
tear and automatic adjustment of the brake 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 situation where the brake fluid level is too low is indi-
cated by the warning light
 lighting up in the instrument cluster
⇒ page 35. You should drive carefully and immediately to the nearest
Škoda Dealer and have the brake system inspected.
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. The 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 Skoda Auto. The specifi-
cation for the brake fluid is “FMVSS 116 DOT 4”.
We recommend that you have the brake fluid replaced by a Škoda Dealer
as part of an Inspection Service.
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 dealer.

WARNING
•Using old brake fluid can result in severe 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 away from children and unauthorized
persons.

The battery
Working on the battery
Particular care is required when carrying out any work on
the battery!
The battery is located in the engine compartment in the plenum
chamber below a cover.
Taking off cover
– Press the cover in direction of arrow ⇒fig. 159 .
There is a risk of injuries, scalding, accidents and burns when carrying out
any work on the battery and on the electrical system. 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 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 accom-
panied 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 immedi-
ately 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 elec-
trolyte.
•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 crea te 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.

Caution
•You must only disconnect the battery if the ignition is switched on,
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 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 envi-
ronment - contact your Škoda dealer regarding disposing of the battery.
Note
Please also refer to the guidelines ⇒page 216, also after connecting the
battery.
Battery with a charge level indicator, the so-called
magic eye
There is a so-called magic eye ⇒fig. 160 located on the top of the battery.
This indicator changes its colour in line with the charge state and electro-
lyte level in the battery. The colour serves as an aid to your Škoda dealer
in diagnosing the condition of the battery.
Remove the cover ⇒page 212, fig. 159 and knock the magic eye care-
fully before carrying out the battery check.
•green colour - the battery is adequately charged.
•dark colour - the battery has to be charged
•colourless or yellow - the electrolyte level is too low, no indication
regarding the charge state is possible. The battery must be replenished
with distilled water.
Batteries, which are more than 5 years old, must be replaced. We recom-
mend you have the electrolyte level inspected and adjusted to the correct
level or the battery replaced if necessary by a Škoda dealer.
WARNING (continued)
•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.
•You must disconnect the negative terminal (-) of the battery
when carrying out work on the electrical system. If you wish to
replace a bulb it is sufficient to switch off the appropriate light.

Caution
If the vehicle has not been driven for more than 4 weeks, the battery will
discharge gradually as a result from electrical components such as the
control units which were not switched off. 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 ⇒page 212, “Working on the
battery”.
Inspecting the electrolyte level
The 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 dealer when outside temper-
atures are high or when driving on long trips. You should also check the
electrolyte level ⇒page 214 each time the battery is charged.
The battery acid level will also be checked as part of the Inspection
Service.
Caution
Do not expose the battery to direct sunlight for lengthy periods in order to
protect it from UV rays.
Operation in winter
The 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 temperatures. A discharged battery may already freeze at temperatures just below
0°C.
We therefore recommend that you have the battery checked by a Škoda
dealer before the start of the winter, and recharged if necessary.
Note
If the vehicle is not going to be driven for a period of some weeks when
there is very severe frost one should remove
⇒page 215 the battery and
store it in a place which is protected from frost. This prevents the battery
from freezing up and thereby being destroyed.
Charging the battery
A properly charged battery is essential for reliably starting
the engine.
– Read the warning notes ⇒ in “Working on the battery” on
page 212 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.

Inspecting and Replenishing215
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
– 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 the 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 manufac-
turer.
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 212. It requires a special charger and appropriate knowledge. We
therefore recommend that you have your battery quick-charged only by
your Škoda dealer.
A discharged battery may already freeze at temperatures just below 0°C.
If a battery is frozen, it is essential that it is first of all thawed out before
being charged ⇒. 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.
Removing and installing the battery
WARNING
Never charge a battery which is frozen - risk of explosion!

Wheels and Tyres221
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-
and-tear on the tyres but will also has an adverse effect on vehicle safety.
Contact your Škoda dealer if you notice any unusual tyre wear.
For the sake of
the environment
Tyres which are insufficiently inflated increase your fuel consumption.
Wear indicators
The 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 indica-
tors are located at 6 to 8 points depending on the make and are evenly
spaced around the circumference of the tyre ⇒fig. 166 . Markings on the
walls of the tyres through the letters “TWI” or triangular symbols identify
the 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
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.
Fig. 166 Tyre tread
with wear indicators
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 de pth should be observed.
•Worn tyres do not provide the necessary adhesion to the road
surface at high speeds on wet roads. One could experience “aqua-
planing” (uncontrolled movements of the vehicle - “swimming” on
a wet road surface).

Wheels and Tyres223
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
The following
speed restrictions apply to tyres.
The date of manufacture is also stated on the tyre wall (possibly only on
the inside of wheel):
DOT ... 30 01...
means, for example, that the tyre was manufactured in the 30th week of
the year 2001.
Any spare wheel which differs from the tyres fitted to the vehicle (e.g.
winter tyres or low-profile tyres) should only be used only for a short time
in the event of a puncture and when adopting an appropriately cautious
style of driving. It should be replaced as quickly as possible by a normal
wheel.
For the sake of the environment
Old tyres must be disposed of in conformity with the appropriate regula-
tions.
Note
It is not normally possible to fit wheels from other models of cars for tech-
nical reasons. This may also apply in certain circumstances to the wheels
of the same type of vehicle.
Wheel bolts
Wheels and wheel bolts are matched to each other in terms of design.
Each time you fit other wheels - e.g. light alloy wheels or wheels with
winter tyres - you must therefore also use the matching wheel bolts of the

WARNING
•Only use those tyres or wheel rims which have been approved
for your model of Škoda Auto vehicle. Failure to observe this
instruction will adversely affect the road safety of your vehicle -
risk of accident! Approval and licencing of your vehicle on public
roads may also become void as a result.
WARNING (continued)
•You must on no account drive at a higher speed than is permis-
sible for your tyres - risk of an accident resulting from tyre damage
and loss of control over your vehicle.
•Tyres which are 6 years old or more should only be fitted in
exceptional cases and when adopting an appropriately cautious
style of driving.
•Never fit tyres which have already been used without having
adequate knowledge of their previous history. Tyres age even if
they have not been used at all or only very little. A spare tyre must
only be used in exceptional cases and only then when adopting an
appropriately cautious style of driving.
•Do not, where possible, replace individual tyres but at least
replace them on both wheels of a given axle at the same time.
Always fit the tyres with the deeper tread depth to the front wheels.
