GENERAL MAINTENANCE
Loss of coolantA loss of coolant is first and foremost an
indication of a leak. In this case, the cool-
ing system should be inspected by a Škoda
Dealer. It is not sufficient merely to top up
the coolant.
If there is no leak in the system, losses may
also occur if the coolant boils as a result of
overheating and is forced out of the cool-
ing system.
If it is not possible to find and rectify the
cause of overheating, contact a Škoda
Dealer as soon as possible - otherwise
major engine damage may result.Topping up coolantFirst of all, switch off the engine and allow
it to cool down. Then, place a rag around
the cap of the expansion reservoir and
carefully unscrew the cap.Warning
Do not open the cap of the expansion
reservoir when the engine is hot -
risk of scalding. The cooling system
is pressurized!
Checking coolant levelThe coolant reservoir is located in the right
of the engine compartment.
The coolant level can be correctly checked
only when the engine is not running.
When the engine is cold, the coolant in the
expansion reservoir must be in the area of
the „ MIN“ mark and the crosshatched area.
When the engine is warm, the coolant level
may be slightly above the crosshatched
area. If, in exceptional cases, it is only possible
to top up the system with water, the correct
mixture concentration should be restored
without delay by using the specified cool-
ant additive.
If there is a major loss of coolant, do not
pour in coolant until the engine has cooled
down to avoid any engine damage.
Do not top up beyond the crosshatched
area!
Excess coolant is forced out of the cooling
system by the pressure relief valve in the
cap of the expansion reservoir when the
coolant heats up.
Screw the reservoir cap tight!
If the event that you do not have enough
coolant,
do not drive any further. Switch
off the engine and contact a Škoda Dealer
for professional assistance, otherwise there
is a risk of serious engine damage.

144GENERAL MAINTENANCE
Drained coolant should not nor-mally be re-used but should be dis-
posed of by complying with environmen- tal protection regulations.
Radiator fanThe radiator fan is driven by an electric mo-
tor and controlled by a thermostatic switch
in line with the coolant temperature.
Warning
After the engine has been switched
off, the fan may continue running for
a while - even if the ignition is swit-
ched off. It may also start to run again
suddenly after a short time if
- the coolant temperature increases due to heat build-up
- when the engine is hot and the en- gine compartment is heated addi-
tionally by strong sunlight.
Special care should therefore be
taken when working in the engine
compartment.
Brake fluidThe brake fluid reservoir is located in the
left of the engine compartment.Checking fluid levelThe fluid level should always be between
the „MAX“ and „MIN“ markings on the re-
servoir.
A slight drop in the fluid level occurs when
driving as a result of wear and tear and au-
tomatic slack adjustment of the brake pads.
This is perfectly normal.
Warning
The coolant additive and the coolant
are poisonous! Do not breathe in
coolant vapours, do not swallow
coolant, avoid contact with eyes and
skin.
If coolant splashes into your eye,
rinse out immediately with clear wa-
ter and contact a doctor.
If coolant is swallowed, you should
likewise contact a doctor. The cool-
ant additive should therefore be
safely stored in the original contain-
ers out of the reach of children.
If the coolant has to be drained out
of the cooling system of the car at
any time, it should be collected,
marked and likewise stored in a safe
place.

145
GENERAL MAINTENANCE
If the fluid level drops significantly within a
short time, however, or if it drops below the
„MIN“ marking, there may be a leak in the
brake system. Insufficient brake fluid level
in the reservoir is indicated by the brake
warning light coming on, see also page 61.
In such a case, contact a Škoda Dealer
without delay and have the brake sys-
tem inspected.
Warning
Read and observe the warning notes
before working in the engine com-
partment - see page 137.
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 fluidBrake fluid is hygroscopic and conse-
quently absorbs moisture from the sur-
rounding air over the course of time. An
excessive content of water in the brake fluid
can also in the long term be a cause of
corrosion in the brake system. In addition,
the boiling point of the brake fluid is con-
siderably reduced. For this reason, the
brake fluid must be renewed every two
years.
Warning
When the brake fluid becomes too
old, vapour bubbles may form in the
brake system when the brakes are
used hard. The efficiency of the
brakes and thus the vehicle safety is
then seriously affected.
Use only fresh brake fluid conforming with
Specification FMVSS 116 DOT 4, which is
approved by the factory. Warning
Brake fluid is poisonous!
It must therefore only be stored in the
closed original container and, in par-
ticular, out of the reach of children.
Please also note that brake fluid attacks the
paintwork of the car.
Because of the disposal problem, the special tools and specialist
knowledge required, it is best to have the brake fluid change carried out by aŠkoda Dealer.
It is recommended to have the brake fluid
change carried out as part of an Inspec-
tion Service.

146GENERAL MAINTENANCEBatteryThe battery is located in the engine com-
partment.
If the vehicle has not been driven for more
than 4 weeks, the battery will discharge be-
cause some electrical components (e.g.
control units) also use current in standstill.
In order to avoid the battery discharging dis-
connect the negative cable (-) of the bat-
tery or continuously recharge the battery.
For jump-starting car with another battery,
see the section „Do-It-Yourself“.Warning
Pay attention to the following warn-
ing instructions and safety regula-
tions when carrying out work on the
battery.
Access to battery
Pull out the catch on the side of the bat-
tery cover (see arrow) slightly. Lift the bat-
tery cover up and out - see arrow A.
Warning
Pay attention to the following warn-
ing instructions and safety regula-
tions when carrying out work on the
battery.
Removing battery
Pull the cable cover 1 up and out in di-
rection of arrow.

Disconnect the battery from the vehicle
electrical system - pay attention to the
Notes on page 148.

Press the catch (arrows B) on the side
of the holder 2 of the fuse carrier. Open the
holder and fuse carrier by raising it (arrow
C ).

Remove the screw 3 from the battery
holder and take out the fuse plate.

Push the battery forward slightly (toward
the headlamp) and then lift it up and out.

148GENERAL MAINTENANCE
Used batteries are harmful to
the environment and should
therefore be disposed of by
contacting your Škoda Dea-
ler.

When disconnecting the battery
from the electrical system, first of all
disconnect the negative cable (-) and
then the positive cable (+).
The battery must not be disconnec-
ted when the ignition is switched on
and the engine is running otherwise
the electrical system (electronic
components) will be damaged.

When re-connecting the battery,
first of all connect the positive cable
(+) and then the negative cable (-).
The connection cables must on no
account be mixed up - risk of fire in
the wiring!

Never use a battery which is dam-
aged - risk of explosion! Immediately
replace a damaged battery.

Never charge a frozen or thawed
battery - risk of explosion and caus-
tic burns. Replace a frozen battery.
Do not expose the battery to direct sun-
light to protect the housing from ultra-
violet rays.
Ensure that the battery acid does not
come into contact with the paintwork
otherwise the paintwork might be dam-
aged.
Checking electrolyte levelIn normal operating conditions the battery
requires practically no maintenance. It is
nevertheless recommended to inspect the
electrolyte level from time to time. It should
always be between the „MIN“ and „MAX“
markings on the front and back of the bat-
tery. If the electrolyte level has dropped
below the „MIN“ marking, top up the rel-
evant battery cells to the „MAX“ marking
with distilled water .
It is recommended to have the electrolyte
level and density inspected and corrected
by a Škoda Dealer.
Battery with charge state indicator
(magic eye)*The magic eye is located on the top of the
battery. This „magic eye“ alters its colour
depending on the charge state and elec-
trolyte level of the battery. The colour indi-
cated serves as a diagnostic aid for Škoda
Dealerships.
Knock gently on the magic eye before
checking the battery.

150GENERAL MAINTENANCEAfter connecting the battery- restore operation of the convenience sys-tem - see page 16
- set the time - see page 50
- if the radio is protected by a code, set the code - see operating instructions of
car radio
The data of the multifunction display are
erased - see page 50.Replacing batteryIf the battery has to be replaced, the new
battery should have the same capacity, volt-
age (12 volts), amperage, design and have
a plug seal. Škoda Dealers have available
a range of suitable batteries.
Because of the disposal problem in- volved with old batteries, it is best
to have the battery replaced by a Škoda Dealer. Batteries contain substancessuch as sulphuric acid and lead andmust on no account be disposed of in
domestic refuse.
Spark plugsThe spark plugs are replaced as part of the
Škoda Inspection Service.

Should it be necessary to replace the
spark plugs between the Inspection Service
intervals, proceed as follows:Spark plugs and ignition system are matched
to the engine and thus contribute to an ex-
haust with low emission levels.Only the spark plugs selected for the par-
ticular engine should be used in order to
avoid operational problems, engine dam-
age and any infringement of legal require-
ments in respect of emission levels or ra-
dio interference from the spark plugs. Par-
ticularly important aspects are the number
of electrodes, the thermal value and radio
interference suppression.

Spark plugs may also be subject to tech-
nical modifications at short notice. It is
therefore recommended to purchase them
only from Škoda Dealers as they are always
informed of the up-to-date situation.
Ribbed belt
The ribbed belt is one of the components
of the car which is subjected to the most
stress. It is therefore necessary to place
particularly high quality requirements in res-
pect of the belts.

When replacing a ribbed belt, it is not
sufficient to use any ribbed belt of whatever
size. For safety reasons, use only the
ribbed belts selected for your car.

Ribbed belts may also be subject to
technical modifications at short notice. It is
therefore recommended to purchase them
only from Škoda Dealers and to also have
the belts changed there as they are always
informed of the up-to-date situation.

GENERAL MAINTENANCE
Windscreen washer system
The windscreen washer reservoir is located
in the right of the engine compartment. It
holds about 3 litres, or about 5.5 litres in
the case of models with a headlight washer
system.
If the vehicle is equipped with headlight
washer system, it is necessary to only
use certain fluids which do not corrode
any polycarbonate connections.
Filling reservoirWhen topping up windscreen washer
fluid, do not remove the sieve from the
reservoir. Impurities might otherwise
affect proper operation of the wind-
screen washer system.
We recommend always adding a wind-
screen cleaner with wax-dissolving proper-
ties to the water (in winter with antifreeze
protection) as clear water is not generally
sufficient to quickly and intensively clean
the windscreen and the headlight lenses.
Refer to the mixing instructions on the wind-
screen cleaner pack.
Note
Should windscreen cleaner with antifreeze
protection not be available in exceptional
cases, it is also possible to add methylated
spirits (the concentration of methylated
spirits must not be higher than 15 %). Note
in this case, however, that the antifreeze
protection of this concentration is only down
to -5 °C at the most.
Even if your vehicle has heated windscreen
washer* nozzles, in winter you should al-
ways add antifreeze protection to the wa-
ter.
On no account use radiator antifreeze pro-
tection or other additives!
Windscreen wiper bladesThe windscreen wiper blades at the front
and rear must be in proper condition if they
are to ensure clear visibility. Wiper blades
must not be dirtied by dust, insect residues
and wax preservative.
To avoid smears, the windscreen wiper
blades should be cleaned regularly with a
windscreen cleaner. If they are very dirty,
e.g. insect residues, the wiper blades can
also be cleaned with a sponge or cloth.
If the wiper blades rub or „smear“, this may
be caused by wax residues on the wind-
screen as a result of washing the car in an
automatic car wash. For this reason, each
time after washing the car in a car wash
with wax treatment, remove the wax from
the lips of the wiper rubbers and from the
windshield and rear window.
In frosty conditions, check that the wiper
blades are not frozen to the glass before
switching the wipers on for the first time.
For safety reasons, the windscreen wiper
blades should be replaced twice a year.
Windscreen wiper blades are available
from Škoda Dealers.

158GENERAL MAINTENANCE
Motoring abroadPlease give consideration to the following
points when driving abroad with your car:

If your car is fitted with a petrol engine
and catalytic converter, it is important that
unleaded petrol is available on your route -
see also page 128. Information regarding
the availability of unleaded petrol can be
obtained from automobile associations.

In certain countries it is also possible that
the Škoda Dealership network is not fully
developed. Certain replacement parts may
therefore not be available or the personnel
of the Škoda Dealer may be able to carry
out repair work only to a limited extent.
ŠKODA AUTO a. s. in the Czech Republic
and the relevant importers will gladly pro-
vide you with the necessary information re-
garding preparing your car technically for
motoring abroad, the servicing required and
repair facilities.
The addresses of the Škoda dealers in
the @! can be found in the brochure
„Škoda dealers in @!“.
For all other countries, you will find a
contact address in the brochure „Trav-
elling assistant“ or in the local „ Work-
shop listing“.
Masking over headlightsAdapt your headlights for using the car in
countries in which the traffic drives on the
left-hand side: If you use your car in coun-
tries in which traffic drives on the left-hand
side of the road, other road users coming
toward you may be dazzled when you use
the headlights of your car which has been
designed for driving on the right-hand side
of the road. In order to eliminate this prob-
lem, you should mask over the left-hand
wedge-shaped areas of the headlight
lenses with an opaque adhesive strip.
The illustrations show how to mask over the
headlights of a car designed for driving on
the right-hand side of the road, when it is
used in a country in which traffic drives on
the left.
Adapting headlights with gas dis-
charge lamps* (applies to left-hand
and right-hand drive models)If you use your car in countries in which traf-
fic drives on the left-hand side of the road,
other road users coming toward you may
be dazzled when you use the headlights of
your car which has been designed for driv-
ing on the right-hand side of the road.
In order to eliminate this problem, the head-
lights must be adapted.
This adaptation is achieved by switching
over the shroud for low beam in the head-
light module.
This measure is carried out by your Škoda
Dealer. He can also provide you with more
detailed information on this matter.
Adapting the headlights with gas discharge
lamps is not a substitute for headlights
which are designed for driving on the right
or on the left, respectively.

GENERAL MAINTENANCE
Mobile phones
and two-way radios
In addition, it is only possible to achieve the
optimal range of such equipment with an
external aerial.
Note
Please pay attention to the operating
instructions of the mobile phone or two-
way radio!
If you wish to use a mobile phone or two-
way radio with a transmission power of
more than 10 watts, please always discuss
this with your Škoda Dealer as he is in-
structed of the technical facilities which
exist for retrofitting mobile phones and two-
way radios.Warning

Please always devote maximum
attention to driving your car!


Never install mobile phone mounts
on the covers of the airbags or in the
deployment area of the airbags other-
wise there is an increased risk of in-
jury if the airbag is deployed in the
event of an accident!
Installation of mobile phones and two-way
radios requires official approval and should
be carried out by an authorized workshop,
e.g. by a Škoda Dealer.
Škoda Auto has approved the operation of
mobile phones and two-way radios for your
car with a professionally installed external
aerial and a maximum transmission power
of 10 watts.
Use of a mobile phone or a two-way ra-
dio can result in operational problems
to the electronic systems of your car in
the following situations:
- no external aerial
- external aerial incorrectly installed
- transmission power in excess of 10 watts.For this reason, you must not use a mo-
bile phone or two-way radio inside the car
if no external aerial is fitted or if it has been
incorrectly installed.Warning
Using a mobile phone or two-way
radio inside the car without a sepa-
rate external aerial may also be harm-
ful to your health as a result of ex-
cessive electromagnetic fields! Škoda cars are designed to reflect the lat-
est state of safety engineering. To ensure
that this is always the case, do not make
any modifications to your car without proper
consideration. If you wish to retrofit acces-
sories to your car, make any technical modi-
fications or have to subsequently replace
parts, please pay attention to the following
points:


Before purchasing accessories and
before making technical modifications, al-
ways ask the advice of a Škoda Dealer.
This is particularly important when purchas-
ing accessories abroad.

162DO-IT-YOURSELF
Tyre repair spray*
The tyre repair spray is precisely for fast
repairs on small tyre defects up to 5 mm.
The spray does not replace a permanent
tyre repair, the repair serves only as an in-
termediate solution until the next service.

The repair can be directly performed on
the vehicle. Carefully read the enclosed in-
structions for direction of use.
On front-wheel drive vehicles, the spray is
located in the well at the front right of the
polypropylene part behind the spare wheel,
and on 4x4 vehicles, in the boot on the left.
Certain models are equipped with a tyre
repair set which includes a compressor and
a repair flask, instructions and accessories.
On front-wheel drive vehicles this set is lo-
cated in the well at the front right of the
polypropylene part behind the spare wheel,
and on 4x4 vehicles, in the boot on the left
next to the first-aid box.

Apply the handbrake before jack-
ing up the car. Never start the engine
when the car is jacked up - risk of
accident.

If it is necessary to carry out work
underneath the vehicle, ensure that
it is supported on suitable stands.
Spare wheelThe spare wheel is stowed in the well below the
floor covering of the luggage compartment and
is secured by a handwheel.

To ensure that the spare wheel is always
ready for use, check the inflation pressure at
regular intervals.
Vehicles with tyres 205/60 R15 and wheel trims
6.5Jx15 have an emergency wheel as a spare
wheel, which has different dimensions and which
is provided with a warning sticker.
Please pay attention to the following instructions,
if you are going to use an emergency wheel:

After fitting on the wheel, the warning sticker
must not be concealed (e.g. by the wheel trim).

Do not drive with this spare wheel at more
than 80 km/h - risk of accident.
Avoid acceleration at full throttle, sharp braking
and fast cornering.

The inflation pressure for this spare wheel is
identical to the inflation pressure of the standard
tyres.

Use this spare wheel only to reach the near-
est service station, as it is not intended for con-
tinuous use.
