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.

156GENERAL MAINTENANCE
Knowledge of the tyre inscription and
its meaning makes it easier to choose the
right tyres. Radial tyres have the following
inscription on the tyre wall:
e.g. 175 / 80 R 14 88 T
175 = Tyre width in mm
80 = Height/width ratio in %
R = Tyre design code for Radial
14 = Wheel diameter in inches
88 = Ply rating
T = Speed code
The following speed categories apply to
tyres:
Code letter Q - max. 160 km/h
Code letter R - max. 170 km/h
Code letter S - max. 180 km/h
Code letter T - max. 190 km/h
Code letter H - max. 210 km/h
Code letter V - max. 240 km/h
The tyres may be damaged if you drive
at more than the maximum speed for the
particular tyre.
The date of manufacture is also indicted
on the tyre wall (possibly only on the inside
of the wheel).
DOT 40.04 means that the tyre was manu-
factured in the 40
th calendar week of 2004.
Warning
Tyres which are more than 6 years
old, should only be used in excep-
tional cases and by adopting a cau-
tious style of driving.
If the car is retrofitted with tyres or wheels
other than the factory-fitted type, pay at-
tention to the following points:
Warning

For technical reasons, it is not per-
mitted on any account to use tyres
or wheels on your car which have not
been approved by the manufacturer
for the particular model.


Wheels and wheel bolts are matched
to each other. If different wheels are fit-
ted to the car (e.g. light alloy wheels or
wheels fitted with winter tyres), it is
then necessary to use the matching
wheel bolts of the correct length and
shape of spherical cap. In view of the
fact that the wheels and wheel bolts,
including security bolts, are matched
for all the wheels approved by the
manufacturer (sheet steel, steel and
light alloy wheels), never use wheel
bolts which are not approved by the
manufacturer. These are universal for
all types of approved wheels and are
tightened in the same way as described
in the section DO-IT-YOURSELF.

Using tyres and/or wheels which
have not been approved by the ma-
nufacturer for your model of car can
be detrimental to the safety of the
vehicle. It may also affect official ap-
proval for use of the vehicle on pub-
lic roads!

163
DO-IT-YOURSELF
Changing a wheelWarning

In the case of a flat tyre or punc-
ture, park the vehicle off the road,
switch on the hazard warning lights
and place the warning triangle in po-
sition - note any statutory require-
ments.

All the vehicle occupants should
leave the car and move to a safe area
(e.g. behind safety barrier).


Apply handbrake firmly and engage
a gear. Chock the opposite wheel with
a stone or similar if the car is stand-
ing on a slope.

Never start the engine when the
car is jacked up - risk of accident!

If towing a trailer, unhitch the
trailer from the car before changing
the wheel.

Carry out wheel change on a flat, level
surface, as far as possible.

Remove the car tool kit and spare wheel
from the luggage compartment.

Attach the wire hook (from the car tool
kit) at the edge of the full wheel trim* oppo-
site the air valve. Push the wheel wrench
through the wire hook and pull off the wheel
trim - see illustration.

If light-alloy wheels are fitted, use the
plastic clip supplied to pull off the covers
for the wheel bolts.

Unscrew the safety wheel bolts* - see
page 166.

Fit wheel wrench onto the wheel bolt as
far as the stop and turn to the left. Hold the
wrench as close as possible to its end for
this operation. If the bolts cannot be slack-
ened, you can carefully apply pressure to
the end of the wheel wrench with your foot.
Ensure that you are standing properly and
hold tight on the car. Slacken the wheel
bolts about one turn.

165
DO-IT-YOURSELF

Jack up car until the wheel is just clear
of the ground.

Remove wheel bolts (after slackening)
1),
place them down on a clean surface (cloth,
paper, wheel cap) next to the car jack and
take off wheel.

Fit on spare wheel and attach wheel
bolts
1).

Tighten all the wheel bolts slightly. The
wheel bolts should be clean and turn freely.

On no account grease or oil them!

Lower car and tighten the wheel bolts
diagonally.

Press on the full wheel trim* first at the
valve opening and then apply pressure
around the entire circumference so that the
trim locks in position.
1)In order to accelerate the screwing out and in,
use the handle part of the screwdriver from the
car tool kit, which has on its end a hexagon
socket for the screw head.

Place the wheel removed in the spare
wheel well and secure with the handwheel.
Notes

After changing a wheel, pay attention to
the following points:
- Check the inflation pressure of the spare wheel fitted.
- Have the tightening torque of the wheel bolts checked with a torque wrench as
soon as possible. The tightening torque
for steel and light alloy wheels is 120 Nm.

Have the faulty wheel repaired as quickly
as possible. Warning
In case of incorrect treatment of the
wheel bolts, the wheel can loosen
when the car is moving - risk of acci-
dent!
Wheel bolts must be clean and must
turn easily. However
, they must never
be treated with grease or oil.
If the wheel bolts are tightened to a
too low tightening torque, the trims
can loosen when the car is moving -
risk of accident! A tightening torque,
which is too high, can damage the
bolts and threads and this can result
in permanent deformation of the con-
tact surfaces on the trims.
If it is intended to subsequently fit
wheels or tyres other than the factory-
fitted versions to the car, it is essen-
tial to read the remarks on page 156.

Notes
The fuse assignment differs depending on
the version of your car.
The pliers for removing fuses and replace-
ment fuses are not contained in the car
equipment.
Replacing a bulbThe relevant light should always be swit-
ched off first of all before replacing a bulb.
Do not grasp the glass of the bulb with your
bare fingers (even the minutest spot of dirt
reduces the operational life of the bulb).
Use a clean cloth, napkin or similar.
A bulb should only be replaced by a lamp
of the same design . The designation is
given on the base of the bulb or on the
glass.
Warning
H4 bulbs are pressurized and may
burst when they are replaced. For
this reason, always wear gloves and
eye protection when changing a H4
bulb. Models with Xenon headlamps*
If your car is fitted with xenon head-
lights, have the bulb (low beam, side
light and main beam) replaced by a
Škoda dealer.
We recommend always carrying with you in
the car a box with a set of spare bulbs, which
you received together with your car, or which
is available from your Škoda Dealer
1).
1)The small box of replacement light bulbs are part
of the basic equipping of the vehicle in some
countries
