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.

Fit the car jack onto the car. Recesses
are provided on the lower sill (at the front
and rear). Below this is the point at which
the car jack should be positioned - see ar-
rows in the illustration.

Position the car jack so that its claw fits
around the web of the lower sill A and the
moving base plate of the car jack B is posi-
tioned flat on the ground.
Warning

Always raise the vehicle with the
doors closed - risk of injury.

Take suitable measures to prevent
the base of the lifting jack from slip-
ping off - risk of injury!

Place the lifting jack only on a
solid and even surface.

Not positioning the lifting jack at
the specified points can result in
damage to the vehicle. In addition,
the jack may slip off if it does not
have sufficient grip - risk of injury!

Never start the engine if the vehi-
cle is lifted - risk of accident.

Never lie under the vehicle if the
vehicle is only lifted with the vehicle
lifting jack.

It is important to support the ve-
hicle with suitable supporting blocks
if you wish to work under the lifted
vehicle - risk of injury! -
If the surface is soft, place a large
solid base below the foot of the jack.
- Rotate the crank to raise the claws of the jack sufficiently so that the jack can just
still be fitted below the car.
- The claw of the jack must be fitted around the vertical web of the lower sill
so that the jack cannot slip off when the
car is raised.
- The base of the jack should be resting fully on a firm surface.
- Align jack and at the same time raise the claw of the jack further until the claw is
touching the web.

FusesThe individual electrical circuits are pro-
tected by fuses.
The fuses are located on the left-hand face
end of the instrument cluster below the co-
ver.
Space is provided on the right for spare fu-
ses - see page 168.
Additional fuses are located in the engine
compartment on the battery. We recom-
mend having these fuses replaced by a
Škoda Dealer.Replacing a fuse
Switch off the ignition and the relevant
electrical component.

To remove the cover, place a screwdriver
against the cover (arrow on cover) and ca-
refully lever it off.

Refer to the list of fuses as shown in il-
lustration to find which fuse belongs to the
faulty component - see illustration on page
168.

Remove the blown fuse.

A blown fuse is recognizable from the
melted metal strip - replace with a new fuse
of the same rating.
Notes

If a newly inserted fuse blows again af-
ter a short time, the electrical system should
then be inspected as soon as possible by
a Škoda Dealer.

On no account „repair“ fuses as this may
cause major damage to another point of the
electrical system.

Certain of the electrical components
listed are fitted only to particular model
versions or are optional equipment.

We recommend always carrying with
you a box with replacement fuses, which is
available from Škoda Dealers
1).
1)In certain countries the box with replacement
fuses is part of the basic equipment.
Warning
If the fire extinguisher is not correctly
attached, in case of sudden manoeu-
vres or an accident, it can be thrown
through the interior compartment
and cause injuries.

Interior light (rear)*
Insert a screwdriver between light and
headlining - see arrow. Carefully press out
the light.

Turn the socket in the rear of the light to
the left and take out.

Pull faulty bulb out of the socket.

Insert new bulb.

Insert the socket again into the light and
turn fully to the right.

Insert light first of all at the side oppo-
site the arrow and then press into the head-
lining.
Jump-startingIf the engine does not start because the
battery is discharged, it is possible to use
jump-start cables to start the car with the
battery of another vehicle. Pay attention to
the following points in this case:

Both batteries should have a rated volt-
age of 12 V. The capacity (Ah) of the bat-
tery supplying the power must not be sig-
nificantly less than the capacity of the dis-
charged battery.

Only jump-start cables with an ad-
equately large cross-section should be
used. Pay attention to the instructions of
the cable manufacturer.

We recommend purchasing the jump-
start cable as a Genuine Škoda Accessory
or in sales outlets of the battery manufac-
turer.

Use only jump-start cables with insulated
clamps. A discharged battery may already freeze
if there is only slight frost. Before con-
necting the jump-start cables, it is es-
sential to thaw out a frozen battery oth-
erwise it might explode.


Run the engine of the vehicle supplying
the current.

It is essential to connect the jump-start
cables in the following sequence:
1. One end of the ( +) cable (usually red) to
the ( +) terminal of the discharged battery.
2. Other end of the red ( +) cable to the ( +)
terminal of the battery supplying the cur-
rent.
3. One end of the ( -) cable (usually black)
to the ( -) terminal of the battery supplying
the current.
4. Other end of the black ( -) cable to a solid
metal part bolted to engine block or to the
engine block itself.

178DO-IT-YOURSELFA - Discharged battery
B - Battery supplying current
Warning
Do not connect the cable to the nega-
tive terminal (-) of the discharged
battery. This can produce sparks
when the engine is started which
might ignite the gas flowing out of
the battery.
Do not affix the cable end 4 to parts
of the fuel and brake system. Warning


The non-insulated parts of the ca-
ble clamps must not touch one an-
other on any account. In addition, the
jump-start cable attached to the posi-
tive terminal of the battery must not
come into contact with electrically
conducting parts of the vehicle - risk
of short circuit!

Route the jump-start cables so
that they cannot come into contact
with rotating parts in the engine com-
partment.

Do not bend over the batteries -
risk of acid burns!

Keep sources of ignition (naked
flames, burning cigarettes etc.) well
away from the battery - risk of explo-
sion!

Start the engine as described in the sec-
tion „Starting engine“.

If the engine does not start right away,
do not crank the starter for more than 10
seconds and then wait about 30 seconds
before making a further attempt.

Once the engine is running, disconnect
both cables in exactly the reverse order.
Tow-starting/towingThe towing eyes are located at the rear right
below the bumper and at the front - see
arrow.
A tow rope or tow bar should be attached
only to these towing eyes.

Remove a ventilation grille before using
the front towing eye. Ventilation grille is held
in place with plastic spring catches in the
area of the arrow. Ventilation grille can be
removed by hand.

Grasp the top part of the grille, press
grille off in direction of arrow 1 and take out
in direction of arrow 2.

After using the towing eye, insert the
ventilation grille into the guides and press
on.

DO-IT-YOURSELF
It is not recommended to tow-start the
vehicle (despite observing the instruc-
tions which are given in the Owner’s
Manual) in view of the fact that severe
engine damage may result in certain cir-
cumstances.
It is best to attempt to start the engine
by using jump-starting cables - refer to
page 177 of the Owner’s Manual - or to
call on the services of SERVICE Mobil.
General information

The tow rope should be elastic so that
there is no strain on either vehicle. It is best
to use only plastic fibre ropes or ropes
made of a similarly elastic material. It is
important to ensure that no impermissible
pulling forces and no sudden shock loads
occur. If attempting to tow a car which is
not on a paved road, there is always a risk
of the parts of the car to which the tow rope
is attached being subjected to excessive
stress and damaged.

Before attempting to start the engine
by tow-starting the car, always use the
battery of another vehicle as a jump-
starting aid if possible - see page 177. It is essential to pay attention to the follo-
wing points when tow-starting and to-
wing the car:


Observe any legal regulations regarding
towing another vehicle.

Both drivers should be acquainted with
the special features of towing a vehicle.
Persons not familiar with towing a vehicle
should not attempt to tow-start or tow a car.

If a tow rope is used, the driver of the
towing vehicle should engage the clutch
particularly softly when moving off and shift-
ing gears.

The driver of the towed car should en-
sure that the tow rope is always taught.

The ignition of the towed car should be
switched on so that the steering wheel is
not blocked and the turn signal lights, the
windscreen wipers, horn, lights and other
electrical components can be switched on.

As the brake servo unit only operates
when the engine is running, note that suffi-
ciently greater force is required to depress
the brake pedal when the engine is not run-
ning and the steering is also much more
difficult to operate.
For technical reasons, it is not possible
to tow-start a car fitted with an automatic
gearbox.
In the event of a defect in the gearbox,
your vehicle no longer contains lubri-
cant, the car must be towed with the
driving wheels lifted or on a special
transporter or trailer.

180DO-IT-YOURSELFAdditional points for the driver of the to-
wed vehicle to note during tow-starting:

Before starting to tow the car, engage
3rd or 4th gear, depress clutch pedal and
hold. The ignition should be switched on.

Once both vehicles are moving, release
the clutch pedal.

As soon as the engine has started, de-
press clutch pedal and take the car out of
gear to avoid running into the towing vehi-
cle.

If your car is fitted with a catalytic con-
verter, the engine must not be started by
towing the car over a distance of more
than 50 m (150 ft) if the catalytic con-
verter is warm otherwise uncombusted
fuel may get into the catalytic converter
and cause damage. Pay attention to the following points if
towing a car fitted with an automatic
gearbox:


Move the shift lever into position „N“.

The maximum towing speed is 50 km/h
(30 mph).

The maximum towing distance is 50 km
(30 miles)!

If the car has to be towed over a greater
distance, the front wheels should be raised
clear of the ground.
The gear oil pump does not operate when
the engine is not running; consequently, the
gearbox is not sufficiently lubricated when
running at high speeds and over lengthy
distances.

If the car is towed by a tow truck, the front
wheels should always be raised clear of the
ground.
If the rear wheels are raised clear of the
ground, the drive shafts will rotate in the
opposite direction. As a result, the gears in
the automatic gearbox will run at such high
speeds that the gearbox could suffer se-
vere damage within a short time.
