Windscreen Wiper and Washer System
The windshield washer reservoir contains the cleaning fluid for the wind-
screen and for the headlamp cleaning system*. The reservoir is located at
the front left of the engine compartment ⇒fig. 163 .
The reservoir has a capacity of 4 liters.
Clear water is not sufficient to intensively clean the windscreen and head-
lights. We therefore recommend using clean washing water together with
the screen cleaner (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 windscreen washer nozzles*.
It is also possible in exceptional cases to use methylated spirits when no
screen cleaner with antifreeze is available. The concentration of methyl-
ated spirits must not be more than 15 %. Please note, however, that the
antifreeze protection at this concentration is only adequate down to -5°C.
Caution
•On no account should you add radiator antifreeze or other additives to
the windscreen washer fluid.
•If the vehicle is fitted with headlight cleaning system, you should only
add cleaning products which do not attack the polycarbonate coating of
the headlights to the windscreen washer fluid. Please contact a Škoda
dealer, he will tell you, which cleaning product you can use.
Note
Do not take the filter out of the windscreen wash container when filling it
up again with liquid otherwise dirt can get into the liquid transportation
system and can lead to faults in operation of the windscreen wash
system.
Spark plugs
The spark plugs will also be checked as part of the Inspection Service.
Please observe the following if spark plugs have to be renewed inbetween
inspection services.
•Spark plugs and the ignition system are matched to the engine and
therefore contribute to lower emissions in the exhaust gases.
•Only use the spark plugs foreseen for the engine concerned if you wish
to avoid operational faults, engine damage and loss of approval and
licensing of the vehicle due to false exhaust gas values or unshielded
spark plugs. Particularly important parameters include the number of elec-
trodes, the thermal value and possibly also the radio frequency suppres-
sion level.

Accessories, changes an d replacement of parts
General
Škoda vehicles have been built according to the latest discoveries in
safety engineering. Thus one should not change the condition in which the
vehicle was delivered from the manufacturer without some thought.
The following guidelines should be observed when a vehicle is to be retro-
fitted with accessories, have technical changes made to it or a part has to
be replaced at some time in the future.
•Advise should always be obtained from a Škoda dealer before buying
any accessories and before making any technical changes ⇒.
•This is particularly the case when accessories are bought in a foreign
country.
•Skoda accessories which have been released for use and original
Škoda parts can be obtained from Škoda dealers. They will install them
professionally and correctly.
•All original accessories which are listed in the catalogue such as tilting
roofs, spoilers, wheels etc. must have an official stamp of approval.
•Radios, aerials and other electrical accessories should only be
installed by an authorised workshop.
•The guidelines issued by Škoda Auto must be observed when making
technical changes.
•This is to ensure that no technical damage occurs to the vehicle, that
travelling and operating safety are maintained and that the chnages are
permissible. Škoda dealers undertake this work professionally or refer it
to an specialist company in special cases.
Any damage which is done caused by technical changes made
without consulting a Škoda Auto is excluded from the warranty.
WARNING
•We advise you, in your own interest, to only use Škoda acces-
sories and original Skoda parts which have been expressly
approved for use on your Škoda. Reliability, safety and suitabiliity
have been established for these parts.
•We cannot guarantee suitability of installation into your vehicle
of other products despite keeping a constant eye on market devel-
opments (also not in the case where there is an attestation or
permission can be produced).

– Have all the occupants get out. While changing a wheel, the
occupants of the vehicle should not stand on the road (it is
better behind a crash barrier).
– Apply the handbrake firmly.
– Engage 1st gear or if your vehicle is fitted with an automatic
gearbox, position the selector lever into position P .
– If a trailer is coupled, uncouple it.
– Take the vehicle tool kit and the spare wheel ⇒ page 229
out of the luggage compartment.
Caution
If you have to change a wheel on a slope first block the opposite wheel
with a stone or similar object in order to secure the vehicle from unexpect-
edly rolling away.
Note
Comply with the national legal regulations.
Changing a wheel
Always change a wheel on a level surface as far as possible.
– Take off the full wheel trim/wheel trim cap ⇒page 232,
“Wheel trim caps*” or the caps ⇒page 232, “Wheel bolts with
caps*”.
– Slacken the wheel bolts ⇒ page 233.
– Jack up the vehicle until the wheel is clear of the ground ⇒page 233.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper etc.).
– Take off the wheel.
– Fit on the spare wheel and tighten the wheel bolts slightly.
– Lower the car.
– Tighten the wheel bolts firmly, alternately and diagonally using the wheel wrench ⇒page 233.
– Mount the full wheel trim/wheel trim cap or the caps.
Note
•All bolts must be clean and must turn easily.
•You must never grease or oil the wheel bolts!
WARNING
•If you find yourself in flowing traffic put on the hazard warning
lights system and place the warning triangle on the side of the road
at the prescribed distance from your vehicle while observing all
national legal provisions. In this way you are protecting not only
yourself but also other road users.
•Never start the engine with the vehicle sitting on the raised jack
- danger of suffering injury!

– Have the tightening torque checked with a torque wrench as
soon as possible. The tightening torque must be 120 Nm.
The safety wheel bolts on vehicles fitted with them (one safety wheel bolt
per wheel) can only be loosened or tighten up by using the adapter
provided.
It is meaningful to note the code number hammered into the rear side of
the adapter or the rear side of the safety wheel bolts. You can obtain a
replacement adapter from a Škoda Dealer, if necessary, by quoting this
number.
We recommend that you always carry the adapter for the wheel bolts with
you in the vehicle. It should be stowed in the vehicle tool kit.
Caution
Damage can occur to the adapter and safety wheel bolt if the safety wheel
bolt is tightened up too much.
Note
The set of safety wheel bolts can be obtained from your Skoda dealer as
an original accessory.
Jump-starting
Initial steps
You can use the battery of another vehicle for jump-starting yours if the
engine does not start because the battery on your vehicle is flat. You will
require jump-start cables for this purpose. Both batteries must have a rated voltage of 12 V. The
capacity (Ah) of the
battery supplying the power must not be significantly less than the
capacity of the discharged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section
and insulated terminal clamps. Please pay attention to the manufacturer's
instructions.
Positive cable - colour coding in the majority of cases red.
Negative cable - colour coding in the majority of cases black.
Note
•There must not be any contact between the two vehicles otherwise
current may flow as soon as the negative terminals are connected.
•The discharged battery must be properly connected to the system of
the vehicle.
•Switch off any mobile phone, pay attention to the instructions for use
of the mobile phone in such a situation.
•We recommend purchasing jump-start cables from a Skoda dealer as
an original accessory or from retailers who sell branded batteries.
WARNING
•A discharged battery may already freeze at temperatures just
below 0°C. It is essential to thaw out a frozen battery before you
connect the jump-start cables - risk of an explosion!
•Please pay attention to the warning instructions relating to
working in the engine compartment ⇒page 203.

Starting engine
It is important to connect the jump-start cables in the correct
order.
Connecting positive terminals
– Attach one end to the positive terminal ⇒fig. 180 of the
discharged battery .
– Attach the other end to the positive terminal of the battery supplying the power .
Connecting negative terminal and engine block
– Attach one end to the negative terminal of the battery supplying the power .
– Attach the other end to a solid metal part which is connected firmly to the engine block, or to the engine block
itself. Starting engine
– Start the engine of the vehicle providing current and run the
engine at idling speed.
– Now start the engine of the vehicle with the discharged battery.
– Interrupt the attempt at starting an engine after 10 seconds if it does not start right away and wait for about 30 seconds
before repeating the attempt.
– Disconnect the cables on the engine in exactly the reverse
order they were connected up.

WARNING
•The non-insulated parts of the terminal clamps must never
make contact with each other. Furthermore, the cable connected to
the positive terminal of the battery must not come into contact with
electrically conducting parts of the vehicle - risk of a short circuit!
•Do not affix the jump starting cables to the negative terminal of
the discharged battery. There is the risk of detonating gas seeping
out the battery being ignited by the strong spark which results
from the engine being started.
•Run the jump-start cables so that they cannot be caught by any
rotating parts in the engine compartment.
•Do not bend over the batteries - risk of caustic burns!
•The vent screws of the battery cells must be tightened firmly.
•Keep any sources of ignition (naked flame, smouldering ciga-
rettes etc.) away from the battery - risk of an explosion!

Tow-starting and towing vehicle
General
Please pay attention to the following instructions if you are going
to use a tow rope:
Driver of the towing vehicle
– Do not drive off until the tow rope is taught.
– Release the clutch particularly gently when starting off or depress the accelerator particularly gently if your vehicle is
fitted with an automatic gearbox.
Driver of th e towed vehicle
– Switch the ignition on so that the steering wheel is not blocked and you can also operate the turn signal lights, the headlight
flasher, the windscreen wipers and windscreen washer
system.
– Take the vehicle out of gear or move the selector lever into position N if your vehicle is fitted with an automatic gearbox.
– Note that the brake servo unit and power steering only operate if the engine is running. You will require significantly greater
physical force to depress the brake pedal and to steer the
vehicle if the engine is not running.
– Ensure that the tow rope is always kept taught.
Tow rope or tow bar
A tow bar is safest way of towing a vehicle and also minimizes any
shocks. You can use a tow rope only if a suitable tow bar is not available.
The tow rope must be elastic to protect the vehicle. Thus one should only
use plastic fibre rope or a rope made out of a similarly elastic material.
Attach the tow rope or the tow bar only to the towing eyes provided for
this purpose ⇒ page 239, “Towing eye” and ⇒page 239, “Rear towing
eye”.
Driving style
Towing another vehicle requires a certain amount of practice. Both drivers
should be familiar with the particular points about towing a vehicle.
Unskilled drivers should not attempt to tow-start or tow in another vehicle.
One should be constantly vigilant not to allow impermissibly high towing
forces or jerky loadings. There is always a risk of excessive stresses and
damage resulting at the points to which you attach the tow rope or tow bar
when you attempt to tow a vehicle which is not standing on a paved road.
Caution
If the gearbox of your vehicle no longer contains any oil because of a
defect, your vehicle must only be towed in with the driven wheels raised
clear of the ground, or on a special vehicle transporter or trailer.
Note
Please comply with any legal requirements particularly regarding the
switched on signal systems, when towing in or tow-starting another
vehicle.

Towing eye
The front towing eye is welded on behind the bumper on the right.
– Carefully pull the protective grille ⇒fig. 181 off in the right-
hand area of the bumper.
Rear towing eye
The rear towing eye is welded on below the rear bumper on the right.
Tow-starting a vehicle
If the engine does not start, we generally do not recommend to
tow-start your vehicle. One should attempt to start the engine using jump start cables
⇒page 236 or call on the services of the
SERVICE mobile.
If your vehicle has to be towed:
– Engage 2nd or 3rd gear with the vehicle stationary.
– Depress the clutch pedal fully and keep it depressed.
– Switch on the ignition.
– Wait until both vehicles are moving then release the clutch pedal slowly.
– Depress the clutch pedal fully when the engine fires and take the vehicle out of gear.
For technical reasons it is not possible to tow-start a car fitted with an
automatic gearbox .
Caution
Vehicles which are fitted with a catalytic converter should not be tow-
started over a distance of more than 50 metres. Unburnt fuel may get into
the catalytic converter and damage it.

WARNING
There is high risk of having an accident when tow-starting a
vehicle, when for example the towed vehicle runs into the towing
vehicle.

Towing in a vehicle fitted with a manual gearbox
Please refer to the notes ⇒page 238.
The car can be towed in with a tow bar or a tow rope or with the front or
rear wheels raised. The maximum towing speed is 50 km/h.
Towing of a vehicle with an automatic gearbox
Please refer to the notes ⇒page 238.
The car can be towed in with a tow bar or a tow rope. Pay attention to the
following points:
•Move selector lever into N .
•The maximum towing speed is 50 km/h.
•The maximum permissible towing distance is 50 km. The gear oil
pump does not operate when the engine is not running and the gear would
not be adequately lubricated at higher speeds and over longer towing
distance.
Caution
If the vehicle is towed in by a recovery vehicle, it should only be towed in
with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged!
Note
The vehicle must be transported on a special vehicle or trailer if it is not
possible to tow in the vehicle in the way described or if the towing distance
is greater than 50 km.
