Cooling system
Coolant
The job of the coolant is to cool the engine.
The cooling system does not require any maintenance under normal oper-
ating conditions. The coolant consists of water with a concentration of
antifreeze agent of 40 %. This mixture not only provides antifreeze protec-
tion down to -25°C but also protects the cooling and heating system from
corrosion. It also prevents the formation of scale and significantly
increases the boiling point of the coolant.
You must therefore not reduce the concentration of antifreeze agent in the
coolant by adding water, also not during the summer months or in coun-
tries with a warm climate. The concentration of antifreeze agent in the
coolant must be at least 40%.
You can increase the amount of antifreeze in the coolant iIf a higher
concentration of antifreeze is necessary for climatic reasons but only up
to 60% (antifreeze protection down to approx. -40°C). The antifreeze
protection tails off above that concentration.
Vehicles exported to countries with a cold climate (e.g. Sweden, Norway,
Finland) are already factory-filled with a coolant which offers antifreeze
protection down to about -35°C.
Coolant
The cooling system is factory-filled with TL 774-F (G12 PLUS) coolant -
colour purple - .
We recommend that you use the same antifreeze agent - G12 PLUS
(purple in colour).
Please contact your Škoda dealer if you have any questions regarding the
coolant or if you wish to fill up with a different coolant. Your Škoda dealer can also supply you with the correct coolant additives.
Caution
•Other coolant additives may cause operational problems which,
in particular, involves significantly reducing the anticorrosion effect.
•Any faults or problems resulting from corrosion may cause a loss
of coolant and, as a consequence of this, result in major engine
damage.
Inspecting the coolant level
The coolant expansion bottle is located in the engine compart-
ment on the left.
– Switch the engine off.

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 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.

Accessories, changes and replacement of parts

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!

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 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.
