Headlights
Before starting off with a hitched trailer, also check the setting of the headlights. Alter
the setting as necessary with the ai
d of the headlight beam adjuster page 56.
Detachable ball head
The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is
stowed together with separate fitting instru ctions in the spare wheel well in the luggage
compartment of the vehicle.
Further information on the towing device page 184.
Note

We recommend that you also have your vehicle inspected between service inter-
vals if you tow a trailer frequently.

The handbrake on the towing vehicle must be put on when coupling and decou-
pling the trailer.
Driving Tips
Particular caution is required when towing a trailer.– Do not, as far as possible, drive with your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temperature gauge if the outside temperature is high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer is
laden. Maintain a particularly low speed if you cannot avoid driving with this combina-
tion.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for countries
in which higher speeds are allowed. The fact that the driving stability of the vehicle + trailer combination reduces with
increasing speed means that the legally allowed speed should not be used when there
are unfavourable road, weather or wind cond
itions, particularly near accident black
spots.
You must always reduce your speed immediat ely as soon as you detect even just the
slightest swaying of the trailer. On no account attempt to stop the trailer from
“swaying” by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting from the
trailer wheels locking. Shift down gears in good time before negotiating a downhill
section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a
lengthy slope in a low gear at a high engi ne speed when the outside temperature is
very high  page 16, “Coolant temperature gauge”.
If the needle of the coolant temperature gauge moves into the right-hand area or even
the red area of the scale, reduce your speed immediately. Stop and switch off the
engine if the warning light
 in the instrument cluster begins flashing. Wait a few
minutes and check the level of coolant in the coolant expansion bottle page 201,
“Inspecting the coolant level”.
Please refer to the following guidelines  page 31, “Coolant temperature/coolant
level ”.
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear and
increasing the engine speed is not possible since the fan speed is independent of the
engine speed. One should also not drop a gear for this reason when towing a trailer as
long as the engine can manage th e slope without any drop in speed.

Taking care of your vehicle and cleaning the vehicle
188
Do not use window leathers which you have us ed to polish the vehicle body to dry off
the windows. Residues of preservatives in the window leather can dirty the window
and reduce visibility.
Do not affix any stickers over the inside of the rear window to avoid damage to the
heating elements of the rear window heater .
We recommend using a preserva tive from Škoda genuine accessories offered by your
Škoda dealer.
Caution
Never remove snow or ice from the glass parts with warm or hot water - risk of forma-
tion of cracks in the glass!The headlight lensesPlease do not use any aggressi ve cleaning or chemical solvent products for cleaning
the front headlights - risk of damage to the plastic lenses. Please use soap and clean
warm water.
Caution
Never wipe the headlights dry and do not use any sharp objects for cleaning the plastic
lenses, this may result in damage to the protective paintwork and consequently in
formation of cracks on the headlight lenses, e.g through effect of chemical products.Door and window sealsThe rubber seals on the doors, boot lid, bonnet and windows remain supple and last
longer if you treat them from time to time with a rubber care product (e.g. with a spray
with silicone-free oil). You also avoid premature wear of the seals and prevent leakages
in this way. It is also easier to open the doors. Rubber seals which are well cared for also
do not stick together in cold winter weather.Locking cylinderWe recommend that you use the spray from Škoda original accessories with regreasing
and anticorrosive effect for de-icing locking cylinders.
Note
When washing your vehicle, ensure that as little water as possible gets into the locking
cylinders.WheelsSteel wheels
You should also thoroughly wash the wheels and wheel trims when giving your vehicle
its regular wash. This prevents any brake dust, dirt and road salt from sticking to the
wheel hubs. You can remove stubborn brake abrasion adhering to the wheels with an
industrial cleaner. Touch up any damage to the paintwork on the wheels before rust is
able to form.
Light alloy wheels
Regular care of light alloy wh eels is necessary in order to retain their decorative
appearance over long periods. It is particul arly important to remove regularly any road
salt and brake abrasion from light alloy wheels, otherwise the light metal will suffer.
Wash thoroughly and then treat the wheels with a protective product for light alloy
wheels which does not cont ain any acidic components. We recommend to apply a
hard wax layer onto the wheel hubs every three months. You must not use any prod-
ucts which cause abrasion when treating the wheel hubs. Any damage to the paint
layer on the wheel hubs must be touched up immediately.
We recommend using a preservative from Šk oda genuine accessories offered by your
Škoda dealer.
WARNING
One should remember when cleaning th e wheels that moisture, ice and road
salt may adversely affect braking ef ficiency - risk of an accident!
Note
Severe layers of dirt on the wheels can also result in wheel imbalance. This may show
itself in the form of a wheel vibration which is transmitted to the steering wheel which,
in certain circumstances, can cause premature wear of the steering. This means it is
necessary to remove the dirt.

Taking care of your vehicle and cleaning the vehicle
190
Upholstery cloth and cloth trim on the d oors, luggage compartment cover, headliner
etc. are best treated with special cleaning products, using if necessary a dry foam and
a soft sponge or brush.
We recommend using a cleaning product from Škoda genuine accessories offered by
your Škoda dealer.
Caution
Solvent-free cleaners attack th e material and can damage it.Fabric covers of electrically heated seatsDo not clean the seat covers moist as this may re sult in damage to the seat heating
system.
Clean such covers using specia l agents, for example dry foam.Natural leather
Natural leather requires quite particular care and attention.Leather should be treated from time to time according the following guidelines
depending on how much it is used.Normal cleaning– Clean soiled areas of the leather with slightly moistened cotton or woollen cloth.Severe soiling– Clean severely soiled areas with a cloth dipped in a mild soapy solution (2 spoon-
fuls of natural soap to 1 litre of water).
– Ensure that the leather is not soaked through at any point and that no water gets into the stitching of the seams.
– Dry off the leather with a soft, dry cloth.
Removing stains– Remove fresh stains which are water-based (e.g. coffee, tea, juices, blood etc.)
with an absorbent cloth or household paper or use the cleaner from the care set
for a stain which has already dried in.
– Remove fresh stains on a fat base (e.g. butter, mayonnaise, chocolate etc.) with an
absorbent cloth or household cleaning paper or with the cleaner from the care set
if the stain has not yet pe netrated into the surface.
– Use a grease dissolver for grease stains which have dried in .
–Eliminate special stains (e.g. ball-point pens, felt pe n, nail varnish, dispersion
paint, shoe cream etc.) with a special stain remover suitable for leather.Leather care– Treat the leather every six months with th e leather care product available from an
authorised Škoda Service Partner.
– Apply only a small amount of the care product.
– Dry the leather off with a soft cloth
It is best to consult an authorised Škod a Service Partner if you have any questions
regarding cleaning and care of the leather interior in your vehicle.
Caution

You must on no account treat the leather wi th solvents (e.g. gasoline, turpentine),
floor wax, shoe cream or such like.

Avoid leaving your vehicle for lengthy period s in bright sunlight in order to avoid
bleaching the leather. If you leave your vehicle parked in the open for lengthy periods,
protect the leather from the direct ra ys of the sun by covering it over.

Sharp-edged objects on items of clothing su ch as zip fasteners, rivets, sharp-edged
belts may leave permanent scratches or signs of rubbing on the surface.Note

Use a care cream with ligh t blocker and impregnation effect regularly and each
time after cleaning the leathe r. The cream nourishes the leather, allows it to breathe
and keeps it supple and also provides mois ture. It also creates surface protection.

WARNING
Pay attention to any legal requirements if you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for
safety reasons. The canister can be damaged in the event of an accident and fuel
may leak out.
Caution

Even inadvertently filling the fuel tank with another biofuel such as Ethanol°E85
can result in damage to the fuel system.

If you park the car for a lengthy period, fill with petrol complying with (DIN) EN°228,
because Ethanol E85 can contai n low quantities of impurities, which can lead to corro-
sion.For the sake of the environment
If you use Ethanol E85, the CO
2 emission of your vehicl e is lowered up to 5%.
Note

When operating with Ethanol E85, the fuel consumption increases by approx 33%,
as a lower quantity of energy is contained in the bioethanol than in unleaded petrol.

Biofuel Ethanol E85 contains only a low quantity of additives in contrast to
unleaded petrol. Therefore we recommend to fill up the tank with unleaded petrol
complying with EN 228 every 15 000 km (e.g . before the oil change) and run it empty,
so that the engine remains clean. Make sure not to use the whole content of the tank
 page 195, “Refuelling”.

The interval of 15 000 km applies for the oil change.
Operation in winterIf you use biofuel Ethanol E85 at very low temperatures, it is necessary to preheat the
engine before an engine start.
The power socket for the engine preheating is located in the front bumper next to the
fog light  fig. 158.
If an engine preheating is not possible at outside temperatures lower than -10 °C, the
share of unleaded petrol complying with EN 228 must be as high as possible. Thus the
cold start property of the engine is clearly improved.
If there is biofuel Ethanol E85 in the tank and the engine is not preheated, it can lead at
temperatures below -15°C to very p oor or no starting of the engine.
For the sake of the environment
The use of engine preheating at temperatures below -10°C has a positive effect on the
fuel consumption and thus on the environment.The outside temperature

fuel filler flap).
– Unscrew the fuel filler cap anti-clockwise and place the fuel filler cap from above
on the fuel filler flap fig. 159 - right.Closing fuel filler cap– Screw on the fuel filler cap by turning it to the right until it is heard to click.
– The fuel filler cap on the fuel filler tube mu st be locked to the right using the vehicle
key (only valid for vehicles which do not ha ve automatic locking of the fuel filler
flap).
– Close the fuel filler flap until it locks.
The correct grade of fuel for your vehicle as well as the tyre size and inflation pressures
are stated on a sticker affixed to the inside of the fuel filler flap. Further information on
fuel page 192. The fuel tank has a capacity of about 55°litres or 60 litres
17).
WARNING
Pay attention to any legal requirements if
you do carry a spare canister in the
vehicle. We do not recommend carrying any fuel canisters in your vehicle for
safety reasons. The canister can be damaged in the event of an accident and fuel
may leak out.
Caution

Before refuelling it is necessary to switch off the auxiliary heating system (auxiliary
heating and ventilation) *.

Remove any fuel which has spilled onto th e paintwork of your vehicle immediately
- risk of paint damage!

On vehicles fitted with a ca talytic converter, never let the fuel tank run completely
empty. An irregular supply of fuel to the engine can result in misfiring and unburnt fuel
may get into the exhaust system, which may result in overheating and damage to the
catalytic converter.

Make sure that the valve is not pressed into the filler tube when inserting the pump
nozzle into the filler tube. Otherwise you ar e unintentionally filling up the volume,
which in case of heat can cause an expansion of the fuel. This can lead to an overflow
of fuel or damage to parts of the fuel reservoir.

The fuel tank is full just as soon as the pump nozzle switches off for the first time,
provided the nozzle has been operated properly. Do not continue refuelling - other-
wise the expansion volume is filled up.


In view of the problems involved in prop erly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you have
the oil and oil filter change carried out by an authorised Škoda Service Partner.Note
After your skin has come in contact with th e oil, you must thoroughly wash your skin.Cooling systemCoolant
The job of the coolant is to cool the engine.The cooling system does not require any maintenance under normal operating condi-
tions. The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture not only provides antifreeze protection 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 mo nths or in countries with a warm climate.
The concentration of coolant additive in the coolant must be at least 40%.
You can increase the amount of antifreeze in the coolant if a higher concentration of
antifreeze is necessary for cl imatic reasons but only up to 60% (antifreeze protection
down to approx. -40°C). The antifreeze prot ection 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 of fers antifreeze protection down to about
-35°C. In these countries the concentration of coolant additive should be at least 50%.
Coolant
The cooling system is factor y-filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the same coolan t additive - G13 (purple in colour) - for
topping up the system. Please contact an authorised Škoda Serv
ice Partner if you have any questions
regarding the coolant or if you wish to fill up with a different coolant.
An authorised Škoda Service Partner can also supply you with the correct coolant addi-
tives.
Coolant capacity
Caution

Other coolant additives may cause operat ional problems which, in particular,
involves significantly reduci ng 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.Petrol engines

Technical Data
Note
On vehicles which are fitted with an indepe ndent auxiliary heating and ventilation, the
volume of the coolant is greater by approx. 1 ltr.Inspecting the coolant levelThe coolant expansion bottle is located in the engine compartment on the right.
– Switch the engine off.
– Open the bonnet page 196.
– Check the level of coolant in the coolant expansion bottle fig. 164 . The coolant
level when the engine is cold must lie between the (MIN) and (MAX) mark-
ings. The level may also rise slightly above the (MAX) marking when the engine
is warm.
If the coolant level in the reservoir is too lo w, this is indicated by the warning light in
the instrument cluster page 31, “Coolant temperature/coolant level ”. We never-
theless recommend inspecting the coolant leve l 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 specialist garage. 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.
WARNING
Read and observe the warning notes page 197, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as s oon 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 fig. 164 and
unscrew the cap carefully by turning it to the left .
–Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing th e system, must comply with one specific
specification page 200. Do not use an alternative additive if the coolant additive
G13 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 addi-
tive again by a specialist garage.
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.
