Taking care of your vehicle and cleaning the vehicle
236
Chrome parts
First clean the chrome parts with a damp clotch and then polish them with
a soft, dry cloth. If it does not prove to be adequate, use a chrome care
product from Škoda original accessories.
Caution
Do not polish the chrome parts in a dusty environment, otherwise they can
be scratched.
Paint damage
Slight damage to paintwork such as scratches, scuffs or traces of chip
damage must be touched up immediately with paint (Škoda painting pen)
before any corrosion can result. You can of course have this work carried
out by a Škoda dealer.
Škoda dealers have a range of matching touch-up pens or spray cans
available in the colour of your vehicle.
The paint number of the original paintwork of your vehicle is indicated on
the vehicle data sticker ⇒page 303.
Any corrosion which has already have formed must be removed thor-
oughly. Apply a corrosion protection primer and then the paint to the
affected point. You can of course have this work carried out by a Škoda
dealer.
Plastic parts
External plastic parts are cleaned by normal washing. Plastic parts and
synthetic leather can also be treated with special solvent-free plastic
cleaning agents if a damp cloth is not sufficient. Paint care products are
not suitable for plastic parts.
Caution
Solvent-free cleaners attack the material and can damage it.
Windows
Only use a plastic ice scraper for removing snow and ice from the
windows and mirrors. You should not move the ice scraper forward and
backward but in one direction on the window which you are cleaning in
order to avoid any damage to the surface of the glass.
You can best remove residues of rubber, oil, grease, wax or silicone by
using a special window cleaner or a special silicone remover.
You should also clean the windows regularly from the inside.
Do not use window leathers which you have used 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 preservative from Škoda genuine accessories
offered by your Škoda dealer.

Caution
•Engine cleaning may only be undertaken when the ignition is off.
•It is recommended to cover the generator before washing the engine
compartment.
For the sake of the environment
The dirty water produced by washing the engine has washed away petrol,
and residues of grease and oil and should therefore be cleaned by an oil
separator. This is why engine washing should only be undertaken in a
specialist garage or at a fueling station (when these are fitted with the
required equipment).
Care of the interior of vehicle
Plastic parts, artificial leather and cloths
You can clean plastic parts and artificial leather with a moist cloth. You
should only treat such parts with special solvent-free plastic cleaning
and care products it does prove to be adequate.
Upholstery cloth and cloth trim on the doors, 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 accesso-
ries offered by your Škoda dealer.
Caution
Solvent-free cleaners attack the material and can damage it.
Fabric covers of electrically heated seats
Do not clean the seat covers wet as this may result in damage to the seat
heating system.
Clean such covers using special 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 spoonfuls of pH-neutral 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.

Fuel
246
Caution
•Remove any fuel which has spilled onto the paintwork of your vehicle
immediately - risk of paint damage!
•Vehicles fitted with catalytic converter should never be allowed to let
the fuel tank to 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.
For the sake of the environment
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. You should not
continue refuelling - otherwise the expansion chamber in the fuel tank will
also be filled with fuel. Fuel might flow out of the tank when it heats up.

Inspecting and Replenishing253
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Changing engine oil
The engine oil must be changed at the intervals stated in the Service
schedule or according to the service interval indicator ⇒page 16.
WARNING
•Only carry out the engine oil change, if you have the required
professional knowledge!
•Read and observe the warning notes ⇒page 248, “Working in
the engine compartment” before working in the engine compart-
ment.
•Let the engine cool down - risk of burning from hot oil.
•Wear an eye protection - risk of caustic burns due to oil
splashes.
•Oil is toxic! Store old oil in a safe place out of the reach of chil-
dren and unauthorized persons until you dispose of it properly.
Caution
You must not pour any additives into the engine oil - risk of engine
damage! Damage, which results from such product, are excluded from the
warranty.
For the sake of the environment
•You must on no account pour oil into the ground or into the sewage
system.
•In view of the problems involved in properly disposing of old oil, the
material, equipment and the knowledge required for such work, we recom-
mend that you have the oil and oil filter change carried out by your Škoda
dealer.
Note
After your skin has come in contact with the oil, you must thoroughly wash
your skin.
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
coolant additive 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 coolant additive 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. In these countries the concentration of
coolant additive should be at least 50 %.

Inspecting and Replenishing255
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
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
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 248, “Working in the
engine compartment” before working in the engine compartment.
Caution
One should contact a specialist garage 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 ⇒fig. 194 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 the system, must comply with
one specific specification
⇒page 253, “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 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.
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!
•The coolant additive and thus all of the coolant is harmful to
your health. Avoid contact with the coolant. Coolant vapours are
also harmful to the he alth. It is important, therefore, to always
safely store any coolant additive in its original container out of the
reach of children - risk of poisoning!
•If any splashes of coolant get into your eyes, rinse out your eyes
immediately with clear water and contact a doctor as soon as
possible.
•You should also consult a doctor without delay if you have inad-
vertently swallowed coolant.
