Care and cleaning
General
Proper care retains the value of your vehicle.
Regular and proper care retains the value of your vehicle. It may also be
one of the requirements for the acceptance of warranty claims relating to
corrosion damage and paint defects on the bodywork.
You can obtain the necessary care products from Škoda dealers. Please
follow the instructions for use on the package.
WARNING
•Care products may be harmful to your health if not used
according to the instructions.
•Always store care products in a safe place, out of the reach of
children - risk of poisoning!
For the sake of the environment
•Always select environmentally-friendly products when purchasing
vehicle care products.
•Do not dispose of residues of care products in domestic waste.
Care of the exterior of vehicle
Washing the vehicle
Frequent washing protects your vehicle.
The best protection for your vehicle against harmful environmental influ-
ences is frequent washing and wax treatment. How often you should
wash your vehicle depends on a wide range of factors, such as:
•Frequency of use
•The parking situation (garage, below trees etc.)
•Season of the year
•Weather conditions
•Environmental influences
The longer insect residues, bird droppings, tree sap, road and industrial
dust, tar, soot particles, road salt and other aggressive deposits remain
adhering to the paintwork of your vehicle, the more detrimental their
destructive effect can be. High temperatures, such as those caused by
intensive sun's rays, accentuate this caustic effect.
It may therefore be necessary, in certain circumstances, to wash the car
once a week. It may also be sufficient, however, to wash the car once a
month followed by appropriate wax treatment.
It is essential to also thoroughly wash the underside of your vehicle at
the end of the winter road salting and gritting period.

Care and cleaning

WARNING
When washing your vehicle in the winter: Water and ice in the brake
system can affect the braking efficiency - risk of accident.
Automatic vehicle wash systems
The paintwork of the vehicle is sufficiently resistant that the vehicle can be
washed normally in automatic vehicle wash plants without any problem.
The actual stress to which the paintwork is subjected, however, depends
greatly on the design of the vehicle wash system, the filtering of the water
and the type of washing and care products used. If the paintwork of your
vehicle appears mat after being washed or even has scratches, point this
out to the operator of the vehicle wash plant. Use a different vehicle wash
plant, if necessary.
There are no particular points to note before washing your vehicle in such
a plant other than the usual precautionary measures (closing windows
and sliding/tilting roof, moving any factory-fitted aerials down flat against
the bodywork, etc.).
If you have any particular attached parts fitted to your car - such as spoiler,
roof rack system, two-way radio aerial - it is best to first of all consult the
operator of the car wash plant.
It is important to degrease the lips of the windscreen wiper rubbers after
passing through the automatic vehicle wash system.
Caution
Do not screw the swivelling down roof aerial tight before washing the
vehicle in an automatic vehicle wash system - risk of damage!
Washing vehicle by hand
It is important to first soften the dirt with plenty of water and rinse it off as
thoroughly as possible before washing your vehicle by hand.
One should then clean the vehicle using a soft washing sponge,
washing glove or a washing brush and only slight pressure. Work from
the top to the bottom - beginning with the roof. Only place slight pressure
on the vehicle paintwork during cleaning Only use a shampoo for stub-
born dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for
such areas.
Rinse off the vehicle well after giving it a wash and dry it off using a
chamois leather.
WARNING
•The ignition should always be switched off when you wash your
vehicle - risk of accident!
•Protect your hands and arms from sharp-edged metal parts
when you are cleaning the underfloor, the inside of the wheel hous-
ings or the wheel trims - risk of cuts.
Caution
•Do not wash your vehicle in bright sunlight - risk of paint damage.
•Ensure that the jet of water is not aimed directly at the locks or at the
door and panel joints if you spray your vehicle in winter down with a hose
- risk of freezing.
•Do not use any insect sponges, rough kitchen sponges or similar
cleaning products - risk of damage to the surface of paintwork.

Care and cleaning197
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
For the sake of the environment
Only wash your vehicle at washing bays specifically reserved for this
purpose. This ensures that no water which may be contaminated by oil
flows into the sewage system. It is not even permitted to wash your vehicle
in certain areas except at such specific washing bays.
Washing with a high-pressure cleaner
When you wash your vehicle with a high-pressure cleaner, it is essential
to comply with the instructions for use of the cleaning equipment. This
applies in particular to the pressure used and to the spraying distance .
Maintain a sufficiently large distance to soft materials such as rubber
hoses or insulation material.
On no account use circular spray nozzles or so-called dirt cutters !
WARNING
It is particularly important that you do not clean tyres with circular
spray jets. Damage may occur even at a relatively large spraying
distance and if sprayed only for a short time!
Caution
The water must be no hotter than 60°C, otherwise the vehicle can be
damaged.
Wax treatment
Good wax treatment is an effective way of protecting the paintwork from
harmful environmental influences and minor mechanical damage.
The vehicle must be treated with a high-quality hard wax polish at the
latest, when no more drops form on the clean paintwork.
A new layer of a high-quality hard wax polish can be applied to the clean
bodywork after it has dried thoroughly. Even if you use a wax preserver
regularly we still recommend that you treat the paintwork of the vehicle at
least twice a year with hard wax.
Caution
Never apply wax to the windows.
Polishing
Polishing is only necessary if the paintwork of your vehicle has become
unattractive and if it is no longer possible to achieve a gloss with wax
preservers.
You must treat the paintwork with a wax preserver if the polish you use
does not contain any preserving elements ⇒page 197, “Wax treatment”.
We recommend using a preservative from Škoda genuine accessories
offered by your Škoda dealer.
Caution
•You must not treat mat painted parts or plastic with polishing products
or hard wax.
•Do not polish the paintwork of the vehicle in a dusty environment,
otherwise the paintwork can be scratched.

Care and cleaning
200
WARNING
One should remember when cleaning the wheels that moisture, ice
and road salt may adversely affect braking efficiency - 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 wheel vibration which is transmitted to
the steering wheel which, in certain circumstances, can cause premature
wear of the steering. It is therefore important to clean dirty wheels.
Underbody protection
The underside of your vehicle is protected for life against chemical and
mechanical influences.
One cannot, however, completely rule out damage to the protective layer
when driving so we recommend that you inspect the protective layer on
the underside of your vehicle and on the chassis at certain intervals - this
is best done at the beginning and end of the winter - and to touch up any
damaged areas.
Škoda dealers have suitable spray products available as well as the
necessary equipment and are familiar with the instructions for its use. It is
therefore best to have such touch-up work or additional corrosion protec-
tion measures carried out by a Škoda dealer.
WARNING
Never use additional underbody protection or corrosion-protection
agents for the exhaust pipes, catalytic converters or heat shields.
Such substances might ignite when driving - risk of fire!
Protection of hollow spaces
All the cavities of your vehicle which are at risk from corrosion are
protected for life by a layer of protective wax applied in the factory.
This wax protection does not require to be inspected or re-treated. Please
remove any small amount of wax which flows out of the cavities at high
temperatures with a plastic scraper and clean the spot using petroleum
cleaner.
WARNING
Safety and environmental protection regulations should observed
when using petroleum cleaner to remove wax - a risk of fire!
Engine compartment
Good corrosion protection is very important, particularly in winter when
one often drives over its salt-strewn roads. One should therefore clean the
whole engine compartment and the radiator tank before and after the salt
spreading period and treat with preservative in order to prevent the salt
from being destructive.
Škoda dealers have the cleaning agents and preservatives recommended
by the manufacturer and also the required equipment.
WARNING
•It is necessary to observe the guidelines given in the chapter
before working on the engine compartment ⇒page 209.
•Let the engine cool down before cleaning the engine compart-
ment.

Belt webbing which has become severely soiled may prevent the inertia
reel from reeling up the belt properly.
WARNING
•The seat belts must not be removed for cleaning.
•Never clean the seat belts chemically as dry cleaning may
destroy the fabric. The seat belts must also not be allowed to come
into contact with corrosive liquids (such as acids etc.).
•Seat belts which have damage to the webbing, the connections,
the inertia reel or the lock should be replaced by a Škoda dealer.
•Inertia reel belts must be completely dried before being reeled
up.

Fuel
206
Prewarming fuel
The vehicle is fitted with a fuel filter prewarming system. This secures
operation of a vehicle using diesel fuel down to an environmental temper-
ature of -25°C.
Biofuel
We recommend refuelling with diesel fuel at temperatures below -10°C.
Caution
It is not permitted to add the various fuel additives on the market, including
petrol, to diesel fuel in order to improve its flow properties.
