Cavity protectionRead and observe
and on page 177 first.
All the cavities of your vehicle which are at risk from corrosion are protectedfor life by a layer of protective wax applied in the factory.
This wax protection does not need to be inspected or re-applied.
If any small amount of wax flow out of the cavities at high temperatures, these
must be removed with a plastic scraper and the stains cleaned using a petrole-
um cleaner.
WARNINGSafety regulations should be observed when using petroleum cleaner to re-
move wax – risk of fire!
Jack
Read and observe
and on page 177 first.
The jack is maintenance-free.
If necessary, the moving parts of the jack should be lubricated with a suitable lubricant.
Wheels
Read and observe
and on page 177 first.
Wheel rims
Also thoroughly wash the wheel rims when washing the vehicle on a regular basis.
Regularly remove salt and brake abrasion, otherwise the rim material will be
corroded.
Damage to the paint layer on the wheel rims must be touched up immediately.
Light alloy wheels
After washing thoroughly and treat the wheel rims with a protective product
for light alloy wheels. Products which cause abrasion must not be used to
treat the wheel rims.
CAUTIONSevere 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.
Towing device and mounting recess
Read and observe
and on page 177 first.
Close the mounting recess with the cap to prevent any ingress of dirt.
If dirt is present, clean the inner surfaces of the mounting recess and treat
with a suitable preservative.
Always check the ball head before hitching a trailer. Apply a suitable grease, if
necessary.
Fit the protective cap when stowing away the ball head to protect the luggage
compartment against dirt.
CAUTION
Apply grease to the inner part of the mounting recess. Make sure you do not
remove any grease.
Underbody protection
Read and observe
and on page 177 first.
The underside of your vehicle is protected for life against chemical and me-
chanical influences.
When driving, it cannot be guaranteed that no damage to the protective layer
will occur.
We recommend having the protective layer underneath the vehicle and the
chassis checked — preferably before the beginning of winter and at the end of
winter.
WARNINGNever use additional underbody protection or anti-corrosion agents for ex-
haust pipes, catalytic converters, diesel particle filters or heat shields.
When the engine reaches its operating temperature, these substances may ignite - risk of fire!180General Maintenance

Regular and proper care helps to ensure efficiency and maintain the
value of
your vehicle.
We recommend using vehicle care products from ŠKODA Original Accessories.
These are available from ŠKODA Partners. The usage instructions on the pack-
age must be observed.
WARNING■ Vehicle care products may be harmful to your health if not used according
to the instructions.■
Always keep the vehicle care products safe from people who are not com-
pletely independent, e.g. children - there is a danger of poisoning!
CAUTION
■ Be sure to check clothing for colourfastness to avoid any damage or visible
stains on the material (leather), panels and textiles.■
Remove fresh stains such as those from ball-point pens, ink, lipstick, shoe
polish, etc., from the material (leather), panels and textiles as quickly as possi-
ble.
■
Air fresheners and scents can be hazardous to heath when the temperature
inside the vehicle is high.
■
Do not attach scent dispensers or air fresheners to the dash panel – risk of
damage to the dash panel.
■
Do not stick any stickers on the inside of the rear windows, the rear side win-
dows and in the vicinity of the heating elements on the windscreen or near the
window aerial. These may get damaged.
■
Do not clean the roof panelling with a brush – risk of damage to the surface
of the panelling.
■
Cleaner that contain solvents can damage the material being cleaned.
■
Apply only a small amount of the cleaning and care product.
For the sake of the environmentUsed cans of vehicle care product represent hazardous waste that is harmful
to the environment. These must be disposed of in accordance with national
legislation.
Note
Because of the special tools and knowledge required, and to avoid any poten-
tial problems with the cleaning and care of the interior of your vehicle, we rec-
ommend that cleaning and care of the interior of your vehicle be carried out by
a ŠKODA Service Partner.
Natural leather
Read and observe
and on page 181 first.
Leather is a natural material with specific properties, and requires regular
cleaning and maintenance.
The leather should be cleaned on a regular basis depending on the amount of
wear-and-tear.
Dust and dirt in the pores and folds act as abrasive materials. This leads to se-
vere corrosion and the premature brittleness of the leather surface.
We recommend that you remove dust regularly and at short intervals using a
cloth or vacuum cleaner.
Clean soiled leather surfaces with a water-dampened cotton or woollen cloth
and then dry with a clean, dry cloth »
.
Clean severely soiled areas with a cloth soaked in a mild soap solution (2 ta-
blespoons of neutral soap to 1 litre of water).
To remove stains, use a cleaning agent specially designed for this purpose.
Treat the leather regularly and at suitable intervals using a suitable leather
care product.
CAUTION
■ Ensure that no part of the leather is soaked through during cleaning and that
no water gets into the seams. Otherwise, the leather could become brittle or
cracked.■
Avoid leaving the vehicle for lengthy periods in bright sunlight to avoid the
leather from bleaching. If the vehicle is parked in the open for lengthy periods,
protect the leather from direct sunlight by covering it. 
181Car care

■Sharp-edged objects on items of clothing such as zip fasteners, rivets, sharp-
edged belts, jewellery and pendants may leave permanent scratches or signs
of rubbing on the surface. Such damage cannot be subsequently recognised as
a justified complaint.■
The use of an additional mechanical steering wheel lock may damage the
leather surface of the steering wheel.
■
Use a care cream with light blocker and impregnation effect on a regular ba-
sis and each time after cleaning. The cream nourishes the leather, allows it to
breathe and keeps it supple and also provides moisture. It also creates surface
protection.
■
Some clothing materials, e.g. dark denim, do not have sufficient colour fast-
ness. This can cause damage or clearly visible discolouration to seat covers,
even when used correctly. This applies particularly to light-coloured seat cov-
ers. This does not relate to a fault in the seat cover, but rather to poor colour
fastness of the clothing textiles.
Note
When using the vehicle, minor visible changes may occur to the leather parts
of the covers (e.g. wrinkles or creases) as a result of the stress applied to the
covers.
Synthetic leather, fabrics and Alcantara ®
Read and observe
and on page 181 first.
Artificial leather
Clean artificial leather with a damp cloth.
If this method does not completely clean the artificial leather, use a mild soap
solution or cleaning products specially designed for this purpose.
Fabric
Clean upholstery cover materials and cloth trims on doors, boot cover, etc. us-
ing specific cleaning agents, e.g., dry foam.
Use a soft sponge, brush, or commercially available microfibre cloth.
Use a cloth and special detergent to clean the headlining.
Remove any lumps on the cover fabric and any fabric residue using a brush.
Remove stubborn hair using a “cleaning glove”.
Alcantara ®
Dust and fine dirt particles in pores, creases and seams may chafe and damage
the surface.
If you leave your vehicle parked in the open for lengthy periods, protect the Al-
cantara ®
seat upholstery from direct sunlight to prevent fading.
Minor changes in colour caused by use are normal.
CAUTION
■ Do not use leather cleaners on Alcantara ®
seat upholstery.■Do not use solvents, floor wax, shoe cream, stain remover or similar agents
on Alcantara ®
seat upholstery.■
Avoid leaving the vehicle in bright sunlight for long periods of time in order
to stop the fabric from bleaching. If the vehicle is parked outside for long peri-
ods of time, cover the fabric to protect it from direct sunlight.
■
Some clothing materials, e.g. dark denim, do not have sufficient colour fast-
ness. This can cause damage or clearly visible discolouration to seat covers,
even when used correctly. This applies particularly to light-coloured seat cov-
ers. This does not relate to a fault in the seat cover, but rather to poor colour
fastness of the clothing textiles.
Seat covers
Read and observe
and on page 181 first.
Electrically heated seats
Do not clean the covers by moistening, as this can damage the seat heating
system.
Use a specific cleaning agent such as dry foam or similar to clean the covers.
Seats without seat heating
Thoroughly vacuum the seat covers with a vacuum cleaner before cleaning.
Clean the seat covers with a damp cloth or cleaning products specially de-
signed for this purpose.
Indented points arising on the fabrics by everyday use, can be removed by
brushing against the direction of hair with a damp brush.
Always clean all parts of the covers, so that there are no visible edges. Then
allow the seat to dry completely.
CAUTION
■ Regularly remove dust from the seat covers using a vacuum cleaner.■Electrically heated seats must not be dried after cleaning by switching on the
heater. 182General Maintenance

10.5 litres .
Unleaded petrol
Read and observe
and on page 183 first.
The vehicle can only be operated with unleaded petrol that meets the EN 2281)
standard.
All petrol engines can be operated using petrol with a maximum of 10% bioe-
thanol (E10).
Specified fuel - unleaded petrol 95/91 or 92 or 93 RON
Use unleaded fuel with an octane rating of 95 RON. Unleaded petrol with the
octane ratings 91 or 92 or 93 RON can also be used, but may result in a slight
loss in performance and slightly increased fuel consumption .
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded fuel with an octane rating of 95 RON or higher.
If unleaded gasoline is not available with the octane number 95 RON, in an
emergency petrol with the octane rating of 91 or 92 or 93 RON can be used to
fill the tank, but this leads to a slight loss of performance and a slightly in-
creased fuel consumption »
.
Prescribed fuel - unleaded fuel 98/95 RON
Use unleaded fuel with an octane rating of 98 RON or higher. Unleaded petrol
95 RON can also be used but results in a slight loss in performance.
In an emergency, if unleaded petrol with an octane rating of 98 RON or 95 RON
is not available, you may refuel with petrol with an octane rating of 91 or 92 or
93 RON »
.
Fuel additives
Unleaded petrol complying with EN 228 1 )
meets all the conditions for a smooth
running engine. We therefore recommend that no fuel additives are used. This
can result in considerable damage to parts of the engine or the exhaust sys-
tem. 
1)
In Germany also DIN 51626-1 or E10 for unleaded petrol with octane rating 95 or 91 or DIN 51626-2 or E5
for unleaded petrol with octane rating 95 or 98.
184General Maintenance

CAUTION■Just filling the tank once with diesel fuel that does not comply with the
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system!■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is used, do not start the engine or switch on the
ignition! Engine parts could be significantly damaged!
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with biofuel RME, therefore this fuel must
not be filled in the tank and used for driving the vehicle. The use of biofuel
RME can cause considerable damage to parts of the engine or fuel system.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents), into the diesel. This can result in considerable damage to parts of the
engine or the exhaust system!

Clear water is not sufficient to intensively clean the windscreen and head-
lights. We recommend using clean water together with a screen cleaner from
the range of ŠKODA Original Accessories (with antifreeze in winter), which will
remove any stubborn dirt.
The washing water should always be mixed with antifreeze in winter even if
the vehicle has heated windscreen washer nozzles.
Under exceptional circumstances, methylated spirits can also be used if no
screen cleaner with antifreeze is available. The concentration of methylated
spirits must not be more than 15 %. The freeze protection at this concentration
is sufficient only to -5 °C. 

SymbolMeaningKeep fire, sparks, open flames and lit cigarettes well clear of the
vehicle battery.When charging the vehicle battery, a highly explosive gas mixture
is produced.Keep children away from the vehicle battery.WARNINGThere is risk of injuries, poisoning, chemical burns, explosions or fire when
working on the battery and on the electrical system. It is essential to com-
ply with the generally applicable rules of safety as well as the warning in-
structions outlined below.■
Keep the vehicle battery away from people who are not completely inde-
pendent, especially children.
■
Do not tilt the battery otherwise battery electrolyte may flow out of the
battery vent openings. Protect your eyes by wearing safety goggles or a
face shield – risk of blindness!
■
Always wear protective gloves, eye and skin protection when handling
the vehicle battery.
■
The battery acid is strongly corrosive and must, therefore, be handled
with the greatest of care.
■
Corrosive fumes in the air irritate the air passages and lead to conjunctivi-
tis and inflammation of the air passages in the lungs.
■
Battery acid corrodes dental enamel and, if it comes into contact with the
skin, causes deep wounds that take a long time to heal. Repeated contact
with diluted acids causes skin diseases (inflammations, ulcers, skin cracks).
■
If any battery acid comes into contact with your eyes, rinse the affected
eye immediately with clean water for several minutes and consult a doctor
immediately!
■
Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. If you swal-
low battery acid, consult a doctor immediately!
WARNING■ It is prohibited to work with naked flames or lights.■It is prohibited to smoke or carry out any activities that produce sparks.■
Never use a damaged vehicle battery – risk of explosion!
WARNING (Continued)■Never charge a frozen or thawed vehicle battery – risk of explosion and
chemical burns!■
Replace a frozen vehicle battery.
■
Never jump-start vehicle batteries with insufficient acid levels – risk of
explosion and chemical burns.
WARNING■ When you charge a battery, hydrogen is released, and a highly explosive
gas mixture is also produced. An explosion can be caused through sparkling
over during unclamping or loosening of the cable plug while the ignition is
on.■
Creating a bridge between the poles on the battery (e.g. with a metal ob-
ject or cable) creates a short circuit - risk of melting the lead bars, and risk
of explosion, battery fire and acid splashes.
■
Avoid creating sparks when working with cables and electrical devices.
Strong sparking represents a risk of injury.
■
Before carrying out any work on the electrical system, switch off the en-
gine, the ignition and all electrical components and disconnect the negative
terminal (-) on the battery.
CAUTION
Improper handling of the battery can lead to damage. We recommend having
all work on the vehicle battery carried out by a specialist garage.
CAUTION
■ The vehicle battery must only be disconnected if the ignition is switched off,
otherwise the vehicle's electrical system (electronic components) can be dam-
aged. When disconnecting the battery from the electrical system, first of all
disconnect the negative terminal (-) of the battery, and then the positive ter-
minal (+).■
When connecting the battery to the electrical system, first of all connect the
positive terminal (+) of the battery, and then the negative terminal (-). Under
no circumstances must the battery cables be connected incorrectly – risk of a
cable fire.
■
Ensure that battery acid does not come into contact with the bodywork – risk
of damage to the paintwork.
■
Do not place the battery in direct daylight in order to protect the vehicle bat-
tery housing from the effects of ultra-violet light. 
194General Maintenance

CAUTIONFor technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked.
Note
The battery acid level is also checked regularly by a specialist garage as part of
the inspection service.
Charging
Read and observe
and on page 194 first.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
›
Disconnect both battery cables (“negative” first, then “positive”) only when“rapid charging” the battery.
›
Attach the terminal clamps of the charger to the battery terminals (red =
“positive”, black = “negative”).
›
Plug the mains cable of the charger into the power socket and switch the
charger on.
›
Once charging is complete: Switch off the charger and remove the mains ca-
ble from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first “positive”, then “negative”).
It is not necessary to disconnect the battery cables if you are recharging the
vehicle battery using low amperages (for example from a mini-charger). Refer
to the charger manufacturer's instructions .
A charging current of 0.1 multiple of the total vehicle battery capacity (or low-
er) must be used until full charging is achieved.
Both cables must be disconnected before charging the battery with high
amperages, known as “ rapid charging”.
The vent plugs of the vehicle battery should not be opened for charging.
WARNING“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.CAUTIONOn vehicles with the START/STOP system, the pole terminal of the charger
must not be connected directly to the negative terminal of the vehicle battery,
but only to the engine earth » page 212, Jump-starting in vehicles with the
START STOP system .
Note
We therefore recommend that vehicle batteries be rapid charged by a special-
ist garage.
Replacing
Read and observe
and on page 194 first.
The new vehicle battery must have the same capacity, voltage, current and
size as the original battery. Suitable vehicle battery types can be purchased
from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations.
