situation.
CAUTION
If you tow a trailer frequently, you should also have your vehicle inspected be-
tween service intervals.
Trailer stabilisation (TSA)
The trailer stabilisation is an extension of the stabilisation control that works
in conjunction with the counter-steering assistance to reduce the amount the
trailer "sways".
After turning on the ignition, the ESC warning light 
in the instrument cluster
illuminates for about 2 seconds longer than the ABS warning light.
Function requirements for trailer stabilisation. The trailer was shipped from the factory or purchased from the ŠKODA
genuine accessories.
The ESC is active. (Warning lights 
or 
do not illuminate in the instru-
ment cluster).
The trailer is electrically connected to the towing vehicle by means of the
trailer socket.
The speed is higher than approx. 60 km/h.
The trailer has a rigid drawbar.
WARNING■ The increased safety offered by the trailer stabilisation must not tempt
you to take greater risks than otherwise.■
Avoid abrupt and sudden driving and braking manoeuvres - there is a risk
of accidents.
CAUTION
■ The trailer stabilisation need not be able to correctly detect all of driving sit-
uations.■
Light trailers that sway are not always detected and therefore stabilised ac-
cordingly by the trailer stabilisation.
■
Release the pressure on the accelerator pedal if the system is being regula-
ted.
Note
The trailer stabilisation works for both braked and unbraked trailers.
Anti-theft alarm system
When the vehicle is locked, the alarm is activated when the electrical connec-
tion to the trailer is interrupted.
Always switch off the anti-theft alarm system before a trailer is coupled or un-
coupled » page 55 .

The best way to protect your vehicle against harmful environmental influences
is frequent washing.
How often the vehicle should be washed depends on factors such as:
› Frequency of use.
› Parking situation (garage, under trees etc.).
› Season.
› 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, ac-
centuate this caustic effect.
It is essential to also thoroughly clean the underside of the vehicle at the end
of the winter.WARNING■ When washing your vehicle in the winter: Water and ice in the braking
system can affect the braking efficiency – risk of accident!■
Only wash the vehicle when the ignition is switched off – risk of accident!
CAUTION
Do not wash your vehicle in bright sunlight – risk of paint damage.
For the sake of the environment
Only wash the vehicle at washing bays intended for this purpose.
Washing by hand
Read and observe
and on page 176 first.
Soak the dirt with plenty of water and rinse as well as possible.
Clean the vehicle with a soft sponge, a washing glove or a washing brush .
Work from the top to the bottom - starting with the roof.
Only use a car shampoo for stubborn 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.
Give the vehicle a good rinse after washing it and dry it off using a chamois
leather.
CAUTION
■ When washing the car by hand, protect your hands and arms from sharp-
edged metal parts (e.g. when cleaning the underfloor, the inside of the wheel
housings or the wheel trims, etc.) - There is a risk of cuts!■
Only apply slight pressure when cleaning the vehicle's paintwork.
176General Maintenance

Automatic car wash systemsRead and observe
and on page 176 first.
The usual precautionary measures must be taken before washing the vehicle
in an automatic car wash system (e.g. closing the windows and the sliding/tilt-
ing roof etc.).
If your vehicle is fitted with any particular attached parts, such as a spoiler,
roof rack system, two-way radio aerial etc., it is best to consult the operator of
the car wash system beforehand.
After an automatic wash with wax treatment, the lips of the wipers should be
cleaned with cleaning agents specially designed for the purpose, and then de-
greased.
WARNINGFold in the exterior mirrors to prevent damage before washing the vehicle
in an automatic car wash system. Never manually fold in electric exterior
mirrors - always use the electric controls.
Washing with a high-pressure cleaner
Read and observe
and on page 176 first.
When washing the vehicle with a high-pressure cleaner, the instructions for
use of the equipment must be observed. This applies in particular to the pres-
sure used and to the spraying distance .
Maintain a sufficiently large distance to the parking aid sensors and soft mate-
rials such as rubber hoses or insulation material.
WARNINGNever use circular spray nozzles or dirt cutters!
CAUTION
■ If washing the vehicle in the winter using a hose or high-pressure cleaner,
ensure that the jet of water is not aimed directly at the locking cylinders or the
door/panel joints – risk of freezing!■
To avoid damaging the parking aid sensors while cleaning with high-pressure
cleaners or steam jets, the sensors must only be directly sprayed for short pe-
riods while a minimum distance of 10 cm must be observed.
■ The temperature of the water used for cleaning must not exceed 60 °C – risk
of damaging the vehicle.■

177Car care

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

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. 

The capacity of the reservoir is about 3 litres or about 5.5 litres on vehicles that
have a headlight cleaning system 1)
.
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. 
1)
In some countries, 5.5 ltr. applies for both variants.
188General Maintenance

CAUTION■Under no circumstances must radiator antifreeze or other additives be added
to the windscreen washer fluid.■
If the vehicle is fitted with a headlight cleaning system, only cleaning prod-
ucts which do not attack the polycarbonate coating of the headlights must be
added to the windscreen washer fluid.

Checking the coolant level
192
Replenishing
192
The coolant consists of water with coolant additive. This mixture guarantees
antifreeze protection, protects the cooling/heater system against corrosion
and prevents lime formation.
Vehicles exported to countries with a mild climate are already factory-filled
with a coolant which offers antifreeze protection down to about -25 ℃. In
these countries, the concentration of coolant additive should be at least 40%.
Vehicles exported to countries with a cold climate 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%.
If a higher concentration of antifreeze is required for climatic reasons, the con-
centration of coolant additive can be increased up to a maximum of 60% (anti-
freeze protection down to approx. -40 °C).
When refilling, only use the same antifreeze identified on the coolant expan-
sion vessel » Fig. 167 on page 192 .
WARNINGThe engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en- gine compartment » page 186.
CAUTION
■
 Do not continue if for some reason it is not possible to fill with coolant un-
der the current circumstances! Switch off the engine and seek assistance from
a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
ventilate - there is a risk of engine damage, 
do not continue driving! Switch
off the engine and seek assistance from a specialist garage.
■
The concentration of coolant additive in the coolant must never be under
40%.
■
Over 60% of coolant additive in the coolant reduces the antifreeze protec-
tion and cooling effect.
■
A coolant additive that does not comply with the correct specifications can
significantly reduce the corrosion protection.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 167 on page 192 .
■
If a fault causes the engine to overheat, we recommend visiting a specialist
garage, as otherwise serious engine damage may occur.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
