CAUTION
Improperly connected trailer electrical installations may cause malfunction of
the entire vehicle electronics.
Note
■ The total power consumption of all the connected consumers on the trailer
must not exceed 350 watts.■
Coat the ball head of the towing device with a suitable grease whenever
necessary.
Loading a trailer
Distribution of the cargo
Distribute the cargo in the trailer in such a way that heavy items are located as
close to the trailer axle as possible. Secure the items from slipping.
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 combination.

Do not smoke when refuelling and do not use a mobile phone.
■
Fuel vapours are explosive - can be fatal!
CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of
fuel can cause misfiring, which can result in damage to parts of the engine and
the exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork –
risk of paint damage.
■
If the vehicle was not purchased in the country where it was intended to be
operated, you should check whether the fuel specified by the manufacturer is
offered in the country where the vehicle will be operated. You should also per-
haps check whether the manufacturer has recommended a different fuel for
operation of the vehicle in the corresponding country. If no prescribed fuel is
available, then you must check whether it is permitted by the manufacturer to
operate the vehicle with another fuel type.

Fuel additives
Unleaded petrol in accordance with the EN 228 standard 1)
meets all the condi-
tions for a smooth-running engine. We therefore recommend that no fuel ad-
ditives are used. This can result in considerable damage to parts of the engine
or the exhaust system.
CAUTION
■ Even one filling of the tank with petrol that does not meet the standards can
lead to serious damage to parts of the exhaust system!■
If a fuel other than unleaded fuel which complies to the above mentioned
standards (e.g. leaded petrol) is put in the tank by mistake, do not start the en-
gine or switch on the ignition. Extensive damage to engine parts can occur.
CAUTION
■ If petrol with a lower octane number than the one prescribed is used do not
drive with a high engine speed. A high engine load can severely damage en-
gine components.■
Even in the event of an emergency, petrol of a lower octane number than 91
RON must not be used, otherwise the engine can be severely damaged.
CAUTION
In no case may fuel additives with metal components be used, especially not
with manganese or iron content. There is a risk of causing severe damage to
parts of the engine or exhaust system.
CAUTION
Do not use fuels with metal components, such as LRP (lead replacement
petrol) may be used. There is a risk of causing severe damage to parts of the
engine or exhaust system.Note■ Unleaded petrol that has a higher octane number than that required by the
engine can be used without limitations.■
The use of petrol with an octane rating higher than 95 RON in does not re-
sult in either a noticeable increase in power nor lower fuel consumption in ve-
hicles for which unleaded petrol 95/min 92 or 93 RON is specified.
■
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of pet-
rol with a higher octane number than 95 RON can increase the power and re-
duce fuel consumption.
Diesel fuel
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap.
Read and observe
and on page 201 first.
The vehicle can only be operated with diesel fuel that meets the EN 5902)
standard.
All diesel engines can be operated using diesel fuel with at most 7% biodiesel
(B7) 3)
.
On the Indian market, your vehicle will only be able to run on diesel fuel com-
pliant with standard IS 1460/Bharat IV. If diesel fuel which complies with this
standard is not available, you can refuel with diesel fuel according to standard
IS 1460/Bharat III in case of emergency.
Operation in winter - winter-grade diesel fuel
In the cold season, only use “winter-grade diesel fuel” which will still operate
properly even at a temperature of -20 °C.
It is often the case in countries with different climatic conditions that diesel
fuels available have a different temperature characteristic. ŠKODA Partners
and filling stations in the relevant country will be able to provide you with in-
formation regarding the diesel fuels available. 

203Inspecting and replenishing

Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures opera-
tion of a vehicle using diesel fuel down to an environmental temperature of
-24 °C.
Diesel fuel additives
The diesel fuel in accordance with the prescribed standards meets all the con-
ditions for a smooth running engine. We therefore recommend that no diesel
fuel additives are used. This can result in considerable damage to parts of the
engine or the exhaust system.
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 put into the tank, do not start the engine or
switch on the ignition! Extensive damage to engine parts can occur.
■
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 refuelled and driven. 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.

In order to reduce pollutant emissions from vehicles with diesel engines and
the SCR catalyst, a urea - AdBlue ®
solution is injected into the exhaust system.
For vehicles with the AdBlue ®
injection system there is a note on the inside of
the fuel filler flap referring to the location of the AdBlue ®
filler neck and the
AdBlue ®
- minimum replenishment amount, that is required by a low AdBlue ®
-
level.
AdBlue ®
standard
Only use AdBlue ®
that corresponds to the standard ISO 22241-1.
AdBlue ®
- consumption
The AdBlue ®
consumption amounts to around 0.8 - 1.2 l / 1000 km.
The AdBlue ®
consumption depends on driving style, the operating tempera-
ture of the system and on the weather conditions.
For information on storing AdBlue ®
▶ Keep AdBlue ®
only in original sealed containers and in a safe place.
▶ Keep the container out of the reach of children.
▶ Do not expose the containers to direct sunlight or temperatures above 30° C.
Instructions for cleaning ▶ If any painted vehicle parts, clothing and carpets are splashed with AdBlue ®
wash the affected area with a damp cloth and plenty of cold water.
▶ Remove any dried AdBlue ®
with warm water and a sponge.

Depending on the engine the windshield washer fluid container
A
or
B
is lo-
cated in the engine compartment of the vehicle » Fig. 229.
The cleaning fluid is provided for the cleaning of the front and rear window as
well as the headlight.
The capacity of the reservoir
A
is about 3.1 litres or about 4.7 litres on vehicles
that have a headlight cleaning system.
The contents of the container
B
is approximately 3.7 litres.
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.
In Winter, the washing water should always be mixed with antifreeze 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. 
208General Maintenance

Winter time
The vehicle battery only has a proportion of the starting power in lower tem-
peratures. A discharged vehicle battery may already freeze at temperatures
just below 0 °C .
We therefore recommend that you have the battery checked and, if necessary,
recharged by a specialist garage before the start of the winter.
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 213 first.
A properly charged vehicle battery is essential for reliably starting the engine.A charging operation can be performed if the following conditions are satis-
fied.
The engine is turned off.
The ignition is switched off.
All consumers are turned off.
The bonnet is open.
“Fast charging” with high currents
›
Disconnect both battery cables (first of all “negative”, then “positive”).
›
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 on the
device.
›
After charging has been successful: Switch off the charger and remove the
mains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first “positive”, then “negative”).
Charging with low voltages
It is not necessary to disconnect the cables from the battery if you recharge
the vehicle battery, for example from a mini-charger.
Refer to the instructions of the charger manufacturer .
A charging current of 0.1 multiple of the total vehicle battery capacity (or low-
er) must be used until full charging is achieved.
The vent plugs of the vehicle battery should not be opened for charging.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 metal ob-
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
■
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 consumers and disconnect the negative
terminal 
.
■
“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
■
We therefore recommend that vehicle batteries be “rapidly charged” by a
specialist garage.
CAUTION
On vehicles with the START / STOP system or additional heating (auxiliary
heating), do not connect the pole terminal of the charger directly to the nega-
tive terminal of the vehicle battery but only to the engine earth » page 230.
Replacing
Read and observe
and on page 213 first.
The new vehicle battery must have the same capacity, voltage, current and thesame size as the original Battery. Suitable vehicle battery types can be pur-
chased from a specialist garage.
We recommend you have the battery replaced by a specialist garage.
