›Place the filler cap onto the fuel filler neck and turn it clockwise until it securely
engages.›
Close the fuel filler flap until it clicks into place.
Check that the fuel filler flap is closed properly.
Incorrect refuelling guard on vehicles with diesel enginesThe fuel filler tube on vehicles with diesel engines has been fitted with a incor-rect refuelling guard » Fig. 179. This guard means it is only possible to refuel with
the diesel pump nozzle.
If the diesel pump nozzle does not sit directly in the fuel filler tube, move it to and fro with slight pressure to insert it correctly.
CAUTION
■ 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. Do not continue filling the fuel tank otherwise the expansion volume is filled up.■
Be careful when filling diesel fuel from the spare canister – danger of contami-
nating the body.
■
The diameter of the diesel pump nozzle can be identical to that of the petrol
pump nozzle in some countries. When driving in these countries, the incorrect fu-
elling protection should be removed by a specialist company.
Note
The fuel tank has a capacity of about 50 litres, containing a reserve of approx.
7 litres .
Unleaded petrol
First read and observe the introductory information and safety warn-
ings
on page 212.
Your vehicle can only be operated with unleaded petrol in compliance with the
EN 228 1)
standard.
All petrol engines can be operated using petrol that contains at most 10% bioe-
thanol (E10).
Required fuel - unleaded petrol 95/91 or 92 or 93 RON
Use unleaded fuel with the octane rating 95 RON. Unleaded petrol with the oc-
tane ratings 91, 92 or 93 RON can also be used, but may result in a slight loss in
performance.
Prescribed fuel – unleaded petrol min. 95 RON
Use unleaded fuel with the octane rating 95 RON or higher.
In case of necessity, you can refuel with petrol with the octane ratings 91, 92 or
93 RON, if petrol with the octane rating 95 RON is not available »
.
Prescribed fuel – unleaded petrol 98/(95) RON Use unleaded fuel with the octane rating 98 RON or higher. Unleaded petrol
95 RON can also be used but results in a slight loss in performance.
In case of necessity, you can refuel with petrol with the octane ratings 91, 92 or
93 RON, if unleaded fuel with octane rating 98 RON or 95 RON is not availa-
ble »
.
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 addi-
tives are used. This can result in considerable damage to parts of the engine or
the exhaust system.
CAUTION
■ Even filling the tank with leaded petrol that does not meet the standards once
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 used by mistake, do not start the engine or
switch on the ignition! Extensive damage to engine parts can occur! We recom-
mend that you have the fuel system cleaned by a specialist garage. 
1)
In Germany also DIN 51626-1 or E10 for unleaded petrol with octane number 91 or 95 or DIN 51626-2
or E5 for unleaded petrol with octane number 95 and 98.
213Inspecting and replenishing

CAUTION■If, in an emergency, the vehicle has to be refuelled with petrol of a lower octane
number than the one prescribed, the journey must only be continued at medium
engine speeds and a low engine load. Driving at high engine revs or a high engine
load can severely damage the engine! Refuel using petrol of the prescribed oc-
tane number as soon as possible.■
Engine parts can be damaged if petrol with a lower octane number than the one
prescribed is used.
■
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 and iron content. LRP(lead replacement petrol) fuels with metal-
lic components may not be used. There is a risk of causing considerable damage
to parts of the engine or exhaust system!■
Fuels with metallic content may not be used. There is a risk of causing consider-
able damage to parts of the engine or exhaust system!
Note
■ Unleaded petrol that has a higher octane number than that required by the en-
gine can be used without limitations.■
On vehicles with prescribed unleaded petrol 95/91, 92 or 93 RON, the use of
petrol with a higher octane number than 95 RON does not result in a noticeable
power increase or a lower fuel consumption.
■
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of petrol
with a higher octane number than 95 RON can increase the power and reduce
fuel consumption.

Diesel fuel
First read and observe the introductory information and safety warn-ings
on page 212.
Your vehicle can only be operated with diesel fuel that meets the EN 5901)
stand-
ard.
All diesel engines can be operated using diesel fuel with at most 7% biodiesel
(B7) 2)
.
On the Indian market, your vehicle will only be able to run on diesel fuel compli-
ant with standard IS 1460/Bharat IV. If diesel fuel which complies with this stand-
ard 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 fuelsavailable have a different temperature characteristic. The ŠKODA Partners and
filling stations in the relevant country will be able to provide you with information
regarding the diesel fuels available.
Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures operation of a vehicle using diesel fuel down to an environmental temperature of -24 ℃.
Diesel fuel additives
Additives, so-called “flow improvers ” (petrol and similar agents) should not be mixed with the diesel fuel. This can cause serious damage to engine or exhaust
system parts. 

217Inspecting and replenishing

Checking the battery electrolyte levelFig. 188
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 224.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 188, the electrolyte level can be determined by looking at the
change in colour.
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
› Black colour – electrolyte level is correct.
› Colourless or light yellow colour – electrolyte level too low, the battery must be
replaced.
Vehicles with a START-STOP system are fitted with a battery control unit for checking the energy level for the recurring engine start.
We recommend that you have the acid level checked regularly by a specialist ga-
rage, especially in the following cases.
› High external temperatures.
› Longer day trips.
› After each charge.
Winter time
The vehicle battery only has a proportion of the starting power in lower tempera-
tures. A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C .
We therefore recommend that you have the battery checked and, if necessary, re-
charged by a specialist garage before the start of the winter.
CAUTIONFor technical reasons, on vehicles with the description “AGM”, the electrolyte lev- el cannot be checked.
Note
The battery acid level is also checked regularly by a specialist garage as part of
the inspection service.
Charging
First read and observe the introductory information and safety warn-ings
on page 224.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
›
Only when performing a “quick-charge”, disconnect both battery cables (first of
all “negative”, then “positive”).
›
Attach the terminal clamps of the charger to the battery terminals (red = “posi- tive”, 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 themains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first of all “positive”, then “negative”).
It is not necessary to disconnect the cables of the battery if you recharge the ve- hicle battery using low amperages (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 lower) must be used until full charging is achieved.
It is necessary to disconnect both cables before charging the battery with high
amperages, so-called “ quick-charging”.
The vent plugs of the vehicle battery should not be opened for charging. 
226General Maintenance

›The wheels of one axle are loaded more heavily (e.g. when towing a trailer or
when driving uphill or downhill).
› Snow chains are mounted.
› The spare wheel is mounted.
› One wheel per axle was changed.
For vehicles with Infotainment 1)
it can be determined which tyres should be
checked » Manual Infotainment , chapter Vehicle settings (key CAR) .WARNING■
When the warning light  illuminates, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Stop the vehicle as soon as
possible and inspect the tyres and their inflation pressure.■
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the  may light up after a delay, or not at all.
CAUTION
■
The tyre control display does therefore not replace the regular tyre inflation
pressure control, as the system cannot detect an even loss of pressure.■
The system cannot warn in case of very rapid tyre inflation pressure loss, e.g. in
case of sudden tyre damage. In this case carefully bring the vehicle to a standstill
without sudden steering movements or sharp braking.
■
To ensure a proper functioning of the tyre control display, it is necessary to re-
peat the basic setting every 10000 km or once a year.

240WARNING■ If you are in flowing traffic, switch on the hazard warning light system and
set up the warning triangle at the prescribed distance! The national legal re-
quirements must be observed.■
Park the vehicle as far away as possible from the flow of traffic. Park on as
flat and firm a surface as possible.
■
If the vehicle is subsequently fitted with tyres which are different from
those it was fitted with at the works, follow these guidelines » page 230, New
tyres .
WARNINGObserve the following instructions for lifting the vehicle.■If the wheel has to be changed on a slope, first of all block the opposite
wheel with a stone or similar object to prevent the vehicle from unexpectedly
rolling away.■
Secure the base plate of the lifting jack with suitable means to prevent pos-
sible moving. A soft and slippery ground under the base plate may move the lifting jack, causing the vehicle to fall down. It is therefore always necessary to
place the lifting jack on a solid surface or use a wide and stable base. Use a non-slip base (e.g. a rubber foot mat) if the surface is smooth, such as cobbled
stones, tiled floor, etc.
■
Only attach the lifting jack to the attachment points provided for this pur-
pose.
■
Always raise the vehicle with the doors closed.
■
Never position any body parts, such as arms or legs under the vehicle, while
the vehicle is raised with a lifting jack.
■
Never start the engine with the vehicle sitting on the raised jack – risk of in-
jury.
CAUTION
■ The tightening torque specified for the wheel bolts for steel and light alloy
wheels is 120 Nm.■
If the wheel bolts are fastened too tightly, this can cause damage to the anti-
theft wheel bolt or the adapter.
Note
The national legal requirements must be observed when changing a wheel.
