WARNINGNever exceed the maximum permissible axle and draw bar load or the per-
missible weight of the trailer - risk of accident!
Towing a trailer
Driving speed
For reasons of safety do not drive more than 100 km / h when the towing vehi-
cle is a passenger car of category M1.
For reasons of safety do not drive more than 80 km / h when the towing vehi-
cle is a lorry of category N1.
Immediately reduce your speed as soon as even the slightest swaying of the
trailer is detected. Never attempt to stop the trailer from “swaying” by acceler-
ating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply
the brakes gently at first, then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking. 188Driving

On downhill sections shift down a gear in good time to also use the engine as
a brake.WARNINGAlways drive particularly carefully with the trailer.
CAUTION
If you tow a trailer frequently, you should also have your vehicle inspected be-
tween service intervals.
Anti-theft alarm system
If the vehicle is locked, the alarm is activated when the electrical connection to
the trailer is interrupted.
Always switch off the anti-theft alarm system before a trailer is coupled or un-
coupled » page 57 .
Conditions for including a trailer in the anti-theft alarm system. The vehicle is factory-fitted with an anti-theft alarm system and towing
device.
The trailer is electrically connected to the towing vehicle via the trailer
socket.
The electrical system of the vehicle and trailer is functional.
The vehicle is locked and the anti-theft alarm system is activated.
CAUTION
For technical reasons, trailers with rear LED lights cannot be connected to the
anti-theft alarm system.189Hitch and trailer

Regularly remove salt and brake abrasion, otherwise the rim material will be
corroded.
Light alloy wheel trims
After washing thoroughly and treat the wheel rims with a protective product
for light alloy wheels.
For the treatment of wheel rims do not use products which may cause damage
to the paint on the rims.
CAUTION
■ Damage to the paint layer on the wheel rims must be touched up immediate-
ly.■
Severe 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.
Under-body protection
Read and observe
and on page 195 first.
The underside of your vehicle is already permanently protected by the factory
against chemical and mechanical influences.
It is not possible to guarantee that the protective coating will not suffer any
damage as the vehicle is driven.
We recommend having the protective coating 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!Wiper blades
Read and observe
and on page 195 first.
Clean the wiper blades regularly with a glass cleaner. The wiper blades should
be cleaned with a sponge or cloth if they are heavily soiled by insect residues,
for example.
The wiper blades can become soiled with wax residues after washing in auto-
matic vehicle wash systems for example.

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.

Incorrect refuelling guard on vehicles with diesel engines
The fuel filler tube on vehicles with diesel engines has been fitted with a in-
correct refuelling guard » Fig. 225. This guard means it is only possible to re-
fuel 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.
WARNINGInstructions for filling the reserve canister■Never fill the reserve can inside the vehicle.■
Never place the reserve can on the vehicle.
■
Always place the reserve can on the floor.
■
We do not recommend carrying any fuel canisters in your vehicle for safe-
ty reasons. in the event of an accident, these canisters can become dam-
aged and fuel may escape – risk of fire!
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. Not continue refuelling.■
Be careful when filling diesel fuel from the spare canister and then do this
slowly and cautiously – danger of contaminating 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
fuelling protection should be removed by a specialist company.
Note
The fuel tank has a capacity of about 66 litres, including a reserve of approx.
6 litres .Lead-free petrol
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 unleaded petrol in compliance with the
EN 228 1)
standard.
All petrol engines can be operated using petrol that contains at most 10% bio-
ethanol (E10).
Unleaded petrol 95 / min. 92 and 93 RON / ROZ
We recommend using unleaded fuel with an octane rating of 95 RON. Unlea-
ded petrol with the octane ratings 92 or 93 RON can also be used, but may re-
sult in a slight loss in performance and slightly increased fuel consumption.
Unleaded petrol min. 95 RON / ROZ
Use unleaded fuel with the octane rating 95 RON or higher.
In an emergency petrol with the octane ratings 91, 92 and/or 93 RON can also
be used, but may result in a slight loss in performance and slightly increased
fuel consumption. Continue driving at medium engine speeds and minimum
engine load »
.
Refuel using petrol of the prescribed octane number as soon as possible.
Unleaded petrol 98/(95) RON / ROZ
We recommend using unleaded fuel with an octane rating of 98 RON or higher.
Unleaded petrol 95 RON can also be used but this results in a slight loss in per-
formance and slightly increased fuel consumption.
In an emergency petrol with the octane ratings 91, 92 and/or 93 RON can also
be used, but may result in a slight loss in performance and slightly increased
fuel consumption. Continue driving at medium engine speeds and minimum
engine load »

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.
202General Maintenance

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.
