With the engine switched off, the vehicle battery is discharged by the connec-
ted consumers.
At low charge state of the vehicle battery, the power supply to the trailer (ac-
cessories) is interrupted.WARNING■ An improperly connected electrical installation of the trailer (accessories)
may result in an accident or serious injury from electrical shock.■
Do not make any adjustments to the electrical installation of the vehicle
and the trailer (accessories) - risk of an accident or serious injury from elec-
trical shock.
■
After the electrical connection between the vehicle and trailer (accessory)
the trailer / accessory lights should be checked for function.
■
Never use the securing eye to tow - The is a risk of an accident!
CAUTION
■ An improperly connected electrical installation of the trailer (accessories) can
lead to the inoperability of the vehicle electronics.■
The total power consumption of all the connected loads to the trailer power
supply must not exceed 350 watts, otherwise there is a risk of damage to the
electrical system of the vehicle.
Loading a trailer
Correct the tyre inflation pressure on the vehicle for “full load” » page 261.
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 load from slipping.
The distribution of the weight is very poor if your vehicle is unladen and the
trailer is laden. Nevertheless, maintain a particularly low speed if you cannot
avoid driving with this combination.WARNINGSliding cargo can significantly adversely affect stability and driving safety -
risk of accident!

Trailer operation
Driving speed
For safety reasons, do not drive with the trailer any faster than 100 km/h
(when the towing vehicle is a passenger car of category M1) or 80 km/h (when
the towing vehicle is a truck 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.
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
With frequent towing, the vehicle is excessively loaded so this must also be
checked between service intervals.Anti-theft alarm system
The alarm is triggered if, with a vehicle with activated anti-theft alarm (herein-
after only warning system), the electrical connection to the trailer (accessory)
is interrupted.
Always switch off the anti-theft alarm system before a trailer (accessory) is
coupled or uncoupled » page 55.
Conditions for including a trailer (accessory) in the anti-theft alarm system. The vehicle is factory-fitted with an anti-theft alarm system and a towing
device.
The trailer (accessory) is electrically connected to the towing vehicle by
means of the trailer socket.
The electrical system of the vehicle and trailer (accessory) is functional.
The vehicle is locked and the anti-theft alarm system is activated.
The trailer (accessory) is not equipped with LED taillights.239Towing device and trailer

WARNING■No changes may be made to airbag system components, the front bump-
er and the bodywork.■
Any work on the airbag system including the installation and removal of
system components due to other repair work (e.g. removal of the steering
wheel) must only be carried out by a specialist garage.
■
Do not manipulate individual parts of the airbag system, as this might re-
sult in the airbag being deployed.
■
If the airbag has been deployed, the airbag system must be replaced.
WARNINGThe airbag system operates using pressure sensors located in the front
doors. For this reason, no adjustments may be carried out to the doors or
door panels (e.g. installation of additional loudspeakers). Resulting damage
can impair the functioning of the airbag system -There is a risk of accidents
and fatal injuries! The following guidelines must therefore be observed.■
Any work on the front doors and their door panels must be carried out by
a specialist garage.
■
Never drive the vehicle with the inner door panels removed or with open-
ings in the panelling.

The service interval display in the display of the instrument cluster will remind
you to carry out every service stipulated by the manufacturer at the right time
in order to prevent you from forgetting any » page 48.
The completion of services can be verified through the printed verification
from the digital service schedule and the respective receipts.
The specified service intervals are tailored to normal operating conditions.
In the case of aggravated operating conditions, it will be necessary to have
some service work carried out before the date of the next regular service or
between the specified service intervals. This applies mainly to the cleaning or
the replacement of the air filter insert in regions with heavy dust pollution as
well as checking and replacing the toothed belt, but also to vehicles with die-
sel particle filters, which can put greater strain on the engine oil.
The following is taken to mean aggravated operating conditions:
▶ Fuel containing sulphur.
▶ Frequent short trips.
▶ Longer periods of engine idling (e.g. taxis).
▶ Operation in areas with heavy dust pollution.
▶ Frequent trailer operation.
▶ Predominantly stop-and-go traffic as is e.g. often the case in city driving.
▶ Operation predominantly during winter.
You will be told at the specialist garage whether the operating conditions of
your vehicle may make it necessary for service work to be carried out between
the normal service intervals.
Different service charges may apply according to the particular scope of work
required, the vehicle type and specification, and your vehicle’s condition.
Note
■ The customer is responsible for covering the cost of all services including
changing or replenishing the oil, even during the warranty period, unless sta-
ted otherwise in the ŠKODA AUTO warranty terms or other agreements.■
You will be informed about the service checks and actions at each service by
the specialist garage.

Overview of service intervalsFig. 283
Vehicle data: Service Interval
The service interval prescribed by the manufacturer is indicated on the vehicle
data » Fig. 283 . The vehicle data is affixed in the instructions and under the
floor covering in the luggage compartment.
One of the following service intervals applies for your vehicle. ▶ Fixed service interval QI1.
▶ Fixed service interval QI2.
▶ Fixed service interval QI3.
▶ Fixed service interval QI4.
▶ Variable service interval QI6.
In order to operate a vehicle with a variable service interval, it must only be
filled and topped up with the prescribed engine oil.
If this engine oil is not available, the oil change is subject to a fixed service in-
terval. In this case, the vehicle must be changed to the fixed service interval.
Note

WARNINGThe brake fluid must always be changed after the first 3 years and then ev-
ery 2 years. Longer intervals between changing the brake fluid can cause
vapour bubbles to form in the brake system when braking sharply. This can
impair the efficiency of the brakes –There is an risk of accident!
Note
For diesel operation with a high sulphur content, an oil change service must be
carried out every 7 500 km. Ask your specialist garage for information on the
countries where diesel fuel has a high sulphur content.
Variable service interval QI6
The oil change service intervals depend on the intensity at which the vehicle is
driven and the local conditions in which the vehicle is used. For example, your
vehicle is subjected to different demands when driven over short distances
than when driven over long distances. The intervals are therefore variable.

CAUTION■Never drive until the fuel tank is completely empty! 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 you would like to operate your vehicle in a country other than the one for
which it was intended, please talk to a ŠKODA Partner. They will tell you
whether the fuel specified by the manufacturer is offered in that country
and/or whether the manufacturer will sanction operating the vehicle with an-
other fuel.

The vehicle can only operate with unleaded petrol that meets standard EN
228 1)
, and contains maximum 10% bioethanol (E10).
Prescribed fuel 95 / min. 92 and 93 RON / ROZ
We recommend using petrol 95 ROZ.
Optionally, the petrol 92 or. 93 ROZ can be used (slight power loss, a slightly
increased fuel consumption).
In an emergency petrol 91 ROZ can be used (slight power loss, slightly in-
creased fuel consumption) »
.
Specified petrol is unleaded, min. 95 RON / ROZ
Use min. 95 ROZ petrol.
In an emergency , 91 . 92 or 93 ROZ petrol can be used (slight loss of power,
slightly increased fuel consumption) »
.
Prescribed petrol 98/(95) RON / ROZ
We recommend using petrol 98 ROZ.
Optionally, petrol 95 ROZ can be used (slight power loss, a slightly increased
fuel consumption).
In an emergency , 91 . 92 or 93 ROZ petrol can be used (slight loss of power,
slightly increased fuel consumption) »
.
CAUTION
The following instructions must be observed, otherwise there is a risk of dam-
age to the engine and to the exhaust system.■
When petrol with a lower than the prescribed octane is used, only continue
driving at mid-range engine speeds and with minimal strain on the engine. Re-
fuel using petrol of the prescribed octane number as soon as possible.
■
Lower than 91 octane petrol should not be used, even in an emergency!
■
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.
CAUTIONPetrol additions (additives)■Unleaded petrol complying with the EN 228 standard 1 )
meets all the condi-
tions for problem-free engine operation. We therefore do not recommend mix-
ing fuel additives into the petrol - risk of engine damage or damage to the ex-
haust system.■
The following additives may not be used - risk of engine damage or damage
to the exhaust system! ■ Additives with metal components (metallic additives), in particular with
manganese and iron content.
■ Fuels with metallic content (e.g. LRP - lead replacement petrol).
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 ROZ in does not result
in either a noticeable increase in power nor lower fuel consumption in vehicles
for which unleaded petrol 95/min 92 or 93 ROZ is specified.
■
On vehicles using the prescribed unleaded petrol of min. 95 ROZ, the use of
petrol with a higher octane number than 95 ROZ can lead to an increase in
power and reduction in fuel consumption.
Diesel fuel
Read and observe
and on page 248 first.
The correct grades of fuel for your vehicle are stated on a sticker affixed to theinside of the fuel filler flap » Fig. 285 on page 248 .

conditions for a smooth running engine. Therefore, we recommend that you do
not add any fuel additives to the diesel - - there is a risk of engine damage or
damage to the exhaust system.
Refuel CNG (compressed natural gas)
Fig. 288
Natural gas filler tubes
Read and observe
and on page 248 first.
Refuel with natural gas under the following conditions. The vehicle is unlocked.
The engine and the ignition are switched off.
The auxiliary heating and ventilation is switched off » page 109.
Natural gas refuelling may vary from station to station. If refuelling with natu-
ral gas at a station is unfamiliar to you, get someone to instruct you or allow
the fuelling operation to be carried out by the station staff.
Refuelling operation
›
Open the fuel filler flap.
› Remove cap A
» Fig. 288 in the direction of the arrow and insert connector
for the refuelling system into filler neck B.
The fuel tank is full when the compressor of the refuelling system automati-
cally switches off.›
Check that sealing ring
C
» Fig. 288 has remained inserted in filler neck
B
. If
the sealing ring has slipped on the connector, reinsert it into the filler neck.
›
Insert cap
A
into the filler neck and close the fuel filler flap until it locks into
place.
The natural gas refuelling systems have an overfill protection relating to the
outdoor temperature. At very high outside temperatures, it may happen that
the gas tank may not be fully refuelled.
If the vehicle is parked directly after a refuelling operation, on restart the
pointer of the gas gauge may not show exactly the same level as immediately
after the filling process. This is not a leak in the system, but a reduction in
pressure due to the cooling of the gas in the gas tank after refuelling.
The maximum lifetime of the gas tank is 20 years.
The capacity of the natural gas fuel tank is approximately 15 kg.
WARNING■
Natural gas is highly explosive and highly flammable.■When refuelling, never get into the vehicle. If you have to get into your
vehicle in exceptional cases, touch a metal surface before you touch the
filling coupling again. Otherwise, electrostatic discharging may occur -
There is a risk of fire!
Note
During the filling process sounds are heard which are harmless. If you are un-
sure which service station staff to use, ask the petrol station staff.251Inspecting and replenishing

Automatic switching from natural gas to petrol operation - Automatic switch-
ing from natural gas to petrol operation takes place in the following situations
(examples). ▶ With an empty gas tank or not enough pressure in the tank.
▶ After refuelling with natural gas.
▶ At very low surrounding temperatures.
To ensure the correct functioning of the fuel system, every 6 months the fuel tank for petrol should be run down until the warning light  comes on.
Gas leak
If a gas leak is suspected (noticeable odour), proceed as follows. ▶ Stop the vehicle.
▶ Switch off the ignition.
▶ Extinguish cigarettes, switch off spark-producing or incendiary items and re-
move them from the vehicle.
▶ Open the doors and the boot lid to ventilate the vehicle sufficiently.
▶ Do not continue to drive if the odour persists.
▶ If it is not possible to leave an enclosed area with a vehicle with a gas leak
(e.g. in a tunnel, underpass, garage, ferry, etc.), call the emergency services
immediately.
Seek help from a specialist garage to correct the gas system fault.
In a traffic accident
If a gas leak is suspected in a traffic accident, proceed as follows.
▶ Switch off the ignition.
▶ Extinguish cigarettes, switch off spark-producing or incendiary items and re-
move them from the vehicle.
▶ Have all the occupants get out.
▶ Keep all persons away from the vehicle. We recommend standing at least 10
metres from the vehicle.
▶ Inform the emergency services that it is a natural gas vehicle.
Regular gas system checks
Regular gas system checks must be carried out in a specialist workshop on
natural gas-powered vehicles. The vehicle owner is responsible for ensuring
tests are conducted properly.
Every 2 years ▶ Check the filler cap.
▶ Check the condition of fuel filler tubes and the sealing ring in the fuel filler
tubes, and clean the sealing ring if necessary.
▶ Check the gas system for leaks and carry out an examination of gas contain-
ers.
Every 20 years ▶ Replace the gas tank.WARNING■ Do not underestimate the smell of gas in the car or when refuelling - risk
of fire, explosion and injury.■
The natural gas tanks in the vehicle must not be exposed to unwanted
heat sources.
