Power supply of the trailer / accessory power system
In the electrical connection between the vehicle and trailer (accessory), the
trailer (accessories) is supplied with power from the vehicle (with ignition
switched on and off).
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.
■

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 277.
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!1)

Towing a trailer
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. 254Driving

WARNING■No changes may be made to parts of the airbag system, the front bumper
and the body.■
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 is triggered, the airbag system must be exchanged.
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). The resulting
damage can negatively affect the function of the airbag system - there is a
risk of accidents and fatal injuries! The following guidelines must be ob-
served.■
Any work on the front doors and their door panels must be carried out by
a specialist garage.
■
Never drive with removed inner door panels or openings in the panels.

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 them » page 49.
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 difficult operating conditions, it is necessary to have some serv-
ice work performed before the date of the next service or between the speci-
fied 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 diesel particle filters,
which can put greater strain on the engine oil.
The following is understood under difficult 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 often the case in city driving, for ex-
ample.
▶ 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 from the particular scope of work required,
depending on the vehicle type and equipment and the status of your vehicle.
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 current service scopes for the particular serv-
ice work by the specialist garage.

Overview of service intervalsFig. 312
Vehicle data: Service interval
The service interval is predefined by the manufacturer indicated on the vehicle
data carrier » Fig. 312. The vehicle data carrier is affixed in the instructions and
under the floor covering in the luggage compartment.
One of the following service intervals applies to 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 flexible service interval, it is necessary
that only the prescribed engine oil is used.
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 on sharp braking. This can im-
pair the efficiency of the brakes – risk of accident!
Note
For diesel operation with a high sulphur content, the oil must be changed ev-
ery 7,500 km. Ask your specialist garage for information on the countries
where diesel fuel has a high sulphur content.
Flexible 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 flexible.
