Passive Safety

The following guidelines must be observed when using a child safety seat in
which the child is seated with its back facing the direction of travel on the front
passenger seat.
›
Switch off the front passenger airbag
» page 133, Deactivating airbags .
› Slide the front passenger seat all the way back.
› Move the front passenger seat backrest into the vertical position.
› Set the height-adjustable front passenger seat as high up as possible.
› Adjust the seat belt for the front passenger seat so that it is as high as possible
(not suitable for a child seat fastened with the
ISOFIX system).
› Place and fasten the child seat on the seat and the child in the child seat ac-
cording to the specifications in the manufacturer's user manual of the child
seat . WARNING
■ It is essential to always switch off the front passenger airbag when attach-
ing a child safety seat to the front passenger seat where the child is seated
with its back facing in direction of travel » page 133 , Deactivating airbags.
■ Never use a child safety seat in which the child is seated with its back facing
the direction of travel on the front passenger seat if the airbag is switched on.
This child safety seat is positioned in the deployment area of the front pas-
senger airbag. The airbag may cause the child severe, or even fatal injuries, in
the event of it being deployed.
■ This is also clearly stated on the sticker which is located on the B column on
the front passenger side » Fig. 121. The sticker is visible upon opening the
front passenger door. For some countries, the sticker is also affixed to the sun
visor of the front passenger.
■ If a child safety seat in which the child faces in the direction of travel is used
on the front passenger seat, the front passenger seat must be moved back
and to the top fully. Move the backrest into the vertical position. ■ The front passenger airbag must be reactivated as soon as you no longer
use a child seat on the front passenger seat. Ð Child safety and side airbag
Fig. 122
Incorrect seated position of a child who is not properly secured -
risk from the side airbag/Child properly protected by safety seat
First read and observe the introductory information and safety warn-
ings on page 135.
The child must not be positioned in the deployment area of the side air-
bag » Fig. 122 - . There must be sufficient room between the child and the de-
ployment area of the side airbag so that the airbag can provide as much protec-
tion as possible » Fig. 122 - . WARNING
■ Children must never be seated with their head in the deployment area of
the side airbag - risk of injury!
■ Do not place any objects within the deployment area of the side airbags -
risk of injury! Ð Classification of child seats
First read and observe the introductory information and safety warn-
ings on page 135.
Child safety seats are classified in 5 groups:
Group Weight of the child Approximate age
0 0-10 kg up to 9 months
0+ up to 13 kg up to 18 months£ ä

Towing a trailer
Towing a trailer
Technical requirements
If your vehicle has already been factory-fitted with a towing device or is fitted
with a towing device from ŠKODA Original Accessories, then it meets all of the
technical requirements and national legal provisions for towing a trailer.
On vehicles with a towing device, the ball rod is detachable and is stowed togeth-
er with separate operating instructions in the spare wheel well or in the compart-
ment for the spare wheel within the boot » page 179, Vehicle tool kit .
Your vehicle is fitted with a 13-pin power socket for the electrical connection be-
tween the vehicle and trailer. If the trailer that is to be towed has a 7-pin connec-
tor, you can use a suitable adapter from
ŠKODA Original Accessories.
If a towing device is retrofitted, it must be completed in accordance with the
manufacturer's specifications. Note
If you have any questions, please contact a ŠKODA Service Partner. ÐLoading a trailer
Loading a trailer
The vehicle/trailer combination must be balanced, whereby the maximum permis-
sible drawbar load must be utilised. If the drawbar load is too low, it jeopardises
the performance of the vehicle/trailer combination.
Distribution of the load
Distribute the load in the trailer in such a way that heavy items are located as
close to the axle as possible. Secure the items from slipping.
The distribution of the weight is very poor if your vehicle is unladen and the trail-
er is laden. Maintain a particularly low speed if you cannot avoid driving with this
combination. Tyre pressure
Correct the tyre inflation pressure on your vehicle for a

“full load” » page 171,
Service life of tyres.
Trailer load
The permissible trailer load must not be exceeded under any circumstan-
ces » page 197, Technical data .
The trailer loads specified apply only to altitudes up to 1 000 metres above mean
sea level. As the engine output drops at an increasing altitude due to the declin-
ing air pressure and therefore the climbing ability is also reduced, this means that
the maximum permissible towed weight must be reduced by 10 % for every fur-
ther increase of 1 000 m in height. The towed weight comprises the actual weight
of the (loaded) towing vehicle and the (loaded) trailer. Always drive particularly
carefully with the trailer.
The trailer and drawbar load information on the type plate of the towing device
are merely test data for the towing device The vehicle-specific values are detailed
in the vehicle documents. WARNING
■ If the maximum permissible axle and drawbar load and the maximum per-
missible total or towed weight of the vehicle and the trailer are exceeded this
can cause accidents and serious injuries.
■ Slipping loads can significantly affect the stability and safety of the vehicle/
trailer combination, causing accidents and serious injuries. Ð Towing a trailer
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see the
traffic behind the trailer with the standard rear-view mirrors. The national legal
requirements must be observed.
Headlights
The headlight settings must be checked before starting a journey with a coupled
trailer. If necessary, adjust the settings with the headlight beam adjust-
ment » page 44 , Headlight beam adjustment .
Driving speed
For safety reasons, do not drive faster than the maximum permissible speed indi-
cated on the trailer. £

Towing a trailer

Diesel fuel
First read and observe the introductory information and safety warn-
ings on page 155.
Your vehicle can only be operated with
diesel fuel, which complies with the
standard EN
590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in
Austria, GOST R 52368-2005/EN 590:2004 in Russia).
Operation in winter - Winter-grade diesel fuel
In the winter, only use diesel fuel, which complies with the standard EN 590
(standard DIN 51628 in Germany, standard ÖNORM C 1590 in Austria,
GOST R 52368-2005/EN 590:2004 in Russia). “Winter-grade diesel fuel” 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. The ŠKODA Service Partners
and filling stations in the relevant country will be able to provide you with infor-
mation 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 -25 °C.
Fuel additives
Fuel additives, so-called “flow improvers” (petrol and similar products) must not
be added to the diesel fuel. CAUTION
■ Just filling the tank once with diesel fuel that does not comply with the stand-
ard, can cause severe damage to parts of the engine, the fuel and exhaust sys-
tem!
■ If a different fuel other than diesel fuel, which complies to the above mentioned
standards (e.g. petrol) is used by mistake do not start the engine or switch on the
ignition! Extensive damage to engine parts can occur! We recommend that the
fuel system is cleaned by a

ŠKODA Service Partner.
■ Water which has collected in the fuel filter can cause engine faults.
■ Your vehicle is not adapted for use of 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. Ð

reason, it is essential to comply with the warning instructions stated below and
with the general applicable rules of safety. The vehicle's engine compartment is
a hazardous area . WARNING
■ Never open the bonnet if you can see steam or coolant flowing out of the
engine compartment - risk of scalding! Wait until the steam or coolant has
stopped escaping.
■ Turn off the engine and withdraw the ignition key.
■ If the vehicle is fitted with a manual gearbox, move the gearshift lever into
Neutral, or if the vehicle is fitted with an automatic gearbox, move the selec-
tor lever into position P .
■ Firmly apply the handbrake.
■ Allow the engine to cool.
■ For safety reasons, the bonnet must always be properly closed when driving.
This is why after closing the bonnet, the lock must always be checked to en-
sure it has engaged properly. £
158 General Maintenance

WARNING (Continued)
■ If you notice that the lock is not properly engaged while driving, stop the ve-
hicle immediately and close the bonnet - risk of an accident!
■ Keep children clear of the engine compartment.
■ Do not touch any hot engine parts - risk of burns!
■ Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite!
■ Avoid short circuits in the electrical system - particularly on the vehicle's
battery.
■ Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running! ■ Never open the end cover of the coolant expansion reservoir while the en-
gine is still warm. The cooling system is pressurized!
■ When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot cool-
ant.
■ Do not leave any items such as cloths or tools in the engine compartment.
■ If you wish to work under the vehicle, you must secure the vehicle from roll-
ing away and support it with suitable supporting blocks: the car jack is not
sufficient for this - risk of injury!
■ If any inspection work has to be carried out when the engine is running,
there is an additional risk from rotating parts (e.g. V-belt, alternator, radiator
fan) and the high-voltage ignition system. The following must also be ob-
served: ■Never touch the electric wiring on the ignition system.
■ Always make sure that no jewellery, loose clothing or long hair can get
caught in rotating engine parts - hazard! Always remove any jewellery, tie
back long hair and wear tight fitting clothing before completing any work.
■ Additionally, the following warning instructions must be observed if work
has to be carried out on the fuel or electrical system. ■Always disconnect the vehicle battery from the electrical system.
■ Do not smoke.
■ Never work near open flames.
■ Always have a functioning fire extinguisher nearby. CAUTION
■ Always top up using the correct specification of fluids. This may result in major
operating problems and also vehicle damage!
■ Never open the bonnet using the locking lever - danger of causing damage. For the sake of the environment
In view of the environmentally friendly disposal of fluids, the specials tools and
knowledge required for such work, we recommend that fluids are changed by a
Škoda
Service Partner as part of the inspection service. Note
■ If you have any questions regarding the fluids, visit a
ŠKODA Service Partner.
■ Fluids with the correct specifications can be purchased from ŠKODA Original Ac-
cessories. Ð

indicator
ä First read and observe the introductory information and safety warn-
ings on page 165.
We recommend you have the electrolyte level checked by a ŠKODA specialist ga-
rage from time to time, especially in the following cases.
› High outside temperatures.
› Long daily drives
› After each charge
» page 168.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 139, 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. Note
■ The battery electrolyte level is periodically checked by a ŠKODA Service Partner
as part of the Inspection Service. ■ For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked. ■ Vehicles with a START-STOP system are fitted with a battery control unit for
checking the energy level for the recurring engine start. Ð Operation in winter
First read and observe the introductory information and safety warn-
ings on page 165.
At low temperatures, the vehicle battery only has part of the initial power output
that it has at normal temperatures.
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, re-
charged by a ŠKODA Service Partner before the start of the winter.
