Kickdown function
First read and observe the introductory information and safety warn-ings
on page 129.
The kickdown function provides you with maximum acceleration power.
When the accelerator pedal is fully depressed, the kickdown function is activated
in the desired driving program. The gearbox shifts down to one or several gears in
line with the driving state and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has reached
its maximum revolutions for this gear range.
Note
The kickdown function is also available in the Eco » page 124 driving mode.
Dynamic shift programme
First read and observe the introductory information and safety warn-
ings
on page 129.
The control unit on the automatic gearbox continuously monitors the driving per-
formance and takes the selected driving mode into account » page 124. The dy-
namic shifting program is adapted to it.
Adopting a moderate style of driving will cause the control unit to select the
most economical driving programme. Shifting up into a higher gear as soon as
possible and shifting down as late as possible will have a favourable effect on
your fuel consumption.
If the control unit detects that sporty style of driving is active, the driving pro-
gramme is adapted to this style and gears are shifted down more quickly than in
the moderate style of driving.
Emergency programme
First read and observe the introductory information and safety warn-
ings
on page 129.
An emergency programme exists in the event of a fault in the system.
The gearbox operates in a corresponding emergency programme if there are
functional faults in the gearbox electronics.
A functional fault can have the following effect:
› The gearbox only shifts into certain gears;
› The reverse gear
R cannot be used,
› The manual shift programme is switched off in emergency mode.
Note
When the gearbox has switched to emergency mode, consult a ŠKODA Specialist
garage.
132Using the system

during the collision remains below the prescribed reference values specified in
the control unit, the airbags are not deployed although the vehicle may well suf-
fer severe damage to the bodywork as a consequence of the accident.
The following will be deployed in the event of a severe frontal collision: › driver’s front airbag;
› passenger’s front airbag;
› driver’s knee airbag.
The following will be deployed in the event of a severe side collision: › front side airbag on the side of the accident;
› rear side airbag on the side of the accident;
› head airbags on the side of the accident.
In the event of an accident in which the airbags are deployed:
› the interior lighting comes on (if the switch for the interior light is in the door
contact position),
› the hazard warning light is switched on;
› all the doors are unlocked;
› the fuel supply to the engine is interrupted.
Front airbags

Driver airbag in the steering wheel/front passenger airbag in the
dashboard
Fig. 132
Safe distance to steering wheel/inflated airbags
In the event of a severe frontal collision, the front airbag system offers additional
protection for the head and chest area of the driver and front passenger.
The front airbag for the driver is housed in the steering wheel » Fig. 131 – 
.
The front airbag for the front seat passenger is located in the dash panel above
the stowage compartment 
– » Fig. 131 .
When the airbags are deployed, they inflate in front of the driver and front pas-
senger » Fig. 132 - 
. The forward movement of the driver and of the front pas-
senger is cushioned when they make contact with the fully inflated airbag and
the risk of injury to head and chest is thus reduced.
The airbag allows the gas to flow out of the inflated airbag in a controlled manner(depending on the load of the particular car occupant) in order to cushion head
and chest areas. The airbag then deflates subsequently to such an extent, after
an accident, to again provide a clear view forward.
WARNING■ For the driver and front passenger, it is important to maintain a distance of
at least 25 cm to the steering wheel or dashboard A » Fig. 132 . Not maintain-
ing this minimum distance will mean that the airbag system will not be able to
properly protect you – hazard! The front seats and the head restraints must always also be correctly adjusted to match the body size of the occupant.■
The airbag develops enormous forces when triggered, which can lead to in-
juries if the sitting position or seated position is not correct.
■
There must not by any further persons, animals or objects positioned be-
tween the front seated occupants and the deployment area of the airbag. 

Passenger protection system
Introductory information
The Passenger protection system helps you reduce the impact of a collision with a pedestrian.
The system is activated automatically in the event of a frontal collision with a pe-
destrian at speeds of 30-55 km/h. In the event of an impact, the rear section of
the bonnet is raised by approx. 55 mm thus creating a crumple zone above the
engine.
The system sensors are integrated in the front bumper.
The functional status of the system is indicated by the indicator light 
in the in-
strument cluster » page 19.
In some cases, the system may be activated even if the vehicle did not collide
with a pedestrian, e.g.:
› in a frontal collision with a lamppost, a street light, column, etc.;
› in a frontal collision with an animal;
› when driving over a mound of snow;
› when the suspension comes into contact with the road;
› when driving over pronounced corrugations perpendicular to the direction of
travel.
We recommend that any modifications and repairs to the front bumper or body-
work be carried out by a ŠKODA Partner. Further information » page 165.
WARNING■
Work or technical modifications on your vehicle, which have been carried out
unprofessionally, can cause operational faults – risk of accident!■
Do not attach the front number plate in the holder. Instead, screw it onto
the bumper in the area provided. The attached number plate holder impairs
the functioning of the sensors and thus the assessment made to determine
whether to activate the system or not.
NoteWhen disposing of the vehicle or parts of the Passenger protection system, it is
important to comply with national legal requirements. ŠKODA Partners are famili-
ar with these regulations and will be able to provide you with detailed informa-
tion.
Activating the system
Fig. 138
Raised bonnet
If the Passenger protection system was activated:
› the bonnet is raised
» Fig. 138 - 
;
› The indicator light

is lit in the instrument cluster.
The bonnet can only be raised after the system has been activated if it was not deformed previously.
WARNING■ After activation, the system no longer meets its protective function. Drive to
your nearest ŠKODA Partner immediately and adopting an appropriately cau-
tious style of driving, who will replace the system. Do not exceed 80 km/h.■
Adjust the height of the seat so that the raised bonnet does not block your
view ahead » Fig. 138 -  . Stop driving if the view ahead remains impaired
even at the highest seat position!

Rubber sealsFirst read and observe the introductory information and safety warn-
ings
on page 159.
The rubber seals on doors, door panels, and the sliding roof remain smoother and
last longer if the seals are treated regularly with a suitable rubber care product.
This helps to prevent leakages and premature wear of the seals. Rubber seals
which are well cared for also do not stick together in cold winter weather.

Door lock cylinders
First read and observe the introductory information and safety warn-
ings
on page 159.
Specific products must be used for de-icing door lock cylinders.
When washing your vehicle, ensure as little water as possible gets into the lock- ing cylinders.
Note
We recommend that suitable materials from ŠKODA Original Accessories are used for maintaining the door lock cylinders.
Wheels
First read and observe the introductory information and safety warn-
ings
on page 159.
Wheel rims
Also thoroughly wash the wheel rims when washing the vehicle on a regular ba- sis. Regularly remove salt and brake abrasion from the wheel rims otherwise the material will be affected. Damage to the paint layer on the wheel rims must be
touched up immediately.
Light alloy wheels
After washing thoroughly and treat the wheel rims with a protective product for
light alloy wheels. Products which cause abrasion must not be used to treat the
wheel rims.
WARNINGWater, ice and grit in the brake system can affect the braking efficiency – risk
of accident!
CAUTION
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.
Note
We recommend that any repairs to damaged paintwork are carried out by a
ŠKODA Partner.
Underbody protection
First read and observe the introductory information and safety warn-ings
on page 159.
The underside of your vehicle is protected for life against chemical and mechani-
cal influences.
As damage to the protective layer when driving cannot be ruled out completely,
we recommend that you inspect the protective layer on the underside of your ve- hicle and on the chassis at specific intervals – preferably at the beginning and end
of the winter.
ŠKODA Partners have suitable spray products and the necessary equipment
available, and are familiar with the instructions for use. We therefore recommend
that touch-up work or additional corrosion protection measures are carried out by
a ŠKODA Partner.
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 might ignite
– risk of fire!

Check that the fuel filler flap is closed properly.
Incorrect refuelling guard on vehicles with diesel engines The fuel filler tube on vehicles with diesel engines has been fitted with a incor-
rect refuelling guard » Fig. 145. 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.■
Before refuelling, switch off the auxiliary heating system (auxiliary heating and
ventilation).
■
Be careful when filling diesel fuel from the spare canister - danger of contami-
nating the body.
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 167.
Your vehicle can only be operated with unleaded fuel that complies with the
standard EN 228 (in Germany: standard DIN 51626-1 or E10 for unleaded fuel with
an octane rating of 95 RON and 91 RON or DIN 51626-2 or E5 for unleaded fuel
with the octane rating 95 RON and 98 RON).
Prescribed fuel – unleaded fuel 95/91 RON Use unleaded fuel with the octane rating 95 RON. Unleaded petrol 91 RON can al-
so be used but results in a slight loss in performance.
Prescribed fuel – unleaded petrol min. 95 RONUse unleaded fuel with the octane rating 95 RON.
In case of necessity, you can refuel with petrol with the octane rating 91 RON if
petrol with the octane rating 95 RON is not available.
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!
Unleaded petrol with higher octane number
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 RON, the use of petrol with a
higher octane number than 95 RON does not result in a noticeable power in-
crease 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.
Prescribed fuel – unleaded petrol 98/(95) RON
Use unleaded fuel with the octane rating 98 RON. 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 rating 91 RON of
unleaded fuel with octane rating 98 RON or 95 RON is not available.
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!
Fuel additives
Only use unleaded petrol, which complies with the standard EN 228 (in Germany:
standard DIN 51626-1 or E10 for unleaded fuel with an octane rating of 95 RON and 91 RON or DIN 51626-2 or E5 for unleaded fuel with an octane rating of
95 RON and 98 RON), as these meet all of the requirements for fault-free engine operation. We therefore recommend that no fuel additives are used.
CAUTION
■ All ŠKODA vehicles with petrol engines must only be operated with unleaded
petrol. Just filling the tank with leaded petrol once will damage the exhaust sys-
tem!■
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. 
168General Maintenance

■Engine parts can be damaged if petrol with a lower octane number than the one
prescribed is used.■
In no case may fuel additives with metal components be used, especially not
with manganese and iron content. Do not use any LRP fuels (lead replacement petrol) with metal parts - risk of serious damage to parts of the engine or exhaust
system!
■
Do not use any fuels with metal parts - risk of serious damage to parts of the
engine or exhaust system!
■
The use of unsuitable fuel additives can cause considerable damage to parts of
the engine or the exhaust system.

Diesel fuel
First read and observe the introductory information and safety warn-ings
on page 167.
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).
All diesel engines can be operated with diesel fuel with a maximum content of
7 % bio-fuel (B7), which complies with the standard DIN 52638 in Germany (in
Austria C 1590, in France EN 590).
Operation in winter – Winter-grade diesel fuel In the cold season, only use “winter-grade diesel fuel” which will still operateproperly 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 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 -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!■
Damage caused by using diesel fuel which does not comply with the standards
are excluded from the warranty.
■
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 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.
■
Comply with the proscribed oil change intervals.

WARNINGWhen working in the engine compartment, injuries, scolding, accident or fire
hazards may arise. For this reason, it is essential to comply with the warning
instructions stated below and with the general applicable rules of safety. The
engine compartment of your car is a hazardous area!■
Before beginning work in the engine compartment, please read the follow-
ing advice. ■ Turn off the engine and withdraw the ignition key.
■ Firmly apply the handbrake.
■ 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 se- lector lever into position P.
■ Allow the engine to cool.
■ 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.
■
While working in the engine compartment, please read the following advice.
■ Keep children clear of the engine compartment.
■ Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running!
■ Do not touch any hot engine parts – risk of burns!
■ The coolant additive and thus all of the coolant is harmful to your health.
■ Avoid contact with the coolant.
■ Coolant vapours are harmful to health.
■ 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 coolant. ■ If any coolant splashes into your eyes, immediately rinse out your eyes
with clear water and contact a doctor as soon as possible.
■ Always safely store the coolant additive in its original container out of the
reach of children – risk of poisoning!
■ If coolant is swallowed - consult a doctor immediately.
■ Do not leave any items such as cloths or tools in the engine compartment.
■ Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite!
WARNING (Continued)■ Whenever working in the engine compartment while the engine is running,
you must pay heed to the following warning instructions. ■Pay particular attention to moving engine parts (e.g. V-ribbed belt, alterna-
tor, radiator fan) and the high-voltage ignition unit - danger to life! ■ Never touch the electric wiring on the ignition system.
■ Avoid short circuits in the electrical system – particularly on the vehicle's
battery. ■ 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.■
The following warning instructions must be observed if work has to be car-
ried 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.
■
Read the information and warning instructions on the fluid containers.
■
Keep fluids in their original containers and keep out of reach of children!
■
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!
■
The bonnet must always be properly closed when driving. This is why after
closing the bonnet, the lock must always be checked to ensure it has engaged
properly.
■
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!
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.
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 Partner as part of the inspection service. 170General Maintenance
