Activating/deactivating the parking aid
The parking aid is activated automatically when
reverse gear is engaged and the
ignition is turned on. This is confirmed by a brief audible signal.
The parking aid is deactivated by removing the reverse gear. WARNING
■ The parking aid is not a substitute for the driver paying proper attention and
it is always the driver's responsibility to take care when reversing the vehicle
or carrying out similar manoeuvres. Pay particular attention to small children
and animals as they are not recognised by the parking aid sensors.
■ Before reversing or parking, check that there is no small obstacle, such as a
rock, thin post, trailer drawbar etc., in front of or behind the vehicle. Such ob-
stacles may not be recognised by the parking aid sensors.
■ Under certain circumstances, surfaces of certain objects and types of cloth-
ing cannot reflect the signals from the parking aid. Thus, these objects or peo-
ple who wear such clothing are not recognised by the parking aid sensors.
■ External sound sources can have a detrimental effect on the parking aid.
Under unfavourable conditions, objects or people may not be recognised. Note
■ If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. Have the fault
rectified by a ŠKODA specialist garage. ■ The sensors must be kept clean (free of ice, etc.) to enable the parking aid to
operate properly.
■ If the parking aid is activated and the selector lever of the automatic gearbox is
in the position P, the warning signal is interrupted (the vehicle cannot move). ÐCruise control system (CCS)
ä
Introduction
This chapter contains information on the following subjects:
Storing a speed 84
Changing a stored speed 84
Switching off the cruise control system temporarily 84
Switching off the cruise control system completely 84The cruise control system (CCS) maintains a constant speed, more than 30 km/h,
once it has been set, without you having to depress the accelerator pedal. This is
only possible within the range which is permitted by the power output and brak-
ing power of the engine.
The warning light
 illuminates in the instrument cluster when the cruise control
system is activated. WARNING
■ For safety reasons, the cruise control system must not be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads,
loose gravel) - risk of accident!
■ The saved speed may only be resumed if it is not too high for the current
traffic conditions.
■ Always switch off the cruise control system after use to prevent uninten-
tional use of the system. CAUTION
■ Always depress the clutch pedal if switching to the neutral position (vehicle
with a manual gearbox) when the cruise control system is switched on! Otherwise
the engine can rev up unintentionally.
■ The cruise control system is not able to maintain a constant speed when driving
in areas with steeper gradients. The weight of the vehicle increases the speed at
which it travels. Therefore, shift to a lower gear in good time or slow the vehicle
down by applying the foot brake. Note
It is not possible on vehicles fitted with an automatic gearbox to switch on the
cruise control system if the selector lever is in the position P, N or R. Ð

Starting-off and Driving

START/STOP
Fig. 85
Centre console: Button for the
START-STOP system
The START-STOP system helps you to save fuel while at the same time reducing
harmful exhaust emissions and CO 2 emissions.
The function is automatically activated each time the ignition is switched on.
In the start-stop mode, the engine automatically switches to the vehicle's idle
phase, e.g. when stopped at traffic lights.
Information regarding the current state of the
START-STOP system is indicated in
the display of the instrument cluster.
Automatic engine shut down (stop phase)
› Stop the vehicle (where necessary, apply the handbrake).
› Take the vehicle out of gear.
› Release the clutch pedal.
Automatic renewed engine restart (start phase).
› Depress the clutch pedal.
Switching the
START-STOP system on and off
The START/STOP system can be switched on/off by pressing the button  » Fig. 85.
When start-stop mode is deactivated, the warning light in the button lights up.
If the vehicle is in the stop phase when manually switching off the system, the
engine starts immediately.
The

START-STOP system is very complex. Some of the procedures are hard to
check without servicing. The general conditions for the proper functioning of the
START-STOP system are listed in the following overview. Conditions for the automatic engine shut down (stop phase)
› The gearshift lever is in Neutral.
› The clutch pedal is not depressed.
› The driver has fastened the seat belt.
› The driver's door is closed.
› The bonnet is closed.
› The vehicle is at a standstill.
› The factory-fitted towing device is not electrically connected to a trailer.
› The engine is at operating temperature.
› The charge state of the vehicle battery is sufficient.
› The stationary vehicle is not on a steep slope or a steep downhill section.
› The engine speed is less than 1

200 rpm.
› The temperature of the vehicle battery is not too low or too high.
› There is sufficient pressure in the braking system.
› The difference between the outdoor- and the set temperature in the interior is
not too great.
› The vehicle speed since the last time the engine was switched off was greater
than 3 km/h.
› No cleaning of the diesel particle filter takes place
» page 22.
› The front wheels are not turned excessively (the steering angle is less than 3/4
of a steering wheel revolution).
Conditions for an automatic restart (start phase)
› The clutch is depressed.
› The max./min. temperature is set.
› The defrost function for the windscreen is switched on.
› A high blower stage has been selected.
› The START STOP button is pressed.
Conditions for an automatic restart without driver intervention
› The vehicle moves at a speed of more than 3 km/h.
› The difference between the outdoor- and the set temperature in the interior is
too great.
› The charge state of the vehicle battery is not sufficient.
› There is insufficient pressure in the braking system.
If the driver's seat belt is removed for more than 30 seconds or the driver's door is
opened during stop mode, the engine must be started manually with the key. The
following messages in the instrument cluster display must be observed. £

Starting-off and Driving

Driving Tips
Driving and the Environment
The first 1 500 km
New engine
The engine has to be run in during the first 1 500 kilometres.
Up to 1 000 kilometres › Do not drive faster than 3/4 of the maximum speed of the gear in use, i.e. 3/4 of
the maximum permissible engine speed.
› No full throttle.
› Avoid high engine speeds.
› Do not tow a trailer.
From 1 000 up to 1
500 kilometres
› Gradually
increase the power output of the engine up to the full speed of the
gear engaged, i.e. up to the maximum permissible engine speed.
During the first operating hours the engine has higher internal friction than later
until all of the moving parts have harmonized. The driving style which you adopt
during the first approx.1

500 kilometres plays a decisive part in the success of
running in your car.
Never drive at unnecessarily high engine speeds even after the running-in period
is complete. The maximum permissible engine speed is marked by the start of the
red scale area of the revolutions counter. On vehicles fitted with a manual gear-
box, at the very latest shift up into the next gear when the red area is reached.
During acceleration (depressing the accelerator) exceptionally high engine
speeds are automatically reduced, yet the engine is not protected against too
high engine speeds which are caused by incorrectly shifting down the gears re-
sulting in a sudden increase of the engine speeds above the permitted maximum
revolutions which can lead to engine damage.
For a vehicle fitted with a manual gearbox the converse situation also applies: Do
not drive at an engine speed that is too low. Shift down a gear when the engine
is no longer running smoothly. Observe the recommended gear » page 11, Recom-
mended gear . CAUTION
All the speed and engine revolution figures apply only when the engine is at its
normal operating temperature. Never rev up a cold engine when the vehicle is
stationary or when driving in individual gears. For the sake of the environment
Not driving at unnecessarily high engine revolutions and shifting to a higher gear
as early as possible are ways to minimise fuel consumption and operating noise
levels and protects the environment. Ð New tyres
New tyres have to be “
run in” since they do not offer optimal grip at first. Drive
especially carefully for the first 500 km or so. Ð New brake pads
New brake pads initially do not provide full braking efficiency. The brake pads
must initially be “run in

”. Drive especially carefully for the first 200 km or so. Ð Catalytic converter
Proper operation of the emission control system (catalytic converter) is of major
significance for driving your vehicle in an environmentally conscious way.
The following guidelines must be observed: › Vehicles fitted with a petrol engine must always be refueled with unleaded pet-
rol » page 135, Unleaded petrol ;
› Do not pour too much oil into the engine
» page 139, Checking the engine oil
level;
› Do not switch off the ignition while driving.
If you drive your vehicle in a country in which unleaded petrol is not available, you
must have the catalytic converter replaced later when driving the vehicle into a
country in which use of a catalytic converter is mandatory. £

Driving and the Environment

Note
Observe the recommended gear » page 11, Recommended gear .ÐAvoiding full throttle
Fig. 109
Principle sketch: Fuel consump-
tion in litres/100 km. and speed
in km/h.
Driving more slowly means saving fuel.
Sensitive use of the accelerator will not only significantly reduce fuel consump-
tion but also positively influence environmental pollution and wear of your vehi-
cle.
The maximum speed of your vehicle should, as far possible, never be used. Fuel
consumption, pollutant emissions and vehicle noises increase disproportionally at
high speeds.
The » Fig. 109 shows the ratio of fuel consumption to the speed of your vehicle.
Fuel consumption will be halved if only three-quarters of the possible top speed
of your vehicle is used. ÐReducing idling
Idling also costs fuel.
In vehicles not equipped with the
START-STOP system, turn off the engine when
in a traffic jam, at a level crossing or traffic lights with longer wait times. Even af-
ter just 30 - 40 seconds you will have saved more fuel than that is needed when
you start the engine up again. If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant emissions, though, are particularly
high in the warming-up phase. Therefore, start driving as soon as the engine has
started, whereby high engine speeds should be avoided. Ð Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
By having your vehicle regularly maintained by a ŠKODA

specialist garage, you
create the conditions needed for driving economically. The maintenance state of
your vehicle has a positive effect on traffic safety and value retention
A poorly tuned engine can result in a fuel consumption which is 10 % higher than
normal.
Also check the oil level when refuelling. Oil consumption is dependent to a con-
siderable extent on the load and speed of the engine. Oil consumption could be
as high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine has a higher oil consumption at first, and rea-
ches its lowest level only after a certain running in time. The oil consumption of a
new vehicle can therefore only be correctly assessed after driving about
5 000 km. For the sake of the environment
■ Additional improvements to the fuel economy can be made by using synthetic
high-lubricity oils.
■ Regularly check the ground under the vehicle. Have your vehicle inspected by a
ŠKODA specialist garage if you find any stains caused by oil or other fluids on the
floor. Note
We recommend that your vehicle is serviced on a regular basis by a ŠKODA Serv-
ice Partner. Ð
121
Driving and the Environment

Avoid short distances
Fig. 110
Principle sketch: Fuel consump-
tion in l/100 km at different tem-
peratures
Short distances result in an above-average high fuel consumption. We therefore
recommend avoiding distances of less than 4 km if the engine is cold.
A cold engine consumes the most fuel immediately after the start. Fuel consump-
tion drops to 10 litres/100 km after just 1 kilometre. The consumption stabilises
once the engine and catalytic converter have reached their operating tempera-
ture.
An important factor in this connection is also the ambient temperature. The im-
age » Fig. 110 shows the different levels of fuel consumption after driving a cer-
tain distance at a temperature of +20 °C and a temperature of -10 °C. Your vehicle
has a higher fuel consumption in the winter than in the summer. ÐChecking tyre inflation pressures
Tyres which are correctly inflated save fuel.
Always ensure the tyre inflation pressure is correct. The rolling resistance will be
increased if the tyre filling pressure is too low. This will not only increase fuel con-
sumption but also tyre wear and the driving behaviour will worsen.
Always check the tyre inflation pressure when the tyres are cold. ÐAvoid unnecessary ballast
Transporting ballast costs fuel.
Each kilogramme of weight increases the fuel consumption. It is worth checking
the boot to avoid transporting any unnecessary ballast. It is particularly in town traffic, when one is accelerating quite often, that the ve-
hicle weight will have a significant effect upon the fuel consumption. A rule of
thumb here is that an increase in weight of 100 kilograms will cause an increase
in fuel consumption of about 1 litre/100 kilometres.
At a speed of 100 - 120 km/h, a vehicle fitted with a roof rack cross member with-
out a load will use about 10

% more fuel than normal due to the increased aero-
dynamic drag. Ð Saving electricity
When the engine is running, the alternator generates and supplies electrical pow-
er. If more electrical components of the electrical system are switched on, more
fuel is needed to operate the alternator. We therefore recommend switching off
electrical components if these are no longer required. Ð Environmental compatibility
Environmental protection has played a major role in the design, selection of mate-
rials and manufacture of your new

ŠKODA. Particular emphasis has been placed
on the following points:
Design measures
› Joints designed to be easily detached.
› Simplified disassembly due to the modular structure system.
› Improved purity of different classes of materials.
› Identification of all plastic parts in accordance with VDA Recommendation 260.
› Reduced fuel consumption and exhaust emission CO
2.
› Minimum fuel leakage during accidents.
› Reduced noise.
Choice of materials › Extensive use of recyclable material.
› Air conditioning filled with CFC-free refrigerant.
› No cadmium.
› No asbestos.
› Reduction in the “vaporisation” of plastics.
Manufacture › Solvent-free cavity protection.
› Solvent-free protection of the vehicle for transportation from the production
plant to the customer. £
122 Driving Tips

Driving through water on the street
Fig. 111
Driving through water
The following must be observed to avoid damage to the vehicle when driving
through bodies of water (e.g. flooded roads):
› Therefore determine the depth of the water before driving through bodies of
water. The water level must fit around the strut on the side member as a maxi-
mum » Fig. 111;
› Do not drive any faster than at a walking speed. At a higher speed, a water
wave can form in front of the vehicle which can cause water to penetrate into
the air induction system of the engine or into other parts of the vehicle;
› Never stop in the water, do not reverse and do not switch the engine off;
› Deactivate the
START-STOP system before driving through water » page 85,
START/STOP. WARNING
■ Driving through water, mud, sludge etc. can reduce the braking power and
extend the braking distance - risk of accident!
■ Avoid abrupt and sudden braking immediately after water crossings.
■ After driving through bodies of water, the brakes must be cleaned and dried
as soon as possible by intermittent braking. Only apply the brakes for the pur-
pose of drying and cleaning the brake discs if the traffic conditions permit this.
Do not place any other road users in jeopardy. CAUTION
■ When driving through bodies of water, parts of the vehicle such as the engine,
gearbox, chassis or electrics can be severely damaged.
■ Oncoming vehicles can generate water waves which can exceed the permissible
water level for your vehicle. ■
Potholes, mud or rocks can be hidden under the water making it difficult or im-
possible to drive through the body of water. ■ Do not drive through salt water. The salt can lead to corrosion. Any vehicle parts
that have come into contact with salt water must be rinsed immediately with
fresh water. Note
After driving through a body of water, we recommend that the vehicle is checked
by a
ŠKODA specialist garage. Ð124
Driving Tips

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 156, 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 149 ,
Service life of tyres.
Trailer load
The permissible trailer load must not be exceeded under any circumstan-
ces » page 176, 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 39 , Headlight beam adjustment .
Driving speed
For safety reasons, do not drive faster than the maximum permissible speed indi-
cated on the trailer. £
125
Towing a trailer

Immediately reduce your speed as soon as even the slightest swaying of the trail-
er is detected. Never attempt to stop the trailer from “swaying” by accelerating.
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.
Trailer is connected to the anti-theft alarm system.
› If the vehicle is factory-fitted with an anti-theft alarm system and a towing de-
vice.
› If the trailer is electrically connected to the towing vehicle by means of the trail-
er socket.
› If the electrical system of the vehicle and trailer is fully functional.
› If the vehicle is locked with the car key and the anti-theft alarm system is acti-
vated.
When the vehicle is locked, the alarm is activated as soon as the electrical con-
nection to the trailer is interrupted.
Always deactivate the anti-theft alarm system before a trailer is connected/dis-
connected. Otherwise, the anti-theft alarm system could accidentally be trig-
gered » page 30, Anti-theft alarm system .
Engine overheating
If the needle for the coolant temperature gauge moves into the right-hand area
or the red area of the scale, the speed must be reduced immediately. Stop and
switch off the engine if the warning light  in the instrument cluster starts to
flash. Wait a few minutes and check the level of coolant in the coolant expansion
bottle » page 141, Checking the coolant level .
The following guidelines must be observed » page 19, Coolant temperature/cool-
ant level   .
The coolant temperature can be reduced by switching on the heating. WARNING
■ Adapt your speed to the conditions of the road surface and to the traffic sit-
uation.
■ Improper or incorrectly connected electric cables can energise the trailer and
cause functional faults to the vehicle's entire electrical system as well as acci-
dents and severe injuries.
■ Any work on the electrical system must be carried out only by ŠKODA spe-
cialist garages.
■ Never directly connect the trailer's electrical system with the electrical con-
nections for the tail lights or other current sources. CAUTION
■ Avoid abrupt and sudden driving/braking manoeuvres.
■ When the ball rod is removed, the mounting shaft must be sealed with an ap-
propriate cover. This prevents foreign matter from penetrating into the mounting
shaft. See the fitting instructions for the towing device. Note
■ We recommend that you also have your vehicle inspected between service in-
tervals if you tow a trailer frequently. ■ The handbrake on the towing vehicle must be put on when coupling and decou-
pling the trailer.
■ For technical reasons, trailers with rear LED lights cannot be connected to the
anti-theft alarm system. Ð
126 Driving Tips

Diesel fuel
First read and observe the introductory information and safety warn-
ings on page 134.
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
