Monitoring the airbag system
The functionality of the airbag system is also monitored electronically when one
airbag has been switched off.
If the airbag was switched off using diagnostic equipment:
› The airbag indicator light  illuminates for around 4
seconds after the ignition
is switched on and then flashes approximately another 12 seconds in 2 second
intervals.
The following applies if the airbag has been switched off using the key switch
in the storage compartment: › The airbag indicator light  comes on for around 4 seconds after the ignition is
switched on;
› Switched off airbags are indicated in the middle of the dash panel by the yellow
indicator light   in the display    coming on » Fig. 127 on
page 142. Note
■ The national regulations for switching off airbags must be observed.

Safety

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 168 , Unleaded petrol ;
› Do not pour too much oil into the engine
» page 172, 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. £
146 Driving Tips

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 stabilisation
The trailer stabilisation is an extension of the stabilisation control that works in
conjunction with the counter-steering assistance to reduce the amount the trail-
er "sways". After turning on the ignition, the ESC indicator light  in the instru-
ment cluster lights up for about 2 seconds longer than the ABS indicator light.
Prerequisites for stabilising the trailer.
› The towing device is factory-fitted or a compatible towing device has been ret-
rofitted.
› The ESC is active. The indicator light
 or  in the instrument cluster is not illu-
minated.
› The trailer is electrically connected to the towing vehicle by means of the trailer
socket.
› The speed is higher than approx. 60 km/h.
› Trailers must have a fixed drawbar.
› The ESC works for both braked and unbraked trailers.
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 31 , 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 indicator light
 in the instrument cluster starts to
flash. Wait a few minutes and check the level of coolant in the coolant expansion
bottle » page 174, Checking the coolant level .
The following guidelines must be observed » page 20, Coolant temperature/cool-
ant level  .
The coolant temperature can be reduced by switching on the heating. WARNING
■ The increased safety offered by the trailer stabilisation must not tempt you
to take greater risks than otherwise. ■ 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
■ The trailer stabilisation need not be able to correctly detect all of driving situa-
tions.
■ Trailers that sway slightly are not always detected by the trailer stabilisation
and thus are not stabilised accordingly.
■ Release the pressure on the accelerator pedal if the system is being regulated.
■ 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. £

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).
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.

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
170 General Maintenance

Radiator fan
First read and observe the introductory information and safety warn-
ings on page 169.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
After switching off the ignition, the radiator fan can intermittently continue to op-
erate for approx. 10 minutes.
ÐChecking the brake fluid
Fig. 144
Engine compartment: Brake fluid
reservoir
First read and observe the introductory information and safety warn-
ings on page 169.
The brake fluid reservoir is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 171.
› Check the level of brake fluid in the reservoir
» Fig. 144. The level must be be-
tween the “MIN” and “MAX” markings.
When driving, a slight drop in the fluid level is caused by the wear-and-tear and
automatic adjustment of the brake pads, and is therefore perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid lev-
el drops significantly within a short time or if it drops below the “MIN” marking. If
the brake fluid level is too low, this is indicated by the indicator light  lighting
up in the instrument cluster » page 19, Brake system .
ä
ä WARNING
If the fluid level has dropped below the MIN marking,  do not continue your
journey - risk of accident! Seek help from a
ŠKODA specialist garage.Ð Changing the brake fluid
First read and observe the introductory information and safety warn-
ings on page 169.
Brake fluid absorbs moisture. Over time it therefore absorbs moisture from the
environment. Excessive water in the brake fluid may be the cause of corrosion in
the brake system. The water content also lowers the boiling point of the brake
fluid.
The brake fluid must comply with the following standards or specifications:
› VW 50114;
› FMVSS 116 DOT4. WARNING
Using old brake fluid can result in severe stress on the brakes because of the
formation of vapour bubbles in the brake system. This greatly impairs the
braking efficiency and thus also the safety of your vehicle. CAUTION
Brake fluid damages the paintwork of the vehicle. Ð

Inspecting and replenishing

Improper handling of the vehicle battery can cause damage. We therefore recom-
mend that any work on the vehicle battery is carried out by a
ŠKODA Service Part-
ner.
There is a risk of injuries, scalding, accidents and burns when carrying out any
work on the battery and on the electrical system. For this reason, it is essential to
comply with the warning instructions stated below and with the general applica-
ble rules of safety. WARNING
■ The battery acid is strongly corrosive and must, therefore, be handled with
the greatest of care. Always wear protective gloves, eye and skin protection
when handling the vehicle battery. Corrosive fumes in the air irritate the air
passages and lead to conjunctivitis and inflammation of the air passages in
the lungs. They corrode tooth enamel. After contact with the skin, the acid
creates deep wounds which take a long time to heal. Repeated contact with
diluted acids causes skin diseases (inflammations, ulcers, slin cracks). Acids
coming into contact with water are diluted accompanied by significant devel-
opment of heat.
■ Do not tilt the battery otherwise battery electrolyte may flow out of the bat-
tery vent openings. Protect the eyes with safety glasses or a shield! There is
the danger of suffering blindness! If any battery electrolyte comes into con-
tact with your eyes, rinse the relevant eye immediately with clear water for
several minutes. Then consult a doctor immediately. ■ Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. If acid was
swallowed, seek immediate medical attention.
■ Keep children away from the vehicle battery.
■ When you charge a battery, hydrogen is released, and a highly explosive gas
mixture is also produced. An explosion can be caused through sparkling over
during unclamping or loosening of the cable plug while the ignition is on.
■ Bridging of the poles will create a short circuit (e.g. through metal objects,
cables). Possible consequences of a short circuit: Melting of lead struts, explo-
sion and burning of the battery, jets of acid spurting out.
■ It is prohibited to work with a naked flame and light, to smoke or to carry
out any activities which produce sparks. Avoid creating sparks when working
with cables and electrical devices. Strong sparking represents a risk of injury. WARNING (Continued)
■ Before carrying out any work on the electrical system, switch off the engine,
the ignition and all of the electrical components and disconnect the negative
terminal (-) on the battery. If you wish to replace a bulb it suffices to switch off
the relevant light.
■ Never charge a frozen or thawed vehicle battery - risk of explosion and
caustic burns! Replace a frozen vehicle battery.
■ Never jump-start vehicle batteries with an electrolyte level that is too low -
risk of explosion and caustic burns!
■ Never use a damaged vehicle battery - risk of explosion! Replace a damaged
vehicle battery immediately. CAUTION
■ The vehicle battery must only be disconnected if the ignition is switched off,
otherwise the vehicle's electrical system (electronic components) can be dam-
aged. When disconnecting the battery from the electrical system, first of all dis-
connect the negative terminal

(-) of the battery. Then disconnect the positive ter-
minal (+).
■ When connecting the battery to the electrical system, first connect the positive
terminal (+) of the battery. Then connect the negative terminal
(-). Under no cir-
cumstances must the battery cables be connected incorrectly - risk of a cable fire.
■ Ensure that battery acid does not come into contact with the bodywork - risk of
damage to the paintwork.
■ Do not place the battery in direct daylight in order to protect the vehicle battery
housing from the effects of ultra-violet light.
■ If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge. This is because certain electrical components consume electricity (e.
g.
control units) also in idle state. Prevent the battery from discharging by discon-
necting the battery's negative terminal or continuously charging the battery with
a very low charging current.
■ If the vehicle is frequently used for making short trips, the vehicle battery will
not have time to charge up sufficiently and may discharge. For the sake of the environment
A vehicle battery that has been removed is a special type of hazardous waste.
These must be disposed of in accordance with national legal regulations. Note
You should replace batteries older than 5 years. Ð

Inspecting and replenishing

Charging a vehicle battery
First read and observe the introductory information and safety warn-
ings on page 176.
A properly charged vehicle battery is essential for reliably starting the engine.
› Switch off the ignition and all of the electrical components.
› Only for “quick-charging”: Disconnect both battery cables (first of all “negative”,
then “positive”).
› Attach the terminal clamps of the charger to the battery terminals (red =
“posi-
tive
”, black = “negative”).
› Only now plug the mains cable of the charger into the power socket and switch
on the device.
› When charging is completed: Switch off the charger and remove the mains ca-
ble from the power socket.
› Only then disconnect the charger's terminal clamps.
› Reconnect the cables to the battery, if necessary (first of all
“positive”, then
“negative
”).
It is not normally necessary to disconnect the cables of the battery if you re-
charge the vehicle battery using low amperages (as for example from a mini-
charger). Refer to the instructions of the charger manufacturer.
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower)
must be used until full charging is achieved.
It is, however, necessary to disconnect both cables before charging the battery
with high amperages, so-called “ quick-charging”.
“Quick-charging” the vehicle battery is dangerous and requires a special charger
and specialist knowledge. We therefore recommend having the quick charging of
vehicle batteries undertaken by a ŠKODA specialist garage.
The vent plugs of the vehicle battery should not be opened for charging. CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 198, Jump-starting in vehicles with the

START-STOP
system . Ð
ä Disconnecting and reconnecting the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 176.
On disconnecting and reconnecting the vehicle battery the following functions
are initially deactivated or are no longer able to operate fault-free.

We recommend having the vehicle checked by a ŠKODA Service Partner to ensure
the full functionality of all electrical systems. Ð Replacing the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 176.
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable types of vehicle batteries can
be purchased from a

ŠKODA Service Partner.
We recommend that the battery is replaced by a ŠKODA Service Partner, where
the new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations. Ð

Inspecting and replenishing

Automatic load deactivation
First read and observe the introductory information and safety warn-
ings on page 176.
An intelligent vehicle power management system automatically takes various
measures at high loads on the vehicle battery to prevent discharging of the bat-
tery: This manifests itself by the following:
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where appropriate large consumers of power, e.g. seat heaters, rear window
heaters, voltage supply to the 12V power socket, have their power limited or in
case of emergency shut off completely. Note
Despite such intervention by the vehicle electric system management, the vehicle
battery may be drained. For example, when the ignition is switched on a long time
with the engine turned off or the side or parking lights are turned on during lon-
ger parking. Driving comfort is not put at risk by any shutting off of consumers.
Often the driver is not aware of it having taken place. Ðä
