If you do not want to confirm the command rSAP during each connection of the
telephone to the control unit, then you mu st carry out in the menu of the mobile
phone an authorization using the control unit.
The telephone deregisters from the GSM network and only the control unit ensures
the communication with the network. In the telephone only the interface for Blue-
tooth
® remains active. In this case, you can only select to separate from the device,
switch off the Bluetooth® connection or the number of the emergency call 112.
If the PIN was stored, an automatic selection and connection of the telephone take
place the next time the ignition is swit ched. Check on your mobile phone if the
automatic connection was established.
Connection terminated
The connection of the handsfree-system is terminated by means of Bluetooth
®:
•When removing the key from the ignition lock (during a telephone call, the
connection is disconnected).
•By switching off the Bluetooth® in the mobile phone.

Airbag system
Description of the airbag system
General information on the airbag system
The front airbag system is complementary to the three-point seat belts and offers
additional protection for the head and chest area of the driver and passenger in the
event of a frontal collision.
In the case of a violent side crash, the si de* and head* airbags reduce the risk of
injuries to the occupants on the part of the body facing the side of the accident
⇒ .
The airbag system is only functional after the ignition has been switched on.
The operational readiness of the airbag system is monitored electronically. The
airbag warning light comes on for a few seconds each time the ignition is switched
on.
The airbag system (according to vehicl e equipment) essentially consists of:
•an electronic control unit,
•front airbag for the driver and the front seat passenger*,
•Side airbags*,
•head airbags*,
•an airbag warning light in the instrument cluster,
•a front passenger airbag switch* ⇒page 182,
•an indicator light for a switched off fron t seat passenger airbag* in the middle
of the dash panel ⇒page 182.
A fault in the airbag system exists if:
•the airbag indicator light does not light up when the ignition is switched on,
•the warning light does not go out after about 4 seconds after the ignition is
switched on,
•the airbag indicator light goes out and comes on again after the ignition is
switched on,
•the airbag indicator light comes on or flickers when driving,
•an airbag indicator light showing a swit ched-off front passenger airbag* in the
middle of the dash panel flashes.
WARNING
•To enable the occupants of a car to be protected with the greatest
possible effect when the airbag is deployed, the front seats must be
⇒ page 164, “Correct seated position” co rrectly adjusted to match the body
size of the occupant.
•If you do not fasten the seat belts when driving, lean too far forward or
adopt an incorrect seated position, you are exposing yourself to increased
risk of injury in the event of an accident.
•Have the airbag system checked imme diately by a specialist garage if a
fault exists. Otherwise, there is a risk of the airbag not being activated in the
event of an accident.
•No modifications of any kind may be made to parts of the airbag system.
•It is prohibited to manipulate individual parts of the airbag system as this
might result in the airbag being deployed.
•The protective function of the airbag system is sufficient for only one
accident. The airbag system must then be replaced if the airbag has been
deployed.
•The airbag system needs no maintenance during its working life.
•If you sell your car, please hand over the complete vehicle documenta-
tion to the new owener. Please note that the documents relating to the
possibility of deactivating the front passenger airbag are also part of the
vehicle documents!
•If the vehicle or individual parts of the airbag system are scrapped, it is
essential to observe the relevant safety precautions. Škoda Service Partners
are familiar with these regulations.
•When disposing of vehicle or parts of the airbag system, it is important
to comply with the national legal requirements.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
When are the airbags deployed?
The airbag system is designed in such a way that the driver and front passenger
airbag are deployed in the event of a frontal collision of major severity.
In the case of a violent side crash , the side airbag* on the side of the car at which
the collision occurs, is deployed together with the head airbag*.
In certain accident situations, the front airbags as well as the side and head airbag
may be deployed together.
The airbags are not deployed in the case of minor frontal and side collisions, in the
case of rear-end collisi ons and vehicle rollover.
Deployment factors
It is not possible to state globally which deployment conditions apply to the airbag
system in every situation as the circumstances which exist in the case of accidents
vary greatly. An important role in this case , for example, is played by factors such as
the type of object (hard, soft) against whic h the vehicle impacts or the type of object
against which the vehicle impa cts, the angle of impact, the relative vehicle speed
during the accident etc.
A decisive factor for the deployment of the airbags is the deceleration which occurs
during a collision. The control unit analyses the nature of the collision and activates
the relevant restraint system. If the vehi cle deceleration which occurs and is meas-
ured during the collision remains below the prescribed reference values specified
in the control unit, the airbags are not deployed although the vehicle may well
suffer severe damage to the bodywork as a consequence of the accident.
The airbags are not deployed if:
•ignition off,
•a minor frontal collision,
•a minor side collision,
•a rear-end collision,
•rollover.
Note
•A grey white, non harmful gas is released when airbag is inflated. This is
perfectly normal and is not an indi cation of a fire in the vehicle.
•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.

Deactivation of airbags is envisaged only for particular instances, such as if:
•you must in exceptional cases use a child seat on the front passenger seat
where the child has its back to the directio n of travel of the vehicle (in some coun-
tries this must be in the direction of trav el due to other legal regulations applying)
⇒ page 184, “Important safety information regarding the use of child safety seats”
•you are not able to maintain the distance of at least 25 cm between middle of
steering wheel and chest, despite the driver seat being correctly adjusted,
•special attachments are required in the area of the steering wheel because of a
physical disability,
•you have installed other seats (e.g. orthopaedic seats without side airbags).
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 warning light for the airbag system lights up for 4 seconds after switching
on the ignition and then flashes for 12 seconds afterwards in 2 second intervals.
Front passenger airbags sw itched off using the switch for front passenger
airbags* in stowage compartmen t on the front passenger side:
•The airbag warning light comes on in the instrument cluster for about 4 seconds
each time the igniti on is switched on.
•Switching off airbags is indicated in the middle of the dash panel by the lighting
up of the indicator light   ⇒ fig. 186 .
Note
Your Škoda Service Partner will be able to advise you whether national legislation in
your country allows airbags in your vehicle to be deactivated, and which ones.
Switch for the front passenger airbag*
The front passenger airbag is deactivated with the switch.

Tyre inflation pressure-control system*
The tyre inflation pressure-control system compares with the aid of the ABS sensors
the speed and also the rolling circumference of the individual wheels. If the rolling
circumference of a wheel is changed, the warning light
 lights up in the instru-
ment cluster ⇒page 38 and an audible signal sound s. The rolling circumference of
the tyre can change if:
•the tyre inflation pressure is too low,
•the structure of the tyre is damaged,
•the vehicle is loaded on one side,
•the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill),
•snow chains are mounted,
•the temporary spare wheel is mounted,
•one wheel per axle was changed.
Basic setting of tyre inflation pressure-control system
After changing the tyre inflation pressures or after changing one or several wheels,
a basic setting of the system must be carried out as follows.
•Inflate all tyres to the specified inflation pressure ⇒page 237.
•Switch on the ignition.
•Press button ⇒fig. 199 for more than 2 seconds. While pressing the
button, the warning light  lights up. At the same time the memory of the system
is erased and the new calibration is star ted, which is confirmed with an audible
signal and then the warning light
 goes out.
•If the warning light  does not go out after the basic setting, there is a fault in
the system. Have the vehicle inspected by your nearest specialist garage.
Warning light
 lights up
If the tyre inflation pressure of at least on e wheel is insufficiently inflated in compar-
ison to the stored basic value, the warning light
 ⇒ lights up.
Warning light
 flashes
If the warning light flashes, there is a system fault. Have the vehicle inspected by
your nearest specialist garage.
WARNING
•When the warning light  lights up, immediately reduce the speed and
avoid sudden steering and brake mano euvres. Please stop the vehicle
without delay at the nearest possible stop and inspect the tyres and their
inflation pressures.
•The driver is responsible for the correct tyre inflation pressures. For this
reason, the tyre inflation pressures must be checked regularly.
•Under certain circumstances (e.g. sporty style of driving, wintry or
unpaved roads) the warning light  can be delayed or does not light up at
all.
•The tyre inflation pressure-control system does not take away the
responsability from the driver for the correct tyre inflation pressure.
Note
The tyre inflation pressure-control system:
•does not replace the regular tyre inflatio n pressure control, because the system
cannot detect an even pressure loss,

Driving and the Environment
202
Catalytic converter
Proper operation of the emission co ntrol system (catalytic converter)
is of major significance for drivin g your vehicle in an environmen-
tally conscious way.
Please refer to the following guidelines:
– For vehicles with petrol engine only refuel with unleaded petrol
⇒ page 219, “Grades of petrol”.
– Never run the fuel tank completely empty.
– Do not switch off the ignition while you are driving the vehicle.
– Do not pour too much oil into the engine ⇒page 228, “Replenishing
engine oil”.
– Do not tow-start the vehicle over a distance of more than 50 metres
⇒ page 253, “Tow-starting and towing vehicle”.
If you drive your vehi cle in a country in which unleade d petrol is not available, you
must have the catalytic converter replaced later when driving the vehicle into a
country in which use of a cata lytic converter is mandatory.
WARNING
•In view of the high temperatures which may be produced in the catalytic
converter, one should always park a vehicle in such a way that the catalytic
converter cannot come into contact with easily flammable materials below
the vehicle - a risk of fire!
•Never use additional underbody protection or corrosion-protection
agents for the exhaust pipes, catalyti c converters or heat shields. Such
substances might ignite when driving - risk of fire!
Caution
•Vehicles fitted with catalytic converter should neve r be allowed to let the fuel
tank to run completely empty. An irregular fuel supply can result in poor ignition or misfiring. Unburnt fuel may get into the exhaust system and damage the catalytic
converter.
•Filling the tank even only once with le
aded petrol will result in the catalytic
converter being destroyed.
•If you detect misfiring, a drop in perf ormance or irregular engine running when
driving, reduce your speed immediately and have the vehicle inspected by the
nearest specialist garage. The symptoms described may be caused by a fault in the
ignition system. Unburnt fuel may get in to the exhaust system and damage the
catalytic converter.
For the sake of the environment
Even if the exhaust system is operating properly, a sulphur-like exhaust odour may
be produced under certain operating condit ions of the engine. This depends on the
sulphur content of the fuel. It is often su fficient to refuel with unleaded premium-
grade petrol of a different brand or at a different filling station.
Driving in an economical and environmentally
conscious manner
General
Your personal style of driving is a major factor.
Your fuel consumption, any pollution of the environmental and the wear-and-tear
to the engine, brakes and tyres, depend essentially on three factors:
•your personal style of driving,
•the conditions under which your vehicle is operated,
•technical aspects.
You can easily improve your fuel economy by 10 - 15 percent by driving in an
economical way with foresight. This section is intended to provide you with a
number of tips on how to protect the en vironment and at the same time save
money.

Taking care of your vehicle and cleaning the vehicle
212
Automatic vehicle wash systems
The paintwork of the vehicle is sufficiently resistant that the vehicle can be washed
normally in automatic vehicle wash plants without any problem. The actual stress
to which the paintwork is subjected, however, depends greatly on the design of the
vehicle wash system, the filtering of the water and the type of washing and care
products used. If the paintwork of your vehicle appears mat after being washed or
even has scratches, point this out to the operator of the vehicle wash plant. Use a
different vehicle wash plant, if necessary.
There are no particular points to note be fore washing your vehicle in such a plant
other than the usual precautionary measur es (closing windows and sliding/tilting
roof, moving any factory-fitted aerials down flat against the bodywork, etc.).
If you have any particular atta ch e d p a r t s f i t te d t o y o u r c a r - s u ch a s s p o i l e r, ro o f ra ck
system, two-way radio aerial - it is best to first of all consult the operator of the car
wash plant.
It is important to degrease the lips of the windscreen wiper rubbers after passing
through the automatic vehicle wash system.
Caution
Do not screw the swivelling down roof aeri al tight before washing the vehicle in an
automatic vehicle wash sy stem - risk of damage!
Washing vehicle by hand
It is important to first soften the dirt with plenty of water and rinse it off as thor-
oughly as possible before wa shing your vehicle by hand.
One should then clean the vehicle using a soft washing sponge, washing glove or
a washing brush and only slight pressure. Work from the top to the bottom -
beginning with the roof. Only place slight pressure on the vehicle paintwork during
cleaning Only use a car shampoo for stubborn dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such areas. Rinse off the vehicle well after giving it a wash and dry it off using a chamois leather.
WARNING
•The ignition should always be switched off when you wash your vehicle -
risk of accident!
•Protect your hands and arms from sharp-edged metal parts when you
are cleaning the underfloor, the inside of the wheel housings or the wheel
trims - risk of cuts.
Caution
•Do not wash your vehicle in bright sunlight - risk of paint damage.
•Ensure that the jet of water is not aimed directly at the locks or at the door and
panel joints if you spray your vehicle in winter down with a hose - risk of freezing.
•Do not use any insect sponges, rough ki tchen sponges or similar cleaning prod-
ucts - risk of damage to the surface of paintwork.
For the sake of the environment
Only wash your vehicle at washing bays specifically reserved for this purpose. This
ensures that no water which may be cont aminated by oil flows into the sewage
system. It is not even permitted to wash your vehicle in certain areas except at such
specific washing bays.
Washing with a high-pressure cleaner
When you wash your vehicle with a high-pressure cleaner, it is essential to comply
with the instructions for use of the cleaning equipment. This applies in particular to
the pressure used and to the spraying distance . Maintain a sufficiently large
distance to soft materials such as rubber hoses or insulation material.
On no account use circular spray nozzles or so-called dirt cutters!

Taking care of your vehicle and cleaning the vehicle
216
Engine compartment
Good corrosion protection is very importan t, particularly in winter when one often
drives over its salt-strewn roads. One should therefore clean the whole engine
compartment before and after the salt spre ading period and treat with preservative
in order to prevent the salt from being destructive.
Škoda Service Partners have the cleaning agents and preservatives recommended
by the manufacturer and also the required equipment.
WARNING
•It is necessary to observe the guidelines given in the chapter before
working on the engine compartment ⇒page 225, “Working in the engine
compartment”.
•Let the engine cool down before cleaning the engine compartment.
Caution
•Engine cleaning may be only be und ertaken when the ignition is off.
•It is recommended to cover the generator before washing the engine compart-
ment.
For the sake of the environment
The dirty water produced by washing the engine has washed away petrol, and resi-
dues of grease and oil and should therefor e be cleaned by an oil separator. This is
why engine washing should only be undertake n in a specialist garage or at a fueling
station (when these are fitted with the required equipment).
Care of the interior of vehicle
Plastic parts, artificial leather and cloths
You can clean plastic parts and artificial le ather with a moist cloth. You should only
treat such parts with special solvent-free plastic cleaning and care products it
does prove to be adequate.
Upholstery cloth and cloth trim on the doors, luggage compartment cover, head-
liner etc. are best treated with special cleaning products, using if necessary a dry
foam and a soft sponge or brush.
We recommend using a cleaning product from Škoda genuine accessories offered
by your Škoda dealer.
Caution
Solvent-free cleaners attack the material and can damage it.
Fabric covers of electrically heated seats
Do not clean the seat covers moist as this may result in damage to the seat heating
system.
Clean such covers using special agents, for example dry foam.
Natural leather
Natural leather requires quite particular care and attention.
Leather should be treated from time to time according the following
guidelines depending on how much it is used.
Normal cleaning
– Clean soiled areas of the leather with slightly moistened cotton or
woollen cloth.

– Grip with the hand under the radiator grille and lift up the bonnet.
– Take the bonnet support out of its holder and set it in the opening designed for it ⇒page 224, fig. 210 .
Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the bonnet support into the hold er designed to hold it.
– Allow the bonnet to drop from a height of about 20 cm into the lock - bonnet do not press down on it !
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi ng! Wait long enough until the steam
or coolant has stopped escaping.
•For safety reasons, the bonnet must always be properly closed when
driving. One should therefore check that the lock has in fact engaged prop-
erly after closing the bonnet.
•Stop your vehicle immediately while driv ing if you notice that the lock is
not properly engaged and close the bonnet properly - risk of an accident!
Caution
Never open the bonnet using the hand le - danger of causing damage.
Working in the engine compartment
Particular care is required when carrying out any work in the engine
compartment!
There is a risk of injuries, scalding, accidents and fire when working in the
engine compartment, e.g. inspecting and replenishing oil and other fluids. For
this reason, it is essential to comply with the warning instructions stated below and with the general applicable
rules of safety. The engine compart-
ment of your car is a hazardous area ⇒ .
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi ng! Wait long enough until the steam
or coolant has stopped escaping.
•Switch off the engine and pull out the ignition key.
•Apply the handbrake firmly.
•If your vehicle is fitted with a ma nual gearbox, move the gearshift lever
into Neutral, or if it is fitted with automatic gearbox, move the selector lever
into position P.
•Allow the engine to cool down.
•Keep children clear of the engine compartment.
•Never spill oil and other fluids over the hot engine. Such fluids (e.g. the
antifreeze contained in the coolant) may ignite!
•Avoid short circuits in the electrical system - particularly on the battery.
•Never place your hand into the radiator fan as long as the engine is still
warm. The fan might suddenly start running!
•Never open the cap of the coolant expa nsion bottle as long as the engine
is still warm. The cooling system is pressurized!
•Cover over the cap of the coolant expansion reservoir with a large cloth
when opening it as protection for your face, hands and arms from hot steam
or hot coolant.
•Do not let objects, such as e.g cleaning cloth or tools lie in the engine
compartment.
•If you wish to work under the vehicle, you must secure the vehicle from
rolling away and support it with suitable supporting blocks: the car jack is
not sufficient for this - risk of injury!
•In cases where it be necessary to carry out inspection work when the
engine is running there is an additional risk from rotating parts (e.g. the V-
ribbed belt, alternator, radiator fan) and from the high-voltage ignition
system. Please observe in addition the following:
