Front airbags
Description of the front airbags
The airbag system is not a su bstitute for the seat belt!
The front airbag for the driver is housed in the steering wheel ⇒fig. 125. The front airbag for the front passenger* is housed in the dash panel above the storage compartment ⇒fig. 126. The installation positions are each marked with the “AIRBAG” logo.
The front airbag system is complementary to the three-point seat belts and offers additional protection in the head and chest area of the driver and passenger in the
event of a frontal collision ⇒ in “Important safety information regarding the front airbag system” on page 131.
The airbag is not a substitute for the seat belt, but is part of the complete passive vehicle safety concept. Please note that an airbag can only offer you optimal protection in combination with a seat belt which is fastened .
Apart from their normal protective function, a further task of the seat belts is to also hold the driver and front passenger in a correct seated position in the event of a frontal collision so as to enable the fr ont airbags to offer the maximum protection.
You should therefore always fasten the seat belts, not only because this is required by law, but also for safety reasons and for your own protection ⇒page 122, “Why seat belts?”.
Caution
The dash panel must be replaced afte r the front passenger airbag has been deployed.
Function of the front airbags
Risk of injury to the head and chest area is reduced by fully inflated
airbags.
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 certain accident situations both the front airbags as well as the head and side airbags may be deployed together.
If the airbags are deployed, the airbags are filled with a propellant gas and inflated in front of the driver and front passenger ⇒page 130, fig. 127. The airbags inflate in fractions of a second and at a high speed in order to be able to offer that addi- tional protection in the event of an acci dent. The forward movement of the driver and of the front passenger is cushioned when they make contact with the fully inflated airbag and the risk of injury to head and chest is thus reduced.
The specially developed 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.
A grey white, non harmful gas is released when airbag is inflated. This is perfectly normal and is not an indication of a fire in the vehicle.
The airbag develops enormous forces when triggered, which can lead to injuries if the sitting position or seated position is not correct ⇒ in “Important safety information regarding the front airbag system” on page 131.
Important safety information regarding the front airbag system
Correct use of the airbag system considerably reduces the risk of
injury!
WARNING
•Never transport children on the front seat of a vehicle without using a proper restraint system. If airbags are deployed in the event of an accident, the child might suffer severe or even fatal injuries!
•For the driver and front passenger it is important to maintain a distance of at least 25 cm from the steering wheel or dash panel ⇒fig. 128. Not main- taining 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 occu- pant.
•It is essential to always switch off ⇒page 135, “Deactivating an airbag” the front passenger airbag when attaching a child safety seat on the front passenger seat where the child is seated with its back facing in direction of travel (in some countries al so when the child is facing the direction of travel). If this is not done, there is a risk of the child suffering severe or even fatal injuries if the front passenger airbag is deployed. In certain countries national legal provisions also requir e that the side or head passenger airbags be deactivated. When transpor ting a child on the front passenger seat, please comply with the appropriate national regulations regarding the use of child safety seats.
•There must not by any further persons, animals or objects positioned between the front seated occupants and the deployment area of the airbag.
•The steering wheel and the surface of the airbag module in the dash panel on the passenger side must not be stuck onto, covered or modified in any other way. These parts should only be cleaned with a dry cloth or a cloth moistened with water. No objects such as cup holders, mobile phone mounts, etc. may be attached to the covers of the airbag modules or be located within the immediate area.
•No modifications of any kind may be made to parts of the airbag system. Any work on the airbag system includ ing installing and removing system components because of other repair work (e.g. removing the steering wheel) must only be carried out by a specialist garage.
•Never carry out changes on the front bumper or on the body.
•Never place any objects on the dash panel on the front passenger side.

clothing. In addition, it is not permitted to use clothes hangers for hanging up items of clothing.
•There must not be any other persons (e.g. children) or animals between the car occupant and the deployment ar ea of the head airbag. In addition, none of the occupants should lean their head out of the window when driving, or extend their arms and hands out of the window.
•The sun visors must not be swivelled to the side windows into the deployment area of the head airbags if any objects, such as ball-point pens etc. are attached to them. This might result in injuries to the occupants if the head airbag is deployed.
•Installing impermissible accessories in the area of the head airbags may considerably impair the protection offered by the head airbag in the event of it being deployed. When the deployed head airbag is inflated, parts of the accessories fitted may in certain circumstances be thrown into the interior of the car and cause injuries to the occupants ⇒page 193.
•Any work on the head airbag system including installing and removing system components because of other re pair work (e.g. removing headliner) must only be carried ou t by a specialist garage.
Deactivating an airbag
Deactivating airbags
If any airbags have been deactivated, switch them on again as soon
as possible so that they are able to again provide their proper protec-
tion.
There is the technical means installed within your vehicle to switch off the front, side* or head airbag* (take out of commission).
This is why you should have the deactiva tion of the airbags carried out by a specialist garage.
On vehicles equipped with the switch for de activation of the airbags, you can deac- tivate the front passenger airbag or passen ger side airbag by means of this switch ⇒ page 136.
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 travel due to other legal regulations applying) ⇒ page 137, “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 of f using diagnostic equipment:
•The airbag indicator light in the instrument cluster lights up for about 3 seconds after switching on the ignition and then flashes after that for about 12 seconds.
If the airbag was switched off using the airbag switch* on the side of the dash panel:
•The airbag warning light comes on in the instrument cluster for about 3 seconds each time the ignition is switched on.
•Switching off airbags is indicated in the middle of the dash panel by the lighting up of the indicator light   ⇒page 136, fig. 134.
Note
Your Škoda Service Partner will be able to advise you whether national legislation in your country allows airbags in your vehi cle to be deactivated, and which ones.

Driving Tips
Intelligent Technology
Electronic stability programme (ESP)*
General
General
The ESP aids you maintain control of your vehicle in situations in borderline driving situations such as when negotiating a curve too fast. The risk of skidding is reduced and your car thus offers greater driving stability depending on the conditions of the road surface. This occurs at all speeds.
The following systems are integrated into the electronic stability programme:
•Electronic Differential Lock (EDL),
•Traction control system (TCS),
•Antilock brake system (ABS),
•Brake Assist.
Operating principle
The ESP switches on automatically when the engine is started and then conducts a self-test. The ESP control unit processes data from the individual systems. It also processes additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehi cle about its vertical axis, the lateral accel- eration of the vehicle, the brakin g pressure and the steering angle.
The direction which the driver wishes to ta ke is determined based on the steering angle and the speed of the vehicle and is constantly compared with the actual behaviour of the vehicle. If differences exis t, such as the car beginning to skid, the ESP will automatically brake the appropriate wheel.
The car is stabilised again by the forces which take effect when the wheel is braked. Intervention into the brake system takes place primarily on the outer front wheel of a vehicle which tends to oversteer (tendency for the rear of the vehicle to break away) while occurs this is on the inner re ar wheel of a vehicle which tends to under- steer (tendency to shift out of the curve). This braking control cycle is accompanied by noises.
The ESP operates in combination with the ABS ⇒page 149, “Antilock brake system (ABS)*”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light ⇒page 27 lights up in the instrument cluster when there is a fault on the ESP.
Switching off
You can switch the ESP off and on again as you wish, by pressing the button ⇒ fig. 145. The ESP warning light ⇒page 27 lights up in the instrument cluster when the ESP is switched off.
The ESP should normally always be switched on. It may be good practice in certain exceptional cases, such as when you wish to have wheel slip, to switch off the system.

WARNING
•Never switch off the engine before the vehicle is stationary.
•The brake booster only operates when the engine is running. Greater physical effort for braking is required when engine is switched off. Because if you do not stop as normal, this can cause an accident and severe injuries.
Antilock brake system (ABS)*
ABS prevents the wheels locking when braking.
General
The ABS contributes significan tly to enhancing the active safety of your vehicle. Compared to a car not fitted with the ABS brake system, you are able to retain optimal steering ability even during a fu ll brake application on a slippery road surface because the wheels do not lock up.
You must not expect, however, that the br aking distance will be shorter under all circumstances as a result of the ABS. Th e braking distance for example on gravel and fresh snow, when you should anyway be driving slowly and cautiously, will be longer.
Operating principle
As soon as the vehicle speed has increase d to about 20 km/hour an automatic test procedure is conducted during which you wi ll be able to hear a pumping noise for about 1 second.
The brake pressure will be reduced on a wheel which is rotating at a speed which is too low for the speed of the vehicle and tend ing to lock. This control cycle is notice- able from a pulsating movement of the brake pedal which is accompanied by noises. This is consciously intended to pr ovide the driver with the information that the wheels are tending to lock (ABS control range). You must always keep the brake pedal depressed to enable the ABS to optima lly control the brake application in this braking range. Never interrupt the application of the brakes!
WARNING
•The ABS can also not overcome the physic al limits of your vehicle. Please do not forget this, particularly when driv ing on icy or wet road surfaces. If the ABS is operating within the control ra nge, adapt your speed immediately to the conditions of the road surface and the traffic situation. The increased safety offered by the ABS must not tempt you to take greater risks than otherwise - risk of an accident!
•The normal braking system is still fully functional if there is an ABS fault. Visit a specialist garage as quickly as po ssible and adjust your style of driving to take account of the ABS fault in the meantime since you will not know how great the damage is.
Note
•A warning light comes on if a fault occurs in the ABS system ⇒page 27.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign- ment of tyres and wheels) can in fluence the function of the ABS ⇒page 193, “Accessories, changes and replacement of parts”.
Brake Assist*
During a severe brake application (e.g. if a hazard exists), the Brake Assist increases the braking force and thus makes it possible to rapidly produce the pressure required in the brake system.
The majority of drivers do apply the brakes in good time in dangerous situations, but do not depress the brake pedal with suff icient pressure. Consequently, it is not possible for the car to achieve its maxi mum deceleration and the car covers a greater distance than necessary.
The Brake Assist is activated by the very quick operation of the brake pedal. In such cases, a much greater braking pressure ex ists than during a normal brake applica- tion. This makes it possible, even with a relatively low resistance of the brake pedal, to produce an adequate pressure in the brake system in the shortest possible time, which is required for maximum deceleration of the car. You must apply the brake

Intelligent Technology150
pedal firmly and hold it in this position in order to achieve the shortest possible braking distance.
The Brake Assist is able to help you achieve a shorter braking distance in emergency situations by rapidly producing the pressure required in the brake system. It fully exploits the attributes of the ABS. After you release the brake pedal, the function of the Brake Assist is automatically switched off and the brakes operate in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist function is also not available. Further information on the ESP ⇒page 145.
WARNING
•The Brake Assist is also not able to overcome the physical limits of your car in terms of the braking distance required.
•Adapt your speed to the conditions of the road surface and to the traffic situation.
•The increased safety offered by the Brake Assist must not tempt you to take a greater safety risk than otherwise.
Electrohydraulic power steering
The power steering enables you to steer the vehicle with less physical force.
The steering characteristics can be changed by a specialist garage.
You will place great stresses on the power st eering system if the steering is turned to full lock when the vehicle is stationary. Turning the steering to full lock in such a situation will be acco mpanied by noises.
It is still possible to fully steer the vehicle if the power steering fails or if the engine is not running (vehicle being towed in). The only difference is that greater physical effort is required.
It is possible that the hydraulic pump of the power steering will not run due to the low vehicle network voltage if the battery has gone flat and the engine must started with the help off jump leads. This conditio n will be indicated by lighting up of the warning light.
The power steering operates again if the battery is charged to a specific range when engine is running. It also operates again, if the engine can be started with its own battery.
Caution
Do not leave the steering at full lock fo r more than 15 seconds when the engine is running - risk of damagi ng the power steering!
Note
Have the steering inspected as soon as possible by a specialist garage if there is a leak or fault in the system.
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 infla- tion pressure and therefore the rolling circumference of a wheel has changed signif- icantly, the warning light  lights up in the dash panel ⇒page 26. The tyre inflation pressure-control system function s late or too sensitively if:
•the structure of the tyre is damaged,
•the vehicle is loaded to one side or with a load on the roof,

Intelligent Technology151
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistancePraktikTechnical Data
•the wheels of an axle are loaded heavily (e.g. when towing a trailer or when driving uphill or downhill),
•the vehicle is operated in unfavourable winter conditions or on an unfirm ground,
•snow chains or emergency wheel are mounted,
•the driver has a sporty style of driving (with sharp acceleration and high speed when cornering).
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 187.
•Switch on the ignition.
•Press button   ⇒page 150, fig. 147 for more than 2 seconds. While pressing the button, the warning light  lights up. At the same time the basic values are stored, which is confirmed with an acoustic sound 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.
Function description
After the basic setting of the system the “a daptation” of the tyre inflation pressures and then the tyre pressure control in the individual tyres are performed.
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. Inflate all tyres to the specified inflation pressure ⇒page 187, “Tyre life” and then perform a basic setting of the system.
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 correc t 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,
•cannot warn in case of very rapid tyre inflation pressure loss, e.g. in case of sudden tyre damage. In this case carefully bring the vehicle to a standstill without sudden steering movements and without sharp braking.

Taking care of your vehicle and cleaning the vehicle167
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistancePraktikTechnical Data
Wheels
Steel wheels
You should also thoroughly wash the wheels and wheel trims when giving your vehicle its regular wash. This prevents an y brake dust, dirt and road salt from sticking to the wheel hubs. You can remove stubborn brake abrasion adhering to t h e w h e e l s w i t h a n i n d u s tr i a l c l e a n e r. To u c h u p a n y d a m a g e to t h e p a i n tw o r k o n th e wheels before rust is able to form.
Light alloy wheels
Regular care of light alloy wheels is necessary in order to retain their decorative appearance over long periods. It is partic ularly important to remove any road salt and brake abrasion from light alloy wheels every two weeks, otherwise the surface will suffer. Wash thoroughly and then treat the wheels with a protective product for light alloy wheels which does not contain any acidic components. You should provide the wheel hubs with a hard wax la yer every three months. You must not use any products which cause abrasion when treating the wheel hubs. Any damage to the paint layer on the wheel hubs must be touched up immediately.
We recommend using a preservative from Škoda genuine accessories offered by your Škoda dealer.
WARNING
One should remember when cleaning th e wheels that moisture, ice and road salt may adversely affect braking ef ficiency - risk of an accident!
Note
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, ca n cause premature wear of the steering. This means it is necessary to remove the dirt.
Underbody protection
The underside of your vehicl e is protected for life against chemical and mechanical influences.
One cannot, however, completely rule out damage to the protective layer when driving so we recommend that you inspect the protective layer on the underside of your vehicle and on the chassis at certain in tervals - this is best done at the begin- ning and end of the winter - and to touch up any damaged areas.
Škoda Service Partners have suitable spray products available as well as the neces- sary equipment and are familiar with the instructions for use. We therefore recom- mend to have repairs and additional co rrosion protection measures preferably carried out by a Škoda Service Partner.
WARNING
Never use additional underbody protection or corrosion-protection agents for the exhaust pipes, catalytic converte rs, heat shields or diesel particle filter*. When the engine reaches its operating temperature, these substances might ignite - risk of fire!
Protection of hollow spaces
All the cavities of your vehicle which are at risk from corrosion are protected for life by a layer of protective wax applied in the factory.
This wax protection does not require to be inspected or re-treated. Please remove any small amount of wax which flows out of the cavities at high temperatures with a plastic scraper and clean the spot using petroleum cleaner.
WARNING
Safety and environmental protection regulations should observed when using petroleum cleaner to re move wax - a risk of fire!
