Seat belts
Why seat belts?
It is a proven fact that seat belts offer good protection in accidents ⇒fig. 118. Thus wearing a seat belt is a legal requirement in most countries.
Seat belts which have been correctly fastened and adjusted hold the occupants of the car in the correc t seated position ⇒fig. 118. The belts reduce the kinetic energy (energy of motion) to a considerable extent. They also prevent uncontrolled move- ments which, in turn, may well result in severe injuries.
The occupants of a vehicle who have fastened and correctly adjusted their seat belt, profit to a major extent from the fact that the kinetic energy is optimally absorbed by the belts. The structure of the front end of the vehicle and other passive safety measures, such as the airbag system, also contribute to reducing the kinetic energy. The energy produced is thus absorbed and there is less risk of injury.
Accident statistics prove that seat belts which are fastened and properly adjusted reduce the risk of an injury and enhance the chance of survival in a major accident ⇒ page 123.
It is important that you pay attention to safety measures, particularly when trans- porting children in the vehicle ⇒page 137, “Transporting children safely”.
WARNING
•Fasten your seat belt each time before setting off, also when driving in town! This also applies to the people seated at the rear - risk of injury!
•Expectant women must also always wear a seat belt. This is the only way of ensuring optimal protection for the unborn child ⇒page 124, “Fastening three-point seat belts”.
•It is important for the belt webbing to be properly routed if the seat belts are to offer the maximum protection. You can see a description of how safety belts should be fitted pr operly on the next pages.
Note
Please comply with any differing legal requirements when using the seat belts.

The physical principle of a frontal collision
The physical principle of a frontal accident can be explained quite simply:
Motion energy, so-called kinetic energy, is produced as soon as the vehicle is moving, both for the vehicle and its occupants. The magnitude of this kinetic energy depends essentially on the speed at which the vehicle is travelling and on the weight of the vehicle and the occupants. The greater the speed and weight increase,
the greater the amount of energy which has to be absorbed in the event of an acci- dent.
The speed of the vehicle is, nevertheless, the most important factor. Doubling the speed of the vehicle from 25 km/h up to 50 km/hour increases the kinetic energy four times.
The common opinion that it is possible to support your body in a minor accident with your hands, is incorrect. Even in a collision at only a low speed, the forces acting on the body are such that it is no longer possible to support your body.
Even if you only drive at a speed within the range from 30 km/hour to 50 km/hour, the forces which are produced on your body in the event of an accident can easily exceed 10.000 N (Newton). This equals a weight of one tonne (1 000 kg).
In the event of a frontal collision, occupants of the car not wearing a seat belt, are thrown forward and strike in an uncontrolle d way parts of the interior of the car, such as steering wheel, dash panel, windscreen, ⇒fig. 119. The occupants of a vehicle who have not fastened their seat belts may even be thrown out of the vehicle. This can resu lt in fatal injuries.
It is also important that rear seat occupants fasten their seat belts as they will other- wise be thrown through the vehicle in an uncontrolled manner in the event of an accident A rear seat passenger who has not fastened the seat belt is a danger not only to himself but also fo r those seated at the front ⇒fig. 120.
Important safety information regarding the use of
seat belts
The correct use of the seat belts considerably reduces the risk of
injury!
WARNING
•The belt webbing must not be jammed in-between at any point or twisted, or chafe against any sharp edges.
•It is important that the belt webbing is properly routed if the seat belts are to offer their maximum protection ⇒page 124, “How are seat belts correctly fa stened?”.

Airbag system128
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 in the head and chest area of the driver and passenger in the event of a frontal collision.
In the event of a side collision, the side airbags reduce the risk of injury to the occu- pants to the part of their 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,
•the front airbags for the driver and front passenger ⇒page 130,
•the side airbags ⇒page 132,
•Head airbags ⇒page 133,
•an airbag warning light in the instrument cluster ⇒page 28,
•a front passenger airbag switch* ⇒page 136,
•an indicator light for a switched off front seat passenger airbag* in the middle of the dash panel ⇒page 136.
A fault in the airbag system exists if:
•the airbag indicator light does not light up when the ignition is switched on,
•the airbag indicator light does not go out after about 3 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 119, “Correct seated position” correctly 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.

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.

•when driving with snow chains,
•when driving in deep snow or on a loose surface,
•when it is necessary to rock a car free when it has become stuck.
then you should switch on the ESP again.
WARNING
It is also not possible for the ESP to overcome the physical limits of the vehicle. Even if a vehicle fitted with ESP you should still always adapt your style of driving to the condition of the road surface and the traffic situation. This particularly applies when driving on slippery and wet roads. The increased safety offered must not tempt you to take greater risks than other- wise - risk of an accident!
Note
•All four wheels must be fitted with the same tyres in order to achieve problem-free operation of the ESP. Differing rolling circumferences of the tyres can lead to an undesirable reduction in the engine output.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other assign- ment of tyres and wheels) can influence the function of the ESP ⇒page 193, “Accessories, changes and replacement of parts”.
Traction control system (TCS)*
The traction control system prevents the driven wheels from spinning
when accelerating.
General
The TCS makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditions of the road surface are unfavourable.
Operating principle
The TCS switches on automatically when th e engine is started and then conducts a self-test. The system monitors the speeds of the driven wheels with the aid of the ABS sensors. If the wheels ar e spinning, the force transmitted to the road surface is automatically adapted by reducing the engi ne speed. This occurs at all speeds.
The TCS operates in combination with the ABS ⇒page 149, “Antilock brake system (ABS)*”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light ⇒page 26 lights up in the instrument cluster when there is a fault on the TCS.
Switching off
You can switch the TCS off and on again as you wish by pressing the button ⇒ fig. 146. The TCS warning light ⇒page 26 lights up in the instrument cluster when the TCS is switched off.

The TCS 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.
Examples:
•when driving with snow chains,
•when driving in deep snow or on a loose surface,
•when it is necessary to rock a car free when it has become stuck.
then you should switch on the TCS again.
WARNING
You should always adjust your style of driving to the conditions of the road surface and the traffic situation. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•All four wheels must be fitted with the same tyres in order to achieve problem- free operation of the TCS. Differing rollin g circumferences of the tyres can lead to an undesirable reduction in the engine output.
•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 TCS ⇒page 193, “Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock pr events an individual wheel from
slipping.
Models fitted with ESP are equipped with electronic differential lock (EDL).
General
The EDL makes it much easier, and sometimes at all possible, to start off, accelerate and climb a steep hill when the conditio ns of the road surface are unfavourable.
Operating principle
The EDL is activated automatically, that is without any action on the part of the driver. It monitors the speeds of the driven wheels with the aid of the ABS sensors. Should only one drive wheel begin spinning on a slippery surface there will be an appreciable difference in the speed of the driven wheels. The EDL function brakes the slipping wheel and the differential transmits a greater driving force to the other driven wheel. This control proce ss is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unus ually severe stresses exist in order to avoid excessive heat generation in the disc brake on the wheel which is being braked. The vehicle can continue to be driven and has the same characteristics as a vehicle not fitted with EDL.
The EDL switches on again automatically as soon as the brake has cooled down.
WARNING
•Depress the accelerator carefully when accelerating on uniformly slip- pery road surfaces, such as ice and sn ow. The driven wheels might still spin despite the EDL and affect the stability of the vehicle - risk of an accident!
•You should always adapt your style of driving to the condition of road surface and to the traffic situation even when your vehicle is fitted with EDL. The increased safety offered must not tempt you to take greater risks than otherwise - risk of an accident!
Note
•If the ABS or TCS or ESP warning light comes on, this may also indicate a fault in the EDL. Please have the car inspected as soon as possible by a specialist garage.
•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 EDL ⇒page 193, “Accessories, changes and replacement of parts”.

Brakes
What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions of the vehicle and your style of driving. Particularly if you drive a great deal in towns and over short distances or if you adopt a sporty style of driving, it may be neces- sary to have the thickness of the brake pads inspected at a specialist garage between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain condi- tions such as when driving through water, during heavy rain showers or after the vehicle has been washed in an automatic vehicle wash, since the brake discs and brake pads may be moist or even have a coating of ice on them in winter. You should dry the brakes as soon as possib le (by applying and releasing the brakes several times, if the road conditions and the traffic situation allows it).
There also may be a certain delay before the full braking efficiency is available when driving on roads which have been treated wi th road salt if you have not used the brakes for some considerable time beforeha nd. The layer of salt on the brake discs and brake pads must first be rubb ed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on th e bake pads occur if the vehicle has been parked for a long period and if you do not make much use of the braking system.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly high speed if you do not make much use of the braking system or if surface corro- sion is present ⇒.
Faults in the brake surface
If you notice that the braking distance has suddenly become longer and that the brake pedal can be depressed further, it is possible that a brake circuit of the dual- circuit brake system has failed. Drive, in such cases, to the nearest specialist garage without delay in order to have the problem rectified. Drive at a reduced speed while on your way to the dealer and adapt your style of driving to the higher brake pedal pressure required.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The level of the brake fluid is monitored electronically ⇒page 28, “Brake system ”.
WARNING
•Only apply the brakes for the purpose of drying and cleaning the brake discs if the traffic conditions permit this. Do not place any other road users in jeopardy.
•When retrospectively mounting a front spoiler, solid wheel hubs etc. one must ensure that the air supply to the front wheel brakes is not reduced otherwise the braking sy stem could run too hot.
•Allow for the fact that new brake pads do not achieve their full braking efficiency until approximately 200 kilo metres. New brake pads must be first “run in” before they develop their optimal friction force. You can, however, compensate for this slightly reduced braking force by increasing the pres- sure on the brake pedal. This guidelin e also applies to any new brake pads installed at a future date.
Caution
•Never allow the brakes to ru b by applying slight pressure if you do not wish to brake the vehicle. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.
•Before negotiating a steep downhill section, please reduce your speed and shift down into the next lower gear (manual ge arbox) or select a lower driving stage (automatic gearbox). This enables you to make full use of the braking power of the vehicle and reduces the strain on the brakes . Any additional braking should be done intermittently, not continuously.
Brake booster
The brake booster boosts the pressure which you generate with the brake pedal. The necessary pressure is only gene rated when the engine is running.
