Technical Data
When are the airbags deployed?The airbag system is designed in such a way that the driver and the 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* in the front seat and the head
airbag* on the side on which the collision occurs are deployed.
It is also possible under certain special accident situations that the front as well as
the side airbags and head airbags* are deployed at the same time.
The airbags are not deployed in the case of minor frontal and side collisions, in the
case of rear-end collisions 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 against which the vehicle impacts (hard, soft), the angle of impact,
the vehicle speed 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 vehicle 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 is switched off;
•
a minor frontal collision;
•
a minor side collision;
•
a rear-end collision;
•
Rollover of the vehicle.Note
•
A grey white or red, non harmful gas is released when airbag is inflated. This is
perfectly normal and is not an indication 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.

Important safety information on the side airbag
Correct use of the airbag system considerably reduces the risk of
injury!
WARNING
•
It is essential to always switch off ⇒page 145, “Deactivating airbags” 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 also 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 require that the side passenger airbags be
deactivated. When transporting a child on the front passenger seat, please
comply with the appropriate national regulations regarding the use of child
safety seats.
•
Your head should never be positioned in the deployment area of the side
airbag. You might suffer severe injuries in the event of an accident. This
applies in particular to children who are transported without using a suit-
able child safety seat ⇒page 149, “Child safety and side airbag*”.
•
If children adopt an incorrect seated position when travelling, they may
be exposed to an increased risk of injury in the event of an accident. This can
result in serious injuries ⇒page 147, “What you should know about trans-
porting children!”.
•
There must not be any further persons, animals as well as objects posi-
tioned between the occupants and the deployment area of the airbag. No
accessories, such as a can holder, should be attached to the doors.
•
Only hang light items of clothing on the clothes hooks to the vehicle.
Never leave any heavy or sharp-edged objects in the pockets of the items of
clothing.
•
Ensure that there are no excessive forces, such as violent knocks, kicks
etc., impact on the backrests of the seats otherwise the system may be
damaged. The side airbags would not be deployed in such a case!
•
Any seat or protective covers which you fit to the driver or front
passenger seats must only be of the type expressly authorised by Škoda Auto. In view of the fact that the airbag inflates out of the backrest of the
seat, use of non-approved seat or protective covers would considerably
impair the protective function of the side airbag.
•
Any damage to the original seat covers in the area of the side airbag
module must be repaired without delay by your specialist garage.
•
The airbag modules in the front seats must not display any damage,
cracks or deep scratches. It is not permissible to use force in order to open
the modules.
•
Any work on the side airbag system including removing and installing
system components because of other repair work (e.g. removing seats) must
only be carried out by a specialist garage.
Head airbags*Description of the head airbags
The head airbag together with the side airbag offers enhanced occu-
pant protection in the event of a side collision.
WARNING (continued)
Fig. 151 Installation position

s29g.4.book Page 143 Wednesday, June 17, 2009 9:54 AM

Airbag system 144The head airbags are positioned above the doors on both sides in the interior of the
car ⇒fig. 151. The installation positions of the head airbags are each marked with
the “AIRBAG” logo.
The head airbag together with the three-point seat belts and the side airbags, offers
additional protection for the head and neck area of the occupants in the event of a
side collision of major severity ⇒ in “Important safety information on the head
airbag” on page 144.
Apart from their normal protective function, a further task of the seat belts is to
also hold the driver and the occupants in a correct seated position in the event of a
side collision so as to enable the head 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 132.
Together with other elements (such as cross bars in the seats, stable vehicle struc-
ture) the head airbags are the consequent further development of occupant
protection in the case of side collisions.Function of the head airbags
The risk of injury to the head and neck area is reduced in the event of
a side collision by fully inflated head airbags.In the case of a side collision the head airbag is deployed together with the rele-
vant side airbag on the side on which the accident occurs ⇒fig. 152.If the system is deployed, the airbag is filled with propellant gas and covers the
entire area of the side window including the door pillars ⇒fig. 152.
The protection offered by the head airbags is thus available simultaneously both to
the front occupants of the car seated on the side on which the accident occurs, as
well as to the rear occupants. Any impact of the head against par ts of the interior or
objects outside of the car, is cushioned by the inflated head airbag. The reduction
in any impact to the head and the resultant minimizing of any movements of the
head additionally reduce the risk of injuries to the neck area. In certain accident
situations, the front, side and head airbag are simultaneously deployed.
The airbags inflate in fractions of a second and at a high speed in order to be able
to offer that additional protection in the event of an accident. 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.
Important safety information on the head airbag
Correct use of the airbag system considerably reduces the risk of
injury!
WARNING
•
It is essential to always switch off ⇒page 145 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
also 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 require that the side or head passenger airbags be deactivated. When
transporting a child on the front passenger seat, please comply with the
appropriate national regulations regarding the use of child safety seats.
•
There must not be any objects in the deployment area of the head
airbags which might prevent the airbags from inflating properly.
•
Only hang light items of clothing on the clothes hooks to the vehicle.
Never leave any heavy or sharp-edged objects in the pockets of the items of

Technical Data 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 area 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 204.
•
Any work on the head airbag system including installing and removing
system components because of other repair work (e.g. removing headliner)
must only be carried out by a specialist garage.
Deactivating airbagsDeactivating 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 deactivation of the airbags carried out by a
specialist garage.On vehicles equipped with the switch for deactivation of the airbags, you can deac-
tivate the front passenger airbag or passenger side airbag by means of this switch
⇒page 146.
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 is seated with its back to the direction of travel (in some countries
this must be in the direction of travel due to other legal regulations applying)
⇒page 147, “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 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 indicator light in the instrument cluster comes on for about 3
seconds each time the ignition is switched on;
•
if the airbags are switched off, this is indicated in the middle of the dash panel
by the lighting up of the indicator light
  ⇒page 146, fig. 154.
Note
A specialist garage will be able to advise you whether national legislation in your
country allows airbags in your vehicle to be deactivated, and which ones.

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral
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 vehicle 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 vehicle about its vertical axis, the lateral accel-
eration of the vehicle, the braking pressure and the steering angle.
The direction which the driver wishes to take 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 exist, such as the vehicle 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 rear 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 159, “Antilock brake system
(ABS)*”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light lights up in the instrument cluster when there is a fault on the
ESP
 ⇒page 35.
Switching off
You can switch the ESP off and on again as you wish, by pressing the button
⇒fig. 165. The ESP warning light lights up in the instrument cluster when the ESP is
switched off
 ⇒page 35.
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.
Examples:

when driving with snow chains;
•
when driving in deep snow or on a loose surface;
•
when it is necessary to rock a vehicle 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 another combi-
nation of tyres and wheels) can influence the function of the ESP ⇒page 204,
“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 the 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 are spinning, the force transmitted to the road surface is
automatically adapted by reducing the engine speed. This occurs at all speeds.
The TCS operates in combination with the ABS ⇒page 159, “Antilock brake system
(ABS)*”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light lights up in the instrument cluster when there is a fault on the
TCS
 ⇒page 34.
Switching off
You can switch the TCS off and on again as you wish by pressing the button
⇒fig. 166. The TCS warning light lights up in the instrument cluster when the TCS is
switched off

Electronic Differential Lock (EDL)*
The electronic differential lock prevents 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 conditions 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 process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unusually 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
•
Carefully depress the accelerator when accelerating on uniformly slip-
pery road surfaces, such as ice and snow. 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 vehicle inspected as soon as possible by a specialist
garage.
•
Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the EDL ⇒page 204,
“Accessories, changes and replacement of parts”.
