•In the event of a side collision, the side airbags will not function properly,
if the sensors cannot measure the increasing air pressure inside the doors,
because the air can escape through lar ge, non-sealed openings in the door
panel.
−Never drive with removed inner door panels.
− Never drive, if parts of the inner door panel have been removed and
the remaining openings have not been properly sealed.
− Never drive, if the loud speakers in the doors have been removed, only
if the loudspeaker openings have been properly sealed.
− Always make sure that the openings are covered or filled, if additional
loudspeakers or other equipment parts are installed in the inner door
panels.
− Always work with a Škoda dealer or have it carried out by a competent
specialist workshop.
•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 authorized 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 repa ir 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 ev ent of a side collision.
The head airbags are positioned above the doors on both sides in the interior of the
car ⇒fig. 170 . The installation positions are each marked with the “AIRBAG” logo.
The head airbag together with the three-po int 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 170.
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 158, “Why
seat belts?”.
Together with other elements (such as cros s bars in the seats, stable vehicle struc-
ture) the head airbags are the conseque nt 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 of th e car on which the accident occurs ⇒fig. 171 .
If the head airbag is deployed, the airbag is filled with propellant gas and extends
over the entire area of the side window including the door pillars ⇒fig. 171 .
The protection offered by the head airbags is thus available simultaneously both to
the front occupants of the car seated on th e side on which the accident occurs, as
well as to the rear occupants. Any impact of the head against parts 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 result ant minimizing of any movements of the
head additionally reduce the risk of injuries to the neck area. The head airbag also
offers additional protection in the case of an offset impact by covering the front
door pillar. In certain accident situations
both the front airbags as well as the side and head
airbags may be deployed together.
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 infl ated. 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 171, “Deactivating an airbag”
the front passenger airbag when attach ing 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 transporting a child on the front passenger
seat, please comply with the appropri ate 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 sh arp-edged objects in the pockets of the items of
clothing. In addition, it is not permit ted to use clothes hangers for hanging
up items of clothing.
•The airbag control unit operates together with the sensors, which are
attached in the front doors. For this reason no adjustments must be carried
out at the doors as well as at the door panels (for example additional instal-
lation of loudspeakers). Resulting dama ges can have a negative affect on the
operation of the airbag system. All work on the front doors and their panels
must only be carried out by a specialist garage.

•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 229, “Accessories,
changes and replacement of parts”.
•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 deactivation of the airbags, you can deac-
tivate the front and side passenger airbag by means of this switch ⇒page 172. 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 173, “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 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 switched 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 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 172, fig. 173 .
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.

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),
•Driver-steering recommendation,
•Antilock brake system (ABS),
•Brake Assist,
•Uphill-Start off-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 185, “Antilock brake system
(ABS)”. If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light ⇒page 32 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. 184 . The ESP warning light ⇒page 32 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.
Examples:

•when driving with snow chains
•when driving in deep snow or on a loose surface
•when it is necessary to rock a ca r 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 229,
“Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDS)*
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 proces s 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
•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 ESP warning light comes on, this may also indicate a fault in the
EDL. Please have the car inspected as s oon 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 229,
“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 conditio ns 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 are spinning, the force transmitted to the road surface is
automatically adapted by redu cing the engine speed. This occurs at all speeds.
The TCS operates in combination with the ABS ⇒page 185, “Antilock brake system
(ABS)”. The TCS will not function if a fault exists in the ABS system.
The TCS warning light ⇒page 31 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. 185 . The TCS warning light ⇒page 31 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 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 in fluence the function of the TCS ⇒page 229,
“Accessories, changes and replacement of parts”.
Driver-steering recommendation*
The driver-steering recommendation is an additional function of the electronic
stability programme (ESP). This function indicates to the driver in critical situations
by means of slight steering wheel impulses the direction evaluated by the system,
in which the vehicle must be steered, so that it stabilizes. The driver-steering
recommendation is active when braking shar ply on different road surfaces and on
the right and left vehicle side.

WARNING
Even with this additional function the vehicle cannot be steered automati-
cally! The driver is furthermore fully reponsible for the steering of the
vehicle!
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 32, “Brake system ”.
WARNING
•Only apply the brakes for the purpos e 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 sect ion, please reduce your speed, 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
