When are the airbags deployed?The airbag system is designed in such a wa
y that the driver and front passenger airbag
are deployed in the event of a
violent frontal collision
.
In the case of a
violent side collision
, the side airbag* on the side of the vehicle at
which the collision occurs, is deployed to
gether with the relevant head airbag*.
In special cases, the front as well as th
e relevant side and head airbags 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 is pl
ayed by factors such as the type of object
against which the vehicle impacts (hard, soft
), the angle of impact, the relative 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 vehicle deceleration which occurs and is measured during the collision remains below the prescribed reference values specified in the control unit, the airbags are no
t 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, non harmful gas is released when airbag is inflated. This is perfectly
normal and is not an indicati
on 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 swit
ch for the interior light is in the door
contact position); − the hazard warning li
ght is switched on;
− all the doors are unlocked; − the fuel supply to the engine is interrupted.
Front airbagsDescription of the front airbags The airbag system is not a su
bstitute for the seat belt!

the “AIRBAG” logo. The front airbag system, in combination with
three-point safety belts, offers additional
protection for the head and chest area of the driver and front passenger in the event of a frontal collision of major severity
⇒page 148.
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

−Always work with an authorised 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 forc
es, 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 dela
y 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.The head airbags are positioned above the door
s on both sides in the interior of the
car
⇒fig. 143
. The installation positions are each marked with the “AIRBAG” logo.
The head airbag together with the three-poin
t seat belts and the side airbags, offers
additional protection for the head and neck ar
ea of the occupants in the event of a side
collision of major severity
⇒page 153.
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 141, “Why seat belts?”.
Together with other elements (such as cross ba
rs in the seats, stable vehicle structure)
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 relevant
side airbag
⇒fig. 144
and the belt tensioner on the side of the car on which the acci-
dent occurs. If the system is deployed, the airbags are filled with propellant gas and extend over the entire area of the side wind
ow including the door pillar
⇒fig. 144
.
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 parts of the interior or objects outside of the car, is cushioned by the in
flated head airbag. The reduction in any
impact to the head and the resultant minimi
zing of any movement
s of the head addi-
tionally reduce the risk of injuries to the neck area. The head airbag also offers addi-tional protection in the case of an offset
impact by covering
the front door pillar.
In certain accident situations, the front, side and head airbag are simultaneously deployed. The airbags inflate in fractions of a second an
d at a high speed in order to be able to
offer that additional protection in the even
t 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 cons
iderably reduces the risk of injury!
WARNING
•
It is essential to always switch off
⇒page 154, “Deactivating an airbag” the
front passenger airbag when attachin
g 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 chil
d is facing the direct
ion of travel). If
this is not done, there is a risk of the ch
ild suffering severe or even fatal injuries
if the front passenger airbag is deploy
ed. 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 clothing.
In addition, it is not permitted 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 installation of loudspeakers). Resulting da
mages 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 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 deploy-
ment area of the head airbags if any obje
cts, 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 acces-
sories fitted may in certain circumstances be thrown into the interior of the car and cause injuries to the occupants
⇒page 221, “Accessories, changes and
replacement of parts”.•
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 an airbagDeactivating 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 protection.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 de
activation of the airbags, you can deacti-
vate the front passenger airbag
by means of this switch
⇒page 154.
Deactivation of airbags is envisaged only for particular instances, such as if:•
Yo u m u s t i n
exceptional cases
use a child seat on the front passenger seat where
the child is seated with its back to the dire
ction of travel (in some countries this must
be in the direction of travel due to other legal regulations applying)
⇒page 156,
“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 ar
ea 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 al
so 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 li
ghts up for 4 seconds after switching on
the ignition and then flashes for 12 seco
nds afterwards in 2 second intervals.
Front passenger airbags sw
itched off using the switch for front passenger
airbags* in storage compartmen
t on the front passenger side:
•
the airbag indicator light in the instrume
nt cluster comes on for about 4 seconds
each time the igniti

Driving TipsIntelligent TechnologyElectronic stability programme (ESP)*GeneralGeneral The ESP aids you in maintaining control of
your vehicle in situations in which the
vehicle is driving at its dynamic limits, such as
entering a curve fast. The risk of skidding
is reduced and your vehicle thus offers greater driving stability depending on the conditions of the road surface. The system operates at all speeds. The following systems are integrated into the electronic stability programme:•
electronic Differential Lock (EDL),
•
traction control system (TCS),
•
active driver-steering recommendation (DSR),
•
antilock brake system (ABS),
•
brake Assist,
•
uphill-Start off-Assist.
The ESP system cannot be switched off, the
TCS system can only be switched off by
pressing the button
⇒fig. 154
, then the ESP warning light flashes slowly
.
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 proc- esses additional measurement data which are supplied by highly sensitive sensors: the rotational velocity of the vehicle about its ve
rtical axis, the lateral acceleration 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 co
nstantly compared with the actual behav-
iour of the vehicle. If
differences exist, such as the vehi
cle beginning to skid, the ESP will
automatically brake the appropriate wheel. The car is stabilised again by the forces wh
ich 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 wh
eel of a vehicle whic
h tends to understeer
(tendency to shift out of the curve). This braking control cycle is accompanied by noises. During an intervention of the system, the warning light
 flashes quickly in the instru-
ment cluster
⇒page 35.
The ESP operates in combination with the ABS
⇒page 167, “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 inst
rument cluster when there is a fault on the
ESP
 ⇒page 35.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 surfac
e and the traffic situation. This partic-
ularly applies when driving on slippery
and wet roads. The increased safety

offered must not tempt you to take greater risks than otherwise - risk of an acci- dent!
Note
•
All four wheels must be fitted with the same tyres in order to achieve problem-free
operation of the ESP. Differing rolling circum
ferences of the tyres can lead to an unde-
sirable reduction in the engine output.•
Changes to vehicle (e.g. on engine, on th
e brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the ESP
⇒page 221, “Accesso-
ries, changes and replacement of parts”.Electronic Differential Lock (EDL)* The electronic differential lock prev
ents an individual wheel from slip-
ping.Models fitted with ESP ar
e 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 automaticall
y, 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 greate
r driving force to the other driven wheel.
This control process is also accompanied by noises. Overheating of the brakes The EDL switches off automatica
lly 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.
EDL Off-road* After switching on the Off-road mode
⇒page 170, EDL Off-road is activated.
EDL Off-road is matched in such a way that it assists the traction of the vehicle when driving on an unfirm ground. EDL is activated earlier in the Off-road mode than in the normal mode. The brake pres- sure builts up more quickly on the slipping
wheel, on one axle, as well as diagonally.
WARNING
•
Carefully depress the accelerator when
accelerating on uniformly slippery
road surfaces, such as ice and snow. Th
e 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 vehicle inspected as soon
as possible by a specialist garage.
•
Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combina-
tion of tyres and wheels) can influence the function of the EDL
⇒page 221, “Accesso-
ries, 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

climb a steep hill when th
e 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 are spinning, the force transmitted to the road surface is auto- matically adapted by reducing the engine speed. The system operates at all speeds. The TCS operates in combination with the ABS
⇒page 167, “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 instru
ment cluster when there is a fault on the
TCS
 ⇒page 34.
During an intervention of the system, the TCS warning light
 flashes quickly in the
instrument cluster
⇒page 34.
Switching off You can switch the TCS off and on again as yo
u wish. On vehicles fitted with ABS, you
can switch off the TCS by pressing the button
⇒fig. 155
, on vehicles fi
tted with ESP*,
you can switch off the TCS wi
th the aid of the button
⇒page 163, fig. 154
. The TCS
warning light
 flashes slowly in the instrument cluster if the system is switched off
⇒ page 34. 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 vehicle when it has become stuck.
Then you should switch on the TCS again. TCS Off-road* After switching on the Off-road mode
⇒page 170, TCS Off-road is activated.
TCS Off-road provides a more effective a
cceleration of the vehicle on an unfirm
ground, as it allows higher traction be
tween the slipping wheels and the ground.
The system operates when starting off or at low speeds.
