Correct seated position
Correct seated position for the driver
Correct seated position for the driver is important for safe
and relaxed driving.
For your own safety and to reduce the risk of injury in the event of an acci-
dent, we recommend the following setting:
•Adjust the steering wheel so that the distance between the steering
wheel and your chest is at least 25 cm ⇒fig. 152 .
•Position the driver seat in the forward/back direction so that you are
able to press the pedals with your legs at a slight angle .
•Adjust the backrest so that you are able to reach the highest point of
the steering wheel with your arms at a slight angle.
•Adjust the head restraint so that the top edge of the head restraint is
at the same level as the upper part of your head ⇒fig. 153 .
•Fasten the seat belt correctly ⇒page 186, “How are seat belts correctly
fastened?”.
Manual driver seat adjustment ⇒page 83, “Adjusting the front seats”.

WARNING
•The front seats and the head restraints must always be adjusted
to match the body size of the seat occupant as well as the seat belts
must always be correctly fastened in order to provide an optimal
protection for you and your occupants.
•The driver must maintain a distan ce of at least 25 cm to the
steering wheel ⇒page 179, fig. 152 . Not maintaining this minimum
distance will mean that the airbag system will not be able to prop-
erly protect you - hazard!
•When driving, hold the steering wheel with both hands firmly on
the outer edge in the 9 o'clock and 3 o'clock position. Never hold
the steering wheel firmly in the 12 o'clock position or in another
way (e.g. in the middle of the steering wheel or at the inner steering
wheel edge). In such cases, injuries to the arms, the hands and the
head can occur when the driver airbag is deployed.
•The backrests must not be angled too far back when driving
otherwise this will affect proper operation of the seat belts and of
the airbag system - risk of injury!
•Ensure that there are no objects in the footwell as any objects
may get behind the pedals during a driving or braking manoeuvre.
You would then no longer be able to operate the clutch, to brake or
accelerate.
Correct seated position for the front passenger
The front passenger must maintain a distance of at least
25 cm from the dash panel so that the airbag offers the
greatest possible safety when an airbag is deployed.
For the safety of the front passenger and to reduce the risk of injury in the
event of an accident, we recommend the following setting:
•Adjust the front passenger seat as far as possible to the rear.
•Adjust the head restraint so that the top edge of the head restraint is
at the same level as the upper part of your head ⇒page 179, fig. 153 .
•Fasten the seat belt correctly ⇒page 186, “How are seat belts correctly
fastened?”.
In exceptional cases the front passenger airbag can be deactivated
⇒ page 199, “Deactivating an airbag”.
Manual front passenger adjustment ⇒page 83, “Adjusting the front seats”.
Electrical front passenger seat adjustment ⇒page 84, “Adjusting front
seats electrically*”.
WARNING
•The front seats and the head restraints must always be adjusted
to match the body size of the seat occupant as well as the seat belts
must always be correctly fastened in order to provide an optimal
protection for you and your occupants.
•The front passenger must maintain a distance of at least 25 cm
to the dash panel. Not maintaining this minimum distance will
mean that the airbag system will not be able to properly protect you
- hazard!
•Always keep your feet in the footwell when the car is being
driven - never place your feet on the instrument panel, out of the
window or on the surfaces of the seats. You will be exposed to
increased risk of injury if it becomes necessary to apply the brake
or in the event of an accident. If an airbag is deployed, you may
suffer fatal injuries when adopting an incorrect seated position!
•The backrests must not be angled too far back when driving
otherwise this will affect proper operation of the seat belts and of
the airbag system - risk of injury!

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 accident.
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 uncontrolled way parts of the inte-
rior of the car, such as steering wheel, dash panel, windscreen,
⇒fig. 155 .
The occupants of a vehicle who have not fastened their seat belts may
even be thrown out of the vehicle. This can result in fatal injuries.
It is also important that rear seat occupants fasten their seat belts as they
will otherwise 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 for those seated at the
front ⇒fig. 156 .

Front airbags
Description of the front airbags
The airbag system is not a substitute for the seat belt!
The front airbag for the driver is housed in the steering wheel ⇒fig. 161 .
The front airbag for the front passenger* is housed in the dash panel
above the storage compartment ⇒fig. 162 . The installation positions are
each marked with 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 ⇒ in
“Important safety information regarding the front airbag system” on
page 194.
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 front airbags to offer
the maximum protection.

Important safety informat ion 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 suff er 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. 164 . Not maintaining this minimu m 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 occupant.
•It is essential to always switch off ⇒page 199, “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 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 appropriat e national regulations regarding
the use of child safety seats.
•There must not be any further persons, animals or objects posi-
tioned 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. Th ese 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 including 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 surface of the front passenger
airbag in the dash panel.

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 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.
If the front passenger airbags were switched off using the switch for
front passenger airbags* in stowage compartment 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   ⇒ fig. 170 .
Note
Your Škoda dealer will be able to advise you whether national legislation
in your country allows airbags in your vehicle to be deactivated, and which
ones.

Electronic stability programme (ESP)*
General
General
The ESP aids you maintain control of your vehicle in situations in border-
line 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 indi-
vidual 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 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 constantly compared
with the actual behaviour of the vehicle. If differences exist, 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 rear
wheel of a vehicle which tends to understeer (tendency to shift out of the
curve). This braking control cycle is accompanied by noises.

Intelligent Technology
214
The ESP operates in combination with the ABS ⇒page 218, “Antilock
brake system (ABS)”. If there is a fault in the ABS system, the ESP also
does not operate.
The ESP warning light ⇒page 40 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 ⇒page 213, fig. 180 . The ESP warning light ⇒page 40 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 car free when it has become stuck
then you should switch on the ESP again.
WARNING
It is also not possible for the E SP 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 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 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
assignment of tyres and wheels) can influence the function of the ESP
⇒ page 270, “Accessories, changes and replacement of parts”.
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
