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. 119 .
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. 120 .

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. 125 .
The front airbag for the front passenger* is housed in the dash panel
above the storage compartment ⇒fig. 126 . The installation positions are
each marked with the “AIRBAG” logo.
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 “Important safety
information regarding the front airbag system” on page 158.
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
⇒ page 158, fig. 128 . Not maintaining this minimum distance will
mean that the airbag sy stem 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 163, “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 by 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 dash panel on the front
passenger side.

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 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 deactivation of the airbags, you
can deactivate the front passenger airbag or passenger side airbag by
means of this switch ⇒page 164.
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 direction of travel of the
vehicle (in some countries this must be in the direction of travel due to
other legal regulations applying) ⇒page 166, “Important safety informa-
tion 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 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 164, fig. 134 .
Note
Your Škoda Service Partner 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),
•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 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.
The ESP operates in combination with the ABS ⇒page 181, “Antilock
brake system (ABS)*”. If there is a fault in the ABS system, the ESP also
does not operate.

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 36,
“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 system could run too hot.
•Allow for the fact that new brake pads do not achieve their full
braking efficiency until approximately 200 kilometres. New brake
pads must be first “run in” before they develop their optimal fric-
tion force. You can, however, compensate for this slightly reduced
braking force by increasing the pressure on the brake pedal. This
guideline also applies to any new brake pads installed at a future
date.
Caution
•Never allow the brakes to rub 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 gearbox) 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 generated when the engine is
running.
WARNING
•Never switch off the engine before the vehicle is stationary.
•The brake booster only operates when the engine is running.
Greater physical effort for braking is required when engine is
switched off. Because if you do not stop as normal, this can cause
an accident and severe injuries.
Antilock brake system (ABS)*
ABS prevents the wheels locking when braking.
General
The ABS contributes significantly to enhancing the active safety of your
vehicle. Compared to a car not fitted with the ABS brake system, you are
able to retain optimal steering ability even during a full brake application
on a slippery road surface because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter
under all circumstances as a result of the ABS. The braking distance for
example on gravel and fresh snow, when you should anyway be driving
slowly and cautiously, will be longer.

•The increased safety offered by the Brake Assist must not tempt
you to take a greater safety risk than otherwise.
Power steering*
The power steering enables you to steer the vehicle with less physical
force.
The steering characteristics can be changed by a specialist garage.
You will place great stresses on the power steering system if the steering
is turned to full lock when the vehicle is stationary. Turning the steering to
full lock in such a situation will be accompanied by noises.
It is still possible to fully steer the vehicle if the power steering fails or if the
engine is not running (vehicle being towed in). The only difference is that
greater physical effort is required.
It is possible that the hydraulic pump of the power steering will not run due
to the low vehicle network voltage if the battery has gone flat and the
engine must started with the help off jump leads. This condition will be
indicated by lighting up of the warning light.
The power steering operates again if the battery is charged to a specific
range when engine is running. It also operates again, if the engine can be
started with its own battery.
Caution
Do not leave the steering at full lock for more than 15 seconds when the
engine is running - risk of damaging the power steering!
Note
Have the steering inspected as soon as possible by a specialist garage if
there is a leak or fault in the system.
Tyre inflation pressure-control system*
The tyre inflation pressure-control system compares with the aid of the
ABS sensors the speed and also the roll ing circumference of the individual
wheels. If the inflation pressure and therefore the rolling circumference of
a wheel has changed significantly, the warning light
 lights up in the
dash panel ⇒page 34. The tyre inflation pressure-control system func-
tions late or too sensitively if:
•the structure of the tyre is damaged,
•the vehicle is loaded to one side or with a load on the roof,

•the wheels of an axle are loaded heavily (e.g. when towing a trailer or
when driving uphill or downhill),
•the vehicle is operated in unfavourable winter conditions or on an
unfirm ground,
•snow chains or emergency wheel are mounted,
•the driver has a sporty style of driving (with sharp acceleration and
high speed when cornering).
Basic setting of tyre inflation pressure-control system
After changing the tyre inflation pressures or after changing one or several
wheels, the button for the tyre inflation pressure-control system must be
pressed long enough until an acknowledegment tone sounds when the
ignition is switched on.
•Inflate all tyres to the specified inflation pressure ⇒page 226.
•Switch on the ignition.
•Press the button   ⇒ page 183, fig. 147 long enough, until an
acknowledgment tone sounds, which confirms the storage of the basic
values. As long as the button
  is pressed, the warning light lights
up in the instrument .
Function description
After the basic setting of the system the “adaptation” of the tyre inflation
pressures and then the tyre pressure control in the individual tyres are
performed.
Warning light
 lights up
If the tyre inflation pressure of at least one wheel is insufficiently inflated
in comparison to the stored basic value, the warning light
 ⇒ lights
up. Warning light
 lights up and after pressing the button SET it does
not go out.
If the warning light lights up and does not go out after pressing the button
SET there is a fault in the system. Have the vehicle inspected by your
nearest specialist garage.
WARNING
•When the warning light  lights up, immediately reduce the
speed and avoid sudden steering and brake manoeuvres. Please
stop the vehicle without delay at the nearest possible stop and
inspect the tyres and their inflation pressures.
•The driver is responsible for the correct tyre inflation pressures.
For this reason, the tyre inflation pressures must be checked regu-
larly.
•Under certain circumstances (e.g. sporty style of driving, wintry
or unpaved roads) the warning light  can be delayed or does not
light up at all.
•The tyre inflation pressure-control system does not take away
the responsability from the driver for the correct tyre inflation pres-
sure.
Note
The tyre inflation pressure-control system:
•does not replace the regular tyre inflation pressure control, because
the system cannot detect an even pressure loss,
•cannot warn in case of very rapid tyre inflation pressure loss, e.g. in
case of sudden tyre damage. In this case carefully bring the vehicle to a
standstill without sudden steering movements and without sharp
braking.
