Side airbags
Description of side airbags
The side airbag together with the head airbag offers
enhanced occupant protection in the event of a side colli-
sion.
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 suffer 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 148, fig. 130 . Not maintaining this minimum 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 154 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 countri es 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 nation al 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. These 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.
WARNING (continued)
•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 Škoda
dealer.
•Never place any objects on the surface of the front passenger
airbag in the dash panel.

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 Škoda dealer. On vehicles equipped with the switch for deactivation of the airbags, you
can deactivate the front and side passenger airbag by means of this
switch
⇒page 155.
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 direction of
travel (in some countries this must be in the direction of travel due to other
legal regulations applying) ⇒page 157.
•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 monitored electronically, also
when the airbags have been switched off
An airbag which has been switched off by a Skoda dealer using the
vehicle system tester:
•The warning light for the airbag system lights up for 3 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 compartment on the front passenger
side:
•The airbag indicator light in the instrument cluster comes on for about
3 seconds each time the ignition is switched on.
WARNING (continued)
•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 inju-
ries to the occupants if the head airbag is deployed.
•Installing accessories in the area of the head airbag 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 circum-
stances be thrown into the interior of the car and cause injuries to
the occupants.
•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 Škoda Dealer.

Driving Tips
Intelligent Technology
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 and reduce the engine speed.
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 173. If there is a
fault in the ABS system, the ESP also does not operate.

The ESP warning light ⇒page 34 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 169, fig. 145 . The ESP warning light ⇒page 34 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
to switch the system off only in particular exceptional situations if you
desire wheel slip.
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.
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 226.
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 trans-
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 otherwise - risk of an
accident!

mitted 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 173. The TCS will
not function if a fault exists in the ABS system.
The TCS warning light ⇒page 34 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 ⇒page 170, fig. 146 . The TCS warning light ⇒page 28 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
to switch the system off only in particular exceptional situations if you
desire wheel slip.
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.
The EDL ⇒page 171 is a part of the TCS. THE EDL operates independ-
ently of the TCS (also when the TCS has been switched off using the TCS
button).
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
assignment of tyres and wheels) can influence the function of the TCS
⇒ page 226.
Electronic Differential Lock (EDL)*
The electronic differential lock prevents an individual
wheel from slipping.
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.
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!

Intelligent Technology
172
The EDL switches on again automatically as soon as the brake has cooled
down.
Note
•If the ABS warning light comes on, this may also indicate a fault in the
EDL. Please have the vehicle inspected as soon as possible by a Škoda
dealer.
•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 EDL
⇒ page 226.
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 necessary to have the thickness of the brake pads
inspected at a Škoda Dealer between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under
certain conditions 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
possible (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 with road salt if
you have not used the brakes for some considerable time beforehand.
The layer of salt on the brake discs and brake pads must first be rubbed
off when you apply the brakes.
Corrosion
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 corrosion is present
⇒.
Faults in the brake surface
The brake booster operates using vacuum which is only generated
when the engine is running. This is why you should not drive off with
engine switched off!
The brake pedal has to be depressed with a significantly greater force if
the brake booster is not operating because the vehicle has to be towed or
because there is damage to the brake booster, in order to balance out the
missing brake boosting effect.
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 Škoda dealer without delay in order to have the problem recti-
WARNING
•Depress the accelerator carefully when accelerating on
uniformly slippery 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!

fied. 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 35.
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, 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.
Antiblock 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.
Operating principle
As soon as the vehicle speed has increased to about 6 km/hour an auto-
matic test procedure is conducted during which you will be able to hear a
pumping noise for about 1 second.
The brake pressure will be reduced on a wheel which is rotating at a speed
which is too low for the speed of the vehicle and tending to lock. This
control cycle is noticeable from a pulsating movement of the brake
pedal which is accompanied by noises. This is consciously intended to
provide the driver with the information that the wheels are tending to lock
(ABS control range). You must always keep the brake pedal depressed to
enable the ABS to optimally control the brake application in this braking
range. Never interrupt the application of the brakes!
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.

Brake Assist*
During a severe brake application (e.g. if a hazard exists), the Brake
Assist increases the braking force and thus makes it possible to rapidly
produce the pressure required in the brake system.
The majority of drivers do apply the brakes in good time in dangerous situ-
ations, but do not depress the brake pedal with sufficient pressure. Conse-
quently, it is not possible for the car to achieve its maximum deceleration
and the car covers a greater distance than necessary. The Brake Assist is activated by the very quick operation of the brake
pedal. In such cases, a much greater braking pressure exists than during
a normal brake application. This makes it possible, even with a relatively
low resistance of the brake pedal, to produce an adequate pressure in the
brake system in the shortest possible time, which is required for maximum
deceleration of the car. You must apply the brake pedal firmly and hold it
in this position in order to achieve the shortest possible braking distance.
The Brake Assist is able to help you achieve a shorter braking distance in
emergency situations by rapidly producing the pressure required in the
brake system. It fully exploits the attributes of the ABS. After you release
the brake pedal, the function of the Brake Assist is automatically switched
off and the brakes operate in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP,
the Brake Assist function is also not available. Further information on the
ESP
⇒page 169.
Power steering
Power steering assists the driver in steering the vehicle and reduces the
physical force needed for steering.
WARNING
•The ABS can also not overcome the physical limits of your
vehicle. Please do not forget this, particularly when driving on icy
or wet road surfaces. If the ABS is operating within the control
range, adapt your speed immediately to the conditions of the road
surface and the traffic situation. The increased safety offered by
the ABS must not tempt you to take greater risks than otherwise -
risk of an accident!
•The normal braking system is still fully functional if there is an
ABS fault. Visit a Skoda dealer as quickly as possible and adjust
your style of driving to take account of the ABS fault in the mean-
time since you will not know how great the damage is.
WARNING
•The Brake Assist is also not able to overcome the physical
limits of your car in terms of the braking distance required.
•Adapt your speed to the conditions of the road surface and to
the traffic situation.
•The increased safety offered by the Brake Assist must not
tempt you to take a greater safety risk than otherwise.
