Rear parking aid*
The parking aid provides a warning of obstacles behind
the vehicle.
The audible parking aid determines the distance between the rear bumper
and an obstacle located behind the vehicle with the aid of ultrasound
sensors. The sensors are integrated in the rear bumper.
Range of sensors
The clearance warning begins at a distance of about 160 cm from the
obstacle (area ⇒ fig. 132). The interval between the warning signals
becomes shorter as the clearance is reduced.
A continuous tone sounds from a clearance of just 30 cm (Bereich ) -
danger area. You should not reverse any further after this signal
sounds!
For particular model versions, the distance to the obstruction is also
displayed on the display of the radio. You can also switch off this function
- see operating instructions for radio Activating
The parking aid is activated automatically when
reverse gear is engaged
and the ignition is turned on. This is confirmed by a brief acknowledge-
ment signal.
Deactivating
The parking aid is deactivated by removing the reverse gear.
WARNING
•The parking aid is not a substitute for the driver paying proper
attention and it is always the driver's responsibility to take care
when parking the vehicle or carrying out similar manoeuvres.
•You should therefore satisfy yourself, before reversing, that
there is no small obstacle, such as a rock, thin post, trailer drawbar
etc., behind your vehicle. Such an obstacle might not be within the
range detected by the sensors.
Note
•The parking aid does not operate if you are towing a trailer (applies to
models which feature a factory-fitted towing device*).
•If a warning signal sounds for about 3 seconds after switching the igni-
tion on and engaging reverse gear, and there is no obstacle close to your
car, this indicates a system fault. Have the fault rectified by a specialist
workshop.
•The sensors must be kept clean and free of ice to enable the parking
aid to operate properly.
•If the parking aid is activated and the selector lever of the automatic
gearbox is in the position , warning signal indicates interruption (vehicle
can no longer move).

Front and rear parking aid*
The parking aid provides a warning of obstacles in front
and behind the vehicle.
The audible parking aid determines the distance between the front or rear
bumper and an obstacle with the aid of ultrasound sensors. The sensors
are integrated in the front and rear bumper. The signal tones for the front
parking aid sound higher than for the rear parking aid.
Range of sensors
The distance warning begins at a distance of about 120 cm from the
obstacle in front of the vehicle (area ⇒fig. 134 ) and about 160 cm from
the obstacle behind the vehicle (area ⇒page 144, fig. 132 ). The
interval between the warning signals becomes shorter as the clearance is
reduced.
A continuous tone sounds from a clearance of just 30 cm (Bereich ) -
danger area. You should not reverse any further after this signal
sounds!
Your vehicle can be equipped with a radio which shows on its display the
distance of the vehicle to the obstacle. You can also switch off this func-
tion - see operating instructions for radio
Activating
The parking aid is activated when the reverse gear is engaged and the
ignition is turned on or by pressing the button ⇒fig. 133 - the symbol

lights up in the button. The activation is confirmed by a brief acknowledge-
ment signal.
Deactivating
The parking aid is deactivated after pressing the button
 ⇒ fig. 133 or at
a speed of more than 15 km/h - the symbol  in the button is no longer
illuminated.
WARNING
•The parking aid is not a substitute for the driver paying proper

•You should therefore satisfy yourself, before reversing, that
there is no small obstacle, such as a rock, thin post, trailer drawbar
etc., in front or behind your vehicle. Such an obstacle might not be
within the range detected by the sensors.
Caution
In order to ensure the correct functioning of the parking aid, only a licence
plate frame approved by the manufacturer Škoda for your vehicle type
should be installed at the front bumper. Un-approved licence plate frames
can project into the detection range ⇒page 145, fig. 134 . A non-proved
licence plate frame could be recognized as an obstacle by the system and
this would lead to an incorrect warning. If you have any questions, please
contact a specialist garage.
Note
•Only the front parking aid operates if you are towing a trailer (applies
only to models which feature a factory-fitted towing device*).
•If a warning signal sounds for about 3 seconds after activating the
system and there is no obstacle close to your car, this indicates a system
fault. The fault is confirmed additionally when the symbol
 flashes in the
button ⇒page 145, fig. 133 . Have the fault rectified by a specialist work-
shop.
•The sensors must be kept clean and free of ice to enable the parking
aid to operate properly.
•If the parking aid is activated and the selector lever of the automatic
gearbox is in the position , warning signal indicates interruption (vehicle
can no longer move).
Cruise control system (CCS)*
Introduction
The cruise control system (CCS) maintains a constant speed, more than
30 km/h (20 mph), once it has been set, without you having to depress the
accelerator pedal. This is only possible within the range which is permitted
by the power output and braking power of the engine. The cruise control
system makes it possible - particularly on long journeys - for you to rest
your “accelerator foot”.
WARNING
•The cruise control system must not, for safety reasons, be used
in dense traffic or on unfavourable road surfaces (such as icy
roads, slippery roads or loose chippings) - risk of accident!
•In order to prevent unintentional use of the cruise control
system, always switch off the system after use.
Note
•Models fitted with a manual gearbox: Always depress the clutch pedal
if you switch on the cruise control system when the gearbox is in Neutral.
Otherwise the engine can rev up unintentionally.
•The cruise control system is not able to maintain a constant speed
when driving on steep downhill sections. The weight of the vehicle
increases the speed at which it travels. One should shift down in good
time to a lower gear or slow the vehicle down by applying the foot brake.
•It is not possible on vehicles fitted with an automatic gearbox to switch
on the cruise control system if the selector lever is in the position P, N or
R .

Airbag system
196
In certain accident situations both the front airbags as well as the head
and side airbags may be deployed together.
If an airbag is deployed, the airbag is filled with propellant gas. 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 inflated. This is
perfectly normal and is not an indication of a fire in the vehicle.
The load of the occupants is cushioned when plunging into the fully
inflated airbag and the risk of injury to the entire upper body (chest,
stomach and pelvis) is reduced on the side facing the door.
Important safety information on the side airbag
Correct use of the airbag system considerably reduces the
risk of injury!
WARNING
•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 appropriate national regulations regarding
the use of child safety seats.
•Your head should never be positioned in the deployment area of
the side airbag. You might suffer severe injuries in the event of an accident. This applies in particular to children who are transported
without using a suitable child safety seat
⇒page 205, “Child safety
and side airbags*”.
•If children adopt an incorrect seated position when travelling,
they may be exposed to an increased risk of injury in the event of
an accident. This can result in serious injuries ⇒page 202, “What
you should know about transporting children!”.
•There must not be any further persons, animals as well as
objects positioned between the occupants and the deployment
area of the airbag. There must also be no accessories such as cup
holders, attached to the doors to enable the side airbags to activate
properly.
•The airbag control unit operates together with the pressure
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 damages 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.
•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 large, 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 loudspeakers in the doors have been
removed, only if the loudspeaker openings have been properly
sealed.

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 prop-
erly.
•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 adjust-
ments must be carried out at the doors as well as at the door panels
(for example additional installation of loudspeakers). Resulting
damages 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 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 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 inju- ries to the occupants
⇒page 270, “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 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 and side passenger airbag by means of this
switch ⇒page 200.
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

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.
Fig. 180 ESP switch
s24s.book Page 213 Thursday, November 24, 2005 12:27 PM

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

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
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 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!
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 soon as possible by a
specialist garage.
•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 270, “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 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-
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 218, “Antilock
brake system (ABS)”. The TCS will not function if a fault exists in the ABS
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 rolling circumference of the individual
wheels. If the rolling circumference of a wheel is changed, the warning
light
 lights up in the dash panel insert ⇒page 38. The rolling circumfer-
ence of the tyre can change if:
•the tyre inflation pressure is too low,
•the structure of the tyre is damaged,
•the vehicle is loaded on one side,
•the wheels of an axle are loaded heavily (e.g. when towing a trailer or
when driving uphill or downhill),
•snow chains are mounted,
•the temporary spare wheel is mounted,
•one wheel per axle was changed. 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 264.
•Switch on the ignition.
•Press the button   ⇒ fig. 182 long enough, until an acknowledg-
ment tone sounds, which confirms the storage of the basic values. As long
as the button
  is pressed, the warning light lights up in the instru-
ment .
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

up.
Warning light
 flashes
If the warning light flashes, there is a system fault. 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
