up in the instrument cluster as a reminder for the driver when the selector
lever is in position P and N:
In addition, the symbol
 for the automatic selector lever lock in the shift
gate lights up.
A time delay element ensures that the selector lever is not blocked when
rapidly switching over the position N (e.g. from R to D). This does, for
example, allow one to seesaw out a stuck vehicle. The selector lever lock
will click into place if the lever is in the N position for more than 2 seconds
without the brake pedal being pressed.
The selector lever lock is only active if the vehicle is stationary or moving
at speed of less than 5 km/hour. The lock is switched off automatically into
position N when the car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the handle of selector lever prevents certain
selector lever positions being engaged inadvertently. The selector lever
lock is cancelled when you press the Shiftlock button.
Keylock - Ignition key withdrawal lock
You can only withdraw the ignition key after switching off the ignition if the
selector lever is in position P. If the ignition key is withdrawn, the selector
lever is blocked in position P.
Kickdown function
The kickdown function provides you with maximum accel-
eration power.
Depressing the accelerator pedal allows the kickdown function to be acti-
vated in the desired driving program. This function has precedence over
the driving programme and serves for maximum acceleration of the
vehicle when exploiting the maximum power potential of the engine without taking into account the current selector lever position (
D, S or
Tiptronic ). The gearbox shifts down to one or several gears in line with
the driving state and the vehicle accelerates. The gearbox does not shift
up into the highest gear until the engine has reached its maximum revolu-
tions for this gear range.
WARNING
Please note that using the kickdown function can result in the
driven wheels spinning on a smooth or slippery road surface - risk
of skidding!
Dynamic shift programme
The automatic gearbox of your vehicle is controlled electronically. Shifting
up and down through the gears is performed automatically on the basis of
pre-defined driving programmes.
Adopting a moderate style of driving will cause the gearbox to select the
most economical driving programme. Shifting up into a higher gear as
soon as possible and shifting down as late as possible will have a favour-
able effect on your fuel consumption.
Adopting a sporty style of driving with rapid movements of the acceler-
ator pedal combined with sharp acceleration and frequent changes in
speed, exploiting the top speed of the car or depressing the accelerator
pedal (kickdown function), will cause the gearbox to switch over to this
style of driving and shift down earlier with frequent changes in gears in
comparison to the moderate style of driving.
Selecting the most appropriate driving programme for the particular style
of driving is a continuous process. Irrespective of this it is, however,
possible to switch or shift down into a dynamic shift programme by
depressing the accelerator rapidly. The gearbox shifts down into a lower

Communication
128
Note
The operation of the mobile phone fitted with multi-functional module* is
only possible on certain models of mobile phone. More detailed informa-
tion is available from your Škoda Service Partner.
Universal telephone preinstallation with
voice control*
The voice control is activated according to equipment installed on the
vehicle by pressing the button PTT (push to talk)  on the adapter
⇒ fig. 112 or the button  on the multi-functional module* ⇒page 127.
A phone phonebook is part of the mobile phone preinstallation with voice
control. In the phone phonebook there are 300 free memory locations
available. This phone phonebook can be used in line with the mobile tele-
phone. For vehicles fitted with multi-functional module*, the operation is
performed via the function buttons on the module
⇒page 127.
Furthermore the volume can be changed individually at any time with the
button for setting the radio or on vehicles fitted with multi-functional
module* with function buttons on the steering wheel.
If the system answers with the voice response “ Telephone is not ready”,
please check the operating state of the telephone as follows:
•Is the telephone switched on?
•Is the PIN code entered?
Dialogue
The period, in which the telephone system is ready to receive voice
commands and carry out the voice commands, is called DIALOGUE. The
system gives audible feedback and guides you if necessary through the
relevant functions. You can start or end the dialogue at any time by
pressing the PTT button. You can also end the dialogue with the voice
command CANCEL.
The dialogue is always automatically ended after carrying out an opera-
tion, e.g. after erasing the name from the phonebook.
The dialogue of the incoming call is immediately interrupted and you can
accept the call by pressing the button
.
If a voice command is not detected, the system answers with “ Pardon?”
and a new entry can be performed. After the 3rd error the answer “ Cancel”
is given and the dialogue is ended.
Optimum understanding of the voice commands depends on the
following factors:
•Speak with a normal tone of voice without intonation and excessive
voice pauses.
•Avoid insufficient articulation.
•Close the doors, windows and sliding roof, in order to reduce or stop
disturbing exterior noise.

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.

The ESP warning light ⇒page 35 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 177, fig. 145 . The ESP warning light ⇒page 35 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 232, “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-

The TCS operates in combination with the ABS

system.

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
