•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 .

6-speed automatic gearbox*
Introduction
Your car is equipped with an electronically controlled 6-speed automatic
gearbox. Shifting up and also down through the gears is performed auto-
matically.
At the same time this is a conventional automatic gearbox. The maximum
speed is reached in the 5th gear. The 6th gear serves as an economic
driving programme, which is intended to reduce the fuel consumption.
Information for driving wi th an automatic gearbox
Shifting up and down through the gears is performed auto-
matically.
You can also, however, switch the gearbox over into the
Tiptronic mode . This mode makes it possible for you to also shift
gears manually ⇒ page 153.
Starting-off and Driving
– Depress the brake pedal and hold it depressed.
– Press the Shiftlock button (button in handle of the selector lever), move the selector lever into the desired position, e.g. D
⇒ page 150, and then release the Shiftlock button. – Wait a moment until the gearbox has shifted (a slight engage-
ment nudge can be felt).
– Release the brake pedal and depress the accelerator ⇒.
Stopping for a short time
– The selector lever position N does not have to be selected
when stopping just for a short time, such as at cross roads. It
is sufficient to hold the vehicle stationary using the foot brake.
The engine can, however, be allowed just to idle.
Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector lever to P and then release the Shiftlock button.The engine can only be started when the selector lever is in position P or
N ⇒ page 140.
It is sufficient to engage selector lever position P when parking on a flat
surface. When parking on a slope you should first apply the handbrake
firmly and then move the selector lever into position P. This is to ensure
that there is no excessive pressure acting on the lock mechanism and that
it is easier to subsequently move the selector lever out of position P.
If the selector lever position N is selected by accident while driving it is first
necessary to release pressure on the accelerator pedal and wait for idling
speed of the engine to be reached before engaging a drive position in the
selector lever.

WARNING
•Do not depress the accelerator when changing the position of
the selector lever if the car is stationary and the engine is running
- risk of accident!
•Never move the selector lever into position R or P when driving
- risk of an accident!
•When the engine is running and the vehicle is stationary, it is
necessary to hold the car with the brake pedal in all the positions
of the selector lever (except P and N) since the power transmission
is never completely interrupted, also not when the engine is idling
- the vehicle "creeps".
Selector lever positionsThe selector lever position you have engaged is shown in the information
display of the instrument cluster with the corresponding gear symbol high-
lighted ⇒fig. 137 . In the positions D and S the gear you have engaged will
be additionally displayed on the display.
P - Parklock
The driven wheels are locked mechanically in this position.
The Parklock must only be engaged when the vehicle is stationary ⇒.
If you wish to move the selector lever into or out of this position, you must
press the Shiftlock button in the handle of the selector lever and at the
same time depress the brake pedal.
If the battery is used, the selector lever cannot be moved out of the posi-
tion P ⇒ page 154.
R - Reverse
Reverse gear must only be engaged when the vehicle is stationary and
the engine idling ⇒.

The brake pedal must be depressed and at the same time the Shiftlock
must be pressed, if you wish to obtain the selector lever positions
R, P or
N .
When the ignition is switched on and the selector lever is in position R, the
reverse lights will come on.
N - Neutral
The transmission is in Neutral in this position.
The brake pedal must be depressed (if the lever is in its position for longer
than 2 seconds) in order to move the selector lever out of the position N
into the position D, with the ignition switched on, on a vehicle travelling at
less than 5 km/hour or on a stationary vehicle.
The brake pedal must be depressed (if the lever is in its position for longer
than 2 seconds) in order to move the selector lever out of the position N
into the position R, with the ignition switched on, on a vehicle travelling at
less than 5 km/hour or on a stationary vehicle.
D - Drive, position for driving forward
When the selector lever is in this position, the forward gears are shifted up
and down automatically in line with engine load, vehicle speed and the
dynamic shift programme.
You must depress the brake pedal ⇒ if you wish to move the selector
lever into position D from N when the vehicle is travelling at less than
5 km/hour or is stationary.
In certain circumstances (e.g. when driving in mountainous regions or
when towing a trailer) it may be beneficial to select the manual shift
programme ⇒page 153 for a short time in order to adapt the gearbox
ratios manually to the driving situations.
S - Position for sporty style of driving
Shifting up later into a higher gear makes it possible to fully exploit the
power potential of the engine. The gearbox also then shifts down at higher
engine speeds as in the position D. The gearbox does not shift into the 6th gear in the position
S, because the
maximum speed is achieved with the 5th gear.
The Shiftlock on the selector lever grip must be pressed when moving the
selector lever out of the position D into the position S.
WARNING
•Never move the selector lever into position R or P when driving
- risk of an accident!
•When the engine is running and the vehicle is stationary, it is
necessary to hold the car with the brake pedal in all the positions
of the selector lever (except P and N) since the power transmission
is never completely interrupted, also not when the engine is idling
- the vehicle "creeps".
•You must on no account unintentionally operate the throttle
(e.g. by hand from the engine compartment) if a drive position is
engaged when the car is stationary. The vehicle would otherwise
immediately start off - also when the handbrake is firmly applied -
risk of an accident!
•You must move the selector lever into position P and firmly
apply the handbrake first before you or any other person opens the
bonnet and starts working on the engine when it is running - risk
of accident! It is also essential to observe all warnings ⇒page 248,
“Working in the engine compartment”.
Selector lever lock
Automatic selector lever lock 
With the ignition on, the selector lever is locked when it is in the positions
P and N. You must first of all depress the brake pedal in order to move the
selector lever out of this position. The warning light

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 postion 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
s24s.book Page 152 Thursday, November 24, 2005 12:27 PM

gear matching the speed of the car and this allows you to accelerate
rapidly (e.g. when overtaking) without having to depress the accelerator
pedal fully into the kickdown range. The original programme will be reac-
tivated to match your particular style of driving once the gearbox has
shifted up again.
When driving in hilly regions, the gears are selected to match uphill and
downhill sections. This avoids the gearbox frequently shifting up and down
when negotiating an uphill stretch. When driving downhill, it is possible to
shift down into the Tiptronic position, in order to exploit the engine brake
torque.
Tiptronic
The Tiptronic allows the driver to also shift gears manually.
Switching over to
manual shifting
– Push the selector lever to the right out of position D . As soon
as the gearbox has switched over, 6 5 4 3 2 1 appears in the
display, with the gear engaged being highlighted.
Shifting up gears
– One-touch forward of the selector lever (in the Tiptronic posi- tion) ⇒fig. 138 .
Shifting down gears
– One-touch back of the selector lever (in the Tiptronic position) .
It is possible to switch over to manual both when the car is stationary and
also when driving.

When you accelerate, the gearbox shifts up automatically in gears 1, 2, 3,
4 and 5 into the next higher gear just before the maximum permissible
engine speed is reached.
If you select a lower gear, the automatic gearbox does not shift down until
there is no risk of the engine overrevving (does not apply to shifting from
2nd to the 1st gear).
If you operate the kickdown function, the gearbox shifts into a lower gear
in line with the vehicle speed and engine speed.
Emergency programme
An emergency programme exists in the event of a fault in
the system.
The gearbox operates in a corresponding emergency programme if there
are functional faults in the gearbox electronics. This is indicated by all of
the segments in the display lighting up or going out.
It is possible to continue to move the selector lever into all the positions.
In the positions D and S the gearbox remains engaged in the 3rd gear. It
is also possible to continue to engage reverse gear in the position R.
The manual shift programme (Tiptronic) is switched off in the emergency
mode.
If the gearbox has switched over to emergency mode, drive to the
nearest specialist garage in order to have the fault rectified.
Selector lever-emergency unlocking
In case of interruption of the power supply (e.g. flat vehicle
battery, defective fuse) or defect of the selector lever lock, the
selector lever can no longer be shifted from the position P in the
normal way and the vehicle can no longer be moved. The
selector lever must be unlocked in case of emergency.
– Apply the handbrake firmly.
– Open the stowage compartment in front centre console* or the front ashtray.
– Carefully pull up the front left and right cover.
– Pull up rear cover.
– Press with a narrow object (e.g. ignition key) the yellow plastic hoop -arrow- to the left.

Introduction
Your car is equipped with an automatic gearbox DSG. The abbreviation
DSG means Direct shift gearbox (Direct shift gearbox).
Two independent clutches are needed for the power transmission
between the engine and the gearbox. These replace the torque converter
of the conventional automatic gearbox. Their shifting is matched in such a
way that there are no jerks when shifting the gear and the power transmis-
sion of the engine to the front wheels is not interrupted.
Information for driving with the automatic gearbox
DSG
Shifting up and down through the gears is performed auto-
matically.
You can also, however, switch the gearbox over into the
Tiptronic mode . This mode makes it possible for you to also shift
gears manually ⇒page 160.
Starting-off and Driving
– Depress the brake pedal and hold it depressed. – Press the Shiftlock button (button in handle of the selector
lever), move the selector lever into the desired position, e.g. D
⇒ page 157, and then release the Shiftlock button.
– Release the brake pedal and depress the accelerator ⇒.
Stopping for a short time
– The selector lever position N does not have to be selected
when stopping just for a short time, such as at cross roads. It
is sufficient to hold the vehicle stationary using the foot brake.
The engine can, however, be allowed just to idle.
Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector lever to P and then release the Shiftlock button.The engine can only be started when the selector lever is in position P or
N ⇒ page 140. At temperatures below -10 °C the engine can only be
started in the selector lever position P.
It is sufficient to engage selector lever position P when parking on a flat
surface. When parking on a slope you should first apply the handbrake
firmly and then move the selector lever into position P. This is to ensure
that there is no excessive pressure acting on the lock mechanism and that
it is easier to subsequently move the selector lever out of position P.
If the selector lever position N is selected by accident while driving it is first
necessary to release pressure on the accelerator pedal and wait for idling

selector lever.
WARNING
•Do not depress the accelerator when changing the position of
the selector lever if the car is stationary and the engine is running
- risk of accident!
•Never move the selector lever into position R or P when driving
- risk of an accident!
•If you are stopping at a hill (downhill section), never try to hold
the car stationary with the gear engaged by means of the “acceler-
ator”, this means by letting the cl utch slip. This can lead to over-
heating of the clutch. If there is a risk of overheating of the clutch
due to overload, the clutch is opened automatically and the vehicle
rolls backward - risk of accident!
•If you must stop at a slope, depress and hold the brake pedal,
so that you can prevent the vehicle from rolling back.
Caution
•The double clutch on the automatic gearbox DSG is equipped with an
overload protection. If you make use of the uphill function on a vehicle
which is stationary or driving slowly uphill, it will result in an increase of
thermal stress of the clutches.
•An overheating of the clutches can be detected by the flashing of the
selector level indicator and the “jerk” of the clutches, finally the clutches
are opened. The power transmission from the engine to the front wheels
is interrupted and as a result of this the vehicle can no longer be driven. If
the clutch opens automatically, depress the brake pedal, wait a few
seconds and only then continue driving.
