•Blower switch in the desired position,
•Turn the air distribution control into the position ,
•Open air outlet vents 3 and 4 ⇒ page 95, fig. 86
The control dial can be set to other positions as required.
Recirculated air mode
In recirculated air mode air is sucked out of the interior of
the vehicle and then fed back into the interior.
Recirculated air mode prevents polluted air outside the vehicle
from getting into the vehicle, for example when driving through a
tunnel or when standing in a traffic jam.
Switching recirculated air mode on
– Press button , the button symbol
 lights up ⇒page 93,
fig. 85.
Switching recirculated air mode off
– Press button again, the button symbol
 goes out.
The recirculated air mode is switched off automatically if the air distribu-
tion control is in position  ⇒ page 93, fig. 85 .
WARNING
You should not leave recirculated air mode on over a longer period
of time. “Stale air” may result in fatigue in the driver and passen-
gers, reduce attention levels and also cause the windows to mist
up. The risk of having an accident increases. Switch recirculated
air mode off as soon as the windows begin misting up.

You can set the air supply to the individual vents with the air distribution
control ⇒page 97, fig. 87 . Air outlet vents 3 and 4 can also be opened
or closed individually.
Unwarmed or cooled air will flow out of the air outlet vents according to the
setting of control dial ⇒page 97, fig. 87 and the atmospheric
conditions.
Using the air conditioning system economically
The compressor on the air conditioning system uses power from the
engine when in cooling mode which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which
the interior has been strongly heated through the effect of direct sunlight
in order to allow the heated air to escape.
The air conditioning system should not be switched on while travelling
when the window is open.
The desired interior temperature can also be achieved without switching
in the air conditioning system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.
Operational problems
If the cooling system does not operate at outside temperatures higher
than +5°C, there is a problem in the system. The reasons for this may be:
•The fuse on the air conditioning system has blown. Check the fuse,
replace it if necessary ⇒page 232.

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 depress the brake pedal first and press the Shiftlock
button at the same time in order to move the selector lever out of these
positions. The following will be displayed in the information display*:
P LOCKED (P locked)
or
N LOCKED (N locked)
Symbol
 also lights up in the selector lever cover until the brake pedal
is actuated.
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.
Kickdown function
The kickdown function provides you with maximum accel-
eration power.
Depressing the accelerator pedal beyond the pressure point casues the
automatic gearbox to shift down into a lower gear (in line with vehicle
speed and engine speed). The gearbox shifts up into the next higher gear
when the engine has reached its maximum revolutions.
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 operating the kickdown func-
tion, will cause the gearbox to switch over to the sporty driving
programme. Shifting up later into a higher gear makes it possible to fully
exploit the power reserves of the engine. The gearbox also then shifts

anceTechnical DataFabia Praktik
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 140, fig. 116 . 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 144, “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 passenger airbags be deacti-
vated. 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 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.
•No modifications of any kind may be made to parts of the airbag
system. Any work on the airbag system including removing and installing system components because of other repair work (e.g.
removing 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 surface of the front passenger
airbag in the dash panel.
Side airbags*
Description of side airbags
The side airbag increases protection of the passenger
concerned in the case of a side impact.

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 157, fig. 130 . 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 215.
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 161, “Antilock
brake system (ABS)*”. The TCS will not f unction 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 158, fig. 131 . The TCS warning light ⇒page 34 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
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 TCS again.

•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 215, “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

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 TCS or ESP warning li ght comes on, this may also indi-
cate 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

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 specialist garage 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 avail-
able 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
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle
has been parked for a long period and if you do not make much use of the
braking system.
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
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 specialist garage without delay in order to have the problem
rectified. 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.

Operating principle
As soon as the vehicle speed has increased to about 20 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
•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 specialist garage as quickly as possible and
adjust your style of driving to ta ke account of the ABS fault in the
meantime since you will not know how great the damage is.
Note
•A warning light comes on if a fault occurs in the ABS system
⇒ page 35.
•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 ABS
⇒ page 215, “Accessories, changes and replacement of parts”.
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 157.
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.
