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 of the air conditioning system is defective ⇒page 241.
Check the fuse, replace it if necessary.
•The cooling system has switched off automatically for a short time
because the coolant temperature of the engine is too hot.
If you are not able to rectify the operational problem yourself, or if the
cooling capacity decreases, switch the air conditioning system off. Please
contact your Škoda dealer.
Climatronic* (automatic air conditioning)
Description
The Climatronic system is a combination of an automatic heating, fresh air
and cooling system which provides optimal comfort for the occupants of
the car.
The Climatronic maintains a constant temperature fully automatically,
once it has been set. This is achieved by automatically varying the temperature of the outflowing air, the blower stages and the air distribu-
tion. It is not necessary to manually alter the settings. The
automatic
mode ⇒ page 109 ensures maximum wellbeing of the occupants at all
times of the year.
Description of Climatronic system
The Climatronic can only operate if the following conditions are met.
•engine running
•outside temperature above +5 °C,
•the button is not pressed.
If the Climatronic system is switched on, the temperature and air humidity
drops in the vehicle. The wellbeing of the occupants of the car is enhanced
as a result of this particularly at high outside temperatures and a high air
humidity. The system prevents the windows misting up during the cold
season of the year.
It is possible to briefly activate recirculated air mode in order to enhance
the cooling effect ⇒.
The heating effect is dependent upon the coolant temperature, thus full
heat output only occurs when the engine has reached its operating
temperature.
Puddle of water below car
After switching on the air conditioning Condensation from the evaporator
of the air conditioning may drip down and form a puddle below the vehicle.
This is quite normal and not an indication of a leak!
Switching over from degrees Celsius to degrees Fahrenheit and vice
versa
First of all press and hold the button ⇒page 108, fig. 102 and
then press the button . The temperature measuring unit appears

Simultaneous pressing of buttons and can be used to de-acti-
vate or activate this function.
A higher tone is heard when switching on this function, when increasing
the blower speed or when increasing the temperature.
A lower tone is heard when switching off this function, when decreasing
the blower speed or when decreasing the temperature.
Aeration of the vehicle when ignition is switched off*
On models fitted with power sliding/tilting roof with sollar cells, the fresh
air blower is automatically switched over to “solar mode ” if the sun ray's
are sufficient after switching off the ignition. The solar cells on the
sliding/tilting roof deliver power for the fresh air blower. This supplies the
interior of the car with fresh air.
For an optimum ventilation, the air outlet vents 3 and 4 must be opened
⇒ page 112.
The ventilation functions only when the sliding/tilting roof is closed.Note
•If the air conditioning system has not been switched on for a lengthy
period, odours may be produced at the evaporator because of deposits.
Switch the air conditioning system on at least once a month for approxi-
mately 5 minutes at the highest blower stage - also during the cold season
of the year - in order to remove such odours. Also open a window for a
short time.
•We recommend that you do not smoke in the vehicle when the recir-
culating air mode is operating since the smoke which is drawn at the evap-
orator from the interior of the vehicle forms deposits in the evaporator of
the air conditioning system. This produces a permanent odour when the
air conditioning system is operating which can only be eliminated through
considerable effort and expense (replacement of compressor).

WARNING
•For your own safety and that of other road users, ensure that all
the windows are free of ice, snow and misting. Please familiarize
yourself about how to correctly operate the heating and ventilation
systems, how to demist and defrost the windows, as well as with
the cooling mode.
•You should not leave recirculated air mode on over a longer
period of time. “Stale air” may result in fatigue in the driver and
passengers, reduce attention levels and also cause the windows to
mist up. The risk of having an accident increases. Switch recircu-
lated air mode off as soon as the windows begin misting up.

Setting temperature
– Press the button or ⇒page 108, fig. 102 and continue
pressing until the desired temperature is set.
You can set the interior temperature between +18°C (64°F) and +29°C
(86°F). The interior temperature is regulated automatically within this
range. If you select the temperature below 18 °C (64 °F), “LO” appears in
the display. If you select the temperature higher than 29°C (86°F), “ HI”
appears in the display. In both limit positions the Climatronic operates at
maximum cooling or heating capacity, respectively. The temperature is not
controlled in this case.
Lengthy and uneven distribution of the air flow out of the vents (in partic-
ular at the leg area) and large differences in temperature, for example
when getting out of the vehicle, can result in chills in sensitive persons.
Controlling blower
There are a total of seven blower stages available.
The Climatronic system controls the blower stages automatically
in line with the interior temperature. You can also, however, adapt
the blower stages manually to suit your particular needs.
Setting blower stages
– Press the button or the button to set the blower stage.
The number of dashes in the display ⇒page 108, fig. 102 indicates
the blower stage.
If OFF is shown in the display, this indicates that the Climatronic system
is switched off ⇒ page 112.

WARNING
•If the Climatronic system is swit ched off (OFF), there is no
supply of fresh air from the outside. “Stale air” may result in fatigue
in the driver and passengers, reduce attention levels and also
cause the windows to mist up. The risk of having an accident
increases.
•Do not switch the Climatronic system off for longer than neces-
sary.

Airbag system
146
When are the airbags deployed?
The airbag system is designed in such a way that the driver and the front
passenger airbag are activated in the event of a frontal collision of major
severity.
In the case of a violent side crash , the side airbags on the side of the car
at which the collision occurs, are deployed together with the relevant head
airbag*.
In certain accident situations it is possible that both the front as well as the
side airbags and the relevant head airbag are deployed at the same time. The airbags
are not deployed in the case of minor frontal and side colli-
sions, in the case of rear-end collisions and vehicle rollover.
Deployment factors
It is not possible to state globally which deployment conditions apply to the
airbag system in every situation as the circumstances which exist in the
case of accidents vary greatly. An important role in this case, for example,
is played by factors such as the type of object against which the vehicle
impacts (hard, soft), the angle of impact, the vehicle speed etc.
A decisive factor for the deployment of the airbags is the deceleration
which occurs during a collision. The control unit analyses the nature of the
collision and activates the relevant restraint system. If the vehicle decel-
eration which occurs and is measured during the collision remains below
the prescribed reference values specified in the control unit, the airbags
are not deployed although the vehicle may well suffer severe damage to
the bodywork as a consequence of the accident.
The airbags are not deployed if:
•ignition off
•a minor frontal collision
•a minor side collision
•a rear-end collision
•rollover
Note
•A fine dust is produced when airbag inflated. This is perfectly normal
and is not an indication of a fire in the vehicle.
•The dash panel must be replaced after the front passenger airbag has
been deployed.
WARNING (continued)
•The protective function of the airbag system is sufficient for
only one accident. The airbag system must then be replaced if the
airbag has been deployed.
•The airbag system needs no maintenance during its working
life.
•The service life of the airbag system is 15 years from the date of
manufacture of the vehicle. Have the airbag system replaced by a
Škoda Dealer after this period.
•If you sell your car, please hand over the complete vehicle
documentation to the new owener. Please note that the documents
relating to the possibility of deactivating the front passenger
airbag are also part of the vehicle documents!
•If the vehicle or individual parts of the airbag system are
scrapped, it is essential to observe the relevant safety precautions.
Škoda dealers are familiar with these regulations.
•When disposing of vehicle or parts of the airbag system, it is
important to comply with th e national legal requirements.

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!
