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!

fied. 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.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake
system. The level of the brake fluid is monitored electronically
⇒page 35.
Caution
•Never allow the brakes to rub by applying slight pressure if you do not
wish to brake the vehicle. This causes the brakes to overheat and can also
result in a longer braking distance and excessive wear.
•Before negotiating a steep downhill section, please reduce your
speed, shift down into the next lower gear (manual gearbox) or select a
lower driving stage (automatic gearbox). This enables you to make full use
of the braking power of the vehicle and reduces the strain on the brakes.
Any additional braking should be done intermittently, not continuously.
Antiblock brake system (ABS)
ABS prevents the wheels locking when braking.
General
The ABS contributes significantly to enhancing the active safety of your
vehicle. Compared to a car not fitted with the ABS brake system, you are
able to retain optimal steering ability even during a full brake application
on a slippery road surface because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter
under all circumstances as a result of the ABS The braking distance for
example on gravel and fresh snow, when you should anyway be driving
slowly and cautiously, will be longer.
Operating principle
As soon as the vehicle speed has increased to about 6 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
•Only apply the brakes for the purpose of drying and cleaning
the brake discs if the traffic conditions permit this. Do not place
any other road users in jeopardy.
•When retrospectively mounting a front spoiler, solid wheel
hubs etc. one must ensure that the air supply to the front wheel
brakes is not reduced otherwise the braking system could run too
hot.
•Allow for the fact that new brake pads do not achieve their full
braking efficiency until approximately 200 kilometres. New brake
pads must be first “run in” before they develop their optimal fric-
tion force. You can, however, compensate for this slightly reduced
braking force by increasing the pressure on the brake pedal. This
guideline also applies to any new brake pads installed at a future
date.

Driving and the Environment
178
For the sake of the environment
Even if the exhaust system is operating properly, a sulphur-like exhaust
odour may be produced under certain operating conditions of the engine.
This depends on the sulphur content of the fuel. It is often sufficient to
refuel with unleaded premium-grade petrol of a different brand or at a
different filling station.
Motoring abroad
General
Other circumstances may exist abroad.
It is also possible, in certain countries, that the Skoda dealership network
has not been established yet. This is the reason why obtaining certain
spare parts may be somewhat complicated and specialist garage
personnel may only be able to make limited repairs. Škoda Auto in the
Czech Republic and relevant importers are happy to provide information
about technical aspects of the vehicle, required maintenance work and
possibilities for getting repairs done.
Unleaded petrol
A vehicle fitted with a catalytic converter must always be refuelled with
unleaded petrol ⇒page 177. The automobile associations can provide
you with information regarding the locations of filling stations which offer
unleaded petrol.
Headlights
The low beam of your headlights is set asymmetrically. It illuminates the
side of the road on which you are driving to a greater extent. If you drive
abroad on the other side of the road, you will dazzle oncoming traffic.
It is necessary in order to avoid dazzling oncoming traffic to stick a sticker
over a certain part of the headlights.
Windscreen wiper stickers are available at Škoda dealers.
Headlights with Xenon lamps are designed for driving in countries with
traffic on the right or on the left. Have this done always at a Škoda dealer.
Note
You can obtain further information regarding masking over or converting
the headlights from your Škoda Dealer.
Avoiding damage to your vehicle
When driving on poor roads and lanes or when driving over kerbstones,
steep ramps etc., you must pay particular attention to ensuring that any
low-slung parts of the vehicle, such as spoiler and exhaust, do not touch
the ground and get damaged.
This particularly applies to models with a lowered suspension (sport
suspension) and also when your vehicle is fully laden.

Saving electricity
Generating electricity costs fuel.
– Switch off electrical components as soon as you no longer
need them.
When the engine is running, the alternator generates and supplies elec-
trical power. The greater the load on the alternator as a result of having a
large number of electrical components switched on, the more fuel will be
consumed for operating the alternator.
Keeping a log of your fuel consumption
If you really wish to keep a close check on your fuel consumption, it is
best to enter the figures in a logbook. This does not take much time but is
a very worthwhile exercise. It enables you to detect any change (positive
and negative) at an early stage and to take any appropriate action.
If you find that your fuel consumption is too high, you should reflect on
how, where and in what conditions you have driven the vehicle since you
last refuelled.
Environmental compatibility
Environmental protection has played a major role in the design, selection
of materials and manufacture of your new Škoda. Particular emphasis has
been paid to a number of aspects, including:
Design measures
•Joints designed to be easily detached
•Simplified disassembly due to the modular structure system
•Improved purity of different classes of materials
•Identification of all plastic parts in accordance with VDA Recommen-
dation 260
•Reduced fuel consumption and exhaust emission CO2
•Minimum fuel leakage during accidents
•Reduced noise
Choice of materials
•Extensive use of recyclable material
•Air conditioning filled with CFC-free refrigerant
•No cadmium
•No asbestos
•Reduction in the “vaporisation” of plastics
Manufacture
•Cavity protection without using solvents
•Solvent-free protection of the vehicle for transportation from the
production plant to the customer
•Use of solvent-free adhesives
•No CFCs used in the production process
•Without use of mercury
•Use of water-soluble paints

Fuses and light bulbs
242
Caution
•Never attempt to “repair” fuses and also do not replace them with a
fuse of a higher amperage - risk of fire! This may also cause damage at
another part of the electrical system.
•Have the electrical system checked as quickly as possible by a Škoda
dealer if a newly inserted fuse blows again after a short time.
Fuse assignment
Certain electrical components are only standard on certain vehicle model
versions or only suppliable as optional equipment for certain models.
