A fault in the ABS
The system is not functioning properly if the warning light
 does not go
out within a few seconds after switching on the ignition, does not light up
at all or lights up while driving. The vehicle will only be braked by the
normal brake system without the effect of the ABS function. Visit a Škoda
dealer as quickly as possible and adjust your style of driving in the mean-
time since you will not know how great the damage is.
Three additional warning tones will sound if there is a major fault in the
ABS.
Further information about ABS ⇒page 173.
A fault in the entire brake system
If the ABS warning light
 comes on together with the brake system
warning light  (handbrake must be released), there is a fault not only in
the ABS but also in another part of the brake system ⇒.
The following text will be displayed in the information display*: STOP BRAKE FAULT SERVICE MANUAL
Electronic Differential Lock (EDL)*
The EDL is a part of the ABS. A fault in the EDL is indicated by the ABS
warning light
 in the instrument cluster. Have the vehicle inspected
without delay by a Škoda dealer. Further information on the EDL
⇒ page 171.
Electronic immobiliser 
Data is compared between the ignition key and the control unit when
switching on the ignition. The indicator light  will light up for a few
seconds when ignition key authorisation is confirmed.
The warning light will start flashing continuously if a non-authorised igni-
tion key (for example the wrong ignition key) has been used. The engine
cannot be started ⇒page 39.
It is only possible to start the engine of the vehicle with a Genuine Škoda
key with the matching code.
Brake system 
The warning light  flashes or comes on if the brake fluid level is too low,
if there is a fault in the ABS or if the handbrake is applied.
If the warning light
 flashes (handbrake is not applied), stop and check
the brake fluid level ⇒.
The following text will be displayed in the information display*: STOP BRAKE FLUID SERVICE MANUAL
If there is a fault in the ABS which also influences the function of the
normal brake system (e.g. distribution of brake pressure), the ABS
warning light
 comes on together with the brake system warning light

Safety
Passive Safety
Driving the safe way
Passive safety measures reduce the risk of injury in acci-
dent situations.
In this section you will find important information, tips and notes on the
subject of passive safety in your vehicle. We have combined everything
here which you should be familiar with, for example, regarding seat belts,
airbags, child seats and safety of children. It is therefore important, in
particular, to comply with the notes and warnings in this section for your
own interest and in the interest of all those travelling with you.
The information provided in this section applies to all models of your type
of vehicle. It is also possible that equipment is described here which does
not necessarily apply to your vehicle.
Requirements for maximum safety
What you have to pay attention to in order to obtain the
maximum protection from the passive safety measures.
It is important that you comply with the following requirements in order to
ensure that the seat belts and the airbag systems offer you and the occu-
pants of your vehicle maximum protection:
•front seats correctly adjusted ⇒page 69, “Front seats”,
•head restraints adjusted to match your body size ⇒page 74,
•seat belts correctly fastened and adjusted ⇒page 141,
•adopting a correct seated position
WARNING
Please do not forget to give the new owner the complete vehicle
documentation, if you sell your vehicle, including the service
schedule and documents relating to the possible deactivation of
airbags.

Seat belts
144
Note
•Smoke is generated when the belt tensioners are deployed. This is not
an indication of a fire in the vehicle.
•It is essential to pay attention to relevant safety regulations if the
vehicle or individual parts of the system are scrapped. Škoda dealers are
familiar with these regulations and will be able to provide you with detailed
information in this respect.
•When disposing of vehicle or parts of the system, it is important to
comply with the national legal requirements.
WARNING
•The service life of seat belts and belt tensioners is 15 years from
the date of manufacture of the vehicle. It is then necessary to have
the seat belts replaced by a Škoda dealer.
•Any work on the system including removal and installation of
system components because of other repair work, must only be
carried out by Škoda Dealer.
•The protective function of the system is only adequate for a
single accident. If the belt tensioners have been deployed, it is then
necessary to replace the entire system.
•The Owner's Manual must also be handed over to the new
owner if the vehicle is sold.

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!

Driving and the Environment181
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Reducing idling
Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at
a level crossing or at traffic lights with a lengthy red phase. Even after just
30 - 40 seconds you will have saved more fuel than that is needed when
you start the engine up again.
If an engine is only idling it takes much longer for it to reach its normal
operating temperature. Wear-and-tear and pollutant emissions, though,
are particularly high in the warming-up phase. This is why you should
drive off right after starting the engine. Do avoid high engine revolutions
at this time, however.
Regular servicing
A poorly tuned engine consumes an unnecessarily high
amount of fuel.
Having your vehicle serviced regularly at a Škoda Dealer enables you to
satisfy one of the requirements for economical motoring even before you
set off on your journey. Keeping your vehicle properly serviced not only
has a positive effect on the safety of your vehicle and maintaining its
value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10%
higher than normal.
The foreseen maintenance work should be undertaken exactly according
to the service plan by a Škoda dealer.
Also check the oil level after refueling. Oil consumption is dependent to
a considerable extent on the load and speed of the engine. Oil consump- tion could be as high as 0.5 litres/1 000 km depending on your style of
driving.
It is quite normal that a new engine has a higher oil consumption at first,
and reaches its lowest level only after a certain running in time. It is there-
fore not possible to correctly assess the oil consumption of a new vehicle
until after you have driven about 5000 km.
For the sake of
the environment
•You can achieve additional improvements in your fuel economy by
using high-lubricity oils.
•Check the ground below your car at regular intervals to detect any
leakages in good time. Please have your vehicle inspected by a Škoda
dealer if you find any stains caused by oil or other fluids on the floor.

Towing a trailer185
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Tyre inflation pressure
Select the tyre inflation pressure on your vehicle for that of “fully laden”,
⇒
page 220. The inflation pressure of the tyres fitted to the trailer adjust
in accordance with the manufacturer's recommendation.
Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see
the traffic behind the trailer with the standard rear-view mirrors. Both exte-
rior mirrors should be attached to folding arms. Adjust the mirrors so that
they provide you with an adequate field of view to the rear.
Headlights
Before starting off with a hitched trailer, also check the setting of the head-
lights. Alter the setting as necessary with the aid of the headlight beam
adjuster ⇒page 58.
Detachable ball head
The ball rod is detachable on vehicles which feature a factory-fitted towing
device. It is stowed together with separate fitting instructions in the spare
wheel well in the luggage compartment of the vehicle.
Further information on the towing device ⇒page 186.
Note
•We recommend that you also have your vehicle inspected between
service intervals if you tow a trailer frequently.
•The handbrake on the towing vehicle must be put on when coupling
and decoupling the trailer.
Driving Tips
Particular caution is required when towing a trailer.
– Do not, as far as possible, drive with your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temperature gauge if the outside temperature is high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and
the trailer is laden. Maintain a particularly low speed if you cannot avoid
driving with this combination.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies
for countries in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination
reduces with increasing speed means that the legally allowed speed
should not be used when there are unfavourable road, weather or wind
conditions, particularly near accident black spots.
You must always reduce your speed immediately as soon as you detect
even just the slightest swaying of the trailer. On no account attempt to
stop the trailer from “swaying” by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake,
apply the brakes gently at first, then brake firmly. This will avoid brake jolts
resulting from the trailer wheels locking. Shift down gears in good time

Fuel199
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and
similar products) in diesel fuel.
It is then necessary to have the
fuel filter drained of water by a Škoda
dealer more often than stated in the service schedule if the quality of the
diesel fuel used is poor.
You can find information on refuelling ⇒page 200, “Refuelling”.
Caution
•Use a fuel complying with the standard. Filling the tank even only once,
which does not comply with the standard, can result in damage to the fuel
system.
•Water which has collected in the fuel filter can result in engine
problems.
Biofuel
Biofuel (methyl ester from rape oil) is manufactured from vegetable oil by
means of a chemical process.
Biofuel does not contain sulphur. This means that no sulphur dioxide
(SO
2) is produced when it is burnt.
The exhaust gases contain less
•carbon monoxide (CO)
•hydrocarbons (HC)
•particles (soot)
than when operating with conventional diesel fuel.
The Biofuel is more biodegradable. When using biofuel pay attention to the following points:
•The
Performance may be reduced slightly if you switch to driving with
biofuel.
•The Fuel consumption may increase slightly if you switch to driving
with biofuel.
Biodiesel conforming to the standard E 51 606 can be mixed in any
desired ratio with diesel fuel conforming to the standard EN 590.
We recommend refuelling with diesel fuel at temperatures below -10°C.
Caution
Filling the tank even only once with biofuel, which does not comply with
the standard standard E 51 606 , can result in damage to the fuel
system.
Operation in winter
Winter-grade diesel fuel
A different grade of diesel fuel is available at filling stations in winter than
during the summer. Using “summer-grade diesel fuel” at temperatures
below 0°C can result in operational problems because the diesel becomes
viscous as a result of paraffin separation.
It is therefore the case that DIN EN 590 prescribes diesel fuel class for
certain periods of the year which can also be purchased at the corre-
sponding time during the year. “Winter-grade diesel fuel” will still operate
properly even at a temperature of -20°C.
It is often the case in countries with different climatic conditions that diesel
fuels available have a different temperature characteristic. Škoda dealers
and filling stations in the country concerned will be able to provide you with
information regarding the diesel fuels available.
