Seat belts
150
– Press the red button in the belt lock ⇒fig. 130. The spring
force causes the tongue of the lock to jump out.
– Guide the belt back with your hand to enable the inertia reel to wind up the belt webbing more easily.
A plastic knob in the belt webbing holds the belt tongue in a position which
is easy to get hold of.
Three-point safety belt for the middle rear seat
Your car is equipped as standard with the three-point seat belt in the
middle rear seat. It is used in the same way as the three-point seat belts
on the left and right (at front and rear). The three-point seat belt for the rear
middle seat must be put on first to allow the pelvic part of the belt to run
between the belt lock for the right three-point seat belt and the backrest,
while avoiding crossing the belt webbing of the right and middle seat belts.
WARNING
The three-point safety belt for the rear middle seat can only fulfil its
function reliably when the backrests are correctly locked into posi-
tion ⇒page 82.
Blocking seat belts
The three-point seat belts for the front passenger and for the rear seats
can be blocked for attaching a child safety seat ⇒page 171, “Attaching
child safety seat”. Blocking the belt in this way ensures that the child seat
is held firmly in position in the car.
WARNING
Never attach a child safety seat on the front passenger seat if the
child is seated with its back facing in direction of travel when the
front passenger airbag is still activated ⇒page 166, “Use of child
safety seats on the front passenger seat”. Risk of severe or even
fatal injuries!
Belt tensioners
Safety for the driver and occupants wearing their seat belts, is enhanced
by the belt tensioners fitted to the inertia reels of the front and rear side
three-point seat belts, in addition to the protection afforded by the airbag
system.
The fastened three-point seat belts are automatically tensioned in the
event of a frontal collision of a certain severity. The rear outside belt
tensioners are also deployed if the seat belt is not fastened.
The belt tensioner is deployed in the event of a frontal collision of major
severity. A powder charge is ignited in the inertia reels during deployment.
The belt webbing is pulled into the inertia reels by a mechanical system
and the belt is tensioned.
Belt tensioners are not activated in the event of minor frontal collisions,
side and rear-end collisions, in the case of a rollover and also not in acci-
dents in which no major forces are produced from the front.
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.

Airbag system153
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
•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 the modules of the system are
replaced before the expiry of the term (e.g. because of an accident),
the new change interval has to be entered in the service brochure.
•If you sell your car, please hand over the complete vehicle docu-
mentation 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.
When are the airbags deployed?
The airbag system is designed in such a way that the driver and the front
passenger airbag are deployed 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 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 grey white, non harmful gas is released when airbag is 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.
•In the event of an accident in which the airbags are deployed:
− The interior lighting comes on (if the switch for the interior light is in
the door contact position)
WARNING (continued)

Intelligent Technology
178
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 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 233, “Accessories, changes and replacement of parts”.
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
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 Škoda dealer without delay in order to have the problem recti-
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.

Driving and the Environment187
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 Schedule 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 5 000 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 trailer191
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Tyre pressure
Select the tyre inflation pressure on your vehicle for that of “fully laden”,
⇒
page 226. 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 192.
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

Fuel205
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 206, “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.

Inspecting and Replenishing211
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Note
The location of the inspection points in the engine compartment of petrol
and diesel engines is practically identical.
Engine oil
Engine oil specifications
The grade of engine oil should be selected in accordance
with precise specifications.
The engine of your vehicle has been factory-filled with a high-grade oil
which you can use throughout the year - except in extreme climatic
regions.
You can mix various oils together with each other when refilling with oil.
This does not, however, apply for models with flexible service intervals
(QG1).
Engine oils are, of course, undergoing continuous further development.
Thus the information stated in this Owner's Manual is only correct at the
time of publication.
Škoda dealers are informed by Škoda Auto about current changes. This
why you should always have engine oil changed by your Škoda dealer. Engine oil specifications for vehicles with fixed service intervals

Engine oil specifications for models with flexible service intervals
(QG1)
Caution
Only the above-mentioned oils may be used on vehicles with flexible
service intervals (QG1). We recommend always refilling with oil of the
same specification since this will maintain the properties of the oil. In
exceptional cases, you must top up only once engine oil complying with
Specification VW 502 00 (only for petrol engines) or Specification VW 505
01 (only for diesel engines) to maximum 0.5 litres. You must not use other
engine oils - risk of engine damage!
