WARNING
■ The brake booster only operates when the engine is running. Greater physi-
cal effort for braking is required when the engine is switched off - risk of acci-
dent!
■ Depress the clutch pedal when stopping or braking a vehicle with a petrol
engine and manual transmission in the low rev range. If you fail to do so, the
functionality of the brake booster can be impaired - risk of accident!
■ If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must be
ensured that the air supply to the front wheel brakes is not reduced. Other-
wise, the functionality of the brake system could be impaired - risk of acci-
dent! ■ Please note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating, which can
have a negative effect on the operation of the brake system - risk of accident!
■ Never leave children unattended in the vehicle. The children might, for ex-
ample, release the handbrake or take the vehicle out of gear. The vehicle
might then move off - risk of accident!
■ A lack of fuel can cause irregular engine running or cause the engine to shut
down. The brake assist systems would then be without function - risk of acci-
dent! ■ Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions. The increased safety offered by the brake assist systems
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 ŠKODA specialist garage immediately and adjust your style of driving
according to the damage to the ABS as you will not know how great the dam-
age is and the limitation it is placing on the braking efficiency. CAUTION
■ Observe the recommendations on the new brake pads » page 139.
■ Never let the brakes slip with light pressure on the pedal if braking is not neces-
sary. This causes the brakes to overheat and can also result in a longer braking
distance and excessive wear.
■ All four wheels must be fitted with the same tyres approved by the manufactur-
er to ensure the brake assist systems operate correctly. Note
■ If the brakes are applied in full and the control unit for the braking system con-
siders the situation to be dangerous for the following traffic, the brake light
flashes automatically. After the speed was reduced below around 10 km/h or the
vehicle was stopped, the brake light stops flashing and the hazard warning light
system switches on. The hazard warning light system is switched off automatical-
ly after accelerating or driving off again. ■ Before negotiating a steep downhill section, reduce the speed, shift down into
the next lower gear (manual gearbox) or select a lower drive position (automatic
gearbox). As a result, the braking effect of the engine will be used, reducing the
load on the brakes. Any additional braking should be completed intermittently,
not continuously. ■ Changes to the vehicle (e.g. to the engine, brakes, chassis or another combina-
tion of tyres and wheels) can influence the functionality of the brake assist sys-
tems »
page 177, Accessories, changes and replacement of parts .
■ If a fault occurs in the ABS system, the ESC, ASR and EDL also do not work. A
warning light  »

page 22 comes on if a fault occurs in the ABS system. Ð Information for braking
First read and observe the introductory information and safety warn-
ings on page 93.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driving
style. The brake pads wear more quickly if a lot of journeys are completed in
towns and over short distances or if a very sporty style of driving is adopted. If
operated under severe conditions, the thickness of the brake pads must be
checked by a ŠKODA specialist garage before the next service appointment.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake pads
may be moist or have a coating of ice or layer of salt on them in winter. The
brakes are cleaned and dried by applying the brakes several times.
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. If the brake system is not used much or if there is corrosion on the sur-
face, we recommend cleaning the brake discs by firmly applying the brakes from a
fairly high speed. £

94 Using the system

WARNING (Continued)
■ The seat belts for the rear seats can only fulfil their function reliably when
the seat backrests are correctly locked into position » page 59, Rear seats.
■ The belt webbing must always be kept clean. Soiled belt webbing may im-
pair proper operation of the inertia reel » page 154, Seat belts.
■ The seat belts must not be removed or changed in any way. Do not attempt
to repair the seat belts yourself.
■ Check the condition of all the seat belts on a regular basis. If any damage to
the seat belts, seat belt connections, inertia reel or the lock is detected, the
relevant seat belt must be replaced by a
ŠKODA specialist garage.
■ Damaged seat belts which have been subjected to stress in an accident and
were therefore stretched, must be replaced - this is best done by a
ŠKODA
specialist garage. The anchorage points for the belts should also be checked. Note
The national legal requirements must be observed when using seat belts. ÐThe physical principle of a frontal collision
Fig. 112
Driver without a fastened seat belt/rear seat passenger without a
fastened seat belt
First read and observe the introductory information and safety warn-
ings on page 125.
The physical principle of a frontal collision can be explained quite simply.
ä As soon as the vehicle is moving, so-called kinetic energy (the energy of motion)
is produced both in terms of the car as well as in terms of the occupants. The
magnitude of this kinetic energy depends essentially on the speed at which the
vehicle is travelling and on the weight of the vehicle including the occupants. The
greater the speed and weight increase, the greater the amount of energy which
has to be absorbed in the event of an accident.
The speed of the vehicle is, nevertheless, the most important factor. Doubling the
speed of the vehicle from 25 km/h up to 50 km/hour increases the kinetic energy
four times.
The common opinion that it is possible to support your body in a minor accident
with your hands, is incorrect. Even in a collision at only a low speed, the forces
acting on the body are such that it is no longer possible to support your body.
Even if you only drive at a speed of 30

km/h to 50 km/h, the forces that your body
is exposed to in the event of an accident can exceed a tonne (1 000 kg).
In the event of a frontal collision, occupants of the car not wearing a seat belt, are
thrown forward and strike in an uncontrolled way parts of the interior of the car,
such as steering wheel, dash panel or windscreen » Fig. 112 - . In certain circum-
stances you could even be thrown out of the vehicle, which could cause life
threatening or even fatal injuries.
It is also important that rear seat occupants fasten their seat belts as they will
otherwise be thrown through the vehicle in an uncontrolled manner in the event
of an accident A rear seat passenger who has not fastened the seat belt is a dan-
ger not only to himself but also for those seated at the front » Fig. 112 - . Ð
126 Safety

■
Also look after the leather dye. Refresh any areas with a special coloured leath-
er cream as required.
■ The leather is a natural material with specific properties. During the use of the
vehicle, minor optical changes can occur on the leather parts of the covers (e. g
wrinkles or creases as a result of the stress of the covers). ÐSeat belts
First read and observe the introductory information and safety warn-
ings on page 148.
Keep the seat belts clean!
Clean dirty seat belts using a mild soapy solution and remove coarse dirt with a
soft brush!
Check the condition of all the seat belts on a regular basis.
Belt webbing which has become severely soiled may prevent the inertia reel from
reeling up the belt properly. WARNING
■ The seat belts must not be removed for cleaning.
■ Never clean the seat belts chemically as chemical cleaning products could
destroy the fabric. The seat belts must also not be allowed to come into con-
tact with corrosive liquids (such as acids etc.).
■ Seat belts which have damage to the webbing, connections, inertia reel or
lock should be replaced by a ŠKODA specialist garage.
■ Inertia reel belts must be completely dried before being reeled up. Ðä
154 General Maintenance

■
Fuels with metallic content may not be used. There is a risk of causing consider-
able damage to parts of the engine or exhaust system!
■ The use of unsuitable fuel additives can cause considerable damage to parts of
the engine or the exhaust system. ÐEthanol E85
Fig. 130
MultiFuel - power socket
First read and observe the introductory information and safety warn-
ings on page 155.
Only valid for vehicles with the 1.6/75°kW MultiFuel engine.
Biofuel Ethanol E85 consists of 85 % bioethanol and 15 % unleaded petrol com-
plying with the standard (DIN) EN°228.
Biofuel Ethanol E85 in accordance with the standard (DIN) EN
228 can be mixed in
any desired ratio with unleaded petrol.
Drive the vehicle for at least 5 minutes without interruption, if biofuel Ethanol
E85 has been refuelled, so that the engine control unit can determine the share
of the biofuel in the fuel. During this period do not drive at top speed of your ve-
hicle or high engine speeds and not at full throttle. During this process decrease
the idling speed.
Operation in winter
If you use biofuel Ethanol E85 at very low temperatures, it is necessary to preheat
the engine before an engine start.
The power socket for the engine preheating is located in the front bumper next
to the fog light » Fig. 130.
ä The outside temperature
Duration of engine preheating
Below -10 °C We recommend up to 1 hour
Below -15 ℃ at least 1 hours.
Below -25 °C at least 2 hours. If an engine preheating is not possible at outside temperatures below -10 °C, the
share of unleaded petrol complying with EN 228 must be as high as possible.
Thus the cold start property of the engine is clearly improved.
If there is biofuel Ethanol E85 in the tank and the engine is not preheated, it can
lead at temperatures below -15 °C to very poor or no starting of the engine. CAUTION
■ Just filling the tank once with diesel fuel that does not comply with the stand-
ard, can cause severe damage to parts of the engine, the fuel and exhaust sys-
tem!
■ If you park the car for a lengthy period, fill with petrol complying with (DIN) EN
°228, because Ethanol E85 can contain low quantities of impurities, which can
lead to corrosion. For the sake of the environment
■ If you use Ethanol E85, the CO
2 emission of your vehicle is lowered up to 5 %.
■ The use of engine preheating at temperatures below -10 °C has a positive effect
on the fuel consumption and thus on the environment. Note
■ When operating with Ethanol E85, the fuel consumption increases by approx 33
%, as a lower quantity of energy is contained in the bioethanol than in unleaded
petrol. ■ Biofuel Ethanol E85 contains only a low quantity of additives in contrast to un-
leaded petrol. Therefore we recommend to fill up the tank with unleaded petrol
complying with EN 228 every 15 000 km (e.g. before the oil change) and run it
empty, so that the engine remains clean.
■ The interval of 15 000 km applies for the oil change.
■ An extension cable used for connecting to the electrical network is located in
the luggage compartment. Ð

Inspecting and replenishing

Changing engine oil
First read and observe the introductory information and safety warn-
ings on page 158.
The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator
» page 10, Service Interval Display.CAUTION
Additives must not be added to the engine oil - risk of causing considerable dam-
age to parts of the engine! Damage, which results from such product, are exclu-
ded from the warranty. Note
If your skin has come into contact with oil, it must be washed thoroughly. ÐCoolant
First read and observe the introductory information and safety warn-
ings on page 158.
The cooling system is filled with a coolant in the factory.
The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture provides antifreeze protection down to -25
°C and also protects the
cooling and heating system from corrosion. It also prevents the formation of scale
and significantly increases the boiling point of the coolant.
The concentration of coolant must therefore not be reduced by adding water dur-
ing the summer months or in countries with a warm climate. The concentration of
coolant additive in the coolant must be at least 40 %. 40 %.
If a higher concentration of antifreeze is required for climatic reasons, the amount
of coolant additive can only be increased up to 60 % (antifreeze protection down
to approx. -40 °C). The antifreeze protection tails off above that concentration.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries the concentration of coolant additive should be at least 50 %.
When refilling, we only recommend you use the same antifreeze written on the
antifreeze expansion tank » Fig. 135 on page 163.

■ Other coolant additives that do not comply with the correct specifications can
above all significantly reduce the anticorrosion effect.
■ Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage! Note
On vehicles that are fitted with an auxiliary heater (auxiliary heating and ventila-
tion), the coolant capacity is approx. 1 l larger. Ð
162 General Maintenance

WARNING (Continued)
place the lifting jack on a solid surface or use a wide and stable base. Use a
non-slip base (e.g. a rubber foot mat) if the surface is smooth, such as cobbled
stones, tiled floor, etc.
■ Never start the engine with the vehicle sitting on the raised jack - danger of
suffering injury.
■ Only attach the lifting jack to the attachment points provided for this pur-
pose. CAUTION
■ The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
■ If the anti-theft wheel bolt is fastened too tightly, it can cause damage to the
anti-theft wheel bolt and adapter. Note
■ The anti-theft wheel bolt set and adapter can be purchased from a ŠKODA Serv-
ice Partner. ■ The national legal requirements must be observed when changing a wheel. ÐPreliminary work
First read and observe the introductory information and safety warn-
ings on page 179.
The following steps must be carried out before actually changing the wheel:
› In the event of a puncture, park the vehicle as far away as possible from the
flow of traffic. The place you choose should be level.
› Let all of the occupants get out.
While changing a tyre, the occupants of the
vehicle should not stand on the road (instead they should remain behind a crash
barrier).
› Switch off the engine and move the gearshift lever into
Neutral or move the
selector lever
for the automatic gearbox into position P .
› Firmly apply the
handbrake.
› If a trailer is connected, remove it.
