WARNING (Continued)
■ If you notice that the lock is not properly engaged while driving, stop the ve-
hicle immediately and close the bonnet - risk of an accident!
■ Keep children clear of the engine compartment.
■ Do not touch any hot engine parts - risk of burns!
■ Never spill fluids on the hot engine. Such fluids (e.g. the antifreeze con-
tained in the coolant) may ignite!
■ Avoid short circuits in the electrical system - particularly on the vehicle's
battery.
■ Never touch the radiator fan while the engine is still warm. The fan might
suddenly start running! ■ Never open the end cover of the coolant expansion reservoir while the en-
gine is still warm. The cooling system is pressurized!
■ When opening the end cover of the coolant expansion reservoir, cover it
with a cloth to protect your face, hands and arms from hot steam or hot cool-
ant.
■ Do not leave any items such as cloths or tools in the engine compartment.
■ If you wish to work under the vehicle, you must secure the vehicle from roll-
ing away and support it with suitable supporting blocks: the car jack is not
sufficient for this - risk of injury!
■ If any inspection work has to be carried out when the engine is running,
there is an additional risk from rotating parts (e.g. V-belt, alternator, radiator
fan) and the high-voltage ignition system. The following must also be ob-
served: ■Never touch the electric wiring on the ignition system.
■ Always make sure that no jewellery, loose clothing or long hair can get
caught in rotating engine parts - hazard! Always remove any jewellery, tie
back long hair and wear tight fitting clothing before completing any work.
■ Additionally, the following warning instructions must be observed if work
has to be carried out on the fuel or electrical system. ■Always disconnect the vehicle battery from the electrical system.
■ Do not smoke.
■ Never work near open flames.
■ Always have a functioning fire extinguisher nearby. CAUTION
■ Always top up using the correct specification of fluids. This may result in major
operating problems and also vehicle damage!
■ Never open the bonnet using the locking lever - danger of causing damage. For the sake of the environment
In view of the environmentally friendly disposal of fluids, the specials tools and
knowledge required for such work, we recommend that fluids are changed by a
Škoda
Service Partner as part of the inspection service. Note
■ If you have any questions regarding the fluids, visit a
ŠKODA Service Partner.
■ Fluids with the correct specifications can be purchased from ŠKODA Original Ac-
cessories. Ð

Inspecting and replenishing

Radiator fan
First read and observe the introductory information and safety warn-
ings on page 158.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
After switching off the ignition, the radiator fan can intermittently continue to op-
erate for approx. 10 minutes.
ÐChecking the brake fluid
Fig. 136
Engine compartment: Brake fluid
reservoir
First read and observe the introductory information and safety warn-
ings on page 158.
The brake fluid reservoir is located in the engine compartment.
›
Switch off the engine.
› Open the bonnet
» page 160.
› Check the level of brake fluid in the reservoir
» Fig. 136. The level must be be-
tween the “MIN” and “MAX” markings.
When driving, a slight drop in the fluid level is caused by the wear-and-tear and
automatic adjustment of the brake pads, and is therefore perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid lev-
el drops significantly within a short time or if it drops below the “MIN” marking. If
the brake fluid level is too low, this is indicated by the warning light  lighting up
in the instrument cluster » page 19, Brake system .
ä
ä WARNING
If the fluid level has dropped below the MIN marking,  do not continue your
journey - risk of accident! Seek help from a
ŠKODA specialist garage.Ð Changing the brake fluid
First read and observe the introductory information and safety warn-
ings on page 158.
Brake fluid absorbs moisture. Over time it therefore absorbs moisture from the
environment. Excessive water in the brake fluid may be the cause of corrosion in
the brake system. The water content also lowers the boiling point of the brake
fluid.
The brake fluid must comply with the following standards or specifications:
› VW 50114;
› FMVSS 116 DOT4. WARNING
Using old brake fluid can result in severe stress on the brakes because of the
formation of vapour bubbles in the brake system. This greatly impairs the
braking efficiency and thus also the safety of your vehicle. CAUTION
Brake fluid damages the paintwork of the vehicle. Ð
ä
164 General Maintenance

Improper handling of the vehicle battery can cause damage. We therefore recom-
mend that any work on the vehicle battery is carried out by a
ŠKODA Service Part-
ner.
There is a risk of injuries, scalding, accidents and burns when carrying out any
work on the battery and on the electrical system. For this reason, it is essential to
comply with the warning instructions stated below and with the general applica-
ble rules of safety. WARNING
■ The battery acid is strongly corrosive and must, therefore, be handled with
the greatest of care. Always wear protective gloves, eye and skin protection
when handling the vehicle battery. Corrosive fumes in the air irritate the air
passages and lead to conjunctivitis and inflammation of the air passages in
the lungs. They corrode tooth enamel. After contact with the skin, the acid
creates deep wounds which take a long time to heal. Repeated contact with
diluted acids causes skin diseases (inflammations, ulcers, slin cracks). Acids
coming into contact with water are diluted accompanied by significant devel-
opment of heat.
■ Do not tilt the battery otherwise battery electrolyte may flow out of the bat-
tery vent openings. Protect the eyes with safety glasses or a shield! There is
the danger of suffering blindness! If any battery electrolyte comes into con-
tact with your eyes, rinse the relevant eye immediately with clear water for
several minutes. Then consult a doctor immediately. ■ Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. If acid was
swallowed, seek immediate medical attention.
■ Keep children away from the vehicle battery.
■ When you charge a battery, hydrogen is released, and a highly explosive gas
mixture is also produced. An explosion can be caused through sparkling over
during unclamping or loosening of the cable plug while the ignition is on.
■ Bridging of the poles will create a short circuit (e.g. through metal objects,
cables). Possible consequences of a short circuit: Melting of lead struts, explo-
sion and burning of the battery, jets of acid spurting out.
■ It is prohibited to work with a naked flame and light, to smoke or to carry
out any activities which produce sparks. Avoid creating sparks when working
with cables and electrical devices. Strong sparking represents a risk of injury. WARNING (Continued)
■ Before carrying out any work on the electrical system, switch off the engine,
the ignition and all of the electrical components and disconnect the negative
terminal (-) on the battery. If you wish to replace a bulb it suffices to switch off
the relevant light.
■ Never charge a frozen or thawed vehicle battery - risk of explosion and
caustic burns! Replace a frozen vehicle battery.
■ Never jump-start vehicle batteries with an electrolyte level that is too low -
risk of explosion and caustic burns!
■ Never use a damaged vehicle battery - risk of explosion! Replace a damaged
vehicle battery immediately. CAUTION
■ The vehicle battery must only be disconnected if the ignition is switched off,
otherwise the vehicle's electrical system (electronic components) can be dam-
aged. When disconnecting the battery from the electrical system, first of all dis-
connect the negative terminal

(-) of the battery. Then disconnect the positive ter-
minal (+).
■ When connecting the battery to the electrical system, first connect the positive
terminal (+) of the battery. Then connect the negative terminal
(-). Under no cir-
cumstances must the battery cables be connected incorrectly - risk of a cable fire.
■ Ensure that battery acid does not come into contact with the bodywork - risk of
damage to the paintwork.
■ Do not place the battery in direct daylight in order to protect the vehicle battery
housing from the effects of ultra-violet light.
■ If the vehicle has not been driven for more than 3 to 4 weeks, the battery will
discharge. This is because certain electrical components consume electricity (e.
g.
control units) also in idle state. Prevent the battery from discharging by discon-
necting the battery's negative terminal or continuously charging the battery with
a very low charging current.
■ If the vehicle is frequently used for making short trips, the vehicle battery will
not have time to charge up sufficiently and may discharge. For the sake of the environment
A vehicle battery that has been removed is a special type of hazardous waste.
These must be disposed of in accordance with national legal regulations. Note
You should replace batteries older than 5 years. Ð
166 General Maintenance

Charging a vehicle battery
First read and observe the introductory information and safety warn-
ings on page 165.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
› Only for “quick-charging”: Disconnect both battery cables (first of all “negative”,
then “positive”).
› Attach the terminal clamps of the charger to the battery terminals (red =
“posi-
tive
”, black = “negative”).
› Only now plug the mains cable of the charger into the power socket and switch
on the device.
› When charging is completed: Switch off the charger and remove the mains ca-
ble from the power socket.
› Only then disconnect the charger's terminal clamps.
› Reconnect the cables to the battery, if necessary (first of all
“positive”, then
“negative
”).
It is not normally necessary to disconnect the cables of the battery if you re-
charge the vehicle battery using low amperages (as for example from a mini-
charger). Refer to the instructions of the charger manufacturer.
A charging current of 0.1 multiple of the total vehicle battery capacity (or lower)
must be used until full charging is achieved.
It is, however, necessary to disconnect both cables before charging the battery
with high amperages, so-called “ quick-charging”.
“Quick-charging” the vehicle battery is dangerous and requires a special charger
and specialist knowledge. We therefore recommend having the quick charging of
vehicle batteries undertaken by a ŠKODA specialist garage.
The vent plugs of the vehicle battery should not be opened for charging. CAUTION
On vehicles with the START/STOP system, the pole terminal of the charger must
not be connected directly to the negative terminal of the vehicle battery, but only
to the engine earth » page 186, Jump-starting in vehicles with the

START-STOP
system . Ð
ä Disconnecting and reconnecting the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 165.
On disconnecting and reconnecting the vehicle battery the following functions
are initially deactivated or are no longer able to operate fault-free.

Data in the multifunction display are deleted. » page 12 Note
We recommend having the vehicle checked by a ŠKODA Service Partner to ensure
the full functionality of all electrical systems. Ð Replacing the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 165.
When replacing a battery, the new vehicle battery must have the same capacity,
voltage, amperage and be the same size. Suitable types of vehicle batteries can
be purchased from a

ŠKODA Service Partner.
We recommend that the battery is replaced by a ŠKODA Service Partner, where
the new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations. Ð

168 General Maintenance

Automatic load deactivation
First read and observe the introductory information and safety warn-
ings on page 165.
An intelligent vehicle power management system automatically takes various
measures at high loads on the vehicle battery to prevent discharging of the bat-
tery: This manifests itself by the following:
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where appropriate large consumers of power, e.g. seat heaters, rear window
heaters, voltage supply to the 12V power socket, have their power limited or in
case of emergency shut off completely. Note
Despite such intervention by the vehicle electric system management, the vehicle
battery may be drained. For example, when the ignition is switched on a long time
with the engine turned off or the side or parking lights are turned on during lon-
ger parking. Driving comfort is not put at risk by any shutting off of consumers.
Often the driver is not aware of it having taken place. Ðä

Inspecting and replenishing

Tyre control display
Fig. 145
Button for setting the tyre infla-
tion pressure control value
First read and observe the introductory information and safety warn-
ings on page 170.
The tyre control display compares the speed and thus the rolling circumference of
the individual wheels with the help of the ABS sensors. If the rolling circumfer-
ence of a wheel is changed, the warning light
 in the instrument clus-
ter » page 24, Tyre control display  and an audible signal sounds.
The rolling circumference of the tyre can change if: › the tyre inflation pressure is too low;
› the structure of the tyre is damaged;
› the vehicle is loaded on one side;
› the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill);
› snow chains are mounted;
› the temporary spare wheel is mounted;
› one wheel per axle was changed.
Basic setting of the system
After changing the tyre inflation pressure, after changing one or several wheels,
the position of a wheel on the vehicle (e.g. exchanging the wheels between the
axles) or when the warning light lights up while driving, a basic setting of the sys-
tem must be carried out as follows:
› Inflate all of the tyres to the specified inflation pressure
» page 171, Service life
of tyres .
› Switch on the ignition.
ä
›
Press and hold the button

  » Fig. 145 for longer than 2
seconds. While
pressing the button, the warning light  illuminates. At the same time the sys-
tem memory is erased and the new calibration is started, which is confirmed
with an audible signal and then the warning light  goes out.
› If the warning light
 does not go out after the basic setting, this indicates a
system fault. Seek help from a ŠKODA specialist garage.
The warning light  is lit
If the tyre inflation pressure of at least one wheel is insufficiently inflated in com-
parison to the stored basic value, the warning light  » lights up.
The warning light  flashes
If the warning light flashes, there is a system fault. Seek help from a

ŠKODA spe-
cialist garage to correct the fault. WARNING
■ When the warning light  illuminates, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Stop the vehicle as soon as
possible and inspect the tyres and their inflation pressure.
■ Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light  can be delayed or does not light up at all.
■ The tyre control display does not absolve the driver of the responsibility to
ensure the correct tyre inflation pressure. For this reason, the tyre inflation
pressure must be checked regularly. Note
■ The tyre control display does therefore not replace the regular tyre inflation
pressure control, as the system cannot detect an even loss of pressure. ■ The tyre control display cannot provide a warning in the event of very rapid tyre
inflation pressure loss, e.g. in the case of sudden tyre damage. In this case care-
fully bring the vehicle to a standstill without sudden steering movements or
sharp braking.
■ To ensure a proper functioning of the tyre control display, it is necessary to re-
peat the basic setting every 10 000 km or once a year. Ð

Wheels and Tyres

Check after driving for 10 minutes
First read and observe the introductory information and safety warn-
ings on page 182.
Check the tyre inflation pressure after driving for 10 minutes!
If the tyre inflation pressure is 1.3 bar or less:
›
 Do not drive the vehicle!
You cannot properly seal with tyre with the break-
down kit.
› Get professional assistance.
If the tyre inflation pressure is 1.3 bar or more:
› Adjust the tyre inflation pressure to the correct value (see inside of fuel filler
cap).
› Continue driving carefully to the nearest ŠKODA specialist garage at a maxi-
mum speed of 80 km/h (50 mph). ÐJump-starting

Introduction
This chapter contains information on the following subjects:
Jump-starting 186
Jump-starting in vehicles with the START-STOP system 186
The battery of another vehicle can be used to jump-start your vehicle if the en-
gine will not start because the battery is flat. Jump-start cables are required for
this purpose.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the battery
supplying the power must not be significantly less than the capacity of the dis-
charged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and in-
sulated terminal clamps. Observe the manufacturer's instructions.
Positive cable - colour coding in the majority of cases is red.
Negative cable - colour coding in the majority of cases is black.
ä WARNING
■ A discharged vehicle battery may already freeze at temperatures just below
0 °C. In case of frozen battery carry out no jump-starting - risk of explosion!
■ Pay attention to the warning instructions relating to working in the engine
compartment » page 158, Engine compartment .
■ The non-insulated parts of the terminal clamps must never make contact
with each other. In addition, the jump-start cable connected to the positive
terminal of the battery must not come into contact with electrically conduct-
ing parts of the vehicle - risk of short circuit! ■ Do not clamp the jump-start cable to the negative terminal of the dis-
charged battery. There is the risk of detonating gas seeping out the battery
being ignited by the strong spark which results from the engine being started.
■ Route the jump-start cables so that they cannot be caught by any rotating
parts in the engine compartment.
■ Do not bend over the battery - risk of caustic burns!
■ The vent screws of the battery cells must be tightened firmly.
■ Keep any sources of ignition (naked flame, smouldering cigarettes, etc.)
away from the battery - risk of an explosion! ■ Never jump-start vehicle batteries with an electrolyte level that is too low -
risk of explosion and caustic burns. Note
■ There must not be any contact between the two vehicles otherwise current
may flow as soon as the negative terminals are connected. ■ The discharged battery must be properly connected to the system of the vehi-
cle. ■ We recommend you buy jump-start cables from a car battery specialist. Ð

Driver of the tow vehicle
›
Release the clutch particularly gently when starting off or depress the accelera-
tor particularly gently if the vehicle is fitted with an automatic gearbox.
› On vehicles with a manual transmission, only push down on the accelerator
pedal once the rope is taught.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
› Switch on the ignition so that the steering wheel is not blocked and so that the
turn signal lights, horn, windscreen wipers and windscreen washer system can
be switched on.
› Take the vehicle out of gear or move the selector lever into position
N if the
vehicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the en-
gine is running. If the engine is not running, significantly more physical force is re-
quired to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught. CAUTION
■ Do not tow start the engine - danger of damaging the engine! On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. The bat-
tery from another vehicle can be used as a jump-start aid » page 185, Jump-start-
ing .
■ If the gearbox of your vehicle no longer contains any oil because of a defect,
your vehicle must only be towed in with the driven wheels raised clear of the
ground, or on a special vehicle transporter or trailer.
■ The vehicle must be transported on a special vehicle or trailer if it is not possible
to tow in the vehicle in the way described or if the towing distance is greater than
50 km. ■ To protect both vehicles when tow-starting or towing, the tow rope should be
elastic. Thus one should only use plastic fibre rope or a rope made out of a simi-
larly elastic material.
■ One should be constantly vigilant not to allow impermissibly high towing forces
or jerky loadings. There is always a risk of excessive stresses and damage result-
ing at the points to which you attach the tow rope or tow bar when you attempt
to tow a vehicle which is not standing on a paved road.
■ Attach the tow rope or the tow bar to the towing eyes or to the detachable ball
head of the towing device » page 187
or » page 188. Note
■ We recommend using a tow rope from
ŠKODA Original Accessories available
from a ŠKODA Service Partner. ■ Towing another vehicle requires a certain amount of practice. Both drivers
should be familiar with the particular points about towing a vehicle. Unskilled
drivers should not attempt to tow in another vehicle or to be towed in. ■ When towing, respect the national legal provisions, especially those which re-
late to the identification of the towing vehicle and the vehicle being towed. ■ The tow rope must not be twisted as it may in certain circumstances result in
the front towing eye being unscrewed out of your vehicle. Ð Front towing eye

■ Never “repair” fuses and also do not replace them with a fuse of a higher am-
perage - 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 specialist
garage if a newly inserted fuse blows again after a short time.
■ When unlocking and locking the cover for the fuse box in the engine compart-
ment, it must be pressed on the sides of the box, otherwise the locking mecha-
nism can be damaged. ■ The cover for the fuse box in the engine compartment must always be applied
correctly. Water can penetrate and cause damage to the vehicle if the cover was
not applied correctly! Note
■ We recommend always carrying replacement fuses in the vehicle. A box of re-
placement fuses can be purchased from
ŠKODA Original Accessories.
■ Multiple fuses may exist for a single power consuming device.
■ Multiple power consuming devices can share a single fuse.
