Warning symbols on the vehicle battery Symbol Importance
 Always wear eye protection.
 Battery acid is severely caustic. Always wear gloves and eye protec-
tion.
 Keep fire, sparks, open flames and lit cigarettes well clear of the ve-
hicle battery.
 When charging the vehicle battery, a highly explosive gas mixture is
produced.
 Keep children away from the vehicle battery. 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, skin 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. ■ 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. £

Inspecting and replenishing

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 Checking the battery electrolyte level
Fig. 104
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 115.
We recommend you have the electrolyte level checked by a ŠKODA specialist ga-
rage from time to time, especially in the following cases.
› High outside temperatures.
› Long daily drives
› After each charge
» page 117.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 104 , the electrolyte level can be determined by looking at the
change in colour.
Air bubbles can influence the colour of the indicator. For this reason carefully
knock on the indicator before carrying out the check.
› Black colour – electrolyte level is correct.
› Colourless or light yellow colour – electrolyte level too low, the battery must be
replaced. Note
■ The battery electrolyte level is periodically checked by a
ŠKODA Service Partner
as part of the Inspection Service. ■ For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked. ■ Vehicles with a START-STOP system are fitted with a battery control unit for
checking the energy level for the recurring engine start. Ð

116 General Maintenance

Operation in winter
First read and observe the introductory information and safety warn-
ings on page 115.
At low temperatures, the vehicle battery only has part of the initial power output
that it has at normal temperatures.
A discharged vehicle battery may already freeze at temperatures just below 0
°C.
We therefore recommend that you have the battery checked and, if necessary, re-
charged by a ŠKODA Service Partner before the start of the winter.
ÐCharging a vehicle battery
First read and observe the introductory information and safety warn-
ings on page 115.
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”.
ä
ä “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 136, Jump-starting in vehicles with the

START-STOP
system . Ð Disconnecting and reconnecting the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 115.
On disconnecting and reconnecting the vehicle battery the following functions
are initially deactivated or are no longer able to operate fault-free:
Operation Operating measure
Enter radio code number » Radio manual
Setting the clock » page 12
Data in the multifunction display are deleted. » page 11 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 115.
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. £
ä
ä
117
Inspecting and replenishing

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.
ÐAutomatic load deactivation
First read and observe the introductory information and safety warn-
ings on page 115.
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
118 General Maintenance

WARNING
■ The factory-supplied lifting jack is only intended for your model of vehicle.
Under no circumstances attempt to lift heavier vehicles or other loads – risk of
injury!
■ Ensure that the vehicle tool kit is safely secured in the luggage compart-
ment. Note
Ensure that the box is always secured with the strap. ÐChanging a wheel
ä
Introduction
This chapter contains information on the following subjects:
Preliminary work 128
Changing a wheel 129
Subsequent steps 129
Loosening and tightening wheel bolts 130
Raising the vehicle 131
Securing wheels against theft 131
WARNING
■ If you are in flowing traffic, switch on the hazard warning light system and
set up the warning triangle at the prescribed distance! The national legal re-
quirements must be observed. In this way you are not only protecting yourself
but other road users as well.
■ If the wheel is damaged or in the event of a puncture, park the vehicle as far
away as possible from the flow of traffic. Park on as flat and firm a surface as
possible. ■ If the wheel has to be changed on a slope, first of all block the opposite
wheel with a stone or similar object to prevent the vehicle from unexpectedly
rolling away. WARNING (Continued)
■ If the vehicle is subsequently fitted with tyres which are different to those it
was fitted with at the works, follow these guidelines » page 121, New wheels
and tyres.
■ Always raise the vehicle with the doors closed.
■ Never position any body parts, such as arms or legs under the vehicle, while
the vehicle is raised with a lifting jack. ■ Secure the base plate of the lifting jack with suitable means to prevent pos-
sible moving. A soft and slippery ground under the base plate may move the
lifting jack, causing the vehicle to fall down. It is therefore always necessary to
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. Ð Preliminary work
First read and observe the introductory information and safety warn-
ings on page 128.
The following steps must be carried out before actually changing the wheel:
›

ground » page 131 .
› Unscrew the wheel bolts and place them on a clean surface (cloth, paper, etc.).
› Remove the wheel.
› Attach the spare wheel and slightly screw on the wheel bolts.
› Lower the vehicle.
› Alternately tighten the wheel bolts opposite each other using the wheel
wrench (crosswise) and then tighten the anti-theft wheel bolt » page 130.
› Reinstall the wheel trim/wheel trim cap or the caps. Note
■ All bolts must be clean and must turn easily.
■ Under no circumstances grease or oil the wheel bolts!
■ When fitting unidirectional tyres, ensure that the direction of rotation is cor-
rect »
page 121, Unidirectional tyres . ÐSubsequent steps
First read and observe the introductory information and safety warn-
ings on page 128.
The following steps must also be performed after changing the wheel.ä
ä ›
Stow and attach the replaced wheel in the spare wheel well using a special
screw » page 122, Spare wheel.
› Stow the vehicle tool kit in the space provided.
› Check
the tyre pressure
on the installed spare wheel as soon as possible.
› Have the
tightening torque of the wheel bolts checked with a torque wrench
as soon as possible.
› Change the damaged wheel or consult a ŠKODA specialist garage about repair
possibilities. Note
■ If it is determined that the wheel bolts are corroded and difficult to turn when
changing the wheel, the bolts must be replaced before checking the tightening
torque. ■ Drive cautiously and only at a moderate speed until the tightening torque has
been checked. Ð

ä
Introduction
This chapter contains information on the following subjects:
Jump-starting 135
Jump-starting in vehicles with the START-STOP system 136
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
134 Do-it-yourself

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 108, 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 Jump-starting

ä
Introduction
This chapter contains information on the following subjects:
Front towing eye 137
Vehicles with manual transmission can be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
Vehicles with automated transmission can be towed with a tow bar or a tow rope
or with the front wheels raised. If the vehicle is raised at rear, the automatic gear-
box is damaged!
A tow bar is the safest way of towing a vehicle and also minimises any shocks.
Only use a tow rope if a suitable tow bar is not available.
When towing, the following guidelines must be observed.
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 automated transmission.
ä
›
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 automated transmission.
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 134, 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 only to the towing eye » page 137. £
