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. Battery acid corrodes 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
development 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 Battery cover

Checking the battery electrolyte level
Fig. 163
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 182.
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 185.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 163, 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
ä Operation in winter
First read and observe the introductory information and safety warn-
ings on page 182.
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.
Ð Charging a vehicle battery
First read and observe the introductory information and safety warn-
ings on page 182.
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”. £

Inspecting and replenishing

“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 204, Jump-starting in vehicles with the

START-STOP
system . ÐDisconnecting and reconnecting the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 182.
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 12Note
We recommend having the vehicle checked by a ŠKODA Service Partner to ensure
the full functionality of all electrical systems. ÐReplacing the vehicle battery
First read and observe the introductory information and safety warn-
ings on page 182.ä
ä 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 Automatic load deactivation
First read and observe the introductory information and safety warn-
ings on page 182.
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. Ð ä

WARNING
■ During the first 500 km, new tyres do not offer optimum grip and appropri-
ate care should therefore be taken when driving - risk of accident!
■ Never drive with damaged tyres - risk of accident!
■ Only use those tyres or wheel rims which have been approved by ŠKODA for
your model of vehicle. Failure to observe this instruction will adversely affect
the road safety of your vehicle - risk of accident!
■ The maximum permissible speed for your tyres must not be exceeded under
any circumstances - risk of an accident resulting from tyre damage and loss of
control of the vehicle.
■ If the inflation pressure is too low, the tyre must perform a higher rolling re-
sistance. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and a tyre blowout. WARNING (Continued)
■ Do not, where possible, replace individual tyres but at least replace them on
both wheels of a given axle at the same time. Always fit the tyres with the
deeper tread depth to the front wheels.
■ Never use tyres if you do not know anything about the condition and age.
■ You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn down.
■ Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience
“aquaplaning” (uncontrolled
movements of the vehicle - “swimming” on a wet road surface).
■ Immediately replace damaged wheel rims or tyres.
■ Do not use summer or winter tyres that are older than 6 years or 4 years re-
spectively.
■ The wheel bolts must be clean and must turn easily. However, they must
never be treated with grease or oil.
■ If the wheel bolts are tightened to a too low tightening torque, the rim can
come loose when the car is moving - risk of accident! A tightening torque
which is too high can damage the bolts and threads and this can result in per-
manent deformation of the contact surfaces on the rim.
■ In case of incorrect treatment of the wheel bolts, the wheel can loosen
when the car is moving - risk of accident!
■ Observe the national legal regulations relating to the use of tyres and snow
chains. CAUTION
■ If a spare wheel is used that is not identical to the fitted tyres, the following
must be observed » page 190, Spare wheel.
■ The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
■ Protect the tyres from contact with oil, grease and fuel.
■ Replace any lost valve caps immediately. For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption. £

Wheels and Tyres

Note
■ We recommend that any work on the wheels or tyres is carried out by a ŠKODA
Service Partner. ■ We recommend that you use wheel rims, tyres, full wheel trims and snow chains
from
ŠKODA Original Accessories. ÐService life of tyres
Fig. 164
Tyre tread with wear indicators/Open fuel filler flap with a table de-
tailing the tyre size and tyre inflation pressure
First read and observe the introductory information and safety warn-
ings on page 187.
Wear indicators
The base of the tread of the tyres has 1.6 mm high wear indicators installed.
These wear indicators are located multiple times depending on the make and are
evenly spaced around the circumference of the tyre » Fig. 164 - . Markings on
the walls of the tyres through the letters

“TWI”, triangular symbols or other sym-
bols identify the position of the wear indicators.
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insuffi-
ciently or over-inflated and this will have an adverse effect on the handling of
your vehicle. Therefore check the tyre pressure, including that of the spare wheel,
at least once a month and also before setting off on a long journey.
ä The tyre inflation pressures for
summer tyres are indicated on the inside of the
fuel filler flap » Fig. 164 - . The inflation pressures for winter tyres are 20

kPa
(0.2 bar) higher than those for summer tyres.
The tyre inflation pressure for tyres of the tyre size 205/50 R17 that are designed
to be used with snow chains, is identical to the tyre inflation pressure for tyres of
the tyre size 225/45 R17.
The tyre pressure should be at the highest pressure specified for your vehicle at
all times. The tyre inflation pressure of the spare wheel R 18 is 420 kPa.
Always check the inflation pressure when the tyres are cold. Do not reduce the
higher pressure of warm tyres. If the load varies greatly, adjust the tyre inflation
pressure accordingly.
Driving style
Fast cornering, sharp acceleration and braking increase the wear of your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences
when driving which may result in an imbalance and which makes themselves felt
through vibration in the steering.
Have the wheels rebalanced after replacing the tyres.
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-and-
tear on the tyres but will also has an adverse effect on vehicle safety. In the
event of any unusual tyre wear, seek assistance from a ŠKODA specialist garage.
Tyre damage
Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angle in order to avoid damage to tyres and wheel
trims.
We recommend checking your tyres and wheel rims for damage (punctures, cuts,
splits and bulges, etc.) on a regular basis. Remove foreign bodies from the tyre
profile.
Unusual vibrations or pulling of the vehicle to one side could be a sign of tyre
damage. If there is any doubt that a wheel is damaged, immediately reduce your
speed and stop! Check the tyres for signs of damage (bulges, splits, etc.). If no ex-
ternal damage is evident, drive slowly and carefully to the nearest ŠKODA special-
ist garage to have the vehicle checked. Ð
188 General Maintenance

Handling wheels and tyres
Fig. 165
Changing wheels around
First read and observe the introductory information and safety warn-
ings on page 187.
Changing wheels around
If significantly greater wear is present on the front tyres, we recommend chang-
ing the front wheels around with the rear wheels as shown in the dia-
gram » Fig. 165. You will then obtain approximately the same life for all the tyres.
We recommend that you change the wheels around every 10
000 km in order to
achieve even wear on all wheels and to obtain optimal tyre life.
Storing tyres
Mark wheels before removing them so that their previous direction of running can
be maintained when mounted them again.
Always store wheels or tyres which been removed in a cool, dry and, where possi-
ble, dark place. Tyres which are not fixed to a wheel trim should be stored up-
right. ÐNew wheels and tyres
First read and observe the introductory information and safety warn-
ings on page 187.
Only fit tyres of the same type, size (rolling circumference) and the same tread
pattern on one axle on all 4
wheels.
The tyre/wheel combinations which are approved for your vehicle are indicated in
your vehicle documents.
ä
ä Proper knowledge of the tyre data makes it easier for you to select the correct
type of tyre. Tyres, for example, have the following inscription on their walls.
205/55

R 16 94 V
What this means is:
205 Tyre width in mm
55 Height/width ratio in %
R Code letter for the type of tyre - Radial
16 Diameter of wheel in inches
94 Load index
V Speed symbol The following speed restrictions apply to tyres.
Speed symbol Permissible maximum speed
S 180 km/h
T 190 km/h
U 200 km/h
H 210 km/h
V 240 km/h
W 270 km/h
Y 300 km/h The date of manufacture
is also stated on the tyre wall (possibly only on the in-
side of wheel ): e.g.
DOT ... 20

12...
means, for example, that the tyre was manufactured in the 20th week of 2012.
The following must be observed if only one temporary spare wheel is availa-
ble » page 190. Ð
189
Wheels and Tyres

Unidirectional tyres
First read and observe the introductory information and safety warn-
ings on page 187.
The direction of rotation of the tyres is marked by arrows on the wall of the tyre
.
The so specified running direction must absolutely be complied with. Only then
are the tyres able to provide the optimal properties in terms of grip, low noise,
wear-and-tear and aquaplaning.
If, in the event of a puncture, it is necessary to fit a spare wheel with a tyre with-
out a dedicated running direction or the opposite running direction, drive carefully
as the optimum characteristics of the tyre are no longer applicable in this situa-
tion. ÐSpare wheel
Fig. 166
Boot: Spare wheel
First read and observe the introductory information and safety warn-
ings on page 187.
The spare wheel is located in a well under the floor covering in the boot and is
fixed in place with a special bolt » Fig. 166.
Before removing the spare wheel, the box containing the vehicle tool kit must be
removed.
It is important to check the inflation pressure in the spare wheel (preferably every
time the tyre air pressure is checked - see sticker on the fuel filler flap »
page 188)
to ensure it is always ready to use.
ä
ä If the dimensions or design of the spare wheel differ from the tyres fitted to the
vehicle (e.g. winter tyres or low-profile tyres), it must only be used briefly in the
event of a puncture and if an appropriately cautious style of driving is adop-
ted » .
Replace it with a wheel having the appropriate mode and dimensions as soon as
possible
Temporary spare wheel
A warning label is displayed on the wheel rim of the spare wheel to indicate that
your vehicle is equipped with a temporary spare wheel.
Please observe the following when driving with a temporary spare wheel.
› The warning label must not be covered after installing the wheel.
› Do not drive faster than 80

km/h with the temporary spare wheel and pay par-
ticular attention while driving. Avoid accelerating at full throttle, sharp braking
and fast cornering.
› The inflation pressure for this spare wheel is identical to the maximum inflation
pressure of the standard tyres.
› Only use this temporary spare wheel to reach the nearest ŠKODA specialist ga-
rage as it is not intended for continuous use.
› No other summer or winter tyres must be mounted on the rim of the temporary
spare wheel R 18. WARNING
■ Never use the temporary spare wheel if it is damaged.
■ If the dimensions or design of the temporary spare wheel differ from the fit-
ted tyres, never drive faster than 80
km/h (or 50 mph). Avoid accelerating at
full throttle, sharp braking and fast cornering. CAUTION
Observe the instructions on the sticker on the temporary spare wheel. Note
The tyre pressure should be at the highest pressure specified for your vehicle at
all times. Ð
