When refilling, we only recommend you use the same antifreeze described on the
antifreeze expansion tank.
Please contact an authorised
ŠKODA Service Partner if you have any questions re-
garding the coolant or if you wish to fill up with a different coolant.
An authorised ŠKODA Service Partner can also supply you with the correct coolant
additives.

CAUTION
● Other coolant additives may cause operational problems which, in particular,
involves significantly reducing the anticorrosion effect.
● Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequence of this, result in major engine damage. Inspecting the coolant level Fig. 125 Engine compartment: Coolant
expansion bottle
The coolant expansion bottle is located in the engine compartment on the right.
– Switch the engine off.
– Open the bonnet ⇒  in Working in the engine compartment on page 151.
– Check the level of coolant in the coolant expansion bottle ⇒ fig. 125 . The cool-
ant level when the engine is cold must lie between the
“MIN” B and “MAX”
A markings. The level may also rise slightly above the “MAX” marking when the
engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light
in the instrument cluster 
⇒  page 23. We still recommend inspecting the coolant
level directly at the reservoir from time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. You
should not merely top up the coolant in the reservoir. It is also important to have
the cooling system inspected without delay by a specialist garage.
Losses can only occur through the pressure relief in the cap of the coolant expan-
sion bottle which is completely free of leaks if the coolant boils as a result of over-
heating and is forced out of the cooling system. WARNING

Battery cover
Fig. 127 The battery: Pull up the cover (automatic gearbox)/(manual gearbox)
The battery is located in the engine compartment below a plastic box.
– Unlock the interlock on the positive terminal side of the battery ⇒ fig. 127.
– Pull up the cover in direction of arrow ⇒  fig. 127 (automatic gearbox) or
⇒  fig. 127 (manual gearbox).
– The installation of the battery cover on the positive terminal side takes place
in the reverse order. 
Battery control Fig. 128 The battery: Electrolyte level
indicator
The battery is practically maintenance-free under normal operating conditions. We recommend you have the electrolyte level checked by a specialist garage from
time to time, especially in the following cases.
● High outside temperatures.
● Long daily drives
● After each charge ⇒
 page 159.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called mag-
ic eye ⇒ fig. 128 , 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 an authorised
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. 
Operation in winter The battery has to provide greater amounts of electricity during the winter. It also
has only part of the initial power output at low temperatures that it has at normal
temperatures.
A discharged battery may already freeze at temperatures just below 0 °C.
We therefore recommend that you have the battery checked by a specialist ga-
rage before the start of the winter, and recharged if necessary. WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic burns.
Replace a frozen battery. 158
Inspecting and Replenishing

Charging the battery
A properly charged battery is essential for reliably starting the en-
gine.
– Read the warning notes ⇒   in General information on page 157 and
⇒  .
– Switch the ignition and all electrical components off.
– Only for “quick-charging”: Disconnect both battery cables (first of all “nega-
tive
”, then “positive”).
– Carefully attach the terminal clamps of the charger to the battery terminals
(red = “positive

”, black = “negative”).
– You can now plug the mains cable of the charger into the power socket and
switch on the charger.
– When charging is completed: switch the charger off and unplug the mains ca-
ble from the power socket.
– Only then should you disconnect the terminal clamps of the charger.
– Reconnect the cables to the battery (first of all “positive”, then “negative”).
It is not normally necessary to disconnect the cables of the battery if you recharge
the battery using low amperages (as for example from a mini-charger). Please al-
so refer to the instructions from the charger manufacturer.
A charging current of 0.1 of the total battery capacity (or lower) is that which
should 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” a battery is dangerous ⇒  in General information on page 157.
It requires a special charger and specialist knowledge. We recommend having the
quick charging of vehicle batteries undertaken by a specialist garage.
A discharged battery may already freeze at temperatures just below 0

°C ⇒  . We
recommend that you no longer use a battery which has thawed out because the
casing of the battery may be cracked through the formation of ice and this would
allow battery electrolyte to flow out.
The vent plugs of the battery should not be opened for charging. WARNING
● Never charge a frozen or thawed battery - risk of explosion and caustic
burns. Replace a frozen battery.
● Never charge a battery which has a too low electrolyte level - risk of explo-
sion and caustic burns. 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 ⇒ fig. 143. 
Disconnecting and reconnecting the battery On disconnecting and reconnecting the battery the following functions are initially
deactivated or are no longer able to operate fault-free.

Replacing the battery When replacing a battery, the new new battery must have the same capacity,
voltage (12

V), amperage and be the same size. Suitable types of vehicle battery
are available from an authorised ŠKODA Service Partner.
We recommend you have a battery change carried out by an authorised ŠKODA
Service Partner, who will properly install the new battery and dispose of the origi-
nal one. £ 159

CAUTION
Vehicles with a “START-STOP” system are fitted with a special battery type which
allows the battery control unit to check the energy level for recurring engine start.
This battery must only be replaced by a battery of the same type. For the sake of the environment
Batteries contain poisonous substances such as sulphuric acid and lead. For this
reason, it must be disposed of properly. Under no circumstances must it be dis-
posed of in the communal rubbish. 
Automatic consumer shut-off Under heavy load on the vehicle battery, the vehicle electrical system manage-
ment automatically takes various measures to avoid draining the vehicle battery.
●
The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
● If necessary, some electrical consumers are limited in their performance or are
temporarily switched 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. 
Windshield washer system Fig. 129 Engine compartment: Wind-
shield washer fluid reservoir The windshield washer fluid reservoir contains the cleaning fluid for the wind-
shield or rear window and for the headlamp cleaning system. The reservoir is loca-
ted in the front of the engine compartment on the right side of the vehicle
⇒ fig. 129
. On some vehicles, the reservoir is located on the left side of the vehicle
next to the battery.
The filling level of the container is about 3.5 litres and about 5.4 litres on vehicles
which have a headlight washing system.
Clear water is not sufficient to intensively clean the windshield and headlights.
We therefore recommend using clean washing water together with the screen
cleaner from
ŠKODA Original Accessories (in winter additionally with antifreeze)
which is capable of removing stubborn dirt. Follow the instructions for use on the
packaging when using screen cleaning products.
You should always add antifreeze to the cleaning water in winter even if your ve-
hicle is fitted with heated windshield washer nozzles.
It is also possible in exceptional cases to use methylated spirits when no screen
cleaner with antifreeze is available. The concentration of methylated spirits must
not be more than 15 %. Please note, however, that the antifreeze protection at
this concentration is only adequate down to -5 °C. WARNING
Read and observe the warning notes ⇒ page 150
, Working in the engine com-
partment before working in the engine compartment. CAUTION
● On no account should you add radiator antifreeze or other additives to the
windshield washer fluid.
● If the vehicle is fitted with a headlight cleaning system, you should only add
cleaning products which do not attack the polycarbonate glass of the headlights
to the windshield washer fluid. Please contact an authorised

ŠKODA Service Part-
ner who will help you select a suitable cleaning agent. Note
Do not take the filter out of the windshield wash container when filling it up again
with liquid otherwise dirt can get into the liquid transportation system and can
lead to faults in operation of the windshield wash system. 160
Inspecting and Replenishing

Always check the inflation pressure of tyres when cold. Do not reduce the higher
pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if
your vehicle is carrying a significantly higher payload.
Tyre inflation pressure - Tyre size 185/55
R15
The same inflation pressure values apply to tyres of the tyre size 195/55 R15 as to
tyres of the tyre size 185/55 R15 which are intended to be used with snow chains,
see the inside of the fuel filler flap.
The tyres of the tyre size 185/55 R15, which are intended to be used with snow
chains and are fitted on models Roomster Scout, have the following inflation
pressure values in kPa. Engine Partial load Full load

Driving style
Fast cornering, sharp acceleration and braking (squealing tyres) increase wear-
and-tear on 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.
You should have the wheels rebalanced since any imbalance increases wear-and-
tear on the steering, the suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted and each time a tyre is repaired.
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. Contact
your specialist garage if you notice any unusual tyre wear. WARNING
● If the inflation pressure is too low, the tyre must perform a higher rolling
resistance. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and even a tyre blowout.
● Immediately replace the damaged rims or tyres.
● Tyres which are 6 years old or more should only be fitted in exceptional ca-
ses and when adopting an appropriately cautious style of driving. For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption. 
Wear indicators Fig. 131 Tyre tread with wear indicators
The base of the tread of the original tyres has wear indicators 1.6 mm high, instal-
led at right angles to the direction of travel. These wear indicators are located at 6
- 8 points depending on the make and are evenly spaced around the circumfer-
ence of the tyre ⇒ fig. 131. Markings on the walls of the tyres through the letters
“TWI”, triangular symbols or other symbols identify the position of the wear indi-
cators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the
wear indicators, means that your tyres have reached their legally permissible mini-
mum tread depth. £162

WARNING
● If you find yourself in flowing traffic switch on the hazard warning lights
system and place the warning triangle on the side of the road at the prescri-
bed distance from your vehicle. Comply with the national legal regulations. In
this way you are protecting not only yourself but also other road users.
● Never start the engine with the vehicle sitting on the raised jack - danger
of suffering injury. CAUTION
If you have to change a wheel on a slope first block the opposite wheel with a
stone or similar object in order to secure the vehicle from unexpectedly rolling
away. Note
Comply with the national legal regulations. 
Changing a wheel Always change a wheel on a level surface as far as possible.
–
Take off the full wheel trim ⇒ page 170 or the caps ⇒ page 170.
– Slacken the wheel bolts ⇒ page 170.
– Jack up the vehicle until the wheel to be changed is clear of the ground
⇒ page 171.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper, etc.).
– Take off the wheel.
– Fit on the spare wheel and tighten the wheel bolts slightly.
– Lower the car.
– Tighten the wheel bolts firmly, alternately and diagonally using the wrench
(crosswise) ⇒ page 170.
– Mount the full wheel trim/wheel trim cap or the caps. Note
● All bolts must be clean and must turn easily.
● You must never grease or oil the wheel bolts!
● When fitting on unidirectional tyres, ensure that the tyres rotate in the correct
direction ⇒ page 161
. 
Subsequent steps After changing the wheel, you must perform the following steps.
–
Stow the vehicle tool kit in the space provided.
– Stow the replaced wheel in the luggage compartment.
– Check the tyre pressure on the spare wheel just mounted as soon as possible.
– Have the tightening torque of the wheel bolts checked with a torque wrench
as soon as possible. Steel and light alloy wheels must be tightened to a tight-
ening torque of 120

Nm.
– Change the damaged wheel or consult a specialist garage about possibilities
for getting repairs done. WARNING
It is necessary to observe the guidelines given on ⇒
 page 163, New tyres and
wheels if the vehicle is subsequently fitted with tyres which are different to
those it was fitted with at the works. Note
● If you find, when changing the wheel, that the wheel bolts are corroded and
difficult to turn, the bolts must be replaced before checking the tightening torque.
● Drive cautiously and only at a moderate speed to a workshop where the tight-
ening torque can be checked.  169

Jump-starting Initial steps You can use the battery of another vehicle for jump-starting yours if the engine
does not start because the battery on your vehicle is flat. You will require jump-
start cables 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. Please pay attention to the manufacturer's instructions.
Positive cable - colour coding in the majority of cases red.
Negative cable -
colour coding in the majority of cases black. WARNING
● A discharged battery may already freeze at temperatures just below 0 °C.
In case of frozen battery carry out no jump-starting - risk of explosion! Also af-
ter thawing of the battery there is a risk of caustic burns due to leaking acid.
Replace the frozen battery.
● Please pay attention to the warning instructions relating to working in the
engine compartment ⇒ page 150

. 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.
● Switch off the car phone. Heed the advice concerning the use of mobile
phones in such a situation.
● We recommend you buy jump-start cables from a car battery specialist. 
