Fig. 121
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 143.ä
ä 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 146.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 121, 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 Operation in winter
First read and observe the introductory information and safety warn-
ings on page 143.
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.

Inspecting and replenishing

Charging a vehicle battery
First read and observe the introductory information and safety warn-
ings on page 143.
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 164, 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 143.
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
Electrical power window (operational faults) » page 35
Enter the radio/navigation system code num-
ber » User manual of the radio
or » user manual of the naviga-
tion system
Setting the clock » page 11
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 143.
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

146 General Maintenance

Automatic load deactivation
First read and observe the introductory information and safety warn-
ings on page 143.
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

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. 122
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 148.
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. 122 - . 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. 122 - . The inflation pressures for winter tyres are 20 kPa
(0.2

bar) higher than those for summer tyres.
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.
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.
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.

1.6/77 kW TDI CR 220/210 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.£

Introduction
This chapter contains information on the following subjects:
Preliminary work 157
Changing a wheel 158
Subsequent steps 158
Loosening and tightening wheel bolts 159
Raising the vehicle 159
Securing wheels against theft 160
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. WARNING (Continued)
■ 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.
■ If the vehicle is subsequently fitted with tyres which are different to those it
was fitted with at the works, follow these guidelines »
page 150, 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

ä Subsequent steps
First read and observe the introductory information and safety warn-
ings on page 157.
The following steps must also be performed after changing the wheel.
›
Stow and attach the replaced wheel in the spare wheel well using a special
screw » page 151, 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
