WARNING (Continued)■If coolant is swallowed, consult a doctor immediately.■Never spill operating fluids over the hot engine - risk of fire.
CAUTION
■If for some reason it is not possible to top up the coolant under the current
circumstances,  do not continue driving! Switch off the engine and seek as-
sistance from a specialist garage.■
If the expansion tank is empty, do not top up with coolant. The system could
aerate - risk of engine damage, 
do not continue driving! Switch off the en-
gine and seek assistance from a specialist garage.
■
The amount of coolant additive in the coolant must never be allowed to be
less than 40 %.
■
Over 60 % of coolant additive in the coolant reduces the antifreeze protec-
tion and coolant effectiveness.
■
A coolant additive that does not comply with the correct specification can
significantly reduce the corrosion protection of the cooling system.
■
Any faults resulting from corrosion may cause a loss of coolant and can con-
sequently result in major engine damage!
■
Do not fill the coolant above the mark
A
» Fig. 188 on page 198 .
■
If an error occurs, leading to the engine overheating, the help of a professio-
nal garage is to be sought - there is a risk of serious engine damage occurring.
■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.
■
Never cover the radiator - there is a risk of the engine overheating.
Note
On vehicles that are fitted with an auxiliary heater (auxiliary heating and venti-
lation), the coolant capacity is approx. 1 l larger.

in the instrument cluster as well as the relevant notification » page 41. We still
recommend inspecting the coolant level directly at the expansion tank from
time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the cooling sys-
tem. Do not merely top up the coolant. Have the cooling system checked by a
specialist garage.
Replenishing
Read and observe
and on page 197 first.
The coolant expansion tank must always contain a small amount of cool-
ant » page 198, in section Introduction .

WARNING■
The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 192.■
Do not use used brake fluid - the function of the brake system may be im-
paired – risk of accident!
CAUTION
■ Do not continue your journey if the fluid level has dropped below the “MIN”
marking » Fig. 189 on page 199 ,  do not continue driving - there is a risk of
an accident! Seek help from a specialist garage.■
Brake fluid damages the paintwork of the vehicle.
Note
■ The brake fluid is changed as part of a prescribed inspection services.■We recommend using brake fluids from the ŠKODA Original Accessories
range.Checking the brake fluid levelFig. 189
Brake fluid reservoir
Read and observe and on page 199 first.
The fluid can be checked if the following conditions are met.
The vehicle is standing on a horizontal surface.
The engine is turned off.
The bonnet is open.
Checking the level
›
Check the level of brake fluid in the reservoir » Fig. 189.
The level must be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-
tear and automatic adjustment of the brake pads.
There may be an indication of a leak in the brake system, however, if the fluid
level drops significantly within a short time or if it drops below the “MIN” mark-
ing.
Too low brake fluid level is indicated by the warning light  being shown on
the display of the instrument cluster as well as the corresponding mes-
sage » page 35 .
Specification
Read and observe
and on page 199 first.
The brake fluid must comply with the following standards or specifications:› VW 50114;
› FMVSS 116 DOT4.
199Inspecting and replenishing

■Do not place the battery in direct daylight in order to protect the vehicle bat-
tery housing from the effects of ultra-violet light.■
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
■ We recommend having all work on the vehicle battery carried out by a spe-
cialist garage.■
You should replace batteries older than 5 years.
Opening the cover
Fig. 190
Polyester cover of vehicle bat-
tery
Read and observe and on page 200 first.
The battery is located in the engine compartment. For some equipment var-
iants, it is located underneath a polyester cover » Fig. 190.
›
Fold out the cover on the battery in the direction of the arrow.
The battery cover is installed in reverse order.
Checking the battery electrolyte levelFig. 191
Vehicle battery: Electrolyte level
indicator
Read and observe and on page 200 first.
On vehicles with a vehicle battery fitted with a colour indicator » Fig. 191, the
electrolyte level can be determined by looking at the change in colour of this
display.
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.
Vehicles with a START-STOP system are fitted with a battery control unit for
checking the energy level for the recurring engine start.
We recommend that you have the acid level checked regularly by a specialist
garage, especially in the following cases.
› High external temperatures.
› Longer day trips.
› After each charge.
Winter time
The vehicle battery only has a proportion of the starting power in lower tem-
peratures. 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,
recharged by a specialist garage before the start of the winter. 
201Inspecting and replenishing

Note■The battery acid level is also checked regularly by a specialist garage as part
of the inspection service.■
For technical reasons, on vehicles with the description “AGM”, the electrolyte
level cannot be checked.
Charging
Read and observe
and on page 200 first.
A properly charged vehicle battery is essential for reliably starting the engine.
A charging operation can be performed if the following conditions are satis-
fied.
The engine is turned off.
The ignition is switched off.
All consumers are turned off.
The bonnet is open.
“Fast charging” with high currents
›
Disconnect both battery cables (first of all “negative”, then “positive”).
›
Attach the terminal clamps of the charger to the battery terminals (red =
“positive”, black = “negative”).
›
Plug the mains cable of the charger into the power socket and switch on the
device.
›
After charging has been successful: Switch off the charger and remove the
mains cable from the power socket.
›
Only then disconnect the charger's terminal clamps.
›
Reconnect the cables to the battery (first of all “positive”, then “negative”).
Charging with low voltages
It is not necessary to disconnect the cables from the battery if you recharge
the vehicle battery, 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 low-
er) must be used until full charging is achieved.
The vent plugs of the vehicle battery should not be opened for charging.
WARNING■ 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.■
Creating a bridge between the poles on the battery (e.g. with metal ob-
jects - cables) creates a short circuit - risk of damage to the battery, explo-
sion and burning of the battery, jets of acid spurting out.
■
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 en-
gine, the ignition and all electrical components and disconnect the negative
terminal 
.
■
“Quick-charging” the vehicle battery is dangerous and requires a special
charger and specialist knowledge.
■
We therefore recommend that vehicle batteries be “rapidly charged” by a
specialist garage.
CAUTION
On vehicles with the START/STOP system or additional heating (auxiliary heat-
ing), do not connect the pole terminal of the charger directly to the negative
terminal of the vehicle battery, but rather only to the engine earth » page 220,
Jump-starting using the battery from another vehicle .
Replacing
Read and observe
and on page 200 first.
The new vehicle battery must have the same capacity, voltage, current and
size as the original battery. Suitable vehicle battery types can be purchased
from a specialist garage.
We recommend having the battery replaced by a specialist garage, where the
new vehicle battery will be installed properly and the original battery will be
disposed of in accordance with national regulations.
Disconnecting and reconnecting

CAUTION
■ Disconnect the vehicle battery only with the ignition turned off - there is a
risk of damaging the electrical system of the vehicle.■
Under no circumstances must the battery cables be connected incorrectly –
risk of a cable fire.
Note
■ After disconnecting and re-connecting the vehicle battery, we recommend
having the vehicle checked by a specialist to ensure that the full functionality
of all electrical systems is guaranteed.■
The data of the multi-function display will be reset.
Automatic load deactivation
Read and observe
and on page 200 first.
The vehicle voltage control unit automatically prevents the battery from dis-
charging when the bettery is subjected to heavy loads. 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 convenience consumers, e.g. seat heaters, rear win-
dow heaters, have their power limited or in case of emergency shut off com-
pletely.
CAUTION
■ 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 longer parking.■
Consumers which are supplied via a 12 V socket can cause the vehicle battery
to discharge when the ignition is switched off.
Note
Driving comfort is not disrupted by any shutting off of consumers. Often the
driver is not aware of it having taken place.203Inspecting and replenishing

Winter tyres
Summer tyres on ice, snee and at temperatures below 7 °C have less grip. This
is especially true of low-profile tyres or high-speed tyres .
The handling of your vehicle will be significantly improved when driving on
wintry roads if you fit winter tyres.
To ensure the best possible handling, winter tyres must be fitted to all four
wheels. The minimum tread depth is 4 mm.
Winter tyres (marked with M+S and a peak/snowflake symbol) of a lower speed
category can be used provided that the maximum permissible speed of these
tyres is not exceeded even if the maximum possible speed of the vehicle is
higher. 

tions must be observed before carrying out a wheel change on the road.
Switch on the hazard warning light.
The warning triangle must be set up at the prescribed distance - observe
the national legal provisions when doing so.
Park the vehicle as far away as possible from the flow of traffic.
Choose a location with a flat, solid surface.
Have all the occupants get out of the vehicle. While changing a tyre, the
occupants of the vehicle should not stand on the road (they should in-
stead remain behind a crash barrier).
If the vehicle is subsequently fitted with tyres which are different from those it
was fitted with at the works, follow these guidelines » page 207, Explanation
of the tyre labelling .
The national legal requirements must be observed when changing a wheel.
Preparation
Before changing the wheel, the following work must be carried out.
›
Switch off the engine.
›
Engage first gear or place the selector lever of the automatic transmission
into the P position .
›
Firmly apply the handbrake.
›
Uncouple any trailers.
›
Remove the vehicle tool kit » page 212 and the spare wheel » page 213 from
the boot.
Full wheel trim
Before removing the wheel bolts, remove the full wheel trim.
Extracting
›
Hook the clamp found in the vehicle tool kit » page 212 into the reinforced
edge of the wheel trim.
›
Push the wheel wrench through the clamp, support on the tyre and pull off
the wheel trim.
Installing
›
Press the wheel trim onto the wheel rim at the designated valve open-
ing » .
›
Then press the trim into the wheel rim until its entire circumference locks
correctly in place.
CAUTION
Notes on wheel trims supplied at the factory or from ŠKODAOriginal Accesso-
ries.■
When using an anti-theft wheel bolt, make sure that this has been fitted ac-
cording to the position marked on the back of the wheel cover position.
■
On the back of the wheel cover, the position for the anti-theft wheel bolt is
marked by means of a symbol. If the wheel cover is set outside the position
marked for the anti-theft wheel bolt, there is a risk of damaging the wheel
cover. 

into the mount on the jack
6
» page 212 .
›
Support the base plate of the jack with its entire surface resting on level
ground and ensure that the lever is positioned vertically to the jacking
point » Fig. 202 .
›
Use the crank to raise the jack until its claw encloses the bar » Fig. 202.
›
Continue to raise the jack until the wheel is just lifted off the ground.
WARNING■
Choose a flat and firm surface for jacking the vehicle.■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 unexpect-
edly rolling away.■
Secure the base plate of the lifting jack with suitable means to prevent
possible 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 nec-
essary 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.
■
Only attach the lifting jack to the attachment points provided for this pur-
pose.
■
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.
■
When the vehicle is raised, never start the engine.
CAUTION
It is important to ensure that the jack is correctly attached to the bar of the
lower beam, as otherwise there is a risk of damage to the vehicle.Anti-theft wheel boltsFig. 203
