■
Never work near open flames.
■
Always have a functioning fire extinguisher nearby.
WARNING■ Read the information and warning instructions on the fluid containers.■Keep fluids in their original containers and keep out of reach of children!■
If you wish to work under the vehicle, you must secure the vehicle from roll-
ing away and support it with suitable supporting blocks: the car jack is not
sufficient for this – risk of injury!
■
Never cover the engine with additional insulation material (e.g. with a blan-
ket) – risk of fire!
■
The bonnet must always be properly closed when driving. This is why after
closing the bonnet, the lock must always be checked to ensure it has engaged
properly.
■
If you notice that the lock is not properly engaged while driving, stop the ve-
hicle immediately and close the bonnet – risk of accident!
CAUTION
Always top up using the correct specification of fluids. This may result in major
operating problems and also vehicle damage!For the sake of the environmentIn view of the requirements for the environmentally friendly disposal of fluids and
the special tools and knowledge required for such work, we recommend that flu-
ids be changed by a specialist garage.
Note
■ Please consult a specialist garage for any questions relating to fluids.■Fluids with the correct specifications can be purchased from ŠKODA Original Ac-
cessories.

217Inspecting and replenishing

Checking the battery electrolyte levelFig. 188
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 224.
On vehicles with a vehicle battery fitted with a colour indicator, the so-called
magic eye » Fig. 188, 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.
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 ga-
rage, 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 tempera-
tures. A discharged vehicle battery may already freeze at temperatures just be-
low 0 °C .
We therefore recommend that you have the battery checked and, if necessary, re-
charged by a specialist garage before the start of the winter.
CAUTIONFor technical reasons, on vehicles with the description “AGM”, the electrolyte lev- el cannot be checked.
Note
The battery acid level is also checked regularly by a specialist garage as part of
the inspection service.
Charging
First read and observe the introductory information and safety warn-ings
on page 224.
A properly charged vehicle battery is essential for reliably starting the engine.
›
Switch off the ignition and all of the electrical components.
›
Only when performing a “quick-charge”, 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”).
›
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 themains 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”).
It is not necessary to disconnect the cables of the battery if you recharge the ve- hicle battery using low amperages (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 necessary to disconnect both cables before charging the battery with high
amperages, so-called “ quick-charging”.
The vent plugs of the vehicle battery should not be opened for charging. 
226General Maintenance

›The wheels of one axle are loaded more heavily (e.g. when towing a trailer or
when driving uphill or downhill).
› Snow chains are mounted.
› The spare wheel is mounted.
› One wheel per axle was changed.
For vehicles with Infotainment 1)
it can be determined which tyres should be
checked » Manual Infotainment , chapter Vehicle settings (key CAR) .WARNING■
When the warning light  illuminates, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Stop the vehicle as soon as
possible and inspect the tyres and their inflation pressure.■
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the  may light up after a delay, or not at all.
CAUTION
■
The tyre control display does therefore not replace the regular tyre inflation
pressure control, as the system cannot detect an even loss of pressure.■
The system cannot warn in case of very rapid tyre inflation pressure loss, e.g. in
case of sudden tyre damage. In this case carefully bring the vehicle to a standstill
without sudden steering movements or sharp braking.
■
To ensure a proper functioning of the tyre control display, it is necessary to re-
peat the basic setting every 10000 km or once a year.

240WARNING■ 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.■
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 vehicle is subsequently fitted with tyres which are different from
those it was fitted with at the works, follow these guidelines » page 230, New
tyres .
WARNINGObserve the following instructions for lifting 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 unexpectedly
rolling away.■
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.
■
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.
■
Never start the engine with the vehicle sitting on the raised jack – risk of in-
jury.
CAUTION
■ The tightening torque specified for the wheel bolts for steel and light alloy
wheels is 120 Nm.■
If the wheel bolts are fastened too tightly, this can cause damage to the anti-
theft wheel bolt or the adapter.
Note
The national legal requirements must be observed when changing a wheel.
Preparation
First read and observe the introductory information and safety warn-
ings
