from rolling away and support it with suitable supporting blocks; the car jack
is not sufficient – risk of injury!
■
Never cover the engine with additional insulation material (e.g. with a cover)
– risk of fire!
■
The bonnet must always be properly closed when driving. Therefore, the
lock must always be checked after closing the bonnet in order to ensure that
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 environment
In 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 proper specifications can be purchased from the ŠKODA Original
Accessories or from the ŠKODA Genuine Parts ranges.

Checking the battery electrolyte level
Fig. 164
Vehicle battery: Electrolyte level
indicator
First read and observe the introductory information and safety warn-
ings on page 207.
On vehicles with a vehicle battery fitted with a colour indicator » Fig. 164 , 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 carefullyknock 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 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.
CAUTION
For 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 207.
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
“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 thedevice.
›
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 “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. 
209Inspecting and replenishing

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 warning light  can be delayed or does not light up 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.

224WARNING■ 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 214, New
tyres .
89WARNINGNotes for vehicle lifting■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.
WARNINGInformation on the wheel bolts■The wheel bolts must be clean and must turn easily. Never treat them with
grease or oil.■
The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
■
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!
Note
The national legal requirements must be observed when changing a wheel.

rect » page 212 .

Follow-up tasks
First read and observe the introductory information and safety warn-
ings
on page 221.
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 bolt » page 216 .
›
Stow the tool kit in the space provided and secure using the band.
›
Check the tyre pressure on the installed spare wheel as soon as possible.
