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 201 first.
The vehicle's electrical system automatically prevents the battery from dis-
charging when the battery is being heavily used. 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.204General Maintenance

Raising the vehicle›Insert the crank 7 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. 222 .
›
Use the crank to raise the jack until its claw encloses the bar » Fig. 222.
›
Continue to raise the jack until the wheel is just lifted off the ground.
WARNING■
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.
Remove the wheel / fix
When changing a wheel, the following instructions must be followed.
›
Remove the full wheel trim or the caps of the wheel bolts.
›
First of all slacken the anti-theft wheel bolt and then the other wheel bolts.
›
Jack up the vehicle until the wheel that needs changing is clear of the
ground.
›
Unscrew the wheel bolts and place them on a clean surface (cloth, paper,
etc.).
›
Remove the wheel carefully.
›
Attach the wheel and slightly screw on the wheel bolts.
›
Lower the vehicle.
› Tighten the wheel bolts opposite each other using the wheel wrench (alter-
nating crosswise). Tighten the anti-theft wheel bolt last.›
Replace the wheel trim and the caps.
When fitting unidirectional tyres, ensure that the direction of rotation is cor-
rect » page 207 .
All bolts must be clean and must turn easily.
If it is established when changing a wheel that the wheel bolts are corroded and difficult to move, then these must be replaced.
Under no circumstances grease or oil the wheel bolts!
WARNINGUndo the wheel bolts only a little (about one turn) as long as the vehicle
has not yet been jacked up. Otherwise the wheel could become loose and
fall off.
Follow-up tasks
After changing the wheel, the following work must be carried out.
›
Stow the replaced wheel in the wheel well and secure it with a special screw.
›
Stow the tool kit in the space provided and secure using the band.
›
Check the tyre pressure on the installed wheel as soon as possible.
›
Have the tightening torque of the wheel bolts checked with a torque wrench
as soon as possible.
After changing the wheel, the tyre pressure must be adjusted. In vehicles with
tyre pressure monitoring, save tyre pressure values » page 165.
Replace the damaged wheel or consult a specialist garage about repair op-
tions.
The prescribed tightening torque of the wheel bolts is 120 Nm.
WARNING■
If the wheel bolts are tightened to a too low tightening torque, the rim
can come loose when the car is moving. A tightening torque which is too
high can damage the bolts and threads and this can result in permanent
deformation of the contact surfaces on the rim.■
Drive cautiously and only at a moderate speed until the tightening torque
has been checked.
216Do-it-yourself

General informationRead and observe
on page 217 first.
For your own safety and the safety of your passengers, the following instruc-
tions must be observed before carrying out a wheel repair on the road.
Switch on the hazard warning light.
Place the warning triangle at the prescribed distance.
Park the vehicle as far away as possible from flowing traffic.
Choose a location with a flat, solid surface.

CAUTION
■
“Never repair” fuses, and do not replace them with fuses of a higher amper-
age – risk of fire! This may also cause damage at other points in the electrical
system.■
If a newly inserted fuse blows again after a short time, have the electrical
system checked as quickly as possible by a specialist garage.
■
A blown fuses is recognisable by the molten metal strip. Replace the faulty
fuse with a new one of the same amperage.
Note
■
We recommend always carrying replacement fuses in the vehicle. A box of
replacement fuses and bulbs can be purchased from ŠKODA Original Accesso-
ries.■
There can be several power consuming devices for one fuse.
■
Multiple fuses may exist for a single power consuming device.

Some manual skills are required to change a bulb. For this reason, we recom-
mend having bulbs replaced by a specialist garage or seeking other expert help
in the event of any uncertainties.
▶ Switch off the ignition and the relevant lights before replacing a bulb.
▶ Faulty bulbs must only be replaced with the same type of bulbs. The designa-
tion is located on the light socket or the glass bulb.
A stowage compartment for replacement bulbs is located in a plastic box in
the spare wheel or underneath the floor covering in the luggage compartment.
We recommend having the headlight settings checked by a specialist garage
after replacing a bulb in the low, high or fog beam.
In case of failure of a xenon gas discharge lamp or an LED diode, visit a special- ist garage.
WARNING■ Always read and observe the warnings before completing any work in the
engine compartment » page 194.■
Accidents can be caused if the road in front of the vehicle is not suffi-
ciently illuminated and the vehicle cannot or can only be seen with difficul-
ty by other road users.
■
Bulbs H7 H8 and H15 are pressurised and may burst when changing the
bulb - risk of injury! We therefore recommended wearing gloves and safety
glasses when changing a bulb.
■
Do not carry out any work on the Xenon gas discharge lamps - risk of
death!
CAUTION
Do not take hold of the glass bulb with naked fingers (even the smallest
amount of dirt reduces the working life of the light bulb). Use a clean cloth,
napkin, or similar. 230Do-it-yourself
