Electric fuses
Replacing fuses
Defect fuses must be replaced.
Individual electrical circuits are protected by fuses. The fuses are
located on the left side of the dash panel behind the safety cover
and under the cover in the engine compartment on the left.
– Switch the ignition off and also the electrical component
affected.
– Use a screwdriver to take off the fuse cover on the side of the dash panel ⇒fig. 217 or the fuse cover in the engine compart-
ment ⇒page 289. – Find out which fuse belongs to the relevant component
⇒page 293, “Fuse assignment in the dash panel” or
⇒ page 290, “Fuse assignment in engine compartment -
version 1” or ⇒page 291, “Fuse assignment in engine
compartment - version 2”.
– Take the plastic clip out of its fixture in the fuse cover, insert it onto the respective fuse and pull out this fuse.
– Defect fuses can be detected by their melted metal strips. Replace the defect fuse by a new fuse of the same ampere
number.
– Fit on the fuse cover again.
We recommend that you carry the box of replacement fuses with you
which was delivered in your vehicle. Replacement fuses 12) are available
at Škoda dealers.

Caution
•Never attempt to “repair” fuses and also do not replace them with a
fuse of a higher amperage - risk of fire! This may also cause damage at
another part of the electrical system.
•Have the electrical system checked as quickly as possible by a
specialist garage if a newly inserted fuse blows again after a short time.
Fuse cover in engine compartment
The fuse box in the engine compartment exists in two
different versions. You can determine which version your
vehicle is fitted with after removing the fuse cover at the
location of the fuses.
For particular model versions, the battery must be removed
before removing the fuse cover ⇒page 258.
Removing fuse cover
– Move the circlips ⇒fig. 218 as far as the stop, the symbol
 appears behind the circlip and remove the cover.
Installing fuse cover
– Position the fuse cover on the fuse box and push the circlips as far as the stop - the symbol
 is visible behind the
circlip.

Caution
•When unlocking and locking the fuse cover, it must be pressed on the
sides to the box, otherwise damage can occur to the locking mechanism.
•Carefully position the fuse cover in the engine compartment. If the
cover was not correctly positioned, water can get into the fuses and this
results in a damage to the vehicle!

Electrically adjustable seats are protected by automatic circuit
breakers , which switch on again automatically after a few seconds after
the overload has been eliminated.
Bulbs
Changing bulbs
The relevant lamp must always be switched off before a light bulb is
replaced.
Defect light bulbs should only be replaced with light bulbs of the same
type. The designation is located on the light socket or the glass bulb.
Changing certain bulbs is not something which you can do yourself, but
requires to be done by a specialist. Other parts of the vehical must be
removed in order to change the light bulbs. This applies, in particular, to
bulbs which can only be reached from the engine compartment.
We therefore recommend that you have any bulbs changed by a Škoda
dealer or, in exceptional cases, by calling on other professional assist-
ance.
Please note that the engine compartment is a hazardous area ⇒page 248.
We recommend that you carry the set of light bulbs with you which was
delivered in your vehicle. Replacement light bulbs
13) are available at
specialist garages.
The set of light bulbs is stowed in the locable box in the spare wheel.
Fitted with a xenon headlight
Change of light bulbs on Xenon lights (low beam lights, parking lights and
main beam lights) should be undertaken by a specialist garage.

WARNING
•Bulbs H7 and H1 are pressurised and may burst when changing
the bulb - risk of injury!
•It is recommended to wear gloves and eye protection when
changing a light bulb.
•Gas discharge bulbs* (xenon bulbs) operate with a high voltage,
professional knowledge is required - danger to life!
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,
serviette or something similar.
Note
This Owner's Manual only describes the replacement of bulbs where it is
assumed that no major complications will arise. Other light bulbs should
be changed by your specialist garage.
