Breakdown assistance

– Note that the brake servo unit and power steering only operate if the engine is running. You will require significantly greater
physical force to depress the brake pedal and to steer the
vehicle if the engine is not running.
– Ensure that the tow rope is always kept taught.
Tow rope or tow bar
A tow bar is safest way of towing a vehicle and also minimizes any
shocks. You can use a tow rope only if a suitable tow bar is not available.
The tow rope must be elastic to protect the vehicle. Thus one should only
use plastic fibre rope or a rope made out of a similarly elastic material.
Only attach the tow rope to the towing eyes provided for this purpose
⇒ page 285, “Front towing eye” and ⇒page 286, “Rear towing eye”.
Driving style
Towing another vehicle requires a certain amount of practice. Both drivers
should be familiar with the particular points about towing a vehicle.
Unskilled drivers should not attempt to tow in another vehicle or to be
towed in.
One should be constantly vigilant not to allow impermissibly high towing
forces or jerky loadings. There is always a risk of excessive stresses and
damage resulting at the points to which you attach the tow rope or tow bar
when you attempt to tow a vehicle which is not standing on a paved road.
Caution
If the gearbox of your vehicle no longer contains any oil because of a
defect, your vehicle must only be towed in with the driven wheels raised
clear of the ground, or on a special vehicle transporter or trailer.
Note
•Please comply with any legal requirements particularly regarding the
switched on signal systems, when towing in or tow-starting another
vehicle.
•The tow rope must not be twisted as it may in certain circumstances
result in the front towing eye being unscrewed out of your vehicle.

Rear towing eye
– Take the cover out of the bumper ⇒fig. 215 . – Screw in the towing eye anticlockwise down to the stop
⇒fig. 216 and tighten up using the wheel wrench (push the
wheel wrench through eye).
– Put the cover in place after screwing out the towing eye again and press into place. The cover must engage firmly.
Tow-starting a vehicle
If the engine does not start, we generally do not recommend to
tow-start your vehicle. One should attempt to start the engine
using jump start cables ⇒page 281 or call on the services of the
SERVICE mobile.
If your vehicle has to be towed:
– Engage 2nd or 3rd gear with the vehicle stationary.
– Depress the clutch pedal fully and keep it depressed.
– Switch on the ignition.
– Wait until both vehicles are moving then release the clutch pedal slowly.
– Depress the clutch pedal fully when the engine fires and take the vehicle out of gear.
For technical reasons it is not possible to tow-start a car fitted with an
automatic gearbox .

WARNING
There is high risk of having an accident when tow-starting a
vehicle, when for example the towed vehicle runs into the towing
vehicle.
Caution
Vehicles which are fitted with a catalytic converter should not be tow-
started over a distance of more than 50 metres. Unburnt fuel may get into
the catalytic converter and damage it.
Towing in a vehicle fitted with a manual gearbox
Please refer to the notes ⇒page 283.
The car can be towed in with a tow bar or a tow rope or with the front or
rear wheels raised. The maximum towing speed is 50 km/h.
Towing of a vehicle with an automatic gearbox
Please refer to the notes ⇒page 283.
The car can be towed in with a tow bar or a tow rope. Refer at the same
time to the following guidelines:
•Move selector lever into N .
•The maximum towing speed is 50 km/h.
•The maximum permissible towing distance is 50 km. The gear oil
pump does not operate when the engine is not running and the gear would
not be adequately lubricated at higher speeds and over longer towing
distance.
Caution
If the vehicle is towed in by a recovery vehicle, it should only be towed in
with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged! (Does not apply to the automatic gearbox DSG).
Note
The vehicle must be transported on a special vehicle or trailer if it is not
possible to tow in the vehicle in the way described or if the towing distance
is greater than 50 km.

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!
