– Reinstall the full wheel trim/wheel cap after removing the adapter or place the cap onto the safety wheel bolt.
– Have the tightening torque checked w i t h a t o rq u e w re n c h a s s o o n a s
possible. Steel and light alloy wheels must be tightened to a tightening
torque of 120 Nm.
The safety wheel bolts on vehicles fitted with them (one safety wheel bolt per
wheel) can only be loosened or tigh ten up by using the adapter provided.
It is meaningful to note the code numbe r hammered into the rear side of the
adapter or the rear side of the safety wheel bolts. You can obtain a replacement
adapter from a Škoda Service Partner, if necessary, by quoting this number.
We recommend that you always carry the adapter for the wheel bolts with you in
the vehicle. It should be st owed in the vehicle tool kit.
Caution
Damage can occur to the adapter and safety wheel bolt if the safety wheel bolt is
tightened up too much.
Note
The set of safety wheel bolts can be obtained from a Škoda Service Partner.
Jump-starting
Initial steps
You can use the battery of another vehicl e for jump-starting yours if the engine
does not start because the battery on your vehicle is flat. You will require jump-start
cables for this purpose.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the battery
supplying the power must not be significa ntly less than the capacity of the
discharged battery in your vehicle. Jump-start cables
Only use jump-start cables which have an
adequately large cross-section and insu-
lated terminal clamps. Please pay attent ion to the manufacturer's instructions.
Positive cable - colour coding in the majority of cases red.
Negative cable - colour coding in the majority of cases black.
WARNING
•A discharged battery may already freeze at temperatures just below 0°C.
In case of frozen battery carry out no jump-starting - risk of explosion!
•Please pay attention to the warning instructions relating to working in
the engine compartment ⇒page 210.
Note
•There must not be any contact between the two vehicles otherwise current may
flow as soon as the negative terminals are connected.
•The discharged battery must be properly connected to the system of the
vehicle.
•Switch off any mobile phone, pay attent ion to the instructions for use of the
mobile phone in such a situation.
•We recommend purchasing jump-start cabl es from Škoda Service Partners as a
Škoda original accessory or from retailers who sell branded batteries.

Start engine
It is important to connect the jump -start cables in the correct order.
Connecting positive terminals
– Attach one end to the positive terminal ⇒fig. 217 of the
discharged battery .
– Attach the other end to the positive terminal of the battery supplying the power .
Connecting negative term inal and engine block
– Attach one end to the negative terminal of the battery supplying
the power .
– Attach the other end to a solid metal part which is connected firmly to the engine block, or to the engine block itself.
Starting engine
– Start the engine of the vehicle providing current and run the engine at idling speed.
– Now start the engine of the vehicle with the discharged battery. – Interrupt the attempt at starting an engine after 10 seconds if it does
not start right away and wait for about 30 seconds before repeating
the attempt.
– Disconnect the cables on the engine in exactly the reverse order they
were connected up.
WARNING
•The non-insulated parts of the terminal clamps must never make contact
with each other. Furthermore, the cable connected to the positive terminal
of the battery must not come into contact with electrically conducting parts
of the vehicle - risk of a short circuit!
•Do not affix the jump starting cables to the negative terminal of the
discharged battery. There is the risk of detonating gas seeping out the
battery being ignited by the strong spark which results from the engine
being started.
•Run the jump-start cables so that th ey cannot be caught by any rotating
parts in the engine compartment.
•Do not bend over the batteries - risk of caustic burns!
•The vent screws of the battery cells must be tightened firmly.
•Keep any sources of ignition (naked flame, smouldering cigarettes etc.)
away from the battery - risk of an explosion!
Tow-starting and towing vehicle
General
Please pay attention to the following in structions if you are going to use a
tow rope:

– Release the clutch particularly gent ly when starting off or depress the
accelerator particularly gently if yo ur vehicle is fitted with an auto-
matic gearbox.
Driver of the towed vehicle
– Switch the ignition on so that the steering wheel is not blocked and you can also operate the turn signal lights, the headlight flasher, the
windscreen wipers and wi ndscreen washer system.
– Take the vehicle out of gear or move the selector lever into position N
if your vehicle is fitted with an automatic gearbox.
– Note that the brake servo unit and power steering only operate if the engine is running. You will require si gnificantly 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 241,
“Front towing eye” and ⇒page 241, “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 ro pe 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.

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 238 or call on the servic es of the SERVICE mobile.
If your vehicle has to be towed:
– Engage 2nd or 3rd gear wi th the vehicle stationary.
– Depress the clutch pedal fully and keep it depressed.
– Switch on the ignition.
– Wait until both vehicles are movi ng 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 possibl e to tow-start a car fitted with an automatic
gearbox .
WARNING
There is high risk of having an accide nt when tow-starting a vehicle, when
for example the towed vehicle r uns 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 239. 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 239.
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 runni ng; the gearbox would not be adequately
lubricated at higher speeds an d over longer towing distance.
Caution
If the vehicle is towed in by a recovery vehi cle, it should only be towed in with the
front wheels raised. If the vehicle is ra ised 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. 222 or the fuse cover in the engine compartment
⇒ page 244.
– Find out which fuse belongs to the relevant component ⇒page 247,
“Fuse assignment in the dash panel”, ⇒page 244, “Fuse assignment
in engine compartment - version 1” or ⇒page 246, “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. You can obtain replacement fuses 12) from a Škoda
Service Partner.
Colour coding of fuses
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.
