Before placing the lifting jack back into its storage area, screw in the arm of the
lifting jack fully. WARNING
■ The factory-supplied lifting jack is only intended for your model of vehicle.
Under no circumstances attempt to lift heavier vehicles or other loads - risk of
injury!
■ Ensure that the vehicle tool kit is safely secured in the boot. Note
Ensure that the box is always secured with the strap. ÐChanging a wheel

Introduction
This chapter contains information on the following subjects:
Preliminary work 157
Changing a wheel 158
Subsequent steps 158
Loosening and tightening wheel bolts 159
Raising the vehicle 159
Securing wheels against theft 160
WARNING
■ 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. In this way you are not only protecting yourself
but other road users as well.
■ If the wheel is damaged or in the event of a puncture, park the vehicle as far
away as possible from the flow of traffic. Park on as flat and firm a surface as
possible. WARNING (Continued)
■ 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.
■ If the vehicle is subsequently fitted with tyres which are different to those it
was fitted with at the works, follow these guidelines »
page 150, New wheels
and tyres.
■ 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. ■ 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.
■ Never start the engine with the vehicle sitting on the raised jack - danger of
suffering injury.
■ Only attach the lifting jack to the attachment points provided for this pur-
pose. CAUTION
■ The prescribed tightening torque of the wheel bolts for steel and light alloy
wheels is 120 Nm.
■ If the anti-theft wheel bolt is fastened too tightly, it can cause damage to the
anti-theft wheel bolt and adapter. Note
■ The anti-theft wheel bolt set and adapter can be purchased from a
ŠKODA Serv-
ice Partner. ■ The national legal requirements must be observed when changing a wheel. Ð Preliminary work
First read and observe the introductory information and safety warn-
ings on page 157.

Jump-starting
ä
Introduction
This chapter contains information on the following subjects:
Jump-starting 163
Jump-starting in vehicles with the START-STOP system 164
The battery of another vehicle can be used to jump-start your vehicle if the en-
gine will not start because the battery is flat. Jump-start cables are required 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 significantly less than the capacity of the dis-
charged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and in-
sulated terminal clamps. Observe the manufacturer's instructions.
Positive cable - colour coding in the majority of cases is red.
Negative cable - colour coding in the majority of cases is black. WARNING
■ A discharged vehicle battery may already freeze at temperatures just below
0 °C. In case of frozen battery carry out no jump-starting - risk of explosion! ■ Pay attention to the warning instructions relating to working in the engine
compartment »
page 136, Engine compartment .
■ The non-insulated parts of the terminal clamps must never make contact
with each other. In addition, the jump-start cable connected to the positive
terminal of the battery must not come into contact with electrically conduct-
ing parts of the vehicle - risk of short circuit!
■ Do not clamp the jump-start cable to the negative terminal of the dis-
charged 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.
■ Route the jump-start cables so that they cannot be caught by any rotating
parts in the engine compartment.
■ Do not bend over the battery - risk of caustic burns!
■ The vent screws of the battery cells must be tightened firmly. WARNING (Continued)
■ Keep any sources of ignition (naked flame, smouldering cigarettes, etc.)
away from the battery - risk of an explosion! ■ Never jump-start vehicle batteries with an electrolyte level that is too low -
risk of explosion and caustic burns. 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 vehi-
cle. ■ We recommend you buy jump-start cables from a car battery specialist. Ð Jump-starting

Attach the other end 4
to a solid metal part which is connected firmly to the
engine block, or to the engine block itself.
Starting engine
› Start the engine on the vehicle providing the power and allow it to idle.
› Now start the engine of the vehicle with the discharged battery.
› If the engine does not start, terminate the attempt to start the engine after
10 seconds and wait for about 30 seconds before repeating the process.
› Disconnect the cables in exactly the
reverse order to the one described above. ÐJump-starting in vehicles with the START-STOP system
Fig. 136
Jump-starting - START-STOP
system
First read and observe the introductory information and safety warn-
ings on page 163.
On vehicles with the START-STOP system, the jump-start cable of the charger
must never be connected directly to the negative pole of the vehicle battery, but
only to the engine earth » Fig. 136. ÐTowing the vehicle
ä
Introduction
This chapter contains information on the following subjects:
Front towing eye 165
Rear towing eye 165
Vehicles with manual transmission can be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
ä Vehicles with automatic transmission can be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the automatic
gearbox is damaged!
A tow bar
is the safest way of towing a vehicle and also minimises any shocks.
Only use a tow rope if a suitable tow bar is not available.
When towing, the following guidelines must be observed.
Driver of the tow vehicle
› Release the clutch particularly gently when starting off or depress the accelera-
tor particularly gently if the vehicle is fitted with an automatic gearbox.
› On vehicles with a manual transmission, only push down on the accelerator
pedal once the rope is taught.
The maximum towing speed is 50 km/h.
Driver of the towed vehicle
› Switch on the ignition so that the steering wheel is not blocked and so that the
turn signal lights, horn, windscreen wipers and windscreen washer system can
be switched on.
› Take the vehicle out of gear or move the selector lever into position
N if the
vehicle is fitted with an automatic gearbox.
Please note that the brake servo unit and power steering only operate if the en-
gine is running. If the engine is not running, significantly more physical force is re-
quired to depress the brake pedal and steer the vehicle.
If using a tow rope, ensure that it is always kept taught. CAUTION
■ Do not tow start the engine - danger of damaging the engine! On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. The bat-
tery from another vehicle can be used as a jump-start aid » page 163, Jump-start-
ing .
■ 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.
■ 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. ■ To protect both vehicles when tow-starting or towing, the tow rope should be
elastic. Thus one should only use plastic fibre rope or a rope made out of a simi-
larly elastic material. £

Some manual skills are required to change a bulb. For this reason, if uncertain, we
recommend that bulbs are replaced by a ŠKODA specialist garage or other expert
help is sought. ›
Switch off the ignition and all of the 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 boot. WARNING
■ Accidents can be caused if the road in front of the vehicle is not sufficiently
illuminated and the vehicle cannot or can only be seen with difficulty by other
road users.
■ Always read and observe the warnings before completing any work in the
engine compartment » page 136, Engine compartment .
■ Bulbs H7 and H4 are pressurised and may burst when changing the bulb -
risk of injury! We therefore recommended wearing gloves and safety glasses
when changing a bulb. 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, nap-
kin, or similar. ■ When removing and installing the tail light make sure that the paintwork of the
vehicle and the tail light are not damaged. Note
■ This Owner's Manual only describes the replacement of bulbs where it is possi-
ble to replace the bulbs on your own without any complications arising. Other
light bulbs should be changed by a

ŠKODA specialist garage.
■ We recommend that a box of replacement bulbs be always carried in the vehi-
cle. Replacement bulbs can be purchased from
ŠKODAOriginal Accessories.
■ We recommend that the headlight settings are checked by a ŠKODA specialist
garage after replacing a bulb in the main or low beam.
■ LED diodes should be changed by a specialist ŠKODA garage. Ð
