should be attached to folding arms. Adjust
the mirrors so that they provide you with
an adequate field of view to the rear.
Headlights
Before starting off with a hitched trailer, also check the setting of the headlights.
Alter the setting as necessary with th e aid of the headlight beam adjuster
⇒ page 55.
Detachable ball head
The ball rod is detachable on vehicles which feature a factory-fitted towing device.
It is stowed together with separate fitting instructions in the spare wheel well in the
luggage compartment of the vehicle.
Further information on the towing device ⇒page 198.
Note
•We recommend that you also have yo ur vehicle inspected between service
intervals if you tow a trailer frequently.
•The handbrake on the towing vehicle must be put on when coupling and
decoupling the trailer.
Driving Tips
Particular caution is required when towing a trailer.
– Do not, as far as possible, drive with your vehicle unladen and the
trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temperature gauge if the outside temper- ature is high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer
is laden. Maintain a particularly low speed if you cannot avoid driving with this
combination.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for coun-
tries in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with
increasing speed means that the legally allowed speed should not be used when
there are unfavourable road, weather or wind conditions, particularly near accident
black spots.
You must always reduce your speed immedi ately as soon as you detect even just
the slightest swaying of the trailer. On no account attempt to stop the trailer from
“swaying” by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first and then brake firmly . This will avoid brake jolts resulting from
the trailer wheels locking. Shift down gears in good time before negotiating a down-
hill section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a
lengthy slope in a low gear at a high engine speed when the outside temperature is
very high ⇒page 11.
If the needle of the coolant temperature gauge moves into the right-hand area or
even the red area of the scale, reduce yo ur speed immediately. Stop and switch off
the engine if the warning light
 in the instrument cluste r begins flashing. Wait a
few minutes and check the level of coolant in the coolant expansion bottle
⇒ page 215, “Inspecting the coolant level”.
Please refer to the following guidelines ⇒page 28, “Coolant temperature/ Coolant
quantity ”.
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear
and increasing the engine speed is not possible since the fan speed is independent

– Grip with the hand under the radiat or grille and lift up the bonnet.
– Take the bonnet support out of its holder and set it in the opening designed for it ⇒page 209, fig. 196 .
Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the bonnet support into the hold er designed to hold it.
– Allow the bonnet to drop from a height of about 30 cm into the lock - bonnet do not press down on it !
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi ng! Wait long enough until the steam
or coolant has stopped escaping.
•For safety reasons, the bonnet must always be properly closed when
driving. One should therefore check that the lock has in fact engaged prop-
erly after closing the bonnet.
•Stop your vehicle i mmediately while driving if yo u notice that the lock is
not properly engaged and close the bonn et properly - risk of an accident!
Caution
Never open the bonnet using the handle - danger of causing damage.
Working in the engine compartment
Particular care is required when carrying out any work in the engine
compartment!
There is a risk of injuries, scalding, accidents and fire when working in the
engine compartment, e.g. inspecting an d replenishing oil and other fluids. For
this reason, it is essential to comply with the warning instructions stated below and with the general applicable rules of safety. The engine compart-
ment of your car is a hazardous area
⇒ .
WARNING
•Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi ng! Wait long enough until the steam
or coolant has stopped escaping.
•Switch off the engine and pull out the ignition key.
•Apply the handbrake firmly.
•If your vehicle is fitted with a manual gearbox, move the gearshift lever
into Neutral, or if it is fitted with automatic gearbox, move the selector lever
into position P.
•Allow the engine to cool down.
•Keep children clear of the engine compartment.
•Never spill oil and other fluids over the hot engine. Such fluids (e.g. the
antifreeze contained in the coolant) may ignite!
•Avoid short circuits in the electrical system - particularly on the battery.
•Never place your hand into the radiator fan as long as the engine is still
warm. The fan might suddenly start running!
•Never open the cap of the coolant expa nsion bottle as long as the engine
is still warm. The cooling system is pressurized!
•Cover over the cap of the coolant expansion reservoir with a large cloth
when opening it as protection for your face, hands and arms from hot steam
or hot coolant.
•Do not let objects, such as e.g cleaning cloth or tools lie in the engine
compartment.
•If you wish to work under the vehicl e, you must secure the vehicle from
rolling away and support it with suitable supporting blocks: the car jack is
not sufficient for this - risk of injury!
•In cases where it be necessary to carry out inspection work when the
engine is running there is an additional risk from rotating parts (e.g. the V-
ribbed belt, alternator, radiator fan) and from the high-voltage ignition
system. Please observe in addition the following:

Check engine oil level
The dipstick indicates the level of oil in the engine.
Checking the oil level
– Park the vehicle on a horizontal surface.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 210.
– Wait a few minutes and pull out the oil dipstick.
– Wipe off the dipstick with a clea n cloth and insert it again fully.
– Then withdraw the dipstick ag ain and read off the oil level.
Oil level within range
– You must not top up the oil.
Oil level within range
– You may top up the oil. It is possible that the oil level may then be
within range after doing this. Oil level within range
–You
must top up the oil ⇒page 213. It is sufficient, once this is done,
to keep the oil level is within range .
It is normal for the engine to consume oil. The oil consumption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. The oil consumpt ion may be slightly higher than this
during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range if the engine has been
operating at high loads, for example during a lengthy motorway trip during the
summer months, towing a trailer or negotiating a high mountain pass, but not
above this .
The warning light in the instrument cluster* will indicate ⇒page 30, “Engine oil
level* ” whether the oil level is too low. In this case, check the oil level as soon as
possible. Top up with an a ppropriate quantity of oil.
Caution
•The oil level must on no account ex tend beyond the range . Danger of
damaging the catalytic converter.
•Do not continue your journey if for some reason it is not possible under the
conditions prev ailing to top up with oil. Switch of the engine and contact and
obtain professional assistance from a specialist garage.
Replenishing engine oil
– Inspecting the engine oil level ⇒page 213.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 212,
“Engine oil specifications”.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Vehicles exported to countries with a co
ld climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant wh ich offers antifreeze protection down to
about -35°C. In these countries the concentr ation of coolant additive should be at
least 50 %.
Coolant
The cooling system is filled at the works with coolant (purple in colour), which
complies with the specification TL-VW 774 F.
We recommend that you use the same coolant additive - G12 PLUS (purple in
colour).
Please contact your Škoda Service Partner if you have any questions regarding the
coolant or if you wish to fill up with a different coolant.
Your Škoda Service Partner can also suppl y you with the correct coolant additives.
Caution
•Other coolant additives may cause operational problems which, in partic-
ular, involves significantly redu cing the anticorrosion effect.
•Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th is, result in major engine damage.
Inspecting the coolant level
The coolant expansion bottle is located in the engine compartment on
the right.
– Switch the engine off.
– Open the bonnet ⇒ in “Working in the engine compartment” on
page 210.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 199 .
The coolant level when the engine is cold must lie between the
(MIN) and (MAX) markings. The level may also rise slightly above
the (MAX) marking when the engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light
in the instrument cluster  ⇒ page 28. We neve rtheless recommend inspecting
the coolant level directly at the reservoir from time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. You
should not merely top up the coolant in the reservoir. It is also important to have
the cooling system inspected without delay by a specialist garage.
Losses can only occur through the pressure relief in the cap of the coolant expan-
sion bottle which is completely free of leak s if the coolant boils as a result of over-
heating and is forced out of the cooling system.
WARNING
Read and observe the warning notes ⇒page 210, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as soon as possible if the source of over-
heating itself cannot be determined and removed, since there may be grave
damage to the engine.

Inspecting the electrolyte level
The battery is practically maintenance-free under normal operating conditions.
We do, however, recommend that you have the electrolyte level inspected from
time to time by a Škoda Service Partner when outside temperatures are high or
when driving on long trips. You shou ld also check the electrolyte level ⇒page 220
each time the battery is charged.
The battery acid level will also be chec ked as part of the Inspection Service.
Operation in winter
The battery has to provide greater amounts of electricity during the winter. It also
has only part of the initial power output at low temperatures that it has at normal
temperatures.
A discharged battery may already freez e at temperatures just below 0°C.
We therefore recommend that you have the battery checked by a Škoda dealer
before the start of the winter, and recharged if necessary.
WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic
burns. Replace a frozen battery.
Charging the battery
A properly charged battery is essential for reliably starting the
engine.
– Read the warning notes ⇒ in “Working on the battery” on
page 218 and ⇒.
– Switch the ignition and all electrical components off.
– Only for “quick-charging”: Disconnect both battery cables (first of all
“negative”, then “positive”). – Carefully attach the terminal clam
ps of the charger to the battery
terminals (red = “positive”, black = “negative”).
– You can now plug the mains cable of the charger into the power socket and switch on the charger.
– When charging is completed: switch the charger off and unplug the mains cable from the power socket.
– Only then should you disconnect the terminal clamps of the charger.
– Reconnect the cables to the battery (first of all “positive”, then “nega-
tive”).
It is not normally necessary to disconnect the cables of the battery if you recharge
the battery using low amperages (as for example from a mini-charger). Please also
refer to the instructions from the charger manufacturer.
A charging current of 0.1 of the total battery capacity (or lower) is that which should
be used until full ch arging is achieved.
It is, however, necessary to disconnect both cables before charging the battery with
high amperages, so-called “quick-charging ”.
“Quick-charging” a battery is dangerous ⇒ in “Working on the battery” on
page 218. It requires a special charger and appropriate knowledge. We therefore
recommend that you have yo ur battery quick-charged only by your Škoda Service
Par tner.
A discharged battery may already freeze at temperatures just below 0°C ⇒. We
recommend that you no longer use a ba ttery which has thawed out because the
casing of the battery may be cracked thro ugh the formation of ice and this would
allow battery electrolyte to flow out.
The vent plugs of the battery should not be opened for charging.
WARNING
Never charge a frozen or thawed battery - risk of explosion and caustic
burns. Replace a frozen battery.

Disconnecting and reconnecting the battery
On disconnecting and reconnecting the batte ry the following functions are initially
deactivated or are no longer able to operate fault-free.
We recommend having the ve hicle checked by a Škoda Service Partner to ensure
full functionality of all electrical systems.
Replacing the battery
You should only replace a battery with a new battery of the same capacity, voltage
(12 V), amperage and of the same size. Škoda Service Partners have a range of suit-
able batteries available.
We recommend that you only have an old ba ttery disposed of by your Škoda dealer
since it does require special disposal.
For the sake of the environment
Batteries contain poisonous substances such as sulphuric acid and lead. They must
be disposed of in accordance with loca l environmental protection regulations and
on no account as domestic waste.
Windshield washer system
The windshield washer reservoir contains the cleaning fluid for the windscreen or
rear window and for the headlamp cleaning system*. The reservoir is located at the
front right of the engine compartment ⇒fig. 203 .
The filling level of the container is 3 litres, 5.5 li tres on vehicles which also have a
headlight washing system.
Clear water is not sufficient to intensivel y clean the windscreen and headlights. We
therefore recommend using clean washing water together with the screen cleaner
from Škoda genuine accessories (in winter additionally with antifreeze) which is
capable of removing stubborn dirt. Follow the instructions for use on the packaging
when using screen cleaning products.
You should always add antifreeze to the cleaning water in winter even if your
vehicle is fitted with heated windscreen washer nozzles*.
It is also possible in exceptional cases to use methylated spirits when no screen
cleaner with antifreeze is available. The concentration of methylated spirits must
not be more than 15 %. Please note, however, that the antifreeze protection at this
concentration is only adequate down to -5°C.

WARNING
•If you find yourself in flowing traffic switch on the hazard warning lights
system and place the warning triangle on the side of the road at the
prescribed distance from your vehicl e while observing all national legal
provisions. In this way you are protecting not only yourself but also other
road users.
•Never start the engine with the vehicle sitting on the raised jack - danger
of suffering injury!
Caution
If you have to change a wheel on a slope first block the opposite wheel with a stone
or similar object in order to secure th e vehicle from unexpectedly rolling away.
Note
Comply with the national legal regulations.
Changing a wheel
Always change a wheel on a level surface as far as possible.
– Take off the full wheel trim* ⇒page 235 or the caps ⇒page 235.
– In the case of light alloy wheels remove the wheel trim cap ⇒page 236.
– Slacken the wheel bolts ⇒page 236.
– Jack up the vehicle until the wheel to be changed is clear of the ground
⇒ page 237.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper etc.).
– Take off the wheel. – Fit on the spare wheel and tighten the wheel bolts slightly.
– Lower the car.
– Tighten the wheel bolts firmly, al
ternately and diagonally using the
wheel wrench ⇒page 236.
– Mount the full wheel trim/w heel trim cap or the caps.
Note
•All bolts must be clean and must turn easily.
•You must never grease or oil the wheel bolts!
•When fitting on unidirectional tyres, ensure that the tyres rotate in the correct
direction ⇒page 223.
Subsequent steps
After changing the wheel, you must perform the following steps.
– Stow and attach the replaced wheel in the spare wheel well.
– Stow the vehicle tool kit in the space provided.
– Check the tyre pressure on the spare wheel just mounted as soon as
possible.
– Have the tightening torque of the wheel bolts checked with a torque
wrench as soon as possible. Steel and light alloy wheels must be tight-
ened to a tightening torque of 120 Nm.
– Have the defective tyre repaired as soon as possible.
WARNING
It is necessary to observe the guidelines given on ⇒page 225, “New tyres
and wheels” if the vehicle is subseq uently fitted with tyres which are
different to those it was fitted with at the works.

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.
