Auto Check Control*
Car state
The Auto Check Control carries out a check of certain functions and vehicle compo-
nents. The check is performed constantly when the ignition is switched on, both
when the vehicle is stationary, as well as when driving.
Operational faults, urgent repairs, service work or other information appear in the
display of the instrument cluster. The disp lays are shown with a red or yellow light
symbol depending on the priority of the message.
The red symbols indicate danger (priority 1) while the yellow symbols indicate a
warning (priortity 2). Information for the driver may also appear in addition to the
symbols ⇒page 24.
There is at least one error message to be read when the term Vehicle status is
flashing in the main menu. After selecting this menu the first of the error messages
is displayed. If there are several error messages, they are shown on the display
under the message e.g. 01/03 ⇒ fig. 15 . This display indicates that the first of a total
of three error messages should be displa yed. The respective symbols light up one
after the other in an interval of 5 seconds. Investigate the displayed faults as soon
as possible.
As long as the operational faults are not rectified, the symbols are always indicated
again. After the first display, the symbols are indicated without information for the
driver. If a fault occurs, a warning signal will also sound in addition to the symbol and text
in the display:
•Priority 1 - three warning signals
•Priority 2 - one warning signal
Red symbols
A red symbol signals danger.
Proceed as follows if a red symbol is displayed:
– Stop the vehicle.
– Switch the engine off.
– Investigate the function indicated.
– Obtain professional assistance.

Starting-off and Driving
118
Starting the engine
General
You can only start the engine only using an original ignition key.
•Place the gearshift lever into neutral (or place the selector lever to the position
P or N in the case of an automatic gearbox) and put on the handbrake firmly before
starting the engine.
•The clutch pedal should be fully depressed when starting the engine which
means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be damage
to the starter.
The engine running noises ma y louder at first be louder for a short time after
starting the cold engine until oil pressure can be built up in the hydraulic valve
clearance compensation. This is quite no rmal and is not an operating problem.
If the engine does not start ...
You can use the battery of anothe r vehicle as a jump-start aid ⇒page 238.
It is only possible to tow-start vehicles fitted with a manual gearbox. The tow-
starting distance must not be more than 50 metres ⇒page 242.
WARNING
•Never run the engine in non ventilat ed or enclosed areas. The exhaust
gases of the engine contain besides the odorless and colourless carbon
monoxide a poisonous gas - hazard! Carbon monoxide can cause uncon-
sciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), if the engine is not
running. If the starter is immediately operated after switching off the engine, the
starter or the engine can be damaged.
•Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its normal oper ating temperature - risk of damaging the
engine!
•Vehicles which are fitted with an exhaust gas catalytic conver ter should not be
tow-started over a distance of more than 50 metres.
For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the
pollutant emissions are lower.
Petrol engines
These engines are fitted with a starter system which selects the correct fuel/air
mixture for every external air temperature.
•Do not operate accelerator befo re and when starting engine.
•Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.
•It is possible that the fuse on the electrical fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary ⇒page 243.
•Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator
after the engine has started.
Diesel engines
Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside temper-
ature.
The preglow indicator light
comes on after the igniti on has been switched on.

WARNING
Even with this additional function the vehicle cannot be steered automati-
cally! The driver is furthermore fully reponsible for the steering of the
vehicle!
Brakes
What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions
of the vehicle and your style of driving. Particularly if you drive a great deal in towns
and over short distances or if you adopt a sporty style of driving, it may be neces-
sary to have the thickness of the brake pads inspected at a specialist garage
between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain condi-
tions such as when driving through water, during heavy rain showers or after the
vehicle has been washed in an automatic vehicle wash, since the brake discs and
brake pads may be moist or even have a coating of ice on them in winter. You
should dry the brakes as soon as possib le (by applying and releasing the brakes
several times, if the road conditions and the traffic situation allows it).
There also may be a certain delay before the full braking efficiency is available when
driving on roads which have been treated wi th road salt if you have not used the
brakes for some considerable time beforeha nd. The layer of salt on the brake discs
and brake pads must first be rubb ed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on th e bake pads occur if the vehicle has been
parked for a long period and if you do not make much use of the braking system.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro-
sion is present ⇒. Faults in the brake surface
If you notice that the braking distance
has suddenly become longer and that the
brake pedal can be depressed further, it is possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist garage
without delay in order to have the problem rectified. Drive at a reduced speed while
on your way to the dealer and adapt your style of driving to the higher brake pedal
pressure required.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The
level of the brake fluid is monitored electronically ⇒page 32, “Brake system ”.
WARNING
•Only apply the brakes for the purpos e of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users
in jeopardy.
•When retrospectively mounting a front spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced
otherwise the braking sy stem could run too hot.
•Allow for the fact that new brake pads do not achieve their full braking
efficiency until approximately 200 kilo metres. New brake pads must be first
“run in” before they develop their optimal friction force. You can, however,
compensate for this slightly reduced braking force by increasing the pres-
sure on the brake pedal. This guidelin e also applies to any new brake pads
installed at a future date.
Caution
•Never allow the brakes to ru b by applying slight pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a longer
braking distance and excessive wear.
•Before negotiating a steep downhill sect ion, please reduce your speed, shift
down into the next lower gear (manual ge arbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of the

Taking care of your vehicle and cleaning the vehicle
200
Automatic vehicle wash systems
The paintwork of the vehicle is sufficiently resistant that the vehicle can be washed
normally in automatic vehicle wash plants without any problem. The actual stress
to which the paintwork is subjected, however, depends greatly on the design of the
vehicle wash system, the filtering of the water and the type of washing and care
products used. If the paintwork of your vehicle appears mat after being washed or
even has scratches, point this out to the operator of the vehicle wash plant. Use a
different vehicle wash plant, if necessary.
There are no particular points to note be fore washing your vehicle in such a plant
other than the usual precautionary measur es (closing windows and sliding/tilting
roof, moving any factory-fitted aerials down flat against the bodywork, etc.).
If you have any particular atta ch e d p a r t s f i t te d t o y o u r c a r - s u ch a s s p o i l e r, ro o f ra ck
system, two-way radio aerial - it is best to first of all consult the operator of the car
wash plant.
It is important to degrease the lips of the windscreen wiper rubbers after passing
through the automatic vehicle wash system.
Caution
Do not screw the swivelling down roof aeri al tight before washing the vehicle in an
automatic vehicle wash sy stem - risk of damage!
Washing vehicle by hand
It is important to first soften the dirt with plenty of water and rinse it off as thor-
oughly as possible before wa shing your vehicle by hand.
One should then clean the vehicle using a soft washing sponge, washing glove or
a washing brush and only slight pressure. Work from the top to the bottom -
beginning with the roof. Only place slight pressure on the vehicle paintwork during
cleaning Only use a car shampoo for stubborn dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such areas. Rinse off the vehicle well after giving it a wash and dry it off using a chamois leather.
WARNING
•The ignition should always be switched off when you wash your vehicle -
risk of accident!
•Protect your hands and arms from sharp-edged metal parts when you
are cleaning the underfloor, the inside of the wheel housings or the wheel
trims - risk of cuts.
Caution
•Do not wash your vehicle in bright sunlight - risk of paint damage.
•Ensure that the jet of water is not aimed directly at the locks or at the door and
panel joints if you spray your vehicle in winter down with a hose - risk of freezing.
•Do not use any insect sponges, rough ki tchen sponges or similar cleaning prod-
ucts - risk of damage to the surface of paintwork.
For the sake of the environment
Only wash your vehicle at washing bays specifically reserved for this purpose. This
ensures that no water which may be cont aminated by oil flows into the sewage
system. It is not even permitted to wash your vehicle in certain areas except at such
specific washing bays.
Washing with a high-pressure cleaner
When you wash your vehicle with a high-pressure cleaner, it is essential to comply
with the instructions for use of the cleaning equipment. This applies in particular to
the pressure used and to the spraying distance . Maintain a sufficiently large
distance to soft materials such as rubber hoses or insulation material.
On no account use circular spray nozzles or so-called dirt cutters!

Inspecting and Replenishing215
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.

Wheels and Tyres
Wheels
General comments
•New tyres do not offer optimal grip at first and should therefore be run in for
about 500 km at a moderate speed and an appropriately cautious style of driving.
You will also profit from longer tyre life.
•The tread depth of new tyres may differ because of design features and the
configuration of the tread (depending on the type of tyre and the manufacturer).
•Drive over curbs on the side of the road and other such obstacles slowly and,
where possible, at a right angles in order to avoid damage to tyres and wheel trims.
•Inspect your tyres from time to time for damage (punctures, cuts, splits and
bulges). Remove foreign bodies from the tyre profile.
•Damage to tyres and wheels is frequent ly not visible. Unusual vibrations or
pulling of the vehicle to one side could be a sign of tyre damage. Please reduce
your speed immediately and stop if you suspect that a wheel is damaged.
Inspect the tyres for signs of damage (bulge s, splits, etc.) If no visible damage is
present, please drive at an appropriatel y slow speed and carefully to the nearest
specialist garage in order to have your vehicle inspected.
•Also protect your tyres from contact with oil, grease and fuel.
•Immediately replace any dust caps of the valves which have got lost.
•Mark wheels before removing them so th at their previous direction of running
can be maintained when mounted them again.
•Always store wheels or tyres which been removed in a cool, dry and, where
possible, dark place. Tyres which are not fixed to a wheel trim should be stored
upright.
Unidirectional tyres*
The direction of rotation of the tyres is marked by arrows on the wall of the tyre. This
indicates the direction of rotation of the tyre, and it is essential that the tyres are
fitted on to run in this direction. Only then are the tyres able to provide the optimal
properties in terms of grip, low noise, wear-and-tear and aquaplaning. Further information concerning
the use of unidirectional tyres ⇒page 227.
WARNING
•New tyres during the first 500 km do not offer optimal grip and should
therefore be run appropriately - risk of accident!
•Never drive with damaged tyres - risk of accident!
Note
Please observe the various differing legal requirements regarding tyres.
Tyre life
The life of your tyres very much depends on the following points:
Tyre pressure
The working life of tyres will be shortened considerably if the tyres are insufficiently
or over-inflated and this will have an adverse effect on the handling of your vehicle.
Correctly inflated tyres are of partic ular importance when travelling at high speeds.
It is therefore good to check the pressure at least once a month and also before

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.
