Technical Data
The AC compressor is switched off at a hi
gh coolant temperature in order to provide
cooling at a high load of the engine.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle be low the vehicle. This is quite normal and
not an indication of a leak!
If you make a change before switching off the ignition, which differs from the auto-
matic mode, the changed functi ons remain stored. Only the function “circulating air”
is erased 20 minutes after switching off the ignition.
Recommended setting for all periods of the year:

Set the temperature to 22 °C (72 °F).

Press the button page 83, fig. 97.

Move the air outlet vents 3 and 4, so that the air flow is directed slightly upwards
 page 77, fig. 94 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons 17 and 9 page 83, fig. 97 . The information
in the desired temperature measuring unit appears in the display.
WARNING

For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin g. Please familiarize yourself about
how to correctly operate th e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.

You should not leave recirculated air mode on over a longer period of time,
as “stale” air may result in fatigue in the driver and occupants, divert your
attention and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mode off as soon as the windows begin
misting up.Note

If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of deposits. Switch the cooling system on at
least once a month for approximately 5 minut es at the highest blower stage - also during the cold season of the year - in order to avoid such odours. Also open a window
for a short time.

We recommend that you do not smoke in
the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the interior
of the vehicle forms deposits in the evapor ator of the air conditioning system. This
produces a permanent odour when the air conditioning system is operating which can
only be eliminated through considerable effort and expense (replacement of
compressor).

The used air streams out through the air removal openings in the luggage compart-
ment.

WARNING

Never run the engine in non ventilated 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 unconsciousness and
death.

Never leave your vehicle unattended with the engine running.Caution

The starter may only be operated (ignitio n key position ), if the engine is not
running. If the starter is immedi ately 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 converter 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 emis-
sions are lower.Petrol enginesThese engines are fitted with a starter system which selects the correct fuel-air mixture
for every external air temperature.
Do not depress accelerator before 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 electric al fuel pump is defect if the engine still
does not start. Check the fuse and replace it if necessary page 177.

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 enginesGlow 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 tempera-
ture.
The preglow indicator light
 comes on after the ignition has been switched on.
You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.

You should start the engine immediately after the glow plug warning light
 has
gone out.

The glow plug warning light will come on for about one second if the engine is at a
normal operating temperature or if the outside temperature is above +5°C. This
means that you can start the engine right away.

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 diesel preglow system is defect if the engine still
does not start. Check the fuse and replace it if necessary page 177.

Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank has
run completely dry - up to one minute. This is because the fuel system must first of all
be filled while the attempting to start the engine.
Switching off the engine– The engine can be switched off by tu rning the ignition key into position
 page 87, fig. 100 .

Starting-off and Driving
90WARNING

Never switch off the engine before the ve hicle is stationary - risk of accident!

The brake booster only operates when the engine is running. Greater phys-
ical effort for braking is required when en gine is switched off. Because if you do
not stop as normal, this can cause an accident and severe injuries.Caution
you should not switch the engine off right away at the end of your journey after the
engine has been operated for a lengthy period at high loads but should be allowed it
to run at idling speed for about 2 minutes. This prevents any accumulation of heat
when the engine is switched off.
Note

The radiator fan may continue running fo r a further 10 minutes or so after the
engine and the ignition have been switched off. The coolant fan may, however, also
switch on again after some time if the co olant temperature rises because of an accu-
mulation of heat in the engine or if the engine is warm and the engine compartment is
additionally heated by strong sunlight.

This is why particular care is required when carrying out any work in the engine
compartment  page 148, “Working in the engine compartment”.
Shifting
Shift into reverse only when the vehicle is stationary. Depress the clutch pedal and
hold it fully depressed. Wait a moment before engaging reverse gear in order to avoid
any shift noises.
The reversing lights will come on once reverse gear is engaged, provided the ignition
is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note

One should not lay the hand on the shift lever while driving the vehicle. The pres-
sure of the hand will be transferred to the gearshift forks in the gearbox. This can, over
a period of time, lead to earl y wear of the gearshift forks.

Depress the clutch pedal fully when changi ng gears, in order to avoid unnecessary
wear and damage.
HandbrakeApplying the handbrake– Pull the handbrake lever up fully.

Technical Data
Headlights
Before starting off with a hitched trailer, also check the setting of the headlights. Alter
the setting as necessary with the ai
d of the headlight beam adjuster page 48.
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 136.
Note

We recommend that you also have your vehicle inspected between service inter-
vals if you tow a trailer frequently.

The handbrake on the towing vehicle must be put on when coupling and decou-
pling 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 temperature 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 combina-
tion.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for countries
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 cond
itions, particularly near accident black
spots.
You must always reduce your speed immediat ely 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 downhill
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 engi ne speed when the outside temperature is
very high  page 16.
If the needle of the coolant temperature gauge moves into the right-hand area or even
the red area of the scale, reduce your speed immediately. Stop and switch off the
engine if the warning light
 in the instrument cluster begins flashing. Wait a few
minutes and check the level of coolant in the coolant expansion bottle page 153,
“Inspecting the coolant level”.
Please refer to the following guidelines  page 28, “Coolant temperature/coolant
level ”.
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 of the
engine speed. One should also not drop a gear for this reason when towing a trailer as
long as the engine can manage th e slope without any drop in speed.

Closing the bonnet
– Lift the bonnet slightly and unhook the bonnet support. Press the bonnet support
into the holder 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 scalding! 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 properly
after closing the bonnet.

Stop your vehicle immediately while drivin g if you notice that the lock is not
properly engaged and close the bonnet properly - risk of an accident!
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, acci dents and fire when working in the engine
compartment, e.g. inspecting and 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 safe ty. The engine compartment 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 scalding! 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.

On vehicles fitted with a manual gea rbox, move the gearshift lever into
Neutral.

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 anti-
freeze 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 expans ion 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 lifting 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 fr om rotating parts (e.g. the V-ribbed belt,
alternator, radiator fan) and from the high-voltage ignition system. Please
observe in addition the following:
Never touch the electrical cabl es of the ignition system.
 Absolutely avoid any jewellery, loose it ems of clothing or long hair from
getting into the rotating parts of the engine - Hazard! Therefore remove any
jewellery beforehand, tie up your hair and wear tight fitting clothing.

Please also comply with the warnin g instructions stated below when
carrying out any essential work on the fu el system or on the electrical system:
 Always separate the car battery from the electrical system.

use throughout the year - except in extreme climatic regions.
You can mix various oils together with each ot her when refilling with oil. This does not,
however, apply for models with flexible service intervals (QG1).
Engine oils are, of course, undergoing co ntinuous further development. Thus the
information stated in this Owner's Manual is only correct at the time of publication.
Authorised Škoda Service Partners are informed by Škoda Auto about current changes.
This why you should always have engine oi l changed by an authorised Škoda Service
Par tner.

Inspecting and replenishing
152For the sake of the environment

You must on no account pour oil into the ground or into the sewage system.

In view of the problems involved in prop erly disposing of old oil, the material,
equipment and the knowledge required for such work, we recommend that you have
the oil and oil filter change carried out by a specialist garage.Note
After your skin has come in contact with th e oil, you must thoroughly wash your skin.Power steeringThe reservoir for hydraulic oil of power steering is located in the front right of the
engine compartment page 149, fig. 145 .
Check hydraulic oil
The hydraulic system of the power steering is filled with the hydraulic oil designated in
the catalogue as G 002 000.
Perform the inspection of the hydraulic oil level when the engine is cold and not
running.
The hydraulic oil level must be be tween the “MIN” and “MAX” markings fig. 147 . If
the level drops below the marking “MIN”, it is necessary that the power steering is
checked by a specialist garage. It is not su fficient to solely refill with hydraulic oil.
Note
If the engine is not running (when towing) or if the V-ribbed belt is torn, the power
steering does not operate. The vehicle is fully steerable however. There is however
increased force required to turn the steering wheel.Cooling systemCoolant
The job of the coolant is to cool the engine.The cooling system does not require any maintenance under normal operating condi-
tions. The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture not only provides antifreeze prot ection down to -25°C but also protects
the cooling and heating system from corrosion. It also prevents the formation of scale
and significantly increases the boiling point of the coolant.
You must therefore not reduce the concentration of antifreeze agent in the coolant by
adding water, also not during the summer mont hs or in countries with a warm climate.
The concentration of coolant additive in the coolant must be at least 40%.
You can increase the amount of antifreeze in the coolant if a higher concentration of
antifreeze is necessary for climatic reasons but only up to 60% (antifreeze protection
down to approx. -40°C). The antifreeze protection tails off above that concentration.
Vehicles exported to countries with a cold climate (e.g. Sweden, Norway, Finland) are
already factory-filled with a coolant which of fers antifreeze protection down to about
-35°C. In these countries the concentration of coolant additive should be at least 50%.
Coolant
The cooling system is factory- filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the same coolan t additive - G13 (purple in colour) - for
topping up the system.
Please contact a specialist garage if you have any questions regarding the coolant or if
you wish to fill up with a different coolant.
A specialist garage can also supply yo u with the correct coolant additives.

Caution

Other coolant additives may cause operational problems which, in partic-
ular, involves significantly reducing the anticorrosion effect.

Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequence of this, result in major engine damage.
Inspecting the coolant levelThe 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 148.
– Check the level of coolant in the coolant expansion bottle fig. 148 . When the
engine is cold, the coolant level must lie between the and markings. When
the engine is warm, the level may also lie slightly above the hatched part.
If the coolant level in the reservoir is too lo w, this is indicated by the warning light in
the instrument cluster
  page 28. We nevertheless 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 expansion
bottle which is completely free of leaks if the coolant boils as a result of overheating
and is forced out of the cooling system.
WARNING
Read and observe the warning notes page 148, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as s oon as possible if the source of overheating
itself cannot be determined and removed, since there may be grave damage to the
engine.Replenishing the coolant– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir fig. 148 and
unscrew the cap carefully by turning it to the left .
–Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing th e system, must comply with one specific
specification page 152, “Coolant”. Do not use an al ternative additive if the coolant
additive G13 is not available in exceptional cases. Just top up the system with water
and as soon as possible arrange adjustment to correct the mixing ratio of water and
coolant additive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not top up the fluid above the hatched pa rt! Excess coolant which is heated up is
forced out of the cooling system through th e pressure relief valve in the cap of the
coolant compensation bottle.
Wait until the engine has cooled down for a system which has suffered a major loss of
coolant before pouring in coolant. This is necessary to avoid engine damage.
