Recirculated air mode
In recirculated air mode air is sucked out of the interior of the vehicle
and then fed back into the interior.Recirculated air mode prevents polluted ai r outside the vehicle from getting into the
vehicle, for example when driving through a tunnel or when standing in a traffic jam.Switching recirculated air mode on– Press the button page 70, fig. 82 the warning light lights up in the
button.Switching recirculated air mode off– Once again press the button . The warning light in the button goes out.
The recirculated air mode is switched off au tomatically if the air distribution control
is in position
  page 70, fig. 82 . You can also switch recirculated air mode on
again from this setting by re peatedly pressing pushbutton .
WARNING
You should not leave recirculated air mode on over a longer period of time, as
“stale” air may result in fatigue in the dr iver and occupants, divert your attention
and also cause the windows to mist up. Th e risk of having an accident increases.
Switch recirculated air mode off as soon as the windows begin misting up.Using the air conditioning system economicallyThe compressor on the air conditioning system uses power from the engine when
in cooling mode which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the interior
has been strongly heated through the effect of direct sunlight in order to allow the
heated air to escape.
The cooling system should not be switched on while travelling when the window is
open.
The desired interior temperature can also be achieved without switching in the
cooling system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.Operational malfunctionsIf the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be:•
The fuse on the air conditioning system has blown. Check the fuse, replace it if
necessary page 156.
•
The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot page 16.
If you are not able to rectify the operat ional problem yourself, or if the cooling
capacity decreases, switch the cooling system off. Contact a specialist garage.

Towing a trailer
118
Towing a trailerTowing a trailerTechnical requirementsYour vehicle is designed primarily for tr ansporting persons and luggage. It can,
however, also be used for towing a trailer - provided certain technical equipment is
fitted.
If your vehicle has already been supplied with a factory-fitted towing device then
everything that is necessary for towing a tr ailer in technical terms, and in terms of
the law, has already been taken into account.
Your vehicle is fitted with a 13-pin power socket for the electrical connection
between the vehicle and trailer. If th e trailer which you wish to tow has a 7-pin
connector , you can use a suitable adapter
6) from Škoda original accessories.
This work must be carried out in accordance with the manufacturer's specifications
if a towing device is retrofitted.
Authorised Škoda Service Partners can pr ovide information about retrofitting a
towing device and for any necessary modifications to the cooling system.
WARNING
We recommend that you have the towing de vice from Škoda original accessories
installed by an authorised Škoda Service Partner. He is familiar with all the rele-
vant details relating to retrofitting such equipment. There is a risk of an accident
if the towing device is not properly fitted!General MaintenanceTrailer load
The permissible trailer load must on no account be exceeded.
You can negotiate appropriately steeper inclines and descents if you do not make
full use of the permissible trailer load.
The trailer loads specified only apply for altitudes up to 1 000 metres above mean
sea level. The fact that the engine power output drops with increasing height due
to a lowering of air pressure and thus th e ability to climb, means that the towed w e i g h t m u s t b e r e d u c e d b y 1 0 % f o r e v e r y f u r t h e r i n c r e a s e o f 1 0 0 0 m e t r e s i n h e i g h t
above sea level. The towed weight is the weight of the (laden) vehicle and the
(laden) trailer together. One should take
this into account before driving up to
higher altitudes.
The trailer and drawbar load information on the type plate of the towing device
are merely test data for the towing device The data relating to your vehicle, which
is often less than this test data, can be found in your vehicle registration docu-
ments.
Distribution of the load
Distribute the load in the trailer in such a way that any heavy items are located as
close as possible to the axle. Secure the items to prevent them slipping.
Tyre inflation pressure
Select the tyre inflation pressure on your vehicle for that of “fully laden”,
 page 141. The inflation pressure of the tyre s fitted to the trailer adjust in accord-
ance with the manufacturer's recommendation.
Exterior mirrors
You have to have additional exterior mirr ors fitted if you are not able to see the
traffic behind the trailer with the standard rear-view mirrors. Both exterior mirrors
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 41.
Detachable ball head
The ball rod is detachable on vehicles wh ich feature a factory-fitted towing device.
Further information on the towing device page 119.
Note
•
We recommend that you also have your vehicle inspected between service
intervals if you tow a trailer frequently.
•
The handbrake on the towing vehicle must be put on when coupling and decou-
pling the trailer.
6)In some countries the adapter is supplied with the towing device.s2lk.2.book Page 118 Monday, April 18, 2011 7:41 AM

Technical Data
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 temperatur e 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
combination.
Driving speed
Do not drive faster than 80 km/hour for sa fety 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
downhill section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temper ature 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 16, “Engine coolant temperature Display”.
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 cluster begins flashing. Wait a
few minutes and check the level of coolant in the coolant expansion bottle
 page 134, “Inspecting the coolant level”. Please refer to the following guidelines 
page 25, “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 the slope without any drop in speed.
Detachable towing device*The ball head of the towing device is stow ed together with separate fitting instruc-
tions in the spare wheel well in the luggage compartment of the vehicle.
Inspect the ball head to ensure that it is properly locked each time before setting
off. The inspection is performed by turning the closed locking lever downwards. If
the locking lever can only be turned around a small angle (approx. 5°), the locking
mechanism is O.K. After the inspection pull the locking lever back again to its stop.
The towing device must not be used, if it does not wish to close or the locking lever
turns slightly in the closed position.
WARNING
Do not use any aids or tools for installing or removing the ball head. This might
result in damage to the locking mechanism to the extent that the safety of the
towing device is no longer assured - risk of an accident.
Note
•
Do not carry out any modifications or re pairs to the ball head or to any other
components on the towing device.

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 replen ishing 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 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.
•
Move the gear lever into the Neutral position.
•
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 expans ion 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. cle aning 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 additi onal 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: −
Never touch the electrical cables of the ignition system.
− Absolutely avoid any jewellery, loose items 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 fuel system or on the electrical system:
− Always separate the car batter y from the electrical system.
− Do not smoke.
− Never carry out any work close to naked flames.
− Always keep a working fire extinguisher at hand.Caution

page 166, “Engine oil
specifications”.
– Inspect the oil level page 132.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING
•
Avoid dripping oil onto hot parts of the engine when topping up will oil - a
risk of fire!
•
Read and observe the warning notes page 131, “Working in the engine
compartment” before working in the engine compartment.For the sake of the environment
The oil level must on no account extend beyond the range  page 132. Oil will
otherwise be drawn in through the crankc ase ventilation and may pass through the
exhaust system to atmosphere. The oil ma y combust in the catalytic converter and
damage it.Changing engine oilThe engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator page 17, “Service Interval Display”.
WARNING
•
Only carry out the engine oil change, if you have the required professional
knowledge!
•
Read and observe the warning notes page 131, “Working in the engine
compartment” before working in the engine compartment.
•
First of all, let the engine cool down, wear an eye protection and gloves - risk
of caustic burns due to hot oil.Caution
You must not pour any additives into the engine oil - risk of engine damage!
Damage, which results from such produc t, are excluded from the warranty.
For 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 properly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you
have the oil and oil filter change carried out by an authorised Škoda Service Partner.Note
After your skin has come in contact with the oil, you must thoroughly wash your
skin.Cooling systemCoolant
The job of the coolant is to cool the engine.The cooling system does not require any maintenance under normal operating
conditions. 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 months 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 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 factory-filled with coolant (purple in colour), which complies
with the specification TL-VW 774 G.
We recommend that you use the same cool ant additive - G12 PLUS-PLUS (purple in
colour) for topping up the system.
Please contact an authorised Škoda Serv ice Partner if you have any questions
regarding the coolant or if you wish to fill up with a different coolant.

Coolant quantity
Caution
•
Other coolant additives may cause operational problems which, in particular,
involves significantly reduci ng the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss of coolant
and, as a consequence of this, re sult 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 page 130. – Check the level of coolant in the coolant expansion bottle 
fig. 124. 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 25, “Coolant temperature/coolant level  ”. 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 re servoir. 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 leaks 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 131, “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.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. 124 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 the system, must comply with one
specific specification  page 133. Do not use an altern ative additive if the coolant
additive G13 is not available in an emergency. Just top up the system with water and

Technical Data
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 fill up over the “MAX” marking! Exce ss coolant which is heated up is forced
out of the cooling system through the pressu re 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.
WARNING
•
The cooling system is pressurized! Do not open the cap of the coolant expan-
sion bottle if the engine is still hot - risk of scalding!
•
The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the health.
It is important, therefore, to always safely store any coolant additive in its orig-
inal container out of the reach of children - risk of poisoning!
•
If any splashes of coolant get into your eyes, rinse out your eyes immediately
with clear water and contact a doctor as soon as possible.
•
You should also consult a doctor wi thout delay if you have inadvertently
swallowed coolant.Caution
Do not continue your journey if for some reason it is not possible under the condi-
tions prevailing to top up with coolant. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe engine
damage.
For the sake of the environment
Do not re-use coolant if it is necessary to drain the coolant in the system. It should
be collected and disposed of in comp liance with environmental protection
regulations.Radiator fan
The radiator fan may switch on suddenly.The radiator fan is driven by an electric motor and controlled according to the
coolant temperature. The radiator fan may continue running for up to 10 minutes after the engine has
been switched off - even if the ignition is also off. It may also switch on suddenly
after a certain time, if
•
the coolant temperature has risen beca
use of an accumulation of heat or
•
the warm engine compartment is heated up additionally by strong sunlight.
WARNING
You must therefore be aware when workin g in the engine compartment that the
fan may switch on suddenly - risk of injury!Brake fluidInspecting the brake fluid levelThe brake fluid reservoir is located on the left of the engine compartment. The
brake fluid reservoir on right-hand steering models is positioned on the other side
of the engine compartment.
– Switch the engine off.
– Open the bonnet page 130.
– Inspect the brake fluid level in the reservoir fig. 125 . The level must be
between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear and
automatic adjustment of the brak e pads, and is perfectly normal.
There may be an indication of a leak in the brake system, however, if the fluid level
drops significantly within a sh ort time or if it drops below the “MIN” marking. If the
