The air conditioning system
Air conditioning system
Introductory information
The heating effect is dependent upon the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
If the cooling system is switched on, the temperature and air humidity drops in
the vehicle. The well-being of the occupants of the car is enhanced as a result of
this particularly at high outside temperatures and a high air humidity. The system
prevents the windows misting up during the cold season of the year.
It is possible to briefly activate recirculated air mode to enhance the cooling ef-
fect.
Please refer to the information regarding recirculated air mode for the air-condi-
tioning system » page 96 or for Climatronic » page 98 .
The air inlet in front of the windscreen must be free of ice, snow or leaves to en-
sure that the heating and cooling system operates properly.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle below the vehicle. This is quite normal
and not an indication of a leak! WARNING
■ For your own safety and that of other road users, ensure that all the win-
dows are free of ice, snow and misting. Please familiarize yourself about how
to correctly operate the heating and ventilation systems, how to demist and
defrost the windows, as well as with the cooling mode.
■ Do not leave recirculated air mode on over a longer period of time, as “stale”
air can cause fatigue of the driver and passengers, reduce attention levels and
also cause the windows to mist up. The risk of having an accident increases.
Switch off recirculated air mode as soon as the windows start to mist up. Note
■ The used air streams out through the vents in the boot.
■ 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 in-
terior of the vehicle forms deposits in the evaporator of the air conditioning sys-
tem. This produces a permanent odour when the air conditioning system is oper-
ating which can only be eliminated through considerable effort and expense (re-
placement of compressor). ■ To ensure that the air conditioning system works properly, do not block up the
air outlet vents with any objects. Ð Using the air conditioning system economically
The 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 inte-
rior has been strongly heated through the effect of direct sunlight in order to al-
low the heated air to escape.
The cooling system should not be switched on while travelling when the window
is open.
If the desired interior temperature can also be achieved without activating the
cooling system, fresh air mode should be selected. For the sake of the environment
Pollutant emissions are also reduced when fuel is saved. Ð Operational problems
If 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.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry »
page 207.
› The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot » page 9.
If you cannot rectify the functional fault yourself, or the cooling capacity decrea-
ses, the cooling system must be switched off. Visit a ŠKODA specialist garage. Ð

switched on, the air distribution control will temporarily be switched off. If the
concentration of pollutants decreases to the normal level, the air distribution con-
trol is automatically switched off so that fresh air can be guided into the vehicle
interior. In recirculated air mode air is sucked out of the interior of the vehicle and
then fed back into the interior. When the automatic air distribution control is
switched on, an air quality sensor measures the concentration of pollutants in the
drawn in air.

Direct switching on/off 101
System settings 101
Radio remote control 101
Changing the battery of the radio remote control 102
Auxiliary heating (parking heating)
The auxiliary heating (auxiliary heating) functions in connection with the air-con-
ditioning system or Climatronic.
It can be used when stationary, when the engine is switched off to preheat the
vehicle and while driving (e.g. during the heating phase of the engine).
The engine is also preheated, if the auxiliary heating is switched on when the ve-
hicle is stationary and the engine is switched off. This is not valid for vehicles with
the 3.6 l/191 kW
FSI engine.
The auxiliary heating (parking heating) warms up the coolant by combusting fuel
from the vehicle tank. The coolant warms up the air, which (if the blower speed is
not set to zero) flows into the passenger compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun). WARNING
■ The auxiliary heating must never be operated in closed rooms - risk of poi-
soning! ■ The auxiliary heating must not be running during refuelling - risk of fire.
■ The exhaust pipe of the auxiliary heating is located on the underside of the
vehicle. Therefore, if you wish to operate the auxiliary heating, do not park the
vehicle in such a way that the exhaust gases from the auxiliary heating can
come into contact with highly flammable materials (e.g. dry grass) or easily in-
flammable substances (e.g. spilt fuel). Note
■ If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
The auxiliary heating automatically controls the filling level in the fuel tank. If only
a low quantity of fuel is present in the fuel tank, the function of the auxiliary
heating is blocked. ■ The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
■ If the auxiliary heating and ventilation is running, the vehicle battery discharges.
If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometres in order to recharge
the vehicle battery.
■ The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.
■ At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating
problem.
■ After switching off the auxiliary heating, the coolant pump runs for a short peri-
od.
■ The auxiliary heating and ventilation does not switch on or comes on, if the ve-
hicle battery indicates a low loading state » page 186, Automatic load deactiva-
tion .
■ The auxiliary heating (parking heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please re-
fuel! ■ The air inlet in front of the windscreen must be free of ice, snow or leaves in
order to ensure that the auxiliary heating operates properly.
■ So that warm air can flow into the vehicle interior after switching on the auxili-
ary heating, you must maintain the comfort temperature normally selected by
you, leave the fan switched on and leave the air outlet vents in an open position.
It is recommended to put the air flow in the position or . Ð

If the battery is properly charged, the effective range is up to 600
m. To switch
on/off the auxiliary heating, hold the radio remote control vertically with the an-
tenna A
» Fig. 111 facing upwards. The antenna must not be covered with the fin-
gers or the palm of the hand during this process. Obstacles between the radio re-
mote control and the vehicle, bad weather conditions and a weaker battery can
clearly reduce the range.
The auxiliary heating can only be switched on/off safely using the radio remote
control, if the distance between the radio remote control and the vehicle is at
least 2 m.
Warning light in the radio remote control
The indicator light in the radio remote control C
» Fig. 111 indicates after a key-
stroke if the remote control signal was received by the auxiliary heating and if the
battery is adequately charged.

The radio remote control comprises electronic components and must therefore be
protected against water, severe impacts and direct sunlight. Ð Changing the battery of the radio remote control
First read and observe the introductory information and safety warn-
ings on page 100.
If the indicator light on the radio remote control indicates a weak or discharged
battery,
C
» Fig. 111 on page 101, it must be replaced. The battery is located under
a cover B
» Fig. 111 on page 101 on the back of the radio remote control.
› Insert a flat, blunt object, such as a coin, into the gap on the battery cover, turn
the cover in the opposite direction of the arrow up to the mark and unlock it.
› Change the battery, replace the battery cover and lock it by moving it in the di-
rection of the arrow. For the sake of the environment
Dispose of the old battery in accordance with environmental regulations. Note
■ Pay attention to the correct polarity when changing the battery.
■ The replacement battery must have the same specification as the original bat-
tery. Ð ä

■ Never adjust the steering wheel when the vehicle is moving only when the
vehicle is stationary! ■ Maintain a distance of 25 cm 1
to the steering wheel
» Fig. 112 on page 104
- . Not maintaining this minimum distance will mean that the airbag system
will not be able to properly protect you - hazard!
■ The lever for adjusting the steering wheel must be locked whilst driving so
that the position of the steering wheel cannot accidently change during the
journey - risk of accident!
■ If the steering wheel is adjusted further towards the head, the protection
provided by the driver airbag in the event of an accident is reduced. Check
that the steering wheel is aligned to the chest. ■ When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock position. Never hold the steering wheel in
the 12 o'clock position or in any other way (e.g. in the middle or inner edge of
the steering wheel). In such cases, you could severely injure the arms, hands
and head when the driver airbag is deployed. WARNING (Continued)
■ When driving, the ignition key must always be in the position 2
» Fig. 113
on
page 105 (ignition switched on) without the engine running. This position is
indicated by the indicator lights coming on. If this is not the case, it could re-
sult in unexpected locking of the steering wheel - risk of accident! ■ Only pull the ignition key from the ignition lock when the vehicle has come
to a complete stop (by applying the handbrake). Otherwise the steering wheel
could block - risk of accident! ■ When leaving the vehicle, the ignition must always be removed. This is par-
ticularly important if children are left in the vehicle. Otherwise the children
could, for example, start the engine - risk of accident or injury! ■ Never leave the engine running in unventilated or closed rooms. The ex-
haust gases of the engine contain besides the odorless and colourless carbon
monoxide a poisonous gas - hazard! Carbon monoxide can cause unconscious-
ness and death. ■ Never leave the vehicle unattended with the engine running.
■ Never switch off the engine before the vehicle is stationary - risk of acci-
dent! CAUTION
■ The starter may only be operated (ignition key position 3
» Fig. 113 on
page 105), if the engine is not running. The starter or engine can be damaged if
the starter is activated when the engine is running. ■ Let go of the ignition key as soon as the engine starts otherwise the starter
could be damaged. ■ Avoid high engine revolutions, full throttle and high engine loads as long as the
engine has not yet reached its operating temperature - risk of damaging the en-
gine!
■ 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 the catalytic converter. The battery from an-
other vehicle can be used as a jump-start aid » page 202, Jump-starting.
■ Do not switch the engine off immediately at the end of your journey after the
engine has been operated over a prolonged period at high loads but leave it to
run at an idling speed for about 1
minute. This prevents any possible accumulation
of heat when the engine is switched off. £

The KESSY system makes it possible to switch the ignition on/off and to start/
stop the engine without actively using the key.
A valid key must be in the vehicle to unlock the steering, switch on the steering
and start the vehicle. WARNING
■ Never switch off the ignition while driving, as the electromechanical power
steering and brake booster will no longer operate - risk of accident! ■ Never leave the valid keys in the vehicle, if leaving children unattended in
the vehicle. Otherwise the children could start the engine - risk of accident! Note
■ After pressing the starter button while the steering is locked, the steering is un-
locked, the electrical components are activated (e.g. radio, navigation system etc.)
and the igntion is switched on. ■ If you do not leave the vehicle after locking the steering and wish to unlock the
steering again, press the starter button. At the same time, electrical components
are activated (e.g. radio, navigation system etc.) and the ignition is switched on. ■ The KESSY system is protected against inadvertently switching off the engine
while driving, this means that the engine can only be switched off in an emergen-
cy » page 107.
■ The steering is not unlocked or locked if the starter button is repeatedly press-
ed at short intervals. Ð Unlocking and locking the steering

If the driver's door is opened and the ignition is switched off afterwards, the
steering is only locked after the vehicle is locked.
If the steering is locked and the KESSY system does not manage to unlock the
steering lock the first time (e.g. if the wheels are resting against the curb), the at-
tempt will be repeated twice by the system.
If the steering lock is then not unlocked, the following is shown in the informa-
tion display or information display of the instrument cluster:
Move steering wheel or MOVE STEERING
Slightly move the steering and the system will complete 3
more attempts to un-
lock after 2 seconds. At the same time, the indicator light flashes.
If the steering lock still does not unlock, the following message is displayed in the
information display for 10 seconds:
Steering wheel still locked.
It is necessary to eliminate the possible cause which is preventing the unlocking
and then repeat the attempt to unlock the steering. Ð

Stabilisation Control (ESC) 110
Antilock brake system (ABS) 111
Traction control system (TCS) 111
Electronic differential lock (EDL) 111
WARNING
■ The brake booster only operates when the engine is running. Greater physi-
cal effort for braking is required when the engine is switched off - risk of acci-
dent!
■ Depress the clutch pedal when stopping or braking a vehicle with a petrol
engine and manual transmission in the low rev range. If you fail to do so, the
functionality of the brake booster can be impaired - risk of accident!
■ If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must be
ensured that the air supply to the front wheel brakes is not reduced. Other-
wise, the functionality of the brake system could be impaired - risk of acci-
dent! ■ Please note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating, which can
have a negative effect on the operation of the brake system - risk of accident!
■ Never leave children unattended in the vehicle. The children might, for ex-
ample, release the handbrake or take the vehicle out of gear. The vehicle
might then move off - risk of accident!
■ A lack of fuel can cause irregular engine running or cause the engine to shut
down. The brake assist systems would then be without function - risk of acci-
dent! ■ Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions. The increased safety offered by the brake assist systems
must not tempt you to take greater risks than otherwise - risk of an accident!
■ The normal braking system is still fully functional if there is an ABS fault.
Visit a ŠKODA specialist garage immediately and adjust your style of driving
according to the damage to the ABS as you will not know how great the dam-
age is and the limitation it is placing on the braking efficiency. £
108 Using the system
Page 111 of 235

CAUTION
■ Observe the recommendations on the new brake pads » page 158.
■ Never let the brakes slip with light pressure on the pedal if braking is not neces-
sary. This causes the brakes to overheat and can also result in a longer braking
distance and excessive wear. ■ All four wheels must be fitted with the same tyres approved by the manufactur-
er to ensure the brake assist systems operate correctly. Note
■ If the brakes are applied in full and the control unit for the braking system con-
siders the situation to be dangerous for the following traffic, the brake light
flashes automatically. After the speed was reduced below around 10 km/h or the
vehicle was stopped, the brake light stops flashing and the hazard warning light
system switches on. The hazard warning light system is switched off automatical-
ly after accelerating or driving off again. ■ Before negotiating a steep downhill section, reduce the speed, shift down into
the next lower gear (manual gearbox) or select a lower drive position (automatic
gearbox). As a result, the braking effect of the engine will be used, reducing the
load on the brakes. Any additional braking should be completed intermittently,
not continuously. ■ Changes to the vehicle (e.g. to the engine, brakes, chassis or another combina-
tion of tyres and wheels) can influence the functionality of the brake assist sys-
tems »
page 194 , Accessories, changes and replacement of parts .
■ If a fault occurs in the ABS system, the ESC, ASR and EDL also do not work. A
indicator light » page 23 comes on if a fault occurs in the ABS system. ÐInformation on braking
First read and observe the introductory information and safety warn-
ings on page 108.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driving
style. The brake pads wear more quickly if a lot of journeys are completed in
towns and over short distances or if a very sporty style of driving is adopted. If
operated under severe conditions, the thickness of the brake pads must be
checked by a ŠKODA specialist garage before the next service appointment. ä Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake pads
may be moist or have a coating of ice or layer of salt on them in winter. The
brakes are cleaned and dried by applying the brakes several times.
Corrosion
Corrosion on the brake discs and dirt on the 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. If the brake system is not used much or if there is corrosion on the sur-
face, we recommend cleaning the brake discs by firmly applying the brakes from a
fairly high speed.
Faults in the brake surface
If it is found that the braking distance has suddenly become longer and that the
brake pedal can be depressed further, the brake system may be faulty. Visit a
ŠKODA specialist garage immediately and adjust your style of driving appropriate-
ly as you will not know how great the damage is.
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 20, Brake system .
Brake booster
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running. Ð Handbrake

› Move the lever right down while pressing the lock button.
The handbrake indicator light lights up when the handbrake is applied, provi-
ded the ignition is on.
A warning signal sounds if the vehicle is inadvertently driven off with the hand-
brake applied.
The following is displayed in the information display:
Release parking brake!
The handbrake warning is activated if the vehicle is driven at a speed of more
than 6 km/h for more than 3
seconds. ÐStabilisation Control (ESC)
Fig. 117
ESC system: TCS button
First read and observe the introductory information and safety warn-
ings on page 108.
The ESC is automatically activated after starting the engine. The ESC helps to
maintain control of the vehicle in situations where it is being operated at its dy-
namic limits, such as a sudden change to the direction of travel. The risk of skid-
ding is reduced and your car thus offers greater driving stability depending on the
conditions of the road surface.
The direction which the driver wishes to take is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual
behaviour of the vehicle. In the event of deviations, such as if the car starts to
skid, the ESC automatically brakes the appropriate wheel.
ä The ESC cannot be switched off, the button
» Fig. 117 only deactivates the TCS
system and the indicator light in the instrument cluster lights up.
During an intervention of the system, the indicator light flashes in the instru-
ment cluster.
In the event of an ESC fault, the ESC indicator light illuminates in the instrument
cluster » page 22.
The following systems are integrated into the electronic stabilisation control
(ESC):
› Antilock brake system (ABS),
› Traction control (TCS),
› Electronic differential lock (EDL)
› Active driver-steering recommendation (DSR),
› Brake assist,
› Uphill start assist.
Active driver-steering recommendation (DSR)
This function indicates to the driver in critical situations a steering recommenda-
tion in order to stabilise the vehicle. The active driver-steering recommendation is
activated, for example, on the right and left vehicle side when braking sharply on
different road surfaces.
Hydraulic brake assist
The brake assist system is activated by the very quick operation of the brake ped-
al (e.g. in the event of danger). It increases the braking effect and helps to short-
en the braking distance. To achieve the shortest possible braking distance, the
brake pedal must be applied firmly and held in this position until the vehicle has
come to a complete standstill.
The ABS is activated faster and more effectively with the intervention of the
brake assist system.
The brake assist function is automatically switched off when the brake pedal is
released.
Uphill start assist
The uphill start assist makes it easier to start off on steep hills. The system holds
the brake pressure produced by the activation of the brake pedal for approx.
2 seconds after the brake pedal is released. The driver can therefore move his
foot from the brake pedal to the accelerator pedal and start off on the slope,
without having to actuate the handbrake. The brake pressure drops gradually the
more you operate the accelerator pedal. If the vehicle does not start off within 2
seconds, it starts to roll back. £
