Heating and air conditioning system
Heating and 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 72 or for Climatronic »
page 74.
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 heating and air conditioning systems work 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.

WARNING
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. ÐAir conditioning system (manual air conditioning
system) Introductory information
The cooling system only operates if the button AC 2
» Fig. 76 on page
70 is
pressed, and the following conditions are met:
› engine running;
› outside temperature above approx. +2 °C;
› blower switch switched on (positions 1 to 4).
Under certain circumstances, air at a temperature of about 5 °C can flow out of
the vents when the cooling system is switched on. Lengthy and uneven distribu-
tion of the air flow out of the vents and large differences in temperature, for ex-
ample when getting out of the vehicle, can result in chills in sensitive persons. Note
We recommend that you have the air conditioning system cleaned by a ŠKODA
specialist garage once every year. Ð Using the system

Climatronic (automatic air conditioning system)
Introductory information
The Climatronic maintains fully automatically a convenience temperature. This is
achieved by automatically varying the temperature of the air flow, the blower
stages and air distribution. The system also takes sunlight into account, which
eliminates the need to alter the settings manually. The automatic
mode » page 74 ensures maximum well-being of the occupants at all times of
the year.
Description of Climatronic system
The cooling system only operates if the following conditions are met:
› engine running;
› outside temperature above approx. +2 °C;
› AC 18
» Fig. 77
on page 73 switched on.
The AC compressor is switched off at a high coolant temperature in order to pro-
vide cooling at a high load of the engine.
Recommended setting for all periods of the year.

The interior temperature can be set between +18 °C and +29 ℃. The interior tem-
perature is regulated automatically within this range. If you select the tempera-
ture below +18 ℃, “LO” appears in the display. If you select the temperature high-
er than +29 ℃, “HI” appears in the display. In both limit positions the Climatronic
operates at maximum cooling or heating capacity, respectively. The temperature
is not controlled in this case.
Lengthy and uneven distribution of the air flow out of the vents (especially
around the feet) and large differences in temperature, for example, when getting
out of the vehicle, can cause susceptible individuals to catch a cold. Ð17

74 Using the system

For the sake of the environment
Do not warm up the engine while the vehicle is stationary. If possible, start your
journey as soon as the engine has started. Through this the engine reaches its
operating temperature more rapidly and the pollutant emissions are lower. Note
■ The engine can only be started with a genuine ŠKODA key with the matching
code. ■ The engine running noises may louder at first be louder for a short time after
starting the cold engine. This is quite normal and is not an operating problem. ■ After switching off the ignition, the radiator fan can intermittently continue to
operate for approx. 10
minutes.
■ If the engine does not start up after a second attempt, the fuse for the fuel
pump may have a fault. Check the fuse and replace, if necessary » page 166,
Fuses or seek assistance from a

ŠKODA specialist garage.
■ We recommend locking the steering wheel whenever leaving the vehicle. This
acts as a deterrent against the attempted theft of your car. ÐAdjusting the steering wheel position
Fig. 78
Adjustable steering wheel: Lever below the steering column/safe
distance to the steering wheel
First read and observe the introductory information and safety warn-
ings on page 76.
The height and forward/back position of the steering wheel can be adjusted.
› First of all adjust the driver's seat
» page 47, Front seats .
› Pull the lever below the steering wheel down
» Fig. 78 - .
ä ›
Adjust the steering wheel to the desired position (with regard to the height and
forward/back position).
› Push the lever upwards to the stop. Ð Electrohydraulic power steering
First read and observe the introductory information and safety warn-
ings on page 76.
The power steering enables you to steer the vehicle with less physical force.
It is still possible to fully steer the vehicle if the power steering fails or if the en-
gine is not running (vehicle being towed in). However, greater physical effort is
required to turn the steering wheel.
If there is a fault in the power steering, the warning light then lights up in the in-
strument cluster  » page 17, Warning lights . Ð Electronic immobiliser
First read and observe the introductory information and safety warn-
ings on page 76.
An electronic chip is integrated in the head of the key. The immobiliser is deacti-
vated with the aid of this chip when the key is inserted in the ignition lock. The
electronic immobiliser is automatically activated when the ignition key is with-
drawn from the lock.
The engine will not start if a non-authorized ignition key is used.
The following is displayed in the information display: Immobilizer active. Ð

Starting-off and Driving

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. CAUTION
■ Observe the recommendations on the new brake pads » page 119.
■ 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.
■ If a fault occurs in the ABS system, the ESC, ASR and EDL also do not work. A
warning light  » page 21 comes on if a fault occurs in the ABS system. Ð Information for braking
First read and observe the introductory information and safety warn-
ings on page 78.
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.
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. £

Starting-off and Driving

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 18, 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. ÐHandbrake
Fig. 80
Centre console: Handbrake
First read and observe the introductory information and safety warn-
ings on page 78.
Apply
› Pull the handbrake lever firmly upwards.
Loosening
› Pull the handbrake lever up slightly and
at the same time push in the locking
button » Fig. 80 .
› Move the lever right down while pressing the lock button.
The handbrake warning light  lights up when the handbrake is applied, provided
the ignition is on. Ð
ä Stabilisation control (ESC)
First read and observe the introductory information and safety warn-
ings on page 78.
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.
During an intervention of the system, the warning light  flashes in the instru-
ment cluster.
In the event of an ESC fault, the ESC warning light illuminates in the instrument
cluster  » page 20.
The following systems are integrated into the electronic stabilisation control
(ESC):
› Antilock brake system (ABS),
› Traction control (TCS),
› Electronic Differential Lock (EDL)
› Brake assist,
› Uphill start assist.
It is not possible to deactivate ESC. You can only use the button  » Fig. 81 on
page 81 to switch off ASR. The TCS warning light  lights up in the instrument
cluster when the TCS is switched off.
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. £
