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 86
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 13

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.
› Set the desired temperature, we recommend 22 °C.

■ We recommend that you have the Climatronic system cleaned by a
ŠKODA spe-
cialist garage once every year. ■ On vehicles equipped with a factory-fitted radio or radio navigation system, the
Climatronic information is also shown on their displays. This function can be

Introduction
This chapter contains information on the following subjects:
Direct switching on/off 88
System settings 89
Radio remote control 89
Changing the battery of the radio remote control 90
Auxiliary heating (parking heating)
The auxiliary heater (parking heater) functions in connection with the air-condi-
tioning 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. £

Heating and air conditioning system

De-icing windows and exterior mirrors
First read and observe the introductory information and safety warn-
ings on page 148.
Use a plastic ice scraper for removing snow and ice from the windows and mir-
rors. The ice scraper should not be moved forward and backward but in one direc-
tion to avoid any damage to the surface of the glass.
Clean the windows from the inside on a regular basis.
Dry the glass surfaces with a clean chamois leather or a cloth intended for this
purpose.
When drying the windows after washing the vehicle, do not use window leathers
that have been used to polish the bodywork. Residues of preservatives in the
window leather can dirty the window and reduce visibility. CAUTION
■ Never remove snow or ice from glass parts using warm or hot water - risk of for-
mation of cracks in the glass!
■ When removing snow or ice from windows and mirror lenses ensure that the
paintwork of the vehicle is not to damage.
■ Snow or ice that is contaminated with coarse dirt such as fine gravel, sand, and
salt must not be removed from the window glass and mirrors - risk of damage to
the surface of the windows and mirrors. ÐRadio reception and aerial
First read and observe the introductory information and safety warn-
ings on page 148.
Car parks, tunnels, tall buildings or mountains can disrupt the radio signal even
causing it to fail completely.
With factory-fitted radios and navigation systems, the aerial for the radio recep-
tion can be installed at different locations in the vehicle:
› on the inside of the rear window along with the rear window heater;
› on the inside of the rear side windows;
› on the inside of the windscreen;
› on the roof. Ð
ä
ä Headlight lenses
First read and observe the introductory information and safety warn-
ings on page 148.
Use soap and clean water to clean the plastic headlight lenses.
CAUTION
■ Never wipe the headlights dry and do not use any sharp objects to clean the
plastic lenses, this may damage the protective paintwork and consequently cause
the formation of cracks on the headlight lenses.
■ Do not use any aggressive cleaning or chemical solvent products to clean the
headlights - risk of damaging the headlight lenses. Ð Rubber seals
First read and observe the introductory information and safety warn-
ings on page 148.
The rubber seals on doors, the sliding roof and other windows remain smoother
and last longer if the seals are treated regularly with a suitable rubber care prod-
uct. This helps to prevent leakages and premature wear of the seals. Rubber
seals which are well cared for also do not stick together in cold winter weather.
Ð Door lock cylinders
First read and observe the introductory information and safety warn-
ings on page 148.
Specific products must be used for de-icing door lock cylinders.
Note
■ When washing your vehicle, ensure as little water as possible gets into the lock-
ing cylinders. ■ We recommend that suitable materials from ŠKODA Original Accessories are
used for maintaining the door lock cylinders. Ð

Taking care of and cleaning the vehicle

Changing engine oil
First read and observe the introductory information and safety warn-
ings on page 158.
The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator
» page 10, Service Interval Display.CAUTION
Additives must not be added to the engine oil - risk of causing considerable dam-
age to parts of the engine! Damage, which results from such product, are exclu-
ded from the warranty. Note
If your skin has come into contact with oil, it must be washed thoroughly. ÐCoolant
First read and observe the introductory information and safety warn-
ings on page 158.
The cooling system is filled with a coolant in the factory.
The coolant consists of water with a concentration of coolant additive of 40 %.
This mixture provides antifreeze protection down to -25
°C and 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.
The concentration of coolant must therefore not be reduced by adding water dur-
ing the summer months or in countries with a warm climate. The concentration of
coolant additive in the coolant must be at least 40 %. 40 %.
If a higher concentration of antifreeze is required for climatic reasons, the amount
of coolant additive can only be increased 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 are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries the concentration of coolant additive should be at least 50 %.
When refilling, we only recommend you use the same antifreeze written on the
antifreeze expansion tank » Fig. 135 on page 163.

■ Other coolant additives that do not comply with the correct specifications can
above all significantly reduce the anticorrosion effect.
■ Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage! Note
On vehicles that are fitted with an auxiliary heater (auxiliary heating and ventila-
tion), the coolant capacity is approx. 1 l larger. Ð
162 General Maintenance

Automatic load deactivation
First read and observe the introductory information and safety warn-
ings on page 165.
An intelligent vehicle power management system automatically takes various
measures at high loads on the vehicle battery to prevent discharging of the bat-
tery: This manifests itself by the following:
› The idling speed is raised to allow the generator to deliver more electricity to
the electrical system.
› Where appropriate large consumers of power, e.g. seat heaters, rear window
heaters, voltage supply to the 12V power socket, have their power limited or in
case of emergency shut off completely. Note
Despite such intervention by the vehicle electric system management, the vehicle
battery may be drained. For example, when the ignition is switched on a long time
with the engine turned off or the side or parking lights are turned on during lon-
ger parking. Driving comfort is not put at risk by any shutting off of consumers.
Often the driver is not aware of it having taken place. Ðä
