Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
The warning light comes on for a few seconds after the ignition has been
switched on or when starting the engine. The warning light goes out after
an automatic check sequence has been completed.
A fault in the ABS
If the ABS warning light
 does not go out within a few seconds after
switching on the ignition or does not light up at all or lights up while driving,
the system is not functioning properly and the vehicle will be braked
without the aid of ABS. The vehicle will only be braked by the normal brake
system. Visit a specialist garage as quickly as possible and adjust your
style of driving in the meantime since you will not know how great the
damage is.
Three additional warning tones will sound if there is a major fault in the
ABS.
Further information about ABS ⇒page 218, “Antilock brake system
(ABS)”.
A fault in the entire brake system
If the ABS warning light
 comes on together with the brake system
warning light  (handbrake must be released), there is a fault not only in
the ABS but also in another part of the brake system ⇒.
WARNING
•If the brake system warning light  comes on together with the
ABS warning light  stop the vehicle immediately and check the
brake fluid level in the reservoir ⇒page 256, “Brake fluid”. If the
fluid level has dropped below th e MIN marking, do not drive any
further - risk of accident! Contact a Škoda dealer to obtain profes-
sional assistance.
•Pay attention to the following instructions ⇒page 248, “Working
in the engine compartment” before checking the brake fluid level
and opening the bonnet.
•If the brake fluid is at the correct level, the ABS control function
has failed. The rear wheels may then block very rapidly when
braking. In certain circumstances, this can result in the rear end of
the car breaking away - risk of skidding! Drive carefully to the
nearest specilaist garage and have the fault rectified.
Traction control system (TCS) 
The warning light  comes on for a few seconds when the ignition is
switched on.
The warning light comes on when driving when a control cycle is acti-
vated.
The warning light will come on and remains on if the TCS is switched off
or if there is a fault in the system.
The fact that the TCS system operates together with the ABS means that
the TCS warning light will also come on if the ABS system is not operating
properly.
If the warning light
 comes on immediately after starting the engine, the
TCS system can be switched off for technical reasons. In this case, the
TCS system can be switched on again by switching the ignition on and off.
If the warning light goes out, the TCS system is fully functional again.

Heating and air conditioning system
128
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 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:
•The fuse on the air conditioning system has blown. Check the fuse,
replace it if necessary ⇒page 288.
•The cooling system has switched off automatically for a short time
because the coolant temperature of the engine is too hot ⇒page 14.
If you are not able to rectify the operational problem yourself, or if the
cooling capacity decreases, switch the cooling system off. Contact a
specialist garage.
Climatronic* (automatic air conditioning)
Description
The Climatronic system is a combination of an automatic
heating, fresh air and cooling system which provides
optimal comfort for the occupants of the car.
The Climatronic maintains a constant temperature fully automatically,
once it has been set. This is achieved by automatically varying the
temperature of the outflowing air, the blower stages and the air distribu-
tion. The system also takes into account bright sunlight which eliminates
the need to alter the settings manually. The automatic mode ⇒ page 130
ensures maximum wellbeing of the occupants at all times of the year.
Description of Climatronic system
The cooling operates only if the following conditions are met:
•engine running,
•outside temperature above +2 °C,
•the button is not pressed.
If the cooling system is switched on, the temperature and air humidity
drops in the vehicle. The wellbeing 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.
The heating effect is dependent upon the coolant temperature, thus full
heat output only occurs when the engine has reached its operating
temperature.
It is possible to briefly activate recirculated air mode in order to enhance
the cooling effect ⇒.ECON

Starting-off and Driving141
Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistanceTechnical Data
Petrol engines
These engines are fitted with a starter system which selects the correct
fuel/air mixture for every external air temperature.
•Do not operate 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 electrical fuel pump is defect if the
engine still does not start. Check the fuse and replace it if necessary
⇒ page 288.
•Contact the nearest specialist garage to obtain professional assist-
ance.
It may be necessary, if the engine is very hot, to slightly depress the
accelerator after the engine has started.
Diesel engines
Glow 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 temperature.
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 ve hicle 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 288.
•Contact the nearest specialist garage to obtain professional assist-
ance.
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 the engine off
– The engine can be switched off by turning the ignition key from position ⇒page 139, fig. 129 into position .
WARNING
•Never switch off the engine before the vehicle is stationary - risk
of accident!
•The brake booster only operates when the engine is running.
Greater physical effort for braking is required when engine is
switched off. Because if you do not stop as normal, this can cause
an accident and severe injuries.
