Control system for exhaust gases 
The warning light  comes on after the ignition has been switched on.
If the warning light does not go out after starting the engine or it lights up
or flashes when driving, a fault exists in an exhaust relevant component.
The engine management system selects an emergency programme
which enables you to drive to the nearest Škoda dealer while adopting a
gentle style of driving.
The following text will be displayed in the information display*: EMISSIONS WORKSHOP!
Electronic Stability Programme (ESP)* 
The warning light  comes on for a few seconds when the ignition is
switched on.
Components of the ESP system also include the Traction Control System
(TCS), Electronic Differential Lock (EDL), the Antilock Brake System ABS
and the braking assistant
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 ESP is switched off
or if there is a fault in the system.
The fact that the ESP system operates together with the ABS means that
the ESP warning light will also come on if the ABS system is not operating
properly.
Further information on the ESP
⇒page 175, “Electronic stability
programme (ESP)*”.

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
The system is not functioning properly if the warning light
 does not go
out within a few seconds after switching on the ignition, does not light up
at all or lights up while driving. The vehicle will only be braked by the
normal brake system without the effect of the ABS function. Visit a Škoda
dealer as quickly as possible and adjust your style of driving in the mean-
time 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 179, “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 ⇒ .
The following text will be displayed in the information display*: STOP BRAKE FAULT SERVICE MANUAL
Electronic Differential Lock (EDL)
The EDL is a part of the ABS. A fault in the EDL is indicated by the ABS
warning light
 in the instrument cluster. Have the vehicle inspected
without delay by a Škoda dealer. Further information on the
EDL ⇒page 177.
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 217, “Brake fluid” . If the
brake fluid level has dropped below the MIN marking, do not drive
any further - risk of accident! Contact a Škoda dealer to obtain
professional assistance.
•Pay attention to the following instructions ⇒page 209,
“Working in the engine compartment” before checking the brake
fluid level and opening the bonnet.
Electronic immobiliser 
Data is compared between the ignition key and the control unit when
switching on the ignition. The indicator light  will light up for a few
seconds when ignition key authorisation is confirmed.
The warning light will start flashing continuously if a non-authorised igni-
tion key (for example the wrong ignition key) has been used. The engine
cannot be started ⇒page 40.
It is only possible to start the engine of the vehicle with a Genuine Škoda
key with the matching code.
Brake system 
The warning light  flashes or comes on if the brake fluid level is too low,
if there is a fault in the ABS or if the handbrake is applied.
If the warning light
 flashes (handbrake is not applied), stop and check
the brake fluid level ⇒.

Electronic stability programme (ESP)*
General
General
The ESP aids you maintain control of your vehicle in situations in border-
line driving situations such as when negotiating a curve too fast. The risk
of skidding is reduced and your car thus offers greater driving stability
depending on the conditions of the road surface. This occurs at all speeds.
The following systems are integrated into the electronic stability
programme:
•Electronic Differential Lock (EDL)
•Traction control system (TCS)
•Antilock brake system ABS
•Brake Assist
Operating principle
The ESP switches on automatically when the engine is started and then
conducts a self-test. The ESP control unit processes data from the indi-
vidual systems. It also processes additional measurement data which are
supplied by highly sensitive sensors: the rotational velocity of the vehicle
about its vertical axis, the lateral acceleration of the vehicle, the braking
pressure and the steering angle.
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. If differences exist, such as the
car beginning to skid, the ESP will automatically brake the appropriate
wheel.
The car is stabilised again by the forces which take effect when the wheel
is braked. Intervention into the brake system takes place primarily on the
outer front wheel of a vehicle which tends to oversteer (tendency for the
rear of the vehicle to break away) while occurs this is on the inner rear
wheel of a vehicle which tends to understeer (tendency to shift out of the
curve). This braking control cycle is accompanied by noises.
The ESP operates in combination with the ABS ⇒page 179, “Antilock
brake system (ABS)”. If there is a fault in the ABS system, the ESP also
does not operate.

mitted to the road surface is automatically adapted by reducing the engine
speed. This occurs at all speeds.
The TCS operates in combination with the ABS
⇒page 179, “Antilock
brake system (ABS)”. The TCS will not function if a fault exists in the ABS
system.
The TCS warning light ⇒page 34 lights up in the instrument cluster when
there is a fault on the TCS.
Switching off
You can switch the TCS off and on again as you wish by pressing the
button ⇒page 176, fig. 151 . The TCS warning light ⇒page 34 lights up
in the instrument cluster when the TCS is switched off.
The TCS should normally always be switched on. It may be good practice
to switch the system off only in particular exceptional situations if you
desire wheel slip.
Examples:
•when driving with snow chains
•when driving in deep snow or on a loose surface
•when it is necessary to rock a car free when it has become stuck
then you should switch on the TCS again.
The EDL ⇒page 177, “Electronic Differential Lock (EDL)” is a part of the
TCS. THE EDL operates independently of the TCS (also when the TCS
has been switched off using the TCS button).
WARNING
You should always adjust your style of driving to the conditions of
the road surface and the traffic situation. The increased safety
offered must not tempt you to take greater risks than otherwise -
risk of an accident!
Note
•All four wheels must be fitted with the same tyres in order to achieve
problem-free operation of the TCS. Differing rolling circumferences of the
tyres can lead to an undesirable reduction in the engine output.
•Changes to vehicle (e.g. on engine, on the brakes, on chassis or other
assignment of tyres and wheels) can influence the function of the TCS
⇒ page 233, “Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)
The electronic differential lock prevents an individual
wheel from slipping.
General
The EDL makes it much easier, and sometimes at all possible, to start off,
accelerate and climb a steep hill when the conditions of the road surface
are unfavourable.
Operating principle
The EDL is activated automatically, that is without any action on the part
of the driver. It monitors the speeds of the driven wheels with the aid of the
ABS sensors. Should only one drive wheel begin spinning on a slippery
surface there will be an appreciable difference in the speed of the driven
wheels. The EDL function brakes the slipping wheel and the differential
transmits a greater driving force to the other driven wheel. This control
process is also accompanied by noises.
Overheating of the brakes
The EDL switches off automatically if unusually severe stresses exist in
order to avoid excessive heat generation in the disc brake on the wheel
which is being braked. The vehicle can continue to be driven and has the
same characteristics as a vehicle not fitted with EDL.
