Instruments and Indicator/Warning Lights
40
Note
If the battery has been disconnected and reconnected, the warning light  comes on after switching on the ignition. The warning light must go out
after driving a short distance.
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), and the Antilock Brake System
(ABS).
The warning light comes on when driving when a control cycle is acti-
vated.
The warning lig ht will come on an d 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.
If the warning light
 comes on immediately after starting the engine, the
ESP system can be switched off for technical reasons. In this case, the
ESP system can be switched on again by switching the ignition on and off.
If the warning light goes out, the ESP system is fully functional again.
Further information on the ESP ⇒page 213, “Electronic stability
programme (ESP)*”.
Electronic Differential Lock (EDL)*
The EDL is a part of the ESP. A fault in the EDL is indicated by the ESP
warning light in the instrument cluster. Have the vehicle inspected without delay by a Škoda dealer. Further information on the EDL
⇒page 214,
“Electronic Differential Lock (EDL)*”.
Note
If the battery has been disconnected and reconnected, the warning light  comes on after switching on the ignition. The warning light must go out
after driving a short distance.
Dynamo 
The warning light  comes on after the ignition has been switched on. It
should go out after the engine has started.
If the warning light does not go out after the engine has started, or comes
on when driving, drive to the nearest specialist garage. The vehicle battery
will be discharged in this case so switch off all non-essential electrical
components.
Caution
If the warning light  comes on when driving and in addition the warning
light  (cooling system fault) also comes on in display, you must then
stop the car immediately and switch the engine off - risk of engine
damage!
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.

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),
•Driver-steering recommendation,
•Antilock brake system (ABS),
•Brake Assist,
•Uphill-Start off-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.

Intelligent Technology
214
The ESP operates in combination with the ABS ⇒page 218, “Antilock
brake system (ABS)”. If there is a fault in the ABS system, the ESP also
does not operate.
The ESP warning light ⇒page 40 lights up in the instrument cluster when
there is a fault on the ESP.
Switching off
You can switch the ESP off and on again as you wish, by pressing the
button ⇒page 213, fig. 180 . The ESP warning light ⇒page 40 lights up in
the instrument cluster when the ESP is switched off.
The ESP should normally always be switched on. It may be good practice
in certain exceptional cases, such as when you wish to have wheel slip,
to switch off the system.
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 ESP again.
WARNING
It is also not possible for the E SP to overcome the physical limits
of the vehicle. Even if a vehicle fitted with ESP you should still
always adapt your style of driving to the condition of the road
surface and the traffic situation. This particularly applies when
driving on slippery and wet roads. 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 ESP. 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 ESP
⇒ page 270, “Accessories, changes and replacement of parts”.
Electronic Differential Lock (EDL)*
The electronic differential lock prevents an individual
wheel from slipping.
Models fitted with ESP are equipped with electronic differential lock (EDL).
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
