64CONTROLS AND EQUIPMENT3 - Electronic stabilityprogram* ESPModels fitted with anti-lock brake system
(ABS) can be equipped additionally with an
electronic stability program (ESP).
The ESP makes it possible to enhance
control over the vehicle in situations in
which the vehicle is operating at the dyna-
mic limits, such as driving too fast into a
curve. The ESP is an extension of the ABS/
EBC//TCS/EDL function and reduces the
risk of skidding in all road conditions. The
system operates over the entire speed of
the vehicle in conjunction with the ABS. If
a fault develops in the ABS system, the ESP
then also does not operate.
The ESP is switched on automatically each
time the engine is started. It can be swit-
ched off and on, as desired, together with
the TCS system, by pressing the pushbut-
ton.
If the system is switched off, the ESP warn-
ing light comes on - see page 60.
In exceptional cases where wheel slip is
desired, it is beneficial to switch off the ESP
system. For example:
- when driving with snow chains
- when starting off in deep snow or on a
loose surface
- when rocking the car free if it has got stuck.
The system should be switched on again
after this.
Note
The same tyres must be fitted to all four
wheels if the ESP system is to operate
properly. Differing rolling circumferences of
the tyres can result in an undesirable re-
duction in engine output.
Repairs on the vehicle (e.g. on engine,
braking system, chassis or another combi-
nation of wheels and tyres) can influence
the function of the ESP.
Operating principle of ESP
The ABS, EBC, EDL, TCS systems are in-
tegrated in the electronic stability program.
In addition to the data available from these
functions, the ESP control unit is also sup-
plied with signals which are transmitted by
highly sensitive sensors. What is measu-
red is the spinning rotary motion about the
vertical axis of the vehicle, the lateral ac-
celeration of the vehicle, the brake pressu-
re and the steering lock.
Note
The direction selected by the driver is de-
termined with the aid of the movement of
the steering and the vehicle speed and
constantly compared with the actual behav-
iour of the vehicle. If variations exist, such
as the vehicle beginning to slide, the ESP
automatically brakes the wheel in question
and reduces engine speed.
The vehicle is again stabilised as a result
of the forces acting on the wheel during the
braking operation. If the vehicle is overs-
teering (tending to break away at the rear),
it is primarily the outside front wheel which
is braked, whereas, if the vehicle is under-
steering (tending to slide out of the curve),
the rear inner wheel is then braked.
Warning
The ESP system is also not able to
overcome the physical limits of the
vehicle. You should remember this,
particularly when driving on slippery
and wet road surfaces.
Your style of driving should always
be adapted to the condition of the
road and the traffic situation. The
enhanced safety offered by the ESP
must not tempt you to take any risks
which compromise your safety.

122DRIVING TIPSAnti-lock brake system (ABS)*The ABS plays a major part in increasing
the active safety of the vehicle.
The big advantage when compared with a
conventional brake system is that even
during a full brake application on a slippery
road surface the best possible steerability
is retained for the road condition because
the wheels do not lock.
However, one must not expect the ABS
system to shorten the braking distance
under all conditions.
How the ABS system works
An automatic test procedure is carried out
once the car has reached a speed of about
20 km/h. A pump noise may be audible for
about 1 second during this check.
When the turning speed of a wheel reaches
a level which is too low for the vehicle speed
and it tends to lock, the brake pressure to
this wheel is reduced. The brake pressure
is controlled individually for each wheel.
This ensures that the braking action is even
and that driving stability is retained to the
maximum possible extent.This control process makes itself felt by
a pulsing movement of the brake pedal
and is accompanied by noises. This is done
deliberately as a warning to the driver that a
wheel or wheels are in the locking range. The
brake pedal should remain depressed to en-
able the ABS to offer ideal control within this
range - on no account pump the brake pedal!
Warning
The ABS system can also not over-
come the physical limits. This has to
be born in mind, particularly on slip-
pery or wet roads. When the ABS is
operating in the control range, your
speed should immediately be adap-
ter to road and traffic conditions.
The increased amount of safety avail-
able should not tempt you into tak-
ing risks.
If a fault occurs in the ABS system, this is
indicated by a warning lamp - see page 60. Warning
If a fault exists, only the normal brake
system is operational. You should
drive to a Škoda Dealer as soon as
possible. Adapt your speed and driv-
ing style to the changed circum-
stances as the extent of the damage
to the ABS system is not known.
Electronic differential lock (EDL)*Cars fitted with the anti-lock brake system
(ABS)* can be equipped in addition with an
electronic differential lock.
The EDL system makes it much easier or,
in deed, at all possible to move off, accel-
erate and drive uphill even on unfavourable
road surfaces.
The EDL operates automatically - in other
words without any action on the part of the
driver.
It monitors the speed of the driven wheels
using the sensors of the ABS system.
If the road surface is slippery on one side,
a difference in speed exists between the
driven wheels. It is then necessary to pro-
duce more throttle, for example, when mov-
ing off on a hill, on a slippery road surface
etc. The EDL function compensates for the
difference in speed by braking the wheel
which is slipping and transmits the power
through the differential to the other driven
wheel.
This control process makes itself notice-
able by characteristic noises.

138GENERAL MAINTENANCE
LongLife Service*The LongLife Service ensures that your
vehicle is always in proper roadworthy con-
dition while requiring only minimal effort on
your part.
The LongLife Service is determined on the
basis of:
- Oil level and pressure sensor - see page 59
- Brake wear indicator - see page 58
- Engine oils complying with the standard VW 503 00 (petrol engines), VW 506 00
(diesel engines, except PDi engines)
and VW 506 01 (diesel engines) - see
page 138
- Variable service interval display - see page 49
- Battery with so-called „magic eye“ - see page 148.
Further information - refer to Service Sche-
dule. More detailed information is also
available from your Škoda Dealer.
SpecificationThe engine is factory-filled with a brand-
name multigrade oil which can be used as
an all-seasons oil - except in extremely cold
climatic zones. Oils may also be intermixed
when topping up (does not apply to mod-
els with LongLife Service*).
We recommend using oils from the selec-
tion of original oils available at Škoda.
Note
Engine oils naturally also undergo continu-
ous further development. That is why the
information contained in this Owner’s
Manual reflects the technical status at the
time of publication.Engine oil
Škoda Dealers are kept up-to-date by the
factory regarding any changes. It is there-
fore good practice to have the oil change
carried out at a Škoda Dealer.
