CONTROLS AND EQUIPMENT
Electronic differential lock (EDL)*The EDL system operates in combination
with the ABS. A failure of the EDL system
is indicated by the ABS warning light co-
ming on. You should then contact a Škoda
Dealer without delay.
Models fitted with ESP are equipped with
electronic differential lock (EDL).
If a major fault is present in the ABS sy-
stem, an audible warning signal also
sounds (3 peeps). Further information on
the ABS and EDL systems is given on
pages 122 and 124.Electronic immobiliserWhen the ignition is switched on, a data
harmonization is performed between key
and control unit. If the data exchanged are
correct, this is confirmed by the warning li-
ght coming on for a few seconds.
If an unauthorized car key (e.g. forged key)
has been used, the warning light changes
to a continuous flashing light. It is then no
longer possible to start the car - see page
7.
Brake fluid levelThe warning light comes on for a few se-
conds after switching on the ignition.Warning
If the warning light comes on when
the ignition is switched on or when
driving, there is a fault in the brake
system. Contact the nearest Škoda
Dealer without delay and have the
brake system inspected.
An audible warning signal sounds
(3 peeps).
You can drive on carefully to the near-
est Škoda Dealer but allow for higher
pedal pressures, longer braking dis-
tances and greater idle travel of the
brake pedal.
The warning light also comes on when the
handbrake is applied.
Charge indicatorThe warning light comes on when the igni-
tion is switched on. It should go out when
the engine is started.
If the warning light comes on when driving
or does not go out after the engine has
started, stop the car and switch off the
engine. Check the ribbed belt.
If it is loose or broken, do not drive any
further . The belt has to be tensioned or
replaced.
If the ribbed belt is in proper order and the
warning light nevertheless comes on, it is
possible to drive on to the nearest Škoda
Dealer. In this case, the battery will not be
charged; switch off all unnecessary elec-
trical components in the vehicle.
An audible warning signal sounds (single
peep signal).Seat belt warning system*This warning light comes on to request the
driver to fasten the seat belt.
If the driver’s belt is not fastened, an audi-
ble warning signal sounds for 6 seconds.

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.
