Technical glossary

ABS: the anti-lock braking system prevents
the wheels from locking during heavy or
emergency braking, enabling the vehicle
to remain steerable. When braking, wheel
speed sensors measure the road wheel
speed and should one or more wheels start
to lock the system reduces brake pressure
to that wheel.
MSR: the engine torque control system
recognises when the wheels are subject
to too much slippage and regulates the
power supply by intervening in the engine
management system. This prevents
wheelspin when, for example, changing
down on a smooth or wet road surface.
MSR is a constituent part of the
ASR system.
EDL: the electronic differential lock
continually compares the rpm of the drive
wheels, and if it identifies a difference
between them which could lead to an
individual wheel spinning, for example if the
two wheels are on different types of surface
or accelerating on wet leaves, the system
brakes the wheel affected until uniform
rpm of all drive wheels is restored.
MBA: the mechanical brake assist
system increases brake effort under
emergency braking conditions through
a dual rate servo.
ASR: anti-slip regulation traction control
ensures the Fabia' s stability when pulling
away or accelerating. If the engine power or
torque being transmitted to the drive wheels
is too great, for example on a slippery road
surface, engine torque is automatically
reduced until optimum road holding
returns, thus preventing wheelspin. A light
indicates whether the ASR system is on. It
can be manually switched off.
ESP: electronic stability programme is
designed to stabilise the dynamic handling
response of the vehicle by counteracting
any tendency towards oversteer or
understeer. The ESP constantly compares
the actual movement of the vehicle with
predetermined values and according to
the situation ESP reacts by braking each
wheel individually (according to direction
of slip) and automatically adjusting the
engine' s output.
CAN Bus: the CAN Bus is an electronic
data bus which links the various different
electronic control systems in the car.
It ensures ideal co-ordination between
systems and reduces the amount of
wiring needed in the car.
Fuel cut-out: should one or more of the
airbags inflate after an accident, this system
automatically cuts out the fuel supply,
thus preventing subsequent leakage
of the diesel or petrol.
Trip Computer: the trip computer not
only features an impressive range of data
displays, operating it is simplicity itself.
A multifunction touch key enables you to
call up all relevant data on the easy-to-
read display. Features include external
temperature, time, current fuel
consumption, average fuel consumption,
miles driven and average speed.
DPF: diesel particulate filter is part of the
exhaust system responsible for cleaning the
engine exhaust gases before they enter the
atmosphere. The DPF catches soot particles
emitted in the exhaust gas and it works in
conjunction with the catalytic converter,
which reduces the amount of harmful gases
entering the atmosphere. The DPF must
periodically be emptied of the soot
particles, a process known as regeneration.
This involves elevated exhaust system
temperatures. A driving style is required
during regeneration, where a constant
vehicle speed above 37 mph must be
maintained. This does not always suit
customers who make frequent short
journeys or experience stop/start driving
or drive within inner-city or urban areas.
