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 Roomster'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.
The CAN Bus system (described above)
requires a new generation of towing
electrical adapters and the Roomster
utilises a 13-pin European System.
This can then be easily converted to a
single 7 pin socket for users with a trailer.
For users with Caravans a number of
options are available depending on the
need for a fixed/detachable Towbar, ability
to use reversing sensors and age of
Caravan. A number of different 13 Pin to
Twin 7 pin adapters are available - please
ask your retailer for more information.
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 multi-function 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
HBA: Hydraulic Brake Assistant - speeds
up the brake effect in case of hard braking.
