CONTAINING RUNNING COSTS
AND POLLUTION
Some suggestions which may help
you to keep the running costs of the
car down and lower the amount of
toxic emissions released into the at-
mosphere are given below.
GENERAL CONSIDERATIONS
Car maintenance
The overall state of the vehicle is an
important factor that has a marked in-
fluence over fuel consumption, driving
comfort and on the life span of your
vehicle. For this reason, care should
be taken to maintain your vehicle by
carrying out the necessary checks and
observing regulations in accordance
with the specifications given in the
Scheduled Maintenance Programme
(see section, idling, air cleaners, tim-
ing).
Tyres
Tyre pressure should be checked at
least once every four weeks: if the
pressure is too low fuel consumption
increases as the resistance to the
rolling movement of the tyre is
greater. In this state, tyre wear is in-
creased and vehicle handling suffers,
which will effect safety.
Unnecessary loads
Do not travel with too much luggage
stowed in the boot. The weight of the
vehicle (especially when driving in the
city) and its trim greatly effects con-
sumption and stability.
Roof rack/ski rack
Remove the roof/ski rack from the
roof when no longer necessary. These
accessories reduce the vehicle's aero-
dynamic penetration, which affects
consumption. Use a trailer, if particu-
larly heavy objects are to be trans-
ported.
Electrical devices
Use electric devices for the neces-
sary time only. The heated rear win-
dow, supplementary lights, windscreen
wipers, heating system blower require
large amounts of electricity; this means
an increase in the request for power
and consequently an increase in fuel
consumption (up to +25% when dri-
ving in built-up areas).
Climate control system
The climate control unit is an addi-
tional load that greatly affects the en-
gine leading to higher consumption (on
average +20%). When the tempera-
ture outside allows it, use the air
vents.
Spoilers
The use of optional extras which are
not certified for specific use on the car
may reduce the aerodynamic pene-
tration of the car and increase con-
sumption.
