When dev eloping and manufac turing your

Dr ive in an energy a nd environment-
consc ious w ay
zHigh fuel consumption, noise lev els and
exhaust em issions are often caused by a
driving s tyle that is not energy and
environment-conscious.
zYou should therefore drive with energy in
mind: "more kilometre s/ miles with le ss
fuel".
Reduce the noise level and exhaust
emissions b y adopting an environment-
consc ious driving s tyle. This is ex treme ly
worthwhile and im proves the quality of
life.
Fuel consum ption d epend s to a great
extent on your own personal d riv ing
style. The following hints are intended to
help you consume fuel at a rate that is as
clos e as poss ible to the spe cified le vels –

C heck y our v ehicle’ s fuel consumption
e very time you refuel. This facilitates
e arly de tection of any irre gula ritie s
causing increased fuel consumption. Warm ing up
zFull throttle and w arming up at idle
speed increase w ear, fuel consumption,
ex haust em issions, the amount of
pollutant in the exhaust and the am ount
of noise.
zDriv e off as s oon as poss ible a fte r

Uniform speed
zHectic driving s ignificantly increas e s fuel
consumption, the ex haust emissions, the
proportion of pollutant in the exhaust
g a s es a n d t h e no i s e l eve l .
zDo not accele rate a nd brake
unnecessarily . Drive at uniform speed.
Avoid frequent starting-off and
stopping, e.g. at traffic lights, in short
distance traffic and in que ue s of tra ffic,
by m eans of clev er planning. S ele ct
