When dev eloping and manufac turing your
vehicle, Opel used environment-friendly
and prima rily recy clable materials . The
production methods used to ma ke your
vehicle are likewise environmenta lly-
compatible .
Recycling of production wastes keeps the
circulation of material clos ed. Re duction of
energy a nd water requirements a lso help s
to conserve natural resources.

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 –
s ee page 1 77 .
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
st a r t i n g .
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
roa ds with good traffic flow.
I dling
zThe eng ine also consumes fuel when
idling .
zIf yo u h ave to wait f o r mo r e th an
1 minute , it is worthwhile s witching off
the e ng ine . F ive minute s of idling
corre s ponds to ap prox . 1 kilome tre
(0.6 m ile s) of driv ing .

11 3Dr i vi ng and o pe r ati on
O ve rrun
zThe fuel s upply is automatically shut off
during ov errun, e. g. whe n the ve hicle is
being drive n down long gradie nts or
whe n braking – s ee page 1 11 .
zTo enable the ove rrun cut-off to take
effect a nd sav e fue l, during overrun do
not ac cele ra te and do not declutch.
Corr ect ge ar sel ec tion
zHigh revs increas e engine w ear and fue l
consumption.
zDo not race your engine. Avoid d riv ing at
high e ngine s pee ds .
Dr i v in g w i t h a n ey e o n t h e t a ch om et e r
save s fuel. I f pos sib le , drive a t low rev s in
each ge ar and a t a consta nt s pe ed.
Driv e in top g ear as m uch a s p os s ible,
shift up as s oon as pos s ib le and do not
shift down until the e ngine is no longe r
running truly . High speed
zT h e f a s t er t h e sp ee d, t h e h i g h e r t he f u el
consump tion and the noise level. Driv ing
at full throttle use s up a gre at de al of fue l
and g enerates excessive noise and high
e miss ion leve ls.
zSlightly relea sing the acce le rator ped al
res ults in distinct fuel s avings with no
major los s of spe ed.
Drive at no more tha n around thre e
quarters of max imum spe ed and you will
use up to 50% less fue l, without losing a
gre at de al of time.
Ty re pre ssure
zInade quate ty re p re s sure, leading to
higher road res istance , cos ts m one y in
two wa ys: more fue l and increa se d tyre

zRe gular checks (e very 14 d ays ) pay off.
Ele ctri cal lo a ds
zThe power cons um ption of e lectrical
equip ment increa ses fuel consumption.
zSw itch off ad ditional c ons umers (e. g.
air conditioning, heate d re ar window)
when they are no longer required. Re pai r and m ainte nance
zImprope r repairs or adjus tm ent and
maintenance work can increase fuel
consumption. Do not carry out w ork on
the eng ine yourself.
You ma y infring e environmental la ws out
of ignorance by not d isposing of
materials prope rly.
Appropriate parts might not b e re cycle d.
Contact with some of the mate ria ls
involved may pose a health hazard.
zWe re com mend that repair and
maintenance be entrusted to your O pel

Special equipment increases the weight of

max imum s pee d.
F or the first few thousa nd kilome tres/m ile s,

This increases fuel consump tion.
Fuel for petrol engines
Normal comme rc ia l hig h-q uality fue ls
with a m aximum ethanol conte nt of 5% in
accordance with DIN EN 22 8 are suitable
(Cataly tic converte r - s ee page 1 16 .
O ctane numbe rs - se e page 17 5 ). The
quality thereof has considerable effect on
performance, running and service life of
the e ngine. The additive s mixe d with the
fuel are extremely im portant. For this
r ea so n yo u mu s t o n ly r e fu e l with h igh-
quality fuels containing additives.Fuels with e thanol content of gre ater than
5% d o not com ply with DIN EN 228 and
must not be used unless the v ehicle has
bee n s pe cifica lly dev eloped a nd ap prov ed
for these fuels.
Fuel with too low an octane number can
cause pinking. Opel cannot b e held liable
for re sulting dam age.
Petrol with a higher octane number can
always be use d.
