Good, te chnica lly  correct  and  economical

O verrun 
The fue l  supply  is  autom atically s hut  off 
during overrun, e.g.  when the  vehicle is 
be ing  driven down long gradie nts or whe n 
braking. To enable  the ove rrun cut-off 
to take  e ffe ct, do not acc elerate  during 
overrun and  do not  declutch. To prevent 
dam age  to the  cata ly tic conve rter,  ove rrun 
cut-off is temp orarily  de activate d whe n the 
cataly tic conv erte r tempe rature is  high.

Do  not a pply full throttle  until  the

the  s ele cted g ear incre ase s  wear  and  fue l

Change  dow n! 
When  decreasing  speed, shift down into 
the  next lowe st ge ar. Do not slip the  clutch 
with a high-re vving engine. This  is  
es pecially  important when hill climb ing.  
Clutch op era tion 
Alw ays dep ress the clutch pedal hard to 
the  floor to prev ent shifting difficultie s and 
tra ns mis sion dam age.
Whe n  driving, do not us e the  ped al as  a

The  cooling fan is  controlle d v ia a

Pedals 
Do not place  any  ob je cts  in the  foot we ll 
which could slip under the ped als  and  
inhibit the pe dal trav el. 
To ensure the pedal travel is  uninhibited, 
there  must be  no  unre strained  mats in the  
are a of the p edals .
Bat tery ca re 
W hen driving slowly or whe n the v ehicle is 
stationary, e.g. in slow urban traffic, stop-
and-go traffic or traffic jams, turn off all 
unnecessary electrical  load s w here 
pos sible  (e. g. he ated re ar window).

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  –

zDo not  accele rate a nd  brake  
unnecessarily . Drive at uniform  speed.  
Avoid frequent starting-off and

Fuel c onsum ption
Fuel consump tion is determined  und er 
s pecific driv ing  cond itions  – s ee  page 1 77 . 
Special equipment increases  the weight  of 
t h e v eh i cl e.  A s  a  r es u l t , t h ey  ca n  i n cr ea s e  
fuel consump tion and reduce the specified  
max imum s pee d. 
F or the first few  thousa nd kilome tres/m ile s, 
friction b etwe en the  engine  and  
transm ission com pone nts is higher.  
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. 
The  ignition tim ing adjusts automatically

Use  of pe trol with an octane  rating of 95 or
