113Driving and operation
Overrun
z The fuel supply is automatically shut off
during overrun, e.g. when the vehicle is
being driven down long gradients or
when braking – see page 111.
z To enable the overrun cut-off to take
effect and sav e fuel, during overrun do
not accelerate and do not declutch.
Corr ect gear selec tion
z High revs increase engine w ear and fuel
consumption.
z Do not race your engine. Avoid driving at
high engine speeds.
Driv in g with an ey e on the tachom ete r
saves fuel. I f possib le, drive a t low revs in
each gear and a t a consta nt speed.
Drive in top gear as much a s p ossible,
shift up as soon as possible and do not
shift down until the engine is no longer
running truly.
High speed
z The faster the sp ee d, the h ighe r the fuel
consumption and the noise level. Driving
at full throttle uses up a great deal of fuel
and generates excessive noise and high
emission levels.
z Slightly relea sing the accelerator pedal
results in distinct fuel savings with no
major loss of speed.
Drive at no more tha n around three
quarters of maximum speed and you will
use up to 50% less fuel, without losing a
great deal of time.
Tyre pressure
z Inadequate tyre pressure, leading to
higher road resistance, costs m oney in
two wa ys: more fuel and increa sed tyre
wear.
z Regular checks (every 14 d ays) pay off.
Ele ctri cal loa ds
z The power consum ption of electrical
equipment increases fuel consumption.
z Sw itch off ad ditional consumers (e.g.
air conditioning, heated rear window)
when they are no longer required.
Repai r and maintenance
z Improper repairs or adjustment and
maintenance work can increase fuel
consumption. Do not carry out work on
the engine yourself.
You ma y infring e environmental la ws out
of ignorance by not disposing of
materials properly.
Appropriate parts might not be recycled.
Contact with some of the materia ls
involved may pose a health hazard.
z We recom mend that repair and
maintenance be entrusted to your Opel
Service Partner.
Extreme driving conditions
z Driving up steep gradients, cornering,
driving on poor roads and winter driving
all increase fuel consumption.
Fuel consumption increases dramatically
in urba n tra ffic a nd at win ter
temperatures, especially on short trips
when the e ngine operating tempe ra ture
is not reached.
z Follow the hints given above to keep
consumption to a minimum under such
cond itions.
