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 139.
z To enable the overrun cut-off to come
into action and save fuel, do not
accelerate or d eclutch during overrun.
Correct gear selection
z High revs increase engine w ear and fuel
consumption.
z Do not race your engine. Avoid driving at
high engine speeds.
Making use of the tachom eter helps to
save fuel. Drive in a low engine spee d
ra nge for each gear as much a s possible
with uniform engine speeds. Drive as
often as possible in top gear, select the
next higher gear as soon as possible,
and only change down when the engine
is no longer running perfectly smoothly.
High speed
z The higher the speed, the higher the
consumption and the noise level. At top
speed, you consume a great deal of fuel
and produce excessive noise and
exhaust emissions.
z Slightly releasing the accelerator ped al
results in distinct fuel savings with no
major loss of speed.
Drive at no more than around three
quarters of max imum speed and you will
use up to 50 % less fuel, without losing a
great deal of time.
Tyre pre ssu re
z Inadequate tyre pressure, leading to
higher road resistance, costs m oney in
two wa ys: For m ore fuel and increased
tyre wear.
z Regular checks (every 14 d ays) pay off.
Electrical lo ads
z The power consumption of electrical
equipment increases fuel consumption.
z Sw itch off all auxiliary electrical loads
(e. g. air conditioning 3, heated rear
window) when not needed.
Roof racks, ski-holders
z Due to air resistance, a roof load can
increase fuel consump tion by approx.
3.5 gal/1000 miles (1 l/100 km).
z Remove them if they are not being used.
Repair and maintenance
z Improper repairs or adjustm ent and
maintenance work can increase fuel
consumption. Do not carry out work on
the engine yourself.
You may out of ignorance infringe
environmental law s b y not disposing of
materials properly.
Appropriate parts might not b e recycled.
Contact with some of the materials
involved may pose a health hazard.
z We recom mend that repair and
maintenance be entrusted to your
Vauxhall Authorised Repairer.
Extre me drivin g con ditio ns
z Going up steep slopes, cornering, driving
on poor road s a nd winter driving a ll
increase fuel consumption.
Fuel consumption increa ses dramatically
in urba n t ra ffic a nd at win ter
temperatures, especially on short trip s
when the e ngine operating te mpe ra ture
is not reached.
z Follow the hints given above to keep
consumption to a minimum under such
cond itions.
