Operation Manual

Driv in g and op e ra tio n126
Overrun
z The fuel supply is automatically shut off
during overrun, e.g. when the vehicle is
being driven down long gradients or
during b raking - see page 124.
z To enable the overrun cut-off to take
effect and save fuel, do not accelerate or
declutch.
Corr ect gear selec tion
z High revs increase engine wear and fuel
consumption.
z Do not race your engine. Avoid driving at
high engine speeds.
Driv ing with an ey e on the tachom ete r
saves fuel. I f possib le , drive a t low rev s in
each gear and at a consta nt speed.
Drive in top g ear as much as p ossible,
shift up as soon as possible and do not
shift down prematurely.
High speed
z The faster the speed, the higher the fuel
consumption and noise level. Driving at
full throttle uses up a great deal of fuel
and generates excessive noise and high
emission levels.
z Slightly releasing the accelerator pedal
results in distinct fuel savings with no
major loss of speed.
Drive at no more than 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 ways; for more fuel and increased
tyre wear.
z Regular checks (every 14 d ays) pay off.
Ele ctri cal loa ds
z The power consumption of electrical
equipment increases fuel consumption.
z Switch off all additional consumers (e.g.
air conditioning, heated rear window)
when they are no longer required.
Roof racks 3
z Roof racks can increase fuel
consump tion by approx.
3.5 gal./1000 miles (1 l/100 km)
due to air resistance.
z Remove them if they are not being used.
Repair and m aintenance
z Improper repairs or adjustment 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 m ight not be recycled .
Contact with some of the materials
involved may pose a health hazard.
z We recom mend that repairs and
maintenance be entrusted to a Vauxhall
Authorised Repairer.
Extr em e d riving 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 winter
temperatures, especially on short trips
when the e ngine operating tempe ra ture
is not reached.
z Follow the hints given above to keep fuel
consumption to a minimum under such
conditions.
