2009 OPEL CORSA fuel consumption

152 Driving and operationOverrun
zThe fuel supply is shut off automatically
on overrun, e.g. when descending steep
hills or when braking 3150.
z To enable the overrun cut-off to come
into action and save fuel, do not
accelerate or declutch during overrun.
Correct gear selection
z High revs increase engine wear and fuel
consumption.
z Do not race your engine. Avoid driving at
high engine speeds.
Making use of the tachometer helps to
save fuel. Drive in a low engine speed
range for each gear as much as 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 th e accelerator pedal
results in distinct fu el 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 money in
two ways: for more fuel and increased
tyre wear.
z Regular checks (every 14 days) pay off.
Electrical loads
z The power consumption of electrical
equipment increases fuel consumption.
z Switch off all additional consumers (e.g.
air conditioning 3, heated rear window)
when not needed.
Roof racks, ski-holders
z Roof loads can increase fuel consumption
by approximately 1l/100 km due to air
resistance.
z Remove them if they are not being used. Repair and maintenance
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 laws by not disposing of
materials properly.
Appropriate parts might not be recycled.
Contact with some of the materials
involved may pose a health hazard.
z We recommend that repair and
maintenance be entrusted to your Opel
Partner.
Extreme driving conditions
z Driving up steep slopes, cornering,
driving on poor roads and driving in ice
and snow all increase fuel consumption.
Fuel consumption increases dramatically
in urban traffic and at low temperatures,
especially on short trips when the engine
operating temperature is not reached.
z Following the instructions given above
will minimise consumption under these
conditions.

Driving and operation
Fuels, refuelling Fuel consumption
Fuel consumption is determined under
specific driving conditions – see page
3256.
Special equipment increases the weight of
the vehicle. As a result, they can increase
fuel consumption and reduce the specified
maximum speed.
For the first few thousand kilometres,
friction between the engine and
transmission components is higher. This
increases fuel consumption.
Fuel for petrol engines
Only use unleaded fuel that complies
with DIN EN 228.
Fuels with ethanol content greater than 5 %
may only be used if the vehicle has been
specifically developed and approved for
these fuels.
Use fuel with the recommended octane
rating (value in bold 3254). Use of fuel
with too low an octane rating can reduce
engine power and torque and will slightly
increase fuel consumption. Fuel for diesel engines
Only use diesel fuel that complies
with DIN EN 590. The fuel must have
low sulphur content (maximum 50 ppm).
Do not use marine diesel oils, heating oils
or entirely or partially plant-based diesel
fuels, such as rape seed oil or bio diesel,
Aquazole and similar diesel-water
emulsions. Diesel fuels must not be diluted
with fuels for petrol engines.
The flow and filterabilit
y of diesel fuel are
temperature-dependent. When
temperatures are low, refuel with diesel fuel
with guaranteed wi nter properties.

Fuel filler cap
Only a Opel Genuine fuel filler cap provides
full functionality. Di esel-engined vehicles
have special fuel filler caps.
Refuelling
Caution
Use of fuel with too low an octane rating
could lead to uncontrolled combustion
and engine damage.
9
Warning
Before refuelling, switch off engine and
any external heater s with combustion
chambers 3 (identified by sticker on tank
flap). Switch off any mobile phones.
Follow the operating and safety instruc-
tions of the filling stat ion when refueling.

Picture no: 18251s.tif
Control indicator
Z for exhaust
Illuminates when the ignition is switched on
and during the start attempt. Goes off
shortly after the engine starts running.
Illumination whilst the engine is running
indicates a fault in the emission control
system. The permissible emission limits
may be exceeded. Contact a workshop for
assistance immediately.
Illumination with the engine running
indicates a fault that can cause damage to
the catalytic converter. It is possible to
continue driving without causing damage
by slowing down until the flashing stops
and the control indicator illuminates.
Contact a workshop for assistance
immediately.
Picture no: 18231s.tif
Control indicator
A
for engine electronics
Illuminates for a few seconds after the
ignition is switched on.
If it illuminates when the engine is running,
there is a fault in engine or transmission
electronics. The electr onic system switches
to an emergency runni ng programme. Fuel
consumption may be increased and the
driveability of the vehicle may be impaired.
In some cases the fault can be remedied by
switching the engine off and starting it
again. If the control indicator continues to
illuminate whilst the en gine is running,
contact a workshop for assistance in
remedying the cause of the fault. If it illuminates briefly, but does not recur, it
is of no significance.
If
A lights up, this could mean that there
is water in the diesel fuel filter 3. A
message appears at the same time on the
service display 391. Have the fuel filter
checked for possible water contamination
by a workshop.
If it flashes after the ignition is switched on,
there is a fault in the immobiliser system.
The engine cannot be started 327.

Driving and operation
Engine exhaust Diesel particle filter 3
The diesel particle filter system filters
harmful soot particles out of the exhaust
gases. The system includes a self-cleaning
function that run automatically during
driving. The filter is cleaned by burning off
the soot particles at hi gh temperature. This
process takes place automatically under
set driving conditions and may take up
to 25 minutes. Fuel consumption may be
higher during this period. The emission of
smells and smoke during this process is
normal.
Picture no: 18544s.tif
Under certain driving conditions, e.g. short
journeys, the system may not clean itself
automatically.
If the filter requires cleaning and previous
driving conditions did not enable
automatic cleaning, control indicator !
flashes. Continue driving, keeping engine
speed above 2000 rpm
-1. Shift down if
necessary. Diesel partic le filter cleaning is
then initiated.
9
Warning
Engine exhaust gases contain poisonous
carbon monoxide, which is colourless
and odourless and could be fatal if
inhaled.
If exhaust gases penetrate the vehicle,
open windows and contact a workshop
for assistance.
Avoid driving with the tailgate open,
since exhaust gas can enter the interior
of the vehicle.

256 Technical DataFuel consumption, CO
2-emissions
Directive 80/1268/EEC (last changed
by 2004/3/EC) has applied for the
measurement of fuel consumption
since 1996.The directive is oriented to actual driving
practices: Urban driving is rated at
approx.
1/3 and off-road driving with
approx.2/3 (urban and extra-urban
consumption). Cold starts and acceleration
phases are also taken into consideration.
The specification of CO
2-emission is also
a constituent of the directive. The figures given must not be taken as a
guarantee for the actual fuel consumption
of a particular vehicle.
All values are based on the EU base model
with standard equipment.
The calculation of fuel consumption as
specified by directive 2004/3/EC takes
account of the vehicle’s kerb weight,
ascertained in accordance with the said
regulation. Optional ex
tras may result in
slightly higher fuel consumption and
CO
2-emission levels than those quoted.
