Air intake The air intakes in front of the windscreen on
the far left and right-hand sides of the
engine compartment must be kept free of
leaves, dirt and snow so as not to obstruct
the air supply. Air outletDo not cover the air outlets when stowing
objects in the luggage compartment. Pollen filter The pollen filter cleans dust, soot, pollen
and spores from the air entering from
outside. The active carbon layer 3
eliminates most odours and noxious
environmental gases from the air.
Regular operationTo make sure that the AC compressor
is constantly working well, the cooling
system3 must be switched on several
minutes once a month regardless of the
weather or season. It is not possible to
activate cooling when outside
temperatures are low. Service For optimal cooling performance, we
recommend that the climate control
system be checked annually, starting
three years after initial vehicle registration.

106 Driving and operationDriving hints The first 1000 km
Drive your vehicle at various speeds. Do
not use full throttle. Never allow the engine
to labour at low revs.
Change gear frequently. Do not press the
accelerator pedal more than approx.
3/4 in
all gears.
Do not drive faster than three quarters of
maximum speed.
Do not brake unnecessarily hard for the
first 200 km.
During the first drive, smoke may develop
because of wax and oil evaporating off the
exhaust system. Park the vehicle in the
open for a while after the first drive and
avoid inhaling the fumes.
Fuel and engine oil consumption is higher
than normal during the running-in period.
Never coast with engine not running
Many units will not function in this situation
(e.g. brake servo unit, power steering3).
Driving in this manner is a danger to
yourself and others. Brake servo unit
When the engine is not running, the brake
servo unit is no longer effective once the
brake pedal has been depressed once or
twice. Braking effect is not reduced, but
significantly greater force is required for
braking.
Electric power steering 3
If the power-assisted steering fails when
being towed with the engine switched off –
the vehicle can still be steered, but
considerably more force is required.
Driving in mountainous terrain or with a
trailer/caravan
The cooling fan is electrically operated. Its
cooling power is therefore independent of
the engine speed.
Since a considerable amount of heat is
generated at high engine speeds and less
at slower speeds, do not shift down when
climbing hills whilst the vehicle is still coping
with the gradient in the higher gear.
Diesel engines: On gradients of 10 % or
more, do not drive faster than 30 km/h in
first gear or 50 km/h in second gear. Driving with a roof load
Do not exceed the permissible roof load,
3189. For reasons of safety, distribute the
load evenly and strap it down firmly using
retaining straps so that it cannot slip.
Check the tyre pressure when the vehicle is
loaded. Do not travel faster than 120 km/h.
Check and re-tighten the straps frequently.
Observe country-specific regulations.
Switching off the engine
When you switch off, fans in the engine
compartment may continue running for a
time to cool the engine.
If the engine temperature is very high, e.g.
after driving in mountainous terrain: allow
the engine to idle for approximately two
minutes in order to prevent heat
accumulation.
Vehicles with turbocharged engine

After running at high engine speeds or high
engine loads, operate the engine briefly at
a low load or run in neutral for approx.
30 seconds before switching off in order
to protect the turbocharger.

108 Driving and operationSaving Fuel, Protecting the
Environment Trend-setting technology
Environmentally friendly and mainly
recyclable materials were used when your
vehicle was being developed and
manufactured. The production methods
used to make your vehicle are also
environmentally-compatible.
Recycling of production wastes keeps the
circulation of material closed. Reduction of
energy and water requirements also helps
to conserve natural resources.
A highly advanced design means that your
vehicle can be easily disassembled at the
end of its working life, and the individual
materials separated for subsequent re-use.
Materials such as asbestos and cadmium
are not used. The refrigerant in the air
conditioning system 3 is CFC-free.
New painting techniques employ water as
a solvent. End-of-life vehicle recovery
Information on end-of-life vehicle recovery
centres and the recycling of end-of-life
vehicles is available at www.opel.com.
Energy and environment-conscious
driving
zHigh noise levels and exhaust emissions
are often a result of driving without due
attention to saving energy and
protecting the environment.
zYou should therefore drive with energy in
mind: "more kilometres – less fuel".
Reduce the noise level and exhaust
emissions by adopting an environment-
conscious driving style. This is extremely
worthwhile and improves the quality of
life.
Fuel consumption depends to a great
extent on your own personal driving
style. The following hints are intended to
help you consume fuel at a rate that is as
close as possible to the specified levels
3186.
Check your vehicle’s fuel consumption
every time you refuel. This facilitates
early detection of any irregularities
causing increased fuel consumption. Warming up
zFull throttle and warming up at idle
speed increase wear, fuel consumption,
exhaust emission, the amount of
pollutant in the exhaust and the amount
of noise.
zDrive off immediately after starting.
Warm up the engine by running it at
moderate engine speeds.
Uniform speed
zHectic driving significantly increases fuel
consumption, the exhaust emissions, the
proportion of pollutant in the exhaust
gas and the noise level.
zDo not accelerate and brake
unnecessarily. Drive at uniform speed,
watching the road.
Avoid frequent starting off and stopping
e.g. at traffic lights, in short distance
traffic and in queues of traffic by means
of clever planning. Select roads with
good traffic flow.
Idling
zThe engine also consumes fuel when
idling.
zIf you have to wait for more than one
minute, it is worthwhile switching off the
engine. Five minutes of idling
corresponds to approximately one
kilometre of driving.

109
Driving and operation
Overrun
zThe fuel supply is automatically shut off
during overrun, e.g. when the vehicle is
being driven down long gradients or
when braking 3107.
zTo enable the overrun cut-off to come
into action and save fuel, do not
accelerate or declutch during overrun.
Correct gear selection
zHigh revs increase engine wear and fuel
consumption.
zDo 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
zThe 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. zSlightly 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
zInadequate tyre pressure, leading to
higher road resistance, costs money in
two ways: for more fuel and increased
tyre wear.
zRegular checks (every 14 days) pay off.
Electrical loads
zThe power consumption of electrical
equipment increases fuel consumption.
zSwitch off all auxiliary electrical loads
(e.g. air conditioning3, heated rear
window) when not needed.
Roof racks
zDue to air resistance, a roof load can
increase fuel consumption by approx.
1 l/100 km.
zRemove them if they are not being used. Repair and maintenance
zImproper 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.
zWe recommend that repair and
maintenance be entrusted to your Opel
Partner.
Extreme driving conditions
zGoing up steep slopes, cornering, driving
on poor roads and winter driving all
increase fuel consumption.
Fuel consumption increases dramatically
in urban traffic and at winter
temperatures, especially on short trips
when the engine operating temperature
is not reached.
zFollowing the instructions given above
will minimise consumption under these
conditions.

Control indicator
A
for engine electronics

Illuminates for a few seconds when ignition
is switched on.
If it comes on when the engine is running,
there is a fault in the engine or transmission
electronics. The electronics switch to the
emergency running programme, fuel
consumption may increase and the
driveability of the vehicle may be affected.
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 engine 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 illuminates, there may be water in the
diesel fuel filter 3. Have the fuel filter
checked for water residue by a workshop
3177.
I f i t f l a s h e s a f t e r t h e i g n i t i o n i s s w i t c h e d o n ,
there is a fault in the immobiliser system.
The engine cannot be started 321.
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 high 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.
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 an open tailgate.
Otherwise, exhaust gases could get into
the interior.
