Provides a the greatest amount of comfort
in the interior regardless of the weather,
outside temperature or season.
To ensure a constant and comfortable
climate in the vehicle, the temperature of
the inflowing air, the air-flow rate and the
air distribution are changed automatically
according to climatic conditions outside
the vehicle.
The climate is regulated automatically
based on personal settings.
Picture no: 16500s.tif
Temperature changes due to external
influences, such as direct sunlight, are
automatically compensated.
When cooling (air conditioning
compressor) is active, air is cooled and
dehumidified.
The pollen filter removes dust, soot, pollen
and spores from the inflowing outside air.

When set to automatic mode, the climate
control system provides the optimal
settings for almost all conditions. If
necessary, climate control system settings
can be modified manually.
The climate control system is only
operational when the engine is running.
If you wish the climate control system 3 to
operate correctly, do not cover the sensor
on the instrument panel.

When the vehicle is stopped and the
ignition off, the residu al heat or cooling in
the system can be used for climate control
in passenger compartment, e.g. when
stopped at a level crossing.
Press AUTO with the ignition off. The
preselected temperature appears in the air
conditioning display. The temperature can
be adjusted with the left-hand rotary knob.
Residual climate control can only operate
for a limited period of time. To cancel,
press the AUTO button.
9 Warning
The exchange of fresh air is reduced in
air circulation mode. The quality of the
passenger compartment air
deteriorates which may cause the
vehicle occupants to feel drowsy. In
operation without cooling the air
humidity increases, so the windows may
mist up. Consequently, the air circulation
system should only be run for short
periods of time.

Driving and operation
Saving fuel, protecting the
environmentTrend-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 availabl
e at www.opel.com.
Energy and environment-conscious
driving
z High noise levels and exhaust emissions
are often a result of driving without due
attention to saving energy and
protecting the environment.
z You should therefore drive with energy in
mind: "more miles – 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
3224.
Check your vehicle’s fuel consumption
every time you refuel. This facilitates
early detection of any irregularities
causing increased fuel consumption. Warming up
z
Full 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.
z Drive off immediately after starting.
Warm up the engine by running it at
moderate engine speeds.
Uniform speed
z Hectic driving significantly increases fuel
consumption, the exhaust emissions, the
proportion of pollutant in the exhaust
gas and the noise level.
z Do 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
z The engine also consumes fuel when
idling.
z If 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.

138 Driving and operationOverrun
zThe fuel supply is shut off automatically
on overrun, e.g. when descending steep
hills or when braking 3136.
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 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 consumption by
approx. 1l/100 km.
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 Going 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.
z Follow the hints given above to keep
consumption to a minimum under such
conditions.
