Environmental
Protection
Trend-setting technology
Environmental protection plays an important
role in the research and design work carried
out by engineers at Adam Opel AG.
When developing and manufacturing your
vehicle, Opel used environment-friendly and
largely recyclable materials. The production
methods used to make your vehicle are
likewise environment-friendly.
Production wastes are recycled, with
materials being recovered for re-use.
Reduction of water requirements also helps to
conserve natural resources.

A highly advanced design means that your
vehicle can be easily disassembled and the
individual materials separated for subsequent
re-use.
Materials such as asbestos and cadmium are
not used.
New painting techniques employ water as a
solvent.
The pollutants contained in exhaust gas are
reduced.
As an Opel driver, you can make a major
contribution to protecting the environment:
I Save fuel when driving. The previous
section, entitled "Saving Fuel", gives you
numerous useful hints on this.
I Be conscious of the environment when
driving. The following section gives you
some further valuable hints in this regard.
Environment-conscious driving
I High noise levels and exhaust emissions
are often a result of driving without due
attention to the environment.
I Reduce the noise level and exhaust
emissions by adopting an environment-
conscious driving style. This is extremely
worthwhile and improves the quality of life.
Jackrabbit" starts, i.e. screeching of tyres
and high revs, can increase the noise level
up to four times over.
Select the next higher gear as soon as
possible. A vehicle travelling at 50 km/h
(30 mph) in second gear causes as much
noise as three vehicles driven at 50 km/h
(30 mph) in fourth.
Warming up
I Driving at full throttle or idling when the
engine is still cold increases fuel
consumption, exhaust emissions and
noise.
I Drive away immediately after starting.
Engine speed should be moderate until the
engine has reached operating temperature.
it By up to 18 dB(A).
dB: unit of noise level (decibel)
dB(A): standardized evaluation curve (frequency
evaluation curve) for relating objective measured i
values to the sensitivity of the human ear. An
increase in noise level of 10 dB(A) is registered as
a doubling of the volume.
