Driving and operation
Driving hintsThe first 1000 km
Drive your vehicle at various speeds. Do
not use full throttle. Never allow the engine
to labour at low revs.
Drive moderately. In all gears, only depress
the accelerator pedal around
3/4 of the way
down.
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 on 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 steering 3).
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 elec trically 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. Driving with a roof load
Do not exceed the permissible roof load
3
226. For reasons of safety, distribute the
load evenly and secure it properly with
retaining straps. Adjust tyre pressure to
load conditions. Do not drive faster
than 120 km/h. Check and retighten 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
3
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.

136 Driving and operationSave energy – more kilometres
Please observe the running-in hints on the
previous page and the tips for energy
saving on the following pages.
Good, technically correct and economical
driving ensures maximum durability and
performance for your vehicle.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, e.g. when the vehicle is
driven with a gear engaged but no throttle
application. Overrun cut-off is deactivated
if catalytic converter temperature is high.
Vehicles with turbocharged engine
3
Flow-generated noises may be audible if
the accelerator is released quickly on
account of air flow in the turbocharger.
Engine speed
Drive in a low engine speed range for each
gear as much as possible. Warming up
Allow the engine to wa
rm up while driving.
Do not warm it up by letting it ru n at idling
speed. Do not apply full throttle until the
engine has reached operating
temperature.
After a cold start, the manual transmission
automated 3 does not switch to higher
gears until the speed increases when it is in
automatic mode. This allows the catalytic
converter to reach th e temperature quickly
which is required for optimum emission
reduction.
Correct gear selection
Do not race your engine whilst in neutral or
with a low gear selected. Driving too fast in
individual gears as well as stop-and-go
traffic increases engine wear and fuel
consumption.
Change down
When decreasing speed, shift down into
the next lowest gear. Do not slip the clutch
with a high-revving engine. This is
especially important when hill climbing. Cooling fan
The cooling fan is controlled via a
thermoswitch and therefore only runs if
necessary.
The cooling fan automatically switches on
when the diesel particle filter is being
cleaned
3 depending on the engine.
Pedals
Do not place any objects in the foot well
which could slip under the pedals and
inhibit the pedal travel.
To ensure the pedal travel is uninhibited,
there must be no mats in the area of the
pedals.
Battery care
When driving slowly or when the vehicle is
stationary, e.g. in slow urban traffic, stop-
and-go traffic or traffic jams, turn off all
unnecessary electrical loads where
possible (e.g. heated rear window, heated
front seats, etc.).
Declutch when starting in order to relieve
the strain on the starter and the battery.

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.

139
Driving and operation
Fuels, refuellingFuel consumption
The fuel consumption is determined under
specified driving conditions 3224.
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
3220). 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 filterability of diesel fuel are
temperature-dependent. When
temperatures are low, re
fuel with diesel fuel
with guaranteed winter properties.
Caution
Use of fuel with too low an octane rating
could lead to uncontrolled combustion
and engine damage.
