Control of the vehicleNever coast with engine not
running
Many systems will not function in this
situation (e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur 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 may be higher during the running-in
period.

Driving and operating135Engine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
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.
Under certain driving conditions, e.g.
short distances, the system cannot
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
revolutions per minute. Shift down if
necessary. Diesel particle filter
cleaning is then started.
Stopping the journey or switching off
the engine during cleaning is not
recommended.
Caution
If the cleaning process is
interrupted more than once, there
is a great risk of provoking severe
engine damage.
Cleaning takes place quickest at high
engine speeds and loads.

Driving and operating151
Note
Attached parts in the detection area
cause system malfunction.
Activation
When reverse gear is engaged, the
system switches itself on
automatically.
The system can also be activated at
low speed by pressing the r button.
An obstacle is indicated by buzzers.
The interval between the buzzers
becomes shorter as the vehicle gets closer to the obstacle. When the
distance is less than 30 cm, the buzzer is continuous.
9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Deactivation
Deactivate the system by pressing
the r button.
The system deactivates automatically
when reverse gear is disengaged.
Towing equipment The system automatically detects
factory-fitted towing equipment.
When towing, plugging the trailer
cable into the socket automatically
switches the parking assist off.
Fuel
Fuel for petrol engines
Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable to run with
E10 fuel that fulfills these standards.
E10 fuel contains up to 10 %
bioethanol.
Use fuel with the recommended
octane rating 3 216. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly increases fuel consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.

Driving and operating153
Fuel filler flap is located at right rear
side of vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked. Pull flap at
the recess and open.
To open, turn the cap slowly to the left
The fuel filler cap can be retained in
the bracket on the fuel filler flap.
For refuelling, fully insert the pump
nozzle and switch it on.
After automatic cut-off, it can be
topped up with max. two doses of fuel.
Caution
Wipe off any overflowing fuel
immediately.
To close, turn the fuel filler cap to the right until it clicks.
Close the flap and let engage.
Fuel filler cap
Only a genuine fuel filler cap provides
full functionality. Diesel-engined
vehicles have special fuel filler caps.
Fuel consumption - CO 2-
Emissions The fuel consumption (combined) of
the model Opel Astra is within a range
of 7.3 to 5.0 l/100 km.
The CO
2 emission is within a range of
172 to 132 g/km.
General information
For the values specific to your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The determination of fuel
consumption is regulated by directive
R (EC) No. 715/2007 (in the latest
applicable version).
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.
Furthermore, fuel consumption is
dependent on personal driving style
as well as road and traffic conditions.
All values are based on the EU base
model with standard equipment.
The calculation of fuel consumption
takes into account the vehicle's kerb
weight, ascertained in accordance
with the regulations. Optional
equipment may result in slightly

154Driving and operating
higher fuel consumption and
CO 2 emission levels and a lower
maximum speed.Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Do not mount towing equipment to
vehicles with Z 20 LEH engine.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case, use the coupling ball bar for towing. Always keep the
coupling ball bar in the vehicle.
Installation dimensions of factory-
fitted towing equipment 3 232.Driving characteristics and
towing tips Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the
coupling ball, is being used to reduce snaking movements.
For trailers with low driving stability
and trailers with a permitted gross
vehicle weight of more than 1300 kg
(Saloon) /1200 kg (Station wagon) a
speed of 80 km/h must not be
exceeded; the use of a stabiliser is
recommended.
If the trailer starts snaking, drive more
slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 225.
