Driving and operating141Driving hints
Control of the vehicle
Never coast with engine not
running (except during Autostop)
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. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 143.
Idle boost
If charging of the vehicle battery is
required due to battery condition, the
power output of the generator must be increased. This will be achieved by an idle boost which may be audible.
A message is displayed in the Driver Information Centre.Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Use only floor mats which fit properly and are fixed by the retainers on the
driver's side.
Steering If power steering assist is lost
because the engine stops or due to a
system malfunction, the vehicle can
be steered but may require increased
effort.
Control indicator c 3 90.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
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.
During the running-in period fuel and engine oil consumption may be
higher and the cleaning process of the exhaust filter may take place more
often. Autostop may be inhibited to
allow for charging the battery.
Exhaust filter 3 146.

Driving and operating147Automatic cleaning processThe exhaust filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
take up to 25 minutes. Typically it
needs between seven and twelve
minutes. Autostop is not available
and fuel consumption may be higher
during this period. The emission of
smells and smoke during this process is normal.System requires cleaning
Under certain conditions, e.g. driving
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and if previous driving conditions did not
enable automatic cleaning, it will be
indicated by illumination of % and a
warning message in the Driver
Information Centre.
% illuminates along with a warning
message when exhaust filter is full.
Start cleaning process as soon as
possible.
% flashes along with a warning
message when exhaust filter has
reached the maximum filling level.
Start cleaning process immediately to
avoid damage to the engine.
Activate self-cleaning process
To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm. Shift down if
necessary. Exhaust filter cleaning is
then started.
Cleaning process is completed more quickly at high engine speeds and
loads.
Control indicator % extinguishes as
soon as the self-cleaning operation is complete. Keep on driving until self-
cleaning operation is complete.Caution
If possible, do not interrupt
cleaning process. Drive until
cleaning is completed to avoid the
need for service or repair by a
workshop.

Driving and operating189The system can not operate when no
lane marking is detected.Fuel
Fuel for petrol engines
Only use unleaded fuel that complies
with European standard EN 228 or
equivalent.
The engine is capable of running with
fuel that contains up to 10% ethanol
(e.g. named E10).
Use fuel with the recommended
octane rating. A lower 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.
Caution
Use of fuel that does not comply to EN 228 or equivalent can lead to
deposits or engine damage.
Caution
Use of fuel with a lower octane
rating than the lowest possible
rating could lead to uncontrolled combustion and engine damage.
The engine specific requirements
regarding octane rating are given in
the engine data overview 3 263. A
country specific label at the fuel filler
flap can supersede the requirement.

Vehicle care201General Information
Accessories and vehicle modifications
We recommend the use of genuine
parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Any modification, conversion or other changes made to standard vehicle
specifications (including, without
limitation, software modifications,
modifications of the electronic control
units) may invalidate the warranty
offered by Opel. Furthermore, such
changes may affect driver assistance systems, may impact fuel
consumption, CO 2 emissions and
other emissions of the vehicle and
cause the vehicle to no longer
conform to the operating permit,
impacting the validity of your vehicle
registration.Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
If the vehicle is to be stored for several months:
● Wash and wax the vehicle.
● Have the wax in the engine compartment and underbody
checked.
● Clean and preserve the rubber seals.
● Fill up fuel tank completely.
● Change the engine oil.
● Drain the washer fluid reservoir.
● Check the coolant antifreeze and
corrosion protection.
● Adjust tyre pressure to the value specified for full load.
● Park the vehicle in a dry, wellventilated place. Engage first or
reverse gear or set selector lever
to P. Prevent the vehicle from
rolling.
● Do not apply the parking brake.
● Open the bonnet, close all doors and lock the vehicle.
● Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems
are not functional, e.g. anti-theft
alarm system.
Putting back into operation
When the vehicle is to be put back into
operation:
● Connect the clamp to the negative terminal of the vehicle
battery. Activate the electronics
of the power windows.
● Check tyre pressure.
● Fill up the washer fluid reservoir.
● Check the engine oil level.
● Check the coolant level.
● Fit the number plate if necessary.

Vehicle care231Tyre pressure
Check the pressure of cold tyres at least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Tyre pressure 3 270.
The tyre pressure information label
on the front left or right door frame
indicates the original equipment tyres
and the correspondent tyre
pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the body style.
2. Identify the engine identifier code.
Engine data 3 263.
3. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 270.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
