Instruments and controls105Fuel selector
Natural gas operation, CNG
Pressing Y switches between petrol
and natural gas operation. Switching
is not possible at high loads (e.g.
powerful acceleration, driving at full
throttle). The LED status shows the
current operating mode.
1 off:natural gas
operation1 illumi‐
nates:petrol operation1 flashes:no switching is
possible, one type of
fuel is emptyAs soon as the natural gas tank is
empty, petrol operation is
automatically engaged until the
ignition is switched off.
If the natural gas tank is not refuelled, the system must be manually
switched to petrol operation before
the engine is restarted. This will
prevent damage to the catalytic
converter (overheating caused by
irregular fuel supply).
If the selector switch is operated
several times within a short time, a
switchover inhibitor is activated. The
engine remains in the current
operating mode. The inhibitor
remains active until the ignition is
switched off.
A slight loss of power and torque can
be expected during petrol operation.
You must therefore adapt your driving style (e.g. during overtaking
manoeuvres) and high vehicle loads
(e.g. towing loads) accordingly.
Every six months run the petrol tank
down until control indicator Y
illuminates, then refuel. This isnecessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Note
Natural gas tanks (Type IV) consist
of lightweight fibre reinforced plastic.
After a collision behind the front
seats or overrunning of objects
which impact the underbody of the vehicle the natural gas tanks must
be checked. We recommend an
Opel Repairer authorised for
servicing natural gas vehicles.

200Driving and operatingTurn key briefly to position 3 and
release: an automatic procedure
operates the starter with a short delay
until the engine is running, see
Automatic Starter Control.
Manual transmission: during an
Autostop, the engine can be started
by depressing the clutch pedal
3 201.
Automatic transmission: during an
Autostop, the engine can be started
by releasing the brake pedal 3 201.
Before restarting or to switch off the engine, turn the key back to position
0 .9 Danger
Switching off the engine during
driving may cause loss of power
support for brake and steering
systems. Assistance systems and
airbag systems are disabled.
Lighting and brake lights will
extinguish. Therefore power down
the engine and ignition while
driving only when required in case of emergency.
Starting the vehicle at low
temperatures
The start of the engine without
additional heaters is possible down to -25 °С for diesel engines and -30 °C
for petrol engines. Required is an engine oil with the correct viscosity,
the correct fuel, performed services
and a sufficiently charged battery.
With temperatures below -30 °C the
automatic transmission need a
warming phase of approx. five
minutes. The selector lever must be
in position P.
Automatic Starter Control This function controls the engine
starting procedure. The driver does
not have to hold the key in position 3.
Once applied, the system will go on
starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running
after a short delay.Possible reasons for a non-starting
engine:
● Clutch pedal not operated (manual transmission).
● Brake pedal not operated or selector lever not in P or N
(automatic transmission).
● Timeout occurred.
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time,
especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.
Overrun cut-off The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but accelerator pedal is released.
Depending on driving conditions, the
overrun cut-off may be deactivated.

Driving and operating245Fault
The lane departure warning system may not operate properly when:
● The windscreen is not clean.● There are adverse environmental
conditions like heavy rain, snow,
direct sunlight or shadows.
The 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 3 312. A
country specific label at the fuel filler
flap can supersede the requirement.

292Vehicle care4. Ensure the jack is correctlypositioned under the relevant
vehicle jacking point.
5. Set the jack to the necessary height. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Attach wheel wrench and with the
jack correctly aligned rotate wheel wrench until wheel is clear of the
ground.
6. Unscrew the wheel nuts. 7. Change the wheel. Spare wheel 3 293
8. Screw on the wheel nuts.
9. Lower the vehicle and remove jack.
10. Install the wheel wrench ensuring that it is located securely and
tighten each nut in a crosswise
sequence. Tightening torque is
140 Nm.
11. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
12. Install vehicle jacking point cover.
13. Stow the replaced wheel 3 293,
the vehicle tools 3 281 and the
adapter for the locking wheel nuts
3 66.
14. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.
Have the defective tyre renewed or
repaired as soon as possible.
