Instruments and controls791 off:natural gas
operation1 illuminates:petrol operation
As soon as the natural gas tanks are
empty, petrol operation is
automatically engaged. Control
indicator Y illuminates in the Driver
Information Centre 3 91 until the
ignition is switched off.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.
Every six months run the petrol tank
down until control indicator §
illuminates and then refuel. This is
necessary 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.
Fuel for natural gas operation 3 136.
Refuelling 3 136.
Engine coolant temperature
gauge
Displays the coolant temperature.
If control indicator $ illuminates, the
coolant temperature is too high.
Depending on version, a message
also appears in the Driver Information Centre 3 91. Seek the assistance of
a workshop.
Caution
If engine coolant temperature is
too high, stop vehicle, switch off
engine. Danger to engine. Check
coolant level.
Service display
Service display is available in
vehicles with Multifunction version of the Driver Information Centre 3 91.
When the ignition is switched on, the remaining distance before the next
service is due may be shown briefly.

Autostop
If the vehicle is at a low speed or at a standstill, activate an Autostop as
follows:
● depress the clutch pedal
● set the lever to neutral
● release the clutch pedal
The engine will be switched off while the ignition stays on.
An Autostop is indicated when control
indicator ^ flashes in the Driver
Information Centre 3 91.
During an Autostop, the heating,
power steering and brake
performance will be maintained.
Caution
The power steering assist may be
reduced during an Autostop.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
Otherwise an Autostop will be
inhibited.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the driver's door is closed and the
driver's seat belt is fastened
● the vehicle battery is sufficiently charged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the engine exhaust temperature is not too high, e.g. after driving
with high engine load
● the ambient temperature is not too low
● the climate control system allows
an Autostop

Accessories and vehiclemodifications
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 warrantyoffered 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.

142Vehicle careCaution
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 to 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
locking 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 plates if necessary.End-of-life vehicle recovery
Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our website. Only entrust this work to an
authorised recycling centre.
Natural gas vehicles must be recycled by a service centre authorised for
natural gas vehicles.

Vehicle care145Capacities 3 190.
Fit the cap on straight and tighten it.
Engine coolant
The coolant provides freeze
protection down to approx. -28 °C. In
cold regions with very low
temperatures, the factory filled
coolant provides frost protection
down to approx. -37 °C.Caution
Only use approved antifreeze.
Coolant and antifreeze 3 178.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be between the
MIN and MAX mark. Top up if the
level is low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up, use a 1:1 mixture of
approved coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Coolant and antifreeze 3 178.
Power steering fluidCaution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not
work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap/dipstick or
from entering the reservoir.

Service and maintenance179Dexos is the newest engine oil quality
that provides optimum protection for
petrol and diesel engines. If it is
unavailable, engine oils of other listed qualities must be used.
Recommendations for petrol engines
are also valid for Compressed Natural
Gas (CNG) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 182.
Topping up engine oilCaution
In case of any spilled oil, wipe it up and dispose it properly.
Engine oils of different manufacturersand brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 182.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity
The SAE viscosity grade gives
information on the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 182.
All of the recommended viscosity grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only antifreeze approved for the
vehicle. Consult a workshop.The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
regions with very low temperatures,
the factory filled coolant provides frost
protection down to approx. -37 °C.
This concentration should be
maintained all year round.
The use of additional coolant
additives that intend to give additional corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional
coolant additives will be rejected.
Washer fluid Use only washer fluid approved for
the vehicle to prevent damage of wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.
Brake and clutch fluid Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified interval.
