2018 OPEL COMBO D fuel cap

78Instruments and controlsFuel gauge
Displays the fuel level or gas level in
the tank depending on the operation
mode.
During natural gas operation, the
system automatically switches over to
petrol operation when the gas tanks
are empty 3 78.
Fuel selector 3 136.
Control indicator $ illuminates if the
level in the tank is low.
Note
The symbol k beside Y indicates
that the fuel filler flap is located on
the left side of the vehicle.
Never run the tank dry.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified tank capacity.
The needle will point to 0 and control
indicator $ will flash to indicate a fault
in the system. Seek the assistance of a workshop.
Low fuel control indicator $ 3 89.
CNG fuel gauge
In natural gas operation mode, the
four vertical bars next to CNG
correspond to the methane level in
the cylinders. As the fuel level
diminishes, the bars in the CNG fuel
gauge disappear.
CNG and the one remaining bar will
flash if the methane level in the
cylinders is low.
Refuelling 3 136.
Fuel selector
Pressing Y in the centre console
switches between petrol and natural
gas operation. The LED 1 status
shows the current operating mode.

Driving and operating135Fuel
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 todeposits 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 3 183. A
country-specific label at the fuel filler
flap can supersede the requirement.
Fuel for diesel engines Only use diesel fuel that complies
with EN 590 and which has a sulphur
concentration of max. 10 ppm.
Fuels with a biodiesel (compliant with
EN 14214) content of max. 7% by
volume may be used (e.g. named
B7).
If travelling in countries outside the
European Union occasional use of Euro-Diesel fuel with a sulphur
concentration below 50 ppm is
possible.Caution
Frequent usage of diesel fuel containing more than 15 ppm
sulphur will cause severe engine
damage.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.

136Driving and operatingLow temperature operation
At temperatures below 0° C, some diesel products with biodiesel blends
may clog, freeze or gel, which may
affect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0°C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20° C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage on the fuel
injection system.
Fuel for natural gasoperation
Use natural gas with a methane
content of approx. 78 - 99%. L-gas
(low) has approx. 78 - 87% and H-gas (high) has approx. 87 - 99%. Biogas
with the same methane content can
also be used if it has been chemically
prepared and desulphurised.
Only use natural gas or biogas that complies with DIN 51624.Liquid gas or LPG must not be used.
Refuelling
Fuel filler flap is located at left rear
side of vehicle.9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Caution
In case of misfuelling, do not
switch on ignition.
Release the fuel filler flap by pulling
the flap by hand.
Insert ignition key into fuel filler cap
and turn anticlockwise to unlock.
To remove fuel filler cap, rotate
anticlockwise.
Caution
To avoid damage, do not attempt
to operate the sliding side door
when the fuel filler flap is open.
Note
Depending on model, the sliding
side door may be fitted with a safety system that prevents the door from
being opened fully when the fuel
filler flap is open.
Sliding side door 3 26.

Driving and operating137
The fuel filler cap can be retained in
the bracket on the fuel filler flap.
To refuel, fully insert the pump nozzle
and switch it on.
After automatic cut-off, the tank can be topped up by operating the pump
nozzle a maximum of two more times.
Caution
Wipe off any overflowing fuel
immediately.
To close, replace fuel filler cap and
turn clockwise.
Insert ignition key into fuel filler cap
and turn clockwise to lock, then
remove key.
Close the fuel filler flap.
Natural gas refuelling
Open the fuel filler flap.
9 Warning
Refuel only with a maximum
output pressure of 250 bar. Use
only temperature compensated
filling stations.
The refuelling procedure must be
completed, i.e. the filler neck must be vented.
The capacity of the natural gas tank
depends on outside temperature,
filling pressure and type of refuelling
system.
Close the fuel filler flap after
refuelling.

Fuel filler cap
Only use genuine fuel filler caps.
Diesel-engined vehicles have special fuel filler caps.
Fuel cut-off system
In the event of a collision of a certain
severity, the fuel system is cut-off and
the engine is switched off
automatically, for safety reasons.
Resetting the fuel cut-off system;
refer to "Fuel system messages"

Fuel consumption - CO
2-
Emissions
The fuel consumption (combined) of
the model Opel Combo is within a
range of 7.7 to 4.1 l/100 km.
Depending on country, the fuel
consumption is displayed in km/l. In
this case, the fuel consumption
(combined) of the model Opel Combo is within a range of 13.0 to 24.3 km/l.
The CO 2 emission (combined) is
within a range of 179 to 120 g/km.
For the values specific to your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle or other national registration
documents.
General information
The official fuel consumption and
specific CO 2 emission figures quoted
relate to the EU base model with
standard equipment.
Fuel consumption data and CO 2
emission data are determined
according to regulation R (EC)
No. 715/2007 (in the latest applicableversion), taking into consideration the
vehicle weight in running order, as specified by the regulation.
The figures are provided only for the
purpose of comparison between different vehicle variants and mustnot be taken as a guarantee for the
actual fuel consumption of a
particular vehicle.
Additional equipment may result in
slightly higher results than the stated
fuel consumption and CO 2 figures.
Furthermore, fuel consumption is dependent on personal driving style as well as road and traffic conditions.
Natural gas
The fuel consumption information
was obtained using reference fuel
G20 (methane proportion
99 - 100 mol%) under prescribed
driving conditions. When using
natural gas with a lower proportion of
methane, the fuel consumption can
differ from the specified values.
