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

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.

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.

Driving and operating139Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Vehicles with natural gas engine may
require special towing equipment.
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.
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.
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 caravan trailers with a permitted
gross vehicle weight of more than
1300 kg the use of a stabiliser is
strongly recommended when driving
above 80 km/h.
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 3 191.
Trailer towing
Trailer loads The permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12%.
The permitted trailer load applies up
to the specified incline and up to an
altitude of 1000 metres above sea
level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 metres of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than 8%, e.g. motorways).
The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 181.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
