engine OPEL COMBO E 2020 Repair Manual

206Driving and operatingCaution
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 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.
In certain countries, the use of a
particular fuel, e.g. a specific octane
rating, may be required to ensure
proper engine operation.
Fuel for diesel engines
The diesel engines are compatible
with bio-fuels that conform to current and future European standards and
and can be obtained from filling
stations:
Diesel fuel that meets standard
EN590 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 7 % Fatty Acid Methyl Ester)
Diesel fuel that meets standard
EN16734 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 10% Fatty Acid
Methyl Ester)
Paraffinic diesel fuel that meets
standard EN15940 mixed with a
biofuel that meets standard
EN14214 (possibly containing up to 7% Fatty Acid Methyl Ester).
The use of B20 or B30 fuel meetingstandard EN16709 is possible in your
diesel engines. However, this use,
even occasional, requires strict

Driving and operating207application of the special servicingconditions referred to as "Arduous
conditions".
For more information, contact a
dealer or a qualified workshop.Caution
The use of any other type of (bio)
fuel (vegetable or animal oils, pure
or diluted, domestic fuel etc.) is
strictly prohibited (risk of damage
to the engine and fuel system).
Note
The only diesel additives authorised for use are those that meet the
B715000 standard.
Vehicles with diesel engine operating
in Ecuador require the additive
DLP 32-600 to avoid damage of the
injection system. This additive can
only be purchased at Opel dealers.
The additive has to be poured into the
tank before refilling Diesel. For each
50 litres of Diesel refilled, 30 millilitres of additive have to be added. To dose
the additive, use the cap of the
additive can. The cap allows a dose
of 30 millilitres.
Low temperature operation At temperatures below 0 °C, somediesel products with biodiesel blendsmay 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.
Refuelling9 Danger
Before refuelling, switch off
ignition and any external heaters
with combustion chambers.
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.
A label with symbols at the fuel filler
flap is indicating the allowed fuel
types. In Europe the pump nozzles of the filling stations are marked with
these symbols. Refuel only the
allowed fuel type.
Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at left rear
side of vehicle.

208Driving and operating
If the vehicle is equipped with an
electronic key system, the fuel filler
flap can only be opened if the vehicle
is unlocked. Depending on the
version, release the fuel filler flap by
pushing the flap or pulling at the right bottom corner.
Petrol and diesel refuellingDepending on the version, place the
key in the lock and unlock the cap.
To open, turn the cap slowly
anticlockwise.The fuel filler cap can be attached to
the hook on the fuel filler flap.
Place the nozzle in straight position to
the filler neck and press with slight
force to insert.
To refuel, switch on pump nozzle.
After the 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, turn the fuel filler cap
clockwise until it clicks.
Close the flap and allow it to engage.
Fuel filler cap
Only use genuine fuel filler caps.
Diesel-engined vehicles have special fuel filler caps.

Driving and operating209Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
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.
The bulb outage detection function for trailer brake light cannot detect a
partial bulb outage e.g. in case of four
bulbs with a power of 5 W each, the
function only detects lamp outage
when only a single 5 W lamp remains
or none remain.
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 to have it on hand if needed.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.
During trailer towing do not exceed a
speed of 80 km/h. A maximum speed
of 100 km/h is only appropriate if an
oscillation damper is used and the
permissible gross trailer weight does
not exceed the vehicle’s curb weight.
For trailers with low driving stability
and caravan trailers, the use of an
oscillation damper is strongly
recommended.
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 3 266.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 inclines up
to 12%.
The permissible trailer load applies
up to the specified incline and at 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 altitude. The gross train weight does not have to be reduced when driving on roads with
slight inclines (less than 8%, e.g.
motorways).

Driving and operating2134. Connect the trailer plug to thesocket and attach the breakaway
stopping cable to the eye on the
carrier.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle / trailer combination is
selectively braked until the snaking
ceases. While system is working keep steering wheel as still as possible.
Trailer stability assist is a function of
the Electronic Stability Control 3 166.
