2010 OPEL COMBO ignition

114 Driving and operationIf the natural gas tank is then not refilled,
petrol operation must be manually
selected the next time the engine is started.
This is necessary in order to prevent
damage to the catalytic converter
(overheating due to irregular fuel supply).
If the switch is pressed several times within
a brief period of time, a changeover
inhibitor is activated. The engine continues
with the current type of fuel. The inhibitor
remains active until the ignition is switched
off.
Minor power and torque losses are to
be expected during petrol operation,
therefore adjust driving style (e.g.
overtaking) and vehicle load (e.g. through
trailer load) accordingly.
Every 6 months, run the petrol tank down
to the reserve zone before refuelling. This is
necessary for petrol operation to obtain
the required system functionality and fuel
quality.Note:
Refuel and operate only w i t h f u e l o f a t l e a s t
95 octane (RON). Upon accidental
refuelling with petrol of an
octane rating (RON) less than 95, avoid
driving with fuel load (e.g. heavy
acceleration, full throttle), allow the tank to
reach the reserve zone and refuel with the
correct petrol.
In order to prevent corrosion in the tank,
please refuel the vehicle to the maximum
level at regular intervals.

Catalytic converter, engine
exhaust Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gas, such as carbon monoxide
(CO), hydrocarbons, (CH) and nitrous
oxide (NO
x).
Fuel grades other than those listed on
3110, 184 (e. g. LRP = Lead Replacement
Petrol or leaded fuel) could damage the
catalytic converter or electronic
components.
Caution
Damage to the catalytic converter or the
vehicle may result if the following points
are not observed.

115
Driving and operation
zIn the event of misfiring, uneven engine
running, a clear reduction in engine
performance or other unusual problems,
have the cause of the fault rectified by a
workshop as soon as possible. In an
emergency, driving can be continued for
a short period, keeping vehicle speed
and engine speed low.
zIf unburnt fuel enters the catalytic
converter of a petrol engine, this may
result in overheating and irreparable
damage to the catalytic converter.
You should therefore avoid
unnecessarily long use of the starter
when starting off, running the tank dry
and starting the engine by pushing or
towing.

Controlling exhaust emission
Design measures, primarily in the fuel
injection system and ignition system zones
in combination with the catalytic converter,
the amount of hazardous substances in the
exhaust emissions, such as carbon
monoxide (CO), hydrocarbons (CH) and
nitrogen oxides (NO
x), are reduced to a
minimum.
Picture no: 11717s.tif
Exhaust gas control indicator
Z
Illuminates when the ignition is switched on
and during the start attempt. Goes off
shortly after the engine starts running.
Illumination whilst the engine is running
indicates a fault in the emission control
system. The permissible emission limits
may be exceeded. Contact a workshop for
assistance immediately.
Illumination with the engine running
indicates a fault that can cause damage to
the catalytic converter. It is possible to
continue driving without causing damage
by slowing down until the flashing stops
and the control indicator illuminates.
Contact a workshop for assistance
immediately.

Control indicator
A
for engine electronics

Illuminates for a few seconds when ignition
is switched on.
If it comes on when the engine is running,
there is a fault in the engine or transmission
electronics. The electronics switch to the
emergency running programme, fuel
consumption may increase and the
driveability of the vehicle may be affected.
In some cases the fault can be remedied by
switching the engine off and starting it
again. If the control indicator continues to
illuminate whilst the engine is running,
contact a workshop for assistance in
remedying the cause of the fault. If it illuminates briefly, but does not recur, it
is of no significance.
If A illuminates, there may be water in the
diesel fuel filter 3. Have the fuel filter
checked for water residue by a workshop
3177.
I f i t f l a s h e s a f t e r t h e i g n i t i o n i s s w i t c h e d o n ,
there is a fault in the immobiliser system.
The engine cannot be started 321.
Engine exhaust Diesel particle filter 3
The diesel particle filter system filters
harmful soot particles out of the exhaust
gases. The system includes a self-cleaning
function that run automatically during
driving. The filter is cleaned by burning off
the soot particles at high temperature. This
process takes place automatically under
set driving conditions and may take up to
25 minutes. Fuel consumption may be
higher during this period. The emission of
smells and smoke during this process is
normal.
9 Warning
Engine exhaust gases contain poisonous
carbon monoxide, which is colourless
and odourless and could be fatal if
inhaled.
If exhaust gases penetrate the vehicle,
open windows and contact a workshop
for assistance.
Avoid driving with an open tailgate.
Otherwise, exhaust gases could get into
the interior.

117
Driving and operation

Under certain driving conditions, e.g. short
distances, the system cannot clean itself
automatically.
If the filter requires cleaning and previous
driving conditions did not enable
automatic cleaning, control indicator !
flashes. Continue driving, keeping engine
speed above 2000 rpm
-1. Shift down if
necessary. Diesel particle filter cleaning is
then initiated.
Picture no: 18535s.tif
We recommend that you do not stop your
journey or switch off the ignition during
cleaning. Cleaning takes place most
quickly at high engine speeds and high
loads.
Picture no: 18536s.tif
The control indicator
! goes off as soon as
the self-cleaning operation is complete.

118 Driving and operationMaintenance
Have all maintenance work carried out at
the specified intervals. We recommend
that you entrust this work to your Opel
Partner, who has proper equipment and
trained personnel available. Electronic
testing systems permit rapid diagnosis and
remedy of faults. This way you can be
certain that all components of the vehicle’s
electrical, injection and ignition systems
operate correctly, that your vehicle has a
low level of pollutant emission and that the
catalytic converter system will have a long
service life.
You are thereby making an important
contribution towards keeping the air clean
and compliance with emissions legislation.
Checking and adjustment of the fuel-
injection and ignition systems is part of the
scope of inspection. For this reason you
should have all maintenance work carried
out at the intervals specified in your Service
and Warranty Booklet.

Hydraulic brake system The foot brake comprises two independent
brake circuits.
If a brake circuit fails, the vehicle can still be
braked using the other brake circuit.
However, the brake pedal must be
depressed a considerable way before any
braking effect occurs, and much more
force is required. The braking distance is
longer. Contact a workshop for assistance
before continuing to drive. To ensure the full pedal travel can be
utilised, especially in case of a fault in one
of the brake circuits, there must be no mats
in the vicinity of the pedals 3107.
When the engine is not running, the
support of the brake servo unit disappears
once the brake pedal has been depressed
once or twice. Braking effect is not
reduced, but braking requires significantly
greater force. This is especially important
to bear in mind when towing.
The brake fluid level should be checked
regularly. If the brake fluid level is too low
and the hand brake is not applied, control
indicator R on the instrument panel lights
up 369.

Brake system control indicator R
The control indicator illuminates when the
ignition is switched on if the hand brake is
applied or if the brake or clutch fluid level is
too low. Brake fluid 3179. For vehicles with manual transmission
automated 3, the control indicator flashes
for a few seconds when the ignition is
turned off if the hand brake is not applied.
Anti-lock Braking System
(ABS
u)3
ABS prevents the wheels from locking.
ABS starts to regulate brake pressure as
soon as a wheel shows a tendency to lock.
The vehicle remains steerable, even during
hard braking.
ABS control is made apparent though a
pulse in the brake pedal and the noise of
the regulation process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the
pedal is pulsating. Do not reduce the
pressure on the pedal.
Picture no: 12147s.tif
Control indicator u for ABS
It illuminates for a few seconds when
ignition is switched on. Once the control
indicator goes out, the system is ready for
operation.
If the control indicator does not go out
after a few seconds, or if it illuminates while
driving, there is a fault in the ABS. The
brake system remains operational without
ABS regulation.
9 Warning
If the control indicator illuminates when
the handbrake is released, stop driving
immediately. Contact a workshop for
assistance.

Screw in the towing eye anticlockwise as far
as it will go until it stops in a horizontal
position.
Attach a tow rope 3 – or better still a tow
rod3 – to the eye.
The towing eye is only to be used for
towing and not for vehicle recovery. Switch on ignition to release steering
column lock and to permit operation of
brake lamps, horn and windscreen wipers.
Manual transmission in neutral; manual
transmission automated 3 in N. When the engine is not running,
considerably more force is needed to brake
and steer.
To prevent the entry of exhaust fumes from
the towing vehicle, switch on the air
recirculation 3 and close the windows.
Contact a workshop for assistance.
If the automatic clutch has been manually
disengaged on a vehicle with manual
transmission automated 3 towing is not
permitted 3105. In this case, contact a
workshop for assistance immediately.
After towing, unscrew the towing eye
clockwise and refit the cover.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can damage
the vehicle.
