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.

116 Driving and operation
Picture no: 11718s.tif
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
Picture no: 18528s.tif
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.
Picture no: 11629s.tif
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.

119

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.

120 Driving and operationSelf testing
When the engine is started and the vehicle
starts off, the system performs a self-check,
which may be audible.
Fault
Have cause of fault remedied by a
workshop. The system’s integrated self
diagnostics allow faults to be quickly
remedied.
Picture no: 12481s.tif
Hand brake Always apply handbrake firmly without
operating the release button, and apply as
firmly as possible on a downhill or uphill
slope.
To release the hand brake pull the lever up
slightly, press the ratchet knob, and fully
lower the lever.
In order to reduce the hand brake
operational forces, depress the foot brake
at the same time.
Brake assist When the brake pedal is rapidly and
forcefully depressed, the vehicle is
automatically braked with maximum brake
force amplification in order to obtain the
shortest possible braking distance during
full-on braking (brake assist).
Maintain steady pressure on the brake
pedal for as long as full-on braking is to
continue. When the brake pedal is
released, the maximum brake force
amplification is taken away.
9 Warning
If there is a fault in the ABS, the wheels
may be liable to lock due to braking that
is heavier than normal. The advantages
of ABS are no longer available. During
hard braking, the vehicle can no longer
be steered and may swerve.

Driving and operation
Wheels, tyres Suitable tyres or limitations 3191.
Tyres fitted in the factory are adapted to
the chassis and provide optimum driving
comfort and safety.
Changing tyre/wheel type
If tyres of a different size than those fitted
at the factory are used, it may be
necessary to reprogram the electronic
speedometer and make other vehicle
modifications.
After converting to a different tyre size,
have the adhesive label with tyre pressures
replaced. Fitting new tyres
Fit tyres in pairs or in sets, which is even
better. Ensure that tyres on one axle are
zthe same size,
zthe same design,
zthe same make,
zand have the same tread pattern.
Fit directional tyres such that they roll in the
direction of travel. The rolling direction is
indicated by a symbol (e.g. an arrow) on
the sidewall.
Tyres fitted opposing the rolling direction
(such as when changing a tyre) should be
refitted as soon as possible. This is the only
way to benefit fully from the design
properties of the tyre.
Pay attention to legal requirements when
disposing of tyres.
Picture no: 12117s.tif
Tyre pressure
Check tyre pressure at least every 14 days
and prior to any long journey; the tyres
should be checked when cold. Don’t forget
to check the spare 3.
Remove the valve cap key from the tank
flap and use it to unscrew the valve cap.
Tyre pressure 3191, 3192 and on the
adhesive label on the inside of the tank
flap.
The tyre pressure data is for cold tyres. It
applies to both summer and winter tyres.
9 Warning
Use of unsuitable tyres or wheels may
lead to accidents and render the vehicle
unroadworthy.

122 Driving and operationAlways inflate the spare wheel 3 to the
pressure specified for full load.
Do not reduce tyre pressure when the tyres
are warm. Otherwise the pressure may
drop below the permissible minimum when
the tyres cool down.
After having checked the tyre pressure,
tighten the valve caps using the valve cap
key.
Incorrect inflation pressures will impair
safety, vehicle handling, comfort and fuel
economy and will increase tyre wear.
Picture no: 9358t.tif Picture no: 15941s.tif
Tyre condition, wheel condition
Drive over edges slowly and at right angles
if possible. Driving over sharp edges can
cause tyre and wheel damage. Do not trap
tyres on the kerb when parking.
Regularly check the wheels for damage.
Seek the assistance of a workshop in the
event of damage or unusual wear.
9 Warning
If the pressure is too low, this can result
in considerable tyre warm-up and
internal damage, leading to tread
separation and even to tyre blow-out at
high speeds.
