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.

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.

Lift the safety catch and open the bonnet.
Dirt or snow on the bonnet may drop onto
the windscreen when the bonnet is opened
and block the air intake. Air intake 399.
Picture no: 15123s.tif
Secure the bonnet support. Before closing
the bonnet, press the support into the
holder.
Lower the bonnet and allow it to drop into
the catch. Check that the bonnet is
engaged.
Starting the engine with jump
leads
3
Do not start by quick charger or by pushing
or towing.
A vehicle with a discharged battery can be
started using jump leads and the battery of
another vehicle.
9 Warning
Starting the engine with jump leads must
be carried out with the utmost caution.
Any deviation from the following
instruction may lead to injury or damage
due to the explosion of the batteries and
to damage of the electrics in both
vehicles.

Underbody
Some areas of the vehicle underbody have
a PVC undercoating while other critical
areas have a durable protective wax
coating.
After the underbody is washed, check the
underbody and have more protective wax
applied if necessary.
Bitumen/rubber materials could damage
the PVC coating. Have underbody work
carried out by a workshop.
Before and after winter, wash the
underbody and have the protective wax
coating checked. Natural gas system3
When cleaning the engine or underbody
with a steam jet or high pressure jet
cleaner, do not aim the jet at components
of the natural gas system. In particular, the
natural gas tanks and the pressure valves
at the vehicle underbody and bulkhead in
the engine compartment must be
protected from the pressurised spray.
In addition, these components must not be
treated with chemical cleaners or waxes.
Have natural gas system components
cleaned by a workshop that is authorised
to maintain natural gas vehicles.
Towing equipment
Do not clean the coupling ball bar with a
steam-jet or high-pressure jet cleaner.

172 Opel Service, maintenanceEngine oil
Engine oil is identified by its grade and
viscosity. When choosing which engine oil
to use, grade is more important than
viscosity.
The new GM-Dexos 2 engine oil grade is
currently the highest grade. If it is not
available, the other engine oil grades that
are listed must be used.
Engine oil grade for the European
service plan
Engine oil grade for the International
service planTopping up engine oil
Oil from different manufacturers and of
different brands can be mixed providing
they meet the specified engine oil criteria
(grade and viscosity).
Not every engine oil available on the
market satisfies the quality requirements,
so always check whether the required
specifications and classifications are
written on the container.
If an engine oil of the required grade is not
available, a maximum of 1 litre of
ACEA A3/B4 or A3/B3 oil may be used (just
once between oil changes). The viscosity
must comply with the requirements.
Using category ACEA A1/B1 and A5/B5
engine oil is expressly forbidden because it
can cause long-term damage to the engine
under certain operating conditions.Engine oil additives
The use of engine oil additives can cause
damage and void the warranty.
Engine oil viscosity
Only use engine oils of viscosity 0W-30,
0W-40, 5W-30 or 5W-40.
The SAE viscosity classification defines the
fluidity of the oil: the oil is more viscous
when cold than when hot.
Multigrade oil is indicated by two numbers.
The first number followed by a W gives the
viscosity at low temperature and the
second number gives the viscosity at high
temperature. GM-Dexos 2 = Petrol and
diesel engines
GM-LL-A-025 = Petrol engines
GM-LL-B-025 = Diesel engines
GM-Dexos 2 = Petrol and
diesel engines
GM-LL-A-025 = Petrol engines
GM-LL-B-025 = Diesel engines
ACEA-A3 = Petrol engines
ACEA-B4 = Diesel engines

Performing work To avoid injury from moving parts and
cables conducting ignition voltage, only
carry out engine compartment checks
(e. g. checking brake fluid or engine oil
level) when the ignition is switched off.
Picture no: 11671s.tif
To aid identification, the caps used when
topping up engine oil, coolant and washer
fluid as well as the oil dipstick are coloured
yellow.
9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start operating
even if the ignition is off.
9 Warning
The ignition system 3 and Xenon
headlamps 3 use extremely high
voltage. Do not touch.
