11-5Service and maintenance
Additional servicing
Additional operations ⊕
Additional work is work that is not
required every service but can be
performed in conjunction with a
regular service.
Time allowances for such work are
not included in the scope of regular
services and will be charged for
additionally. It is more economic if
these operations are performed as
part of a scheduled service than
having them performed separately.
Severe operating conditions o
Operating conditions are classified as
severe when one or more of the
following occurs frequently:
„cold starts,
„stop and go,
„trailer/caravan towing,
„gradients and/or high altitudes,
„poor road surfaces,
„sand and dust,
„extreme temperature fluctuations. Police vehicles, taxis and driving
school vehicles are also classified as
operating under severe conditions.
Under severe operating conditions, it
may be necessary to have certain
scheduled service work done more
frequently than the scheduled
intervals.
For example, if fuel is used that does
not comply with required standards,
the fuel filter may need more frequent
draining or replacement and it may
also be necessary to change other
components more often (e.g. spark
plugs).
It is recommended to seek technical
advice on the servicing requirements
dependent on the specific operating
conditions of your vehicle.
Recommended fluids
and lubricants
Only use products that have been
tested and approved. Damage
resulting from the use of non-
approved materials will not be
covered by the warranty.
Checking and topping up fluids
3 10-3.
9 Warning
Operating materials are
hazardous and must be handled
with the appropriate level of care.
If consumed, seek medical
attention immediately. Do not
inhale fumes and avoid skin
contact. Keep out of reach of
children. Do not allow operating
materials to contaminate the
sewage system, surface water,
ground water or soil. Dispose of
empty containers properly.
Always bear in mind that
operating materials are
hazardous to your health.

11-6 Service and maintenance
Engine oil
Engine oil is identified by its quality
and also its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use.
Engine oil quality
Opel engine oil meets classifications
GM-LL-A-025 and GM-LL-B-025 and
is therefore suitable for both petrol
and diesel engines.
Topping up engine oil
Oils of different manufacturers and
brands can be mixed as long as you
comply with the specified engine oil
criteria (quality and viscosity).Not every engine oil available on the
market meets the quality
requirements, always check the
required specification and rating is
marked on the container.
If engine oil of the required quality is
not available, a maximum of 1 litre of
ACEA A3/B4 or A3/B3 grade may be
used (only once between each oil
change). The viscosity should be of
the correct rating.
Use of ACEA A1/B1 and A5/B5
engine oil is expressly forbidden,
since they can cause long-term
engine damage under certain
operating conditions.
Engine oil additives
The use of engine oil additives could
cause damage and invalidate the
warranty.
Engine oil viscosity
Diesel engines:
SAE 0W-30, 0W-40, 5W-30 or 5W-40
Petrol engines:
SAE 5W-30The SAE viscosity rating defines the
ability of an oil to flow. When cold, oil
is more viscous than when hot.
Multigrade oil is indicated by two
figures. The first figure, followed by a
W, indicates low temperature
viscosity and the second figure the
high temperature viscosity.
Coolant and antifreeze
Use antifreeze of recommended
specification. GM-LL-A-025: Petrol engines

11-7Service and maintenance
The system is factory-filled with
coolant designed for frost protection
down to approx. -28 °C. This
concentration should be maintained
all year-round.
Coolant additives intended to give
additional corrosion protection or seal
against minor leaks can cause
function problems. Liability for
consequences resulting from the use
of coolant additives will be rejected.
Brake and clutch fluid
Only use DOT4 brake fluid.
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.
Brake fluid should be stored in a
sealed container to avoid water
absorption. Ensure it does not become
contaminated with fluids containing
mineral oil (oil, petrol, cleaner) as this
can damage the seals and sleeves of
the brake system.Transmission fluid
Use fluid meeting specification
Grade: API GL-4
Viscosity: 75W-85 or 75W-90.
Automatic transmission fluid
Use fluid meeting specification
ATF3309.
9 Warning
Brake fluid is poisonous!
Caution
Due to its corrosive nature, it must
not come in contact with the
paintwork. Flush any escaped
brake fluid with plenty of water.

For example, if the front axle load is
being fully utilized, the rear axle can
only bear a load that is equal to the
Gross Vehicle Weight minus the front
axle load.
The visible VIN may also be stamped
on a plate and affixed to the
instrument panel on the driver’s side,
visible through the windscreen.
Depending on version, the VIN may
be affixed to the cowl panel in the
engine compartment above the
windscreen washer fluid reservoir,
visible with the bonnet open.Engine number
