2017.5 OPEL ANTARA cooling

Climate control121Active carbon filter
In addition to the particle filter the active carbon filter reduces odours.
Air conditioning regularoperation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
week, irrespective of the weather and time of year. Operation with cooling is
not possible when outside
temperature is too low.
ServiceFor optimal cooling performance, it is
recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts● cleaning of condenser and evaporator drainage
● performance check
Note
Refrigerant R-134a contains
fluorinated greenhouse gases.

Driving and operating127The engine will be switched off whilethe ignition stays on.
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
During an Autostop, the heating, power steering and brake
performance will be maintained.
Air conditioning system may or may
not inhibit the stop-start system
according to the cooling performance.
Caution
The steering assist can be
reduced during an Autostop.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled.
● The stop-start system is not manually deactivated
● the bonnet is fully closed
● the driver's door is closed or the driver's seat belt is fastened
● the vehicle battery is sufficiently charged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high or low
● the engine exhaust temperature is not too high, e.g. after driving
with high engine load
● the ambient temperature is not too low
● the defrosting function is not activated
● the climate control system does not inhibit an engine stop
● the brake vacuum is sufficient● the self-cleaning function of the diesel particle filter is not active
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
Certain settings of the climate control
system may inhibit an Autostop. See
"Climate control" chapter for more
details 3 116.
Immediately after motorway driving
an Autostop may be inhibited.

Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the driver Depress the clutch pedal to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.

142Driving and operatingEnsure the radiator core and the areabetween the radiator and intercooler/
oil cooler (where installed) is cleaned, to maintain proper cooling air flow.Check the radiator and cooler cores
for blockage (sand, silt etc.).
Check the tyre treads.
Clean and check the mechanical
parts of the vehicle, particularly the
following areas:
● Driveshafts, including sealing bellows
● Front brake calipers, pads and discs
● Front suspension
● Clutch fork sealing bellows
● Rear brake calipers, pads and discs
● Rear suspension
● Fuel tank and underguard
● Breathers, axles and fuel tank
● Load sensing valve
● Transfer box and underguard
● Engine oil pan and underguardObserve the following: ● Do not spray high-pressure water
directly at the vehicle seals
● The wheels must be removed to clean all mud and stones from the
brake calipers and to check
brake pad wear
● The areas on the upper side of the underguards must be clearedof stones, to prevent damage to
the engine oil pan and the fuel
tankBrakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
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. It is especially important to bear this in mind when being towed.
Control indicator R 3 85.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.

152Driving and operatingconsumption and CO2 figures.
Furthermore, fuel consumption is dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
The coupling ball bar is kept in a bag,
fastened with a strap and is stowed
below the floor cover in the load
compartment.
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.
Control indicator á illuminates in the
instrument cluster when a trailer is
connected to the vehicle 3 91.
Driving characteristics and towing tips
In the case of trailers with brakes,
attach the break-away stopping cable
to the eye - not to the coupling ball
bar.
If no eye is available, loop cable
around coupling ball bar. Ensure
cable is crossed under the verticalcoupling socket to ensure the trailer
nose cannot drop to the ground if it
becomes separated from the trailer
hitch. Do not allow the cable to drag
along the ground and always allow
enough slack to permit full turning.
Follow the instructions supplied with
the towing equipment.
Before attaching a trailer, lubricate
the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements. For trailers with
low driving stability, the use of a
friction-type stabiliser is strongly
recommended.
Do not drive faster than 80 km/h, even in countries where higher speeds are
permitted. When driving uphill, do not drive faster than 30 km/h in 1st gear,or 50 km/h in 2nd gear.
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.

viscosity 3 202.
Fit the cap on straight and tighten it.
Control indicators for engine oil
pressure I 3 88, engine oil life ¢
3 89, and low engine oil S 3 89.
Once the engine oil has been
changed, the engine oil life monitor needs to be reset. Seek the
assistance of a workshop.
Engine coolant
The coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant provides frost protection down to
approx. -37 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be between the
MIN and MAX marks. Top up if the
level is low.9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.

Vehicle care187Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Tyre chains
Tyre chains are only permitted on the
front wheels.
They must be fitted to the tyres
symmetrically in order to achieve a
concentric fit.
9 Warning
Damage may lead to tyre blowout.
Special snow chains are only
permitted when they are designed
with a rotating chain belt on the tyre
tread, no chain links on the wheel
inboard sides and the chains add no
more than 12 mm to the tyre tread.
For further information regarding
correct snow chain usage for the tyre
size, contact a specialised vehicle
parts dealer or snow chain
manufacture. Tyre chains are only
permitted on tyres of size
235/60 R17 and 235/55 R18.General
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit
Minor damage to the tyre tread or
sidewall can be repaired with the tyre
repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is at the tyre's sidewall near the rim
cannot be repaired with the tyre repair kit.
In vehicles with a tyre repair kit, there may not be a jack and vehicle tool kit.
