cooling OPEL KARL 2019 Owner's Manual

In brief19Parking9Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake. Activate the manual
parking brake without pressing the release button. Apply as
firmly as possible on a downhill slope or uphill slope. Depress
brake pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear before removing the ignition key. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear
before removing the ignition
key. Turn the front wheels
towards the kerb.
● Close the windows and the sunroof.
● Remove the ignition key from the ignition switch. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
● Lock the vehicle by pressing e on
the radio remote control.
Activate the anti-theft alarm
system 3 27.
● The engine cooling fans may run
after the engine has been
switched off 3 128.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low
load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.

functional when the engine is running
and climate control fan is switched on.
Press A/C again to switch off cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
Activated cooling may inhibit
Autostops.

Direct the flow of air by tilting the slats.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.

Climate control103Fixed air ventsAdditional air vents are located
beneath the windscreen and door windows and in the foot wells.Maintenance
Air intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when the
outside temperature is too low.
Service For 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
