2018 OPEL KARL air conditioning

Climate control105Press 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 might inhibit
Autostops.
Stop-start system 3 111.
Air recirculation mode 4
Press 4 to activate air recirculation
mode. The LED in the button
illuminates to indicate activation.
Press 4 again to deactivate air
recirculation mode.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling, the
air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen may mist
up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper.
Maximum cooling Briefly open the windows so that hotair can disperse quickly.
● Switch on cooling A/C.
● Switch on Air recirculation system 4.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Set air distribution control to M.
● Open all vents.
Air vents
Adjustable air vents
At least one air vent must be open
while the cooling is on.
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.

106Climate controlFixed air vents
Additional 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.
Pollen filter The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
The filter should be replaced as part
of routine scheduled maintenance.Caution
More frequent maintenance of the passenger compartment air filter is
required if the driving
circumstances are dusty roads, air pollution areas, and frequent
unpaved roads.
The filter efficiency is decreased
and the bronchus is badly
affected.
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.

Driving and operating113● The brake vacuum is sufficient.
● The vehicle was driven at least at
walking speed 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 further information 3 102.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 109.
Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Power saving measures
During an Autostop, several electrical
features, e.g., the rear window
heating, are disabled or switched into
a power saving mode. The fan speed of the climate control system is
reduced to save power.Restart of the engine by the driverVehicles with manual transmission
Depress the clutch pedal to restart the
engine.
If the selector lever is shifted out of
neutral before depressing the clutch
pedal first, control indicator -
illuminates or is shown as a symbol in the Driver Information Centre.
Control indicator - 3 73.Vehicles with manual transmission
automated
Release the brake pedal or move
selector lever out of D to restart the
engine.
Restart of the engine by the stop-
start system
The selector lever must be in neutral
to enable an automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
● The stop-start system is manually deactivated.
● The bonnet is opened.
● The driver's seat belt is unfastened and the driver's door
is opened.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
● The brake vacuum is not sufficient.
● The vehicle is driven at least at walking speed.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
