position P.
If all the operating requirements
have been met, the engine is shut
down.
The air flow rate of the air condi-
tioning system is reduced when the
engine is not running.
■General
The engine is not shut down auto-
matically in the following situations:On steep downward gradients.
Brake not pressed strongly
enough.
High outside temperature and
operation of the automatic air
conditioning.
Interior not heated or cooled to
the desired temperature.
Where there is a risk of conden-
sation when the automatic air
conditioning is switched on.
Engine or other parts not at oper-
ating temperature.
Engine cooling is required.
Sharp steering angle or steering
operation.

interior when the cooling function
is switched on.
Very low temperature in the inte-
rior when the heating is switched
on.

WARNING
When using the air conditioning sys-
tem, seat heaters, etc. for a long
period of time, make sure that no
body parts are kept near the air out-
lets or in direct contact with the seat,
as doing so may lead to minor burns
or chill burns. If you feel unusual while
using the air conditioning system or
seat heaters, stop use or change the
setting immediately.

Interior air is cooled and dried, then
reheated to suit the temperature

The cooling function is switched on
when the engine is running.
Depending on the weather condi-
tions, the windscreen and side win-
dows may mist over for a short time
when the drive-ready state has
been switched on.
The cooling function is switched on
automatically in the AUTO pro-
gramme.
When the automatic air condition-
ing is in operation, condensation
develops and exits underneath the
vehicle.
When drive-ready state is switched
on, the system is set to lowest tem-
perature, optimum air flow and
recirculated-air mode.
The function is available at an out-
side temperature above approxi-
mately 0°C/32°F and when
drive-ready state is switched on.The LED is illuminated when the
system is switched on.
The air flows from the side nozzles
for the upper body area. Therefore
open the side nozzles.
The air flow can be adapted when
the programme is active.
The AUTO programme cools, venti-
lates or heats the interior automati-
cally.
It does this by automatically regu-
lating the air flow, air distribution
and temperature depending on the
interior temperature and the
selected temperature setting.
The LED is illuminated when the
AUTO programme is switched on.
Depending on the selected temper-
ature and external influences, the

The cooling function, see page 251,
is switched on automatically in the
AUTO programme.
The AUTO programme is automati-
cally switched off when the air dis-
tribution is set manually.
If the air outside the vehicle has an
unpleasant odour or contains pol-
lutants, the supply to the interior of
the vehicle can be shut off. The air
inside the vehicle is then recircu-
lated.
The LED is illuminated when the
recirculated-air mode is switched
on.
When the left LED is illuminated:
Automatic recirculated air mode
If the pollution sensor detects pollutants
in the outside air, the air mode is auto-
matically changed from outside air
mode to recirculated air mode.
When the right LED is illuminated:
Recirculated air mode
The air in the cabin is continuously
recirculated.
The recirculated-air mode automat-ically switches off after a given time
depending on the ambient condi-
tions, to avoid condensation.
Continuous recirculated-air mode
deteriorates the air quality in the
interior and condensation on the
windows increases.
If there is condensation, shut down
recirculated-air mode or remove the
condensation, see page 254.
The air flow for air conditioning can
be set manually.
To be able to adjust the air flow
manually, first switch off the AUTO
programme.
Selected air flow is shown on the
climate display.
In order to protect the battery the

Do not align the air flow directly

The independent ventilation allows
the temperature of the interior to be
adjusted before the journey starts.
Depending on the set temperature
and ambient temperature, the inte-
rior is ventilated or heated using
any available residual heat from the
engine.
The system can be switched on
and off directly or for a preselected
departure time.
The system can also be used via
the Toyota Supra Connect app.
The switch-on time is calculated
based on the outside temperature.
The system will switch on in good
time before the preselected depar-
ture time.
