2765-3. Using the air conditioning system
and the fan is operating, turning automatic
mode on will activate the dehumidification
function. The next time the dehumidification
function is turned off, the automatic mode
for switching between outside air and recir-
culated air modes is canceled.
This function automatically controls the
air conditioning airflow so that priority
is given to the front seats. When the
front passenger seat is not occupied,
airflow may switch to only the driver’s
seat. Unnecessary air conditioning is
suppressed, contributing to increased
fuel efficiency.
Front seat concentrated airflow mode
operates in the following situations.
No passengers are detected in the rear seats
 The windshield defogger is not
operating
While operating, illuminates.
QManually turning front seat con-
centrated airflow mode on/off

and switch the airflow.
 Indicator illuminated: Airflow to the
front seats only
 Indicator off: Airflow to all the seats
QOperation of automatic airflow control
OIn order to maintain a comfortable inte-
rior, airflow may be directed to seats
without passengers immediately after the
hybrid system is started and at other
times depending on the outside tempera-
ture.
OAfter the hybrid system is started, if pas-
sengers move around inside or enter/exit
the vehicle, the system cannot accurately
detect the presence of passengers and
automatic airflow control will not oper-
ate.
QOperation of manual airflow control

When trouble arises
WARNING
QIf a blowout or sudden air leakage
should occur
The tire pressure warning system may
not activate immediately.
QMaintenance of the tires
Each tire, including the spare (if pro-
vided), should be checked monthly when
cold and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire infla-
tion pressure label (tire and load
information label). (If your vehicle has
tires of a different size than the size indi-
cated on the vehicle placard or tire infla-
tion pressure label [tire and load
information label], you should determine
the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS-tire pressure
warning system) that illuminates a low
tire pressure telltale (tire pressure warn-
ing light) when one or more of your tires
is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale
(tire pressure warning light) illuminates,
you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire
to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect
the vehicle’s handling and stopping abil-
ity.
Please note that the TPMS (tire pressure
warning system) is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain correct
tire pressure, even if under-inflation has
not reached the level to trigger illumina-
tion of the TPMS low tire pressure telltale
(tire pressure warning light).
Your vehicle has also been equipped
with a TPMS (tire pressure warning sys-
tem) malfunction in dicator to indicate
when the system is not operating prop-
erly. The TPMS (tire pressure warning
system) malfunction indicator is com-
bined with the low tire pressure telltale
(tire pressure warning light). When the
system detects a malfunction, the telltale
will flash for approximately one minute
and then remain continuously illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal
low tire pressure as intended.
TPMS (tire pressure warning system)
malfunctions may occur for a variety of
reasons, including th e installation of
replacement or alternate tires or wheels
on the vehicle that prevent the TPMS
(tire pressure warning system) from
functioning properly. Always check the
TPMS (tire pressure warning system)
malfunction telltale after replacing one
or more tires or wheels on your vehicle
to ensure that the replacement or alter-
nate tires and wheels allow the TPMS
(tire pressure warning system) to con-
tinue to function properly.
NOTICE
QTo ensure the tire pressure warning
system operates properly
Do not install tires wi th different specifi-
cations or makers, as the tire pressure
warning system may not operate prop-
erly.
