Air Conditioning System
●When the outside temperature is
low, heating may feel insufficient
due to restricted operation of the
air conditioning.
●When the outside heat exchanger
becomes frosted over, heating
performance may decline due to
automatically switching to the frost
removal operation. ( P.424)

are in the vehicle.
Even when the system is in use,
the internal temperature may
still reach a high or low level
due to features such as the
automatic shut-off. Children and
pets left inside the vehicle may
suffer heatstroke dehydration or
hypothermia or could result in
death or serious injury.
●Depending on the surrounding
environment, signals from the
wireless switch may transmit
further than e xpected. Pay
appropriate attention to the
vehicle’s surroundings and use
the switch only when neces-
sary.
●Do not operate “A/C” on the
wireless remote control if the
hood is open. The Remote Air
Conditioning System may oper-
ate unintentionally and objects
may be drawn into the electrical
cooling fan.

Maintenance and care
The 12-volt battery is located in
the right-hand side of luggage
compartment.
■Before recharging
When recharging, the 12-volt bat-
tery produces hydrogen gas which
is flammable and explosive. There-
fore, observe the following precau-
tions before recharging:
●If recharging with the 12-volt bat-
tery installed on the vehicle, be
sure to disconnect the ground
cable.
●Make sure the power switch on
the charger is off when connecting
and disconnecting the charger
cables to the 12-volt battery.
■After recharging/reconnecting
the 12-volt battery
●Unlocking the doors using the
smart key system may not be pos-
sible immediately after reconnect-
ing the 12-volt battery. If this
happens, use the wireless remote
control or the mechanical key to
lock/unlock the doors.
●Start the hybrid system with the
power switch in ACC. The hybrid
system may not start with the
power switch turned off. How-
ever, the hybrid system will oper-
ate normally from the second attempt.
●The power switch mode is
recorded by the vehicle. If the 12-
volt battery is reconnected, the
vehicle will return the power
switch mode to the status it was in
before the 1
2-volt battery was dis-
connected. Make sure to turn off
the power switch before discon-
nect the 12-volt battery. Take
extra care when connecting the
12-volt battery if the power switch
mode prior to discharge is
unknown.
