Interior features
OThe outside temperature is extremely
low
OWhen the hybrid system is cool (for
example, after being left for a long time in low temperatures)
QWindshield defogger
When defogging the windshield using
the Remote Air Conditioning System, defogging may be insufficient due to the power being restricted more than during
normal air conditioning operation. Also, the outside of the windshield may fog up due to the outside temperature, humidity
or air conditioning set temperature.
QUsing the heater via the Remote Air Conditioning System
OWhen the outside temperature is low, heating may feel insufficient due to restricted operation of the air condi-
tioning.
OWhen the outside heat exchanger
becomes frosted over, heating perfor- mance may decline due to automati-cally switching to the frost removal
operation. ( P.406)
QSecurity feature
Any unlocked doors will be automatically locked when the system is operating.
The emergency flashers flash to indicate that the doors have been locked or the system has been turned off.
QConditions affecting operation

WARNING
QPrecautions for the Remote Air Conditioning System
ODo not use the system if people 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 dehy-dration or hypothermia, or could
result in death or serious injury.

ronment, signals from the wireless switch may transmit further than expected. Pay appropriate attention
to the vehicle’s surroundings and use the switch only when neces-sary.
ODo not operate “A/C” on the wire-less remote control if the hood is
open. The air conditioning may operate unintentionally and objects may be drawn into the electrical
cooling fan.
