Remote Air Conditioning System
The Remote Air Conditioning System uses electrical energy stored
in the hybrid battery (traction batt ery) and allows the air conditioning
to be operated by remote control.
If the Remote Air Conditioning System is used while the charging
cable is connected to the vehicle, the reduction of charge in the
hybrid battery (traction battery) will be suppressed to allow you to
use electricity from an external power source.
Charging will be conducted automatically after the Remote Air Condi-
tioning System is stopped.
■ Before leaving the vehicle
Check the temperature setting of the air conditioning system.
The Remote Air Conditioning System will operate in accordance with
the temperature settings of the air conditioning system.
■Activating the Remote Air Conditioning System
Press and hold the to
operate the Remote Air Condi-
tioning System.
The system will shut off if a
door is opened.
The system can be stopped by
pressing the twice.

CAUTION
■Precautions for the Remote Air Conditioning System
● Do 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 level due to features such as the automatic shut-off. Chil-
dren and pets left inside the vehicle may suffer heatstroke or dehydra-
tion, or could result in death or serious injury.
• The wipers can be operated during system operation. Children or pets left inside the vehicle may mistakenly operate these and cause an acci-
dent.
● Depending on the surrounding environment , signals from the wireless
switch may transmit further than expected. Pay appropriate attention to
the vehicle’s surroundings and use the switch only when necessary.
● Turn the wipers off. If the Remote Air Conditioning System operates while
the wiper switch is in the on position, the wipers may operate and objects
may get caught in the wiper blades.
● Do not operate the if the hood is open. The air conditioning may
operate unintentionally and objects may be drawn into the electrical cool-
ing fan.
