Remote Air Conditioning System
If the Remote Air Conditioning System is used while the chargin g
cable is connected to the vehicl e, the reduction of charge in the hybrid
battery (traction battery) will be suppressed to allow you to u se elec-
tricity from an exte rnal power source.
Charging will be conducted automatically after the Remote Air C ondition-
ing System is stopped.
Check the temperature setting o f the air conditioning system.
(  P. 496, 508)
The Remote Air Conditioning System will operate in accordance w ith the

■ Windshield 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.
■ Using the heater via the Remote Air Conditioning System
When the outside heat exchanger becomes frosted over, heating p erfor-
mance may decline due to automatically switching to the frost r emoval opera-
tion.

NOTICE
■When using a high pressure car wash
● When washing the vehicle, do not let water of the high pressure washer hit
directly or the vicinity of the camera. Due to the shock from t he high pres-
sure water, it is possible the device may not operate as normal .
● Do not bring the nozzle tip close to boots (rubber or resin man ufactured
cover), connectors or the following parts. The parts may be dam aged if
they come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
● Keep the cleaning nozzle at least 11.8 in. (30 cm) away from th e vehicle
body. Otherwise resin section, such as moldings and bumpers, ma y be
deformed and damaged. Also, do not continuously hold the nozzle in the
same place.
● Do not spray the lower part of the windshield continuously. If water enters
the air conditioning system intake located near the lower part of the wind-
shield, the air conditioning system may not operate correctly.
● Do not wash the underside of the vehicle using a high pressure car
washer.
● Do not use the washer on the area around the charging port lid. Water
could get into the charging inlet and could damage the vehicle.
■ When raising the windshield wiper arms
Make sure to hold the hook parts of the
wiper arms to raise them.
Do not hold only the wiper blades when
raising them, or it may cause deformation
of the wiper blades.
