WARNING
●Do not use the system in the following situations, as the syste m may be
unable to correctly assist you in reaching the target parking s pot and may
lead to an unexpected accident.
• In an area that is not a parking lot
• A parking lot that is not paved and has no parking space lines, such as a sand or gravel parking lot
• A parking lot that has a slope or undulations in the road
• A frozen, snow-covered or slippery road
• The asphalt is melting due to hot weather
• There is an obstacle between the vehicle and the target parking spot
• Using tire chains
● Do not use tire other than that provided by the manufacturer. The system
may not operate properly. When replacing tires, contact your Toyota
dealer.
● The system may not be able position the vehicle in the set location in the
following situations.
• The tires are extremely worn or the tire pressure is low
• The vehicle is carrying very heavy load
• The vehicle is tilted due to having luggage, etc. located on one side of
the vehicle
• There are road heaters installed in the parking lot to prevent the road
surface from freezing.
In any other situations when the set position and vehicle posit ion greatly
differ, have the vehicle inspected by your Toyota dealer.
● Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when depar ting from a
parallel parking spot. However, this function may not be usable if obsta-
cles or people are detected in front of the vehicle. Only use t his function
when departing from a parallel parking spot. In the event that the steering
control operates, either turn the system off using the S-APGS s witch or
operate the steering wheel to stop the control.
● If exit parallel parking assist mode is mistakenly used in the following situ-
ations, the vehicle may make contact with an obstacle.
The departure function is operated in a direction where an obst acle is
present, but the obstacle is not detected by the side sensors ( situations
such as when the vehicle is directly beside a pole).

■Heating
●In HV mode, the gasoline engine may operate in order to extract heat from
the engine coolant via the heater.
● In EV mode, heating is done by a heat pump system.
• When the outside temperature is low or it is snowing, compared to con-
ventional vehicles, heating may be less effective and warm air may not
come out.
• If frost has formed on the outside heat exchanger, the heating perfor-
mance will decline. The frost can be removed from the outside heat
exchanger by operating the Remote Air Conditioning System befor e driv-
ing ( P. 518). When frosted over, the heating operation of the Remote
Air Conditioning System starts after defrosting.
• When is turned on, the heating is controlled optimally. Therefore, the set heating performance may not be achieved even if the fan speed
setting is increased.
● In the following situations the gasoline engine may operate in order to
extract heat from the engine coolant via the heater even in EV mode.
• The outside temperature is approximately 14°F (-10°C) or low
• is operating
■ Using automatic mode
Fan speed is adjusted automatically according to the temperatur e setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ Water droplets during air conditioning operation• When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte-
rior. However, it is not a malfunction.
In this situation, the air temperature
from the outlets may not change even
though the set temperature is raised.
The outside heat exchanger, accumulator
and air conditioning piping may incur con-
densation or frost may form. During or
after the air conditioning operation, water
droplets may fall from the vehicle. How-
ever, it is not a malfunction.

■Operating conditions
The system will only operate if all of the following conditions are met:
●The shift position is in P.
● The power switch is off.
*
●All doors are closed.
● The hood is closed.
*: The Remote Air Conditioning System cannot be used for approxim ately 3
minutes and a half after the power switch is turned off.
■ Remote Air Conditioning S ystem automatic shut-off
The system will automatically shut off under the following cond itions:
● About 10 minutes have passed since operation began
● Any one of the operating conditions is not met
The system may also shut off if the charge level of the hybrid battery (traction
battery) drops to low.
■ Conditions affecting operation
The system may not start in the following situations:
●The charge level of the hybrid battery (traction battery) is lo w
● The outside temperature is extremely low
● When the hybrid system is cool (for example, after being left f or a long time
in low temperatures)
■ 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.
