the air conditioning system.
( P.421)
The Remote Air Conditioning System
will operate in accordance with the tem-
perature settings of the air conditioning
system.
Press and hold “A/C” on the wire-
less remote control to operate the
Remote Air Conditioning System.
The system will shut off if a door is
opened.
The system can be stopped by press-
ing “A/C” twice.
■Operating conditions
The system will only operate if all of the following conditions are met:
●The power switch is OFF.
●All doors are closed.
●The hood is closed.
■Remote Air Conditioning System
automatic shut-off
The system will automatically shut off under the following conditions:
●About 20 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 traction battery drops to low.
■Conditions affecting operation
The system may not start in the follow- ing situations:
●The charge level of the traction bat-tery is low
●When the EV system is cool (for example, after being left for 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
Remote Air Conditioning
System
The Remote Air Conditioning
System uses electrical energy
stored in the traction battery
and allows the air conditioning
to be operated by remote con-
trol.
If the Remote Air Conditioning
System is used while the
charging cable is connected to
the vehicle, the reduction of
charge in the traction battery
will be suppressed to allow
you to use electricity from an
external power source.
Charging will be conducted auto-
matically after the Remote Air
Conditioning System is stopped.

that the doors have been locked.
■Conditions affecting operation
 P. 2 0 4
■While the Remote Air Conditioning System is operating
●Depending on the operating condition of the Remote Air Conditioning Sys-
tem, the electric fan may spin and an operating noise may be heard.However, this does not indicate a mal-
function.
●The Remote Air Conditioning System
may stop operating temporarily if other features that use electricity (for example, the seat heater, lights, wind-
shield wipers) are in operation or if the charge level of the 12-volt battery becomes low.
●The headlights, windshield wiper, meter, etc. will not operate.
●The intrusion sensor will automatically be canceled.
■Electronic key battery depletion

■Customization
Setting (e.g. Operation using “A/C” on the wireless remote control) can be changed. (Customizable features:
 P.572)
WARNING
■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 or low level due to features such as the automatic shut-off. Chil-
dren and pets left inside the vehicle may suffer heatstroke dehydration or hypothermia, or could result in
death or serious injury.
●Depending on the surrounding envi-
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.
●Do not operate “A/C” if the hood is open. The air conditioning may
operate unintentionally and objects may be drawn into the electrical cooling fan.
NOTICE
■To prevent the traction battery
from being discharged through incorrect operation
Use “A/C” only when necessary.

The coolant level is satisfactory if it
is between the “MAX” and “MIN”
lines on the reservoir when the EV
system is cold.
Reservoir cap
“MAX” line
“MIN” line
If the level is on or below the “MIN” line,
add coolant up to the “MAX” line.
■Coolant selection
In order to ensure maximum perfor-
mance of the traction battery cooling system and limit risks of battery short-circuit and other damage to your vehi-
cle, Toyota recommends using “Toyota Genuine Traction Battery Coolant” or
similar high-quality ethylene glycol-
based, low electric conductivity coolant, non-amine and non-borate coolant with azole additives.
Toyota cannot guarantee that the use of a product other than “Toyota Genuine Traction Battery Coolant” will prevent
risks of battery short-circuit or other damage.
Never use water as it will cause dam-
age.
Do not reuse coolant that has been removed from the radiator.
For more details about coolant, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■If the coolant level drops within a short time of replenishing
Visually check the hoses, heater coolant
reservoir caps, drain cock and water pump.
If you cannot find a leak, have any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer, test the cap and check for leaks
in the cooling system.
WARNING
■When the electric cooling fan is operating
Do not touch the motor compartment.
With the power switch in ON, the electric cooling fan may automatically
start to run if the air conditioning is on and/or the coolant temperature is high. Be sure the power switch is OFF
when working near the electric cool- ing fan or radiator grille.

WARNING
■When the heater system is hot
Do not remove the heater coolant res-
ervoir caps.
The heater system may be under pressure and may spray hot coolant if
the cap is removed, causing serious injuries, such as burns.

NOTICE
■Precautions for the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehicle use. Do not connect the repair kit to any
other source.
●Place the repair kit in a storage to
prevent it from being exposed to dirt or water.
●Store the repair kit in the luggage compartment out of reach of chil-dren.
●Do not disassemble or modify the repair kit. Do not subject parts such
as the air pressure indicator to impacts. This may cause a malfunc-tion.
■To avoid damage to the tire pres-sure warning valves and trans-
mitters
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is used, contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer or other qualified ser-vice shop as soon as possible. After
use of liquid sealant, make sure to replace the tire pressure warning valve and transmitter when repairing
or replacing the tire. ( P.479)
