Interior features
■Heating
●Heating is done by an electric heat pump system.
● When the outside temperature is low or it is snowing, compared to conven-
tional vehicles, heating may be less effective and warm air may not come
out.
● When outside condenser is cold, condensed water from the condenser’s
surface may fall under the vehicle. However, it is not a malfunction.
● When the outside condenser is frosted over, the temperature display blinks,
fan speed declines and it may become harder to heat the interior. However,
it is not a malfunction.
■ How to defrost the outside condenser
If frost has formed of the outside condenser ( P. 277), the heating perfor-
mance will decline. The frost can be removed from the outside condenser by
either one of the following procedures.
● Operate the Remote Climate Control before driving. ( P. 228)
When frosted over, the heating operation starts after defrosting.
● Press and hold for approximately 2 seconds or more while the vehicle
is stopped to defrost. It will be canceled when the vehicle begins to mo\
ve.
■ Using automatic mode
Fan speed is adjusted automatically according to the temperature 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.
■ “MAX” mode
●For quick warming or cooling, press .
Simultaneous use together with automatic mode will be more effective.
● When “MAX” mode is used, traction bat tery consumption is greater than
usual and the driving range decreases.
● If the amount of the remaining traction battery power is low, the “MAX” mode
operation may be limited.
● If the power switch is turned off while “MAX” mode is active, even if the
power switch is turned to ON mode again, “MAX” mode will remain off.

2787-3. Do-it-yourself maintenance
The coolant level is satisfactory if it is between the “F” (Full) and “L”
(Low) lines on the reservoir when the EV system is cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L”
line, add coolant up to the “F”
line. ( P. 390)
■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -31 F [-35 C])
For more details about inverter coolant, contact your Scion dealer.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, inverter coolant reservoir cap, drain cock
and water pump.
If you cannot find a leak, have your Scion dealer test the cap and check for
leaks in the cooling system.

CAUTION
■When the EV system is hot
Do not remove the inverter coolant reservoir cap. ( P. 391)
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
