■ Linked to air conditioning operations
When the air conditioning is
set to ECO LO or ECO HI
mode, the seat heater is auto-
matically operated and its tem-
perature automatically
adjusted according to the out-
side temperature and air con-
ditioning settings.
“ECO” is shown on the display.

■
The seat heaters can be used when
The “POWER” switch is in ON mode.
■ When not in use
Turn the seat heater off.
■ Front passenger seat heater
●When the air-conditioning is in ECO LO or ECO HI mode, the seat heater
automatically turns on/off depending on whether the front passenger seat
is occupied or not.
● When the seat heater is operating in manual mode, it does not automati-
cally turn on/off depending on whether the front passenger seat is occu-
pied or not.
● In order to prevent unintended seat heater operation, do not place lug-
gage on the passenger seat.
The sensor may mistakenly judge the seat to be occupied and turn the
seat heater on.
■ Manual Mode
Each time the seat heater cont rol is touched, the seat heater's
operation or temperature setting changes.

CAUTION
■Burns
●Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping drugs, cold remedies, etc.)
● Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
● Do not use the seat heater more than necessary. Doing so may cause
minor burns or overheating.
NOTICE
■To prevent seat heater damage
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
■ To prevent 12-volt battery discharge
Turn the seat heaters off when the EV system is off.

Maintenance and care
NOTICE
■
Cleaning detergents
●Do not use organic substances such as benzene or gasoline, acidic or
alkaline solutions, dye, bleach or other detergent. Doing so may discolor
the vehicle interior or cause streaks or damage to painted surfaces.
● Do not use polish wax or polish cleaner. The instrument panel's or other
interior part’s painted surface may be damaged.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration o\
f
leather surfaces:
●Remove any dust or dirt from leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components such as the audio system above or
under the floor of the vehicle. Water may also cause the body to rust.
■ Cleaning the inside of the rear window
●Do not use glass cleaner to clean the rear window, as this may cause
damage to the rear window defogger heater wires or antenna. Use a cloth
dampened with lukewarm water to gently wipe the window clean. Wipe the
window in strokes running parallel to the heater wires or antenna.
● Be careful not to scratch or damage the heater wires or antenna.

Do-it-yourself ser vice precautions
If you perform maintenance yourself, be sure to follow the correct
procedures as given in these sections.
ItemsParts and tools

CAUTION
The motor compartment contains many mechanisms and fluids that may move
suddenly, become hot, or become electrically energized. To avoid death or
serious injury, observe the following precautions:
■When working on the motor compartment
●Make sure that the indicator on the “POWER” switch and the “READY”
indicator are both off.
● Keep hands, clothing and tools away from the moving fans.
● Be careful not to touch the motor, power control unit, radiator, heater, etc.
right after driving as they may be hot. Coolant and other fluids may also be
hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
motor compartment.
● Do not smoke, cause sparks or expose an open flame to the 12-volt bat-
tery. 12-volt battery fumes are flammable.
● Be extremely cautious when working on the 12-volt battery. It contains poi-
sonous and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
● Never touch, disassemble, remove or replace the high voltage parts,
cables and their connectors. It can cause severe burns or electric shock
that may result in death or serious injury.
■ When working near the electric c ooling fans or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 360)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

■Coolant selection
Only use “Zerex G 48” or “Glysantin G 48”.
“Zerex G 48” and “Glysantin G 48” are blue in color.
Reference:
The dilution ratio for both “Zerex G 48” and “Glysantin G 48” is 50% cool-
ant and 50% deionized water. (Minimum temperature: approximately -32 F
[-36 C])
For more details about motor/traction battery coolant, contact your Toyota
dealer.
■ If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, motor/traction battery coolant reservoir
cap, drain cock and water pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the cooling system.
CAUTION
■When the EV system is hot
Do not remove the coolant reservoir cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
■When adding coolant
●Coolant is neither plain water nor straight antifreeze. The correct mixture
of water and antifreeze must be used to provide proper lubrication, corro-
sion protection and cooling. Be sure to read the antifreeze or coolant label.
● Do not add heater coolant to the motor or traction battery coolant reser-
voirs. Doing so will negatively affect the coolant’s performance and cause
the cooling system to malfunction.
■ If you spill coolant
Be sure to wash it off with water to prevent damage to parts or paint.

Maintenance and care
Heater coolant
The coolant level is sati sfactory if it is between the “F” and “L” lines on
the reservoir when the heater system is cold.
Reservoir cap
“F”
“L”
If the level is on or below the “L”
line, add coolant up to the “F” line.
(P. 485)
■ Coolant selection
Only use “Toyota Super Long Life Coolant” or 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 pink in color.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50%
deionized water. (Minimum temperature: -31 F [-35 C])
For more details about heater coolant, contact your Toyota dealer.
■ If the coolant level drops within a short time after replenishing
Visually check the hoses, heater coolant reservoir cap, drain cock and water
pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the heater system.
CAUTION
■When the heater is in use or just after use
Do not remove the coolant reservoir cap.
The heater system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
