The engine may be overheating if the high coolant temperature warning light
comes on or flashes. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (oP. 6 0 7 )

When driving
■Sounds and vibrations caused by the ABS, brake assist, VSC and
TRAC
●A sound may be heard from the engine compartment when the hybrid
system is started, just after the vehicle begins to move, if the brake pedal
is depressed forcefully or repeatedly, or 1-2 minutes after the hybrid sys-
tem is stopped. This sound does not indicate that a malfunction has
occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
•Vibrations may be felt through the vehicle body and steering.
•A motor sound may be heard after the vehicle comes to a stop.
•The brake pedal may pulsate slightly after the ABS is activated.
•The brake pedal may move down slightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the hybrid
system off. The EPS system should return to normal within 10 minutes.
■Electric power steering system warning light (warning buzzer)

Interior features
■If air flow from the vents decreases dramatically
The filter may be clogged. Contact your Toyota dealer.
■Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency:
●Engine speed and compressor operation controlled to restrict heating/
cooling capacity
●Fan speed restricted when automatic mode is selected
To i m p r o v e a i r c o n d i t i o n i n g p e r f o r m a n c e , p e r f o r m t h e f o l l o w i n g o p e r a t i o n s :
●Adjust the fan speed
●Turn off Eco drive mode (oP. 2 5 1 )
●Customize the air conditioning control of Eco drive mode. (oP. 6 4 7 )
■When outside air temperature is below 32°F (0°C)
The cooling and dehumidification function may not operate even when
is pressed.

●To l e t f r e s h a i r i n , s e t t h e a i r c o n d i t i o n i n g s y s t e m t o t h e o u t s i d e a i r m o d e .
●During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
●To r e d u c e p o t e n t i a l o d o r s f r o m o c c u r r i n g :
•It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
•The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
■Customization
Settings (e.g. enable/disable automatic operation of the air conditioning
compressor when the “AUTO” switch ON) can be changed.

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 p r e v e n t s e a t h e a t e r d a m a g e
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 p r e v e n t 1 2 - v o l t b a t t e r y d i s c h a r g e
Turn the seat heaters off when the hybrid system is off.

After the hybrid system has
cooled down sufficiently, inspect
the hoses and radiator core
(radiator) for any leaks.

If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
The following may indicate that your vehicle is overheating.
●The high coolant temperature warning light (oP. 5 3 8 ) c o m e s o n
