■Operation of the air conditio ning 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 improve air conditioning performance, perform the following operations:
● Adjust the fan speed
● Turn off Eco drive mode ( P. 207)
● Customize the air conditioning control of Eco drive mode. ( P. 602)
■ When outside air temperature is below 32°F (0°C)
The cooling and dehumidification function may not operate even when
is pressed.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
● 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 reduce potential odors from occurring:
• 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
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle, leading to a serious accident.
■When installing the driver’s floor mat
●Do not use floor mats designed for other models or different model year
vehicles, even if they are Toyota Genuine floor mats.
● Only use floor mats designed for the driver’s seat.
● Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
● Do not use two or more floor mats on top of each other.
● Do not place the floor mat bottom-side up or upside-down.
■ Before driving
●Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.

telematics device being in operative condition, cellular connection avail-
ability, and GPS satellite signal reception, which can limit the ability to
reach the response center or receive emergency service support. Enroll-
ment and Telematics Subscription Service Agreement required. A variety
of subscription terms is available; charges vary by subscription term
selected.
● Automatic Collision Notification, Emergency Assistance, Stolen Vehicle
Location, and Enhanced Roadside Assistance will function in the United
States, including Hawaii and Alaska, and in Canada. No Safety Connect
services will function outside of the United States in countries other than
Canada.

■ When contacting the response center
You may be unable to contact the response center if the network is busy.
■ Safety Connect backup battery depletion
An exclusive backup battery is built in to assist the Automatic Collision Noti-
fication, which is activated when impact above a certain level is applied to
the vehicle, or when the airbags operate. This battery is a primary battery,
and cannot be recharged. The red LED indicator will flash to indicate that the
battery should be replaced.
The backup battery will need to be replaced if the Automatic Collision

■ Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision,
the system is design ed to automatically call the response center.
The responding agent receives th e vehicle’s location and attempts
to speak with the vehicle occup ants to assess the level of emer-
gency. If the occupants are unable to communicate, the agent
automatically treats the call as an emergency, contacts the nearest
emergency services provider to describe the situation, and
requests that assistance be sent to the location.

Maintenance and care
CAUTION
The engine 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 engine 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 fan.
● Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■ 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. 435)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

■After recharging/reconnecting the 12-volt battery
●Unlocking the doors using the smart key system may not be possible
immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the
doors.
● Start the hybrid system with the “POWER” switch in ACCESSORY mode.
The hybrid system may not start with the “POWER” switch turned off.
However, the hybrid system will operate normally from the second
attempt.
● The “POWER” switch mode is recorded by the vehicle. If the 12-volt bat-
tery is reconnected, the vehicle will return the “POWER” switch mode to
the status it was in before the 12-volt battery was disconnected. Make
sure to turn off the power before disconnect the 12-volt battery. Take
extra care when connecting the 12-volt battery if the “POWER” switch
mode prior to discharge is unknown.
● Restart the hybrid system, depress the brake pedal, and confirm that it is
possible to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact your Toyota dealer.
