When driving
■
Driving in Eco drive mode
The multi-information display will automatically switch the display to Hybrid
System Indicator, regardless of which display is currently being shown.
(P. 268)
■ Touch tracer display (if equipped)
● The touch tracer display can be set to not display even if the steering
switches are touched.
● Only the circular, rubber-covered switches have a built-in touch sensor.
Touching any of the other switches will not display the touch tracer dis-
play.
■ Display settings can be changed when
The vehicle speed is less than approximately 5 mph (8 km/h).
■ Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help
improve fuel efficiency and reduce exhaust emissions etc. There are times
when the engine speed that is displayed may differ even when vehicle oper-
ation and driving conditions are the same.
■ When the 12-volt battery is disconnected
The following data will be reset.
● Average fuel consumption
● Distance to empty
● Average vehicle speed
● EV driving ratio
● Clock
● Display settings
● Trip meter

When driving
Turning on the high beam headlights
With the headlights on, push
the lever away from you to
turn on the high beams.
Pull the lever toward you to the
center position to turn the high
beams off.
Pull the lever toward you and
release it to flash the high
beams once.
You can flash the high beams
with the headlights on or off.
■Daytime running light system
● For the U.S.A.: To make your vehicle more visible to other drivers, the
daytime running lights turn on automatically whenever the hybrid system
is started and the parking brake is released.
Daytime running lights can be turned off by operating the switch. (if
equipped)
For Canada: To make your vehicle more visible to other drivers, the day-
time running lights turn on automatically (at a reduced intensity) whenever
the hybrid system is started and the parking brake is released. Daytime
running lights are not designed for use at night.
● For Canada: Compared to turning on the headlights, the daytime running
light system offers greater durability and consumes less electricity, so it
can help improve fuel economy.

Interior features
■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature set-
ting and ambient conditions, etc. As a result, the following may occur.
● Immediately after
is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
● Cool air may flow to the area around the upper body when the heater is
on.
■ Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched to
in accordance with under these condition, such as temperature setting and
inside temperature.
Also, outside air mode may be automatically switched to when the outside
temperature is low.
■ When the outside temperature exceeds 75 °F (24 °C) and the air condi-
tioning system is on
● In order to reduce the air conditioning power consumption, the air condi-
tioning system may switch to recirculated air mode automatically. This
may also reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the “POWER”
switch is turned to ON mode.
● It is possible to switch to outside air mode at any time by pressing
.
■ Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used.

Interior features
■If air flow from the vents decreases dramatically
The filter may be clogged. Contact your Toyota dealer.
■ 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. 247)
● Customize the air conditioning control of Eco drive mode. ( P. 639)
■ When outside air temperature is below 32 °F (0 °C)
The cooling and dehumidification function may not operate even when
is pressed.
■ Air conditioning odors
● 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.

Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system moni-
tors the operation of th e emission control system.
■If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere
in the emission control system. Your vehicle may not pass the I/
M test and may need to be repaired. Contact your Toyota dealer
to service the vehicle.
■ Your vehicle may not pass the I/M test in the following situa-
tions:
●When the 12-volt battery is disconnected or discharged
Readiness codes that are se t during ordinary driving are
erased.
Also, depending on your driving habits, the readiness codes
may not be completely set.
● When the fuel tank cap is loose
The malfunction indicator lamp comes on indicating a tempo-
rary malfunction and your vehi cle may not pass the I/M test.
■ When the malfunction indicator lamp still remains on after
several driving trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
