■ Eco Driving Indicator Light
Eco Driving Indicator Light will turn on when driving power is lower than the
upper limit of Eco driving. It will turn off when the acceleration exceeds the
Eco driving accelerator upper limit or when the vehicle is stopped.
Eco Driving Indicator Light will not operate in the following conditions:
● The shift position is anything other than D.
● The driving mode is set to power mode. ( P. 247)
● The vehicle speed is approximately 80 mph (130 km/h) or higher.
Eco Driving Indicator Light is also displayed when 5-minute consumption, 1-
minute consumption or monthly fuel consumption record is displayed.
Eco Driving Indicator Light can be set to activated or deactivated. ( P. 277)
■ Hybrid System Indicator display when in EV mode
The movement of the bar in response to the operation of the accelerator
pedal may differ in accordance with the status of the hybrid battery (traction
battery). However, this does not indicate a malfunction.
After switching the “POWER” switch to
ON mode, “welcome to PRIUS” is dis-
played while system operation is
checked. When the system check is com-
plete, the normal screen will return.

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 on snowy roads or in other bright environments
When the highest level of brightness has been reached, the display can b\
e
made even brighter by pressing and holding “ ” on the brightness control
button.
Pressing “ ” on the brightness control button or turning the “POWER” switch
off will cause the brightness level to revert to the original level.
■ Display speed setting function
The speedometer can be set to display only when a desired vehicle speed is
reached.
Press and hold the “HUD” main switch while the vehicle is stopped
and while the head-up display is showing only the speedometer.
The speedometer will begin to flash.
Set the desired display speed on the speedometer by pressing “ ”
and “ ” on the display position adjustment button.
Press “ ” to raise the speed and “ ” to lower. The speed will change
by 1 mph (1.6 km/h) each time the button is pressed, and continu-
ously by 10 mph (16 km/h) when the button is pressed and held.
Press and hold the “HUD” main switch to finish setting.
■ Head-up display
The head-up display may seem dark and hard to see when viewed through

Automatic headlight leveling system (if equipped)
The level of the headlights is automatically adjusted according to the number
of passengers and the loading condition of the vehicle to ensure that the
headlights do not interfere with other road users.
■ Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features P. 639)

CAUTION
■
Caution regarding the use of washer fluid
When it is cold, do no use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
■ To prevent 12-volt battery discharge
Do not leave the wipers on longer than necessary when the hybrid system is
off.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have a service technician inspec t the condition of the 12-volt
battery.
● Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.

CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, blocking
your vision.
NOTICE
■To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the
hybrid system is not operating.

Interior features
Remote Air Conditioning System
The Remote Air Conditioning System uses electrical energy stored
in the hybrid battery (traction batt ery) and allows the air conditioning
to be operated by remote control.
If the Remote Air Conditioning System is used while the charging
cable is connected to the vehicle, the reduction of charge in the
hybrid battery (traction battery) will be suppressed to allow you to
use electricity from an external power source.
Charging will be conducted automatically after the Remote Air Condi-
tioning System is stopped.
■ Before leaving the vehicle
Check the temperature setting of the air conditioning system.
The Remote Air Conditioning System will operate in accordance with
the temperature settings of the air conditioning system.
■Activating the Remote Air Conditioning System
Press and hold the to
operate the Remote Air Condi-
tioning System.
The system will shut off if a
door is opened.
The system can be stopped by
pressing the twice.
