PRIUS +_OM_OM47821E_(EE)As shown below, the driving conditions of the vehicle can be con-
firmed by checking the status of the indicator.
*1: The images are examples only, and may vary slightly from actual condi-
tions.
*2: The displayed status is intended as a guide, and may differ from the
actual status.
*3: The gasoline engine will automatically stop and restart under various
conditions.

PRIUS +_OM_OM47821E_(EE)Press and hold the “DISP” button for 1 second or more to
complete the setup.
If setup is not completed by pressing and holding the “DISP” button
for 1 second or more, or if nothing is operated within approximately
10 seconds, the screen will return and the settings will be lost.
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 or EV drive mode. (P. 221, 226)
The vehicle speed is approximately 130 km/h (80 mph) or higher.
Eco Driving Indicator Light can be set to activated or deactivated.
(P. 245)
Remaining hybrid battery (traction battery) charge display
The charge amount of the hybrid battery (traction battery) is automatically
controlled by the hybrid system. For this reason, even if electricity is recov-
ered via the regenerative braking, or electricity is generated via the gasoline
engine, the displayed hybrid battery (traction battery) charge amount may
not reach the highest level (level 8). However, this does not indicate a mal-
function.

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 operation and driving conditions are the same.
Brightness of the instrument cluster light
If the headlight switch is turned to ON while the surrounding area is dark, the
instrument cluster lights will dim.
When disconnecting and reconnecting 12-volt battery terminals
The average fuel consumption and cruising range will be reset.
NOTICE
To prevent damage to the engine and its components
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. (P. 528)
The trip information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.

PRIUS +_OM_OM47821E_(EE)
When the TRC/VSC/ABS systems are operating
The slip indicator light will flash
while the TRC/VSC/ABS sys-
tems are operating.
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
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.

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 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.

Interior features
PRIUS +_OM_OM47821E_(EE)
Pollen removal mode
In order to prevent the windshield from fogging up when the outside air is
cold, the following may occur:
• Outside air mode does not switch to recirculated air mode.
• The air conditioning system operates automatically.
• The operation cancels after 1 minute.
In rainy weather, the windows may fog up. Press .
Outside temperature display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
When stopped, or driving at low speeds (less than 25 km/h [16 mph])
When the outside temperature has changed suddenly (at the entrance/
exit of a garage, tunnel, etc.)
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 improve air conditioning performance, perform the following operations:
Adjust the fan speed and temperature
Turn off Eco drive mode (P. 226)
Customize the air conditioning control of Eco drive mode. (P. 554)
When outside air temperature is below 0 C (32 F)
The cooling and dehumidification function may not operate even when
is pressed.

CAUTION
When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.
When cleaning the windshield
When the upper part of the windshield where the raindrop sensor is
located is touched by hand
When a wet rag or similar is held close to the raindrop sensor
If something bumps against the windshield
If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in hands
being caught or other serious injuries and
cause damage to the wiper blades.
