When driving
PRIUS +_OM_OM47821E_(EE)
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.

2-5. Driving information
Cargo and luggage
Take notice of the following information about storage precautions,
cargo capacity and load:
Stow cargo and luggage in the luggage compartment whenever
possible.
Be sure all items are secured in place.
To maintain vehicle balance while driving, position luggage
evenly within the luggage compartment.
For better fuel economy, do not carry unnecessary weight.

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.

4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
Automatic car washes
Fold the mirrors and remove the antenna before washing the vehicle.
Start washing from the front of the vehicle. Make sure to re-install the
antenna and extend the mirrors before driving.
Brushes used in automatic car washes may scratch the vehicle surface
and harm your vehicle’s paint.
Roof antenna, rear spoiler may not be washable in some automatic car
washes. There may also be an increased risk of damage to vehicle.
High pressure car washes
Do not allow the nozzles of the car wash to come within close proximity
of the windows.
Before using the car wash, check that the fuel filler door on your vehicle
is closed properly.
Perform the following to protect the vehicle and maintain it in prime
condition:
Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any
dirt and dust.
Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
Wipe away any water.
Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.

Maintenance and care
PRIUS +_OM_OM47821E_(EE)
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 cooling 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. 410)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.

PRIUS +_OM_OM47821E_(EE)
Tire inflation pressure
Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
Reduced fuel efficiency
Reduced driving comfort and tire life
Reduced safety
Damage to the drive train
If a tire needs frequent inflating, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Make sure to maintain the proper tire inflation pressure. Tire inflation
pressure should be checked at least once per month. However,
Toyota recommends that tire inflation pressure be checked once
every two weeks. (P. 550)

Warning lightWarning light/DetailsCorrection procedure

(Only outer
frame flashes)Low hybrid battery (traction
battery) warning light (warning
buzzer)
Hybrid battery (traction battery)
level becomes low because the
shift position is in N for long
timeBecause recharging
is not possible when
the shift position is in
N, shift the shift posi-
tion to P when park-
ing the vehicle for a
long time.

(Turns on)
(If equipped)Pre-crash safety system warn-
ing light
Indicates that the PCS is not
currently functional because
the grille or the radar sensor is
dirty, or the system has over-
heated.• Check the grille and
the sensor and clean
them if they are dirty.
• In case of overheat-
ing, the system will
become functional
once the system
cools down.
