2023 TOYOTA PRIUS PRIME Face ID

2565-2. Driving procedures
*: To improve fuel efficiency and reduce noise, set the shift posi-
tion in D for normal driving.
■When driving with dynamic
radar cruise control activated
Even when switching the driving
mode to sport mode with the intent
of enabling engine braking, engine
braking will not activate because
dynamic radar cruise control will not
be canceled.
■If a message about a shift oper-
ation is shown
To prevent the shift position from
being selected incorrectly or the
vehicle from moving unexpectedly,
the shift position may be changed
automatically or operating the shift
lever may be required . In this case,
change the shift position following
the messages on the multi-informa-
tion display.

WARNING
■When driving on slippery
road surfaces
Do not accelerate or shift the shift
position suddenly.
Sudden changes in engine brak-
ing may cause the vehicle to spin
or skid, resulting in an accident.
NOTICE
■Hybrid battery (traction bat-
tery) charge
If the shift position is in N, the
hybrid battery (traction battery)
will not be charged. To help pre-
vent the battery from discharging,
avoid leaving the N position
selected for an extended period of
time.
■Situations where shift con-
trol system malfunctions are
possible
If any of the following situations
occurs, shift control system mal-
functions are possible.
Immediately stop the vehicle in a
safe place on level ground, apply
the parking brake, and then con-
tact your Toyota dealer.

2Turn the headlight switch to
the or position.
When the headlight switch lever is
in the low beam position, the AHB
system will be enabled and the
AHB indicator will illuminate.
■Automatic operating condi-
tions of the high beams
●When all of the following condi-
tions are met, the high beams will
illuminate automatically:
• The vehicle speed is approxi-
mately 21 mph (34 km/h) or more.
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with lights on.
• There are few streetlights or other
lights on the road ahead.
●If any of the following conditions
are met, the headlights will
change to the low beams:
• Vehicle speed drops below
approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• There is a vehicle ahead with lights on.
• There are many streetlights or
other lights on the road ahead.
■Front camera detection
●In the following situations, the high
beams may not be automatically
changed to the low beams:
• When a vehicle cuts in front of your vehicle
• When another vehicle crosses in front of the vehicle • When vehicles ahead are repeat-
edly detected and then hidden
due to repeated curves, road
dividers or roadside trees
• When a vehicle ahead approaches from a far lane
• When a vehicle ahead is far away
• When a vehicle ahead has no lights
• When the lights of a vehicle ahead are dim
• When a vehicle ahead is reflecting
strong light, such as own head-
lights
• Situations in which the sensors
may not operate properly: P.289
●The headlights may change to the
low beams if a vehicle ahead that
is using fog lights without its head-
lights turned on is detected.
●House lights, street lights, traffic
signals, and illuminated billboards
or signs may cause the high
beams to change to the low
beams, or the low beams to
remain on.
●The following may change the tim-
ing at which the headlights
change to the low beams:
• The brightness of lights of vehi-
cles ahead
• The movement and direction of vehicles ahead
• The distance between the vehicle and a vehicle ahead
• When a vehicle ahead only has
lights illuminate d on one side
• When a vehicle ahead is a two- wheeled vehicle
• The condition of the road (gradi- ent, curve, condition of the road
surface, etc.)
• The number of passengers and amount of luggage
●The headlights may change
between the high beams and low
beams unexpectedly.
●Bicycles and other small vehicles
may not be detected.

Driving
5-4.Refueling
Close all the doors and win-
dows, and turn the power
switch to OFF.
 Confirm the type of fuel.
■Fuel types
 P.607
■Fuel tank opening for unleaded
gasoline
To help prevent incorrect fueling,
your vehicle has a fuel tank opening
that only accommodates the spe-
cial nozzle on unleaded fuel pumps.
Opening the fuel tank
cap
The fuel tank of your vehicle
has a special structure,
which requires a reduction
in fuel tank pressure before
refueling. After the opener
switch has been pressed, it
will take several seconds
until the vehicle is ready for
refueling.
Before refueling the vehi-
cle
WARNING
■When refueling the vehicle
Observe the following precautions
while refueling the vehicle. Failure
to do so may result in death or
serious injury.
●After exiting the vehicle and
before opening the fuel door,
touch an unpainted metal sur-
face to discharge any static
electricity. It is important to dis-
charge static electricity before
refueling because sparks result-
ing from static electricity can
cause fuel vapors to ignite while
refueling.
●Always hold the grips on the
fuel tank cap and turn it slowly
to remove it.
A whooshing sound may be
heard when the fuel tank cap is
loosened. Wait until the sound
cannot be heard before fully
removing the cap. In hot
weather, pressurized fuel may
spray out of the filler neck and
cause injury.
●Do not allow anyone that has
not discharged static electricity
from their body to come close to
an open fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances that
are harmful if inhaled.
●Do not smoke while refueling
the vehicle.
Doing so may cause the fuel to
ignite and cause a fire.
●Do not return to the vehicle or
touch any person or object that
is statically charged. This may
cause static electricity to build
up, resulting in a possible igni-
tion hazard.
■When refueling
Observe the following precautions
to prevent fuel overflowing from
the fuel tank:
●Securely insert the fuel nozzle
into the fuel filler neck.
●Stop filling the tank after the fuel
nozzle automatically clicks off.

2805-4. Refueling
1Press the opener switch to
open the fuel filler door.
The fuel filler door will open within
about 10 seconds of the switch
being pressed. Before refueling is possible, a message will be shown
on the multi-information display in
the instrument clus
ter to indicate
the progress of the fuel filler door
opener.
2 Turn the fuel tank cap slowly
to open and hang it on the
back of holder on the fuel
filler door.
■If the fuel filler door cannot be
opened
Consult your Toyota dealer.
After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.
WARNING
●Do not top off the fuel tank.
NOTICE
■Refueling
●Finish refueling within 30 min-
utes. If more than 30 minutes
passes, the internal valve
closes. In this condition, fuel
may overflow during the refuel-
ing process. Press the fuel filler
door opener switch again.
●Make sure that the fuel filler
door lock is not pushed by the
fuel nozzle boot, etc. If the lock
is held, the internal valve closes
and fuel may overflow. To pre-
vent it, press the fuel filler door
opener switch again.
●Do not spill fuel during refueling.
Doing so may damage the vehi-
cle, such as causing the emis-
sion control system to operate
abnormally or damaging fuel
system components or the vehi-
cle’s painted surface.

2925-5. Using the driving support systems
●When the driver is wearing a face
mask

mouth, or shape of their face is
blocked

blocked by the frame of eye-
glasses, sunglasses, hair, etc.
●When there is a device inside the
vehicle that radiates near infrared
rays, such as a non-genuine

*: If equipped
During controlled driving, the
driver monitor camera detects
the position and direction the
driver is facing, and whether
their eyes are opened or closed.
Through this, the system deter-
mines if the driver is checking
their surroundings and if the
driver can perform driving oper-
ations.
■Warning function
In situations such as the follow-
ing, a buzzer will sound and a
message will be displayed to
warn the driver.
 When the system determines
that the driver is not paying
attention to the road or their
eyes are closed
 When the driver’s face cannot
be detected or the system
determines that the driver has
poor driving posture
