PRIUS PRIME_OM_OM47D71U_(U)The vehicle is equipped with sophisticated computers that will record certain
data, such as:
• Engine speed/Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving assist systems
• Images from the cameras
Your vehicle is equipped with cameras. Contact your Toyota dealer for the
location of recording cameras.
• Hybrid battery (traction battery) status
The recorded data varies according to the vehicle grade level and options
with which it is equipped.
These computers do not record conversations or sounds, and only record

2-1. Plug-in hybrid system
■If the vehicle is not used for a long time
●The 12-volt battery may discharge. In this event, charge the 12-volt battery.
(P. 607)
In order to prevent the hybrid battery (traction battery) from becoming
extremely low in charge, charge the hybrid battery (traction battery) from
external power source or start the hybrid system at least once every 2 or 3
months, and turn the power switch off after the gasoline engine has
stopped automatically. (If the gasoline engine does not start up even after
approximately 10 seconds have passed since the “READY” indicator came
on, the power switch can be turned to off without any further action.)
●When the vehicle is left with the charging cable connected, the electricity
consumption amount of the 12-volt battery increases due to controls, such
as the system checking, operating. When the charging cable is not needed,
immediately remove it from the vehicle.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to
move with the “READY” indicator is illuminated. For safety, apply the parking
brake and make sure to shift the shift position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction.
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) when the
hybrid system starts or stops.
●Relay operating sounds such as a snap or soft clank will be emitted from the
hybrid battery (traction battery), behind the rear seats, when the hybrid sys-
tem is started or stopped.
●Sounds from the hybrid system may be heard when the back door is open.
●Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is
depressed or as the accelerator pedal is released.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vents. (P. 99)
■Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be diffi-
cult for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of
the vehicle, it may be more difficult to hear from the rear of the vehicle com-
pared to the front.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When shifting the shift position
●Do not let the vehicle roll backward while a forward driving position is
selected, or roll forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.
●Do not shift the shift position to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
●<00270052000300510052005700030056004b004c0049005700030057004b004800030056004b004c004900570003005300520056004c0057004c00520051000300570052000300350003005a004b004c004f004800030057004b0048000300590048004b00

Doing so can damage the transmission and may result in a loss of vehicle
control.
●Do not shift the shift position to a driving position while the vehicle is mov-
ing backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
●Changing the shift position to N while the vehicle is moving will disengage
the hybrid system. Engine braking is not available with the hybrid system
disengaged.
●Be careful not to change the shift position with the accelerator pedal
depressed.
Changing the shift position to any position other than P or N may lead to
unexpected rapid acceleration of the vehicle that may cause an accident
and result in death or serious injury.
After changing the shift position, make sure to confirm the current shift
position displayed on the shift position indicator inside the meter.

NOTICE
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, hybrid
transmission, etc.
●Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
If the shift control system is damaged by flooding, it may not be possible to
shift the shift position to P, or from P to other positions. When the shift posi-
tion cannot be changed from P to any other position, the front wheels will
lock, and you will be unable to tow the vehicle with the front wheels on the
ground, as the front wheels may be locked. In this case, transport the vehi-
cle with both front wheels or all four wheels lifted. (P. 667)

Release the shift lever after each shifting operation to allow it to return to
the position.
When shifting from P to N, D or R, from D to R, or from R to D, ensure that
the brake pedal is being depressed and the vehicle is stationary.
Shift position indicator
The current shift position is highlighted.
When any shift position other than D or B is selected, the arrow toward B
and B position indicator disappear from the shift position indicator.
When selecting the shift position, make sure that the shift position has
been changed to the desired position by checking the shift position
indicator provided on the instrument cluster.
Shifting the shift lever

When shifting to the D or R, move the shift lever along the shift
gate.
To shift to the N, slide the shift lever to the left and hold it. The shift
position will change to N.
To shift to the B, pull the shift lever down. Shifting to B is only pos-
sible when shift position D is selected.

●Install tire chains on the front tires only. Do not install tire chains on the rear
tires.
●Install tire chains on front tires as tightly as possible. Retighten chains after
driving 1/4 - 1/2 mile (0.5 - 1.0 km).
●<002c0051005600570044004f004f00030057004c0055004800030046004b0044004c00510056000300490052004f004f0052005a004c0051004a00030057004b00480003004c0051005600570055005800460057004c005200510056000300530055005200

■Consumption of fuel and electricity
In cold temperatures, resistance of the parts of a vehicle (transmission, tires,
etc.) generally increases, resulting in increase of energy consumption. As a
result, fuel economy is likely to decrease.
Consumption of fuel and electricity of this vehicle is also likely to become
worse in cold temperatures.
WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
●Use snow tires on all, not just some wheels.
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
●Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
●Do not use LTA (Lane Tracing Assist).
■When parking the vehicle
When parking the vehicle without applying the parking brake, make sure to
chock the wheels. If you do not chock the wheels, the vehicle may move
unexpectedly, possibly resulting in an accident.
