WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not
come on when you start the hybrid system, this could mean that these sys-
tems are not available to help protect you in an accident, which could result
in death or serious injury. Have the vehicle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer imme-
diately if this occurs.
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. 645)

◆Energy monitor
The energy monitor can be used to check the vehicle drive status,
hybrid system operation status and energy regeneration status.
When energy is flowing, an arrow appears and a bright point of light
moves to show the direction of the flow of energy. When energy is
not flowing, the bright point of light is not displayed.
Gasoline engine
Electric motor
(traction motor)
Hybrid battery
(traction battery)
Tire
Bright point of light showing
the flow of energy
As an example, all arrows are shown in the illustration, but the actual con-
tents of the display will differ.
(Display example)
●When the hybrid battery (traction battery) is being charged, the
bright point of light moves towards .
●During driving, the bright point of light moves from or (or
both depending on the situation) towards .
*
●During driving, the image of the tires rotates.
*: The display may differ depending on the driving status.

2244-1. Before driving
PRIUS_OM_OM47F32E_(EE)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When driving the vehicle
● Use engine braking (shift position B instead of shift position D) to maintain
a safe speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 2 5 4 )
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, head or other parts of their body
are not outside the vehicle.
● AWD models: Do not drive the vehicle off-road.
This is not an AWD vehicle designed fo r off-road driving. Proceed with all
due caution if it becomes unavoidable to drive off-road.
● Do not drive across river crossings or through other bodies of water.
This may cause electric/electronic components to short circuit, damage
the hybrid system or cause other serious damage to the vehicle.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid, resulting in an accident.
● After driving through a puddle, depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the
brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.

2264-1. Before driving
PRIUS_OM_OM47F32E_(EE)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as
possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle w hen the wear limits of the brake pads
and/or those of the brake discs are exceeded.
■ When the vehicle is stopped
● Do not depress the accelerator pedal unnecessarily.
If the shift position is in any position other than P or N, the vehicle may
accelerate suddenly and unexpectedly, causing an accident.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while stopped with the “READY” indicator is
illuminated, and apply the parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

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 any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer 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. In this case, transport the vehicle with both front wheels or all four
wheels lifted. ( P. 572)

2444-2. Driving procedures
PRIUS_OM_OM47F32E_(EE)
Power (ignition) switch

Firmly depress the brake pedal.
and a message will be dis-
played on the multi-information dis-
play.
When the shift position is N, the
hybrid system cannot start. Shift
the shift position to P when starting
the hybrid system. (P. 254)
Press the power switch shortly
and firmly.
When operating the power switch,
one short, firm press is enough. It
is not necessary to press and hold
the switch.
If the “READY” indicator turns on,
the hybrid system will operate nor-
mally.
Continue depressing the brake pedal until the “READY” indicator is illumi-
nated.
The hybrid system can be started from any power switch mode.
Check that the “READY” indicator is illuminated.
If the “READY” indicator changes from a flashing light to a solid light and
the buzzer sounds, the hybrid system is starting normally.
The vehicle will not move when the “READY” indicator is off.
The vehicle can move when the “READY” indicator is on even if the engine
is stopped. (The gasoline engine starts or stops automatically in accor-
dance with the state of the vehicle.)
Performing the following operations when carrying the elec-
tronic key on your person starts the hybrid system or changes
power switch modes.
