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.

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.

Power (ignition) switch
Check that the parking brake is set.
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.

*: For good fuel economy and noise reduction, the D position should usually
be used.

■When shifting the shift position to P
Fully stop the vehicle and set
the parking brake, and then
press the P position switch.
When the shift position is
changed to P, the switch indica-
tor comes on.
Check that the P position is
highlighted on the shift position
indicator.
■
Shifting the shift position from P to other positions
●While depressing the brake pedal firmly, operate the shift lever. If
the shift lever is operated without depressing the brake pedal, the
buzzer will sound and the shifting operation will be disabled.
●When selecting the shift position, make sure that the shift posi-
tion has been changed to the desired position by checking the
shift position indicator provided on the instrument cluster.
●The shift position cannot be changed from P to B directly.

4504-6. Driving tips
PRIUS_OM_OM47F32E_(EE)
◆When braking
Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel economy. Check traffic reports
before leaving and avoid delays as much as possible. When driving
in a traffic jam, gently release the brake pedal to allow the vehicle to
move forward slightly while avoiding overuse of the accelerator
pedal. Doing so can help control excessive gasoline consumption.
◆Highway driving
Control and maintain the vehicle at a constant speed. Before stop-
ping at a toll booth or similar, allow plenty of time to release the
accelerator and gently apply the brakes. A greater amount of elec-
trical energy can be regenerated when slowing down.
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recircu-
lated air mode. Doing so will help to reduce the burden on the air
conditioning system and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out
until it and the interior of the vehicle are warm, it will consume fuel.
Also, fuel consumption can be improved by avoiding overuse of the
heater.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
●Have a service technician inspect the condition of the 12-volt bat-
tery.
●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.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
●Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.
