Instrument cluster
PRIUS +_OM_OM47B16E_(EE)■
Remaining hybrid battery (tract ion battery) charge display
The charge amount of the hybrid battery (traction battery) is automatically
controlled by the hybrid system. For this reason, even if electricity is recov-
ered via the regenerative braking, or el ectricity is generated via the gasoline
engine, the displayed hybrid battery (traction battery) charge amount may not
reach the highest level (level 8). However, this does not indicate a malfunc-
tion.
■ Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help
improve fuel efficiency and reduce exhaust emissions etc.
■ Brightness of the instrument panel light
If the headlight switch is turned to ON while the surrounding area is dark, the
instrument cluster lights will dim.
■ When disconnecting and reconnect ing 12-volt battery terminals
The fuel consumption display and average vehicle speed 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. 444)
■ 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.

1924-1. Before driving
PRIUS +_OM_OM47B16E_(EE)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY”
indicator is illuminated. This prevents the vehicle from creeping.
■ When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a diffi- culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● The driver should pay extra attention to pedestrians when the vehicle is
powered only by the electric motor (traction motor). As there is no engine
noise, the pedestrians may misjudge the vehicle’s movement.
● Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.
● During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or braking control,
however, power assist to the steering will be lost. This will make it more
difficult to steer smoothly, so you should pull over and stop the vehicle as
soon as it is safe to do so. In the event of an emergency, such as if it
becomes impossible to stop the vehicle in the normal way: →P. 369
● 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. 209)
● 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, heads or other parts of their body
are not outside the vehicle.

Driving
PRIUS +_OM_OM47B16E_(EE)
Power (ignition) switch
Check that the parking brake is set.
Firmly depress the brake pedal.
Check that the power switch indicator turns green. If the indicator does not
turn green, the hybrid system cannot be started.
When the shift position is N, the hybrid system cannot start. Shift the shift
position to P when starting the hybrid system. (→P. 209)
Press the power switch.
If the “READY” indicator turns on,
the hybrid system will operate nor-
mally.
Continue depressing the brake
pedal until the “READY” indicator
is illuminated.
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.

Driving
PRIUS +_OM_OM47B16E_(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.
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.
