◆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 are not displayed.

As an example, all arrows are shown in the illustration, but the actual con-
tents of the display will differ.

●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 .

■Hybrid battery (tract ion battery) status
● The display changes in 8 levels according to the remaining charge amount
of the hybrid battery (traction battery).
● The hybrid battery (traction battery) status is also displayed on the following
screen, but the contents of the display are the same.
• Sub-screen of the main display ( →P. 112)
• Hybrid System Indicator ( →P. 11 9 )
• Head-up display (if equipped) ( →P. 146)
● 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 electricity 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 mal-
function.
■ Remaining charge amount warning of hybrid battery (traction battery)
●The buzzer sounds intermittently when the hybrid battery (traction battery)
remains without charging while the shift position is in N, or the remaining
charge amount drops below a certain level.
If the remaining charge amount drops further, the buzzer sounds continu-
ously.
● When a warning message is shown on the multi-information display and the
buzzer sounds, follow the instructions displayed on the screen to perform
troubleshooting.Low

“ECO Accelerator Guidance”
A blue zone is displayed in the
Eco area which can be used as
a reference operation range for
using the accelerator pedal
according to driving conditions
such as starting off and cruis-
ing.
The “ECO Accelerator Guid-
ance” display changes accord-
ing to the driving status, such as
when starting off or cruising.
It is easier to drive in an Eco-friendly manner by driving according to the
display showing the accelerator pedal operations and staying within the
“ECO Accelerator Guidance” range. ( →P. 215)
The “ECO Accelerator Guidance” function can be turned off in the

■Flow of energy and display details
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 are not displayed.
● The display when the engine is operating is in blue while the
engine is being warmed up and yellow afterwards.
● The arrow from the engine to the motor and tires is displayed in
red.
● The arrow indicating energy consumption is displayed in yellow
and the arrow indicating energy regeneration or charging is dis-
played in green. Also, the hybr id battery (traction battery)
changes color accordingly.

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 ac\
cel-
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. Even
though the vehicle is equipped with the vehicle proximity notification sys-
tem, drive with care as pedestrians in the vicinity may still not notice the
vehicle if the surrounding area is noisy.
● Do not drive the vehicle over or st op the vehicle near flammable materials
such as leaves, paper or rags.
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. 665

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. 241)
● 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.
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has h\
igh-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.
■ 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.

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.
● Do not shift the shift position to R while the vehicle is moving forward\
.
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.
● Moving 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.
