■Display of the remaining hybrid battery (traction battery)
●The current amount of the remaining hybrid battery (traction battery) is dis-
played in the Hybrid System Indicator or the sub-screen on the main display.
(P. 227)
• The remaining battery for EV driving in EV mode is displayed in green,
and the remaining battery used in HV mode is displayed in blue.
• The amount of the remaining battery displayed decrease as the vehicle is
driven and increase when the hybrid battery (traction battery) is charged,
electrical energy is regenerated using the regenerative braking (P. 103)
or electricity is generated by the gasoline engine.
• If the remaining battery is not displayed in green, HV mode is automati-
cally selected and EV mode cannot be used. To enable EV driving,
charge the hybrid battery (traction battery). (P. 121)
●The amount of the hybrid battery (traction battery) in HV mode is automati-
cally controlled by the hybrid system. The amount of remaining hybrid battery
(traction battery) in HV mode may not reach the top line
* even if electrical
energy is regenerated using the regenerative braking (P. 103) or electricity
is generated by the gasoline engine. However, this does not indicate a mal-
function. Also, even if the display of the remaining hybrid battery (traction
battery) exceeds the top line, the display is shown in blue until the vehicle
returns to EV mode.
*: The position of the boundary line between EV mode and HV mode on the
display of the remaining hybrid battery (traction battery).
●Depending on the charging situation, when the display of the remaining
hybrid battery (traction battery) is shown during charging, charging continues
even after the display of the remaining hybrid battery (traction battery) shows
a fully charged state. However, this does not indicate a malfunction. Please
wait until charging is finished.The hybrid battery (traction battery)

◆“Eco-Diary”
The history of the average electricity consumption, air conditioning
system load ratio (“A/C Load Ratio”)
*, distance traveled and aver-
age fuel consumption can be displayed in a table according to day
(“Daily”) or month (“Monthly”) units.
*: It indicates the percentage of the electricity consumed from the hybrid
battery (traction battery) that is consumed by the air conditioning sys-
tem.

3625-1. Before driving
Prius Plug-in Hybrid_OM_OM47D72E_(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. 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 stop 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. 705

3845-2. Driving procedures
Prius Plug-in Hybrid_OM_OM47D72E_(EE)
NOTICE
■Hybrid battery (traction battery) charge
If the shift position is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery fr om discharging, avoid leaving the N
position selected for an extended period of time.
■ Situations where shift control system malfunctions are possible
If any of the following situations occurs, shift control system malfunctions
are possible.
Immediately stop the vehicle in a safe place on level ground, apply the park-
ing brake, and then contact any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
● When the warning message indicating the shift control system appears on
the multi-information display.
● The display indicates that no shift position is selected for more than a few
seconds.
■ Notes regarding shift lever and P position switch operation
Avoid repeatedly operating the shift lever and P position switch in quick suc-
cession.
The system protection function may activate and it will not be temporarily
possible to shift the shift position other than P. If this happens, please wait
for approximately 20 seconds before attempting to change the shift position
again.

Driving
Driving assist systems
◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal
is depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces.
◆VSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery
road surfaces by controlling steering performance.
◆TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when start-
ing on an uphill
To keep driving safety and performance, the following systems
operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehi-
cle.

Driving
If the vehicle gets stuck in mud, dirt or snow, the TRC system may
reduce power from the hybrid system to the wheels. Pressing to
turn the system off may make it easier for you to rock the vehicle in
order to free it.
To turn the TRC system off, quickly press and release .
The “Traction Control Turned Off” will be shown on the multi-information
display.
Press again to turn the system back on.
■ Turning off both TRC and VSC systems
To turn the TRC and VSC systems off, press and hold for more than 3
seconds while the vehicle is stopped.
The VSC OFF indicator will come on and the “Traction Control Turned Off”
will be shown on the multi-information display.*
Press again to turn the systems back on.
*: Pre-collision brake assist and pre-collision braking will also be disabled.
The PCS warning light will come on and the message will be shown on the
multi-information display. ( P. 7 1 6 )
■ When the message is displayed on the multi-information display show-
ing that TRC has been disable d even if has not been pressed
TRC is temporary deactivated. If the information continues to show, contact
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
