Hybrid Synergy Drive Operation - Toyota Prius Manual

H ybrid Synergy Drive Operation (2012 Model)
Once the READY indicator is illuminated in the instrument cluster, the
vehicle may be driven. However, the gasoline engine does not idle like a
typical automobile and will start and stop automatically. It is important
to recognize and understand the READY indicator provided in the
instrument cluster. When lit, it informs the driver that the vehicle is on
and operational even though the gasoline engine may be off and the
engine compartment is silent.
Vehicle Operation
•
With the Prius Plug-in hybrid, the gasoline engine may stop and start at any
time while the READY indicator is on.
•
Never assume that the vehicle is shut off just because the engine is off.
Always look for the READY indicator status. The vehicle is shut off when
the READY indicator and instrument cluster lights are off.
•
The vehicle may be powered by:
1. The electric motor only.
2. A combination of both the electric motor and the gasoline engine.
•
The vehicle computer determines the mode in which the vehicle operates in
order to improve fuel economy and reduce emissions. The Prius Plug-in
hybrid features EV (Electric Vehicle) mode, a mode that is automatically
selected when the HV battery is charged using an external power source.
Power and ECO (Economy) modes are driver selectable.
1. EV Mode: When activated, and certain conditions have been met,
the vehicle operates with the electric motor powered by the HV
battery.
2. ECO Mode: When activated, this mode helps enhance fuel
economy on trips that involve frequent braking and acceleration.
3. Power Mode: Optimizes acceleration feel by increasing the power
output more quickly at the beginning of accelerator pedal
operation.
Vehicle Proximity Notification System
A new feature on the Prius Plug-in hybrid is the vehicle proximity notification
system that emits a sound when the vehicle is driven using only the electric
motor at speeds less than 15 mph. The sound is intended to notify pedestrians
that the vehicle is approaching.
