For safety
and security
◆
During normal driving
The gasoline engine is predominantly used. The electric motor (traction
motor) charges the hybrid battery (traction battery) as necessary.
◆
When accelerating sharply
When the accelerator pedal is depressed heavily, the power of the hybrid bat-
tery (traction battery) is added to that of the gasoline engine via the electric
motor (traction motor).
◆
When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a power generator,
and the hybrid battery (traction battery) is charged.
When driving with the gasoline engine stopped, a sound, which changes in
accordance with the driving speed, will be played in order to warn people nearby
of the vehicle’s approach. The sound will stop when the vehicle speed exceeds
approximately 15 mph (25 km/h).
■
Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decelera-
tion force can be obtained in conjunction with the recharging of the hybrid battery (trac-
tion battery).
●
The accelerator pedal is released while driving with the shift lever in D or S.
●
The brake pedal is depressed while driving with the shift lever in D or S.
■
EV indicator
Vehicle proximity notification system
The EV indicator comes on when the vehicle is
driven using only the electric motor (traction
motor) or the gasoline engine is stopped.
