Slowly release the brake pedal and check that the display on the
instrument cluster is off.
The meter display sequentially turns off after the hybrid system stops.

■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (traction battery).
●The accelerator pedal is released while driving with the shift position in D or
B.
● The brake pedal is depressed while driving with the shift position in D or \
B.
■ Gasoline engine operatio n in EV/EV auto mode
Even if there is a sufficient amount of electricity remaining in the hybrid bat-
tery (traction battery) and EV driving range is being displayed on the multi-
information display etc., EV driving (driving using only the electric motor) may
be canceled and both gasoline engine and electric motor are used depending
on the situation (EV driving will be returned to automatically after EV driving
becomes possible again).
EV driving may be canceled automatically in the following circumstances:
● When vehicle speed is more than approximately 84 mph (135 km/h).
● When power is needed temporarily, for example when the accelerator pedal
is depressed firmly or when accelerating suddenly.
*
●When the temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high speeds,
etc.
● When the temperature of the hybrid system is low.
● When the heater is switched on when the outside temperature is below
about 14°F (-10°C).
● When the windshield defogger switch is pressed.
● When the system determines that the gasoline engine needs to be started.\
The gasoline engine may also operate in circumstances other than those
listed above, depending on conditions.

NOTICE
■Notice about fuel
● For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 5.3 gal.(20 L, 4.4 Imp.gal.) of fuel every 12 months (refuel a
total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 12-month period), as this
may affect components of the fuel system or the gasoline engine.
● If the vehicle has not been refueled for a certain amount of time and it is
possible that the quality of the fuel remaining in the tank has changed, “No
new fuel has been added recently. Please refuel” is displayed on the multi-
information display when the power switch is turned to ON mode. If the
message is displayed, refuel the vehicle immediately.
