Charging the hybrid battery (traction battery)

When shift position N is selected, the hybrid battery (traction battery) will not be charged.

Thus, select P when the vehicle is stopped.

In addition, when driving in heavy traffic, use D or B.

■

Regenerative braking

The motor generator converts kinetic energy to electric energy when:

●

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.

■

Sounds and vibrations specific to a hybrid vehicle

There may be no engine sounds or vibration even though the vehicle is able to move. For

safety, apply the parking brake and make sure to shift the shift position to P when parked.

The following sounds or vibrations may occur when the hybrid system is operating and are

not a malfunction:

●

Motor sounds may be heard from the engine compartment.

●

Sounds may be heard from the hybrid battery (traction battery) behind the rear seats

when the hybrid system starts or stops.

●

Sounds may be heard from the transmission when the gasoline engine starts or stops,

when driving at low speeds, or during idling.

●

Engine sounds may be heard when accelerating sharply.

●

Sounds may be heard due to regenerative braking when the brake pedal is depressed

and accelerator is loosened.

●

Other sounds, such as motors and mechanical noises, may be heard from the brake sys-

tem when the brake pedal is depressed.

●

Vibration may be felt when the gasoline engine starts or stops.

●

Cooling fan sounds may be heard from the air intake vent on the side of rear right seat-

back.

■

Running out of fuel

When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the

vehicle with at least enough gasoline to make the low fuel level warning light go off. If there is

only a small amount of fuel, the hybrid system may not be able to start.

(The minimum amount of fuel to add to make the low fuel level warning light go out is about

3.1 gal. [11.8 L, 2.6 Imp.gal.], when the vehicle is on a level surface. This value may vary when

the vehicle is on a slope.)
