1-1. Hybrid system
Hybrid system
Your vehicle is a hybrid vehicle. It has characteristics different from
conventional vehicles. Be sure you are closely familiar with the char-
acteristics of your vehicle, and operate with care.
The hybrid system combines a gasoline engine and an electric
motor (traction motor) according to driving conditions, improving
fuel efficiency and reducing exhaust emissions.
Gasoline engine
Electric motor (traction motor)
■ When stopped/during take-off
The gasoline engine stops when the vehicle is stopped. During
take-off, the electric motor (traction motor) drives the vehicle. At
slow speeds or when traveling down a gentle slope, the engine
is stopped and the motor is used.

Before driving
■
Regenerative braking
The electric motor converts kinetic energy to electric energy when:
●The accelerator pedal is released.
● The brake pedal is depressed with the shift lever in D or R.
■ Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions:
●During gasoline engine warm-up
● During hybrid battery (traction battery) charging
● During low or high hybrid battery (traction battery) temperature
■ Charging the battery
●As the gasoline engine charges the hybrid battery (traction battery), the
battery does not need to be charged from an outside source. However, if
the vehicle is left parked for a long time the hybrid battery will slowly dis-
charge. For this reason, be sure to drive the vehicle at least once every
several months for at least 30 minutes or 10 miles (16 km). If the hybrid
battery becomes fully discharged, you are unable to jump-start the vehi-
cle with the 12-volt battery, contact your Toyota dealer.
● If the shift lever is in N, the hybrid battery (traction battery) will not be
charged. When driving in heavy traffic, operate the vehicle with the shift
lever in D to avoid discharging the battery.
■ During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybrid battery as necessary.
■ When accelerating sharply
The power of the hybrid battery (traction battery) is added via
the electric motor (traction moto r) to that of the gasoline engine.
■ When braking (regenerative braking)
The electric motor (traction mo tor) charges the hybrid battery
(traction battery).

24 1-1. Hybrid system
●To help prevent the 12-volt battery from becoming discharged, drive the
vehicle at least once a month, and operate the accessories only when
the “READY” indicator is on. When parking the vehicle, make sure the
doors and trunk are closed and all lights are turned off.
■ After the 12-volt battery has di scharged or has been changed or
removed
The gasoline engine may not stop even if the vehicle is running on the hybrid
battery (traction battery). If this continues for a few days, contact your Toyota
dealer.
■ Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. Always put the shift lever in 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 seat when the hybrid system starts or stops.
● Sounds may be heard from the transaxle when the hybrid system starts
or stops, or while the vehicle is idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to the regenerative braking when you press
the brake pedal.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vents behind the
rear seat.
■ Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.

126 2-1. Driving procedures
■For efficient use
●Put the shift lever into D when driving
In the N position, the gasoline engine operates but electricity cannot be
generated. The hybrid battery (traction battery) will be discharged requir-
ing unnecessary engine power to recharge.
● Drive your vehicle smoothly
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the electric motor (traction
motor) without having to use gasoline engine power.
● Avoid repeated acceleration
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
● Put the shift lever into P when parking
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in N for an extended period of the time may dis-
charge the hybrid battery. The vehicle cannot run if the hybrid battery is
discharged.

When driving
■
Brake actuator
The brake actuator uses brake fluid pressurized by the pump to power-assist
the brakes. If the brake actuator fails during driving, the brake system warn-
ing light comes on and the buzzer sounds continuously. In this case, the
brakes may not work properly. If they do not work well, depress the brake
pedal firmly. If the brake system warning light comes on, immediately stop
your vehicle and contact your Toyota dealer.
In the following conditions, you may hear a sound in the engine compart-
ment. This is not a malfunction.
●The driver's door is opened with the hybrid system turned off.
● The brake pedal is depressed with the hybrid system turned off.
● After the hybrid system is turned on.
● The brake pedal is depressed repeatedly with the hybrid system turned
on.
● After the hybrid system is turned off.
The brake pedal may be hard to depress or the brake pedal stroke may be
short before turning the hybrid system on. This is not a malfunction.
■ When braking the vehicle
When applying brakes, you may hear a sound coming from the motor gener-
ator.
However, this does not indicate any trouble.

128 2-1. Driving procedures
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid sys-
tem operating. 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
that could result in death or serious injury.
• 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, allowing you to depress the brake and accelerator
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 attention to pedestrians when the vehicle is pow-
ered only by the electric motor (traction motor). Because there is no
engine noise, the pedestrians may misjudge the vehicle’s movement.
● Do not drive the vehicle over or st op the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. This may
cause a fire if there is any flammable material nearby.
● Do not let the vehicle roll backwards while the shift lever is in a driving
position, or roll forward while the shift lever is in R.
Doing so may cause the hybrid system to stall or lead to poor brake and
steering performance, resulting in an accident or damage to the vehicle.\
● If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the trunk is closed. Large amounts of exhaust in the vehicle can
cause driver drowsiness and an accident, resulting in death or a serious
health hazard. Have the vehicle inspected by your Toyota dealer immedi-
ately.
