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)

■
Regenerative braking
The motor generator converts kinetic energy to electric energy when:
● The accelerator pedal is released.
● The brake pedal is depressed with the shift lever in “D” or “B”.
■ 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:
● The gasoline engine is warming up.
● The hybrid battery (traction battery) is being charged.
● The hybrid battery (traction battery) temperature is low or high.
■ 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.
■ During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybr id battery (traction battery) as
necessary.
■ When accelerating sharply
The power of the hybrid battery (traction battery) is added via
electric motor (traction motor) to that of the gasoline engine.
■ When braking (Regenerative brake)
The electric motor (traction mo tor) charges the hybrid battery
(traction battery).

■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 and you are unable to jump-start the
vehicle 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.
■ 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 from the hybrid system may be heard when the back door lid is
open.
● Sounds may be heard from the transmission when the hybrid system
starts or stops.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard from the regenerative brake when you press the
brake pedal.
● Vibration may be felt when the gasoline engine starts or stops.
● You may hear cooling fan sounds coming 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.

Note for the smart key system
● Even when the electronic key is within the effective range (detection
areas), the system may not operate properly in the following cases.
• The electronic key is too close to the window or outside door handle,
near the ground, or in a high place when the doors are locked or
unlocked.
• The electronic key is on the instrument panel, luggage cover, floor or in the glove box when the engine is started or engine switch modes are
changed.
● The doors may unlock if a large amount of water splashes on the door
handle, such as in the rain or in a car wash. (The doors will automatically
be locked after approximately 60 seconds if the doors are not opened
and closed.)
● Gripping the door handle when wearing a glove may not unlock the door.
● If the wireless remote control is used to lock the doors when the elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the entry function. (Use the wireless remote control to
unlock the doors.)
■ When the vehicle is not dr iven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2
m) of the vehicle.
■ Security feature
If a door is not opened within approximately 60 seconds after the vehicle is
unlocked, the theft deterrent system automatically locks the vehicle again.

When driving

■
Driving in the rain
● Drive carefully when it is raining, because visibility will be reduced, the
windows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be
especially slippery.
● Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road
surface, preventing the steering and brakes from operating properly.
■ Breaking in your new Toyota
To extend the life of the vehicle, the following precautions are recommended
to observe:
● For the first 180 miles (300 km):
Avoid sudden stops.
● For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
■ Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 462)
■ 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 requiring unnec-
essary engine power to recharge.
● Drive your vehicle smoothly
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the traction motor without
having to use gasoline engine power.
