CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other
drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that dis-
tracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you,
your occupants or others.
■ General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.

■
When in EV mode
Driving using only the electric motor (traction motor) is possible
(excluding certain situations, su ch as when accelerating sud-
denly), but if the amou nt of charge remaining in the hybrid bat-
tery (traction battery) becomes low, EV mode will be canceled.
In order to prolong EV mode driving, observe the following:
● Check the EV driving range using the energy monitor or
Hybrid System Indicator.
● Avoid sudden acceleration and sudden deceleration, and be
sure to drive smoothly.
If you repeatedly accelerate, the hybrid battery (traction bat-
tery) charge will deplete quickly. Also, the gasoline engine will
start, depending on acceleration or the vehicle speed.
● Restrain your speed as much as possible. The EV driving
range will reduce considerably at high speeds.

■When in HV mode
The vehicle can be used in the same way as a standard hybrid
vehicle.
In HV mode, controls are primarily carried out as follows in
accordance with the driving conditions.
●The gasoline engine stops when the vehicle is stopped.
● During start off, the electric motor (traction motor) drives the
vehicle.
● During normal driving, the gasoline engine and electric motor
(traction motor) are controlled effectively, and the vehicle is
driven with optimum fuel efficienc y. Also, when necessary, the
electric motor (traction motor) operates as an electrical gener-
ator to charge the hybrid battery (traction battery).
● When the accelerator pedal is depressed heavily, drive force
from both the gasoline engine an d the electric motor (traction
motor) is used to accelerate.
■ When braking (regenerative braking)
The electric motor (traction mo tor) charges the hybrid battery
(traction battery).
The EV driving range can be extended by actively using this
regenerative braking to store el ectricity in the hybrid battery
(traction battery).
Moreover, as fuel consumption is also reduced when in HV
mode, the regenerative braking sy stem can be used effectively.

■
When continually using EV mode only
After driving for approximately 124 miles (200 km) with the gasoline engine
off, the gasoline engine may start for a short amount of time in order to pro-
tect the system.
■ 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
● When the temperature of the hybrid battery (traction battery) is high or
low
● During hybrid battery (traction battery) charging
● When the heater is switched on
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.
■ If the vehicle is not used for a long time
The 12-volt battery may discharge. In this event, charge the 12-volt battery.
(P. 594)
In order to prevent the hybrid battery (traction battery) from becoming
extremely low in charge, start the hybrid system at least once every 2 or 3
months, and turn the “POWER” switch off after the gasoline engine has
stopped automatically. (If the gasoline engine does not start up even after
approximately 10 seconds have passed since the “READY” indicator came
on, the “POWER” switch can be turned to OFF without any further action.)

■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.
● The brake system operation sound heard from the front of the vehicle
when the driver’s door is opened.
● 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 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 you press the
brake pedal or release the accelerator pedal.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent. ( P. 45)
● The operation sound of the air conditioning system (air conditioning com-
pressor, blower motor).

Hybrid battery (traction battery) air vents
There are air intake vents on the
side of the rear right seatback
and on the front corner of the left
rear seat cushion for the purpose
of cooling the hybrid battery
(traction battery). If the vents
become blocked, the hybrid bat-
tery (traction battery) may over-
heat, leading to a reduction in
hybrid battery (traction battery)
output.
Emergency shut off system When a certain level of impact is detected by the impact sensor, the
emergency shut off syst em blocks off the high voltage current and
stops the fuel pump to minimize t he risk of electrocution and fuel
leakage. If the emergency shut off sy stem activates, your vehicle will
not restart. To restart the hybrid system, contact your Toyota dealer.
