WARNING
■Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the
seat belt will not securely hold the child restraint system, which could cause
death or serious injury to the child or other passengers in the event of sud-
den braking, sudden swerving or an accident.
■ To correctly attach a child restraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects
around the anchors and that the seat belt is not caught behind the child
restraint system. Make sure the child restraint system is securely attached,
or it may cause death or serious injury to the child or other passengers in
the event of sudden braking, sudden swerving or an accident.

Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics different
from conventional vehicles. Be sure you are closely familiar with
the characteristics of your vehicle, and operate with care.
The hybrid system combines the use of a gasoline engine and
an electric motor (traction moto r) according to driving condi-
tions, improving fuel efficien cy and reducing exhaust emis-
sions.

■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 lever in D or S.
● The brake pedal is depressed while driving with the shift lever in D or S.
■ EV indicator
■ 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
● When the temperature of the hybrid battery (traction battery) is high or low
● When the heater is switched on
■ Charging the hybrid battery (traction battery)
●As the gasoline engine charges the hybrid battery (traction battery), the bat-
tery 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 discharge.
For this reason, be sure to drive the vehicle at least once every few 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. Always shift the shift lever in P when the vehicle is stopped. When
driving in heavy traffic, operate the vehicle with the shift lever in D or S to
avoid discharging the hybrid battery (traction battery).
● 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 are
closed and all lights are turned off.
The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.

Hybrid system precautions
Take care when handling the hybrid system, as it contains a high
voltage system (about 650 V at maximum) as well as parts that
become extremely hot when the hybrid system is operating.
Obey the caution labels attached to the vehicle.

■If a warning light comes on, a warn ing message is displayed, or the 12-
volt battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact your Toyota dealer.
■ When refueling, the fuel filler door may take a few moments to open
As part of emission system operation, it may take up to 10 seconds for the
fuel filler door to automatically release after the opener switch is pressed.
Before refueling is possible, a message will be shown on the multi-informa-
tion display. ( P. 259)
■ 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 le\
vel
warning light ( P. 459) 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 2.6 gal. [9.7 L, 2.1 Imp.
gal.], when the vehicle is on a level surface. This value may vary when the
vehicle is on a slope.)
■ Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore em it approximately the same amount of
electromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.

WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
● Pull your vehicle off the road, shift the shift lever to P, apply the parking
brake, and turn the hybrid system off.
● Do not touch the high voltage parts, cables or connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● If a fluid leak occurs, do not touch the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into contact
with your skin or eyes, wash it off immediately with a large amount of water
or, if possible, boric acid solution. Seek immediate medical attention.
● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with all four wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause a fire. (
P. 452)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.
