CAUTION
High voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12-volt sys-
tem. DC and AC high voltage is very dangerous and can cause severe burns
and electric shock that may result in death or serious injury.
Never touch, disassemble, remove or replace the high voltage parts,
cables and their connectors.
The hybrid system will become hot after starting as the system uses high
voltage. Be careful of both the high voltage and the high temperature, and
always obey the caution labels attached to the vehicle.
Hybrid battery (traction battery)
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of
improperly, it is hazardous to the environment and there is a risk of severe
burns and electrical shock that may result in death or serious injury.
Never try to open the service plug
access hole located in the luggage
compartment. The service plug is used
only when the vehicle is serviced and is
subject to high voltage.
Do not subject the service plug to
strong impacts. Also, avoid splashing
large amount of water onto the luggage
compartment, for example while in a
high-pressure car wash.

CAUTION
Emergency shut off system
Carefully check to see if there are exposed high voltage parts or cables.
Never touch the parts or cables. (P. 34)
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.
Road accident cautions
If your vehicle is involved in an accident, observe the following precautions
to reduce the risk of injury.
Stop the vehicle in a safe place to prevent subsequent accidents. While
depressing the brake pedal, apply the parking brake and push the P posi-
tion switch to stop the hybrid system. Then, slowly release the brake
pedal.
Do not touch the high voltage parts, cables and 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 it 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 pos-
sible, 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 the front wheels raised. If the
wheels with the electric motor (traction motor) are on the ground when
towing, the motor may continue to generate electricity. This may cause an
electricity leakage leading to a fire. (P. 423)
Nickel-metal hydride battery
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of
improperly, it is hazardous to the environment and there is a risk of severe
burns and electrical shock that may result in death or serious injury.

Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle and electronic key batteries from discharging.
When the entry function has not been used for 2 weeks or more

Key battery depletion
The standard battery life is 1 to 2 years. (The battery becomes depleted
even if the electronic key is not used.) If the smart entry & start system or
the wireless remote control function does not operate, or the detection
area becomes smaller, the battery may be depleted. Replace the battery
when necessary. (P. 397)
If the battery becomes low, an alarm will sound in the cabin when the
hybrid system stops. (P. 441)
To avoid serious deterioration, do not leave the electronic key within 1 m
(3 ft.) of the following electrical appliances that produce a magnetic field.
•TVs
• Personal computers
• Recharging cellular phones or cordless phones
• Table lamps
To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention may not func-
tion.)

CAUTION
Caution regarding interference with electronic devices
People with implanted pacemakers or cardiac defibrillators should main-
tain a reasonable distance between themselves and the smart entry &
start system antennas. (P. 46)
The radio waves may affect the operation of such devices. If necessary,
the entry function can be disabled. Ask any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional for details,
such as the frequency of radio waves and timing of emitting the radio
waves. Then, consult your doctor to see if you should disable the entry
function.
User of any electrical medical device other than implanted pacemakers
and implanted cardiac defibrillators should consult the manufacturer of the
device for information about its operation under the influence of radio
waves.
Radio waves could have unexpected effects on the operation of such
medical devices.
Ask any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional for details for disabling the entry function.

CAUTION
When the vehicle is parked
Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following.
• Gas may leak from a cigarette lighter or spray can, and may lead to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and
plastic material of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the
interior of the vehicle, and may also cause a short circuit in the vehi-
cle's electrical components.
Always apply the parking brake, push the P position switch, turn the hybrid
system off and lock the vehicle.
Do not leave the vehicle unattended while the hybrid system is operating.
Do not touch the exhaust pipe while the hybrid system is operating or
immediately after turning the hybrid system off.
Doing so may cause burns.
Do not leave the hybrid system operating in an area with snow build-up, or
where it is snowing. If snowbanks build up around the vehicle while the
hybrid system is operating, exhaust gases may collect and enter the vehi-
cle. This may lead to death or a serious health hazard.
When parking the vehicle
Be sure to firmly apply the parking brake and push the P position switch.
Failure to do so may cause the vehicle to move or the vehicle may acceler-
ate suddenly, resulting in an accident if the accelerator pedal is accidentally
depressed.

NOTICE
If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually press the brake pedal to slow down the vehicle.
It may be difficult to control your vehicle.
The vehicle will make abnormal sounds.
The vehicle will behave abnormally.
Information on what to do in case of a flat tire. (P. 447, 459)
When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle.
Engine stalling
Short in electrical components
Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional check the following.
Brake function
Changes in quantity and quality of oil and fluid used for the engine, hybrid
system, transmission, etc.
Lubricant condition for the bearings and suspension joints (where possi-
ble) and the function of all joints, bearings, etc.
As flooding may damage components involved in P position control, the
parking lock may jam in the locked position.
