CAUTION
Road accident cautions
If your vehicle is involved in an accident, observe the following precautions
to reduce the risk of death or serious injury:
Stop the vehicle in a safe place to prevent subsequent accidents.
While depressing the brake pedal, apply the parking brake, shift the shift
position to P and turn the hybrid system off. 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.
Do not touch the battery if liquid is leaking from or adhering to it.
If electrolyte (carbonic-based organic electrolyte) from the hybrid battery
(traction battery) comes into contact with the eyes or skin, it could cause
blindness or skin wounds. In the unlikely event that it comes into contact
with the eyes or skin, wash it off immediately with a large amount of water,
and seek immediate medical attention.
If electrolyte is leaking from the hybrid battery (traction battery), do not
approach the vehicle.
Even in the unlikely event that the hybrid battery (traction battery) is dam-
aged, the internal construction of the battery will prevent a large amount of
electrolyte from leaking out. However, any electrolyte that does leak out
will give off an acidic vapor. This vapor is an irritant to skin and eyes and
could cause acute poisoning if inhaled.
Do not bring burning or high-temperature items close to the electrolyte.
The electrolyte may ignite and cause a fire.
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.

CAUTION
If your vehicle needs to be towed, do so with front 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. 461)
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.
Hybrid battery (traction battery)
Your vehicle contains a sealed lithium-ion 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.
NOTICE
Hybrid battery (traction battery) air vent
Do not put foreign objects near the air vent. The hybrid battery (traction
battery) may overheat and be damaged.
Clean the air vent regularly to prevent the hybrid battery (traction battery)
from overheating.
Do not wet or allow foreign substances to enter the air vent as this may
cause a short circuit and damage the hybrid battery (traction battery).
Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.

PRIUS +_OM_OM47821E_(EE)
Security feature
If a door is not opened within approximately 30 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again.
Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic key battery and the 12-volt battery from being discharged while the
vehicle is not in operation for a long time.
In the following situations, the smart entry & start system may take some
time to unlock the doors.
• The electronic key has been left in an area of approximately 2 m (6 ft.)
of the outside of the vehicle for 10 minutes or longer.
• The smart entry & start system has not been used for 5 days or longer.
If the smart entry & start system has not been used for 14 days or longer,
the doors cannot be unlocked at any doors except the driver’s door. In
this case, take hold of the driver’s door handle, or use the wireless
remote control or the mechanical key, to unlock the doors.

Conditions affecting operation
The smart entry & start system, wireless remote control and immobilizer sys-
tem use weak radio waves. In the following situations, the communication
between the electronic key and the vehicle may be affected, preventing the
smart entry & start system, wireless remote control and immobilizer system
from operating properly. (Ways of coping: P. 519)
When the electronic key battery is depleted
Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication devices
When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
When other wireless key (that emit radio waves) is being used nearby
When carrying the electronic key together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio
waves
• Personal computers or personal digital assistants (PDAs)
