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, shift the
shift lever to P, apply the parking brake, and turn the hybrid system off.
( P. 148)
● Do not touch the high voltage parts, cables or connectors. Carefully check
to see if there are exposed high voltage parts or cables.
● 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 the 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. 425)
● 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 and contact your Toyota dealer.
■ 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.

tery (traction battery) may overheat and be damaged.
● Clean the air vent regularly to prevent the hybrid battery (traction battery)
from overheating.
● Do not wet 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.

Remaining hybrid battery (tract ion battery) charge display
The charge amount of the hybrid battery (traction battery) is automatically
controlled by the hybrid system. For this reason, even if electricity is recov-
ered via the regenerative braking, or electricity is generated via the gasoline
engine, the displayed hybrid battery (traction battery) charge amount may
not reach the highest level (level 8). However, this does not indicate a mal-
function.
■ Resetting the consumption data (Display Audio System)
Selecting “Clear” on the “Trip Information” screen will reset the fuel con-
sumption and the regenerated energy for the past 15 minutes. Selecting
“Yes” on the following screen will confirm resetting of all the data.

Before driving
Using the mechanical key (vehicles with a smart key system)
To take out the mechanical key,
slide the release lever and take
the key out.
The mechanical key can only be
inserted in one direction, as the
key only has grooves on one
side. If the key cannot be inserted
in a lock cylinder, turn it over and
re-attempt to insert it.
After using the mechanical key,
store it in the electronic key. Carry
the mechanical key together with
the electronic key. If the electronic
key battery is depleted or the
entry function does not operate
properly, you will need the
mechanical key.
(P. 473)
■ Key number plate
Keep the plate in a safe place such as your wallet, not in the vehicle. In the
event that a key (without a smart key system) or mechanical key (with a
smart key system) is lost, a new key can be made by your Toyota dealer
using the key number plate. ( P. 472)
■ When riding in an aircraft
When bringing a key with wireless remote control function onto an aircra\
ft,
make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc., ensure that the buttons
are not likely to be pressed accidentally. Pressing a button may cause the
key to emit radio waves that could interfere with the operation of the a\
ircraft.

Conditions affecting operation
The smart key system uses weak radio waves. In the following situations,
the communication between the electronic key and the vehicle may be
affected, preventing the smart key system, wireless remote control and
immobilizer system from operating properly.
(Ways of coping: P. 473)
● 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 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 keys (that emit radio waves) are being used nearby
● When carrying the electronic key together with the following devices that
emit radio waves
• A portable radio, cellular phone, cordless phone or other wireless com-
munication device
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)

56 1-3. Opening, closing and locking the doors
■Notes for the entry function
●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 or floor, in the door pockets or glove box when the hybrid system is started or
“POWER” switch modes are changed.
● Do not exit the vehicle with the electronic key placed on the instrument
panel or near the door pockets. Depending on the radio wave reception
conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the elec-
tronic key inside the vehicle.
● As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone.
● Whether or not the electronic key is inside the vehicle, the hybrid system
could be started if the electronic key is near the window.
● 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 when the electronic key is
within the effective range. (The door will automatically be locked after
approximately 60 seconds if the doors are not opened and closed.)
● The lock and unlock sensors may not work properly if they come into
contact with ice, snow, mud, etc. Clean the sensors and attempt to oper-
ate them again.
● 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. (Using the wireless remote control to
unlock the doors may resume the function.)
● If the door handle becomes wet while the electronic key is within the
effective range, the door may lock and unlock repeatedly. In that case,
follow the following correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart key system. ( P. 54)
