Hybrid warning message
A message is automatically displayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on the multi-information display, read
the message and follow the instructions. (P. 436)

If a warning light comes on or a warning 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 any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Electromagnetic waves
High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit 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.
Consult any authorized Toyota dealer or repairer, or another duly quali-
fied and equipped professional before installing or removing third party-
produced radio parts.
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
level warning light go off (P. 433). 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 12 L [3.2 gal., 2.7
Imp. gal.], when the vehicle is on a level surface. This value may vary when
the vehicle is on a slope.)
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.

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.

NOTICE
Hybrid battery air vent
Do not put foreign objects over 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 load a large amount of water such as an aquarium into the vehicle.
If water spills over the hybrid battery (traction battery), the battery may be
damaged.
When the rear seat belts are in use, make sure to pass them through the
guides (P. 82). Otherwise, the rear seat belts may cover the hybrid bat-
tery air vents.

Keys
Using the mechanical key
Take out the mechanical key.
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. 474)
The following keys are provided with the vehicle.
Electronic keys
• Operating the smart entry &
start system (if equipped)
(P. 44)
• Operating the push button

Operation signals
The emergency flashers flash to indicate that the doors have been locked/
unlocked. (Locked: Once; Unlocked: Twice)
Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situ-
ations, the communication between the electronic key and the vehicle may
be affected, preventing the smart entry & start system and wireless remote
control from operating properly: (Ways of coping: P. 474)
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 has come into contact with, or is covered by a
metallic object
When multiple electronic keys are in the vicinity
When carrying or using the electronic key together with the following
devices that emit radio waves

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
When the electronic key has been left within approximately 1 m (3 ft.) of
the vehicle for 10 minutes or more
The system will resume operation when...
The vehicle is locked using the door handle lock switch.
The vehicle is locked/unlocked using the wireless remote control func-
tion. (P. 70)
The vehicle is locked/unlocked using the mechanical key. (P. 474)
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.)
