■If a warning light comes on or a warning message is displayed, or the 12 volt bat-
tery is disconnected
The hybrid system may not start. In that ca se, try to start the system again. If the
“READY” light does not come on, contact your Lexus dealer.
CAUTION
■High voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12 volt system. 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 re place 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.
●Never try to open the service plug acce ss hole located in the luggage compart-
ment. The service plug is used only when the vehicle is serviced and is subject to
high voltage.
■Nickel-metal hydride battery
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of improp-
erly, it is hazardous to the environment and there is a risk of severe burns and elec-
trical shock that may result in death or serious injury.

CAUTION
■Road accident cautions
Observe the following precautions to reduce the risk of injury.
●Pull your vehicle off the road, put the shift lever in “P”, apply the parking brake,
turn the hybrid system off.
●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 possible, boric
acid solution. Seek immediate medical attention.
●If a fire occurs in the hybrid vehicle, le ave 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 rear wheels raised. If the wheels
with the electric motor (t raction motor) are on the ground when towing, the
motor may continue to generate electricit y. This may cause an electricity leakage
leading to a fire. (
P. 4 8 2 )
●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.

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 the air vent. It may cause a short circuit and damage the hybrid bat-
tery (traction battery).
●Do not load a large amount of water such as an aquarium into the vehicle. If water
spills over the hybrid battery (tractio n battery), the battery may be damaged.

Keys
Using the mechanical keyTake 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 smart
access system with push-button
start does not operate properly,
you will need the mechanical key.
The following keys are provided with the vehicle.
Electronic keys
• Operating the smart access system with push-button start
( P. 3 5 )
• Operating the wireless
remote control function
( P. 4 7 )
Mechanical keys
Key number plate
■When required to leave a key to the vehicle with a parking attendant
Turn the trunk opener main switch OFF an d lock the glove box as circumstances
demand. ( P. 5 5 , 3 5 6 )

■Operation signals
●Doors: A buzzer sounds and the emergency flashers flash to indicate that the
doors have been locked/unlocked. (Locked: Once; Unlocked: Twice)
●Windows and moon roof: A buzzer sounds when the windows and moon roof
begin to close.
■Door lock buzzer
If a door is not fully closed, a buzzer sounds continuously if an attempt to lock the
door is made. Fully close the door to stop the buzzer, and lock the vehicle once
more.
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between key and vehicle may be affected,
preventing the smart access system with push-button start and wireless remote
control from operating properly. (Way of coping: P. 5 3 1 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wire-
less 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
• Another vehicle’s electronic key
• A wireless key that emits radio waves
• Personal computer
●If window tint with a metallic content or metallic objects are attached to the rear
window

●When the electronic key has been left within approximately 3 ft. (1 m) 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 function
( P. 47) or the mechanical key ( P. 5 3 1 )
■Electronic 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 access system with push-button start
or the wireless remote control function does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary. ( P. 4 5 4 )
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of
the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Recharging cellular phones or cordless phones
• Table lamps
