■If a warning light comes on, 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 your Lexus dealer.
■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
(  P. 496) go off. 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 3.4 gal. [13 L, 2.8 Imp. gal.], when the vehicle is on a level sur-
face. This value may vary when the vehicle is on a slope.)
■Electromagnetic waves
●High voltage parts and cables on the hybr id vehicles incorporate electromagnetic
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.
■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
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
●Pull your vehicle off the road, apply the parking brake, shift the shift lever to P, and
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 the flui d 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 imme diate 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 four wheels raised. If the wheels con-
nected to the electric motor (traction mo tor) are on the ground when towing, the
motor may continue to generate electricity. This may cause an electricity leakage
leading to a fire. ( P. 4 8 6 )
●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.

CAUTION
■Hybrid battery (traction battery)
●Your vehicle contains a sealed nickel-metal hydride battery. Never resell, hand
over or modify the hybrid battery. To prevent accidents, hybrid batteries that have
been removed from a disposed vehicle are collected through Lexus dealer. Do
not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting in
death or serious injury:
• The hybrid battery may be illegally disp osed of or dumped, and it is hazardous
to the environment or someone may touch a high voltage part, resulting in an
electric shock.
• The hybrid battery is intended to be used exclusively with your hybrid vehicle. If the hybrid battery is used outside of your vehicle or modified in any way,
accidents such as electric shock, heat generation, smoke generation, an
explosion and electrolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident is
extremely high because the person rece iving the vehicle may not be aware of
these dangers.
●If your vehicle is disposed of without the hybrid battery having been removed,
there is a danger of serious electric shock if high voltage parts, cables and their
connectors are touched. In the event that your vehicle must be disposed of, the
hybrid battery must be disposed of by your Lexus dealer or a qualified service
shop. If the hybrid battery is not disposed of properly, it may cause electric shock
that can result in death or serious injury.
■Emergency shut off system
●Carefully check to see if there are expose d high voltage parts or cables. Never
touch the parts or cables. ( P. 8 1 )
●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 vents
●Do not put foreign objects over the air vents. The hybrid battery (traction battery)
may overheat and be damaged.
●Clean the air vents regularly to prevent the hybrid battery (traction battery) from
overheating.
●Do not wet or allow foreign substances to enter the air vents as this may cause a
short circuit and damage the h ybrid 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 (t raction battery), the battery may be dam-
aged. Have the vehicle inspected by your Lexus dealer.

■System maintenance
The vehicle has a maintenance-free type alarm system.
■Items to check before locking the vehicle
To prevent unexpected triggering of the alarm and vehicle theft, make sure of the fol-
lowing:
●Nobody is in the vehicle.
●The windows and moon roof are closed before the alarm is set.
●No valuables or other personal items are left in the vehicle.
■Triggering of the alarm
The alarm may be triggered in the following situations:
(Stopping the alarm deactivates the alarm system.)
■Alarm-operated door lock
●When the alarm is operating, the doors ar e locked automatically to prevent intrud-
ers.
●Do not leave the key inside the vehicle when the alarm is operating, and make sure
the key is not inside the vehicle when rech arging or replacing the 12-volt battery.
●A person inside the vehicle opens a door,
the trunk or hood.
●The 12-volt battery is recharged or replaced
when the vehicle is locked. (P. 5 2 8 )
NOTICE
■To ensure the system operates correctly
Do not modify or remove the system. If modified or removed, the proper operation
of the system cannot be guaranteed.

●Charge area indicates regeneration* status. Regenerated energy will be used to
charge the battery.
*: When used in this manual, “regeneration” refers to the conversion of energy cre-
ated by the movement of the vehicle into electrical energy.
■ECO lamp and SPORT lamp
●When all of the following conditions are satisfied and Eco-friendly driving is being
performed, ECO lamp (blue) will illuminate. (ECO lamp will become brighter the

ation exceeds Zone of Eco driving, ECO lamp turns off. ( P. 103) However, when
Eco drive mode is selected, while the vehicle is stopped or the acceleration
exceeds Zone of Eco driving, ECO lamp does not turn off.):

CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, caus-
ing rapid and excessive engine braking and possibly an accident resulting in death
or injury.
■Cautions during setting up the display
As the hybrid system needs to be operating during setting up the display, ensure
that the vehicle is parked in a place with adequate ventilation. In a closed area such
as a garage, exhaust gases including harmful carbon monoxide (CO) may collect
and enter the vehicle. This may lead to death or a serious health hazard.
NOTICE
■During setting up the display
To prevent 12-volt battery discharge, ensu re that the hybrid system is operating
while setting up the display features.
