If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
connected
The hybrid system may not start. In this 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. 5 6 7 )
go off. If there is only a small amount of fu el, the hybrid system may not be able to start.
(The standard amount of fuel is about 2.7 gal. [10.1 L, 2.2 Imp.gal.], when the vehicle is on
a level surface. This value may vary when the vehicle is on a slope. Add extra fuel when
the vehicle is inclined.) ■
Electromagnetic waves ●
High voltage parts and cables on hybrid ve hicles incorporate electromagnetic shield-
ing, and therefore emit approximately the same amount of electromagnetic waves as
conventional gasoline powered vehicl es 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 condi-
tions.

High voltage precautions
This 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 replace the high voltage parts, cables or their
connectors. ●
The hybrid system will become hot after star ting as the system uses high voltage. Be
careful of both the high voltage and the hi gh temperature, and always obey the warn-
ing labels attached to the vehicle. ●
Never try to open the service plug access
hole located underneath the rear seats. The
service plug is used only when the vehicle is
serviced and is subject to high voltage.

Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury: ●
Pull your vehicle off the road, shift the shift lever to P, apply the parking brake, 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 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 el ectric fires. Using even a small amount of
water may be dangerous. ●
If your vehicle needs to be towed, do so with front wheels (2WD models) or four
wheels (AWD models) raised. If the wheels connected to the electric motor (traction
motor) are on the ground when towing, the motor may continue to generate electric-
ity. This may cause a fire. (  P. 5 5 8 )●
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) ●
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, th e following may occur, resulting in death
or serious injury:
• The hybrid battery may be illegally dispos ed 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 elec-
trolyte leakage may occur.
When reselling or handing over your ve hicle, the possibility of an accident is
extremely high because the person receiving 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 sh op. If the hybrid bat-
tery is not disposed of properly, it may caus e electric shock that can result in death or
serious injury.
NOTICE ■
Hybrid battery (traction battery) air intake and discharge vents ●
Do not place objects that will block the air intake vents. The hybrid battery (traction
battery) may have a reduction in hybrid batt ery (traction battery) output as well as be
damaged. ●
Clean the air intake and discharge vents regularly to prevent the hybrid battery (trac-
tion battery) from overheating. ●
Do not get water or foreign materials in either the air intake and discharge vents 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 your Lexus dealer.

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 includin g harmful carbon monoxide (CO) may collect and enter
the vehicle. This may lead to death or a serious health hazard.
NOTICE ■
The multi-information disp lay at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal information
display. At extremely low temperatures, th e information display monitor may respond
slowly, and display changes may be delayed. ■
During setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid syst em is operating while
setting up the display features.

play projector. If the projector gets wet, elec-
trical malfunctions may result. ●
Do not place anything on or put stickers onto
the head-up display projector.
Doing so could interrupt head-up display
indications. ●
Do not touch the inside of the head-up display
projector or thrust sharp edges or the like into
the projector.
Doing so could cause mechanical malfunc-
tions.
