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 dis-
play, read the message and fol-
low the instructions.
(P. 565)
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 any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
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. 562) 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 11.8 L [3.1 gal.,
2.6 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)

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.
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 driv-
ing 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 or 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
access hole located in the luggage com-
partment. The service plug is used only
when the vehicle is serviced and is sub-
ject to high voltage.

CAUTION
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.
While depressing the brake pedal, apply the parking brake and shift the
shift position to P 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 the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into con-
tact with your skin or eyes, wash it off immediately with a large amount of
water or, if possible, boric acid solution. Seek immediate medical atten-
tion.
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 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 an electricity leakage leading to a fire. (
P. 551)
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)
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 near 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 carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the bat-
tery may be damaged. Have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.

Resetting the consumption data
Selecting on the screen will reset the average fuel con-
sumption. Selecting on the screen will reset the past
records. Selecting will confirm resetting of all the data (except
cruising range).
