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. 578)
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. 575) 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.
Declaration of conformity
This model conforms to hydrogen emissions according to regulation
ECE100 (Battery electric vehicle safety).
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. 563)
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.

Using the mechanical key
To take out the mechanical key:
Electronic keys: Slide the
release lever and take the key
out.
Card key: Press the lock release
button and take the key out.
The mechanical key can only be
inserted in one direction, as the
key only has grooves on one
side. If the key cannot be
inserted in a lock cylinder, turn
it over and re-attempt to insert
it.
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. 630)

Card key
The mechanical key that is stored inside the card key should be used
only if a problem arises, such as when the card key does not operate
properly.
If it is difficult to take out the mechanical key, push down the lock
release button using a pen tip etc. If it is still difficult to pull it out, use a
coin etc.
The card key is not waterproof.
To store the mechanical key in the
card key, insert it while pressing the
lock release button.
If the battery cover is not installed
and the battery falls out or if the bat-
tery was removed because the key
got wet, reinstall the battery with
the positive terminal facing the
Lexus emblem.

NOTICE
Precautions for handling the card key
Do not apply excess force when inserting the mechanical key into the card
key. Doing so may damage the card key.
If the battery or card key terminals get wet, the battery may corrode and
the card key may stop working.
If the key is dropped into water, or if drinking water etc. is spilled on the
key, immediately remove the battery cover and wipe the battery and ter-
minals. (To remove the battery cover, lightly grasp and pull it.) If the bat-
tery is corroded, have any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional replace the battery.
Do not crush the battery cover or use a screwdriver to remove the battery
cover. Forcibly removing the battery cover may bend or damage the key.
If the battery cover is frequently removed, the battery cover may become
loose.
When installing the battery, make sure to check the direction of the bat-
tery.
Installing the battery in the wrong direction may cause the battery to
deplete rapidly.
The surface of the card key may be damaged, or its coating may peel off
in the following situations:
• The card key is carried together with hard objects, such as coins and
keys.
• The card key is scraped with a sharp object, such as the tip of a
mechanical pencil.
• The surface of the card key is wiped with thinner or benzene.
