Lexus RX400h Emergency Response Guide
Hybrid 2006 Model
Emergency Response Guide
FOREWORD
• A high voltage Electric Power Steering (EPS)
assist motor rated at 42-Volts.
In October 2006, Lexus released the Lexus
RX400h petrol-electric hybrid vehicle in
Australia. Except where noted in this guide,
basic vehicle systems and features for the
RX400h are the same as those on the
conventional, non-hybrid, Lexus RX330/350.
To educate and assist emergency responders in
the safe handling of the RX400h hybrid
technology, Lexus published this RX400h
Emergency Response Guide.
• Body electrical system rated at 12-Volts
negative chassis ground.
• RX400h is only availbale in Australia as a
four wheel drive (4WD).
• 4WD models include an additional 650-Volt
electric motor to drive the rear wheels.
• Supplemental Restraint System (SRS) - dual
stage frontal airbags, driver knee airbag,
front seat mounted side airbags, side curtain
airbags, and front seat belt pretensioners.
High voltage electricity powers the electric
motors, generator, inverter/converter, and
power steering. All other automotive electrical
devices such as the headlights, radio, and
gauges are powered from a separate 12-Volt
battery. Numerous safeguards have been
designed into the RX400h to help ensure the
high voltage, approximately 288-Volt, Nickel
Metal Hydride (NiMH) Hybrid Vehicle (HV)
battery pack is kept safe and secure in an
accident.
High voltage electrical safety is an important
factor in the emergency handling of the
RX400h Hybrid Synergy Drive system. It is
important to recognise and understand the
disabling procedures and warnings throughout
the guide.
Additional topics contained in the guide
include:
• Lexus RX400h identification.

ABOUT THE RX400h
The RX400h sedan is the first 4WD petrol-electric
hybrid vehicle for Lexus in Australia. Hybrid
Synergy Drive means that the vehicle contains a
petrol engine and an electric motor for power. Two
energy sources are stored on board the vehicle:
1. Petrol stored in the fuel tank for the
petrol engine.
2. Electricity stored in a high voltage Hybrid
Vehicle (HV) battery pack for the electric motor.
The result of combining these two power sources is
improved fuel economy and reduced emissions.
The petrol engine also powers an electric generator
to recharge the battery pack; unlike a pure all
electric vehicle, the RX400h never needs to be
recharged from an external electric power source.
Depending on the driving conditions one or both
sources are used to power the vehicle.
The following illustration demonstrates how the
RX400h operates in various driving modes.
❶
During light acceleration at low speeds, the
vehicle is powered by the electric motor.
The petrol engine is shut off.
❷
During normal driving, the vehicle is powered
mainly by the petrol engine. The petrol engine
also powers the generator to recharge the
battery pack.
❸
During full acceleration, such as climbing a hill,
both the petrol engine and the electric motor
power the vehicle.
❹
During deceleration, such as when braking, the
vehicle regenerates the kinetic energy from the
rear wheels to produce electricity that recharges
the battery pack.
❺
While the vehicle is stopped, the petrol engine
and electric motor are off, however the vehicle
remains on and operational.

HYBRID SYNERGY DRIVE OPERATION
Once the READY indicator is illuminated in the
instrument cluster, the vehicle may be driven.
However, the petrol engine does not idle like a
typical vehicle and will start and stop automatically.
It is important to recognise and understand the
READY indicator provided in the instrument
cluster. When lit, it informs the driver that the
vehicle is on and operational even though the
petrol engine may be off and the engine
compartment is silent.
Instrument cluster READY Indicator
Vehicle Operation
• With the RX400h, the petrol engine may stop
and start at any time while the READY indicator
is on.
• Never assume that the vehicle is shut off just
because the engine is off. Always look for the
READY indicator status. The vehicle is shut off
when the READY indicator is off.
• The vehicle may be powered by:
1. The electric motor only.
2. The petrol engine only.
3. A combination of both the electric motor
and the petrol engine.
• The vehicle computer determines the mode in
which the vehicle operates to improve fuel
economy and reduce emissions. The driver
cannot manually select the mode.

HYBRID VEHICLE (HV) BATTERY PACK
AND AUXILIARY BATTERY
The RX400h contains a next generation high
voltage, Hybrid Vehicle (HV) battery pack and a low
voltage auxiliary battery. The HV battery pack
contains non-spillable, sealed Nickel Metal Hydride
(NiMH) battery modules and the auxiliary battery is
a typical automotive lead-acid type.
HV Battery Pack
288-Volt HV Battery Pack
• The HV battery pack is enclosed in a metal case
and is rigidly mounted to the cabin area floor
pan cross member under the rear seat. The
metal case is isolated from high voltage and
concealed by a cover in the cabin area.
• The HV battery pack consists of 30 low voltage
(9.6-Volt) NiMH battery modules connected in
series to produce approximately 288-Volts. Each
NiMH battery module is non-spillable and
sealed in a metal case.
• The electrolyte used in the NiMH battery
module is an alkaline of potassium and sodium
hydroxide. The electrolyte is absorbed into the
battery cell plates and will form a gel that will
not normally leak, even in a collision.
HV Battery Pack Mounted in
Cabin Area
• In the unlikely event the battery pack is
overcharged, the modules vent gases directly
outside the vehicle through a vent hose.

High Voltage Safety System – Vehicle Shut
Off (READY-OFF)
The HV battery pack powers the high voltage
electrical system with DC electricity. Positive and
negative high voltage power cables are routed
from the battery pack, under the vehicle floor pan,
to the inverter/converter. The inverter/converter
contains a circuit that boosts the HV battery voltage
from 288 to 650-Volts DC. The inverter creates
3-phase AC to power the motors. A set of 3 power
cables is routed from the inverter to each high
voltage motor (electric motor, electric generator,
A/C compressor, and 4WD rear motor). Occupants
in the vehicle and emergency responders are
separated from high voltage electricity by the
following system:

WARNING:
•
Power remains in the high voltage
electrical system for 5 minutes after the
HV battery pack is shut off.
•
Never touch, cut, or open any orange
high voltage power cable or high voltage
component.
•
Failure to follow these warnings can
cause severe burns and electric shock
that may result in death or serious injury.
• A high voltage fuse ❶ provides short circuit
protection in the HV battery pack.
• Positive and negative high voltage power cables
❷ connected to the HV battery pack are
controlled by 12-Volt normally open relays ❸.
When the vehicle is shut off, the relays stop
electricity flow from the HV battery pack.
• Both positive and negative power cables ❷ are
isolated from the metal chassis, so there is
no possibility of shock by touching the
metal chassis.
• A ground fault monitor ❹ continuously
monitors for high voltage leakage to the metal
chassis while the vehicle is running. If a
malfunction is detected, the vehicle computer ❹
will illuminate the master warning light
in the instrument cluster and indicate
“CHECK HYBRID SYSTEM” on the
Multi-information Display.
• The HV battery pack relays will automatically
open to stop electricity flow in a collision
sufficient to activate the SRS or rear
collision sensors.
The HV battery pack also powers a 288-Volt DC to
42-Volt DC converter for the assist motor in the
electric power steering (EPS). This DC-DC converter
is located under the cargo area ❶. Both positive
and negative 42-Volt cables ❷ are contained within
plastic yellow sheathing and are isolated from the
metal vehicle chassis.
NOTE:
42-Volt DC has a higher arc potential than 12-Volt DC.

EMERGENCY RESPONSE
Fire
Approach and extinguish a fire using proper vehicle fire
fighting practices.
•
Extinguishing Agent
Water has been proven to be a suitable extinguishing agent.
•
Initial Fire Attack
Perform a fast, aggressive fire attack.
Divert the runoff from entering watershed areas.
Attack teams may not be able to identify a RX400h until the
fire has been knocked down and overhaul operations
have commenced.
•
Fire in the HV Battery Pack
Should a fire occur in the NiMH HV battery pack, attack crews
should utilise a water stream or fog pattern to extinguish
any fire within the luggage compartment except for the
HV battery pack.
When allowed to burn themselves out, the RX400h NiMH battery
modules burn rapidly and can quickly be reduced to ashes except
for the metal.
Offensive Fire Attack
Normally flooding the NiMH HV battery pack with copious
amounts of water at a safe distance will effectively control the HV
battery pack fire by cooling the adjacent NiMH battery modules
to a point below their ignition temperature. The remaining
modules on fire, if not extinguished by the water, will burn
themselves out.
However, flooding the RX400h HV battery pack is not
recommended due to battery design and forward location
preventing the responder from properly applying water through
the available vent openings safely. It is recommended that the
incident commander allow the RX400h HV battery pack to burn
itself out.
WARNING:
• Potassium hydroxide and sodium hydroxide are key ingredients in the
NiMH battery module electrolyte.
• The modules are contained within a metal case and access is limited to
duct openings under the rear seat.
• The HV battery cover should never be breached or removed under any
circumstances including fire.
• Failure to follow these warnings can cause severe burns and electric shock
that may result in death or serious injury.
– 14 –
EMERGENCY RESPONSE
Defensive Fire Attack
If the decision has been made to fight the fire using a defensive
attack, the fire attack crew should pull back a safe distance and
allow the NiMH battery modules to burn themselves out. During
this defensive operation, fire crews may utilise a water stream or
fog pattern to protect exposures or to control the path of smoke.
Overhaul
During overhaul, immobilise and disable the vehicle if not already
done. See illustrations on page 11.
•
Immobilise Vehicle
Chock wheels and set the parking brake.
Move the shift lever to the P (Park) position.
•
Disable Vehicle
Performing any one of the following two procedures will shut
the vehicle off and disable the HV battery pack, SRS, and petrol
fuel pump.
Procedure #1
Turn the ignition key off.
1. Remove the key and place on dash.
2. If the key cannot be removed, disconnect the 12-Volt
auxiliary battery in the engine compartment.
Procedure #2 (alternate if ignition key is inaccessible)
1. Disconnect the 12-Volt auxiliary battery in the engine
compartment.
2. Remove engine compartment covers.
3. Remove the fuse box cover.
4. Remove the IGCT No. 4 Fuse (10A Red coloured) in the
engine compartment junction block. When in doubt, pull all
four fuses in the fuse block.
WARNING:
• After disabling the vehicle, power is maintained for 90 seconds in the SRS
system and 5 minutes in the high voltage electrical system.
• If either of the disabling steps above cannot be performed, proceed with
caution as there is no assurance that the high voltage electrical system,
SRS, or fuel pump are disabled.
• Never touch, cut, or open any orange high voltage power cable or high
voltage component.
• Failure to follow these warnings may result in death or serious injury from
the sudden deployment of the SRS or severe burns and electric shock

EMERGENCY RESPONSE
Recovery/Recycling of NiMH HV
Battery Pack
Clean up of the HV battery pack can be accomplished by the vehicle
recovery crew without further concern of runoff or spillage.
For information regarding recycling of the HV battery pack, contact the
nearest Lexus dealer or Lexus Australia.
Spills
The RX400h contains the same common automotive fluids used in
other non-hybrid Lexus vehicles, with the exception of NiMH
electrolyte used in the HV battery pack. The NiMH battery electrolyte is
a caustic alkaline (pH 13.5) that is damaging to human tissues.
The electrolyte, however, is absorbed in the cell plates and will not
normally spill or leak out even if a battery module is cracked.
A catastrophic crash that would breach both the metal battery pack
case and the plastic battery module would be a rare occurrence.
Similar to the use of baking soda to neutralise a lead-acid battery
electrolyte spill, a dilute boric acid solution or vinegar can be used to
neutralise a NiMH battery electrolyte spill.
In an emergency, check the Material Safety Data Sheets (MSDS)
on page 20.
•
Handle NiMH electrolyte spills using the following
Personal Protective Equipment (PPE):
Splash shield or safety goggles. Fold down helmet shields are
not acceptable for acid or electrolyte spills.
Rubber, latex or nitrile gloves.
Apron suitable for alkaline.
Rubber boots.
•
Neutralise NiMH Electrolyte
Use a boric acid solution or vinegar.
Boric acid solution - 800 grams boric acid to 20 litres water.
– 16 –
EMERGENCY RESPONSE
First Aid
Emergency responders may not be familiar with a NiMH electrolyte
exposure when rendering aid to a patient. Exposure to the electrolyte
is unlikely except in a catastrophic crash or through improper
handling. Utilise the following guidelines in the event of exposure.
WARNING:
The NIMH battery electrolyte is a caustic alkaline (pH 13.5) that is damaging
to human tissues. Wear proper personal protective equipment to avoid
coming into contact with the electrolyte.
•
Wear Personal Protective Equipment (PPE)
Splash shield or safety goggles. Fold down helmet shields are
not acceptable for acid or electrolyte spills.
Rubber, latex or nitrile gloves.
Apron suitable for alkaline.
Rubber boots.
•
Absorption
Perform gross decontamination by removing affected clothing
and properly disposing of the garments.
Rinse the affected areas with water for 20 minutes.
Transport patients to the nearest emergency medical care facility.
•
Inhalation in Non-Fire Situations
No toxic gases are emitted under normal conditions.
•
Inhalation in Fire Situations
Toxic gases are given off as by-products of combustion.
All responders in the Hot Zone should wear the proper PPE for
fire fighting including SCBA.
Move a patient from the hazardous environment to a safe area
and administer oxygen.
Transport patients to the nearest emergency medical care facility.
•
Ingestion
Do not induce vomiting.
Allow a patient to drink large quantities of water to dilute
electrolyte (Never give water to an unconscious person).
If vomiting occurs spontaneously, keep the patient’s head
lowered and forward to reduce the risk of asphyxiation.
Transport patients to the nearest emergency medical care facility.
Submersion
When fully or partially submersed a RX400h can be safely handled by
following these recommendations:
• Remove the vehicle from the water.
• Drain the water from the vehicle if possible.
• Follow the immobilising and disabling procedures on page 11.

5. Fire Fighting Measures
(1) Firefighting measures
and extinguisher
(1) Use powder-type ABC extinguisher.
(2) When corrosive gas could be generated in the event of fire fighting,
use appropriate breathing apparatus.
(3) Extinguishing a fire with a large amount of water may be an
effective method.
However, this should be considered as a supplementary means.
If there are no readily available large amounts of water, use dry sand
instead; as the application of only a small amount of water may
temporarily act as an accelerant and affect the fire adversely while the
hydrogen storage alloy is burning.
(4) Remove the flammable materials from the fire.
(5) If fire occurs nearby to batteries, move them to a safe place.
(2) Possibility of fire and explosion
(1) Fire may occur when:
Short circuit-induced arcing occurs.
A large current is applied to a module or a cell.
(2) Explosion may occur when:
The battery is contained in a hermetic container, since oxygen and/or
hydrogen may be generated by the battery. The battery itself will not
explode in normal conditions.
(3) Fire and explosion may occur when:
The battery is over-charged or over-discharged. The battery is over
100 deg C.
The battery is in a hermetic container with an ignition source nearby
and overcharge or overdischarge occurs.
6. Measures for electrolyte leakage
When the alkaline electrolyte leaks from battery.
(1) Wipe off with a towel.
(2) Keep away from flames.
(3) Protective glasses and rubber gloves should be worn.
7. Handling and Storage
(1) No short circuit
Short circuit should be prevented since heat generation and/or fire
may result.
(2) No disassembly and reconstruction
The battery should not be disassembled and/or reconstructed for the
following reasons:
• If a cell is disassembled, alkaline electrolyte may leak.
• If a module is disassembled, short circuiting may occur.
• If a module is disassembled, cells will be damaged and alkaline
electrolyte may leak.
(3) No over-charge or over-discharge
Battery should not be over-charged or over-discharged to prevent possible
oxygen and/or hydrogen generation.
(4) No usage in hermetic container
Battery should not be used in a hermetic container since the container may
explode due to gas generated from the battery.
8. Exposure Control
When alkaline electrolyte leakage from the battery occurs, necessary
action should be taken as follows:
(1) Acceptable concentration
Not specified in Japanese Industrial Hygienic association and ACGIH.
(2) Facilities
(1) Ventilation should be considered. Limited exhaust device or other
ventilation device should be used.
(2) Exhaust system or exhaust hole is required when the battery is used
in a container.
