In November 2007, Lexus will release the Lexus
LS 600hL petrol-electric hybrid vehicle in
Australia. Except where noted in this guide,
basic vehicle systems and features for the

conventional, non-hybrid, Lexus LS 460.
This LS 600hL Emergency Response Guide has
been published to educate and assist
emergency responders in the safe handling
of the LS 600hL hybrid technology.
High voltage electricity powers the electric
motor, generator, A/C compressor, and
inverter/converter. All other automotive
electrical devices such as the horn, radio, and
gauges are powered from a separate 12 Volt
battery. Numerous safeguards have been
designed into the LS 600hL to help ensure the
high voltage, approximately 288 Volts, Nickel
Metal Hydride (NiMH) Hybrid Vehicle (HV)
battery pack is kept safe and secure in an
accident.
The LS 600hL utilises the following electrical
systems:
• Maximum 650 Volts AC
• Nominal 288 Volts DC
• Maximum 46 Volts AC / DC
