Foreword
The 2
nd
generation Toyota Highlander gasoline-electric hybrid
Emergency Response Guide has been revised to include the changes of
the 2011 model year vehicle. These changes include minor updates to
the gasoline engine, vehicle exterior and interior. The important change
affecting the emergency responder is the relocation of the 12 Volt
auxiliary battery from the engine compartment to the rear cargo area.
The 2
nd
generation Highlander hybrid introduced in May 2007
continues to share the basic vehicle systems and features of the
conventional, non-hybrid, Highlander.
High voltage electricity powers the electric motors, generator, A/C
compressor, and inverter/converter. All other automotive electrical
devices such as the headlights, radio, and gauges are powered from a
separate 12 Volt auxiliary battery. Numerous safeguards have been
designed into the Highlander hybrid 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.
The Highlander hybrid utilizes the following electrical systems:
Maximum 650 Volts AC
Nominal 288 Volts DC
Nominal 12 Volts DC
2
nd

Supplemental Restraint System (SRS) – dual stage frontal airbags,
front seat mounted side airbags, side curtain airbags, front seatbelt
pretensioners, and a driver side knee airbag.
High voltage electrical safety remains an important factor in the
emergency handling of the Highlander Hybrid Synergy Drive. It is
important to recognize and understand the disabling procedures and
warnings throughout the guide.
Additional topics in the guide include:
Toyota Highlander hybrid identification.
Major Hybrid Synergy Drive component locations and descriptions.
