headlamp NISSAN ALTIMA HYBRID 2010 L32A / 4.G First Responders Guide

Foreword

Nissan released the Nissan Altima Hybrid in North America in January of 2007. The Nissan Altima Hybrid runs
on conventional gasoline and a traction motor. The basic vehicle systems and features of the Altima Hybrid are
the same as those of the conventional Altima, except where noted in this guide. This First Responder’s Guide
was published to help educate and assist first responders in the safe handling of the Altima Hybrid and its
technology.

A high voltage battery is used to power the traction motor, generator, electric air conditioning compressor,
voltage converter, and inverter unit. A separate 12 volt battery is used to power other electrical devices such as
the radio, horn, headlamps, and instrument cluster gauges. A number of safeguards have been designed to
ensure that the high voltage Nickel Metal Hydride (Ni-MH) battery is kept safe and secure in the event of an
accident.

The Altima Hybrid utilizes both low and high voltage systems:

Low voltage system

• A 12 volt DC negative chassis ground body electrical system

High voltage system

• A 245 volt DC high voltage battery
• A harness that carries high voltage between the high voltage battery, converter, inverter unit, transaxle
and electric air conditioning compressor
• A converter which converts 245 volts DC to 42 volts DC for the electric power steering (EPS) system
• A converter which converts 245 volts DC for charging the 12 volt battery
• An inverter unit which delivers up to 650 volts AC to the transaxle
• A transaxle which houses a traction motor and generator
• A 245 volt DC, electric motor driven electric air conditioning compressor

High voltage electrical safety is an important factor in the emergency handling of the Altima Hybrid. It is
important to recognize and understand the disabling procedures and warnings throughout this guide.
Additional topics in this guide include:
• Nissan Altima Hybrid identification
• Hybrid system component locations and descriptions
• Extrication, fire, recovery, and additional emergency response information
• Roadside assistance information






This First Responders Guide is intended to assist first responders in the safe handling of a Nissan Altima
Hybrid. The information contained in this guide is somewhat simplified and intended to be used as a
technical reference. Please refer to the Nissan Service Manual for information related to vehicle repair.
