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.

• A ground fault monitor continuously monitors for high voltage leakage to the metal chassis while the
vehicle is running. If a malfunction is detected, the high voltage ECU will illuminate the hybrid system
warning light in the instrument cluster.
• The high voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flow in a
frontal collision that is sufficient enough to activate the supplemental restraint system (SRS).

Emergency Response
On arrival, first responders should follow their standard operating procedures for vehicle incidents.
Emergencies involving the Altima Hybrid may be handled like other automobiles, except as noted in these
guidelines for Extrication, Fire, Recovery, Spills, First Aid, and Submersion.
DANGER:
•
Failure to disable the high voltage electrical system before emergency response procedures are
performed may result in serious injury or death from electrical shock.
• Failure to disable the low and high voltage electrical systems before emergency response
procedures are performed may result in serious injury or death from the unintentional deployment of
the SRS.
WARNING:
• Never assume that the Altima Hybrid is shut off simply because it is quiet.
• Always observe the instrument cluster for the READY operation indicator light (green) status to
verify whether the vehicle is on or shut off. The vehicle is shut off when the READY operation
indicator light (green) is off.
• The use of personal protective equipment (PPE) su ch as insulated rubber gloves, insulated rubber
boots, and insulated rubber mats must be used when disabling the high voltage electrical system.

DANGER: •
The high voltage system may remain powered for up to 10 minutes after the vehicle is disabled.
•
To prevent serious injury or death from electrical shock avoid touching, cutting, or breaching any
orange high voltage power cable or high voltage component while the system discharges.
WARNING:
• The SRS may remain powered for up to 3 minutes after the vehicle is disabled.
• To prevent serious injury or death from unintentional SRS deployment, avoid crushing, cutting, or
breaching the SRS components.
• If the disabling procedures cannot be performed completely, proceed with caution as there is no
assurance that the high voltage electrical system, SRS, or fuel pump are disabled.
6. Remove the service disconnect by performing the following as shown:
a. Open the access panel inside the trunk to access the service disconnect.
b. Pull upward (1) on the service disconnect handle and then rotate the handle downward (2).
c. Pull outward (3) on the service disconnect handle to remove the service disconnect from the
battery.
d. Disconnect the negative (-) and positive (+) 12 volt battery cables from the 12 volt battery\
.
e. Wait 3 minutes before handling SRS system components and 10 minutes before handling high
voltage system components while the system discharges.

Jump Starting
1. Locate the HEV fusible link box located behind the engine air
cleaner.
2. Push the tab (A) in and lift up to remove the lid and expose the
remote positive (+) battery terminal (B).
DANGER:
• The engine may start at any time without warning when the ignition is on and the Hybrid System is
in the READY mode. When jump starting keep your hands, clothing, hair and tools away from
fans, belts and any other parts that can move to avoid personal injury.
• If done incorrectly, jump starting can lead to a battery explosion, resulting in severe injury or death.
It could also damage the vehicle.
• Explosive hydrogen gas is always present in the vicinity of the battery. Keep all sparks and flames
away from the battery.
• Do not allow battery fluid to come into contact with eyes, skin, clothing or painted surfaces. Battery
fluid is a corrosive sulfuric acid solution which can cause severe burns. If the fluid should come
into contact with anything, immediately flush the contacted area with water.
• Whenever working on or near a battery, always wear suitable eye protectors (for example, goggles
or industrial safety spectacles) and remove rings, metal bands, or any other jewelry. Do not lean
over the battery when jump starting.
• Do not attempt to jump start a frozen battery. It could explode and cause serious injury.
• The vehicle has an automatic engine cooling fan. It could come on at any time. Keep hands and
other objects away from it.
• Always follow the instructions below. Failure to do so could result in damage to the charging
system and cause personal injury.
