High Voltage Safety

High Voltage Safety System


The high voltage safety system is intended to help keep vehicle occupants and emergency responders safe
from high voltage electricity.

• A high voltage fuse provides short circuit protection inside the high voltage battery.

• The high voltage safety system is insulated from the metal chassis so there is no possibility of electric
shock when touching the chassis.

• Positive and negative high voltage power cables are connected to the high voltage battery and are
controlled by normally open system main relays (SMR1 and SMR2). When the vehicle is shut off, the
relays stop electrical flow from leaving the high voltage battery.

- 12 -

• 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).

1. Supplemental curtain side-impact air bags 2. Supplemental seat-mounted side-
impact air bags 3. Supplemental front-impact air
bags
4. Crash zone sensor 5. Air bag diagnosis sensor unit (control unit) 6. Seat belt pre-tensioners
7. Satellite sensors

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.

NOTE:
Repositioning the power seats, operating the power door locks and operating the power trunk release must be
done prior to 12 volt battery disconnection.

Automatic Door Locks (Not Applicable to 2007 or 2008 Model Years)

This vehicle is equipped with an automatic door lock system. All door
locks will unlock automatically when the ignition switch is placed in the
OFF position or when the power door lock switch (located on the front LH
or RH door trim panel) is manually operated as shown.






Extrication


1. Immobilize the vehicle a. Move the shift lever to the P (Park) position.

b. Shut the vehicle OFF by pressing the push-button ignition
switch.
c. Chock the wheels.
d. Set the parking brake.





2. Remove the Intelligent Key (1) from the key port (located on the lower
LH corner of the instrument panel). Keep it at least 3.3 feet (1 meter)
away from the vehicle.









3. Stabilize the vehicle a. Crib at four points directly under the front and rear pillars. Do
not place cribbing under the high voltage harness, exhaust
system or fuel system.

4. Open the trunk using one of the following methods: • Intelligent Key button:
Push and hold the trunk release button for longer than 0.5 second
to open the trunk.

NOTE:
The trunk release button on the Intelligent Key will not operate
when the ignition switch is in the ON position or when the trunk
cancel switch (located in the glove box) is in the OFF position.



• Interior trunk release switch:
The trunk switch is located on the left side of the
instrument panel. To open the trunk, push the switch downward.

NOTE:
The interior trunk release switch will not operate when the trunk
cancel switch (located in the glove box) is in the OFF position.




• Secondary trunk release:
a. Remove the door key from the Intelligent Key as
shown.






b. Fold down the rear center seat armrest/cup holder
to reveal the trunk compartment access panel. Use
the door key to unlock and open the access panel.
Pull the trunk release handle (1).






5. Disconnect the negative (-) 12 volt battery cable by performing the following:
a. Open the access panel (1) inside the lower right-hand side of
the trunk to access the negative (-) battery cable (2).

b. Disconnect the negative (-) 12 volt battery cable (2) from the 12
volt battery (3).

- 18 -
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.

Alternative High Voltage System Shut Down Procedure
NOTE:
If the service disconnect procedure cannot be performed, the following alternative shut down procedure is
acceptable.

A. Locate the fuse/fusible link box (1) under the hood near the driver
side strut tower (2).
• : Vehicle Front










B. Remove the fuse/fusible link box cover and remove the IGCT 50
amp fusible link (1) from the fuse/fusible link box (2). If the correct fuse
cannot be recognized, pull all the fuses in the fuse/fusible link box.

7. Accessing the occupants
• Glass removal:
Use normal glass removal procedures as required.

• SRS awareness:
First responders need to be cautious when working in proximity of undeployed air bags and seat

belt pre-tensioners. Front dual stage air bags automatically ignite both stages within a fraction of a
second.

• Door removal/displacement:
Doors can be removed by conventional rescue tools such as hand, electric, and hydraulic tools. In
certain situations, it may be easier to pry back the vehicle body to expose and unbolt the hinges.

• Roof removal:
The Altima Hybrid contains curtain air bags. If undeployed, it is not recommended to remove or to
displace the roof. As an alternative, remove the roof panel between the two roof rails.

• Instrument panel displacement:
The Altima Hybrid contains curtain air bags. Do not remove or displace the roof during an instrument panel displacement to avoid cutting into undeployed air bags or inflators. As an
alternative, instrument panel displacement may be performed using a modified instrument panel
roll.

• Rescue lift bags:
First responders should not place cribbing or rescue lift bags under the high voltage power cables,
exhaust system, or fuel system.

NOTE:
Repositioning the power seats must be done prior to 12 volt battery disconnection.

• Repositioning the seats:
The power seat control can be located as shown.
Moving the switch forward or backward will slide
the seat forward or backward to the desired position. Move the recline switch backward until the
desired position is obtained. To bring the seatback forward again, move the switch forward while
moving forward.
