2014 NISSAN LEAF battery

12. If necessary, connect the vehicle to a charging station or EVSE (Electric Vehicle Supply
Equipment) to charge the Li-ion battery. The vehicle cannot be driven unless the Li-ion battery is
charged.
NOTE:
If it is not possible to turn the LEAF system ON by following this procedure, contact a
NISSAN certified LEAF dealer immediately.
4-2 P (Park) Position Release Procedure
If you need to release the vehicle from the P (Park) position, proceed as follows. When power switch is
turned OFF or 12V battery is low, LEAF automatically shifts to P position.
NOTE: This procedure requires two (2) people.
1. To start the EV system with a booster battery, refer to 4. Jump Starting (DG–31).
2.

Turn power switch ON by pushing the power switch 2 times without pressing brake pedal.
3. Confirm parking brake is applied.
4. Close all doors and press and hold the brake pedal.
5. Place the selector lever in the N (Neutral) position.
6. Remove the following 2 fuses:
• F/L 40A PBW MTR (under hood fuse and relay box)
• METER 1 10A (in the cabin fuse box)
DG–33

Cabin Fuse Box Location
NO
TE:
Insert a screwdriver wrapped with a protective cloth (A) into the slit (1) . Pull to remove the fuse
box cover (2) . Remove the fuse with the fuse puller (3) .
7. Release the parking brake.
8. Turn the power switch OFF.
9. Release brake pedal. To avoid possible personal injury or vehicle damage, use wheel chocks or take appropriate
steps

to prevent the vehicle from rolling freely.
Be sure to firmly position wheel chocks when P (Park) position is manually released.
4-2.1 Reset Procedure 1. Install the 2 fuses removed previously.
2. Turn the power switch ON and wait 5 seconds without pressing the brake pedal. Ensure selectorlever is in the N (neutral) position.
3. If 12V battery is low voltage, please charge with battery charger.
4. Turn the power switch OFF and wait 5 seconds. UP

4-3 Storing the Vehicle
The service plug must be removed to shut down the high voltage system for storage.
Do
not store a vehicle inside a structure. Keep the vehicle away from other vehicles if the
li-ion battery is severely damaged. There is possibility of delayed fire from a severely
damaged li-ion battery.
If LEAF needs to be stored or left unattended, the high voltage system must be shut down by removing the
service plug [refer to 3-3.6 Alternate Procedure 2 (Remove Service Plug) (DG–24)] and a sign put on the
vehicle

indicating it is an electric vehicle with high voltage dangers. For example:
DG–36

5. Dismantling Information
Removal
or repair of the high voltage battery requires special tools and specific training. NISSAN strongly
recommends that only NISSAN certified LEAF dealer technicians perform these operations.
5-1 Precautions for Handling High Voltage Lithium ion (Li-ion) Battery • Because LEAF contains a high voltage (Li-ion) battery, there is the risk of electric
shock,
electric leakage, or similar accidents if the high voltage components or vehicle is
handled incorrectly. Be sure to follow the correct work procedures when performing
inspection and dismantling.
• If it is necessary to touch any of the high voltage harnesses or components you must
always
wear appropriate Personal Protective Equipment (PPE) and properly shut-down
the high voltage system by removing the service plug.
• Be sure to always wear appropriate PPE before beginning work on the high voltage
system.
• Be sure to remove the service plug in order to shut-down the high voltage system
before
performing inspection or dismantling of high voltage system harnesses and parts.
• If the vehicle is heavily damaged, for example the Li-ion battery is deformed,
broken,
or cracked; appropriate PPE must always be used at all times to avoid electrical
shock.
DG–38

• The colors of the high voltage harnesses and connectors are all orange. Orange
High
V
oltage labels are applied to the Li-ion battery and other high voltage devices. Do not
touch the Li-ion battery or other high voltage devices without always wearing appropriate
PPE.
• Clearly identify the persons responsible for high voltage work and ensure that other
persons
do not touch the vehicle. When not working, cover high voltage parts with an
insulating cover sheet and sign or similar item to prevent other persons from contacting
them.
• Be sure to put the removed service plug in your pocket and carry it with you so
another
person does not accidentally reinstall it while work is in progress.
• The high voltage battery retains high voltage at all times. Personal Protective
Equipment
(PPE) must always be worn when touching or working on high voltage
components to avoid risk of electrical shock and severe personal injury or death.
• Immediately insulate disconnected high voltage connectors and terminals with
insulated
tape.
• The vehicle contains parts that contain powerful magnets. If a person who is wearing a
pacemaker
or other medical device is close to these parts, the medical device may be
affected by the magnets. Such persons must not perform work on the vehicle.
• Because this vehicle uses components that contain high voltage and powerful
magnetism,
do not carry any metal products which may cause short circuits, or any
magnetic media (cash cards, credit cards, etc.) which may be damaged when working on
the vehicle.
• Keep removed Li-ion battery packs away from rain to avoid electric shock.
•

Do not heat removed battery packs higher than 158° F (70° C) . There is the possibility of a malfunction occurring if the vehicle is changed to READY
status while the service plug is removed.
