Lamp Name Icon Description
READY Indicator (Green)
This lamp is on when the high voltage system is powered
up and the vehicle is ready to drive.
Master Warning Lamp
(Orange or Red)
This lamp is on when another warning lamp or message is
displayed in the instrument cluster.
Hybrid System Warning
Lamp *1 (Orange)
This lamp is on or blinking when:
• Malfunction has occurred in the high voltage system and/or
• High voltage leak to vehicle chassis and/or
• Emergency shut-off system has been activated. The
shut-off system activates in the following conditions:
– Front and side collisions in which the air bags are deployed.
– Certain rear collisions.
– Certain high voltage system malfunctions.
*1: When this lamp is ON, the READY Indicator will turn OFF. DG–10

2-4 High Voltage Safety Measures
Circuit insulation The high voltage positive (+) and negative (-) circuits are insulatedfrom the metal chassis.
Reducing the risk of electrocution The high voltage components and harnesses have insulated cases or orange-colored coverings which provide insulation and easy identification.
The high voltage battery case is electrically connected to the vehicle ground.
This connection helps protect the vehicle occupants and vehicle dismantlers
from high voltage electrical shock.
Identification The high voltage components are labeled “WARNING” similar to label shown below. All high voltage harnesses are coated in orange.

2-5 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.
• Positive and negative high voltage power cables are connected to the high voltage battery and arecontrolled 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. However, it can take
approximately ten (10) minutes for the high voltage capacitor to fully discharge.
• The high voltage system and high voltage capacitor may remain powered for up to
approximately 10 minutes after the vehicle is shut off. 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.
• The high voltage battery retains high voltage at all times. 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.
• 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 HPCM (hybrid powertrain control module) will
illuminate the hybrid system warning lamp
in the instrument cluster.

6. Remove the shift lock cover (A) using a suitable tool.
7. Push down the shift lock (B) as shown in the illustration.
8. Push the shift selector button (C) and move the shiftselector to Neutral (N) position (D) while holding down
the shift lock.
NOTE:
DO NOT press accelerator or foot brake after
moving the shift selector to the Neutral (N)
position. Otherwise Li-ion battery will start to be charged.
NOTE:
The engine must not be running at this time. If the engine has restarted, repeat the
previous steps.
9. Release the parking brake.
10. Unbuckle the seat belt and open the driver door. The READY
indicator should remain ON
and the engine should not be running.
11. Turn ON electric devices such as headlamps, A/C (set to the coldest temperature) and rear window defogger to discharge the high voltage battery. Allow approximately 15 minutes to
discharge. Discharge is complete when the READY
indicator (B) (green) turns OFF, the
hybrid system warning indicator (C) (orange) turns ON and the message display indicates “Li-ion
battery low”.
