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.
2-4.1 Warning Labels
To avoid serious injury, keep clear of engine parts at all times. Engine may start at any time if

the start switch and the READY lamps on the instrum ent panel are "ON". Make sure both
lamps are "OFF" before working in the engine compartment. See Owners Manual.

Pour éviter des blessures graves, assurez-vous que les témoins START SWITCH et READY

dans le tableau de bord sont éteints (OFF) avant d' entreprendre tout travail a l' intérieur du
compartiment moteur. Le moteur peut démarrer a tout moment si le contacteur d' allumage
est a la position ON et que les témoins READY du ta bleau de bord sont allumés. Assurez-vous
que les deux témonins sont éteints avant de travailler dans le compartiment moteur.

2-5 High Voltage Safety System
he 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.
• The high voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flow in a front, side or certain rear collisions that are sufficient enough to activate the supplemental
restraint system (SRS) .

9. Release the parking brake.
10. 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 and
the hybrid system warning indicator (C) (orange) turns ON.
11. Press the ignition switch (A) to turn the system OFF.
Please contact following number if the vehicle could not be discharged. • 1-800-662-6200 (US) or 1-800-361-4792 (Canada)
• Hours of operation are 8am-5pm (Monday-Friday) Eastern, Central and Pacific time zones.
3-4 How to Handle a Damaged Vehicle
3-4.1 High Voltage System Shut-Down Procedure
Any of the following procedures can shut down the high voltage system. The dismantling operation canonly
begin after shutting down the high voltage system. If the vehicle is heavily damaged, for example the high
voltage battery is deformed, broken or cracked, appropriate PPE must always be used and the high voltage
battery and high voltage components must not be touched.
DANGER
•Failure to properly shut down the high voltage system before the dismantling
procedures are performed will result in serious injury or death from electrical shock.
To prevent serious injury or death, NEVER touch high voltage harnesses or components
without always wearing appropriate Personal Protective Equipment (PPE) . PPE must
always be worn when touching or working on high voltage components.
•When contact with high voltage components or high voltage harnesses is
unavoidable, or when there is risk of such contact, you must always wear appropriate
PPE. PPE must always be worn when touching or working on high voltage components.
