• 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 front, side or certain rear collisions that are sufficient enough to activate the supplemental
restraint system (SRS) . Trunk
