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 emergency
responders 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
WARNING/AVERTISSEMENT
To avoid serious injury, keep clear engine parts at all times. Engine may start at any time if the start switch and the the READY lamps
on the instrument 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 d e bord sont éteints
(OFF) avant d'entreprendre tout travail à I'intérieur du compartiment moteur. Le moteur peut démarrer à tout moment si le contacteur
d'allumage est à la position ON et que les témoins READY du tableau de bord sont allumés. Assurez-vous que les deux
témoins sont éteints avant de travailler dans le compartiment moteur. Reportez-vous au manuel du conducteur.

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.
• 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) .

2-6 High Voltage Circuit Shut-Off System
This vehicle is equipped with a system to shut off the current from the high voltage battery by the following methods:
Service plug Positioned in the center area of the high voltage battery, this plug shuts offthe output of high voltage when manually removed.
System main relays
(located in the high
voltage battery) Controlled by the ignition switch, these relays are powered by the 12-volt
system and shut off high voltage from the high voltage battery.
Emergency shut-offsystem In the case of a collision (front and side collisions in which the air bags are
deployed, certain rear collisions) or certain system malfunctions this system
is designed to shut off the high voltage from the high voltage battery.
2-7 Preventing Electrical Shock 1. If it is necessary to touch any of the high voltage harnesses or components, always wearappropriate Personal Protective Equipment (PPE) (refer to
3-1 Preparation Items (FRG–17)) .
Shut off the high voltage system by referring to
3-3.1 High Voltage System Shut-Down
Procedure (FRG–20)
.
2. To avoid the risk of electrocution, NEVER touch the inside of the high voltage battery with bare hands after shutting off the high voltage system. The high voltage battery maintains charge even
though the high voltage system is shut down. PPE must always be worn when touching or
working on high voltage components.
3. Cover damaged high voltage components with insulated tape.
2-8 Emergency Medical Equipment
The high voltage system should not interfere with emergency medical equipment which must be used in or
near the vehicle at an accident scene.

3. Emergency Response Steps
DANGER
•Failure to properly shut down the high voltage electrical system before the
Emergency Response 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.
•
If it is necessary to touch any of the high voltage harnesses or components you
must always wear appropriate PPE to avoid electrical shock. PPE must always beworn
when touching or working on high voltage components. Shut downthe high voltage
system by following the steps outlined in
3-3.1 High Voltage System Shut-Down
Procedure (FRG–20)
Wait approximately ten (10) minutes for complete discharge of
the high voltage capacitor after the high voltage system has been shut down.
• NEVER assume the Q50 HYBRID is shut OFF simply because it is quiet.
• If the READY
indicator is ON thehigh voltage system is active.
• If possible, besure to check the READY
indicator on the instrument cluster and
verify that theREADY
indicatoris OFF and the high voltage system is stopped.
