• 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). 2-6 High Voltage Circuit Shut-Off System This vehicle is equipped with a system to shut off the current from the Li-ion battery by the following methods: Service plug Positioned in the right rear area of the Li-ion battery, this plug shuts off the output of high voltage when manually removed. Controlled by the ignition switch, these relays are powered by the 12V sysSystem main relays (located in the high voltage tem and shut off high voltage from the Li-ion battery. battery) Emergency shut-off system 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 Li-ion battery. 2-7 Preventing Electrical Shock 1. If it is necessary to touch any of the high voltage harnesses or components, always wear appropriate Personal Protective Equipment (PPE) [refer to 3-1 Preparation Items (FRG-18)]. 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 Li-ion battery with bare hands after shutting off the high voltage system. The Li-ion 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.
