KNOW YOUR VEHICLE

HIGH VOLTAGE BATTERY
Your vehicle is equipped with a Lithium-ion high-voltage battery that is used to power the electric powertrain systems and the 12 Volt vehicle electrical system. The high-voltage battery is located under the rear seat. Lithium-ion batteries provide the following benefits:

• Lithium-ion batteries are much lighter than other types of rechargeable batteries of the same size.
• Lithium-ion batteries hold their charge; they only lose approximately three percent of their charge per month.
• Lithium-ion batteries have no memory, which means that you do not have to completely discharge them before recharging, as with some other batteries.
• Lithium-ion batteries can be recharged and discharged thousands of times.

High Voltage Battery Service Disconnect The high voltage battery service disconnect is located under the access panel, under the left side rear seat. Only a qualified service technician should access the high-voltage battery service disconnect. If your vehicle requires high-voltage battery service, see an authorized dealer.

WARNING

• Never try to remove the high-voltage battery service disconnect. The high-voltage battery service disconnect is used when your vehicle requires ser-vice by a qualified technician at an authorized dealership. Failure to follow this warning can result in electrical shock, toxic emissions, fire, and other hazards that can cause death or serious injury including severe burns, respiratory injuries, and blindness.
• The high-voltage battery and battery case have no parts that you or an unqualified technician can service. Under no circumstances should you or an unqualified technician open, disassemble, penetrate, or tamper with the high voltage battery, battery case, cables, or connectors. Damage to these components can result in electrical shock, toxic emissions, fire, and other hazards which can cause death or serious injury including severe burns, respiratory injuries, and blindness. You should take the vehicle to an authorized dealer-ship for any service or maintenance on these high-voltage components.
• The high voltage system can be hot during and after starting, and when the vehicle is shut off or charging. Be careful of both the high voltage and the high temperature. Failure to do so can result in severe burns.

Disposal of the High Voltage Battery
Your vehicle’s high-voltage battery is designed to last the life of your vehicle. See an authorized dealer for information on the disposal of the battery if it should require replacement.
WARNING: Your vehicle contains a sealed Lithium-ion high-voltage battery. If the battery is disposed of improperly, there is a risk of electrical shock and toxic emissions which can cause severe burns, respiratory injuries, fires, and other hazards resulting in serious injury or death.

General Information
The vehicle is also equipped with a Battery management system that is designed to:

• Ensure safe operation
• Maximize driving range
• Maximize the life expectancy of the high-voltage battery

NOTE: During vehicle start-up and shutdown, a clicking noise may be heard from within the vehicle. When the vehicle is preparing to start, the high voltage battery contactors inside the battery are closed to make the stored electricity inside available for vehicle use. After the vehicle is shut down, the contactors open, to electrically isolate the battery from other vehicle systems. The clicking noise is the sound of these contactors as they open and close during normal operation.

WARNING: In the event of a collision:

• If your vehicle is still drivable, pull off to the side of the road when safe to do so, place the transmission in the PARK position, apply the parking brake, and turn the vehicle off.
• Beware of any exposed high-voltage parts or cables. To avoid electrical shock which can result in serious injury or death, never touch wiring, connectors, and other high-voltage parts, such as the inverter unit and the Lithium-ion battery.
• Leaks or damage to the Lithium-ion battery may result in a fire and toxic emissions which can cause severe burns, respiratory injuries, and other serious injuries or death. If you discover these leaks, contact emergency services immediately. Since the fluid leak may be Lithium Manganate from the Lithium-ion battery, never touch the fluid leak inside or outside of the vehicle. If the fluid contacts your skin or eyes, wash these areas immediately with a large amount of water and obtain immediate medical attention to help avoid serious injury.
• If a fire occurs inside your vehicle, leave the vehicle as soon as possible. Only use a type ABC, BC, or C fire extinguisher that is meant for use on electrical fires. Using a small amount of water, or the incorrect fire extinguisher can result in serious injury or death from electrical shock.
• If you are not able to safely assess the vehicle due to vehicle damage, do not touch the vehicle. Leave the vehicle and contact emergency services. Advise first responders that this is a hybrid-electric vehicle.
  In the event of an accident that requires bodywork, refer to an authorized dealership.

BATTERY CONDITIONING
In extreme temperatures, high or low, the high-voltage battery may need to be conditioned and therefore may require the vehicle to be plugged in. If the ambient temperature is 5°F (-15°C) or below at vehicle shutdown, the instrument cluster will display the message “Plug In Vehicle To Condition Battery”. If the battery temperature is below -22°F (-30°C), or 131°F (55°C) or above, the vehicle will NOT start:

• If the vehicle is plugged in at these battery temperatures, the instrument cluster will display the message “Please Leave Key In RUN — Battery Condition-ing Needed”.
• If the vehicle is not plugged in at these battery temperatures, the “Plug In Vehicle To Condition Battery” will be shown in the instrument cluster display.

NOTE

• When the “Please Leave Key In RUN — Battery Conditioning Needed” message is displayed, keep the ignition in the RUN position for the battery to recover. Place the ignition back in the OFF position when the message disappears, and then start the vehicle. When this message is displayed, do not operate any air conditioning controls.
• Under these high or low temperatures, while the vehicle is plugged in and the ignition is in the OFF position, the vehicle may “wake up” to precondition the high-voltage battery for use.
• It is recommended that the vehicle be plugged in overnight when possible to maximize the electric range of the vehicle.
• It is recommended that the high voltage battery not be exposed to direct sunlight in high-temperature environments while the vehicle is OFF. This may lower the life of the battery.

The messages will only be displayed when the ignition is in the RUN position and the high-voltage battery is not ready to provide propulsion power. The messages will also display if there was a failed attempt to achieve the READY state when the high-voltage battery cell temperatures were either too cold or too hot.

OFF-BOARD POWER PANEL
WARNING:  IMPORTANT SAFETY INSTRUCTIONS about RISK OF FIRE OR ELECTRIC SHOCK: This publication contains important instructions and warnings that should be followed during the use of the Off-Board Power Panel feature. Before using the Off-Board Power Panel, make sure to check the equipment for any leaks or water damage. Failure to follow these warnings and instructions can result in electrical shock and fire which can cause death or serious injury.

• The engine may idle during use to power the outlets. A running engine emits exhaust containing carbon monoxide, which can cause injury or death if inhaled. Never use in closed or confined spaces.
• Never use the Off-Board Power Panel, vehicle charging port, or 3-pin outlet power plug while in use with wet hands. Always handle the Off-Board Power Panel with dry hands. Never use or allow the Off-Board Power Panel to get wet. Do not use it in wet locations, and do not submerge it in water. Only use electrical equipment with a waterproof function/rating, or use it in a waterproof environment. Do not use in environments with rain or high humidity.
• Never insert metal objects into the Off-Board Power Panel connectors, or in the vehicle charging port, as this action can damage the connection terminals.
• Never disassemble the Off-Board Power Panel.
• Do not overload electrical extension cords.
• If there is a risk of lightning, do not use the Off-Board Power Panel system outside the vehicle.
• When the Off-Board Power Panel is in operation, the vehicle’s cooling fan can operate automatically even if the vehicle is turned off.
• Do not put your hands near the cooling fan while it is operating.
• Never use electrical equipment that requires a continuous power supply, such as medical equipment. The power supply may be interrupted depending on the vehicle’s condition.

The Off-Board Power Panel enables the transfer of energy from the vehicle to the external load (utility tools, electric toaster, dryer, or camping equipment), which is connected to a power socket on the Off-Board Power Panel.

NOTE

• When the Off-Board Power Panel is plugged in, and the button is not pushed on the panel, the vehicle will not receive the needed information for providing power to the load. The vehicle will alert an “External issue detected” pop-up and fault indications. When the button on the power panel is pressed, the faults will be cleared and the power transfer will happen.
• Once the Off-Board Power Panel is enabled, and the power transfer does not begin for 60 minutes, the authentication will time out. Turn on the vehicle to re-authenticate the use of the Off-Board Power Panel.
• During the 60 minutes, the authentication is valid, and when power transfer is not in progress, the Off-Board Power Panel may transition to sleep mode. In that case, pushing the Off-Board Power Panel button will turn the feature on and loads can be connected to draw power.
• The Off-Board Power Panel will be reset to OFF every time the Off-Board Power Panel assembly is unplugged.
• When the Off-Board Power Panel assembly is plugged in, the vehicle will not be able to achieve a drive-ready state.
• When the Off-Board Power Panel is activated,
  re-authenticating the key will be required to achieve a drive-ready state.

The Off-Board Power Panel provides maximum flexibility in powering off-board loads using the high voltage system under three modes of operation:

1. Hybrid Mode
   • Hybrid Mode offers a balance of efficiency and duration of power availability.
   • Press the Max Regeneration button and once illuminated Hybrid mode is activated.
   • Defaults to engine-on as the mode is entered (if not already running). Runs for a minimum of five seconds then shuts off if required conditions are met
   • Battery charges till the minimum threshold percentage is reached, then the engine shuts off. Hybrid charging/depletion cycle commences and the engine runs as necessary and turns on/off periodically
   • A low-fuel warning is displayed on the instrument cluster display, and the engine shuts off. The panel draws power from the battery until mini-mum SOC is reached (the engine never restarts)
2. Electric Mode
   • Available in the SOC is above the minimum threshold
   • High voltage battery provides power until depleted, then the panel deactivates
   • The engine never turns on
3. Generator Mode
   • Engine runs to charge the battery and power the system (run post-start required)
   • Engine runs while charging the battery until a low fuel level is reached or the battery SOC is maxed
   • Low-fuel warning is displayed on the instrument cluster display or the battery SOC is reached. The engine shuts off and the panel draws power from the battery until the minimum SOC is reached if the engine never restarts

NOTE: If the off-board power panel is in Hybrid Mode and the Max Regeneration button is pressed for a second time, the off-board power panel will default to Generator Mode if the engine is ON and running. The off-board power panel will default to Electric Mode if the battery SOC is above the minimum threshold plus the engine is off. If the engine is off and the SOC is below the minimum threshold the system will fault and will turn off.
