Rescue Sheet
Mullen Automotive, Inc. (Mullen) electric vehicles use an electric motor for power and the electricity required to power this electric motor is stored in a high voltage battery pack. Lack of engine noise does not mean the vehicle is off. Silent movement or instant restart capability exists until the vehicle is fully shut down using the Manual Service Disconnect (MSD). When approaching an electric vehicle of this nature in a fire, rescue, or recovery situation, follow this industry standard rule: Always assume the high voltage system is live!

See Component Index section located on Page 7 for additional information. THIS VEHICLE DOES NOT CONTAIN AIRBAGS.

THIS VEHICLE IS NOT EQUIPPED WITH "PARK" ON THE GEAR SELECTOR. YOU MUST ALWAYS ENGAGE THE PARKING BRAKE LOCATED TO THE RIGHT OF THE DRIVER'S SEAT.

Disabling High and Low Voltage Systems
Disable both voltage systems by following the instructions below:
STEP ONE:
Turn OFF the vehicle and remove the key from the ignition. 1. Confirm that the vehicle is at a standstill. 2. Ensure parking brake is securely engaged on level ground ("Park" telltale will illuminate to indicate parking brake is engaged in the driver's cluster). 3. Vehicle must be in the Neutral (N) gear position ("N" telltale will illuminate to indicate Neutral gear position is engaged in the driver's cluster). 4. Turn the key in the ignition to the "OFF" position and remove the key from the ignition. 5. Position wheel and tire chocks to prevent rolling or shifting of the vehicle.

Jacking Points
See Component Index section located on Page 2 for additional information.
STEP TWO:
Tilt Cab Forward to access voltage systems. (See below images numerically identifying the process). Locate the cab release handles on the lower exterior of the cab, to the right of the driver's side door.
1. Place your left hand through the stationary black cab handle. 2. Grasp the gold latch release bar towards you. 3. Simultaneously while holding the gold latch, use your right hand and push the cab release lever
upwards. 4. Then use the right hand, once the cab lever is released, to pull the safety release straight towards you. 5. Make sure that when the cab is lifted, the safety latch on the torsion bar is locked into place. 6. Then pull the lock out key from clasp. 7. Insert key into keyhole to secure cab in place.

STEP THREE:
Turn 12-Volt Master Power Switch OFF. 1. Locate the red 12-Volt Master Power Supply Handle located on the driver's side behind the cab straight up and down handle located driver's side behind the cab. 2. Turn the 12-Volt Master Power Supply Handle counterclockwise from the vertical, i.e., straight up and down position to switch from the "ON" position to the "OFF" position. 3. The Master Power Switch must be turned to the horizontal "OFF" position before disconnecting both the negative and positive battery terminals. 4. Locate the 12-Volt battery and identify the positive (red) and negative (black) terminals. The negative terminal is marked with a minus symbol and the positive is marked with a plus symbol. 5. Use an insulated wrench to loosen the nut holding the cable onto the negative terminal. 6. Remove the cable by lifting it free. Be careful not to let it touch the positive terminal or any metal part of the vehicle. 7. Repeat the same process state above to disconnect the positive terminal.

Stored Energy / Liquids / Gases / Solid

In Case of Fire
If the vehicle is on fire, use a Class ABC powder-type extinguisher to contain and smother the flames. · While not ideal, water can be used in copious amounts to extinguish the flames. The cooling and smothering effects of water flushing the affected article is still beneficial for minimizing the severity of the event. · Note that water can cause some degree of arcing/shorting across exposed battery cells and terminals; it can also react with the electrolyte from the battery cells to generate combustible gases and other byproducts such as hydrofluoric acid.

In Case of Submersion
If the vehicle is submerged in water, varying degrees of arcing/shorting within the battery will take place. · Do not remove the vehicle until you are sure the high voltage battery is completely discharged. · A submerged high voltage battery may produce a fizzing or bubbling reaction to the water. · If fizzing or bubbling is observed, the high voltage battery is not fully discharged.

Moving Damaged Vehicles
If the vehicle becomes disabled and requires towing, make sure to do the following: · Make sure the gear shift lever is in NEUTRAL (N) position and the parking brake is disengaged. · Disengage high voltage components by turning high voltage master switch to OFF position.
The rear tow hook is located on the back edge of the frame on the passenger side.

WHEN TOWING THE VEHICLE, USE A FLATBED TRAILER OR TOW FROM THE FROM THE FRONT WHEELS. TOWING FROM THE REAR WHEELS CAN DAMAGE THE VEHICLE.

Damaged Vehicle Storage
· Ensure the damaged vehicle(s) remains in an open area instead of inside a garage or other enclosed building.
· Do not store a severely damaged vehicle with a lithium iron phosphate battery within 50 feet of any occupied structure or vehicle.
· Make sure the passenger and cargo compartments remain ventilated. · Regularly inspect damaged vehicles for fluid leaks, sparks, smoke, flames, gurgling or bubbling sounds
from the high voltage battery and call 911 if any of these are detected.

High Volt Battery Handling & Storage
Handling: · Do not open or disassemble the batteries. · Do not mix batteries of varying size or chemicals. · Do not connect the positive and negative battery terminals with conductive material.
Storage: · Batteries should be stored in a well-ventilated area with sufficient clearance between batteries and walls. · Store the batteries in a cool area (below 30) away from moisture. · Keep the batteries away from sources of heat and open flames.
