7. In case of submersion
1. Submerged Vehicle
CAUTION:
If the drive battery and high voltage system are immersed in water, they will be treated as submerged.
If the vehicle is submerged or partially submerged, remove occupants from the vehicle and water.
Then shut down the 12V auxiliary battery and high voltage system.
If the vehicle is submerged, water may enter the drive battery.
If a small amount of water gets into the drive battery, there is a risk of abnormal heating or fire due to an
internal short circuit.
WARNING:
• If water enters the driving battery, hydrogen gas may be generated.
• When seawater enters, a large amount of hydrogen gas is generated by rapid electrolysis due to salinity, which may
cause a fire.
• After the vehicle is pulled out of the water, open the windows and doors as there may be hydrogen gas in the vehicle.
Work procedures
If the vehicle is submerged or partially submerged, take the following work procedures:
1) Rescue the occupants and pull the vehicle out of the water.
2) Inspect the vehicle for damage. In the following cases, wear insulated Personal Protective Equipment (PPE) and
carry out the rescue operation while taking care not to touch the drive battery and orange-colour high voltage
wiring cables.
When the vehicle is severely damaged.
When the drive battery is deformed or damaged, and internal parts are exposed.
When the damage condition of the drive battery cannot be determined.
CAUTION:
If the drive battery is damaged, consult the nearest Mitsubishi Motors Dealer how to handle the drive battery.
