There is a risk of a thermal reaction in the high-voltage battery if coolant escapes
from the battery cooling system.
Monitor the temperature of the high-voltage battery.
6. In case of fire
Lithium-ion batteries can self-ignite spontaneously or after a delay in the event of
damage or incorrect use, and can re-ignite after a fire has been suppressed.
Wear suitable safety equipment.
7. In case of submersion
After recovering the vehicle from the water, deactivate the high-voltage system (see Section 3) and
allow the water to drain off. Wear suitable safety equipment.
8. Towing / transportation / storage
Lithium-ion batteries can self-ignite, or re-ignite after a fire has been extinguished.
If the vehicle has been involved in an accident or if the HV battery is damaged or suspicious:
Deactivate the high-voltage system (see Section 3). Park the vehicle at a safe distance, at least 5 m,
from buildings and other vehicles (quarantine area).
Do not tow a vehicle that has been involved in an
accident on its drive axles.
