WARNING
If a High Voltage battery fluid leaks, be
careful not to touch the fluid. It can harm
your eyes and skin. If it comes in contact
with your eyes and skin; flush the affected
area with clean water immediately for a
few minutes, and seek immediate medical
attention.
Do not use a warning flare near a fuel cell
vehicle. If hydrogen gas is leaking, it may
ignite the gas, and result in a vehicle fire.
