High-voltage battery overheating warning light

What it means

The traction-battery temperature is too high. Steady and flashing states have different responses.

What to do

For a steady warning, stop the vehicle to cool down. If it flashes, immediately stop safely and leave the vehicle as soon as possible, as this edition instructs. Do not substitute the motor-coolant response.
