Emergency stop signal activates when the system detects hard braking about 50 km/h (31 mph) or above to alert drivers behind you about sudden braking by rapidly flashing both turn signal lights. This may help to alert drivers behind you to take appropriate means to avoid a possible collision with your vehicle.
The emergency stop signal stops operating when:
You release the brakes.
The ABS is deactivated.
Your vehicle's decelerating speed becomes moderate.
You press the hazard switch.
When the system activates:
Hard braking
Brakelight comes on
Both turn signals flash
Both turn signal indicators blink
The emergency stop signal is not a system that can prevent a possible rear-end collision caused by your hard braking. It is always recommended to avoid hard braking unless it is absolutely necessary.
The emergency stop signal does not activate with the hazard switch pressed in.
If the ABS stops working for a certain period during braking, the emergency stop signal may not activate at all.
