Emergency Stop Signal
System
▼ Emergency Stop Signal System
If you apply the brakes suddenly while
driving at a speed of about 55 km/h
(34 mph) or faster, the emergency stop
signal system automatically and rapidly
flashes all the direction indicator lights
to caution drivers behind your vehicle
of the sudden braking situation.
NOTE
Flashing

When you bring your vehicle to a
complete stop while all the direction
indicator lights are flashing rapidly,
the rapid flashing of all the direction
indicator lights changes back to the
normal flashing pattern. The
direction indicator lights turn off
when you release your foot from the
brake pedal.
Operation

When the ABS operates, the

emergency stop signal system is
more likely to operate. Therefore, if
the brake pedal is depressed on a
slippery road, all of the direction
indicator lights may flash.
The emergency stop signal system

does not operate when the hazard
warning light switch is pressed.
