Toyota Yaris: If Trouble Arises / Parking in an Emergency
The hazard warning lights should
always be used when you stop on
or near a roadway in an emergency.

The hazard warning lights warn
other drivers that your vehicle is a
traffic hazard and that they must
take extreme caution when near
it.

Depress the hazard warning flasher and all the turn signals will flash.
The hazard warning indicator lights in the combination meter flash
simultaneously.
- The turn signals do not work when the hazard warning lights are on.
- Check local regulations about the use of hazard warning lights while the
vehicle is being towed to verify that it is not in violation of the law.
