Use the following method to activate the four-way flashers.
  1. With the ignition key ON and security system disarmed (models with security only), press the left and right turn signal switches at the same time.
  2. Turn the ignition key OFF and arm the security system if present and desired. The four-way flashers will continue for two hours.
  3. To cancel four-way flashing, disarm the security system if necessary, turn the ignition key ON and press the left and right turn signal switches at the same time.
This system allows a stranded vehicle to be left in the four-way flashing mode and secured until help is found.
