HAZARD WARNING FLASHER
The Hazard Warning Flasher switch is located on the
lower switch bank below the climate controls.
To operate the Hazard Warning flasher, press the switch
and all front and rear directional signals will flash
intermittently. Press the switch a second time to turn off
the flashers.
This is an emergency warning system and should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and is creating a safety hazard for
other motorists.
If it is necessary to leave the vehicle to go for service, the
Hazard Warning flasher will continue to operate with the
ignition key removed and the vehicle locked.
NOTE: With extended use, the Hazard Warning flasher
may wear down your battery.
