Hazard Warning Button, Rear Window Defogger Hazard Warning Button Rear Window Defogger Make sure the rear window is clear and you have good visibility before starting to drive. The defogger and antenna wires on the inside of the rear window can be accidentally damaged. When cleaning the glass, always wipe side to side. Push the button between the center vents to turn on the hazard warning lights (four-way flashers). This causes all four outside turn signals and both indicators in the instrument panel to flash. Use the hazard warning lights if you need to park in a dangerous area near heavy traffic, or if your vehicle is disabled. The rear window defogger will clear fog, frost, and thin ice from the window. Push the defogger button to turn it on and off. The indicator in the button comes on to show the defogger is on. If you do not turn it off, the defogger will shut itself off after about 15 minutes. It also shuts off when you turn off the ignition switch. You have to turn the defogger on again when you restart the vehicle. 64
