Buick Enclave: Hazard Warning Flashers. Turn and Lane-Change Signals. Turn Signal On Chime
Hazard Warning Flashers

Hazard Warning Flasher:
Press this button, located on the instrument panel below the audio system, to make the front and rear turn signal lamps flash on and off at the same time.
When the Buick Enclave hazard warning flashers are operating, they warn other drivers that the vehicle may be stopped, disabled, moving slowly, or experiencing a roadside situation that requires extra caution. Press the button again to turn the flashers off.
The turn signals will not operate normally while the hazard warning flashers are on.
Turn and Lane-Change Signals

An arrow in the instrument panel cluster flashes in the direction of the turn or lane change.
Move the lever all the way up or down to signal a full turn.
To signal a lane change, raise or lower the lever only until the arrow begins to flash. Hold the lever in that position until the lane change is complete. If the lever is pressed briefly and released, the turn signal will flash three times.
The lever returns to its starting position when it is released.
If the arrow flashes rapidly after signaling a turn or lane change, or if it does not come on at all, a turn signal bulb may be burned out.
Have the bulbs replaced if necessary. If the bulb is not burned out, check the related fuse.
See Fuses and Circuit Breakers.
Turn Signal On Chime
If either turn signal is left on and the vehicle has been driven more than 1.2 km (0.75 mi), a chime will sound to remind the driver to cancel the signal.
