GM Service Manual Online
For 1990-2009 cars only
An arrow on the instrument panel cluster flashes in the direction of the turn or lane change.

To signal a turn, move the lever all the way up or down.

To signal a lane change, raise or lower the lever until the arrow starts to flash. The turn signal automatically flashes three times and if the tow-haul mode is active it flashes six times. Holding the turn signal lever for more than one second causes the turn signals to flash continually until the lever is released.

The lever returns to its starting position when released.

If after signaling a turn or lane change the arrow flashes rapidly or does not come on, a signal bulb may be burned out.

Have the bulbs replaced. If the bulb is not burned out, check the fuse. See Fuses and Circuit Breakers .

Turn Signal On Chime

If the turn signal is left on for more than 3/4 of a mile (1.2 km), a chime sounds at each flash of the turn signal and the message TURN SIGNAL ON also appears in the Driver Information Center (DIC). See DIC Warnings and Messages . To turn off the chime and message, move the turn signal lever to the off position.
