Chevrolet 1993 S-10 Pickup Owner's Manual page 89

To signal a lane change, just raise or lower the lever until the green arrow
starts to flash. Hold it there until you complete your lane change. The lever
will return by itself when you release it.
As you signal a turn or a lane chi'
- -
if the arrows don't flash but just stay
on, a signal bulb may be burned
OUT
and
other drivers won't see your turn
signal.
(If your vehicle has the digital instrument cluster, the turn signal arrows will
flash at a faster rate if a signal bulb is burned out.)
If a bulb is burned out, replace it to help avoid an accident. If the green
arrows don't go on at all when you signal a turn, check the fuse (see
"Fuses" in the Index) and for burned-out bulbs.
If you have a trailer towing option with added wiring for the trailer lights, a
different turn signal flasher is used. With this flasher installed, the signal
indicator will flash even if a turn signal bulb is burned out. Check the front
and rear turn signal lights regularly to make sure they are working.
Operation of Lights
Although your vehicle's lighting system (headlights, parking lights, fog lamps,
side marker lights and tail lights) meet all applicable Federal lighting
requirements, certain states and providences may apply their own lighting
regulations that may require special attention before you operate these lights.
For example, some jurisdictions may require that you operate your lower
beam lights with fog lamps at all times, or that headlights be turned on
whenever you must use your windshield wipers. In addition, most jurisdictions
prohibit driving solely with parking lights, especially at dawn or dusk. It
is
recommended that you check with your own state or provincial highway
authority for applicable lighting regulations.
