GMC 1995 Safari Owner's Manual page 83

A green arrow on the
instrument panel will
flash in the direction
of the turn or lane
change.
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 change, 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 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.
Headlamp High-Low Beam
To change the
headlamps from low
beam to high or high
to low, pull the turn
signal lever all the
way toward you. Then
release it.
