GMC SIERRA 1993 Owners Manual

Turn Signa/ and Lane Change Indicator
(I
The turn signal has two upward (for Right) and two downward \
(for Left)
positions. These positions allow you to signal a turn
or a lane change.
To signal a turn, move the lever all the way up or down. When the turn is
finished, the lever will return automatically.
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 flash twice as fast as
normal, 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.

hts, fog lamps,

lighting
requirements, certain states and provinces may apply their own lighting
regulations that may require special attention before you operat\
e these lights.

accelerator pedal.

to the speed you want, and then release the switch.

To Reduce Speed While Using Cruise Control
1
K2260
1. Push in the button at the end of the lever until you reach the lower
speed you want, then release it.
2. To slow down in very small amounts, push the button for less than a
half second. Each time you do this, you’ll go 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When you take your foot
off the pedal, your vehicle will slow down to the Cruise Control speed you set
earlier.
Using Cruise Control on Hills
How well your Cruise Control will work on hills depends upon \
your speed,
load, and the steepness of the hills. When going up steep hills, you may
have to step on the accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear to keep your speed
down.
Of course, applying the brake takes you out of Cruise Control. Many
drivers find this to be too much trouble and don’t use Cruise Control on
steep hills.
When you turn
off the Cruise Control or the ignition, your Cruise Control set
speed memory
is erased.
