1998 GMC SIERRA headlamp

You can shift from 2-WHEEL HIGH (2H) to 4-WHEEL
HIGH (4H) or from 4-WHEEL HIGH (4H) to
2-WHEEL HIGH (2H) while
the vehicle is moving.
Your front axle will engage faster
if you take your foot
off the accelerator for a few seconds after you shift. In
extremely cold weather, it may be necessary to stop or
slow the vehicle
to shift into 4-WHEEL HIGH (4H).
To
shift into or out of 4-WHEEL LOW (4L) or
NEUTRAL
(N):
1. Slow the vehicle to a roll, about 1 to 3 mph
(2
to 5 km/h) and shift an automatic transmission
into NEUTRAL
(N), or with a manual transmission,
press the clutch pedal.
2. Shift
the transfer case shift lever in one
continuous motion.
Don’t pause
in NEUTRAL (N) as you shift the
transfer case into 4-WHEEL LOW (4L), or your
gears
could clash.
Remember that driving
in 4-WHEEL HIGH (4H) or
4-WHEEL LOW (4L) may reduce
fuel economy. Also,
driving
in four-wheel drive on dry pavement could
cause your tires to wear faster and make your transfer
case harder
to shift and run noisier. When your headlamps
or parking lamps are on, rotate the
thumb wheel next
to the headlamp switch up to brighten
or down to dim your transfer case indicator light.
Electronic Transfer Case (If Equipped)
If your four-wheel-drive vehicle has the electronic
transfer case,
the transfer case switches are below and to
the left of the climate control system.

Turn SignaVIWultifunction Lever Turn Signal and Lane Change Signals
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.
An arrow on the instrument
panel will flash
in the
direction
of the turn or
lane change.
The lever on the left side
of the steering column
includes your:
0 Turn Signal and Lane Change Indicator
0 Headlamp High/Low Beam Changer
0 Windshield Wipers
0 Windshield Washer
0 Cruise Control (If Equipped)
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there
until you
complete your lane change. The lever will return by
itself when you release it.
If you move the lever all the way up or down, and the
arrow flashes at twice the normal rate,
a signal bulb may be
burned out and other drivers may not see your
turn signal.

If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you
signal
a turn, check for burned-out bulbs and a blown
fuse (see “Fuses and Circuit Breakers”
in the Index).
Headlamp HighLow-Beam Changer
To change the headlamps from low to high beam or high
to low beam, pull the multifunction lever all the way
toward
you. Then release it.
When the high beams are

Windshield Wipers
You control the windshield
wipers
by turning the knob
with the wiper
symbol on it.
For a single wiping cycle, turn the knob to MIST. Hold
it there until the wipers start, then let
go. The wipers will
stop after one cycle.
If you want more cycles, hold the
knob on MIST longer.
You can set
the wiper speed for a long or short delay
between wipes. This can be very useful
in light rain or
snow. Turn the knob to choose the delay time. The
closer to

Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful
in many different driving
conditions, but they can be especially helpful
in the
short periods after dawn and before sunset.
The DRL system
will make your headlamps come on at
a reduced brightness when:
0 the ignition is on,
0 the headlamp switch is off and
the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t
be on.
Your instrument panel won’t be lit
up either.
When it begins to get dark, your DRL indicator light is a
reminder to turn your headlamp switch on. The other lamps
that come
on with your headlanips will also come on.
When you
turn off the headlamp switch, the regular
lamps will
go off, and your headlamps will change to
the reduced brightness of DRL.

off, the
fog lamps will come on again.
