1997 GMC SIERRA bulb

nrn 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
tum, move the lever all the way up or down.
When the
tum is finished, the lever will return automatically.
CII
An 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 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 High/Low Beam Changer
To change the headlamps from low to high beam or high
to low beam, pull the multifunction lever all the way
towards you. Then release it.
When the high beams are
on, this light on the
instrument panel also
will be on.

Turn Signals When Towing a Trailer
The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs
on the trailer
are burned out. Thus, you may think drivers behind you
are seeing your signal when they are not. It’s important
to check occasionally to be sure the trailer bulbs are
still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down,
you might have to use your brakes so much that
they would get hot and no longer work well.
On
a long uphill grade, shift down and reduce your
speed
to around 45 mph (70 km/h) to reduce the
possibility of engine and transmission overheating. If you have an automatic transmission, you can tow
in
AUTOMATIC OVERDRIVE (a). You
may want to
shift the transmission to THIRD
(3) or, if necessary, a
lower gear selection if the transmission shifts too often
(e.g., under heavy loads and/or hilly conditions).
If you have a manual transmission and you are towing a
trailer, it’s better not to use
FIFTH (5) gear. Just drive in
FOURTH
(4) gear (or, as you need to, a lower gear).
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than at normal altitudes. If
you turn
your engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating.
To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in
PARK (P) (or the
manual transmission out of gear and the parking brake
applied) for a few minutes before turning the engine
off.
If you do get the overheat warning, see “Engine
Overheating”
in the Index.

Battery
Every new vehicle has a Delco Freedom@ battery. You
never have to add water to one
of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get one that
has the replacement number shown
on the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more,
take
off the black, negative (-) cable from the battery.
This will help keep your battery from running down.

Bulb Replacement
Before you replace any bulbs, be sure that all the lamps
are off and the engine isn’t running. See “Replacement

that can explode. You can be badly hurt if you
aren’t careful. See
“Jump Starting” in the Index
for tips on working around
a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
