Seats and Seat Controls
This section tells you about the seats in your vehicle and
how to adjust them.
CAUTION:
You can lose control of the vehicle if you try to
adjust the seat while the vehicle is moving. The
sudden movement could startle and confuse you,
or make you push a pedal when you don't want
to. Adjust the driver's seat only when the vehicle
is not moving.
Bucket and Bench Seats
If your vehicle has a bucket or bench seat, you can
adjust it with this lever at the front of the seat.
Slide the lever toward the outer seat support to unlock it.
Slide the seat to where you want it. Then, release the
lever and try to move the seat with your body to make
sure the seat is locked into place.

2-33 Turn Signal and Lane Change Indicator
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
cluster 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.
As you signal a turn or a lane change, if the arrows don't flash
but just stay on, check the turn signal flasher and circuit
breaker. See ªFuses and Circuit Breakersº in the Index.
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 the circuit breaker and for
burned
-out bulbs. (See ªFuses and Circuit Breakersº in
the Index.)
Signal-Stat Turn Signal and Hazard
Warning Flasher (If Equipped)
If you have this signal system, it is mounted beside or
behind the multifunction lever on the left side of the
steering column.
To signal a turn, move the lever all the way up or down.
When the turn is completed, move the lever back to the
center position.

NOTICE:
Don't put papers and other things that burn into
your ashtray. If you do, cigarettes or other
smoking materials could set them on fire,
causing damage.
Sun Visors
To block out glare, you can move the sun visors. You
can also swing them from side to side.
Auxiliary Power Jacks (If Equipped)
If your vehicle has these
power jacks, you'll find
them in the ashtray.These jacks provide 12
-volt power so you can operate
things such as a citizen's band (CB) radio or a cellular
phone. You'll see positive (red) and negative (black)
outlets. They have a 20
-amp fuse that is common with
the cigarette lighter. Don't use the cigarette lighter when
you're using a power jack because it may overload the
circuit and blow the fuse.
NOTICE:
Whether or not your vehicle has the power
outlets, don't plug in FM communications gear at
the ashtray area. FM equipment creates high
heat, and over time the area could get so hot that
wires could be damaged or a fire could even
break out.

2-70 Filterminder Gage (Diesel Engine)
This optional gage is in the
lower center of the
instrument panel. It
monitors the engine
air filter.
As the filter gets dirty, the yellow indicator will begin to
rise. When it reaches 25 inches of vacuum on the scale,
the filter should be replaced.
After replacing the filter, reset the gage by pressing in
the yellow reset pin at the bottom of the gage.
If you have a diesel engine, also see your Caterpillar


Operation & Maintenance Manual.
Hourmeter Gage (If Equipped)
If your vehicle has this
gage, it will be to the lower
left of the steering column,
mounted on a bracket either
above or below the fuse
block. It shows the total
engine operating time.

Service
Your dealer knows your vehicle best and wants you to
be happy with it. We hope you'll go to your dealer for
all your service needs. You'll get genuine GM parts and
GM
-trained and supported service people.
We hope you'll want to keep your GM vehicle all GM.
Genuine GM parts have one of these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you'll
want to use the proper service manual. It tells you much
more about how to service your vehicle than this manual
can. To order the proper service manual, see ªService
and Owner Publicationsº in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See ªMaintenance Recordº in the Index.
CAUTION:
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.

Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.

Be sure to use the proper nuts, bolts and
other fasteners. ªEnglishº and ªmetricº
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.

Electrical System
Add-On Electrical Equipment
NOTICE:
Don't add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn't be covered by your
warranty. Some add
-on electrical equipment can
keep other components from working as
they should.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the light switch. An electrical overload will cause the
lights to go on and off, or in some cases to remain off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker inside the motor and a circuit breaker in the fuse
block. If the motor overheats, the wipers will stop until
the motor cools. If the overload is caused by an
electrical problem, be sure to get it fixed.
Fusible Links
A fusible link is a short piece of wire several gage sizes
smaller than the circuit it protects. It will melt in an
overload situation, opening the circuit.
Your starter relay and other circuits have these fusible
links. The size is printed on the insulation. If the insulation
is burned beyond recognition, consult your GM dealer for
the proper size. Replace a fusible link with one of the
same size and insulation type. Fusible link insulation is a
special purpose high
-temperature material.
The hydraulic brake booster motor feed circuit and
starter relay circuit are protected by a fusible link.
Vehicles with a diesel engine have a fusible link for the
intake heater feed circuit. Vehicles equipped with an
electronically controlled diesel engine also have a
fusible link for the engine control unit.
