Ignition Positions
With your key in the ignition switch, you can turn it to
five different positions.
A (ACCESSORY): This position allows you to
use things like the radio, power windows and the
windshield wipers when the engine is off. To get into
ACCESSORY, push in the key and turn it toward you.
Your steering wheel will remain locked, just as it was
before you inserted the key.
B (LOCK): This position locks your ignition, steering
wheel and transmission. It's a theft
-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.
C (OFF): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK. Use OFF if you must have your
vehicle in motion while the engine is off (for example, if
your vehicle is being pushed).
D (RUN): This is the position for driving.
E (START): This position starts your engine.

When the yellow SYSTEM PARK and the red
TRAILER AIR SUPPLY knobs are both pushed
in, your rig will be free to move. It could strike
someone or something. When both of these knobs
are pushed in, hold the regular brake pedal down
to keep your rig from moving.
If your vehicle has air
brakes, you will have this
parking brake. It is located
above the radio in the
instrument panel.
Pulling it out applies the parking brake. The park brake
light will come on when the air parking brake is applied.

Interior Lamps
Instrument Panel Brightness Control
This feature controls the brightness of the instrument
panel lights.
The thumbwheel for this feature is located to the right of
the exterior lamp control.
Turn the thumbwheel up to brighten the lights. When the
thumbwheel is moved to the first position, the radio
display and transmission selection display will go to full
intensity. The instrument panel cluster will also be dimly
lit. Moving the thumbwheel up to the next position will
activate the interior dome lamps.
Dome Lamps
The dome lamps will come on when you open a door.
You can also turn the dome lamps on by moving the
thumbwheel, located to the right of the exterior lamp
control, all the way up to the second position. In this
position, the dome lamps will remain on whether a door
is open or closed.
You can use the dome override button to set the dome
lamps to automatically come on when a door is open, or
to remain off.
The dome override button is located below the exterior
lamp control.
If the dome override button is pushed in, the dome
lamps will not come on. Use this feature when you want
to leave your door(s) open for an extended period of
time and do not want to run the battery down.
If the dome override button is in the out position, the
interior lamps will work as usual.

Ashtrays and Cigarette Lighter
Your vehicle has an ashtray and a cigarette lighter
located in the center floor console. To open the
removeable ashtray, flip open the top.
NOTICE:
If you store paper or other things that burn in your
ashtrays, they could be set on fire by cigarettes or
other smoking materials. That could cause a fire
and possibly damage your vehicle. Do not store
papers and other things that burn in your ashtrays.
To use the cigarette lighter, push it in all the way and let
it go. When it's ready, it will pop back out by itself.
NOTICE:
Holding a cigarette lighter in with your hand
while it's heating can make it overload, damaging
the lighter and the heating element. Just push the
lighter all the way in and let it go. When it's
done, it will pop back out by itself.
Sun Visors
To block out glare, you can swing down the visors. You
can also swing them out to block glare from the side.
Accessory Power Outlets
With accessory power outlets, you can plug in
auxiliary electrical equipment such as a cellular
telephone or CB radio.
The accessory power outlets are located on the
passenger's side of the instrument panel.
To use an outlet, pull the cover down. When not using it,
always cover the outlet with the protective cap.
These circuits are protected by a fuse and have
maximum current levels.
NOTICE:
When using the accessory power outlets,
maximum load of any electrical equipment
should not exceed 14 amps. Be sure to turn off
any electrical equipment when not in use.
Leaving electrical equipment on for extended
periods can drain the battery.

2-78 Charging System Indicator Light
The charging system
indicator light may be
located in the instrument
panel cluster, or with the
auxiliary warning lights
in the center of the
instrument panel.
It should come on briefly when you turn on the ignition,
before the engine is running, as a check to show that it
is working.
If it stays on, or comes on while you are driving, have it
checked right away. You could have a loose generator
drive belt or some other problem.
Driving while this light is on will drain your battery. If
you must drive a short distance with the light on, turn
off your radio and other accessories.
Sustained driving with a generator failure could result in
a lack of back
-up braking if the engine quits or the
power steering pump should fail.
Voltmeter
When your engine is
running, the voltmeter
gage, at the right side of
the instrument panel cluster,
shows the charging
system voltage.
Readings in either warning zone indicate a possible
problem in the electrical system.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in the
vehicle and the engine is left at an idle for an extended
period. This condition is normal since the charging
system may not be able to provide full power at engine
idle. As engine speeds are increased, this condition
should correct itself because higher engine speeds allow
the charging system to create maximum power.
You can only drive a short time on the battery. Be sure
to shut off the radio, the fan or any unnecessary
accessories and have the system serviced.
