If your vehicle has this
power door lock switch,
press the bottom of the
switch on either front door
to lock all the doors at once.
Press the top of the switch to unlock all the doors
at once.
The power door locks will operate at any time without
the ignition being on.
The power door locks will also automatically lock when
the vehicle reaches 15 mph (24 km/h). To unlock the
doors, refer to the instructions listed previously. The
automatic locking feature can be disabled, if you prefer.
See ªProgrammable Automatic Door Locksº in the
following text.
Operating the power locks may interact with the
theft
-deterrent system (if equipped). See ªContent
Theft
-Deterrentº in the Index.
Programmable Automatic Door Locks
Your vehicle is equipped with an auto lock/unlock feature
which enables you to program your power door locks.
Your vehicle left the factory programmed to have the
automatic lock feature lock all the doors when the
vehicle speed is greater than 15 mph (24 km/h) for two
seconds, and then unlock all the doors once the key is
removed from the ignition. The following instructions
detail how to program your door locks.
To enter the program mode you need to do the following:
1. Beginning with the ignition in OFF, pull back on the
turn signal/multifunction lever all the way toward
you and hold it while you perform the next step.
2. Turn your key to ON and OFF twice. Then, with the
key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock.
3. You are now ready to program the automatic door
locks. Select one of the following four programming
options and follow the instructions. You will have
ten seconds to begin programming. If you exceed the
ten second limit, the locks will automatically lock and
unlock to indicate you have left the program mode.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes your:

Turn Signal and Lane Change Indicator

Headlamp High/Low Beam Changer

Flash
-to-Pass

Windshield Wipers

Windshield Washer

Cruise Control (If Equipped)
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.
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 or a blown fuse (see ªFuses
and Circuit Breakersº in the Index).

2-53
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a
mile (1.2 km), a chime will sound at each flash of the
turn signal. To turn off the chime, move the turn signal
lever to the off position.
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
toward you. Then release it.
When the high beams are
on, this light on the
instrument panel also
will be on.
Flash-To-Pass Feature
This feature allows you to use your high-beam
headlamps to signal a driver in front of you that you
want to pass. It works even if your headlamps are off.
To use it, pull the turn signal lever toward you, but not
so far that you hear it click.If your headlamps are off or on low
-beam, your
high
-beam headlamps will turn on. They'll stay on as long
as you hold the lever toward you and the high
-beam
indicator on the instrument panel will come on. Release
the lever to turn the high
-beam headlamps off.
Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on it.

Warning Lights, Gages
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
there's a problem with your vehicle.When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Your vehicle may also have a driver information system
that works along with the warning lights and gages.
See ªMessage Centerº in the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about six seconds to remind people to
fasten their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for about 20 seconds, then
it will flash for
about 55 seconds.
If the driver's belt is already buckled, neither the chime
nor the light will come on.

2. Turn the radio off.
3. Press the 1 and 4 buttons together. Hold them
down until SEC shows on the display.
4. Press MN and 000 will appear on the display.

6. Press HR to make the first one or two digits agree
with your code.
7. Press AM
-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show
---, indicating that the radio
is no longer secured.
If the code entered is incorrect, SEC will appear on the
display. The radio will remain secured until the correct
code is entered.When battery power is removed and later applied to a
secured radio, the radio won't turn on and LOC will
appear on the display.
To unlock a secured radio, see ªUnlocking the
Theft
-Deterrent Feature After a Power Lossº earlier
in this section.
Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.
