It is possible for the PASS-Key III decoder to learn the
transponder value of a new or replacement key. Up to
ten additional keys may be programmed for the vehicle.
This procedure is for learning additional keys only. If all
the currently programmed keys are lost or do not
operate, you must see your dealer or a locksmith who
can service PASS
-Key III to have keys made and
programmed to the system.
See your dealer or a locksmith who can service
PASS
-Key III to get a new blank key that is cut exactly
as a current black
-colored driver's key that operates the
system. Do not use a gray
-colored valet key for
this procedure.
To program the new key:

Insert the current driver's key (black in color) in the
ignition and start the engine. If the engine will not
start see your dealer for service.

After the engine has started, turn the key to OFF, and
remove the key.
Insert the key to be programmed and turn it to ON
within ten seconds of removing the previous key.

The SECURITY light will turn off once the key has
been programmed. It may not be apparent that the
SECURITY light went on due to how quickly the
key is programmed.

Repeat the Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the SECURITY light comes
on and stays on, you will be able to start your engine if
you turn it off. Your PASS-Key III system, however, is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by the PASS
-Key
III system at this time.
If you lose or damage a PASS
-Key III key, see your
dealer or a locksmith who can service PASS
-Key III to
have a new key made.

PUSHBUTTONS: The six numbered pushbuttons let
you return to your favorite Program Types (PTYs).
These buttons have factory PTY presets. See ªRadio
Data Systems (RDS) Program Type (PTY) Selectionsº
in the Index. You can set up to 12 PTYs (six FM1 and
six FM2). Just:
1. Turn PTY on.
2. Press BAND to select FM1 or FM2.
3. Tune in an RDS station with the PTY you desire.
4. Press and hold one of the six numbered buttons for
more than two seconds until you hear a beep.
Whenever you press that numbered button for less
than two seconds, the PTY you set will return.
5. Repeat the steps for each pushbutton.
When battery power is removed and later applied, you
will not have to reset your RDS presets because the
radio remembers them.
HR or MN: Press the RDS SELECT button, followed
by one of these buttons to display the time for the
current station. STATION TIME IS will be displayed.
If a time has not been sent to the radio, NO STATION
TIME will be displayed. If you have recently tuned to
the station, you may need to wait a minute before the
time is available to the radio. To set the clock to thecurrent displayed station time, press and hold HR
or MN until TIME UPDATED is displayed. There is a
two second delay before the time is updated. RDS mode
does not have to be on to use this function, but you must
be tuned to an FM RDS station.
ALERT: This type of announcement warns of national
or local emergencies. You will not be able to turn off
alert announcements. Alert announcements will come on
even if RDS mode is turned off. ALERT appears on the

VOLUME will appear on the display while the volume
is being adjusted. When an alert announcement comes
on the tuned radio station or a related network station,
you will hear it, even if the volume is muted or a
cassette tape or compact disc is playing. If the radio
tunes to a related network station for an alert
announcement, it will return to the original station when
the announcement is finished. If the cassette tape or
compact disc player is playing, play will stop for the
announcement and resume when the announcement
is finished.

Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and a
couple of reflective warning triangles. And, if you will
be driving under severe conditions, include a small bag
of sand, a piece of old carpet or a couple of burlap bags
to help provide traction. Be sure you properly secure
these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the
road probably have good traction.
However, if there is snow or ice between your tires and
the road, you can have a very slippery situation. You'll
have a lot less traction or ªgripº and will need to be
very careful.
What's the worst time for this? ªWet ice.º Very cold
snow or ice can be slick and hard to drive on. But wet
ice can be even more trouble because it may offer the
least traction of all. You can get wet ice when it's about
freezing (32
F; 0
C) and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there.

4-34
CAUTION:
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can
break, and it can change the way your vehicle
handles. These could cause you to lose control
and crash. Also, overloading can shorten the life
of your vehicle.
NOTICE:
Your warranty does not cover parts or
components that fail because of overloading.
If you put things inside your vehicle -- like suitcases,
tools, packages or anything else
-- they will go as fast as
the vehicle goes. If you have to stop or turn quickly, or
if there is a crash, they'll keep going.
CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or in
a crash.

Put things in the trunk of your vehicle. In a
trunk, put them as far forward as you can.
Try to spread the weight evenly.

Never stack heavier things, like suitcases,
inside the vehicle so that some of them are
above the tops of the seats.

Don't leave an unsecured child restraint in
your vehicle.

When you carry something inside the
vehicle, secure it whenever you can.
Electronic Level Control
This feature keeps the rear of your vehicle level as the
load changes. It's automatic
-- you don't need to
adjust anything.

4-40 Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you'll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.
Passing
You'll need more passing distance up ahead when
you're towing a trailer. And, because you're a good deal
longer, you'll need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide you.

Towing Your Vehicle
CAUTION:
To help avoid serious personal injury to you
or others:

Never let passengers ride in a vehicle that is
being towed.

Never tow faster than safe or posted speeds.

Never tow with damaged parts not
fully secured.

Never get under your vehicle after it has
been lifted by the tow truck.

Always secure the vehicle on each side with
separate safety chains when towing it.

Use only the correct hooks.

6-34
To be sure the vent hose (A) is properly attached, the
vent hose connectors (B) must be securely reattached to
the vent outlets (C) on each side of the battery, and the
vent assembly grommet (D) must be secured to the
floor pan (E).
Vehicle Storage
If you're not going to drive your vehicle for 25 days or more,
remove the black, negative (
-) cable from the battery.
This will help keep your battery from running down.
CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See ªJump Startingº 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.
Also, for your audio system, see ªTheft
-Deterrent
Featureº in the Index.
