To program the new key:
1. 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.
2. After the engine has started, turn the key to OFF, and
remove the key.
3. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
4. The SECURITY telltale 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.
5. Repeat 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 restart 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.
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the long
run if you follow these guidelines:

Don't drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.

SERVICE STABILITY SYSTEM - 54: If you ever
see the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system (stop; turn off the engine; then start the
engine again). If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem. You
should see your dealer for service. Reduce your speed
and drive accordingly.
STABILITY SYSTEM ACTIVE
- 55: You may see
the STABILITY SYSTEM ACTIVE message on the
Driver Information Center. It means that an advanced,
computer
-controlled system has come on to help your
vehicle continue to go in the direction in which you're
steering. This stability enhancement system activates when
the computer senses that your vehicle is just starting to
spin, as it might if you hit a patch of ice or other slippery
spot on the road. When the system is on, you may hear a
noise or feel a vibration in the brake pedal. This is normal.
When the STABILITY SYSTEM ACTIVE message is
on, you should continue to steer in the direction you
want to go. The system is designed to help you in bad
weather or other difficult driving situations by making
the most of whatever road conditions will permit. If the
STABILITY SYSTEM ACTIVE message comes on,
you'll know that something has caused your vehicle to
start to spin, so you should consider slowing down.
DIC Personal Choice Programming
The DIC can be used to program the following personal
choice features available with your vehicle:

Automatic Door Locks

Window Lockout

Security Feedback

Delayed Locking

Perimeter Lighting

Memory Seats

Tilt Mirrors (If Equipped)

Driver ID ON/OFF
For vehicles not equipped with a DIC, see
ªPersonal Choice Programmingº in the Index.
The personal choice settings displayed on the
DIC are determined by the transmitter used to enter
the vehicle. Each remote keyless entry transmitter was
pre
-programmed to belong to DRIVER 1 or DRIVER 2
and is numbered on the back. After the button with the
unlock symbol on a remote keyless entry transmitter is
pressed and the ignition is in RUN, the DIC will display
the identified driver and recall the settings previously
programmed for that driver. The settings can also be
recalled by briefly pressing one of the MEMORY
buttons located on the driver's door.

Winter Driving
Here are some tips for winter driving:

Have your vehicle in good shape for winter.

You may want to put winter emergency supplies in
your trunk.
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.

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 is automatic
-- you do not need to
adjust anything.

4-37 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.

5-22 Removing Wheel Covers and
Wheel Nut Caps
1. If your vehicle has an aluminum wheel with a center
cover that hides the wheel nuts, remove the center cover
by using the flat end of the wheel wrench to pry it off.
If your vehicle has a wheel cover, remove it by using
the flat end of the wheel wrench.
Pry along the edge of the wheel cover until it
comes off.
2. If your vehicle has this
aluminum wheel, you
may have plastic wheel
nut caps. Use the wheel
nut wrench to remove
the wheel nut caps and
to loosen the wheel nuts.
3. When reinstalling the decorative nut caps, tighten the
caps snugly with the wheel wrench, then continue
one
-quarter rotation to secure plastic caps.
