security, it can be a problem if the remote keyless entry
transmitter is damaged, lost or if it fails to operate for
any reason while the content theft

armed. The content theft
-deterrent system must be
disarmed for the engine to run and while in Mode 2,
the key can no longer disarm the system.

that matches the mode you want.
6. Remove the key from the door key cylinder.
The mode you selected is now set. You can either exit
the programming mode by following the instructions
earlier in this section or program the next feature
available on your vehicle.

PASS-Key
III
Your vehicle is equipped
with the PASS
-Key III
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key III is a passive
theft
-deterrent system. This
means you don't have to do
anything different to arm or
disarm the system. It works
when you insert or remove
the key from the ignition.
Your PASS
-Key III system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this
device must accept any interference received, including
interference that may cause undesired operation of
the device.
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
PASS
-Key III uses a radio frequency transponder in the
key that matches a decoder in your vehicle.
When the PASS
-Key III system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. The starter will not work and fuel will
stop being delivered to the engine. Anyone using a
trial
-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
When trying to start the vehicle if the engine does not
start and the SECURITY light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.

2-28
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse (see ªFuses and
Circuit Breakersº in the Index). If the engine still does
not start with the other key, your vehicle needs service.
If your vehicle does not start, the first key may be faulty.
See your dealer or a locksmith who can service the
PASS
-Key III to have a new key made.
It is possible for the PASS
-Key III decoder to learn the
transponder value of a new or replacement key. Up to
10 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 key blank that is cut exactly
as the ignition key that operates the system.To program the new key:
1. Insert the black master ignition key 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 5 seconds of removing the original key.
4. 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.
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 your PASS
-Key III key, see your
dealer or a locksmith who can service PASS
-Key III to
have a new key made.

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.

4-33
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.
Towing a Trailer
CAUTION:
If you don't use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
You may also damage your vehicle; the resulting
repairs would not be covered by your warranty.
Pull a trailer only if you have followed all the
steps in this section. Ask your dealer for advice
and information about towing a trailer with
your vehicle.
Do not tow a trailer if your vehicle is equipped with the
3800 (L67) Supercharged engine.

4-37 Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer so that the tongue will not drop to the road
if it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer's recommendation for attaching safety
chains and do not attach them to the bumper. Always
leave just enough slack so you can turn with your rig.
And, never allow safety chains to drag on the ground.
Trailer Brakes
Because you have anti-lock brakes, do not try to tap into
your vehicle's brake system. If you do, both brake
systems won't work well, or at all.
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.
