2. Remove the battery and replace it with the new
3. Put the two halves back together. Make sure the
cover
is on tightly, so water won’t get in.
4. Check the operation of the transmitter with your
vehicle. If the transmitter does not
work, try
synchronizing the transmitter with the receiver.
Synchronization
Your Remote Lock Control system is equipped with a
security system that prevents anyone from recording
and playing back your signal. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal that has been sent to it more
than once.
To resynchronize your transmitter and receiver, follow
these directions:
1.
2.
3.
Stand close to your vehicle.
Press and hold the
LOCK and UNLOCK buttons on
the transmitter at the same time.
Hold the buttons for five seconds. In this time, the
doors should lock and unlock once. This confirms
the resynchronization. If the doors do not lock and
unlock, see your retailer for service.

Your vehicle is equipped with the Passlock
theft-deterrent system. During normal
operation, the SECURITY light will
go
off after the engine is started.
If the engine stalls
and the SECURITY light flashes,
wait until the light stops flashing before trying to restart
the engine. Remember to release the key from the
START position as soon as the engine starts.
If you are driving and the SECURITY light comes
on, you will be able to restart the engine if you turn
the engine
off. However, your Passlock system is
not working properly and must be serviced by your
retailer. Your vehicle is not protected by Passlock at this
time. You may also want to check the fuse (see “Fuses
and Circuit Breakers” in the Index). See your retailer
for service.
If the SECURITY light comes on while the engine is
running, a problem has been detected and the system
may need service. See your retailer for service.
In an emergency, call the Oldsmobile Roadside
Assistance Center at
1-800-442-OLDS (6537).
Passlock is a passive theft-deterrent system. The system
is armed once the key is removed from the ignition.
Passlock enables fuel
if the ignition lock cylinder is
turned with a valid key. If a correct key is not used,
fuel is disabled.

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 (1 6 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to come and go.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until
it is too late. Your hearing can adapt to higher
volumes
of sound. Sound that seems normal can be
loud and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to it.

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.
4-25

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, or
it can change the way your vehicle
handles. These could cause you to lose control.
Also, overloading can shorten the life of
your vehicle.
I NOTICE:
Your warranty does not cover parts or
components that fail because
of overloading. Things
you put inside your vehicle can strike
and injure people in a sudden stop or turn, or in
a crash.
0 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.
Don’t leave a seat folded down unless you
need to.

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.
