Training a Garage Opener with a “Rolling
Code” Feature
If you programmed the universal transmitter, but the
garage door will
not open, and if your garage door opener
was manufactured after 1995, your garage door may have
a security feature that changes
the “code” of your garage
door opener every time it is opened or closed.
To determine if your garage door opener has this
“rolling code” feature, press the appropriate button on
the universal transmitter that was programmed. If the
red light flashes rapidly for
one to two seconds, then
turns solid, your garage door opener has this feature.
To program a garage door opener with the rolling code
feature, do
the following:
1. Program your hand-held transmitter to the universal
transmitter by following the steps provided under
“Programming
the Transmitter” earlier in this section.
2.
3.
4.
5.
6.
Remove the cover panel from the garage door opener
receiver.
It is located near the garage door opener motor.
Locate the training button
on the garage door opener
receiver. The exact location and color will vary
among brands.
Press the training button
on the garage door opener
receiver for one to two seconds.
Return to your vehicle and press the programmed
button on the universal transmitter until the red light
flashes rapidly (about two seconds).
Release the button, then press it again
to confirm it
was programmed
to the garage door opener receiver.
You may now use either the universal transmitter or the
hand-held transmitter to open your garage door.
If you
still have difficulty in programming and require
assistance, please call
1-800-355-35 15.
Accessories
Accessories for the universal transmitter are available
from
the manufacturer of the unit. If you would like
additional information, please call

Understanding Radio Reception
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.
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.
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.
To help avoid hearing loss or damage:
Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably
and clearly.
.
NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you can add
what you want.
If’ you can, it’s very important to
do
it properly. Added sound equipment may
interfere with the operation
of your vehicle’s
engine, Delco radio
or other systems, and even
damage them. Your vehicle’s systems may interfere
with the operation
of sound equipment that has
been added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check Federal rules
covering mobile radio and telephone units.

Downloaded from www.Manualslib.com manuals search engine 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 vehicle. 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
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 “grip” and will need to be
very careful.

Downloaded from www.Manualslib.com manuals search engine I A 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, 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.
Using heavier suspension components to get added
durability might
not change your weight ratings. Ask
your dealer
to help you load your vehicle the right way.
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.
I
Things you put inside your vehicle can strik
injure people in
a sudden stop or turn, or in a crash.
0 Put things in the cargo area of your vehicle.
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.
0 When you carry something inside the
vehicle, secure it whenever you can.
0 Don’t leave a seat folded down unless you
need to.

Downloaded from www.Manualslib.com manuals search engine 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.
Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal. Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
