Resynchronization
Resynchronization may be necessary due to the security
method used by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal
it has been sent previously.
This prevents anyone from recording and playing back
the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and simultaneously press and hold the
LOCK
and UNLOCK buttons on the transmitter for not more
than five seconds. The door locks should cycle to
confirm synchronization.
If the locks do not cycle, see
your retailer for service.
Liftgate
It can be dangerous to drive with the rear
window or liftgate open because carbon
monoxide
(CO) gas can come into your vehicle.
You can’t see or smell CO. It can cause
unconsciousness and even death.
If you must drive with the rear window or liftgate
open or if electrical wiring or other cable
connections must pass through the seal between
the body and the rear window or liftgate:

system to its highest speed with the setting

Turn and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow
you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the
turn is finished, the lever will return automatically.
An arrow on
the instrument
panel will flash in the
direction of the turn or
lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there
until you
complete your lane change. The lever will return by
itself when you release it.
As you signal a turn or a lane change, if the arrows don't
flash but just stay on,
a signal bulb may be burned out
and other drivers won't see your
turn signal. If
a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at
all when you
signal
a turn, check the fuse (see "Fuses and Circuit
Breakers"
in the Index) and for burned-out bulbs.
If you have
a trailer towing option with added wiring for
the trailer lamps, a different turn signal flasher is used.
With this flasher installed, the signal indicator will flash
even if a turn signal bulb is burned out. Check the front
and rear turn signal lamps regularly to make sure they
are working.
Headlamp HighLow Beam Changer
To change the headlamps from low to high-beam or
high to low-beam,
pull the multifunction lever all the
way toward you. Then release
it.
When the high beams are
on, this indicator light on
the instrument panel will
also be on.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows
AIR BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells
you if there is an electrical problem. The system
check includes
the air bag sensors, the air bag module,
the wiring and the diagnostic module.
For more
information on the air bag system, see
“Air Bag” in
the Index.
AIR
BAG
This light will come on
when you start your engine,
and
it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may
not work properly. Have your vehicle
serviced right away. The air
bag readiness light should flash for a few
seconds when you turn the ignition key to
RUN. If the
light doesn’t come on then, have
it fixed so it will be
ready
to warn you if there is a problem.
Charging System Indicator Light
The charging system light
will come on briefly when
you turn on the ignition, but
the engine is not running,
as a check
to show you it
is working.
It should go out once the engine is running. If it stays
on, or comes
on while you are driving, you may have a
problem with the charging system.
It could indicate that
you have problems with a generator drive belt, or
another electrical problem. Have
it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.

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.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring and a heavy-duty turn signal flasher (included
in
the optional trailering package).
The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you’re about to
turn, change lanes or stop.
When towing
a trailer, the arrows on your instrument
panel will flash for turns even
if the bulbs on the trailer
are burned out. Thus,
you may think drivers behind you
are seeing your signal when they are not. It’s important
to check occasionally to be sure the trailer bulbs are
still working.

Trailer Wiring Harness
The light duty trailer wiring is a six-wire harness
assembly. The optional heavy-duty trailer wiring is an
eight-wire harness assembly. The harnesses are stored
under the vehicle,
on the driver’s side corner frame
crossmember. The heavy-duty trailer wiring has
a
30-amp feed wire with an inline fuse located by the
junction block. See “Fuses and Circuit Breakers”
in the
Index. Both harnesses have no connector and should be
wired by
ilt qualified electrical technician. The technician
can use the following color code chart when connecting
the wiring harness to your trailer.
Dark Blue: Use for electric trailer brakes or
auxiliary wiring.
Red: Use for battery charging: it connects to the
starter solenoid (eight-wire harness only).
Light Green: Back-up lamps (eight-wire
harness only).
Brown: Taillamps and parking lamps.
Yellow: Left stoplamp and turn signal.
Dark Green: Right stoplamp and turn signal.
0 White (Heavy Gage): Ground wire.
White (Light Gage): Auxiliary stoplamp.
Securely attach the harness to the trailer, then tape or
strap
it to your vehicle’s frame rail. Be sure you leave it
loose enough so the wiring doesn’t bend or break, but
not
so loose that it drags on the ground. Store the
harness
in its original place. Wrap the harness together
and tie
it neatly so it won’t be damaged.

Electrical System
Add-on Electrical Equipment
I NOTICE:
Don’t add anything electrical to your Oldsmobile
unless you check with your retailer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can
keep other components from working
as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your Oldsmobile, see
“Servicing Your Air Bag-Equipped Oldsmobile”
in
the index.
Headlamps
The headlamp wiring is protected by an internal circuit
breaker.
An electrical overload will cause the lamps to
go on and off, or in some cases to remain off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker
and a fuse. If the motor overheats due to heavy
snow, etc., the wiper
will stop until the motor cools. If
the overload is caused by some electrical problem, be
sure
to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load
is too heavy,
the circuit breaker opens and closes, protecting the
circuit
until the problem is fixed or goes away.

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers,
and fusible thermal links. This greatly reduces the
chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the
band
is broken or melted, replace the fuse. Be sure you
replace a bad fuse
with a new one of the identical size
and rating.
If you ever have a problem on the road and don’t have a
spare fuse, you can borrow one that has the
same
amperage. Just pick some feature of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace
it as soon as you can.
Instrument Panel Fuse Block
The fuse block is at the
driver’s end
of the
instrument panel.
Remove the cover by turning the fastener
counterclockwise. Extra fuses and
the fuse extractor are
provided
in the cover. To reinstall the fuse panel cover,
push
in and turn the fastener clockwise.
