Should interference to this system occur, try this:
Check to determine if battery replacement is necessary. See
the instructions on battery replacement later in this section.
Check the distance. You may be too far from your
vehicle. This product has
a maximum range.
Check the location. Other vehicles or objects may be
blocking the signal.
See your Buick dealer or a qualified technician for
service.
Changes or modifications to this system by other than an
authorized service facility could void authorization to use
this equipment.
Operation
The driver’s door will unlock and the interior lights will
go on when “UNLOCK’ is pressed. If pressed again
within five seconds, all doors will unlock. The interior
lights will
go out after 40 seconds or when you turn on
the ignition.
All doors will lock when “DOOR” is pressed.
The trunk or liftgate will unlock when the opened trunk
symbol is pressed, but only when the transaxle is in
“P”
(Park). On the wagon the ignition must also be in the
“Off” position.
Matching Transmitter(s) to Your Vehicle
Each key chain transmitter is coded to prevent another
transmitter from unlocking your vehicle.
If a transmitter
is lost or stolen, a replacement can be purchased through
your dealer. Remember to bring the remaining
transmitter with you when you
go to your dealer. When
the dealer matches the replacement transmitter to your
vehicle, the remaining transmitter must also be matched. Once the new transmitter is coded, the lost transmitter
will not unlock your vehicle.
You can match a transmitter to as many different vehicles
as you own, provided they are equipped with
exactly the
same model system.
(General Motors offers several
different models of these systems on their vehicles.) Each
vehicle can have only two transmitters matched to it. See
your dealer to match transmitters to another vehicle.
Battery Replacement
Under normal use, the batteries in your key chain
transmitter should last about
two years.
You can tell the batteries are weak if the transmitter won’t
work at the normal range in any location.
If you have to
get
close to your vehicle before the transmitter works, it’s
probably time to change the batteries.

Headlight “On” Warning
If you open the door while leaving the lights on, you will
hear a warning chime.
Daytime Running Lights (Canada Only)
The Canadian Federal Government has decided that “Daytime Running Lights” (DRL)
are a useful feature, in
that DIU can make your vehicle more visible to
pedestrians and other drivers during daylight hours. DRL
are required on new vehicles sold in Canada.
Your DRL work with a light sensor on top
of the
instrument panel. Don’t cover it up. The low beam
headlights will come on at reduced brightness
in daylight
when:
The ignition is on
The headlight switch is off, and
The parking brake is released.
At dusk, the exterior. lights will come bn &.nomatically
and the low
beams will change to full brightness. At
dawn, the exterior lights will go out and the low beams
will change to
the reduced brightness of DRL (if the
headlight switch is off).
Of course, you may still turn on the headlights any time
you need to.
To idle your vehicle with DRL off, set the parking brake
while the ignition is in the
“Off’ or “Lock” position.
Then start the vehicle. The
DRL will stay off until you
release the parking brake.
Map Light
& Press the switch to turn the
map light on and
off.

Your Buick Comfort Control
Syst m -
The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also
has the flow-through ventilation system described later in
this section.
Lever Controls: The upper lever changes the functions
of your system. The lower lever changes the temperature
of the air coming through the system.
3f : Selects the force of air you want.
Air Conditioning
The upper lever has three air conditioner settings. On
very hot days, open the windows long enough to let hot
inside air escape.
This reduces the amount of work your
air conditioner's compressor
will have to do, which
should help fuel economy.
MAX: Provides maximum cooling with the least amount
of work. This setting recirculates much of the air inside
your vehicle
so it maximizes your air conditioner's
performance and
fuel economy.
NORM (Normal): Use for normal cooling on hot days.
This setting cools outside air and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use this on cool, but sunny days.
This setting brings in the outside air, but directs it in two\

ways. The cool air
is directed to the upper portion of
your body through the instrument panel
outlets, but
warmed air is directed through the heater ducts and
defroster vents. At times
this temperature difference may
be more apparent than others.
To turn the 5x1 off, move the upper lever to the OF'F position.

REVERSIBLE LANE ON MULTILANE ROADWAY
Many city roads and expressways, and even bridges, use
reversible-lane traffic control during rush hours. A red
X
light above a lane means no driving in that lane at that
time. A green arrow means you may drive in that lane.
Look for the signs posted to warn drivers what hours and
days these systems are in effect.
Pavement Markings
NO PASSING ZONE
Pavement markings add to traffic signs and signals. They
give information to drivers without taking attention from
the roadway. A solid yellow line on your side
of the road
or lane means “Don’t Cross:’
Your Own Signals
Drivers signal to others, too. It’s not only more polite, it’s
safer to let other drivers know what you are doing. And
in some places the law requires driver signals.
Turn and lane change signals. Always signal when you
plan to turn or change lanes.
