ECO mode BUICK LESABRE 2004 Owner's Manual

In many crashes severe enough to inate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
Air bags are designed to inate only once. After an
air bag inates, you’ll need some new parts for
your air bag system. If you don’t get them, the air
bag system won’t be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
Your vehicle is equipped with an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also equipped
with a crash sensing and diagnostic module,
which records information about the frontal air bag
system. The module records information about
the readiness of the system, when the system
commands air bag ination and driver’s safety belt
usage at deployment. The module also records
speed, engine rpm, brake and throttle data.
Let only qualied technicians work on your air bag
systems. Improper service can mean that an air
bag system won’t work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, or the air
bag covering on the driver’s and right front
passenger’s seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right front
passenger’s air bag, or both the air bag module
and seatback for the driver’s and right front
passenger’s side impact air bag. Do not open or
break the air bag coverings.

Compass Operation
COMPASS:Press this button once to turn the compass
on or off.
O(On/Off):For mirrors equipped with OnStar®controls,
press this button once to turn the compass on or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for about
two seconds. After two seconds, the mirror will display
the compass heading.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two seconds, the display
does not show a compass heading (N for North, for
example), there may be a strong magnetic eldinterfering with the compass. Such interference may be
caused by a magnetic antenna mount, magnetic
note pad holder or a similar magnetic item. If the letter
C should ever appear in the compass window, the
compass may need calibration.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.
Mirrors equipped with OnStar
®controls can be placed
in calibration mode by pressing and holding the
on/off button untilaCisshown in the compass display.
Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. The mirror is
set in zone eight upon leaving the factory. It will be
necessary to adjust the compass to compensate for
compass variance if you live outside zone eight. Under
certain circumstances, as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. If not adjusted to account for compass
variance, your compass could give false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance zone
number on the following zone map.

Programming the HomeLink®
Transmitter
Do not use the HomeLink®Transmitter with any garage
door opener that does not have the “stop and reverse”
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of the
steps involved, it may be helpful to have another person
available to assist you in programming the transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on the
internet at: www.homelink.com or by calling
1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
®buttons.
2-39

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to “time out” or quit after several seconds of
transmission. This may not be long enough for
HomeLink
®to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
“time out” in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
“Programming HomeLink
®” procedures (regardless of
where you live), replace Step 3 under “Programming
HomeLink
®” with the following:
Continue to press and hold the HomeLink
®button while
you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal has
been successfully accepted by HomeLink
®. The
indicator light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming HomeLink
®”
to complete.
Using HomeLink®
Press and hold the appropriate HomeLink®button for at
least half of a second. The indicator light will come
on while the signal is being transmitted.
Erasing HomeLink®Buttons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
the indicator light begins to ash, after 20 seconds.
2. Release both buttons. Do not hold for longer than
30 seconds.
HomeLink
®is now in the train (learning) mode and can
be programmed at any time beginning with Step 2
under “Programming HomeLink
®.”
Individual buttons can not be erased, but they can be
reprogrammed. See “Reprogramming a Single
HomeLink
®Button” next.
Reprogramming a Single HomeLink®
Button
To program a device to HomeLink®using a HomeLink®
button previously trained, follow these steps:
1. Press and hold the desired HomeLink
®button. Do
not release the button.
2. The indicator light will begin to ash after
20 seconds. While still holding the HomeLink
®
button, proceed with Step 2 under “Programming
HomeLink®.”

Courtesy Lamps
If it is dark enough outside, when any door is opened,
several lamps go on. They make it easy for you to enter
and leave the vehicle. You can also turn these lamps
on by sliding the INTERIOR lever all the way to the top.
Entry Lighting
If it is dark enough outside when you press the unlock
button on the remote keyless entry transmitter, the
interior courtesy lamps will turn on and stay on for about
40 seconds. The lamps will turn off immediately by
pressing the lock button on the remote keyless entry
transmitter, turning the ignition key to RUN or activating
the power door locks.
Delayed Entry Lighting
If it is dark enough outside when you open the door, the
interior lamps will turn on. When you close the door with
the ignition off, the interior lamps will stay on for up to
25 seconds or until the ignition is turned to an on position.
When the lamps turn off as a result of the 25 second timer
or the ignition switch being turned on, the lighting will
deactivate by way of the theater dimming effect. Locking
the doors will override the delayed entry lighting feature
and the lamps will turn off right away.
Theater Dimming
This feature allows for a three to ve-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
If it is dark enough outside when you remove the key
from the ignition, the interior lamps will turn on and stay
on for about 25 seconds. This will give you time to
nd the door pull handle or lock switches. Once the key
is inserted into the ignition the exit lighting will be
cancelled and the lighting will fade out.
Perimeter Lighting
If it is dark enough outside when the unlock button on
the remote keyless entry transmitter is pressed, the
DRL, parking lamps and back-up lamps will come on.
Personal Choice Programming
This feature can be programmed in the on or off mode
for each transmitter.
If your vehicle is equipped with the Driver Information
Center (DIC), you must use it to program this feature.
SeeDriver Information Center (DIC) on page 3-45.
To turn the feature off, do the following:
1. Close all the doors and turn the ignition on. Keep
all doors closed throughout this procedure.
2. Press and hold LOCK on the power door lock
switch throughout this procedure. All the doors

Also in this mode, the RECIRC function is activated to
create the maximum cooling effect in the vehicle. If
RECIRC was activated before selecting MAX, the light
in the RECIRC button will go off. If RECIRC is
selected after MAX, the light in the RECIRC button will
not come on.
NORM (Normal Air Conditioning):This mode cools
the outside air entering your vehicle and directs it
through the instrument panel outlets.
BI-LEV (Bi-Level Air Conditioning):This mode directs
about half of the air to the instrument panel outlets,
and then directs most of the remaining air to the oor
outlets. Some air may be directed toward the windshield.
Cooler air is directed to the upper outlets and warmer
air to the oor outlets. The air conditioning compressor is
on in this mode.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select MAX.
4. Select the coolest temperature.
5. Select the highest fan speed.Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside of your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments to the temperature, the fan
speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
center of the instrument panel, near the windshield,
or the system will not work properly.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. This mode allows you to clear fog or
frost from your windshield.
3-25

Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode and the fan speed.
1. Press the AUTO button.
2. Adjust the temperature to 75° F (24° C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest
temperature setting, the system will remain in
manual mode at that temperature and it will not go
into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.
Manual Operation
Pressing the FAN or AIR FLOW buttons cancels
automatic operation and places the system in manual
mode. Press the AUTO button to return to automatic
operation.
