2001 BUICK LESABRE ECO mode

1-27
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inflate (if battery power is available). You can lock
the doors again and turn the interior lamps off by using
the door lock and interior lamp controls.
In many crashes severe enough to inflate 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 inflate only once. After an
air bag inflates, 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
inflation and driver's safety belt usage at
deployment. The module also records speed,
engine rpm, brake and throttle data.

Let only qualified 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.

2-7 Central Door Unlocking System

are on and the ignition switch is turned to RUN, the
wiper

switch on, remove the key from the ignition and open
the driver's door, you will hear a continuous warning
chime. The chime will turn off when the lamps are
turned off.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lights are required on all vehicles first sold
in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel, so be sure it isn't covered.
The DRL system will make your high
-beam headlamps
turn on at reduced brightness in daylight when the
following conditions are met:

The ignition is on,

the headlamp switch is off and

the transaxle is not in PARK (P).

2-48 Delayed Exit Lighting

key from the ignition, the interior lamps will turn on
and stay on for approximately 25 seconds. This will
give you time to find 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
theater dim.
Perimeter Lighting

Battery Load Management
The battery load management feature is designed to
monitor the vehicle's electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at
a higher rpm setting than normal to make sure the
battery charges. High electrical loads may occur when
several of the following are on: headlamps, high beams,
rear window defogger, high blower fan, heated seats
(if equipped) and engine cooling fans.
If your vehicle's battery remains in a heavy discharge
condition for a long period of time, the blower fan,
rear defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Exterior Lighting Battery Saver
If the manual lamp control has been left on, the exterior
lamps will turn off approximately 10 minutes after the
ignition is turned to LOCK and any door has been
opened. This protects draining the battery in case you
have accidentally left the headlamps or parking lamps
on. If you need to leave the lamps on for more than
10 minutes, use the manual control to turn the lamps
back on after the ignition is turned to LOCK and any
door is opened. To delay the lamps from turning off,
see ªTwilight Sentinel

º in the index.
