2007 BUICK LACROSSE battery

Read the instructions completely before attempting
to program the transmitter. Because of the steps
involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Be sure to keep the original remote control
transmitter for use in other vehicles, as well as, for
future programming. You only need the original
remote control transmitter for xed code
programming. It is also recommended that upon
the sale or lease termination of the vehicle,
the programmed buttons should be erased for
security purposes. See “Erasing your Universal
Home Remote Buttons” later in this section.
Be sure that people and objects are clear of the
garage door or security device you are
programming. When programming a garage door,
it is advised to park outside of the garage.If you do not know if your garage door opener is a
xed code or rolling code device, open your
garage door opener’s remote control battery cover.
Your garage door opener is a xed code device
if there is a panel of switches. If not, your
garage door opener is a rolling code device.

Programming Universal Home
Remote — Fixed Code
Fixed Code garage door openers are used for
garage doors produced prior to 1996. Fixed code
uses the same coded signal every time, which
is manually programmed by setting DIP switches
for a unique personal code.
To program up to three channels,
1. Remove the battery cover of the hand-held
transmitter.
2. Write down the eight to 12 coding switch
settings from left to right. When the switch
is in the up position, write “on,” and when a
switch is in the down position, write “off”.
If a switch is set between the up and down
position, write “middle”.

When it is dark enough outside, the DRL will turn
off and the vehicle’s headlamps and parking
lamps will turn on. The other lamps that come on
with the headlamps will also come on.
When it is bright enough outside, the headlamps
will go off and the DRL will come on.
To idle the vehicle with the DRL off, turn the
exterior lamp control off and then do one of the
following:
Turn the exterior lamp control to the parking
lamp position.
Turn the exterior lamp control to the
headlamp position.
Turn the exterior lamp control from AUTO to
off and back to AUTO.
This feature is not available for vehicles rst sold
in Canada.
To turn off the automatic headlamp feature when it
is dark outside, move the exterior lamp control
to the parking lamp position. The parking lamps
remain on and the headlamps turn off. The
fog lamps also go on if they were on previously.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Fog Lamps
If your vehicle has fog
lamps, the button is
located in the center of
the exterior lamps
control on the left side
of the steering column.
Press the fog lamps button to turn the lamps
on or off.
While the high-beam headlamps are on, the fog
lamps are off.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left
on after the ignition has been turned to off, the
exterior lamps will turn off after about 10 minutes.
This protects the battery from being drained.
Use the exterior lamp control to turn the lamps
back on, if they are still needed.

Perimeter Lighting
Perimeter lighting provides a period of exterior
vehicle lighting. Perimeter lighting activates when
the key is removed from the ignition or the vehicle is
unlocked using the Remote Keyless Entry (RKE)
transmitter. The amount of time the exterior lamps
will remain on can be programmed using the Driver
Information Center (DIC). See “EXIT LIGHT
DELAY” underDIC Vehicle Personalization on
page 229for additional information.
Overhead Console Reading Lamps
Your vehicle may have reading lamps located
on the overhead console. Press the lens to turn
them on and off.
Rear Assist Handle Reading Lamps
Your vehicle may have reading lamps located
near the rear assist handles. Press the lens to turn
them on and off.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC), you
may see the voltage move up or down. This is
normal. If there is a problem, an alert will be
displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very high
electrical loads.
163

A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, the Driver
Information Center (DIC) message might display
Battery Saver Active. If this message is displayed,
it is recommended that the driver reduce the
electrical loads as much as possible. See
DIC Warnings and Messages on page 208.Battery Run-Down Protection
This helps prevent the vehicle’s battery from
draining in case the interior courtesy lamps,
reading lamps, trunk lamp, underhood lamp, glove
box lamps, or sun visor vanity lamps, if equipped,
are accidently left on. If any of these lamps
are left on while the ignition is off, they will
automatically turn off after 10 minutes. The lamps
will not come back on again until one of the
following occurs:
The ignition is turned on.
The interior lamps control is turned off, then to
door or on.
Ultrasonic Rear Parking
Assist (URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help
you park while in REVERSE (R) and operates only
at speeds less than 3 mph (5 km/h). URPA can help
you avoid colliding with objects such as parked
vehicles. The system can detect objects 5 feet
(1.5 m) behind your vehicle and tell you how close
those objects are to your rear bumper.
164

Accessory Power Outlet(s)
The accessory power outlets enable power
electrical equipment such as a cellular telephone
or a CB radio to be used inside the vehicle.
Your vehicle has 12-volt outlets. One outlet is
located on the center console below the climate
controls. There may be another outlet located
inside the center storage console or in the ip and
fold console.
Open the cover to use the outlet. Be sure to close
the cover when the outlet is not in use.
Notice:Adding any electrical equipment to
your vehicle may damage it or keep other
components from working as they should. The
repairs would not be covered by your warranty.
Do not use equipment exceeding maximum
amperage rating of 20 amperes. Check with
your dealer before adding electrical equipment.Certain power accessory plugs may not be
compatible to the power accessory outlet and
could result in blown vehicle or adapter fuses.
If you experience a problem, see your dealer.
Notice:Improper use of the power outlet can
cause damage not covered by your warranty.
Do not hang any type of accessory or
accessory bracket from the plug because the
power outlets are designed for accessory
power plugs only.
Notice:Leaving electrical equipment plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.
When adding electrical equipment, be sure to
follow the proper installation instructions included
with the equipment.
