2005 BUICK LACROSSE battery replacement

This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
The vehicle’s doors can be locked and unlocked, and
the trunk can be unlatched from about 3 feet (1 m) up to
60 feet (18 m) away with the remote keyless entry
transmitter.
If your vehicle has the remote start feature you can also
start your vehicle with the remote keyless entry
transmitter. Your remote keyless entry transmitter, with
the remote start button, provides an increased range
of operation. You can start your vehicle from an average
range of 492 feet (150 m) away. However, the range
may be less while the vehicle is running and you
may need to be closer to your vehicle to turn it off than
you were to turn it on.
There are other conditions which can affect the
performance of the transmitter. SeeRemote Keyless
Entry System on page 2-3.

V(Remote Trunk Release):Press this button to
release the trunk lid. The transaxle must be in PARK (P)
for this feature to operate.
L(Remote Alarm):Press this button to activate an
alarm. The ignition must be in off or accessory for
the alarm to work. When the alarm button is pressed,
the headlamps will ash and the horn will sound
repeatedly for two minutes. The alarm will turn off when
the ignition is moved to RUN or the alarm button is
pressed again.
Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry 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 GM dealer. Remember to
bring any additional transmitters so they can also
be re-coded to match the new transmitter. Once your
dealer has coded the new transmitter, the lost
transmitter will not unlock your vehicle. The vehicle can
have a maximum of four transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is probably time to change the battery.
The KEY FOB BATT LOW message in the vehicle’s
DIC will display if the remote keyless entry transmitter
battery is low.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.

Battery
Your vehicle has a maintenance free battery. When it is
time for a new battery, get one that has the replacement
number shown on the original battery’s label. We
recommend an ACDelco
®replacement battery. See
Engine Compartment Overview on page 5-12for
battery location.
Warning:Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
If the battery has a very low charge or is dead, you may
not be able to remove the ignition key from the ignition
switch or shift out of PARK (P). Refer toShifting
Out of Park (P) on page 2-29.
Vehicle Storage
If you are not going to drive your vehicle for 25 days
or more, remove the black, negative (−) cable from
the battery. This will help keep the battery from
running down.
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
are not careful. SeeJump Starting on
page 5-39for tips on working around a battery
without getting hurt.
