2006 BUICK LACROSSE battery location

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 operating 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 opened from approximately 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 the vehicle’s engine with the remote
keyless entry transmitter.

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.To replace the battery in the remote keyless entry
transmitter, do the following:
1. Insert a at object, with a thin edge, into the notch
located below the panic alarm button, and separate
the bottom half from the top half of the transmitter.
2. Remove the old battery. Do not use a metal object
to do this.
3. Slide the new battery into the transmitter with the
positive (+) side of the battery facing up. Use
one three-volt, CR2032 battery, or equivalent type.
4. Snap the front and the back of the transmitter
together. Make sure the cover is on tight, so water
will not get inside the transmitter.
5. Test the operation of the transmitter with the vehicle.

Shifting Out of Park (P)
Automatic Transaxle Shift Lock
This vehicle is equipped with an electronic shift lock
release system. The shift lock release is designed to:
Prevent ignition key removal unless the shift
lever is in PARK (P)
Prevent movement of the shift lever out of PARK (P)
unless the ignition is in a position other than OFF.
The shift lock is always functional except in the case
of a an uncharged or low voltage (less than 9 volt)
battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-42.
Console Shift
If your console shift cannot be moved out of PARK (P)
1. Apply and maintain the regular brakes.
2. Turn the ignition to the RUN position. SeeIgnition
Positions on page 2-23for more information.
3. Let up on the shift lever and make sure the shift
lever is pushed all the way into PARK (P).
4. Then, move the shift into the desired gear.
If you still cannot move the shift lever from PARK (P),
consult your dealer or a professional towing service.
Column Shift
If your park lock cable cannot be moved out of PARK (P)
1. Apply and maintain the regular brakes.
2. Turn the Ignition key to the ACCESSORY or RUN
position. SeeIgnition Positions on page 2-23for
more information.
3. Shift out of the PARK (P) position to the
NEUTRAL (N) position.
4. Move the vehicle to a safe location.
If you still cannot move the shift lever from PARK (P),
consult your dealer or a professional towing service.

Engine Oil
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality GM brake parts.
When you replace parts of your braking system — for
example, when your brake linings wear down and you
need new ones put in — be sure you get new approved
GM replacement parts. If you do not, your brakes may no
longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the balance
between your front and rear brakes can change — for
the worse. The braking performance you have come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.
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.
SeeEngine 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 2-33.
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 5-42for tips on working around a battery
without getting hurt.
Jump Starting
If your vehicle’s battery has run down, you may want to
use another vehicle and some jumper cables to start
your vehicle. Be sure to use the following steps to do
it safely.
5-42

4. Open the hood on the other vehicle and locate the
positive (+) and negative (−) terminal locations on
that vehicle.
You will not use your vehicle’s battery for jump
starting. It has a remote positive (+) jump starting
terminal, located on the underhood fuse block, for
that purpose. SeeEngine Compartment Overview
on page 5-12for more information on location.
To uncover the remote
positive (+) terminal, press
the tab at the bottom of
the fuse block and lift
the cover up.
Always use the remote positive (+) terminal instead
of the positive (+) terminal on the battery.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from any
underhood electric fan.
{CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engine is running.

6. Connect the red positive (+) cable to the positive (+)
terminal location on the vehicle with the dead
battery. Use a remote positive (+) terminal if the
vehicle has one.
7. Do not let the other end touch metal. Connect it
to the positive (+) terminal location on the vehicle
with the good battery. Use a remote positive (+)
terminal if the vehicle has one.8. Now connect the black negative (−) cable to the
negative (−) terminal location on the vehicle with
the good battery. Use a remote negative (−) terminal
if the vehicle has one.
Do not let the other end touch anything until the
next step. The other end of the negative (−) cable
does not go to the dead battery. It goes to a
heavy, unpainted metal engine part or to a remote
negative (–) terminal on the vehicle with the
dead battery.
9. Connect the other end of the negative (−) cable at
least 18 inches (45 cm) away from the dead battery,
but not near engine parts that move. The electrical
connection is just as good there, and the chance
of sparks getting back to the battery is much less.
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle that had the dead battery.
If it will not start after a few tries, it probably needs
service. 3.8L V6 Engine shown, 3.6L V6 Engine similar
