2006 Buick LaCrosse Owner ManualM

Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see “Seats” in the Index.
3. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, seeSafety Belt
Extender on page 1-30.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
1-16

To unlatch the belt, just push the button on the buckle.
The belt should go back out of the way.
Before you close the door, be sure the belt is out of
the way. If you slam the door on it, you can damage
both the belt and your vehicle.
Shoulder Belt Height Adjustment
Before you begin to drive, move the shoulder belt height
adjuster to the height that is right for you.
Adjust the height so that the shoulder portion of the belt is
centered on your shoulder. The belt should be away from
your face and neck, but not falling off your shoulder.
Incorrect positioning of the shoulder belt can reduce
the effectiveness of the safety belt.
To move it down, press
down on the release lever
(A) and move the height
adjuster to the desired
position. You can move
the height adjuster up
just by pressing up on
the shoulder belt guide.
After you move the height adjuster to where you want it,
try to move it down without squeezing the release
lever to make sure it has locked into position.

{CAUTION:
If something is between an occupant and an
airbag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating airbag must be kept clear. Do not put
anything between an occupant and an airbag,
and do not attach or put anything on the
steering wheel hub or on or near any other
airbag covering. And, if your vehicle has
roof-mounted side impact airbags, never
secure anything to the roof of your vehicle
by routing the rope or tiedown through any
door or window opening. If you do, the path
of an inating side impact airbag will be
blocked. The path of an inating airbag
must be kept clear.
When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal or
near-frontal crashes. But they are designed to inate only
if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account a
variety of desired deployment and non-deployment
events and are used to predict how severe a crash is
likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags will
or should deploy is not based on how fast your vehicle is
traveling. It depends largely on what you hit, the direction
of the impact and how quickly your vehicle slows down.
In addition, your vehicle has “dual-stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle has electronic frontal sensors which help the
sensing system distinguish between a moderate frontal
impact and a more severe frontal impact. For moderate
frontal impacts, these airbags inate at a level less than
full deployment. For more severe frontal impacts, full
deployment occurs. If the front of your vehicle goes
straight into a wall that does not move or deform, the
threshold level for the reduced deployment is about
12 to 16 mph (19 to 26 km/h), and the threshold level
for a full deployment is about 18 to 22 mph
(29 to 35.5 km/h).

Section 2 Features and Controls
2-1

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.

pressed again within ve seconds from the previous
press of the lock button. See “FOB LOCK FEEDBACK”
underDIC Vehicle Personalization on page 3-75for
additional information. If the vehicle has the content
theft-deterrent system, pressing the lock button may also
arm it. SeeContent Theft-Deterrent on page 2-18.
"(Unlock):Press the unlock button to unlock the
driver’s door. If the button is pressed again within
ve seconds, all remaining doors will unlock. The interior

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.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can easily
open the doors and fall out of a moving
vehicle. When a door is locked, the handle
will not open it. You increase the chance of
being thrown out of the vehicle in a crash if
the doors are not locked. So, wear safety
belts properly and lock the doors whenever
you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
CAUTION: (Continued)
