2005 Buick Terraza Owner ManualM

Q:What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A:Move the child toward the center of the vehicle,
but be sure that the shoulder belt still is on the
child’s shoulder, so that in a crash the child’s upper
body would have the restraint that belts provide.
If the child is sitting in a second row position,
seeRear Safety Belt Comfort Guides for Children
and Small Adults on page 1-31.
{CAUTION:
Never do this.
Here a child is sitting in a seat that has a
lap-shoulder belt, but the shoulder part is
behind the child. If the child wears the belt in
this way, in a crash the child might slide under
the belt. The belt’s force would then be applied
right on the child’s abdomen. That could cause
serious or fatal injuries.
Wherever the child sits, the lap portion of the belt
should be worn low and snug on the hips, just touching
the child’s thighs. This applies belt force to the child’s
pelvic bones in a crash.

Child Restraint Systems
An infant car bed (A), a special bed made for use in a
motor vehicle, is an infant restraint system designed
to restrain or position a child on a continuous at
surface. Make sure that the infant’s head rests toward
the center of the vehicle.A rear-facing infant seat (B) provides restraint with the
seating surface against the back of the infant. The
harness system holds the infant in place and, in a crash,
acts to keep the infant positioned in the restraint.

Side impact airbags are not designed to inate in frontal
or near-frontal impacts, rollovers or rear impacts,
because ination would not likely help the occupant.
A side impact airbag will only deploy on the side of the
vehicle that is struck.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, ination is determined by the
angle of the impact and how quickly the vehicle slows
down in frontal and near-frontal impacts. For side impact
airbags, ination is determined by the location and
severity of the impact.
What Makes an Airbag Inate?
In an impact of sufficient severity, the airbag sensing
system detects that the vehicle is in a crash. For both
frontal and side impact airbags, the sensing system
triggers a release of gas from the inator, which inates
the airbag. The inator, the airbag and related hardware
are all part of the airbag modules. Frontal airbag modules
are located inside the steering wheel and instrument
panel. For vehicles with side impact airbags, the airbag
modules are located in the seatback closest to the
driver’s and/or right front passenger’s door.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The airbag supplements the protection
provided by safety belts. Airbags distribute the force of
the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But the
frontal airbags would not help you in many types
of collisions, including rollovers, rear impacts, and many
side impacts, primarily because an occupant’s motion
is not toward the airbag. Side impact airbags would not
help you in many types of collisions, including frontal
or near frontal collisions, rollovers, and rear impacts,
primarily because an occupant’s motion is not toward
those airbags. Airbags should never be regarded
as anything more than a supplement to safety belts, and
then only in moderate to severe frontal or near-frontal
collisions for the driver’s and right front passenger’s
frontal airbags, and only in moderate to severe
side collisions for vehicles with a driver’s and right
front passenger’s side impact airbag.

Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or
other aftermarket equipment if your vehicle has
the passenger sensing system. SeeAdding Equipment
to Your Airbag-Equipped Vehicle on page 1-67for
more information about modications that can affect
how the system operates.
{CAUTION:
Stowing of articles under the passenger’s
seat or between the passenger’s seat cushion
and seatback may interfere with the proper
operation of the passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
airbag system. To purchase a service manual, see
Service Publications Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key
is turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are close
to an airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
The airbag system does not need regular maintenance.

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.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
From the outside, use your key or the remote keyless
entry transmitter.
To unlock the driver’s door from the outside with the
key, insert the key and turn it toward the front of
the vehicle. To lock the driver’s door from the outside
with your key, insert the key and turn it toward the rear
of the vehicle.
If your vehicle has power door locks, you may be able
to unlock all of the doors and the liftgate when you insert
the key, turn it toward the front of the vehicle, and
hold it there for one second. You may be able to lock all
of the doors when you insert the key and turn it toward
the rear of the vehicle.

Programmable Automatic
Door Locks
All of the doors will lock automatically when you move
your shift lever to a forward gear. All doors will
unlock automatically when the shift lever is moved
into PARK (P).
If someone needs to get out while you are not in
PARK (P), shift into PARK (P), or, have that person
use the manual lever or the power door lock switch.
When the door is closed again, it will lock when
the vehicle exceeds 5 mph (8 kph). Use the manual
lever or the power door lock switch to lock the door.
To change the way automatic door locks operate,
seeDIC Vehicle Personalization (Uplevel Only) on
page 3-68.
With the automatic door locks feature, you can lock
or unlock the doors at any time, either manually or
using the power door lock switches.
Lockout Protection
The lockout protection feature makes it more difficult
to lock the key in the vehicle. If the driver’s door is open
while the key is in the ignition, the door cannot be
locked with the power door lock switch.
This feature cannot guarantee that you will never be
locked out of the vehicle. If the key is not left in
the ignition, or, if the manual door lock is used, the
key could still be locked inside the vehicle. Always
remember to take the key with you.
Dual Sliding Doors
To open either sliding door from outside the vehicle, pull
the handle out and then pull the door toward the rear.
If you slide the door all the way back, the door will rest in
a detent position.
To move the door forward, you must rst pull the door
past the open detent position.
The driver’s side sliding door is designed to open only a
little if the fuel door is open. If this ever happens, do
not try to force the sliding door. Just close the driver’s
side sliding door. Then when the fuel ller door is
closed, the driver’s side sliding door can be opened
normally.
2-13

Power Sliding Door Operation
The power sliding door(s) will only open if the transaxle
is in PARK (P). The transaxle does not have to be in
PARK (P) to close the door(s).
There are several ways to open and close the power
sliding door(s).
If your vehicle has a single power sliding door,
press the bottom of the overhead console PSD
activation switch.
If your vehicle has dual power sliding doors, press
the top of the driver’s side and/or passenger’s side
overhead console PSD switch.
Press the passenger PSD activation switch. This
switch will also stop a moving door immediately.
Press the power sliding door button on the remote
keyless entry transmitter.
To manually open the power sliding door(s) while
the switch(es) are in the activation position, pull
and release the inside or outside door handle
to release the door latch. The door will fully open.
To manually close the power sliding door(s) while
the switches are in the activation position, pull the
inside or outside door handle or the edge of
the door. Move the door about 4 inches (10 cm)
toward the closed position and release it. The door
will close completely and latch.
If a power sliding door is locked, it cannot be
unlocked and opened using the overhead console PSD
activation switch(es) or the passenger PSD activation
switch(es). The power sliding door must either be
manually unlocked or unlocked using the power door
unlock switch located on the driver’s or front passenger’s
armrest, and then opened using the overhead or
passenger PSD activation switch(es).
The remote keyless entry transmitter can also be used
to open the power sliding door(s). If the vehicle is
locked, press the power sliding door button(s) and all
doors will unlock and the sliding door(s) will open.
SeeRemote Keyless Entry System Operation on
page 2-5.
If the power sliding door has been manually locked,
you must unlock the PSD before it can be opened.
