liftgate or a possible support strut failure. A repetitive chime will sound while the falling liftgate detection feature is operating. Remove any excess weight. If the liftgate continues to automatically close after opening, see your dealer for service before using the power liftgate.
Interfering with the power liftgate motion or manually closing the liftgate too quickly after power opening may resemble a support strut failure. This could also activate the falling liftgate detection feature. Allow the liftgate to complete its operation and wait a few seconds before manually closing the liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle during a power open or close cycle, the liftgate will automatically reverse direction and move a short distance away from the obstacle. After removing the obstruction, the power liftgate can be used again. If the liftgate encounters multiple obstacles on the same power cycle,
the power function will deactivate. After removing the obstructions, manually close the liftgate. This will allow normal power operation functions to resume.
If the vehicle is locked while the liftgate is closing, and an obstacle is encountered that prevents the liftgate from completely closing, the horn will sound as an alert that the liftgate did not close.
Pinch sensors are on the side edges of the liftgate. If an object is caught between the liftgate and the vehicle and presses against a sensor, the liftgate will reverse direction and open fully. The liftgate will remain open until it is activated again or closed manually.
Setting the 3/4 Mode
To change the position the liftgate stops at when opening:
1. Select MAX or 3/4 mode and power open the liftgate.

Reclining Seatbacks
Warning
{
Sitting in a reclined position when the vehicle is in motion can be dangerous. Even when buckled up, the seat belts cannot do their job.
The shoulder belt will not be against your body. Instead, it will be in front of you. In a crash, you could go into it, receiving neck or other injuries.
The lap belt could go up over your abdomen. The belt forces would be there, not at your pelvic bones. This could cause serious internal injuries.
For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear the seat belt properly.
Do not have a seatback reclined if the vehicle is moving.

Warning
{
A seat belt that is improperly routed, not properly attached, or twisted will not provide the protection needed in a crash. The person wearing the belt could be seriously injured. After raising the rear seatback, always check to be sure that the seat belts are properly routed and attached, and are not twisted.

Seat Belts

This section describes how to use seat belts properly, and some things not to do.
Warning
{
Do not let anyone ride where a seat belt cannot be worn properly. In a crash, if you or your passenger(s) are not wearing seat belts, injuries can be much worse than if you are wearing seat belts. You can be seriously injured or killed by hitting things inside the vehicle harder or by being ejected from the vehicle. In addition, anyone who is not buckled up can strike other passengers in the vehicle.
It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, passengers riding in these areas are more likely to be seriously injured or killed. Do not allow
Warning (Continued)
passengers to ride in any area of the vehicle that is not equipped with seats and seat belts.
Always wear a seat belt, and check that all passenger(s) are restrained properly too.
This vehicle has indicators as a reminder to buckle the seat belts. See Seat Belt Reminders 0 117.
Why Seat Belts Work
(Continued)
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
When riding in a vehicle, you travel as fast as the vehicle does. If the vehicle stops suddenly, you keep going until something stops you. It could be the windshield, the instrument panel, or the seat belts!
When you wear a seat belt, you and the vehicle slow down together. There is more time to stop because you stop over a longer distance and, when worn properly, your strongest bones take the forces from the seat belts. That is why wearing seat belts makes such good sense.
Questions and Answers About Seat Belts
Q: Will I be trapped in the vehicle
after a crash if I am wearing a seat belt?
A: You could be whether you are
wearing a seat belt or not. Your chance of being conscious during and after a crash, so you
can unbuckle and get out, is much greater if you are belted.
Q: If my vehicle has airbags, why
should I have to wear seat belts?
A: Airbags are supplemental
systems only. They work with seat belts not instead of them. Whether or not an airbag is provided, all occupants still have to buckle up to get the most protection.
Also, in nearly all states and in all Canadian provinces, the law requires wearing seat belts.
How to Wear Seat Belts Properly
Follow these rules for everyone's protection.
There are additional things to know about seat belts and children, including smaller children and infants. If a child will be riding in the vehicle, see Older Children 0 72 or Infants and Young Children 0 73. Review and follow the rules for children in addition to the following rules.
Seats and Restraints 53
It is very important for all occupants to buckle up. Statistics show that unbelted people are hurt more often in crashes than those who are wearing seat belts.
There are important things to know about wearing a seat belt properly.
.
Sit up straight and always keep your feet on the floor in front of you (if possible).
.
Always use the correct buckle for your seating position.
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
54 Seats and Restraints
.
Wear the lap part of the belt low and snug on the hips, just touching the thighs. In a crash, this applies force to the strong pelvic bones and you would be less likely to slide under the lap belt. If you slid under it, the belt would apply force on your abdomen. This could cause serious or even fatal injuries.
.
Wear the shoulder belt over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces. The shoulder belt locks if there is a sudden stop or crash.
Warning
{
You can be seriously injured, or even killed, by not wearing your seat belt properly.
Never allow the lap or shoulder belt to become loose or twisted.
Never wear the shoulder belt under both arms or behind your back.
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
{
The seat belt can be pinched if it is routed under plastic trim on the seat, such as trim around the rear seatback folding handle or side airbag. In a crash, pinched seat belts might not be able to provide adequate protection. Never allow seat belts to be routed under plastic trim pieces.
Always use the correct buckle for your seating position.
Never route the lap or shoulder belt over an armrest.
Lap-Shoulder Belt
All seating positions in the vehicle have a lap-shoulder belt.
The following instructions explain how to wear a lap-shoulder belt properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up straight. To see how, see Seatsin the Index.
Seats and Restraints 55
Warning
2. Pick up the latch plate and pull the belt across you. Do not let it get twisted.
The lap-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.
If the shoulder portion of a passenger belt is pulled out all the way, the child restraint locking feature may be engaged. See Child Restraint Systems 0 76. If this occurs, let the belt go back all the way and start again. If the locking

feature stays engaged after letting the belt go back to stowed position on the seat, move the seat rearward or recline the seat until the shoulder belt retractor lock releases.
Engaging the child restraint locking feature in the front outboard seating position may affect the passenger sensing system. See Passenger Sensing System 0 65.
3. 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, see Seat Belt Extender 0 58.
Position the release button on the buckle so that the seat belt could be quickly unbuckled if necessary.
4. To make the lap part tight, pull up on the shoulder belt.
To unlatch the belt, push the button on the buckle. The belt should return to its stowed position.
Always stow the seat belt slowly. If the seat belt webbing returns quickly to the stowed position, the retractor may lock and cannot be pulled out. If this happens, pull the seat belt straight out firmly to unlock the webbing, and then release it. If the webbing is still locked in the retractor, see your dealer.
Before a door is closed, be sure the seat belt is out of the way. If a door is slammed against a seat belt, damage can occur to both the seat belt and the vehicle.
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
Seat Belt Pretensioners
This vehicle has seat belt pretensioners for the front outboard occupants. Although the seat belt pretensioners cannot be seen, they are part of the seat belt assembly. They can help tighten the seat belts during the early stages of a moderate to severe frontal, near frontal, or rear crash if the threshold conditions for pretensioner activation are met. Seat belt pretensioners can also help tighten the seat belts in a side crash or a rollover event.
Pretensioners work only once. If the pretensioners activate in a crash, the pretensioners and probably other parts of the vehicle's seat belt system will need to be replaced. See Replacing Seat Belt System Parts after a Crash 0 59.
Do not sit on the outboard seat belt while entering or exiting the vehicle or at any time while sitting in the seat. Sitting on the seat belt can damage the webbing and hardware.
Rear Seat Belt Comfort Guides
Rear seat belt comfort guides may provide added seat belt comfort for older children who have outgrown booster seats and for some adults. When installed on a shoulder belt, the comfort guide positions the shoulder belt away from the neck and head.
Comfort guides are available through your dealer for the rear outboard seating positions. Instructions are included with the guides.
Seat Belt Use During Pregnancy
Seat belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear seat belts.
Seats and Restraints 57
A pregnant woman should wear a lap-shoulder belt, and the lap portion should be worn as low as possible, below the rounding, throughout the pregnancy.
The best way to protect the fetus is to protect the mother. When a seat belt is worn properly, it is more likely that the fetus will not be hurt in a crash. For pregnant women, as for anyone, the key to making seat belts effective is wearing them properly.

Seat Belt Extender
If the vehicle's seat belt will fasten around you, you should use it.
But if a seat belt is not long enough, your dealer will order you an extender. When you go in to order it, take the heaviest coat you will wear, so the extender will be long enough for you. To help avoid personal injury, do not let someone else use it, and use it only for the seat it is made to fit. The extender has been designed for adults. Never use it for securing child restraints. For more information on the proper use and fit of seat belt extenders see the instruction sheet that comes with the extender.

Torn or frayed seat belts can rip apart under impact forces. If a belt is torn or frayed, have it replaced immediately. If a belt is twisted, it may be possible to untwist by reversing the latch plate on the webbing. If the twist cannot be corrected, ask your dealer to fix it.
Make sure the seat belt reminder light is working. See Seat Belt Reminders 0 117.
Keep seat belts clean and dry. See Seat Belt Care 0 58.
Ensure there is not excessive dust or debris in the mechanism. If dust or debris exists in the system please see the dealer. Parts may need to be replaced to ensure proper functionality of the system.

Replacing Seat Belt System Parts after a Crash
Warning
{
A crash can damage the seat belt system in the vehicle. A damaged seat belt system may not properly protect the person using it, resulting in serious injury or even death in a crash. To help make sure the seat belt systems are working properly after a crash, have them inspected and any necessary replacements made as soon as possible.
After a minor crash, replacement of seat belts may not be necessary. But the seat belt assemblies that were used during any crash may have been stressed or damaged. See your dealer to have the seat belt assemblies inspected or replaced.
New parts and repairs may be necessary even if the seat belt system was not being used at the time of the crash.
Have the seat belt pretensioners checked if the vehicle has been in a crash, or if the airbag readiness light stays on after you start the vehicle or while you are driving. See Airbag Readiness Light 0 118.

All vehicle airbags have the word AIRBAG on the trim or on a label near the deployment opening.
For frontal airbags, the word AIRBAG is on the center of the steering wheel for the driver and on the instrument panel for the front outboard passenger.
For knee airbags, the word AIRBAG is on the lower part of the instrument panel.
For seat-mounted side impact airbags, the word AIRBAG is on the side of the seatback or side of the seat closest to the door.
For roof-rail airbags, the word AIRBAG is on the ceiling or trim.
Airbags are designed to supplement the protection provided by seat belts. Even though today's airbags are also designed to help reduce the risk of injury from the force of an inflating bag, all airbags must inflate very quickly to do their job.
Here are the most important things to know about the airbag system:
Warning
{
You can be severely injured or killed in a crash if you are not wearing your seat belt, even with airbags. Airbags are designed to work with seat belts, not replace them. Also, airbags are not designed to inflate in every crash. In some crashes seat belts are the only restraint. See When Should an Airbag Inflate? 0 62.
Wearing your seat belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Airbags are supplemental restraintsto the seat belts. Everyone in the vehicle should wear a seat belt properly, whether or not there is an airbag for that person.
Warning
{
Because airbags inflate with great force and faster than the blink of an eye, anyone who is up against, or very close to, any airbag when it inflates can be seriously injured or killed. Do not sit unnecessarily close to any airbag, as you would be if sitting on the edge of the seat or leaning forward. Seat belts help keep you in position before and during a crash. Always wear a seat belt, even with airbags. The driver should sit as far back as possible while still maintaining control of the vehicle. The seat belts and the front outboard passenger airbags are most effective when you are sitting well back and upright in the seat with both feet on the floor.

Warning (Continued)
Occupants should not lean on or sleep against the door or side windows in seating positions with seat-mounted side impact airbags and/or roof-rail airbags.
Warning
{
Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Always secure children properly in the vehicle. To read how, see Older Children 0 72 or Infants and Young Children 0 73.
There is an airbag readiness light on the instrument cluster, which shows the airbag symbol. The system checks the airbag electrical system for malfunctions. The light tells you if there is an electrical problem. See Airbag Readiness Light 0 118 for more information.

inflating 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.
Do not use seat accessories that block the inflation path of a seat-mounted side impact airbag.
Never secure anything to the roof of a vehicle with roof-rail airbags by routing a rope or tiedown through any door or window opening. If you do, the path of an inflating roof-rail airbag will be blocked.
When Should an Airbag Inflate?
This vehicle is equipped with airbags. See Airbag System 0 59. Airbags are designed to inflate if the impact exceeds the specific airbag
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
system's deployment threshold. Deployment thresholds are used to predict how severe a crash is likely to be in time for the airbags to inflate and help restrain the occupants. The vehicle has electronic sensors that help the airbag system determine the severity of the impact. Deployment thresholds can vary with specific vehicle design.
Frontal airbags are designed to inflate in moderate to severe frontal or near frontal crashes to help reduce the potential for severe injuries, mainly to the driver's or front outboard passenger's head and chest.
Whether the frontal airbags will or should inflate is not based primarily on how fast the vehicle is traveling. It depends on what is hit, the direction of the impact, and how quickly the vehicle slows down.
Frontal airbags may inflate at different crash speeds depending on whether the vehicle hits an object straight on or at an angle, and
whether the object is fixed or moving, rigid or deformable, narrow or wide.
Frontal airbags are not intended to inflate during vehicle rollovers, in rear impacts, or in many side impacts.
In addition, the vehicle has advanced technology frontal airbags. Advanced technology frontal airbags adjust the restraint according to either crash severity or occupant interaction.
Knee airbags are designed to inflate in moderate to severe frontal or near frontal impacts. Knee airbags are not designed to inflate during vehicle rollovers, in rear impacts, or in many side impacts.
Seat-mounted side impact airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact. Seat-mounted side impact airbags are not designed to inflate in frontal impacts, near frontal impacts, rollovers, or rear impacts.
Seats and Restraints 63
A seat-mounted side impact airbag is designed to inflate on the side of the vehicle that is struck.
Roof-rail airbags are designed to inflate in moderate to severe side crashes depending on the location of the impact. In addition, these roof-rail airbags are designed to inflate during a rollover or in a severe frontal impact. Roof-rail airbags are not designed to inflate in rear impacts. Both roof-rail airbags will inflate when either side of the vehicle is struck, if the sensing system predicts that the vehicle is about to roll over on its side, or in a severe frontal impact.
In any particular crash, no one can say whether an airbag should have inflated simply because of the vehicle damage or repair costs.
What Makes an Airbag Inflate?
In a deployment event, the sensing system sends an electrical signal triggering a release of gas from the inflator. Gas from the inflator fills the
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
64 Seats and Restraints
airbag causing the bag to break out of the cover. The inflator, the airbag, and related hardware are all part of the airbag module.
For airbag locations, see Where Are the Airbags? 0 61.
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.
Airbags supplement the protection provided by seat belts by distributing the force of the impact more evenly over the occupant's body.
Rollover capable roof-rail airbags are designed to help contain the head and chest of occupants in the outboard seating positions in the first and second rows. The rollover capable roof-rail airbags are designed to help reduce the risk of
full or partial ejection in rollover events, although no system can prevent all such ejections.
But airbags would not help in many types of collisions, primarily because the occupant's motion is not toward those airbags. See When Should an Airbag Inflate? 0 62.
Airbags should never be regarded as anything more than a supplement to seat belts.
What Will You See after an Airbag Inflates?
After frontal, knee, and seat-mounted side impact airbags inflate, they quickly deflate, so quickly that some people may not even realize the airbags inflated. Roof-rail airbags may still be at least partially inflated for some time after they inflate. Some components of the airbag module may be hot for several minutes. For location of the airbags, see Where Are the Airbags? 0 61.
The parts of the airbag that come into contact with you may be warm, but not too hot to touch. There may be some smoke and dust coming from the vents in the deflated airbags. Airbag inflation does not prevent the driver from seeing out of the windshield or being able to steer the vehicle, nor does it prevent people from leaving the vehicle.
Warning
{
When an airbag inflates, there may be dust in the air. This dust could cause breathing problems for people with a history of asthma or other breathing trouble. To avoid this, everyone in the vehicle should get out as soon as it is safe to do so. If you have breathing problems but cannot get out of the vehicle after an airbag inflates, then get fresh air by opening a window or a door. If you experience breathing problems following an airbag deployment, you should seek medical attention.
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
The vehicle has a feature that may automatically unlock the doors, turn on the interior lamps and hazard warning flashers, and shut off the fuel system after the airbags inflate. The feature may also activate, without airbag inflation, after an event that exceeds a predetermined threshold. After turning the ignition off and then on again, the fuel system will return to normal operation; the doors can be locked, the interior lamps can be turned off, and the hazard warning flashers can be turned off using the controls for those features. If any of these systems are damaged in the crash they may not operate as normal.
Warning
{
A crash severe enough to inflate the airbags may have also damaged important functions in the vehicle, such as the fuel system, brake and steering systems, etc. Even if the vehicle appears to be drivable after a

moderate crash, there may be concealed damage that could make it difficult to safely operate the vehicle.
Use caution if you should attempt to restart the engine after a crash has occurred.
In many crashes severe enough to inflate the airbag, windshields are broken by vehicle deformation. Additional windshield breakage may also occur from the front outboard passenger airbag.
.
Airbags are designed to inflate only once. After an airbag inflates, you will need some new parts for the airbag system. If you do not get them, the airbag system will not be there to help protect you in another crash. A new system will include airbag modules and possibly other parts. The service manual for the vehicle covers the need to replace other parts.

Whenever possible, children aged 12 and under should be secured in a rear seating position.
Never put a rear-facing child seat in the front. This is because the risk to the rear-facing child is so great, if the airbag inflates.
Warning
{
A child in a rear-facing child restraint can be seriously injured or killed if the passenger frontal airbag inflates.

Even if the passenger sensing system has turned off the front outboard passenger airbag(s), no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though the airbag(s) are off.
Never put a rear-facing child restraint in the front seat, even if the airbag is off. If securing a forward-facing child restraint in the front outboard passenger seat, always move the seat as far back as it will go. It is better to secure child restraints in the rear seat. Consider using another vehicle to transport the child when a rear seat is not available.

The passenger sensing system is designed to turn off the front outboard passenger frontal airbag and knee airbag if:
.
The front outboard passenger seat is unoccupied.
.
The system determines an infant is present in a child restraint.
.
A front outboard passenger takes his/her weight off of the seat for a period of time.
.
There is a critical problem with the airbag system or the passenger sensing system.
When the passenger sensing system has turned off the front outboard passenger frontal airbag and knee airbag, the OFF indicator will light and stay lit as a reminder that the airbags are off. See

If the On Indicator Is Lit for a Child Restraint
The passenger sensing system is designed to turn off the front outboard passenger frontal airbag and knee airbag if the system determines that an infant is present in a child restraint. If a child restraint has been installed and the ON indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as blankets, cushions, seat covers, seat heaters, or seat massagers.

4. Reinstall the child restraint following the directions provided by the child restraint manufacturer and refer to
Securing Child Restraints (With the Seat Belt in the Rear Seat) 0 86 or Securing Child Restraints (With the Seat Belt in the Front Seat)
0 88.
Make sure the seat belt retractor is locked by pulling the shoulder belt all the way out of the retractor when installing the child restraint, even if the child restraint is equipped with a seat belt lock off. When the retractor lock is set, the belt can be tightened but not pulled out of the retractor.
5. If, after reinstalling the child restraint and restarting the vehicle, the ON indicator is still lit, turn the vehicle off. Then slightly recline the vehicle seatback and adjust the seat cushion, if adjustable, to make
sure that the vehicle seatback is not pushing the child restraint into the seat cushion.
Also make sure the child restraint is not trapped under the vehicle head restraint. If this happens, adjust the head restraint. See Head Restraints 0 39.
6. Restart the vehicle.
The passenger sensing system may or may not turn off the airbags for a child in a child restraint depending upon the child's size. It is better to secure the child restraint in a rear seat. Never put a rear-facing child restraint in the front seat, even if the ON indicator is not lit.
If the Off Indicator Is Lit for an Adult-Sized Occupant
If a person of adult size is sitting in the front outboard passenger seat, but the OFF indicator is lit, it could be because that person is not sitting properly in the seat or that the child restraint locking feature is engaged. Use the following steps to allow the system to detect that person and enable the front outboard passenger frontal airbag and knee airbag:
1. Turn the vehicle off.
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
2. Remove any additional material from the seat, such as blankets, cushions, seat covers, seat heaters, or seat massagers.
3. Place the seatback in the fully upright position.
4. Have the person sit upright in the seat, centered on the seat cushion, with legs comfortably extended.
5. If the shoulder portion of the belt is pulled out all the way, the child restraint locking feature will be engaged. This may unintentionally cause the passenger sensing system to turn the airbag off for some adult-sized occupants. If this happens, unbuckle the belt, let the belt go back all the way, and then buckle the belt again without pulling the belt out all the way.
6. Restart the vehicle and have the person remain in this position for two to three minutes after the ON indicator is lit.
{
If the front outboard passenger airbag is turned off for an adult-sized occupant, the airbag will not be able to inflate and help protect that person in a crash, resulting in an increased risk of serious injury or even death. An adult-sized occupant should not ride in the front outboard passenger seat, if the passenger airbag OFF indicator is lit.
Additional Factors Affecting System Operation
Seat belts help keep the passenger in position on the seat during vehicle maneuvers and braking, which helps the passenger sensing system maintain the passenger airbag status. See Seat Beltsand

Servicing the Airbag-Equipped Vehicle
Airbags affect how the vehicle should be serviced. There are parts of the airbag system in several places around the vehicle. Your dealer and the service manual have information about servicing the vehicle and the airbag system. To purchase a service manual, see
Publication Ordering Information
0 349.
For up to 10 seconds after the vehicle is turned off and the battery is disconnected, an airbag can still inflate during improper service. You can be injured if you are close to an airbag when it inflates. 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 qualified to do so.
Adding Equipment to the Airbag-Equipped Vehicle
Adding accessories that change the vehicle's frame, bumper system, height, front end, or side sheet metal may keep the airbag system from working properly.
The operation of the airbag system can also be affected by changing, including improperly repairing or replacing, any parts of the following:

.
Inner door seals, including speakers
Your dealer and the service manual have information about the location of the airbag modules and sensors, sensing and diagnostic module, and airbag wiring along with the proper replacement procedures.
In addition, the vehicle has a passenger sensing system for the front outboard passenger position, which includes sensors that are part of the passenger seat. The passenger sensing system may not operate properly if the original seat trim is replaced with non-GM covers, upholstery, or trim; or with
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
GM covers, upholstery, or trim designed for a different vehicle. Any object, such as an aftermarket seat heater or a comfort-enhancing pad or device, installed under or on top of the seat fabric, could also interfere with the operation of the passenger sensing system. This could either prevent proper deployment of the passenger airbag(s) or prevent the passenger sensing system from properly turning off the passenger airbag(s). See Passenger Sensing System 0 65.
If the vehicle has rollover roof-rail airbags, see Different Size Tires and Wheels 0 282 for additional important information.
If the vehicle must be modified because you have a disability and have questions about whether the modifications will affect the vehicle's airbag system, or if you have questions about whether the airbag system will be affected if the vehicle is modified for any other reason, call Customer Assistance.

72 Seats and Restraints

Child Restraints

Older Children
Older children who have outgrown booster seats should wear the vehicles seat belts.
The manufacturer instructions that come with the booster seat state the weight and height limitations for that booster. Use a booster seat with a lap-shoulder belt until the child passes the fit test below:
.
Sit all the way back on the seat. Do the knees bend at the seat edge? If yes, continue. If no, return to the booster seat.
.
Buckle the lap-shoulder belt. Does the shoulder belt rest on the shoulder? If yes, continue. If no, try using the rear seat belt comfort guide, if available. See Rear Seat Belt Comfort Guides under Lap-Shoulder Belt 0 55. If a comfort guide is not available, or if the shoulder belt still does not rest on the shoulder, then return to the booster seat.
.
Does the lap belt fit low and snug on the hips, touching the thighs? If yes, continue. If no, return to the booster seat.
.
Can proper seat belt fit be maintained for the length of the trip? If yes, continue. If no, return to the booster seat.
Q: What is the proper way to
wear seat belts?
A: An older child should wear a
lap-shoulder belt and get the additional restraint a shoulder belt can provide. The shoulder belt should not cross the face or neck. The lap belt should fit snugly below the hips, just touching the top of the thighs. This applies belt force to the child's pelvic bones in a crash. It should never be worn over the abdomen, which could cause severe or even fatal internal injuries in a crash.
Also see Rear Seat Belt Comfort Guidesunder Lap-Shoulder Belt 0 55.
According to accident statistics, children are safer when properly restrained in a rear seating position.
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
In a crash, children who are not buckled up can strike other people who are buckled up, or can be thrown out of the vehicle. Older children need to use seat belts properly.
Warning
{
Never allow more than one child to wear the same seat belt. The seat belt cannot properly spread the impact forces. In a crash, they can be crushed together and seriously injured. A seat belt must be used by only one person at a time.
Never allow a child to wear the seat belt with the shoulder belt behind their back. A child can be seriously injured by not wearing the lap-shoulder belt properly. In a crash, the child would not be restrained by the shoulder belt. The child could move too far forward increasing the chance of head and neck injury. The child might also slide under the lap belt. The belt force would then be applied right on the abdomen.

Warning
{
Children can be seriously injured or strangled if a shoulder belt is wrapped around their neck. The shoulder belt can tighten but cannot be loosened if it is locked. The shoulder belt locks when it is pulled all the way out of the retractor. It unlocks when the shoulder belt is allowed to go all the way back into the retractor, but it cannot do this if it is wrapped around a childs neck. If the shoulder belt is locked and tightened around a childs neck, the only way to loosen the belt is to cut it.

Warning (Continued)
Never leave children unattended in a vehicle and never allow children to play with the seat belts.
Every time infants and young children ride in vehicles, they should have the protection provided by appropriate child restraints. Neither the vehicle's seat belt system nor its airbag system is designed for them.
Children who are not restrained properly can strike other people, or can be thrown out of the vehicle.
Warning
{
Never hold an infant or a child while riding in a vehicle. Due to crash forces, an infant or a child will become so heavy it is not possible to hold it during a crash. For example, in a crash at only 40 km/h (25 mph), a 5.5 kg (12 lb)

or killed. Never put a rear-facing child restraint in the front outboard seat. Secure a rear-facing child restraint in a rear seat. It is also better to secure a forward-facing child restraint in a rear seat. If you must secure a forward-facing child restraint in the front outboard seat, always move the front passenger seat as far back as it will go.
Child restraints are devices used to restrain, seat, or position children in the vehicle and are sometimes called child seats or car seats.
There are three basic types of child restraints:
.
Forward-facing child restraints
.
Rear-facing child restraints
.
Belt-positioning booster seats
The proper child restraint for your child depends on their size, weight, and age, and also on whether the child restraint is compatible with the vehicle in which it will be used.
For each type of child restraint, there are many different models available. When purchasing a child restraint, be sure it is designed to be used in a motor vehicle. If it is, the child restraint will have a label saying that it meets federal motor vehicle safety standards.
The instruction manual that is provided with the child restraint states the weight and height limitations for that particular child

the risk of serious or fatal injuries during a crash, young children should always be secured in an appropriate child restraint.
Child Restraint Systems
Rear-Facing Infant Restraint
A rear-facing child restraint 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.
Forward-Facing Child Restraint
A forward-facing child restraint provides restraint for the child's body with the harness.
Booster Seats
A belt-positioning booster seat is used for children who have outgrown their forward-facing child restraint. Boosters are designed to improve the fit of the vehicle's seat belt system until the child is large enough for the vehicle seat belts to fit properly without a booster seat. See the seat belt fit test in Older Children 0 72.

Securing an Add-On Child Restraint in the Vehicle
Warning
{
A child can be seriously injured or killed in a crash if the child restraint is not properly secured in the vehicle. Secure the child restraint properly in the vehicle using the vehicle seat belt or LATCH system, following the instructions that came with that child restraint and the instructions in this manual.
To help reduce the chance of injury, the child restraint must be secured in the vehicle. Child restraints must be secured in vehicle seats by lap belts or the lap belt portion of a lap-shoulder belt, or by the LATCH system. See Lower Anchors and
Tethers for Children (LATCH System) 0 78 for more information.
Children can be endangered in a crash if the child restraint is not properly secured in the vehicle.
When securing an add-on child restraint, refer to the following:
1. Instruction labels provided on the child restraint
2. Instruction manual provided with the child restraint
3. This vehicle owner's manual
The child restraint instructions are important, so if they are not available, obtain a replacement copy from the manufacturer.
Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in the vehicle even when no child is in it.
In some areas Certified Child Passenger Safety Technicians (CPSTs) are available to inspect and demonstrate how to correctly use and install child restraints. In the U.S., refer to the National Highway Traffic Safety Administration (NHTSA) website to locate the nearest child safety seat
Seats and Restraints 77
inspection station. For CPST availability in Canada, check with Transport Canada or the Provincial Ministry of Transportation office.
Securing the Child Within the Child Restraint
Warning
{
A child can be seriously injured or killed in a crash if the child is not properly secured in the child restraint. Secure the child properly following the instructions that came with that child restraint.
Where to Put the Restraint
According to accident statistics, children and infants are safer when properly restrained in an appropriate child restraint secured in a rear seating position.
Whenever possible, children aged 12 and under should be secured in a rear seating position.
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
78 Seats and Restraints
Never put a rear-facing child restraint in the front. This is because the risk to the rear-facing child is so great if the airbag deploys.
Warning
{
A child in a rear-facing child restraint can be seriously injured or killed if the front passenger airbag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating airbag. A child in a forward-facing child restraint can be seriously injured or killed if the front passenger airbag inflates and the passenger seat is in a forward position.
Even if the passenger sensing system has turned off the front passenger frontal airbag, no system is fail-safe. No one can guarantee that an airbag will not deploy under some unusual circumstance, even though it is turned off.
(Continued)
Warning (Continued)
Secure rear-facing child restraints in a rear seat, even if the airbag is off. If you secure a forward-facing child restraint in the front seat, always move the front passenger seat as far back as it will go. It is better to secure the child restraint in a rear seat.
See Passenger Sensing System 0 65 for additional information.
When securing a child restraint with the seat belts in a rear seat position, study the instructions that came with the child restraint to make sure it is compatible with this vehicle.
Child restraints and booster seats vary considerably in size, and some may fit in certain seating positions better than others.
Depending on where you place the child restraint and the size of the child restraint, you may not be able to access adjacent seat belts or LATCH anchors for additional
passengers or child restraints. Adjacent seating positions should not be used if the child restraint prevents access to or interferes with the routing of the seat belt.
Wherever a child restraint is installed, be sure to follow the instructions that came with the child restraint and secure the child restraint properly.
Keep in mind that an unsecured child restraint can move around in a collision or sudden stop and injure people in the vehicle. Be sure to properly secure any child restraint in the vehicle even when no child is in it.
Lower Anchors and Tethers for Children (LATCH System)
The LATCH system secures a child restraint during driving or in a crash. LATCH attachments on the child restraint are used to attach the child restraint to the anchors in the
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
vehicle. The LATCH system is designed to make installation of a child restraint easier.
In order to use the LATCH system in your vehicle, you need a child restraint that has LATCH attachments. LATCH-compatible rear-facing and forward-facing child seats can be properly installed using either the LATCH anchors or the vehicles seat belts. Do not use both the seat belts and the LATCH anchorage system to secure a rear-facing or forward-facing child seat.
Booster seats use the vehicles seat belts to secure the child and the booster seat. If the manufacturer recommends that the booster seat be secured with the LATCH system, this can be done as long as the booster seat can be positioned properly and there is no interference with the proper positioning of the lap-shoulder belt on the child.
Make sure to follow the instructions that came with the child restraint, and also the instructions in this manual.
When installing a child restraint with a top tether, you must also use either the lower anchors or the seat belts to properly secure the child restraint. A child restraint must never be installed using only the top tether and anchor.
For a forward-facing 5-pt harness child restraint where the combined weight of the child and restraint are up to 29.5 kg (65 lb), use either the lower LATCH anchorages with the top tether anchorage, or the seat belt with the top tether anchorage. Where the combined weight of the child and restraint are greater than
29.5 kg (65 lb), use the seat belt with the top tether anchorage only.

Lower Anchors
Top Tether Anchor
Seats and Restraints 81
Some child restraints that have a top tether are designed for use with or without the top tether being attached. Others require the top tether always to be attached. In Canada, the law requires that forward-facing child restraints have a top tether, and that the tether be attached. Be sure to read and follow the instructions for your child restraint.
Lower Anchor and Top Tether Anchor Locations
Lower anchors (1) are metal bars built into the vehicle. There are two lower anchors for each LATCH seating position that will accommodate a child restraint with lower attachments (2).
A top tether (3, 4) is used to secure the top of the child restraint to the vehicle. A top tether anchor is built into the vehicle. The top tether attachment hook (2) on the child restraint connects to the top tether anchor in the vehicle in order to reduce the forward movement and rotation of the child restraint during driving or in a crash.
The child restraint may have a single tether (3) or a dual tether (4). Either will have a single attachment hook (2) to secure the top tether to the anchor.

H : Seating positions with two lower
anchors.
To assist in locating the lower anchors, each seating position with lower anchors has two labels, on the seatback near the crease between the seatback and the seat cushion.
The lower anchors are located under the labeled covers on the seatback near the crease between the seatback and the seat cushion.
To assist in locating the top tether anchors, the top tether anchor symbol is near the anchors.
The top tether anchors are on the back of the rear seatbacks. Remove the cargo cover before installing the top tether. The cargo cover should remain off while the top tether is in use. Be sure to use an anchor located directly behind the seating position where the child restraint will be placed.
Do not secure a child restraint in a position without a top tether anchor if a national or local law requires that the top tether be attached, or if the instructions that come with the child restraint say that the top tether must be attached.
According to accident statistics, children and infants are safer when properly restrained in a child restraint system or infant restraint system secured in a rear seating position. See Where to Put the Restraint 0 77 for additional information.

Pedestrian Protection System

Your vehicle is equipped with a pedestrian protection system which is designed to lift the rear part of the hood when a pedestrian is detected during a frontal impact within the approximate speed range.
When the vehicle is involved in a frontal impact with an object or a pedestrian, sensors in the front bumper determine the force applied by the object to the front bumper.
When the frontal impact speed is approximately between 25 km/h (15 mph) and 50 km/h (31 mph), the pedestrian protection system lifts the rear part of the hood to help reduce pedestrian head injuries. Lifting the rear part of the hood creates more clearance between the hood and the hard components in the engine compartment.
In addition, the front bumper of the vehicle was designed to help reduce the injury to a pedestrians legs.
Buick Regal Owner Manual (GMNA-Localizing-U.S./Canada-13557849) - 2020 - CRC - 6/25/19
Warning
{
After the hood has lifted, the hood hinge and latch area may be hot. Do not touch the pedestrian protection system components.
The pedestrian protection system is designed to lift the hood only once.
The pedestrian protection system may not activate under the following conditions:
.
The pedestrian impact is outside the range of the sensors located on the front bumper.
.
The sensors on the front bumper are damaged.
.
The path of the lifting hood is blocked by snow or ice. Clear any ice or snow from the hood before driving.
.
Winter fronts, grille covers, or other aftermarket equipment is attached to the bumper.
.
Vehicle speed at impact is less than 25 km/h (15 mph) or greater than 50 km/h (31 mph).
.
The vehicle impacts a small object.
For other frontal impacts or vehicle speeds, the airbags may also deploy. See Airbag System 0 59.
After the pedestrian protection system has deployed, the hood will remain in the raised position and the drivers view may be reduced by the raised hood.
Warning
{
Do not drive the vehicle when the hood is raised.
Operating the vehicle with the hood raised can obstruct your view and may cause a collision resulting in damage to the vehicle, damage to other property, personal injury, or even death.

Roof Rack System

(Wagon)
Warning
{
If something is carried on top of the vehicle that is longer or wider than the roof rack like paneling, plywood, or a mattress the wind can catch it while the vehicle is being driven. The item being carried could be violently torn off, and this could cause a collision and damage the vehicle. Never carry something longer or wider than the roof rack on top of the vehicle unless using a GM certified accessory carrier.
For vehicles with a roof rack, the rack can be used to load items. For roof racks that do not have crossrails included, GM Certified crossrails can be purchased as an accessory. See your dealer for additional information.
Loading cargo on the roof rack that weighs more than 75 kg (165 lb) or hangs over the rear or sides of the vehicle may damage the vehicle. Load cargo so that it rests evenly between the crossrails, making sure to fasten cargo securely.
To prevent damage or loss of cargo when driving, check to make sure crossrails and cargo are securely fastened. Loading cargo on the roof rack will make the vehicles center of gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden braking, or abrupt maneuvers; otherwise it may result in loss of control. If driving for a long distance, on rough roads, or at high speeds, occasionally stop the vehicle to make sure the cargo remains in its place. Do not exceed the maximum vehicle capacity when loading the vehicle.
See Vehicle Load Limits 0 171.
