Tire Pressure Monitor

This vehicle may have a Tire Pressure Monitor System (TPMS).
The TPMS warning light alerts you to a significant loss in pressure of one of the vehicle's tires. If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the Tire and Loading Information label. See Vehicle Load Limits on page 912. The warning light will remain on until the tire pressure is corrected.
During cooler conditions, the low tire pressure warning light may appear when the vehicle is first started and then turn off. This may be an early indicator that the tire pressures are getting low and the tires need to be inflated to the proper pressure.
The TPMS does not replace normal monthly tire maintenance. It is the drivers responsibility to maintain correct tire pressures.

Immobilizer Operation

This vehicle has PASS-Key®III+ (Personalized Automotive Security System) theft-deterrent system. PASS-Key III+ is a passive theft-deterrent system.
The system is automatically armed when the key is removed from the ignition.
The system is automatically disarmed when the key is turned to ON/RUN, ACC/ACCESSORY, or START from the LOCK/OFF position.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem with arming or disarming the theft-deterrent system.
When the PASS-Key III+ system senses that someone is using the wrong key, it prevents the vehicle from starting. Anyone using a trial-and-error method to start the vehicle will be discouraged because of the high number of electrical key codes.
If the engine does not start and the security light on the instrument panel cluster comes on when trying to start the vehicle, there may be a problem with the theft-deterrent system. Turn the ignition off and try again.
If the engine still does not start, and the key appears to be undamaged, try another ignition key. At this time, you may also want to check the fuse. See Fuses and Circuit Breakers on page 1034.
If the engine still does not start with the other key, the vehicle needs service. If the vehicle does start, the first key may be faulty. See your dealer who can service the PASS-Key III+ to have a new key made.
It is possible for the PASS-Key III+ decoder to learn the transponder value of a new or replacement key. Up to 10 keys may be programmed for the vehicle. The following procedure is for programming additional keys only. If all the currently programmed keys are lost or do not operate, you must see your dealer or a locksmith who can service PASS-Key III+ to have keys made and programmed to the system.
See your dealer or a locksmith who can service PASS-Key III+ to get a new key blank cut exactly as the ignition key that operates the system.

Windows

WARNING
{
Leaving children, helpless adults, or pets in a vehicle with the windows closed is dangerous. They can be overcome by the extreme heat and suffer permanent injuries or even death from heat stroke. Never leave a child, a helpless adult, or a pet alone in a vehicle, especially with the windows closed in warm or hot weather.
The vehicle aerodynamics are designed to improve fuel economy performance. This may result in a pulsing sound when either rear window is down and the front windows are up. To reduce the sound, open either a front window or the sunroof (if equipped).

Head Restraints

The vehicle's front seats have adjustable head restraints in the outboard seating positions.
WARNING
{
With head restraints that are not installed and adjusted properly, there is a greater chance that occupants will suffer a neck/ spinal injury in a crash. Do not drive until the head restraints for all occupants are installed and adjusted properly.
Adjust the head restraint so that the top of the restraint is at the same height as the top of the occupant's head. This position reduces the chance of a neck injury in a crash.
The height of the head restraint can be adjusted. Pull the head restraint up to raise it. Try to move the head restraint to make sure that it is locked in place.
To lower the head restraint, press the button located on top of the seatback, and push the head restraint down. Try to move the head restraint after the button is released to make sure that it is locked in place.
The front seat outboard head restraints are not designed to be removed.

Reclining Seatbacks

WARNING
{
Sitting in a reclined position when the vehicle is in motion can be dangerous. Even when buckled up, the safety belts cannot do their job when reclined like this.
The shoulder belt cannot do its job because it 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.
(Continued)
WARNING (Continued)
The lap belt cannot do its job either. In a crash, the 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 safety belt properly.
Do not have a seatback reclined if the vehicle is moving.

Safety Belts

This section of the manual describes how to use safety belts properly. It also describes some things not to do with safety belts.
WARNING
{
Do not let anyone ride where a safety belt cannot be worn properly. In a crash, if you or your passenger(s) are not wearing safety belts, the injuries can be much worse. You can hit things inside the vehicle harder or be ejected from the vehicle. You and your passenger(s) can be seriously injured or killed. In the same crash, you might not be, if you are buckled up. Always fasten your safety belt, and check that your passenger(s) are restrained properly too.
WARNING
{
It is extremely dangerous to ride in a cargo area, inside or outside of a vehicle. In a collision, people riding in these areas are more likely to be seriously injured or killed. Do not allow people to ride in any area of your vehicle that is not equipped with seats and safety belts. Be sure everyone in your vehicle is in a seat and using a safety belt properly.
This vehicle has indicators as a reminder to buckle the safety belts. See Safety Belt Reminders on page 514 for additional information.
In most states and in all Canadian provinces, the law requires wearing safety belts. Here is why:
You never know if you will be in a crash. If you do have a crash, you do not know if it will be a serious one.
A few crashes are mild, and some crashes can be so serious that even buckled up, a person would not survive. But most crashes are in between. In many of them, people who buckle up can survive and sometimes walk away. Without safety belts they could have been badly hurt or killed.
After more than 40 years of safety belts in vehicles, the facts are clear. In most crashes buckling up does matter ... a lot!

Why Safety Belts Work
When you ride in or on anything, you go as fast as it goes.
Seats and Restraints 3-11
Take the simplest vehicle. Suppose it is just a seat on wheels.
Put someone on it. Get it up to speed. Then stop the
vehicle. The rider does not stop.
Black plate (12,1)
Chevrolet Impala Owner Manual - 2011
3-12 Seats and Restraints
The person keeps going until stopped by something. In a real vehicle, it could be the windshield...
or the instrument panel...
With safety belts, you slow down as the vehicle does. You get more time to stop. You stop over more distance, and your strongest bones take the forces. That is why safety belts make such good sense.
Questions and Answers About Safety Belts
Q: Will I be trapped in the vehicle
after a crash if I am wearing a safety belt?
A: You could be whether you are
wearing a safety belt or not. But your chance of being conscious during and after an accident, so you can unbuckle and get out, is much greater if you are belted. And you can unbuckle a safety belt, even if you are upside down.
or the safety belts!
Black plate (13,1)
Chevrolet Impala Owner Manual - 2011
Seats and Restraints 3-13
Q: If my vehicle has airbags,
why should I have to wear safety belts?
A: Airbags are supplemental
systems only; so they work with safety belts not instead of them. Whether or not an airbag is provided, all occupants still have to buckle up to get the most protection. That is true not only in frontal collisions, but especially in side and other collisions.
Q: If I am a good driver, and
I never drive far from home, why should I wear safety belts?
A: You may be an excellent driver,
but if you are in a crash even one that is not your fault you and your passenger(s) can be hurt. Being a good driver does not protect you from things beyond your control, such as bad drivers.
Most accidents occur within 40 km (25 miles) of home. And the greatest number of serious injuries and deaths occur at speeds of less than 65 km/h (40 mph).
Safety belts are for everyone.

How to Wear Safety Belts Properly

This section is only for people of adult size.
Be aware that there are special things to know about safety belts and children. And there are different rules for smaller children and infants. If a child will be riding in the vehicle, see Older Children on
page 341 or Infants and Young Children on page 343. Follow those
rules for everyone's protection.
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 safety belts.
Occupants who are not buckled up can be thrown out of the vehicle in a crash. And they can strike others in the vehicle who are wearing safety belts.

3-14 Seats and Restraints
First, before you or your passenger(s) wear a safety belt, there is important information you should know.
Sit up straight and always keep your feet on the floor in front of you. The lap part of the belt should be worn 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. The shoulder belt should go 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.
Q: What is wrong with this?
A: The shoulder belt is too loose.
It will not give as much protection this way.

WARNING
{
You can be seriously hurt if your shoulder belt is too loose. In a crash, you would move forward too much, which could increase injury. The shoulder belt should fit snugly against your body.
Q: What is wrong with this?
A: The lap belt is too loose.
It will not give nearly as much protection this way.

WARNING
{
You can be seriously injured if your belt is buckled in the wrong place like this. In a crash, the belt would go up over your abdomen. The belt forces would be there, not on the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you.
Q: What is wrong with this?
A: The belt is over an armrest.
Black plate (17,1)
Chevrolet Impala Owner Manual - 2011

WARNING
{
You can be seriously injured if your belt goes over an armrest like this. The belt would be much too high. In a crash, you can slide under the belt. The belt force would then be applied on the abdomen, not on the pelvic bones, and that could cause serious or fatal injuries. Be sure the belt goes under the armrests.
Q: What is wrong with this?
A: The shoulder belt is worn under
the arm. It should be worn over the shoulder at all times.
WARNING
{
You can be seriously injured if you wear the shoulder belt under your arm. In a crash, your body would move too far forward, which would increase the chance of head and neck injury. Also, the belt would apply too much force to the ribs, which are not as strong as shoulder bones. You could also severely injure internal organs like your liver or spleen. The shoulder belt should go over the shoulder and across the chest.

Q: What is wrong with this?
A: The belt is behind the body.
WARNING
{
You can be seriously injured by not wearing the lap-shoulder belt properly. In a crash, you would not be restrained by the shoulder belt. Your body could move too far forward increasing the chance of head and neck injury. You might also slide under the lap belt. The belt force would then be applied right on the abdomen. That could cause serious or fatal injuries. The shoulder belt should go over the shoulder and across the chest.
Q: What is wrong with this?
A: The belt is twisted across
the body.
WARNING
{
You can be seriously injured by a twisted belt. In a crash, you would not have the full width of the belt to spread impact forces. If a belt is twisted, make it straight so it can work properly, or ask your dealer to fix it.

Lap-Shoulder Belt

All seating positions in the vehicle have a lap-shoulder belt except for the center front passenger position (if equipped), which has a lap belt. See Lap Belt on page 324 for more information.
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.
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. If this happens, let the belt go back all the way and start again.
Engaging the child restraint locking feature in the right front seating position may affect the passenger sensing system. See
Passenger Sensing System on page 334.
3. Push the latch plate into the buckle until it clicks.
If the latch plate will not go fully into the buckle, check if the correct buckle is being used.
Pull up on the latch plate to make sure it is secure. If the belt is not long enough, see Safety Belt Extender on page 324.
Position the release button on the buckle so that the safety belt could be quickly unbuckled if necessary.
4. If equipped with a shoulder belt height adjuster, move it to the height that is right for you. See Shoulder Belt Height Adjuster in this section for instructions on use and important safety information.
Black plate (20,1)
Chevrolet Impala Owner Manual - 2011
3-20 Seats and Restraints
5. To make the lap part tight, pull up on the shoulder belt.
It may be necessary to pull stitching on the safety belt through the latch plate to fully tighten the lap belt on smaller occupants.
To unlatch the belt, push the button on the buckle. The belt should return to its stowed position.
Before a door is closed, be sure the belt is out of the way. If a door is slammed against a safety belt, damage can occur to both the safety belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has shoulder belt height adjusters for the driver and right front passenger positions.
Adjust the height so the shoulder portion of the belt is on the shoulder and not falling off of it. The belt should be close to, but not contacting, the neck. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. See How
to Wear Safety Belts Properly on page 313.
Black plate (21,1)
Chevrolet Impala Owner Manual - 2011
Seats and Restraints 3-21
Squeeze the buttons (A) on the sides of the height adjuster and move the height adjuster to the desired position.
You can move the adjuster up just by pushing up on the shoulder belt guide.
After the adjuster is set to the desired position, try to move it down without squeezing the buttons to make sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt pretensioners for front outboard occupants. Although the safety belt pretensioners cannot be seen, they are part of the safety belt assembly. They can help tighten the safety belts during the early stages of a moderate to severe frontal and near frontal crash if the threshold conditions for pretensioner
activation are met. And, if the vehicle has side impact airbags, safety belt pretensioners can help tighten the safety belts in a side crash.
Pretensioners work only once. If the pretensioners activate in a crash, they will need to be replaced, and probably other new parts for the vehicle's safety belt system. See
Replacing Safety Belt System Parts After a Crash on page 325.

Rear Safety Belt Comfort Guides
This vehicle may have rear shoulder belt comfort guides for each outboard passenger position in the rear seat. If not, they are available through your dealer. The guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed and properly adjusted, the comfort guide positions the belt away from the neck and head.
Here is how to install a comfort guide to the safety belt:
1. Pull the guide out from the pocket on the edge of the seatback.
2. Place the guide over the belt, and insert the two edges of the belt into the slots of the guide.
3. Be sure that the belt is not twisted and it lies flat. The elastic cord must be under the belt and the guide on top.
WARNING
{
A safety belt that is not properly worn may not provide the protection needed in a crash.
(Continued)
Black plate (23,1)

Seats and Restraints 3-23
WARNING (Continued)
The person wearing the belt could be seriously injured. The shoulder belt should go over the shoulder and across the chest. These parts of the body are best able to take belt restraining forces.
4. Buckle, position, and release the safety belt as described previously in this section. Make sure the shoulder portion of the
belt is on the shoulder and not falling off of it. The belt should be close to, but not contacting, the neck.
To remove and store the comfort guide, squeeze the belt edges together so that the safety belt can be removed from the guide. Slide the guide into the storage pocket on the edge of the seatback.

Safety Belt Use During Pregnancy

Safety belts work for everyone, including pregnant women. Like all occupants, they are more likely to be seriously injured if they do not wear safety belts.
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 safety 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 safety belts effective is wearing them properly.

Lap Belt

This section is only for the lap belt. To learn how to wear a lap-shoulder belt, see Lap-Shoulder Belt on page 319.
The vehicle may have a center seating position. When you sit in the center front seating position, you have a lap safety belt, which has no retractor.
To make the belt longer, tilt the latch plate and pull it along the belt.
Buckle, position, and release it the same way as the lap part of a lap-shoulder belt.
To make the belt shorter, pull its free end as shown until the belt is snug.
If the belt is not long enough, see Safety Belt Extender on page 324.
Make sure the release button on the buckle is positioned so you would be able to unbuckle the safety belt quickly if necessary.

Safety Belt Extender

If the vehicle's safety belt will fasten around you, you should use it.
But if a safety 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 seats. To wear it, attach it to the regular safety belt. For more information, see the instruction sheet that comes with the extender.

Safety System Check

Now and then, check that the safety belt reminder light, safety belts, buckles, latch plates, retractors, and anchorages are working properly. Look for any other loose or damaged safety belt system parts that might keep a safety belt system

from doing its job. See your dealer to have it repaired. Torn or frayed safety belts may not protect you in a crash. They can rip apart under impact forces. If a belt is torn or frayed, get a new one right away.
Make sure the safety belt reminder light is working. See Safety Belt Reminders on page 514 for more information.
Keep safety belts clean and dry. See Safety Belt Care on page 325.

Safety Belt Care

Keep belts clean and dry.
WARNING
{
Do not bleach or dye safety belts. It may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water.

Replacing Safety Belt System Parts After a Crash

WARNING
{
A crash can damage the safety belt system in the vehicle. A damaged safety 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 safety 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 safety belts may not be necessary. But the safety belt assemblies that were used during any crash may have been stressed or damaged. See your dealer to have the safety belt assemblies inspected or replaced.
New parts and repairs may be necessary even if the safety belt system was not being used at the time of the crash.
Have the safety 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 on page 515.

Airbag System

The vehicle has the following airbags:
.
A frontal airbag for the driver.
.
A frontal airbag for the right front passenger.
.
A seatmounted side impact airbag for the driver.
.
A seatmounted side impact airbag for the right front passenger.
.
A roof-rail airbag for the driver and passenger directly behind the driver.
.
A roof-rail airbag for the right front passenger and passenger seated directly behind the right front passenger.
All of the airbags in the vehicle will have the word AIRBAG embossed in the trim or on an attached label near the deployment opening.
For frontal airbags, the word AIRBAG will appear on the middle part of the steering wheel for the driver and on the instrument panel for the right front passenger.
With seatmounted side impact airbags, the word AIRBAG will appear on the side of the seatback closest to the door.
With roof-rail airbags, the word AIRBAG will appear along the headliner or trim.
Airbags are designed to supplement the protection provided by safety 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 safety belt even if you have airbags. Airbags are designed to work with safety belts, but do not replace them. Also, airbags are not designed to deploy in every crash. In some crashes safety belts are your only restraint. See When Should an Airbag Inflate? on page 330.
Wearing your safety belt during a crash helps reduce your chance of hitting things inside the vehicle or being ejected from it. Airbags are supplemental restraintsto the safety belts. Everyone in your vehicle should wear a safety belt properly whether or not there is an airbag for that person.
Black plate (27,1)
Chevrolet Impala Owner Manual - 2011
Seats and Restraints 3-27
WARNING
{
Airbags inflate with great force, 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 the airbag, as you would be if you were sitting on the edge of your seat or leaning forward. Safety belts help keep you in position before and during a crash. Always wear your safety belt, even with airbags. The driver should sit as far back as possible while still maintaining control of the vehicle.
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. Airbags plus lap-shoulder belts offer protection for adults and older children, but not for young children and infants. Neither the vehicle's safety belt system nor its airbag system is designed for them. Young children and infants need the protection that a child restraint system can provide. Always secure children properly in your vehicle. To read how, see Older
Children on page 341 or Infants and Young Children on page 343.
There is an airbag readiness light on the instrument panel 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 on page 515 for more information.

When Should an Airbag Inflate?

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 right front passenger's head and chest. However, they are only designed to inflate if the impact exceeds a predetermined 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.
Whether the 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.
Frontal airbags may inflate at different crash speeds. For example:
.
If the vehicle hits a stationary object, the airbags could inflate at a different crash speed than if the vehicle hits a moving object.
.
If the vehicle hits an object that deforms, the airbags could inflate at a different crash speed than if the vehicle hits an object that does not deform.
.
If the vehicle hits a narrow object (like a pole), the airbags could inflate at a different crash speed than if the vehicle hits a wide object (like a wall).
.
If the vehicle goes into an object at an angle, the airbags could inflate at a different crash speed than if the vehicle goes straight into the object.
Thresholds can also vary with specific vehicle design.
Frontal airbags are not intended to inflate during vehicle rollovers, rear impacts, or in many side impacts.
In addition, the vehicle has dual-stage frontal airbags. Dual-stage airbags adjust the restraint according to crash severity. The 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, dual-stage airbags inflate at a level less than full deployment. For more severe frontal impacts, full deployment occurs.
The vehicle has seat-mounted side impact and roof-rail airbags. See Airbag System on page 326. Seat-mounted side impact and roof-rail airbags are intended to inflate in moderate to severe side crashes. Seat-mounted side impact and roof-rail airbags will inflate if the crash severity is above the system's designed threshold level. The threshold level can vary with specific vehicle design.
Black plate (31,1)
Chevrolet Impala Owner Manual - 2011
Seats and Restraints 3-31
Roof-rail airbags are not intended to inflate in rollovers or rear impacts. A seat-mounted side impact airbag is intended to deploy on the side of the vehicle that is struck. Both roof-rail airbags will deploy when either side of the vehicle is struck.
In any particular crash, no one can say whether an airbag should have inflated simply because of the damage to a vehicle or because of what the repair costs were. For frontal airbags, inflation is determined by what the vehicle hits, the angle of the impact, and how quickly the vehicle slows down. For seat-mounted side impact and roof-rail airbags, deployment is determined by the location and severity of the side impact.

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
airbag causing the bag to break out of the cover and deploy. The inflator, the airbag, and related hardware are all part of the airbag module.
Frontal airbag modules are located inside the steering wheel and instrument panel. For vehicles with seatmounted side impact airbags, there are airbags modules in the side of the front seatbacks closest to the door. For vehicles with roof-rail airbags, there are airbag modules in the ceiling of the vehicle, near the side windows that have occupant seating positions.

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 safety belts. Frontal airbags distribute the force of the impact more evenly over the occupant's upper body, stopping the occupant more gradually. Seat-mounted side impact and roof-rail airbags distribute the force of the impact more evenly over the occupant's upper body.
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? on page 330 for more information.
Airbags should never be regarded as anything more than a supplement to safety belts.

What Will You See After an Airbag Inflates?

After the frontal airbags and seat-mounted side impact airbags inflate, they quickly deflate, so quickly that some people may not even realize an airbag inflated. Roof-rail airbags may still be at least partially inflated for some time after they deploy. Some components of the airbag module may be hot for several minutes. For location of the airbag modules, see What Makes an Airbag Inflate? on page 331.
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.
(Continued)
WARNING (Continued)
If you experience breathing problems following an airbag deployment, you should seek medical attention.
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. You can lock the doors, turn off the interior lamps and hazard warning flashers by using the controls for those features.
Black plate (33,1)
Chevrolet Impala Owner Manual - 2011
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 right front 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 your vehicle covers the need to replace other parts.

Passenger Sensing System

The vehicle has a passenger sensing system for the right front passenger position. The passenger airbag status indicator will be visible on the instrument panel when the vehicle is started.
United States
Canada
The words ON and OFF, or the symbol for on and off, will be visible during the system check. If you are using remote start to start the
vehicle from a distance, if equipped, you may not see the system check. When the system check is complete, either the word ON or the word OFF, or the symbol for on or off, will be visible. See Passenger
Airbag Status Indicator on page 516.
The passenger sensing system will turn off the right front passenger frontal airbag under certain conditions. The driver airbag, seatmounted side impact airbags, and roofrail airbags are not affected by the passenger sensing system.
The passenger sensing system works with sensors that are part of the right front passenger seat. The sensors are designed to detect the presence of a properly-seated occupant and determine if the right front passenger frontal airbag should be enabled (may inflate) or not.
According to accident statistics, children are safer when properly secured in a rear seat in the correct child restraint for their weight and size.
We recommend that children be secured in a rear seat, including: an infant or a child riding in a rear-facing child restraint; a child riding in a forward-facing child seat; an older child riding in a booster seat; and children, who are large enough, using safety belts.
A label on the sun visor says, 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 deploys.
Black plate (35,1)
Chevrolet Impala Owner Manual - 2011
WARNING
{
A child in a rear-facing child restraint can be seriously injured or killed if the right 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 right front passenger airbag inflates and the passenger seat is in a forward position.
Even if the passenger sensing system has turned off the right 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 the airbag 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 right 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.
The passenger sensing system is designed to turn off the right front passenger frontal airbag if:
.
The right front passenger seat is unoccupied.
.
The system determines that an infant is present in a child restraint.
Seats and Restraints 3-35
.
A right front passenger takes his/her weight off of the seat for a period of time.
.
Or, if there is a critical problem with the airbag system or the passenger sensing system.
When the passenger sensing system has turned off the right front passenger frontal airbag, the off indicator will light and stay lit to remind you that the airbag is off. See Passenger Airbag Status Indicator on page 516.
The passenger sensing system is designed to turn on (may inflate) the right front passenger frontal airbag anytime the system senses that a person of adult size is sitting properly in the right front passenger seat. When the passenger sensing system has allowed the airbag to be enabled, the on indicator will light and stay lit to remind you that the airbag is active.
Black plate (36,1)
Chevrolet Impala Owner Manual - 2011
3-36 Seats and Restraints
For some children, including children in child restraints, and for very small adults, the passenger sensing system may or may not turn off the right front passenger frontal airbag, depending upon the person's seating posture and body build. Everyone in the vehicle who has outgrown child restraints should wear a safety belt properly whether or not there is an airbag for that person.
WARNING
{
If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light on page 515 for more information, including important safety information.
If the On Indicator is Lit for 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 (Rear Seat Position) on page 355 or Securing Child Restraints (Center Front Seat Position) on page 357 or Securing Child Restraints (Right Front Seat Position) on page 358.
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 on page 32.
6. Restart the vehicle.
The passenger sensing system may or may not turn off the airbag for a child in a child restraint depending upon the child's seating posture and body build. It is better to secure the child restraint in a rear seat.

Chevrolet Impala Owner Manual - 2011
Seats and Restraints 3-37
If the Off Indicator is Lit for an Adult-Size Occupant
If a person of adult-size is sitting in the right front passenger seat, but the off indicator is lit, it could be because that person is not sitting properly in the seat. If this happens,
use the following steps to allow the system to detect that person and enable the right front passenger frontal airbag:
1. Turn the vehicle off.
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. Restart the vehicle and have the person remain in this position for two to three minutes after the on indicator is lit.
Additional Factors Affecting System Operation
Safety 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 Safety Beltsand Child Restraints in the Index for additional information about the importance of proper restraint use.
A thick layer of additional material, such as a blanket or cushion, or aftermarket equipment such as seat covers, seat heaters, and seat massagers can affect how well the passenger sensing system operates. We recommend that you not use seat covers or other aftermarket equipment except when approved by GM for your specific vehicle. See Adding Equipment to
the Airbag-Equipped Vehicle on page 339 for more information
about modifications that can affect how the system operates.
Black plate (38,1)
Chevrolet Impala Owner Manual - 2011
3-38 Seats and Restraints
A wet seat can affect the performance of the passenger sensing system. Here is how:
.
The passenger sensing system may turn off the passenger airbag when liquid is soaked into the seat. If this happens, the off indicator will be lit, and the airbag readiness light on the instrument panel will also be lit.
.
Liquid pooled on the seat that has not soaked in may make it more likely that the passenger sensing system will enable (turn on) the passenger airbag while a child restraint or child occupant is on the seat. If the passenger airbag is turned on, the on indicator will be lit.
If the passenger seat gets wet, dry the seat immediately. If the airbag readiness light is lit, do not install a child restraint or allow anyone to occupy the seat. See Airbag Readiness Light on page 515 for important safety information.
The on indicator may be lit if an object, such as a briefcase, handbag, grocery bag, laptop or other electronic device, is put on an unoccupied seat. If this is not desired, remove the object from the seat.
WARNING
{
Stowing of articles under the passenger seat or between the passenger seat cushion and seatback may interfere with the proper operation of the passenger sensing system.

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
Service Publications Ordering Information on page 1313.
WARNING
{
For up to 10 seconds after the ignition 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

Q: Is there anything I might add
to or change about the vehicle that could keep the airbags from working properly?
A: Yes. If you add things that
change the vehicle's frame, bumper system, height, front end or side sheet metal, they may keep the airbag system from working properly. Changing or moving any parts of the front seats, safety belts, the airbag sensing and diagnostic module, steering wheel, instrument panel, roof-rail airbag modules, ceiling headliner or pillar garnish trim, front sensors, side impact sensors, or airbag wiring can affect the operation of the airbag system.
In addition, the vehicle has a passenger sensing system for the right front passenger
position, which includes sensors that are part of the passenger's 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 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 on page 334.

Child Restraints

Older Children

Older children who have outgrown booster seats should wear the vehicle's safety belts.
The manufacturer's 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 safety belt comfort guide. See Rear Safety Belt Comfort Guides under Lap-Shoulder Belt on page 319 for more information. If the shoulder belt still does not rest on the shoulder, then return to the booster seat.
Seats and Restraints 3-41
.
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 safety 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 safety 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 Safety Belt Comfort Guidesunder Lap-Shoulder Belt on page 319.

3-42 Seats and Restraints
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.
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 safety belts properly.
WARNING
{
Never do this.
Never allow two children to wear the same safety belt. The safety belt can not properly spread the impact forces. In a crash, the two children can be crushed together and seriously injured. A safety belt must be used by only one person at a time.
WARNING
{
Never do this.
Never allow a child to wear the safety 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 (Continued)
That could cause serious or fatal injuries. The shoulder belt should go over the shoulder and across the chest.

Infants and Young Children

Everyone in a vehicle needs protection! This includes infants and all other children. Neither the distance traveled nor the age and size of the traveler changes the need, for everyone, to use safety restraints. In fact, the law in every state in the United States and in every Canadian province says children up to some age must be restrained while in a vehicle.
WARNING
{
Children can be seriously injured or strangled if a shoulder belt is wrapped around their neck and the safety belt continues to tighten. Never leave children unattended in a vehicle and never allow children to play with the safety belts.
Airbags plus lapshoulder belts offer protection for adults and older children, but not for young children and infants. Neither the vehicle's safety belt system nor its airbag system is designed for them. Every time infants and young children ride in vehicles, they should have the protection provided by appropriate child restraints.

3-44 Seats and Restraints
Children who are not restrained properly can strike other people, or can be thrown out of the vehicle.
WARNING
{
Never do this.
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) infant will suddenly become a 110 kg (240 lb) force on a person's arms. An infant should be secured in an appropriate restraint.
WARNING
{
Never do this.
Children who are up against, or very close to, any airbag when it inflates can be seriously injured or killed. Never put a rear-facing child restraint in the right front 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.
(Continued)
WARNING (Continued)
If you must secure a forward-facing child restraint in the right front seat, always move the front passenger seat as far back as it will go.

Q: What are the different types of
add-on child restraints?
A: Add-on child restraints, which
are purchased by the vehicle's owner, are available in four basic types. Selection of a particular restraint should take into consideration not only the child's weight, height, and age but also whether or not the restraint will be compatible with the motor vehicle in which it will be used.
For most basic types of child restraints, 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 restraint will have a label saying that it meets federal motor vehicle safety standards.
The restraint manufacturer's instructions that come with the restraint state the weight and height limitations for a particular child restraint. In addition, there are many kinds of restraints available for children with special needs.
WARNING
{
To reduce the risk of neck and head injury during a crash, infants need complete support. This is because an infant's neck is not fully developed and its head weighs so much compared with the rest of its body. In a crash, an infant in a rear-facing child restraint settles into the restraint, so the crash forces can be distributed across the strongest part of an infant's body, the back and shoulders. Infants should always be secured in rear-facing child restraints.
WARNING
{
A young child's hip bones are still so small that the vehicle's regular safety belt may not remain low on the hip bones, as it should. Instead, it may settle up around the child's abdomen. In a crash, the belt would apply force on a body area that is unprotected by any bony structure. This alone could cause serious or fatal injuries. To reduce the risk of serious or fatal injuries during a crash, young children should always be secured in appropriate child restraints.

Child Restraint Systems

(A) RearFacing Infant Seat
A rear-facing infant seat (A) 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.
(B) Forward-Facing Child Seat
A forward-facing child seat (B) provides restraint for the child's body with the harness.
(C) Booster Seats
A booster seat (C) is a child restraint designed to improve the fit of the vehicle's safety belt system. A booster seat can also help a child to see out the window.

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's safety 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 restraint systems 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) on page 350 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 instructions that come with the restraint which may be on the restraint itself or in a booklet, or both, and to this 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 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 a child restraint system or infant restraint system secured in a rear seating position.
We recommend that children and child restraints be secured in a rear seat, including: an infant or a child riding in a rear-facing child restraint; a child riding in a forward-facing child seat; an older child riding in a booster seat; and children, who are large enough, using safety belts.
A label on your sun visor says, 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 deploys.
WARNING
{
A child in a rear-facing child restraint can be seriously injured or killed if the right 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 right front passenger airbag inflates and the passenger seat is in a forward position.
(Continued)
WARNING (Continued)
The vehicle may have a passenger sensing system which is designed to turn off the right front passenger frontal airbag under certain conditions.
Even if the passenger sensing system, if equipped, has turned off the right 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.

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 right 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 on page 334 for additional information.
WARNING
{
A child in a child restraint in the center front seat can be badly injured or killed by the frontal airbags if they inflate. Never secure a child restraint in the center front seat. It is always better to secure a child restraint in a rear seat.
Do not use child restraints in the center front seat position.
When securing a child restraint in a rear seating position, study the instructions that came with your 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. Always make sure the child restraint is properly secured.
Depending on where you place the child restraint and the size of the child restraint, you may not be able to access adjacent safety belt assemblies 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 safety belt.
Wherever a child restraint is installed, be sure to 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 your vehicle even when no child is in it.

Lower Anchors and Tethers for Children (LATCH System)

The LATCH system holds a child restraint during driving or in a crash. This system is designed to make installation of a child restraint easier. The LATCH system uses anchors in the vehicle and attachments on the child restraint that are made for use with the LATCH system.
Make sure that a LATCH-compatible child restraint is properly installed using the anchors, or use the vehicle's safety belts to secure the restraint, following the instructions that came with that 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 safety belts to properly secure the child restraint. A child restraint must never be installed using only the top tether and anchor.
In order to use the LATCH system in your vehicle, you need a child restraint that has LATCH attachments. The child restraint manufacturer will provide you with instructions on how to use the child restraint and its attachments. The following explains how to attach a child restraint with these attachments in your vehicle.
Not all vehicle seating positions or child restraints have lower anchors and attachments or top tether anchors and attachments.

Lower Anchors
Lower anchors (A) 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 (B).
Top Tether Anchor
A top tether (A, C) anchors the top of the child restraint to the vehicle. A top tether anchor is built into the vehicle. The top tether attachment (B) 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.
Your child restraint may have a single tether (A) or a dual tether (C). Either will have a single attachment (B) to secure the top tether to the anchor.
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
Rear Seat
i (Top Tether Anchor): Seating
positions with top tether anchors.
j (Lower Anchor): Seating
positions with two lower anchors.
To assist you in locating the lower anchors, each seating position with lower anchors has two labels, near the crease between the seatback and the seat cushion.
To assist you in locating the top tether anchors, the top tether anchor symbol is located on the cover.
The top tether anchors are located under the covers on the rear seatback filler panel behind each head restraint. Be sure to use an anchor located on the same side of the vehicle as 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.
