to remind you and your passengers to buckle your safety belts. See Safety Belt Reminder Light on page 3-33 and Passenger Safety Belt Reminder Light on page 3-34.

Why Safety Belts Work When you ride in or on anything, you go as fast as it goes. Put someone on it. Take the simplest vehicle. Suppose it is just a seat on wheels. 1-10 - 2006 Buick LaCrosse | Owner's Manual - Page 17
Get it up to speed. Then stop the vehicle. The rider does not stop. The person keeps going until stopped by something. In a real vehicle, it could be the windshield... 1-11 - 2006 Buick LaCrosse | Owner's Manual - Page 18
or the instrument panel... or the safety belts! 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. 1-12 - 2006 Buick LaCrosse | Owner's Manual - Page 19
much greater if you are belted. Q: If my vehicle has airbags, why should I have to wear safety belts? A: Airbags are in many vehicles today and will be in most of them in the future. But they are supplemental systems only; so they work with safety belts - not instead of them. Every airbag system - 2006 Buick LaCrosse | Owner's Manual - Page 20
Wear Safety Belts Properly This part is only for people of adult size. Be aware that there are special things to know about safety belts and which restraint systems your vehicle has. We will start with the driver position. Driver Position Lap-Shoulder Belt The driver has a lap-shoulder belt. Here - 2006 Buick LaCrosse | Owner's Manual - Page 21
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 safety belt locks if there is a sudden stop or crash, or if you pull the belt very quickly out of the retractor. 1-15 - 2006 Buick LaCrosse | Owner's Manual - Page 22
with this? {CAUTION: 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 against your body. A: The shoulder belt is too loose. It will not give nearly as much protection this way. 1-16 - 2006 Buick LaCrosse | Owner's Manual - Page 23
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 at the pelvic bones. This could cause serious internal injuries. Always buckle your belt into the buckle nearest you. A: The belt is buckled in the wrong place. 1-17 - 2006 Buick LaCrosse | Owner's Manual - Page 24
this? {CAUTION: 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 - 2006 Buick LaCrosse | Owner's Manual - Page 25
wrong with this? {CAUTION: 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. A: The belt is twisted across the body. 1-19 - 2006 Buick LaCrosse | Owner's Manual - Page 26

add-on child restraints? A: Add standards. The restraint manufacturer's instructions that come with the restraint, 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 - 2006 Buick LaCrosse | Owner's Manual - Page 39
including support for the head and neck. This is necessary because a newborn infant's neck is weak and its head weighs so much compared with the rest of its body.
