The safety belt warning light ª comes on for 6 seconds when the ignition is switched on. A warning chime also sounds for up to 6 seconds if the driver's safety belt is not buckled. The chime stops soon-er if the driver buckles his or her safety belt. The warning light and the chime go out when both driver and front passenger have bucked their safety belts.
If the driver and front seat passenger do not both fasten their safety belts within about 24 seconds after the chime stops and the vehicle is moving at a speed of more than about 15 mph (25 km/h), the chime will again sound for about 6 seconds, then go off for about 24 seconds, then sound again for about another 6 seconds. The same thing happens if one of the safety belts is fastened and then unfastened while the vehicle is moving. The safety belt warning light ª also flashes. The warning chime continues to sound at 24 second intervals for up to 2 minutes. No chime sounds at speeds of less than about 5 mph (8 km/h).
If the ignition is switched on, the safety belt warning light ª stays on until the driver and front passen-ger have both buckled their safety belts.
WARNING
Not wearing a safety belt or wearing an improperly positioned safety belt increases the risk of severe personal injury or death. Safety belts offer optimum protection only when used cor-rectly.
Frontal collisions and laws of physics

The physical principles of a frontal collision are simple. Both the moving vehicle and the passenger
possess energy ⇒ fig. 44, which varies with vehicle speed and body weight. Engineers call this energy “kinetic energy.”
The higher the speed of the vehicle and the greater the vehicle's weight, the more energy has to be “absorbed” in a crash.
Vehicle speed is the most significant factor. If your speed doubles (for example, from 15 mph to 30 mph – 25 km/h to 50 km/h), the energy increases 4 times!
Because the occupants of the vehicle in the above example are not using safety belts, they are not “attached” to the vehicle. In a frontal collision, they will keep moving at the same speed the vehicle was moving just before the crash, until something stops them - here, the inside of the passenger compartment. Because the occupants of the vehicle in the example are not wearing safety belts, their
entire kinetic energy will be absorbed by impact with the wall ⇒ fig. 45.
The same principles apply to people in a vehicle that is in a frontal collision on the highway. Even at city speeds of 20–30 mph (30–50 km/h), the forces acting on the body can reach one ton (2,000 lbs or 1,000 kg) or more. At greater speeds, these forces are even higher.
Of course, the laws of physics don't apply just to frontal collisions; they determine what happens in all kinds of accidents and collisions.
