If the air bag lamp comes on, then your car’s computer sees a problem with the air bag system. This safety concern should be addressed promptly.
The creation and evolution of air bags have saved countless lives. Older models were single stage; they would deploy violently and could cause damage to the occupant. Current airbags have multi-stages; they have a small burst of deployment before a full engagement to lessen the force.
This happens in milliseconds. Although the deployment is very loud, you will not likely hear it in an accident.
In days past you would never hear of such things as replacing your brake fluid. Now, with the introduction of anti lock brakes it has to be done. Failure to do so can cause faults within the ABS, Traction, and Stability Control systems of your vehicle.
Brake fluid is hydroscopic. That means that it absorbs moisture. In addition to absorbing moisture it also runs through copper lines and inevitably transfers residual or microscopically fragmented copper through the brake system.
Most late model vehicles have a tire pressure warning indicator lamp. If this lamp is coming on after the vehicle has been sitting overnight or on cold mornings and it goes out after a few miles of driving, then your tires are getting low.
Usually, the low tire pressure lamp will come on if there is a 15% variance in pressure between the tires. Each tire has a tire pressure monitor in it. These sensors operate by battery. Battery life is usually 5 years. A low battery can also cause this lamp to come on.
You take your vehicle in for service and anxiously await what feels to be inevitable. Here comes your vehicle report card!
Here are a few simple things that you can do to be sure that you are not being taken advantage of.
