Straight Ahead (Wheel Alignment)

If every road was straight and smooth, we wouldn't have to worry much about wheel alignment. But they're not, so we do.  Hitting potholes or driving on rough pavement can knock your vehicle out of alignment and you'll notice it in one of several ways.

Your steering wheel may not be centered when you're driving straight ahead, or your vehicle may pull to one side.  You may find your tires wearing on one side or they may squeal.  All are signs that could point to you needing an alignment.

Your wheels should be perpendicular to the road and parallel with each other.  If not, your tires will wear out faster and your vehicle won't go straight on a level straightaway.

In alignment, there are several factors that must be checked.  One is camber.  Your wheels should be straight up and down if you look at them from the front. If not, you'll wear your tires unevenly on one side.

Another factor is caster, the angle of the steering pivot.  Most vehicles have what's called positive caster, when the top of the steering pivot leans toward the rear.  Proper caster balances steering effort, stability on the highway and cornering.

You may have heard the term "toe" in reference to your wheels.  If you looked at your front wheels from straight above, for example, imagine your wheels were your feet.  If you were to turn your toes in toward each other, that would be toeing in.  The toe of your vehicle should be set to manufacturer's specifications so your vehicle handles well and doesn't prematurely wear out tires.

It's a good idea to have your alignment checked periodically since it can get knocked out by one hard knock or a lot of little knocks.  It's not just about tire wear, it's about ride comfort and safe handling. You may say a vehicle aligned just feels divine.

When Your Air Bag Light Comes On (Illuminated Air Bag Light)

There are some dashboard lights you should pay more attention to than others.  One is the air bag light.  If it's on and your vehicle is in an accident, your air bags probably won't do their job.

Automakers began installing air bags in the late 1990's since they were mandatory in the United States, and manufacturers have included them in Canadian vehicles as well.  Safety experts say using a seat belt in combination with an air bag gives passengers the best chance of surviving a crash and minimizing serious injury.

The air bag warning light takes a few different forms.  Some look like a picture of a belted passenger with an inflated air bag from a side view.  Or there may be a warning light that says something like "Air Bag," "SRS" (for supplemental restraint system), "Airbag Deactivated" or "Air Bag Off."

Different things cause the air bag light to come on.  Your vehicle may have been in an accident during which, while the air bags didn't inflate, crash sensors were activated.  Some of them may be connected with your vehicle's seat belts.  A technician can reset the air bag if this has happened.

Fuses can also blow which will cause the air bag light to come on.  Another possible cause? A sensor that tells the vehicle's computer whether or not there is someone riding in the passenger front seat may be malfunctioning. 

Air bags are not for the do-it-yourselfer.  They are sophisticated systems that require specialized training and equipment to diagnose and repair.  If an air bag light is on, take it to a qualified service repair facility.  One more thing: remember that safety experts have designed air bags to work in conjunction with seat belts for maximum protection in accidents.  So always wear your seat belt.
