Our beginner's guide to baffling words, confusing terms and techy talk
We recognise that, for many people, entering a garage or workshop is like visiting another world. A world where the locals, although friendly and welcoming, do speak a bizarrely different kind of language. So, at all HiQ Centres, we always make a point of talking in plain and simple English. Because the last thing we want to do is make you feel uncomfortable or that you don't really know what's going on with your car.
However, vehicles these days are complex. So some understanding of the basics can save yourself a lot of confusion and concern - which is why we've put together or glossary of common terms and phrases. If you can't find what you're looking for here, feel free to pick our brains when you come in. Or get us to explain anything you don't understand if you speak to us on the phone. Our technicians are always happy to help.
Your A to Z of motoring gobbledygook
ABS (Anti-lock Braking System)
This is a series of sensors that are used to prevent the car's wheels locking and causing a skid when you press the brake pedal. By automatically releasing and then re-applying the car's brake pads in rapid succession it allows you to maintain control while reducing speed in extreme circumstances.
Airbags
These inflate immediately in an accident to create a cushion between you and any hard surface. Most new cars have an airbag in the steering wheel and a passenger airbag in the dash but other bags can be located in the seats or doors. A rear-facing child seat should never be placed in a passenger seat opposite an airbag because the force of the explosion which inflates the airbag could injure the child.
Alignment
This refers to the correct vertical alignment of the tyre when your car is at its normal ride level. Having your wheels aligned ensures that they are all pointing in the right way. If the wheels are not aligned correctly, the car will not handle properly and it could adversely affect tyre wear and your fuel economy.
All season tyres
These are tyres that are designed to be used all year round, in any weather.
Aquaplaning
This is the name given to the effect you experience when your tyres cease to make direct contact with the road surface because of water (your car is, in effect, surfing). As a result, you loose grip and traction and your car can go out of control.
Aspect ratio
This is the ratio of the sidewall of your tyre to the width of the tyre tread and is designed to help you distinguish between tyres of different dimensions. Expressed as a percentage ie. a tyre of 220mm width with a sidewall height of 110mm would be a 50 Aspect Ratio, or 50 profile tyre.
Asymmetrical
This is the name of tyres with a tread pattern that must be fitted in an indicated orientation. Often a chevron shaped pattern which assists the removal of water under the tyre
