Hyundai AC Switch Any of several switches used to control various functions of an AC system.
Hyundai AC Tensioner Pulley A circular pulley used to set the tension on the AC belt.
Hyundai Accelerator The gas pedal. Pilots & gearheads sometimes call this the "throttle." Call it what you will, pressing down on it should encourage the car to accelerate. Simple enough.
Hyundai Accelerator Pump If you're one of the few souls that still has a carbureted engine, you've got an accelerator pump that provides an extra squirt of fuel to enrich the air/fuel mixture & thus enable the car to accelerate when the gas pedal is depressed.
Hyundai Active Noise Control (ANC) A program used to control noise in the engine. Therefore, a loudspeaker is installed in the intake system, & this generates a sound wave of the same amplitude, but it has an opposite phase. It cancels out the noise.
Hyundai Adaptive Cruise Control (ACC) An adaptive cruise control system can actually scan the area for objects in front of the car. Brakes automatically if the object is close.
Hyundai Additives Additives are substances added to such products as coolant & engine oil so as to enable them to perform better, last longer, & provide secondary benefits.
Hyundai Air Bag The air bag, also known as a Supplemental Inflatable Restraint System, is a passive safety device, supplemental to safety belts, that inflates to provide a cushion to absorb impact forces during moderate to severe frontal collisions. This system can help to lessen the chance of contact with the steering wheel, instrument panel & windshield. The air bag is actuated automatically by sensors located in the front of the car. To maximize effectiveness, seat & shoulder belts must always be used in conjunction with this system

Hyundai Air/Fuel Mixture This is what is sounds like it'd be--the mix of gasoline & air that allows your engine to produced power. There is an ideal ratio of air to fuel that is most conducive to a complete burn of the gasoline, which is 14.6 parts air to 1 part air, also known as the "stoichiometric ratio." (I challenge you to work that into a sentence sometime int he next 6 days without the person you're talking to noticing.)
Hyundai Airfoil An aerodynamic device designed to improve traction by increasing the downforce on the car. The use of airfoils (also called wings) increases the cornering capability & improves stability at speed, but often at the expense of additional aerodynamic drag.
Hyundai Alignment Alignment refers to the angle your tire contact the pavement, & is usually measured in degrees positive or negative. Alignment is suprisingly important, affecting the way your tires wear, the tendency on your car to travel straight (versus pulling to one side or another), & overall steering "feel."

All-Wheel Drive automatically splits engine torque between the front & rear wheels as needed, improving on-road traction in unfavorable road conditions. Unlike Four-Wheel Drive, All-Wheel Drive is an on-road system & is not designed for off-road use. AWD does not require the driver to actively engage the system. It is operational at all times, & requires no switches, lights or visor instructions for system operation.
Hyundai Alternator An electrical device which is driven by a fan belt or serpentine belt which generates DC electrical current & sends that current to the battery so as to keep it charged.
Hyundai Alternator Tensioner Pulley A circular pulley with a bearing which is used to tighten & keep the correct tension on an alternator belt.
Hyundai Anti-Lock Brake System (ABS) On a car equipped with Anti-Lock Brakes, the wheels are equipped with speed sensors. When a sensor determines that a wheel is decelerating so rapidly that lockup may occur, the electro-Hydraulic Control Unit (EHCU) is activated. The EHCU then modulates the brake pressure in the appropriate brake lines by means of the solenoid-operated valves. This is intended to prevent wheel lockup & help the car maintain directional stability during potentially hazardous braking situations. (See also: Rear-Wheel Anti-Lock & Four-Wheel Anti-Lock.)
