An antilock braking system (ABS) moderates vehicle brake pressure in emergency-stopping situations. Instead of applying sudden, constant pressure to the brakes, ABS rapidly pumps them. ABS prevents the wheels and steering from locking up, causing the vehicle to skid and the driver to lose control. Locked wheels increase stopping distance and inhibit the driver from steering around the obstacle they’re trying to avoid.

A rear window defroster is an embedded or applied electric heating element that warms the rear window to rid the glass of fogginess and frost or loosen snow and ice. The defroster is usually activated by a button on the console or dash and sometimes with a remote start.

A tow hitch is an extension of a vehicle’s chassis that enables the vehicle to tow a trailer. A receiver attaches to the hitch to insert a ball mount. After a trailer ball is screwed into the mount, a coupler, extending from the trailer, hooks onto the ball. Once all the components are locked together, including chains (and sometimes wiring), the vehicle can drive and pull a trailer behind it.
