A hitch that was engineered to carry all of the tongue weight of the trailer.

A hitch that incorporates spring bars that “distribute” some of the weight from the rear of the tow vehicle forward, and some of the trailer tongue weight rearward. This helps keep the tow vehicle and the trailer at the same even level for better handling. A weight-distributing hitch may also incorporate a cam- or friction-type sway control that helps prevent or reduce trailer “whip.”

Keeps you well coiffed, even with the top down. This clear acrylic or mesh panel mounts upright behind the rear-seat headrests, helping to create a calm pocket of air in the open passenger compartment of a convertible.

A small vertical panel that rises along the leading edge of an open moonroof, helping to reduce unpleasant wind buffeting in the passenger cabin.

A music media format that can be played in vehicles with MP3/WMA capabilities.

Frozen windshield wipers won’t do you much good, will they? So this heating grid is built into the lower part of the windshield on some models, right where the wipers park. The de-icer activates when the heated mirrors are turned on (in some vehicles, it activates when the rear defroster is activated), helping to melt ice that forms on the wipers.

Makes sense when you think about it. Poor weather conditions can impact a driver’s view down the road, not to mention a driver’s visibility. With these facts in mind, on some Toyota models the windshield wiper switch is linked with the headlights. This way, when the wipers are turned on, presumably in poor weather, the lights come on too.

This system uses infrared signals coming from the rear video display assembly to allow rear-seat passengers to listen to audio programs without the use of wires.

The physical network of wires needed to power and connect a vehicle’s electric and electronic features.
