November 2010). "Biomechanical and injury response to posterolateral loading from torso side airbags". Depending on the type of vehicle, more specialized instruments may be used such as a trip computer, fuel economy gauge, or battery level display. Foundation components are the brake-assembly components at the wheels of a vehicle, named for forming the basis of the rest of the brake system.
For answers to frequently asked questions about the Megawatt Charging System and SAE J3271, see the fact sheet on Charging for Heavy-Duty Electric Trucks from Argonne National Laboratory. Electric companies may use red. Consumers and fleets considering electric vehicles-which include all-electric vehicles and plug-in hybrid electric vehicles (PHEVs)-need access to charging stations. BMW were among the earlier automakers to begin equipping vehicles with ESS. In California, emergency vehicles must display at least one forward-facing steady-burn red light. An above door mounted light system designed to light up the walking area around school buses. Blue lights and sirens may also be used on vehicles of that belong to private companies or organizations if their role is either life saving or protecting some vital system of society.

This has traditionally been operated by a lever between the front seats called a hand brake, but also appeared as a lever between the driver's seat and the door (as in the Porsche 911), a knob pulled away from the dash (as in the Volkswagen Transporter), a foot-operated pedal (as in the Nissan Leaf), and other less common arrangements. The turn signal lever is usually activated by a horizontal lever protruding from the steering column. Engine performance is looking for maximum displacement (bigger, more power), while fuel economy is looking for a smaller displacement engine (ex: 1.4 L vs. In the US 2017 model year, Toyota sold more vehicles equipped with collision warnings than any other single brand with a total of 1.4 million sold or 56% of their fleet.
