The car has seven mechanisms triggered by buttons labeled from A to G on the steering wheel hub. Their functions are:

The Mach Five's steering wheel hub

• Button A, Auto Jack (オートジャッキ, Ōto Jakki, Auto Jack): Releases four jacks to boost the car up so that it can be repaired. Although designed for this function, the auto jacks are more often used to jump the car short distances, as a wedge to keep the car from toppling over a waterfall, or as an alternative braking system. The spring-like sound the jacks make is distinctive to the show.

• Button B, Belt Tires (ベルトタイヤ, Beruto Taiya, Belt Tire): Sprouts special grip tires for traction over any kind of terrain (firm, icy, or unsteady ground; ocean floor; vertical mountainsides). At the same time, 5,000 horsepower (3,700 kW) is distributed evenly to all four wheels (1,250 hp/932.13 kW).

• Button C, Cutter Blades (カッター, Kattā, Cutter): Powerful rotary saws protrude from the front of the Mach Five to remove obstacles in its way such as trees. Mostly used for racing in forest areas (especially when Speed gets forced off the road).

• Button D, Deflector (ディフェンサー, Difensā, Defensor): Releases a powerful deflector which seals the cockpit in a bullet-proof and crash-proof, and either an air-tight or water-tight chamber depending on the environment around the car. Inside it, the car driver is completely invulnerable.

• Button E, Evening or Illuminating Eye or Special Illumination (イブニングアイ, Ibuningu Ai, Evening Eye): The control for special illumination which can be traversed singly or in tandem, which enables the driver to see much farther and more clearly than with ordinary headlights. When used with the “night shades” attached to Speed's helmet, his vision is enhanced with infrared light. Button E was later modified to activate mini-wings (Pops got the idea from the Car Acrobatic Team) that would slide out from under the car to assist Speed in long jumps.

• Button F, Frogger Mode (フロッガー, Furoggā, Frogger): Used when the Mach Five is under water. First, the cockpit is supplied with oxygen. Then, a periscope is raised to scan the surface of the water. Everything that is seen is relayed down to the driver's seat by television. The 100-pound (45 kg) auxiliary supply of oxygen is enough to last for thirty minutes.

• Button G, Go Homing Robot (ギズモ号, Gizumo-gō, Gizmo): Releases a homing robot bird from the front of the car. The homing robot bird can fly and can carry pictures or tape recorded messages, handwritten messages, X-ray film, rope, and small Egyptian statues, and it has been used as a last resort as a makeshift weapon for means of defense. The bird-like device is operated by a built-in remote control within the cockpit.

• Button H, Homing Device (ホーミング, Hōmingu, Homing): This button is, unlike the other buttons, not located on the steering wheel; instead is located on a console between the seats. Button H is part of the Go Homing Robot's controls, and it simply sends the robot "home” to a pre-programmed location, usually Speed's house.
