How to Start a Mustang?

First, turn the key to the second position, where the vehicle's components begin to power up, and the onboard computer starts self-checking. During the self-check, the vehicle will emit a sound prompt. Once the prompt sound stops, it indicates that the onboard computer has completed the self-check. At this point, press the clutch and ignite to complete the starting process.

I've driven my friend's Mustang GT quite a few times, and starting it is actually pretty straightforward. After sitting in the driver's seat and fastening the seatbelt, keep the brake pedal firmly pressed. Then, with your right hand, locate the round start button with the Mustang logo on the right side behind the steering wheel and press it firmly. At this point, the dashboard will light up, the tachometer needle will jump, and you'll hear the engine's deep roar. For manual transmission models, make sure to fully depress the clutch before starting, or the start button won't respond. In summer, I usually let the engine run for about half a minute before shifting gears to allow the oil to fully lubricate. If you encounter starting difficulties, it's likely due to a weak battery or a dead key fob. In such cases, try placing the key fob against the start button before pressing it—this usually solves the problem.

Starting a Mustang feels like playing a racing game, full of ceremony. Keep the key in your pocket—no need to take it out—just open the door and get in. Press the brake pedal with your left foot—important things must be said three times! Press the brake! Press the brake! Then locate the red start button on the right side of the steering wheel. The moment you press it, the entire dashboard lights up as if activated. For automatic transmissions, just shift to D and go; for manuals, you’ll need to press the clutch and shift. Once, I forgot to press the brake and hit the start button—it only powered up without ignition, and the dashboard flashed a reminder to press the brake. Cold starts in winter sound especially dramatic, with the exhaust letting out a 'roar' that lets the whole neighborhood know I’m heading out. By the way, if the engine warning light is on, the RPM will be unstable after startup—get it checked immediately.

Last time at the 4S shop, I learned the Mustang's startup procedure from the technician. With the key within the car's sensing range, sit in the bucket seat and first confirm the gear is in P or neutral. Pay special attention to pressing the brake pedal firmly until the brake lights illuminate. Locate the START ENGINE button below the center console, press and hold it briefly for about 1 second. During startup, observe the dashboard closely: the oil pressure light turning off indicates proper lubrication, and the battery light extinguishing confirms normal charging. For newer models with power-latching doors, ensure the doors are fully closed before starting. Modified exhaust Mustangs produce loud cold-start sounds—don't be startled. If you forget to disable the auto start-stop function, the engine will automatically shut off at red lights; a light tap on the accelerator will restart it.

When helping my cousin pick up his Mustang, I specifically researched the starting differences between models. For the regular version, you just need to press the brake and push the start button. However, the Shelby GT350 is a bit special—you have to hold the start button for three seconds to wait for the vehicle system self-check to complete before starting. For manual transmission models, you must fully depress both the clutch and brake simultaneously; otherwise, the anti-theft system will lock. Once, it failed to start on a rainy day, and I later found out it was because the key signal was interfered with by being placed next to a phone. I recommend placing the key alone in the cup holder. In winter, don’t rush to rev the engine after starting—wait for the RPM to drop from 1,200 to 800 before driving. The new models with remote start are especially practical; you can start the car three minutes in advance with the key, and by the time you get in, the seat heaters are already warm.

Veteran drivers who modify Mustangs all know a few starting tricks. For models with keys, turn to the ACC position and wait for the instrument panel to complete self-inspection before ignition. For keyless models, ensure the anti-theft indicator light is off. Manual transmission models must depress the clutch fully to avoid burning out the starter. Those with modified intake systems should be cautious, as backfire might occur during startup. After starting, don’t rush to turn on the AC—wait until the coolant temperature gauge begins to move before engaging the compressor. If the car struggles to start after long-term parking, try pressing the accelerator to provide initial air intake. Once at a track day, a fellow Mustang owner couldn’t start his car—it turned out the steering wheel lock was stuck; a slight turn left or right fixed it.
