How to Use the One-Button Start in Lexus UX?

Lexus UX one-button start usage method: 1. After the driver sits in the driver's seat, there is no need to step on the brake, just press the start button once; 2. The ACC light will turn on, press the start button again for vehicle self-check; 3. Step on the brake and press the start button once more to ignite and start the engine. The design concept of Lexus UX is prominently reflected in its exterior. The front and rear fenders are tightly integrated with the body shape, extending outward and backward from the spindle grille to envelop the entire vehicle. The hood and bumper are not connected with the headlights and spindle grille. The compact rear design contrasts with the flared fenders. Design details such as the arrow pattern above the headlights and daytime running lights further highlight the Lexus family-style L-shaped headlight design. The mesh spindle grille radiates outward from the L emblem, creating a visual effect that changes with perspective. The two tail light units are connected by a linear tail light spanning across the rear door, giving the Lexus UX a unique rear styling.
As a frequent driver of the Lexus UX, I find the one-touch start feature incredibly simple to use. First, get into the car with the smart key, ensuring the key is inside the vehicle. Then, press the brake pedal all the way down and press the start button next to the steering wheel. The engine will start right away. When I first tried it, I was a bit confused, but my friend told me the key step is to press the brake—otherwise, the button won’t respond, and the car will only power on without ignition. It’s important to keep an eye on the key battery; if it’s low or the key isn’t present, the system will beep a warning. The advantage of one-touch start is convenience—no need to insert and turn a key. After starting, the car automatically adjusts to your last settings, like air conditioning temperature and seat memory. Occasionally, minor issues arise, like the car not detecting the key, so I check if it’s buried too deep in my pocket. Overall, this small feature is especially handy in rainy weather or when carrying items. Once you get used to it, you’ll find it indispensable.
I'm quite interested in automotive technologies, and the one-touch start system on the Lexus UX works quite ingeniously. You need to have the smart key inside the vehicle and firmly depress the brake pedal. At this point, the in-car sensors will detect your action and the key signal. Pressing the start button then activates the engine. The entire process is like an electronic signal conversation, ensuring secure ignition. If you don't press the brake, the button only turns on the power supply without starting the engine – I've tried warming up the cabin in winter by turning on power first before ignition. Remember to replace the key battery regularly to avoid sensor failure; when parking, simply press the same button to turn off the engine. The one-touch start design reduces mechanical wear, saves fuel, and is environmentally friendly, making daily drives more efficient.
I'm a new driver who just bought a Lexus UX, and it took me some time to learn the one-touch start. Step one: sit in the driver's seat, don’t forget to keep the key nearby; step two: press the brake pedal firmly all the way down; step three: locate the start button near the steering wheel and give it a gentle press—the engine will start right up. My first few attempts were trial and error—I kept pressing the button without stepping on the brake, and the car only lit up the screen without igniting. It wasn’t until a friend demonstrated that I understood. This little feature is so convenient—no need to take out the key, and the startup is lightning-fast. If you occasionally make a mistake, don’t panic—just press the brake again and restart. As a beginner, I think reading the manual more often helps you get the hang of it quickly.
