Here are the methods to turn off the start-stop function on XT5: 1. If the vehicle is equipped with a start-stop function switch, you can turn it off directly. The location of the start-stop switch may vary depending on the model. 2. While driving, simply press the brake pedal firmly. After the vehicle comes to a complete stop for about two seconds, the engine will automatically shut off. Keeping the brake pedal pressed will maintain the engine in the off state. Once you release the brake or turn the steering wheel, the engine will restart automatically, allowing you to press the accelerator to move forward immediately—all while remaining in D (Drive) mode. The Cadillac XT5 comes standard with the START/STOP intelligent start-stop system. This system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a traffic light). When it's time to move again, the system restarts the engine automatically.

Turning off the auto start-stop function on the XT5 is quite simple. Every time you start the car, immediately look for the button with a circle and an "A" symbol located either below the left side of the steering wheel or on the center console. Press it firmly—when the button light turns on, it means the system is disabled. When I first bought my XT5, I found the auto start-stop very annoying as the engine would suddenly shut off and then jerk upon restarting, making the ride uncomfortable, so I developed a habit of turning it off right after starting the car. While this feature saves a bit of fuel, its impact in city driving is minimal. It can be convenient when stopping at traffic lights, but I personally prefer a quieter driving experience. The button location may vary slightly depending on the model year—for example, the 2020 model places it near the instrument panel, while newer models might move it to the touchscreen. Before operating, ensure the engine is running and avoid tampering with other settings that could affect driving safety. Regular battery checks can also help prevent auto start-stop failures.

The auto start-stop mechanism in the XT5 is automatically activated. As someone who enjoys DIY car modifications, I found that turning it off is as simple as pressing the start-stop disable button on the center console immediately after starting the car. This button usually has an identification label or indicator light that illuminates to confirm deactivation, and the operation takes just one second. Note that the system resets every time the ignition is restarted, requiring you to repeat the process—there's no permanent shutdown option, as this design prioritizes environmental protection and regulatory compliance. However, if you frequently drive on highways or encounter heavy traffic where the frequent engine restarts may increase wear, it's advisable to disable it only when necessary. Additionally, voltage issues, such as an aging battery, might cause the button to malfunction; in such cases, a visit to the dealership for a circuit check is recommended. Overall, the XT5's setup is more intuitive than some German models, with a clearly positioned button that's easy to locate and operate—even beginners can master it instantly. Just remember to buckle up; safety always comes first.

The start-stop system can be distracting while driving. For safety, I recommend pressing the start-stop button next to the steering wheel to turn it off immediately after starting the XT5's engine. The button is small but easy to find, usually located in the left-hand control area—just press it until the light comes on. Driving becomes smoother after deactivating the system, especially in traffic jams, reducing the annoyance of frequent engine shutdowns. The XT5's design doesn't remember the setting, so you'll need to disable it manually after each restart. Before operating, sit in the driver's seat with your hands on the steering wheel to avoid accidental touches. While start-stop saves fuel, it compromises comfort and safety—personally, turning it off is better. In case of engine stalling or issues, seek maintenance promptly. Safety comes first, and driving habits matter. Remember, avoid pressing any buttons before shutting off the engine.

I don't like the jolt from the XT5's start-stop system, so I always press the start-stop button to disable it before driving. The button is located near the air conditioning controls on the center console—just press it once, and the indicator light turns on, making the ride much more comfortable. The system defaults to engine pause at startup, but in city driving, the frequent restarts create strong vibrations. Turning it off makes the drive much smoother, even though it slightly reduces fuel efficiency—the improved comfort is worth it. The operation is simple: start the car and quickly find and press the button without delay. The button design varies by XT5 version—older models have it next to the knob, while newer ones integrate it into the touchscreen menu—but the core steps remain the same. Remember, disabling it is only temporary; you'll need to repeat the action every time you start the car. Keeping it off long-term won't harm the vehicle, but occasionally using the system helps maintain health. For a better driving experience, start with these small details.

The XT5's start-stop feature is designed for fuel efficiency and environmental friendliness, but if you find it annoying, you can disable it by pressing the start-stop button on the center console or steering wheel immediately after starting the engine. The illuminated indicator light means it's deactivated, and the operation is as quick as lightning. Although the system resets to default every time the vehicle restarts and requires manual deactivation again, this has minimal impact on daily commutes. I appreciate it from an energy-saving perspective, but the frequent start-stop cycles can be a learning curve for new drivers. Turning it off results in smoother driving, especially on long trips, by reducing engine load. The button location varies slightly by model year—for example, it's near the dashboard in base models and within the screen in luxury versions. Ensure you operate it safely without distraction, adhering to traffic rules. An additional tip: maintaining the well can extend the start-stop system's lifespan. Ultimately, just choose flexibly based on personal preference.
