How to Turn Off the Auto Start-Stop Function on the XT5?

[DeBennett]

Cadillac XT5's auto start-stop is an intelligent system where the computer determines driving conditions based on the frequency, duration, and force of brake pedal presses, automatically disabling the feature in congested traffic. Below is an introduction to the Cadillac XT5's auto start-stop function: 1. Many current vehicle models are equipped with both auto start-stop and auto hold features, combining effort-saving (no need to press the brake) with fuel efficiency. 2. Auto start-stop shuts off the engine, requiring the driver to keep the brake pedal pressed unless the vehicle is also equipped with auto hold. Releasing the pedal will restart the engine. 3. Auto hold locks the wheels, eliminating the need for the driver to press the brake pedal. Pressing the accelerator pedal serves as the release signal, allowing the vehicle to start moving again.

On my Cadillac XT5, the auto start-stop function defaults to being enabled every time I start the car. Turning it off is simple: locate the small button with an ‘A OFF’ symbol on the instrument panel or center console area, press it once, and the function is immediately deactivated. However, note that this is only a temporary solution—once you turn off and restart the engine, it will automatically reactivate, so remember to press it again before driving. I make it a habit to handle this every time I get in the car; otherwise, the frequent engine restarts at red lights cause slight vibrations that can be a bit annoying. If you find this troublesome and want to disable it permanently, I suggest asking the dealership if they can update the system or install a bypass module—though modifications come with risks, potentially affecting warranty or fuel efficiency (since auto start-stop is designed to save fuel). Occasionally turning it off is safe and has no major impact. In short, developing this small habit can make your driving experience smoother.

To be honest, the auto start-stop feature on the XT5 can be quite annoying sometimes. As an average driver, I always quickly press the button with the letter A near the steering wheel to turn it off right after starting the car. The light comes on to confirm it's off, but it doesn't stay off permanently—I have to do it again next time. After driving for a few years, I've noticed that the slight vibration during start-stop reduces comfort, so I've developed a routine: sit down, start the engine, and press the button. If this feature bothers you too, just keep at it—no professional tools are needed.

As an extra note, the XT5's auto start-stop is designed to reduce emissions and save fuel. Turning it off might increase fuel consumption by a fraction, but the difference in daily driving is negligible. Don't worry about harming the car—it's safe to turn it off occasionally, just remember to press the button again to avoid any awkward or inconvenient situations on the road.

The auto start-stop deactivation process is actually straightforward - simply press the button with the corresponding symbol on the control panel to disable the function. In the XT5, this feature resets after every ignition cycle, so don't expect it to stay permanently disabled. Here's my proven method: Immediately after starting the engine, locate and press that button until the indicator light confirms deactivation. Disabling it prevents unnecessary engine restarts and improves driving comfort. If you frequently forget to manually turn it off, consider either adapting to the feature or consulting your dealership about modification options, though manually pressing the button remains the most convenient solution in most cases.
