How to Turn Off the Auto Start-Stop Function in the Teana?

When you don't need to use the auto start-stop function, simply press the auto start-stop button to turn it off. More related information is as follows: 1. The auto start-stop function automatically shuts off the engine when the vehicle comes to a temporary stop during driving. It automatically restarts the engine when the vehicle needs to move forward again. 2. The auto start-stop function is achieved by installing an enhanced motor with idle start-stop capability in the engine. The operation of the motor relies on the battery's power. If the auto start-stop function fails, it indicates a battery issue, which could be due to insufficient battery charge or damaged battery components, requiring further inspection and repair. This function not only helps the engine save unnecessary fuel consumption, reducing fuel usage by 10% to 15% annually, but also minimizes unnecessary exhaust emissions.
As a long-time owner of a Teana, I find the auto start-stop feature particularly annoying in traffic jams—it keeps shutting off the engine when stopping and restarting when moving, which feels like unnecessary wear on the engine. Turning it off is actually simple: after starting the car each time, just press a button marked with an "A" or a similar icon located below the steering wheel or on the dashboard. The screen might display an "Off" prompt. However, it reactivates automatically after every ignition, so my first move upon entering the car is always to disable it. I believe this design aims to save fuel, but it’s quite uncomfortable for city driving, and if the battery ages, it’s prone to malfunctions. During routine maintenance, ask the mechanic to check the battery condition to avoid system glitches affecting safety. If you really dislike using it, consider switching to a non-start-stop battery, though this isn’t officially recommended and may void the warranty. Ultimately, getting used to the routine helps—don’t let it ruin your driving mood.
From a mechanical perspective, I've helped a friend with the auto start-stop issue on their Teana. The system primarily saves fuel by using sensors to control engine shutdown, but it can be slightly sluggish when restarting at certain intersections. The deactivation method is simple: right after starting the engine upon entering the car, immediately locate the button on the center console (shaped like an 'A' or with a circular arrow) and press it once to disable the system for that trip. Note that this isn't a permanent deactivation – you'll need to repeat the process next time you drive. I recommend against permanent deactivation because the manufacturer's design includes safety logic that automatically disables the system when battery voltage is low. For greater peace of mind, regular battery checks can prevent start-stop failures from causing more trouble. Additionally, the system may default to inactive when the AC is on or during hot weather, but manual deactivation ensures consistently quiet driving and reduces vehicle wear risks. Once you get used to it, the process becomes quite convenient.
