Cadillac ATSL's seat ventilation requires aftermarket installation. Relevant information is as follows: 1. Function: The seat ventilation system continuously delivers cool air through small holes in the seat cushion and backrest, preventing sweat accumulation on the hips and back, and providing a comfortable riding environment. Seat ventilation is divided into front seat ventilation and rear seat ventilation. 2. Classification: Front seat ventilation is divided into air-supply type and air-suction type. The principle of front seat ventilation is to use a fan to inject air into the seat, which flows out through small holes on the seat surface to achieve ventilation. Seat ventilation effectively improves the air circulation environment between the body and the seat surface, ensuring that the contact area remains dry and comfortable even during long drives.

The seat ventilation in my Cadillac XT5 is super practical – no more sweaty back during summer drives. After starting the car, just look for the seat icon with a fan symbol below the center console and press it to activate the ventilation function, which usually offers high, medium, and low settings. If you can't find physical buttons, don't worry – the latest Cadillac models have virtual controls in the central touchscreen under the climate control menu. I recommend using the high setting initially for quick cooling, then switching to medium/low to maintain comfort while saving energy. By the way, the seat ventilation works like a turbo fan that draws away moisture, providing more even and comfortable cooling than direct AC airflow. For long drives, pairing it with the AC set at 22°C creates the perfect comfort zone.

The location of Cadillac's seat ventilation button varies in several scenarios: in older models like the ATS, it's a standalone button on the side of the seat; in newer ones like the CT6, it's on the central air control panel; and in the all-touchscreen LYRIQ, you'll need to navigate to the air conditioning menu on the screen. I'm accustomed to pressing the button with a fan icon below the seat heater button after getting in the car—when the light turns on, it means the ventilation is activated. There are three fan speed settings to choose from. During the scorching summer, I usually set it to the highest speed, and within seconds, cool air rushes up through the leather seat cushion. After prolonged use, I've noticed that this feature actually consumes very little power, as long as you don't run it simultaneously with the steering wheel heater for too long. If the button doesn't respond, it's likely a wiring contact issue—just take it to the dealership to read the fault code with a computer, and it should be resolved.

Operating the Cadillac seat ventilation is straightforward: After ignition, locate the button with the seat + fan symbol on the driver's side door panel or center console. Press once to activate ventilation, and repeatedly press to adjust the fan speed. For some touchscreen models, you need to access the air conditioning submenu via the center console. In actual use, the ventilation system draws air through small holes on the seat surface, creating airflow that cools more directly than traditional air conditioning. This feature is especially useful in the hot and humid weather of southern regions—I always turn it on during highway drives. However, be cautious not to place sharp objects on the leather seats to avoid puncturing the air ducts.
