To check the tire pressure on a Jeep Compass, simply view the tire pressure monitoring display on the instrument cluster. The tire pressure monitoring system automatically monitors tire pressure in real-time while driving and alerts the driver in case of tire leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring systems: Direct TPMS: Direct tire pressure monitoring systems use pressure sensors installed in each tire to directly measure air pressure. Wireless transmitters send pressure data from inside the tires to a central receiver module, which then displays the pressure readings for each tire. The system automatically alerts the driver when tire pressure is too low or if there's a leak. Indirect TPMS: When a tire's pressure decreases, the vehicle's weight causes that wheel's rolling radius to become smaller, making it rotate faster than other wheels. By comparing rotational speed differences between tires, the system monitors pressure. Indirect systems essentially monitor pressure by calculating changes in tire rolling radius. Tire Pressure Monitoring System (TPMS): This combines the advantages of both systems above. It installs direct sensors in two diagonally opposite tires while using a 4-wheel indirect system. Compared to full direct systems, this hybrid approach reduces costs while overcoming the indirect system's inability to detect simultaneous underinflation in multiple tires. However, it still cannot provide real-time actual pressure data for all four tires like a full direct system.

Checking the tire pressure on my Jeep Compass is quite simple. After starting the car, just press the small arrow button on the left side of the steering wheel to cycle through the display options on the instrument cluster. Keep pressing until you see the numbers for all four tires. Sometimes it may take half a minute after starting or driving a few hundred meters for the readings to appear, so don’t jump to conclusions about a malfunction. I recommend taking a quick look every morning after starting the car—both over- and under-inflation need attention, especially before highway driving. I usually maintain around 2.4 bar; it’s slightly lower when the car is cold in winter but rises as temperatures increase. If the tire pressure is off, get it adjusted at a shop promptly—even a 0.5 bar difference is noticeably felt while driving.

You see that row of buttons on the left side of the steering wheel, the one with a small menu icon printed on it? That's the information toggle button. Press it once to switch the dashboard display, and after pressing it three or four times, you'll see the tire pressure values displayed individually for all four wheels. If a yellow tire pressure warning light appears in the center of the dashboard, it means there's an issue with one of the tires. The new Compass also allows you to find the tire pressure monitoring page in the vehicle settings on the central control screen. Remember, tire pressure will be about 0.2 bar higher after highway driving compared to when the car is cold, which is normal. It's best to carry a portable air pump in the car. If you notice the pressure is below 2.0 bar, top it up first.

Start the engine and locate the control button with an arrow on the left side of the steering wheel. Press it several times until the tire pressure data is displayed on the instrument panel. It is recommended to check on a flat road surface for more accurate readings. If horizontal lines appear instead of numbers, it indicates a loss of sensor signal, which can be restored by driving a few hundred meters. The system will alert you when the tire pressure is abnormal, and a yellow light on the instrument panel will prompt you to check the tires. Develop a habit of checking before daily driving, especially when carrying heavy loads or going on long trips. Remember to regularly check the spare tire pressure, as many vehicles' spare tires slowly lose air over time.

Press the buttons on the left side of the steering wheel to switch the dashboard display, and stop when you see the tire pressure values. New cars may need to drive for a few minutes before initial data is displayed. The recommended tire pressure values are written on the sticker on the driver's door frame, usually between 2.3 to 2.5 bar. In northern winters, tire pressure may be about 0.3 bar lower in the morning and will automatically recover as the temperature rises. If one tire consistently shows 0.5 bar lower than the other three, it might have a slow leak. Incorrect tire pressure can affect steering wheel resistance and fuel consumption. My car saves half a liter per 100 kilometers when the tire pressure is correct. It's best to reset the system after repairing a tire.
