How to Check Tire Pressure on Volkswagen Passat?
3 Answers
Volkswagen's new Passat can only provide tire pressure warnings and does not have a function to display tire pressure. Below is how the tire pressure alarm system works in the new Volkswagen Passat: 1. The tire pressure monitoring system "RKA+" in the new Volkswagen Passat uses ABS sensors to compare the rotational speed and rolling circumference of each wheel. 2. When the rolling circumference of a wheel changes, a warning light will illuminate on the instrument cluster. Below is additional information about changes in tire circumference: 1. Tire pressure is too low. 2. The tire structure is damaged. 3. The vehicle is carrying a load on one side. 4. Excessive load on the front/rear axle wheels.
To check tire pressure on the Passat, I usually rely on several methods. After starting the car, if the yellow tire pressure warning light on the dashboard illuminates (it looks like an exclamation mark), it indicates a possible abnormality. In newer Passat models, the central display may directly show numerical values—press the buttons near the steering wheel to enter the menu, navigate to vehicle settings or information, and select tire pressure to view specific readings. If these features aren’t available, a handheld tire pressure gauge is an affordable option; just insert it into the tire’s valve stem to get a reading. The label on the door frame lists recommended values, with different pressures for front and rear tires—I typically check each tire. Both underinflated and overinflated tires are problematic, leading to unstable driving, increased fuel consumption, or even blowouts. I make it a habit to check monthly, especially before long trips. For manual checks, park on level ground and measure when tires are cold for accuracy. These methods ensure both safety and fuel efficiency.
The Volkswagen Passat is equipped with a tire pressure monitoring system, which comes in two types: direct and indirect. The direct TPMS can display real-time pressure values on the dashboard or central control screen. After ignition, navigate to the vehicle information menu and find the tire pressure option to check. The indirect type relies on ABS sensors to detect differences in tire rotation speed and will only illuminate a warning light without displaying specific values. I recommend performing regular checks after system calibration. Using a Bluetooth tire pressure gauge or a mobile app connected to the OBD interface can provide more accurate data. For manual operation, use a tire pressure gauge to measure each tire's pressure. The recommended values are usually posted on the B-pillar or door edge, with front tires around 35 psi and rear tires at 33 psi, but always refer to the label for exact specifications. Abnormal tire pressure affects handling and increases wear. Maintaining correct pressure optimizes performance and reduces accident risks. Automatic tire pressure systems may malfunction, so keeping a tire pressure gauge as a backup is advisable. Recalibrate the system during seasonal changes to avoid errors.
