How to Install ETC on the Windshield?
2 Answers
ETC installation process on the windshield is as follows: Upon receiving the device, first check if the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU. A red light will briefly illuminate, and the OLED screen will display "Label Invalid" and "Please Insert Card," indicating the device is functioning properly. Clean the front windshield to ensure the glass surface is smooth, clean, and dry. Then peel off the protective film from the OBU's adhesive back and stick it to the installation position. Press firmly with your hand for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield, ensuring the chip is inserted into the OBU device. ETC installation position: For small vehicles such as cars and minivans, the ETC card and OBU device should be installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part. ETC installation requirements: The height should be no less than 1.2 meters and no higher than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the electronic tag surface and the horizontal plane).
As a new driver who just bought a car, I was a bit nervous when installing the ETC for the first time. First, prepare the ETC device and ensure it's intact. Then choose a suitable spot on the front windshield—I usually pick the area near the rearview mirror toward the roof, which won’t obstruct driving visibility or block any dashboard instruments. Cleaning the glass is the most crucial step: wipe off all dust and grease with a damp cloth, then thoroughly dry it with a dry cloth to ensure no water stains remain. Peel off the protective film from the double-sided adhesive on the back of the device, slowly press it onto the glass, and firmly press from the center outward for about 30 seconds to secure it. If small bubbles appear, gently smooth them out with a bank card or handkerchief. After installation, test it to confirm it’s firmly attached. Don’t rush the process—take your time to ensure the ETC works properly and avoids issues on the highway. Moving it after installation may damage the adhesive. I found this experience quite helpful—beginners can practice in advance by reading the manual.
