SERVICE TIRES SOON (mideast export)
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) illuminates the SERVICE TIRE SOON message when the vehicle communication interface module (VCIM) determines that the tires have to be changed. The IPC receives a class 2 message from the VCIM.
