Quoted: 0 Post(s). (Thread Starter). Low tire pressure light is ON. It started to get a little colder here, and my tire pressure sign went on. i checked the pressure-it's 35 psi on all 4 tires-more than what's in the passport so i'm not sure what's going on. the light doesn't go off-it's been on for a week now.uoted: 0 Post(s).

The proportioning valve only lets a certain portion of the pressure through to the rear wheels so that the front wheels apply more braking force. If the proportioning valve were set to 70 percent and the brake pressure were 1,000 pounds per square inch (psi) for the front brakes, the rear brakes would get 700 psi.
