Under normal operation, You can get the TPMS light on the 2015 Cadillac SRX to reset itself on its own after You've inflated the ties to the correct pressure. Usually, You'll need to drive for a couple of miles of straight driving at over 20 mph for the computer to pick it up. However, if that hasn't worked, or You replaced a tire or sensor, You can also do it manually. Hop into Your Caddy and turn the ignition to the ON Position, but don't start the engine. Press the SEL button on the right side of Your steering wheel to enter into the Settings page. Scroll to INFO and press SEL to select it. Then, go to TIRE PRESSURE. Press and hold the SEL button until the horn chirps. If You were replacing a tire, at this point, You'd need to use the TPMS relearn tool at every tire, but that's an altogether separate thing; here, You should be able to turn the ignition off, and then start Your vehicle, with the light now reset.

To reset the tpms on the 2015 cadillac srx make sure the tire pressure is correct, then turn on the vehicle. Now hit the reset button that is to the right of the steering wheel and wait ten minutes. In some cases you may need to hold the button down till the light flashes. If the sensor is not working correctly then you may have tires with incorrect pressure, and the car can get bad performance.
