    Tire Pressure on dash lists tire pressure for opposite wheel??

    Hi everybody! We are looking at getting a 2007 DTS base from a friend. It has 127k on it so we're slightly weary of the mileage but it's in very good shape and hes selling it to us for $6750 so we feel it may be a good deal.


    One thing i noticed while driving and looking it over--when I filled the driver's side front wheel with air, the tire pressure on the dash was increasing for the "front right" tire instead of the "front left"?? is this normal, or is there something wacky with this car? Otherwise it seems fine, except when it first gets going, park assist seems to be repeatedly beep even while we are driving for about the first 50 feet--is that normal as well?

    Thanks guys!

    Have the tires been rotated recently? Saw this in an XTS once. The sensors moved and were not adjusted. It caused readings like that.

    Yeah, that's the only explanation. You're not using the dash as a gauge to Gil to the correct pressure, are you?

    The parking sensors should NOT beep unless you are real close to something....
    The tire pressure sensors just need resetting... that's no big deal.

    Don't wait for the instrument panel to scream Help! - open the hood once a week and check everything: fluid levels, general appearance, a little TLC cleaning, belt appearance.

    Always read the sticky posts in any forum of interest - especially those in Engines; Northstar. Study the entire Cadillac Technical Archive way up ^^^ in the top black bar. Read the owner's manual - twice.

    There is a specific procedure, using a strong magnet, to reset the TPMS sensors to read out the correct wheel. BUT - never trust the TPMS: use a good dial pressure gauge once a month to read tire pressures - cold, never hot. Tire pressure is set "cold" or after driving less than one mile from "cold". NEVER check or inflate or bleed hot tires. The "Maximum inflation pressure" stamped in the sidewall is what you would use on Bonneville Salt Flats - never in daily driving.

    I had noticed a similar thing going on with mine (front pressures were back, back were front) dealer took care of it for me when they had to fix a leaky tire for me.

    And yeah, learned my lesson about using the pressure sensor in dash as a tire gauge, doesn't work like that, don't try it! had my tire all the way to 41psi but I realized before I drove anywhere! Whew!

    Its in the owners manual. You start the relearn tire position sequence in the menu, deflate lf tire till horn sounds, then same with rf, rr, and finally lr. Takes about 2 minutes.

    I learned the hard way not to trust the sensors dash said tire was low so I thought i would fill tires per dash info. WRONG! I don't know how long it took me to realize the read out was not paired with the proper tire so I used my gauge and now I'm a somewhat less trusting but happier camper. mike

    Thanks guys! We quickly learned NOT to use the dash display to inflate the tires. I took the car to the place they got tires (turns out they were just 3 days old!) and they reset the sensors.
