We have aflat and no owners manual(car purchased

take the car to a tire place.

Since the spare is mounted under the rear of the car, Its not easy...you have to assemble the long crank rod out of its two pieces, then feed the rod through the hole in the top of the rear bumper and lock it into the mechanism that holds the tire in place. Once the crank rod is locked in, lower the tire towards the ground. Once the tire is low enough, you can crawl under the car and release the tire from its mount. The hardest part is locking the crank rod into the spare tire mechanism through the hole in the bumper.

If the battery was sitting that long, it cannot store much energy.

Your TPMS Light is on,not flat tire

Read your owners manual


Have a tire store try to reset

You may have a failed sensor in the tire

Expect that to be a $100 repair

Service Tire Monitor means that one or more of your tires are underinflated, causing an out of balance condition that it can detect through the wheel speed sensors.

The code should be covered in your manual, to tell you how to reset it after the tires are inflated evenly to manufacturer's specifications.

I would check the sizes of all your tires to verify that they are the same type and size recommended by Cadillac. Also, check the tire inflation in all 4 tires to make sure they are even.

Then, follow the instructions in your manual on how to turn the 'Service Tire Monitor' light off.

If you don't have a manual, you might go to the Cadillac.com website and look under 'owners' and you can sign on to Yahoo! and get a free manual downloaded to your computer for viewing or printing, I believe.

It will come back on if the tires are unevenly inflated as you go down the road several miles.

Ford Windstars, also, have this feature. A lot of newer cars past the year 2000 have this feature which helps you to monitor the pressures and avoid getting a flat tire on a long trip.

Good luck travelling in your first Cadillac.

I have 3 Cadillacs at my disposal, a 1976 Seville, a 1990 Deville, and a 1997 Deville Limo and I love all of them, although the 1976 and 1990 need paint jobs here in Pennsylvania's harsh weather.

Hi,
When you purchased your new tires they should have reset the TPS Unit. On Some models it's the sensor in each wheel, on others it's the unit itself. I would go back to where you got the tires and have them reset it. If they don't know how, the easiest way to do it is look in your owners manual, and follow the instructions. Or go to the nearest Chevy Dealer and see if they won't help you. The Owners Manual is some times confusing, and may take a couple of tries to reset. When I was running a tire store it was a constant battle to reset everyone's TPS. As there is NO STANDARDISATION. !!! If you Don't have an Owners Manual, Please Contact Me and I will try to assist you further. You really need to learn how to do this yourself... that way you can take advantage of the tire sales that some of the smaller stores have, even though they might not be able to reset your TPS.
I Hope this Helps You !

P.P.S PLEASE RATE ME !

With the new 2008 models, the spare tire was moved from the rear of the van to a spot below the front seats. The lug for the tire winch is located under a round cover in the floor just in front of and between the two front seats. If you look under the van, you will see the black tire-shaped cover for the spare.

Never mind...I got a bright idea to read the owner's manual and figured it out. Doh!

could be low tire pressure or anti slip traction control was working. turn of your traction control and the light will stay on... or read your owners manual

normally a spare will not fit in the storage area of the corvette. most came with run-flat tires. it is also possible that the car came with a small compressor and some sort or liquid stop leak (ie tireslime) My best advice is to contact a local corvette club or dealer. they can tell you exactly what your vehicle is equipped with.
