Tire Pressure indicator

The TPS sensor may be dirty or defective...be sure all tires are above 33 psi...

Look in your owners manual

It means you have a malfunction in the TPMS system. First you can try to do a reset as follows: 1. key on, engine off, parking brake on. 2. turn park lights on and off 4 times you will hear a horn chirp twice, you are in program mode. Start at L/F tire release air for 10 seconds, wait 15 seconds until horn chirp, after chirp go to R/F tire do the same until horn chirp then R/R let air out til the chirp then L/R do the same after the L/R chirp, turn key off and you are done, note you have only 5 min. to complete. If you do not hear horn chirp at each tire, you will have to start from beginning. When complete, remember to add air to each tire, 35 psi is recommended.
If that does not work you probably have a bad TPMS sensor, which will have to be replaced. Some auto parts stores will test your sensors for free, so check around.

Front Tire pressure 30 psi.
Rear Tire pressure 28 psi.

That signal is from your tire monitoring sensors, telling you that there is air pressure difference between tires. The tire pressure should be same in all tires.

32 psi is the usual recommended pressure but you may have to fill the tires to 35 psi to make the TPM system reset. That's how most systems recognize that you have serviced the tires. Most TPM systems will indicate low tire pressure around 26-28 psi.

Depens on what tires you have on it. Most are 35 psi max. Some goodyear are 44 psi. the Max pressure will be printed in small raised letters on the sidewall of the tire. If 35, then 30-32 rear and 32-35 front is good depending on your load( many large people with trunk loaded, or just yourself. Higher front pressure accomodates for engine weight. A higher pressure, 35 all around, will give a harsh ride. Fuel economy suffers with low pressure. A compressor to fill the tires with from a cigarette lighter is available with a guage for under $20 and is very handy to have in the trunk. It can allow you to make it to a repair shop if you develop a slow leak and to keep pressure proper for extended tire life. If squeeling around corners is heard it is a good indicator that pressure is low. Frequent checks with a guage is important because pressure can be significantly low and not be apparent even to a fairly trained eye, especially on low profile tires. Please rate answer.

Sounds like the low tire pressure indicator. Check your tire pressure is correct in all four tires. This happens when the tempature outside starts to drop and so does the pressure in the tires. The recommended tire pressure should be listed on the inside of the driver's side door. Most tires are 32 psi cold. After the tires have been filled to proper pressure it may take 15 minutes for the light to shut off.

this is covered by warranty if it is not just a low pressure concern. Did you chek your owner manual to see if you need to reset? Did you check the spare?

should be a button in the fuse pannel. if not look in owners manual
