how many miles? does it idle in park ok? have it had a tune up ? have you tried a gas cleaner that you pour in the gas tank?

Once the tires are correctly inflated as per the required PSI, the light should go away, if not, follow these possible solutions. We are sure one of thse will work for you:
1. Drive at a steady speed of 50 mph for 10 minutes or higher, then switch off the engine, this may get the light to stop
2. Turn the key to the ON position and then press and hold the TPMS reset button located under the steering wheel. Check the car's manual to see where it's located. Hold the button until the TPMS light blinks thrice. Crank up the engine, and the sensor shall refresh within 20 minutes
3. Inflate all four tires to their recommended pressure plus three PSI more. Then deflate them entirely and then reinflate them to the recommended PSI
4. Remove the positive wire of the battery, switch on the car, and then press and hold the horn for three seconds to discharge any power left in the vehicle. Then reconnect the battery, and the problem should be solved.

There is a 'hard' code stored in the computer which can seriously adversely affect engine performance. Have a parts store scan the code for free, or buy and OBD-II Scanner ($98 or so plus tax at Walmart) of your own which can tell you in plain English what system is giving your car engine trouble.

There is a hold button on the shifter or the console. When activated the transmission is locked into the selected gear and the hold light will come on.

An example is putting the transmission in 4th gear, pushing the hold button, and taking off in the snow. Wheel slip would be limited.

You will need the check engine light code read with a scanner and diagnosed.

the word HOLD is up near the clock on a 2004 Chevy Aveo. "HOLD" lights up. I'm not sure about the 2005 Aveo.

THERE MUST BE A SENSOR PROBLEM YOU NEED TO CONNTACT A DEALER AND FIND OUT WHAT THE CODE REPRESENTS

check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.

Something that might sound really easy, but please check your gas cap, make sure its on real tight or the rubber seal is still good,if not, get a replacement before you try and get any mechanics to touch your car. It might save your big bucks! All the best and drive safe. Hollywood Harv

I doubt the gas cap is related to the light, though hopefully you can get a replacement for it because it can be dangerous. As for the check engine light I'm not sure what it could be. Is the car running making noises, does it stall?? If there are no obvious symptoms, you might need to take it to a mechanic so they can read the error message from the cars computer and determine where th eproblem is.
