Questions regarding 2002 Monte Carlo

I bought my used 02 Monte several years ago. For the most part it has run good but it never came with the owner’s manual. Which leads me to my questions:



1) Since it didn’t come with the manual I naively assumed that, even if it wasn’t required, using 89 octane gasoline would be better than using 87. I’m now discovering that that is not the case. In the interest of saving money and the enviroment I’d like to downgrade. After using 89 for a good 4 to 5 years would switching down to 87 damage the engine?



2) The “Low Tire Pressure” light came on. I filled up the tires but can’t figure out how to turn the light off. Does anyone know how to do this?



Thanks in advance for the help.

See if there’s a sticker on the doorjam that indicates the octane requirement. Or you could call the local dealer who can look it up for you. If it says you can use 87 octane, than you can, no matter what you’ve used fore the past years.

While you have the dealer on the phone, ask him how to reset the low pressure warning light. Different cars have different protocols. Mine has a button in the glovebox.

The owner’s manual contains a lot of useful information. I recommend buying one. Even ordered from the dealer it shouldn’t cost more than $20 or so, a worthwhile investment, IMHO.

You need an owner’s manual, and perhaps a shop manual.

Try Books4Cars.com for inexpensive used owner’s and/or shop manuals.

And, No, I’m not connected with Books4Cars.com.

I’m just a satisfied customer.

Register on gmlink.com and you’ll be able to download an electronic copy of your owner’s manual or go on-line whenever you want to peruse the owner’s manual…I use gmlink.com for my 1996 Buick LeSabre so I’m pretty confident you’ll be able to find the book for an 2002 Chevy Monte Carlo. Good luck!
