If I disconnect my battery to clean the terminals, or change out the battery will I need to enter a code number to start the car again ? This may sound silly, but I had read where a fellow disconnected his battery to replace it and the car would not start afterwards.

 

you need a code for the radio, not the car.

 

Thank you Gilber33. I do have the code for my radio.

 

You will need to lock and unlock the car with the alarm remote or the door key or the car will not start.

 

Thank you RSPI !
I read on a previous thread about a fellow could not restart his 850. No one ever told him what you told me. I hope he figured it out.
I bought my 1995 Volvo 850 GLT in July 2009. I have been reading my owner's manual and visiting this site ever since then ! I really like this car but there is an awful lot of information one MUST know compared to the previous cars I owned. I GREATLY appreciate that you and others like you freely share your knowledge here !

 

Yes, it's tough owning and driving an older car. You have to do things youself if you want to save big bucks.

 

Actually, I love owning old classy cars like a Volvo or Mercedes. I could never afford to buy such a car new ! My last Volvo was a 1964 P544 I bought when I got out of the Army in 1970. It was far easier to work on than my 1995 Volvo. Personally, I am more endeared to a car that I have worked on. It ran like crap until I changed the timing gear. I find working on my car rewarding. I do not feel that I really own a car unless I have popped the hood and did something. Although now I have aged into my sixties and do not or cannot do all of the type of repairs as I did in my younger days.
The battery in my Volvo is a 'Volvo brand'. I have no idea how old it is. There are no dates on it. I do not intend to drive the car until it fails on some cold winter morning. I 'inspect' every car I have bought, then I take it to my mechanic for a second opinion to see if there is anything else that should be changed out.
I have learned a lot from this website and there is more for me to learn !

 

I have never had to do that, and I have changed and disconnected my batteries many many times.
