So I'm contemplating Hibernating my X come this winter. Probably from November to April.

I have an MR with Nav. No aftermarket alarms or killswitch. Stock.

My question is if I disconnect the battery on the car and let it sit all those months the NAV system, like most modern cars, will ask for a security code. Is this security code in the car or will I have to get it from the stealership?

 

Not sure about your X but in my IX they gave me one with the keys to the car. I would check your owner manual.

 

Yeah. I'll check my paper work.

 

Dont disconnect the battery, use one of those battery maintainers.

There are more things you need to do for winterizing your car. Putting Stabil in the tank would be one of them.

 

I disconnected my battery one winter while my car sat and the next spring when I went to start it the battery was dead and when I jumped it my ABS light was on. Dealership ended up telling me that when you let the battery die and then jump it, the abs ecu gets a surge that could fry the abs ecu.

Lessoned learned, I bought a battery tender and hook the car up on it all winter. Problem solved.

 

Battery maintainer with at least automatic up to 3.3 amps.....

 

Battery Preserver. Got it. Thanks.
