A few items the average DIY misses on preping a vehicle for winter.Clean the top of the battrey yes clean the cables but alos clean the top to prevent a parastic voltage drain this is worse on newer vehiclesClean the throttle paying close attention to where the palte meets the bottom of the bore and if you drive a lot of stop and go I would also check the IAC and clean if necessary.Check the wipoer blades I use winter blades but they have some problems so it is a personal choice.Double check that you have the correct tire pressure I just found out with one of my vehicles that the max pressure is 44# I have been running 32# diffintely a improvement on the ride and handling if in doubt what to put in your tires check with a local expert at a tire store. Dont count on the recommend tire pressure for your vehicle being correct from the manafacturer
