Plan your Nissan's pre-winter service for October. Indianapolis-area averages put the first freeze here in Central Indiana in late October and the first measurable snow in mid to late November, so a visit booked in October is ahead of both with room to spare.
Start with the battery, tire pressure and tread, and wiper blades. Summer heat or overcharging can weaken a battery before cold weather exposes the problem, and tires can lose pressure as temperatures fall. You can schedule service online.
