Very New - Still Learning The 2018 Avalon
 This is my first car since a 2011 Avalon, and the technology is what is taking a bit longer.  The various safety controls, e.g., blind-side monitoring, backing up guides, lane departure, etc., are new to me.  The manuals provided are very detailed, but I am one who tends to read about new things like this Avalon from cover to cover. I've had the car for three weeks, and I am definitely still learning.Updated March 2018.  Living in a small town leads to fewer miles; thus after almost 7 months of driving the Avalon, I have less than 2,800 miles on it.  There are just a couple of quirks thus far with the car.  First, when the car has not been driven for a while such as being parked overnight in the garage or all day in the parking lot at my office, when I back up and depress the brake pedal, the brakes have a slight squeak to them. It lasts for just a second or two.  The Service Advisor indicated this is not unusual for a new car and that it should disappear. We'll see. More of just a nuisance than anything else.  Second, I don't use the navigation system that much, but i have noticed that the arrow pointing to my location seems to be about 25-50 feet behind where the vehicle actually is.  For example, crossing into an intersection, I would expect the needle to be in the intersection. Instead, the needle is not quite into the intersection just yet.  The Service Advisor had no good explanation for this but offered to update the software the next time I brought the car in for service and to speak more closely with one of the technicians.  We didn't have sufficient time this visit which was just for a 6-month service.There are things I like and some things I am still getting used to. I do like the fact that the driver seat slides back when unhooking the seat belt. This makes it easier to get into and out of the vehicle.  Mileage on the highway is around 30 or so; I usually keep the freeway speed around 70.  In town, it's probably averaging around 20-22.  Living in a small town, driving is a lot of stop and go, short trips. I really like the blind-side and backup alarm systems that appear in the side mirrors.  Very convenient but I still look.  Still getting used to Entune.
