Cul-de-sacs are also a very good option as there will likely be less interference in a residential neighborhood. However, there is a higher chance of odd looks coming from the residents.

I had a hard time calibrating because of overhead wires. Finally found a field by my barn and it calibrated in short order. Seems accurate since. Have been on a long trip, 28-30 mpg, runs great. Enjoy the ride.

I did get my compass calibrated. I set the correct zone first, then pressed the check to calibrate the compass. It took five or six circles in an empty parking lot, The directions appear to be correct.
 
I am getting about 27 mpg for my 70 mile a day round trip commute which is mostly interstate highway driving through the city. Trafficwise some days are better that others. The worst mileage I have seen so far is about 23 mpg on stop and go in town driving. I am very happy with the gas mileage, this is one of the reasons I selected this particular car. I have the 3.5, 211 HP V-6 engine.

When I have the heat on there is an intermittent ticking noise that comes from somewhere in the dash. Anyone else have this issue?

There was a TSB for the '06 model's dash ticking but it was due to dash clips rubbing against the windshield. I believe that problem was fixed in the mid-06 run. Does it continue indefinitely or seem to calm down after the car has warmed up?
 
As for your '08 model, is it loud (like a rock hitting the windshield) or fairly minor? My guess is you're hearing the different components "creaking" against each other as the temperatures equalize. This is basically the same thing that was happening with the early '06s but the noise was louder due to metal rubbing against glass. I think it's just plastic on plastic in your case.

Thanks for your post.
 
The ticking continues for as long as the heat and fan are on. If I switch the fan off the ticking stops. The ticking is not very loud but can become annoying (it can be heard over the radio) and is hard to locate but it comes from various locations in the dash.

Ticking noise in o8 Impala by norbnancy

When cold (20's, 30's,40's) I get a ticking noise in the dash area that is very minor. It sounds like plastic parts expanding, probably in or around the hearer ducts. I would not allow anyone the oportunity to tear into it in the hopes of finding the cause. The ticking is not bump sensitive, but heat change. If the ticking noise is related to only the blower motor, it would occur throughout the heat range.. Since I have traveled south, it has not re-occurred. At 8000+ miles my 08 LTZ continues to be a great ride. In town driving with some hyway is currently producing 25.8 MPG. Enjoy the ride.

I used to have that in my 2000 Intrigue, it went away on it's own. Extreme cold and heat do things to a car's plastic after manufacture.
 
I took a look at an 08 LTZ at the auto show. My big disappointment was rear seat room. The new Malibu was much better. Otherwise, it's on my shopping list.

I have what I described to the service dept as a ticking in my dash, but the said they couldn't replicate it. It is not constant, but I will hear it days in a row even when the heat/air is turned off. It happens in hot and cold weather before and after the engine has heated up. The rythmn does not change. An independent ASE mechanic heard it and said it sounded like the blower fan, but another one said if it was the blower fan it would change rythmn with the speed of the fan.

Hey folks. My sister has a 2007, couldn't find one on this post board. She had a horrible accident
this weekend and the airbags failed to deploy. Do any of you know any history of Impala's having
an airbag problem? Thx. Minnesota.
