Both good questions.
A) Cruise: It's a personal choice. I find that using my own inputs that get very very slightly better fuel economy by using pulse and glide. On a very long trip cruise is very helpful though. You mentioned putting it on at 35 mph. I definitely wouldn't do this because the HSD is set up so that when you let off the pedal at 41 mph and less the gas engine actually turns off and burns no fuel whatsoever. This is a huge saving. If you set it at 35 mph as soon as it sensed 34.8 mpg it would shoot some gas into the system. You might want to up your setting to say 45 mph and higher.
B) There was definitely an issue with the Traction Ctl System and heavy snow/ice on the earliest Prius'. If you were at a dead stop in deep snow or on ice the TCS would brake the wheels to keep you from spinning out...but then you wouldn't go anywhere.
To address this issue in 2005, beginning with the 2006 models, Toyota modified the TCS to allow some spinning of the wheels to allow the driver to spin and rock themselves out of deep snow.
Pose your question also on PriusChat or GreenHybrid to drivers who live in Canada and the Rockies. Most will tell you it's not a problem.

I own & operate an '04 Prius with 59,000 miles. Just put my 1st set of replacement tires on and am still on my original set of brakes (this is a 1st). Most of all my cars I've ever owned needed brake pads and/or rotors turned at about 32-36 thousand miles. This has been a pleasant surprise. Now.. As to wheel slip. I have noticed after three winters and especially this one with it's heavy snowfall, a pattern unique to the hybrid Prius. There is a completely different feel of the wheel traction with the Prius. Actually, it's more of a lack of it due to the electric mode I think. With three years under my belt and alot of trust in this amazing car I think that its best put by saying this car is rewriting the way a car feels, handles, and reacts to the outside world. One last point: I have come to the surprised amazement that the Prius tracks quite well in heavy snow and it seems to pull even a bit better than many other frontwheel drive cars I've owned. The only noticable disappointment I've had with my Prius is the considerable drop in MPG's when it's severly cold (say in the teens and less). Gas engine runs considerably more to get heat to the heater my guess. Oh! and cruise sure helps to get best MPG's.

A friend to whom I've sold two Prius' uses his for his mobile office. 135,000 mi in exactly 3 years.
He too is still on his original set of brakes!!!
Tread lightly and this amazing car will continue to surprise and surprise.

Thanks to everyone for their input. So I took a Prius out today for a couple hours. I must be misunderstanding something about the motor vs the engine at slow speeds. I thought that the engine wouldn't come on until you got up to 41 mph unless: 1. you have to warm the catalytic converter up when you first start, 2. you have the A/C or the heater on anything but the lowest settings, or 3. you have to accelerate hard to get up to speed. But even with the radio and the air system turned off, I couldn't get past 11 mph without the engine kicking in. Outside temp was 47 F. I got onto a side road in a neighborhood where the road was flat and there was no traffic to p*** off, but I couldn't get to 12 on the motor alone. Am I misunderstanding how it should work, or do you have to accelerate on a downhill, or what?

The ICE will come on when the computer wants it to. That is to say don't worry about it really. The 41 mph trigger is where the ICE will turn off when you the operator tell it to turn off. Sounds confusing?
At a cold start the computer will tell the ICE what to do.
After being warmed up fully, 10-15 min, then you have more control over the ICE up to 41 mph. Up to this point if you don't give the GO pedal much pressure you'll crawl forward on the e-motor only such as in slow heavy traffic or in a mall parking lot.
When you put your foot into it the ICE will take over and run almost all the time. It's very dependent on your foot. Release the pressure, under 41 mph, and the ICE will turn off.
Don't worry about crawling up to 40 mph from a standing start, it takes too long and doesn't work. Just accelerate up to normal speed and then let off the pedal if conditions warrant it. To tell you the truth, no one, well almost no one, ever get off from a standing stop faster than I do. I just gun it get up to the speed of traffic and glide/coast as much as possible. ( 48 mpg lifetime average over 40000 mi - mostly highway at 62 mph )

I hear that Toyota is beginning to finally offer some deals on the Prius models due to slowing sales. Indeed, I have seen a few lease plans that potentially( I have NEVER liked Toyota sales practices at all ) look attractive, and I'm considering looking into the car after dismissing it due to ridiculous prices in the past. In speaking to a friend who recently drove a Prius at night, she commented about a green reflection on the windshield at night that she found dangerous. Has anyone else experienced this , and if so, can you comment?

The green reflection is from the speedometer. It can be almost eliminated with a small hood over the meter readout. The light is projected up, and reflected to horizontal by a mirror. In other words, when you look at the readout, you're actually looking at a mirror. This system has some spillover of light, and a small hood over the speedometer readout will stop most of it from impacting and reflecting on the windshield. Keeping the inside of the windshield clean helps too.
Slowing sales? Feb sales were an all time record for Prius, I'm told. Toyota has ramped up delivery to the US dealers. Now that they have lots of cars, they have to use "standard sales practices" for cars, instead of "if you want it, make an offer, it's the only one we'll have this month" as happened in the past few years.
There is some speculation Toyota is using up parts for the current model, getting ready for the next generation Prius. It's possible, but there is no real evidence, although there have been some comments from Toyota people on how "well" the new design is coming along.

Yes sales are booming now because the initial hesitancy has passed and the vehicle has proven itself after 6 years here. Toyota doubled production and shipment to the US so every dealer has what would be 'normal' inventory.
The deals are attractive especially the financing.
Regarding the green reflection on the window at night... there has always been a dimmer on the dash light 'roller'. All the way UP it clicks into place and is very bright. Roll it DOWN slightly past the click and the screen goes to a dark background with very little reflection on the windshield.
#7111 of 7508 Battery Replacement

My Son's Prius 2001 has over 80,000 miles & he is concerned about it.
Has ANYONE had to replace their batterry near 1000,000 iles?

I'd be surprised if anyone has 1 million miles on a Prius yet. The most I heard about was a taxi driver who put about 250,000 miles on it with the original battery.
