    Nothing happens - that's why the gasoline engine is the primary motive force. It just means you won't have the extra umph from the electric side until it gets back in the green. Most folks who have encountered this have had it occur only on long upgrades at full throttle, but the point is that the car is NOT primarily an electric vehicle - it IS primarily a conventional internal-combustion driven car, after all....

    "It just means you won't have the extra umph from the electric side until it gets back in the green. "

    Always remembering that the Prius will not run at all if the battery is below 20%. The software is supposed to keep it above this level.

    I had the recall done on my prius in november. I filled my gas tank after I left the dealer. I immediately went from 42-43 mpg to 35- 38 mpg. I am very disappointed with this car. I wouldn't have bought this car had I known I would get such lousy mileage for the privilege of paying 6000.00
    more than a Corolla which gets about the same mileage. I would like to hear from other people who have had the recall done to reprogram the ECU.
  • I sat for 2 hours learning the computer, phone, GPS and other accessories in the IG-ON mod which drain the battery to one bar. So, I drove to the store and by the time I was back home I had all the bar's back but one. 10 minutes around trip. The manual says the car will not charge in neutral.
  • My best of 3 tank fulls is 48mpg (mostly freeway). I calculate when I fill the tank not as I am driving. The light is explained in the owners manual. Red is the IG-ON mode. One up from accessories only. To avoid this only press the button with your foot on the brake.
  • I have been trying to find out how to turn the beeping off. How did you do it? The dealer won't help. Safety reasons.
  • FYI: My 2005 Prius fell victim to N. Calif's recent flooding. Result: The electrical system, harnessing & connections were compromised & point to on-going, chronic problems due to corrosion. As a result, my insurance company just declared it a total loss.

    Granted any car that is flooded may be a total loss, but for me the bottom line is: as much as I like the (fair weather) mileage (definitely suffers in colder weather), the Hybrid technology is still vulnerable, and I won't be getting another one right away. My only hope now is that my Prius held its value & it's worth more than I owe ~ :sick:

    Happy Motoring Prius owners - it was fun while it lasted!

    I'd like to know too. Wasn't mentioned in the owner's guide. Starting to get self conscious every time I back out of a parking space. Thanks in advance.

    if you were to google:
    +prius +beeping +reverse

    i'm sure you'd find hits that address disabling this safety function.

    the issue is, is this a good thing or a bad thing?

    i presume the warning exists to make sure you are attentive to the fact that the drivetrain is engaged, perhaps because the engine is quiet and you have good cabin insulation from the engine compartment.

    if i owned one of these cars, i think i'd leave it enabled. i spend perhaps 0.1% of my driving time each day in reverse.

    anyway, if someone outside the vehicle could hear it (?) and cause them to look, that would be safer, and also might get more people to take notice of an advanced technology vehicle.

    Has anyone had success playing their iPod in a late model Prius with an FM transmitter or a car stereo interface? I have an 05 Prius that was manufactured around June 05 and an iPod nano. I can't get my FM transmitter (made by monster cable) to work.
  • Actually, I found the answer in the Prius forums right here, under the "Prius Owners: Accessories & Modifications" thread:

    No, there's a gear indicator on the dash that tells you what gear you're currently in, like many other automatic trans. cars. If I'm the one driving and not know which gear I've selected, then I've got serious problems. If the car makes it hard to tell, then *it* has issues.

    I think the beeping is there for the same reason dump trucks have them, to compensate for rear view blind spots.
    Now the Prius's rear blindspot is nowhere as bad as that of a dump truck and I want my car to be noticed for its unique styling, not because it reminds people around me of construction sites.

    Toyota did so many things right on this car, but they've really screwed up on this one reverse beeping thing. First, was leaving it on by default. Second, they made it so ridiculously convoluted to toggle it on or off. (Read the link above and you'll know what I mean). This pretty much ensures once I manage to turn it off, I would not likely turn it back on again. So the few times when I might actually want it on, such as in a crowded shopping center parking garage during Christmas shopping season, I won't have it available. *Grumble* :(
  • I am new to this forum and way of communicating so please bear with me. I have a 2002 Prius that has been in the shop numerous times. the expense of repairs has greatly offset any savings I was getting on gas. I just recently reviewed my repair record and discovered that in May/June 2004 I had strut mount front suspension replaced and electric link assembly replaced. there was no charge at that time. Then in July/Aug of 05 I was buying shock absorber and same support front suspension parts Is this right?! I just realized this and will bring to dealers attention but should this part of the car go bad so quickly and so often? I have had other problems also and am just now having to replace fuel tank and a relay and computer. A warning signal and check engine light came on so I brought car straight to dealer. The fuel tank is not covered so I am paying for this in spite of the fact that I am not convinced that anything is wrong with fuel tank. Mechanic says that is what is recommended. Obviously I am not knowledgeable about cars so I go with mechanics recs. There is less than 40,000 miles on this car.

    May I point out that the beeping is not heard on the outside, shoppers wouldn't hear anything anyway.
  • May I point out that the beeping is not heard on the outside, shoppers wouldn't hear anything anyway.

    Serious? Then it's useless on TOP of annoying.
    What was Toyota thinking? :P
  • I just finished polling three major dealers in the San Francisco area and they report customers' MPG from 28.5 to 54.5. That average out at 41.5, which is just about what all the long term tests have come out to in the major auto mags. So you're only about 8% off a very large database average. Maybe a few more pounds of air in the tires could fix that.

    If it's any consolation, your Prius is to be admired not so much for fuel mileage but the lack of emissions. Regardless of whether the Corolla can come close to your fuel mileage, it will never come even remotely close to being as clean-burning and environmentally friendly.
  • I have a 2005 Prius and like the car very much, but I am getting rid of it. On December 9th, we got a snow storm, and there were about 4-5 inches on the ground at the time. I was trying to get up a hill on a road that hadn't been plowed. When I was about 3/4 of the way up, the slip indicator icon came on, and the car would not move. There was NO power. I backed down the hill and tried again, but had the same result. As soon as the front wheels started to spin, this indicator came on, and there was absolutely NO acceleration, even with my foot to the floor. I had to abandon the car and borrow a friend's 4 wheel drive vehicle. Subsequently, I spoke to my dealer, who said the car was designed to do that as a safety measure. Toyota Corporate said the same thing- that the engines were supposed to shut down, so the electric motor wouldn't burn out. It was suggested that I get snow tires (which wouldn't help in that type of situation) or chains (totally impractical). In my mind, this is a real hazard. If I had been on a highway going up a hill and I lost all power, I'd be in real danger of getting clobbered. In my opinion, there should be a way to switch over to the gas engine for power in this kind of situation. To have no power at all is ridiculous. Has anyone had a similar experience?

    A poster last winter in New England said the same thing happened to him. He just parks his Prius in the winter and drives his SUV. I think the problem is the skid control won't let the wheels spin. I'm sure there are others that drive their Prius in the snow. Not many have complained.

    Yup, it is even more interesting for the HH and RX400H owners with AWD. The rear electric motors will stop functioning if they get too hot, which is why those vehicles are not really meant for off-roading.

    Just out of curiosity, wasn't the ICE motor still driving the wheels?

    Put snow tires on the car in the winter, and go anywhere. The OEM Goodyears are useless in any kind of snow. Get a tire/wheel package from Tire Rack or one of the others who offer same, and enjoy the car year round.

    Had those integrity tires on a Lexus I once owned. Useless. I met someone in m office who said he has a 05 leftover Prius that he put different tires on (not sure which). He said it is awesome in the snow. Tires mean everything
