    I just purchased a 2007 Prius with 150,000 miles, the used car dealer told it had two previous owners. Per the Toyo owner website it shows consistent maintenance through 113,000 miles at dealerships across the country (its had a busy life). I drove it home 60 miles and it ran fine, I reset the MPG before I left and got 54 MPG with driving speeds as high as 69 MPH

    Maintenance that I know has been done includes:
    All recalls
    85,000 Battery Coolant pump replaced
    106,000 belt replaced
    112,000 spark plugs and front brake pads

    I cannot tell how old the 12V battery is, its a Toyo, if I remove it will it have a date code? and can i decipher it? What is the consensus about replacement? I don't want it to strand my daughter.

    I don't know if the differential or transmission oil has ever been replaced the manual just says to inspect it. Thoughts?

    It came with a single SKS key fob that is very damaged but works, whats the best way to get another and have it programmed? Can I buy just the case for the fob? The buttons are broken and the internal switches are exposed.

    The oil was changed by the dealer with 5W-30, thoughts on oil? Two of my other Toyota's use 0-20 with 10K oil changes. Should I stick with 5W-30 conventional and 5K changes

    Any other advice about what should be checked or replaced? I bought this for my daughter and I don't want it to strand her!

    Call around to a few locksmiths. One or more of them probably can supply a replacement case (only) for the working FOB and get a second one for about half what a dealer would charge.

    If the battery looks at all like it has some age on it, I would put in a new one; cheap insurance.
    The charging voltage should be checked at that time.

    I checked the voltage today, sitting for 24 hours:
    12.4 volts static
    11.6 volts with headlights on
    13.9 volts charging

    My concern is that I know checking the voltage is not 100% proof of a good battery. I thought about removing it and taking it to NAPA for testing? thoughts?

    The drop with headlights on is excessive. Plan on a new 12v battery soon.

    Do the Transmission fluid drain and refill now and again in 60k miles. It should be about $100 at a dealer with Toyota type WS ATF.

    The coolant (both loops - Engine and Inverter} should have been changed at 100k miles (the Inverter coolant MAY have been refreshed when the Injverter pump was replaced, but sometimes not). Change both again in 50k miles. Use only Toyota Super Long Life (pink) AF.

    Keep a close eye on oil usage as many Prii start to use oil after 100k miles.

    All sound advice above. Most def get a new 12V.

    In the urgent preventative category, I'd add inspect/clean the HV battery fan and replace the cabin air and engine air filter.

    If you're looking for other ideas that may not be quite so urgent, you could take a look at this post where I documented what I've done to my used 2008 in the Fall. I was also sending it off with my daughter to school.

    Here's a list of tips I covered with her - she wasn't interested in reading about her car, she just wanted the keys.

    For the spare key, we went with the cheapo Ovni version (ovnisf Keys - Best Quality Aftermarket Remotes FOBs Keys Clickers) - only $35 and it works.
    I used 5w30 synthetic and will shoot for 7K oil changes.

    RTFM - Read the Manual
    Don't ever lose the key - there is no spare (we've since gotten one)
    If you get a (!) light, it means the tires are low
    Always check your gear before moving - easy to confuse R and D
    Always press the "P" button when parking, then hit the Power button
    Don't ever run out of gas - can cause damage to hybrid system
    If the dash lights ever go haywire - probably needs a new 12v battery
    If the keyfob doesn't open the doors and the Start doesn't work right, probably needs a new 12v battery
    Realize that when you are in a parking lot going slowly, people can't hear your car
    If towed, don't let them tow it with all four wheels on the ground - front wheels must be up or flat-bed
    If you can't see the dash lights when your lights are on, turn up the brightness
    If you hear a buzz when listening to the iPod, unplug the power to the iPod
    No need to use "B" mode - it's for long downhills only and has no cruise control
    If the car won't turn off, try holding the Power button down for 5 seconds
    Review the touchscreen functions
    Review the keyfob functions
    Demonstrate and try the spare tire and jack
    Don't block the rear vent
    Avoid driving in snow due to light weight and low traction of Prius (no snow tires on ours)

    Gas up when you see 2 bars or less - don't run out of gas
    Don't try to jump the battery...just call AAA and have it towed home or to the shop.

    Thanks for all the help, replaced the cabin air filter today, it was bad! Air filter is new, where do I find the HV cooling fan?

    As for the battery, what's the best? I saw lots of old threads about Optima, is there a consensus aborts what's best?

    I've read hit-and-miss about Optima. I went with the OEM from Toyota. It was about the same price when I got it on sale, but I'd still probably spend the extra $20-30 for it (uninstalled, of course). Search this site for HV battery fan. There are one or more DIY posts about doing it. It's simple and won't take you more than an hour even if you take your time.

    I don't have a dealer close by, a local oil change place uses Wolf's Head "Super Universal" I checked it out online and it meets the WS spec, the cost of a change is only $70. Another shop in town wants $175 to use Toyota WS. Does anyone have anything good our bad to say about Wolf's Head?

    ONLY $70 FOR AN OIL CHANGE ????

    Where exactly are you located. Maybe WA doesn't stand for Washington state ?

    I would stick to WS. You can get it at any Toyota dealer and on line.

    I would use WS ATF and DIY...you can get from eBay or Amazon for a bit more if you can't get to a dealer.

    There are several DIY posts and videos explaining this activity. It's almost as simple as an oil change. You may need a couple of sockets/socket drives that you may not have already, some vinyl tubing, a funnel, a jack, some ramps and/or jackstands, a drain pan, some waste containers, a torque wrench and some rags.

    I followed the directions and removed the HV blower it was fairly clean, a light coating of grim dust on the blades. I cleaned it with a toothbrush and q-tip and then bench tested it and it worked well. Used my compressor to clean the little filters on the intake ducting. No pet hair and very little dust.

    Removed the battery and had it tested at an auto store. It tested good but based on the date stamp it was made in January 2007 so it's original to the car. I just ordered an Optima from Amazon $147 with free shipping.

    You should have gotten the 12V battery from Toyota, b/c the larger size (7Amp hr more).
    Toyota True Start (for SKS) is 45AmpHr, 7 year warranty (0-24 months 100% Toyota pays, 25-48 months 50% proration, 49-84 month 25% proration)
    Optima Yellow Top for Prius is 38AmpHr, 3 year straight warranty (no proration).

    You should buy a NEW SKS key fob, not used. Otherwise to get used sks fob functioning (sks part that is), dealer needs to reset sks ECU so it will relearn existing and used sks fob. SKS car can learn a used sks fob, but sks functionality of used sks fob wil not work due to ECU needing to be reset. Post #6 explains it all. key replacement questions | PriusChat

    I would use NOTHING but Toyota ATF-WS transaxle fluid. Something else MAY be ok, but do you want to experiment?

    I'd also be inclined to stay with stock battery. 12.4 volt is what ours reads, if the car's sat for 2 or 3 days. Think you'll be ok for a bit, but all considered you should be prepping for a swap. Get a fresh OEM, hook up to a smart charger (low amperage, around 3-4) and let it run till its happy. Clean the cable clamps before installing.

    I just submitted a cancellation to Amazon for the battery, I should find out later today if they will be able to cancel in time. It's not the warranty I am looking for in a battery, it's long life and not leaving my child stranded. The Optima is getting good reviews from Amazon Prii owners. However, I know I can't go wrong with a factory part even if it is way more expensive! While I am there I'll pickup some WS. It is interesting to note that the manual says Toyota WS or equivalent. What I found on the Internet is that the viscosity of The WS made for Toyota by Exxon is lower at 100C than the equivalents!

    Shop around if you can. I was able to find a dealer in ATL that would sell me their battery using the 20% off coupon that they sent in an email flyer. It was supposed to be limited to in-shop services, but the Parts guy let me use it anyway. Took the price down to about $150 before core fee. Of course there are about 10 Toyota dealers in the metro ATL area so competition is tough.

    Oh, and I'd still take the advice above and top it off with the charger before installing it.

    While you're at the dealer, pick up some SLLC Coolant and some oil plug gaskets for future oil changes.

    The brand/type of the battery does not matter that much. What's important is to have the battery charged fully before installation and keep it that way during use.
    Here is what I recommend ( comes from Electrical Engineer):

    1. Charge the battery with trickle-charger or whatever charger you have to 100% before installing . Fully charged gel battery is 12.8+ volt at no load, some time after charge
    2. Replace cabin lights and light in trunk and lights at the bottom of doors with LED. This will decrease the drain by 10x when you (or mechanic during the maintenance) leave the door or trunk open for long time when the car is OFF.
    3. At least every 3 month check the voltage of the battery and trickle-charge
    4. Learn ( and teach every driver) the difference between "Ready" and "Acc" modes. In "Ready" the 12-v battery is charged by inverter even if the gas motor is not running. In "Acc" everything is fed by 12-V battery and its not being charged.
    5. Turn the headlights OFF before shutting down the car. Auto-off will turn them off in 30 sec after you turn off the car, but all that time they will be fed by battery.
    6. If you have SKS, keep the fob at least 30 ft away from the car when the car is "OFF"
    7. Maybe I forgot something?

    Thanks,
    - Alex

    Alex,

    Tell me more about keeping 30' away with the key fob, this car does have the SKS feature. Does this drawn down the battery in both the car and the fob and how serious is it?
