Toyota Prius Basic Care & Maintenance

    Is it possible to fit three forward facing child car seats in the back row. I have the narrower car seats that are 17" wide so am wondering if there is at least 51" between the doors?

    The best bet is to take your 3 seats to the dealer and see if you can buckle all 3 in the back seat.

    Can someone tell me when I should do an oil change on a new car? I have 5000 miles at this point. Thanks,

    my 2006 Prius has a 'maintenence required' light that comes on every 5000 miles. I use it for oil changes and tire rotations.

    It is is your maintenance booklet, or online at, then at the bottom of the page see "owner". Then go to "service maintenance guide", and download. Every 6mos or 5,000mi. when using "regular" oil. 0w-20 SYNTHETIC oil change intervals are doubled to 10K mi, 12mos. as per Toyota maintenance booklet ( "service maintenance guide" page 56)

    What's the deal with taking a Prius thru the carwash? I have a 2010 and haven't had a problem with doing this... thanks.

    There is nothing at all to worry about. Drive on!
  • Does the new 2010 Prius now use 0W - 20 SYNTHETIC ?? My 2007 uses 5W - 30 synthetic oil !!

    I was replying to a question about a model year 2010 Prius. Yours, you say, is an '07, as is mine. On the engine oil cap, as well as in the owner's manual, the recommendation for 5w-30 oil is made.
  • Toyota sent me a new maintenance book and letter explaining that the '10 Prius was certified for 10K miles between oil changes if using 0W-20 synthetic oil. I've now exceeded 5K miles since my last oil change and the maintenance banner is on every time I start the car. I don't intend on taking my car in for another 5K miles, is there a way to clear the banner or ask my dealer to reconfigure it for every 10K instead of 5K?

    So, did you have an "old" maintenance book that spelled out 5K mi oil change intervals? Was you car one of the early '10s sold soon after the May '09 introduction? The Toyota website reads 10K oil change intervals when using 0w-20
    oil. The car can use "regular" oil, but still have the "used-to" 5K mi change interval.
    I suppose the 10K mi interval can be selected, or programmed into the reminder system either thru your input, or the reprogramming by the dealer service personnel. The service advisor does mine on my '07. ( I change my own oil. )
  • I bought my Prius in early August '09, the original manual did say 5K for oil and it did not come with the USB/iPod interface. I don't recall seeing anywhere in my docs that you can use regular oil.
  • 2007 Prius, 30,000 mile service - dealer informed me that my starter battery was fine and had a 75% charge, despite several recent incidents where I needed to jump-start my vehicle. Dealer service technician told me that the starter battery is made from gel, rather than lead acid, due to proximity of the battery to the passenger compartment and toxicity of a lead acid battery. Cost of a replacement battery is $300, compared to standard off-the-shelf batteries at one-sixth the cost. Despite passing the dealership test, two days later, I had to jump-start my starter battery again.

    In past vehicles, I always replaced my lead-acid starter batteries every three years. I operate my vehicles at night and under cold weather conditions. I also always carry a back-up battery to jump start my vehicles.

    What is the lifespan of the Prius starter battery?

    What is the composition of the battery that makes it cost so much to replace?

    When should the starter battery be replaced?

    Why are service technicians unable to detect a weak battery?
  • whitey9whitey9 Posts: 138
    Possibly your car has a current draw. This would bleed down the batt and cause a no-start condition. It is really just a small batt the size of a riding lawn mower, or motorcycle batt. As for $300, well that sounds a bit high, but I have no experience with replacing mine yet. Anyway, if they say the batt tests "good" but you still have to jump start, and you are sure the lights are off/doors closed, etc. then the batt MUST be at least weak to give you the no-start situation. Replace the batt as they recommend, and then let them "splain" it when the car fails to start like it did BEFORE you had the batt replaced. I'll bet you get a whopper of a story. ( sunspots, ghosts, oil spills ) HA! ;)
  • Since moving to day shift a few weeks ago, I have no starter battery problems. Also, I have installed an electric inverter into my cigarette lighter that charges my emergency jump-start battery while I drive. Therefore, even if my starter battery fails to respond, my jumper is fully-charged. Without night drain with headlights operating and heater often required, the starter battery does not seem to fail. Furthermore, I am driving more in summer to reach trailheads for hikes up the 14,000 foot peaks in our area. I hiked 15 during the past 6 weeks, with a few more in the plan for this week. More frequent driving seems to improve the charge on the starter battery. During most of the year, I let the Prius sit in the garage and commute 16 miles a day by bicycle. With the savings, I can afford to pay $300 every few years for a new starter battery. :shades:

    I see that you said driving with the lights on, running the air or the heater drains the battery. I thought it charged everytime you brake? Also, I run with my lights on every day because I want to make sure I am seen. Should I not do that? Mine is a 2008 and I can't imagine paying 300.00 for the battery not to mention what I will be charged for the dealer to put it in. Scary! How long is the battery supposed to last?

    Thank you.
  • I've been having starter battery problems myself and discovered that the power related to the lighting and cigarette lighter ports as well as the CLA port in the console are directly tied to the starter battery. this battery charges like a traditional 12v battery not tied to the braking or other mechanisms used to charge the NiMH batteries used by the engine.
    Word of wisdom, dont charge multiple devices out of the CLA's or even leave your chargers plugged in as they draw amps at all times from the 12v. it costs $300 from the dealer to replace the 12v too as its special
  • Point of order: Good advise as to removal of battery charging cords. I find that the little 12V battery is, pound for pound, an amazing battery with likewise amazing longevity. 8yrs and going strong. What a powerhouse battery. F.Y.I... I suggest checking around for this special battery. It does cost more than a usual std battery but I found it at my local dealer for $179.00 approx. My '04 Prius has over 135,000 miles and one heck of a reliable hybrid. Winters here in N.W. Indiana are extreem and the Prius has proven to be worthy of the challange.
  • DO NOT leave your key hidden in your Prius car. It will continue to talk to your computer back and forth and drain your battery.
  • This must be pertaining only to the "Smart Key" fob cuzz my standard key fob is going on 8 1/2 yrs (original batterys) with no problems. I leave it in every night (in the garage of course) 136 K miles and lovin it!!
