polarity (red to red, black to black or car body). If the jump cables are reversed, you will destroy the inverter which will be costly.

Your 12V battery is dead. Open the trunk and remove the trunk trim on the left, for access to the battery. Observe proper jump cable...

Hi, I'm a college student and have a 2003 prius. I didnt close the door all the way last night. This morning my prius wouldnt start. I closed the door, let it sit 6 hrs and it still wont start. The remote works, the interior light comes on, the seatbelt, ABS, and engine symbol all dimly appear when I tried to start it. Will it recharge itself given more time? If not, can I jump it? If so, how? I dont have a manual.

I assume you have a 2G Prius. Remove the large black plastic cover over the radiator for access to the radiator cap. 1 mm is minimum spec.

I was told by a car repairer who did 90,000 km service that my engine water pump, not the one on recall, was leaking. I'm planning to get it fixed in Sydney later. Would you tell me where is the cap of radiator I can add coolant to?

Is it true Prius brake pads last for long time and the pad's lining could be down to 1 mm. Do you recon I should worry about replacing them as it looks still quite bit left.

...and it is possible to bleed the brakes as long as you don't allow air to enter upstream from the wheel cylinders.

I can't do that with 140 characters. Suggest you download repair manual info at techinfo.toyota.com. Classic system is different than 2G...

Hi, I was hoping you could guide me thru the process of replacing the caliper, rotor, and brakes of a 02 Prius. I have done this many times on conventional vehicles before. Is this something that has to be done by a toyota dealer? I'm very handy and do most work on my vehicles. I've seen on other posts that you need toyota tech stream software to bleed the brakes.??? Thanks for any help you can give.

It is OK. You will need to set your radio station presets and the driver's window auto up/down after the new battery is installed.

Patrick, going to replace my starter battery and note you have done so. Will order and Exide battery instead of the
Optima. Will I be OK in taking out the battery without maintaining power to the vehicle during the change out?
Will the computer functions be lost without power?

I haven't done this yet. I believe there are threads on PC, pls do a search. My guess is that you should replace the rotors at this time.

I am approaching the 200,000 mile mark on my 2007 prius, I might have to do front brakes soon. Planning to do it myself, any recommendations. looking for a thread to show the process, thanks in advance.

thx much, you have been a great source of info for diy people like myself!

No need to use a 12V source. Will need to reset your radio station presets, the driver's window auto up/down. Fuel gauge will reset.

wud it be okay still if i dont put a 12v source to keep ecu memories, what wud that do to the car, basically i am just planning to remove the old and swap with the new aux battery

ok thx for the reply

It is easier to access the 12V battery if you unbolt the brake power supply to its left. You need a source of 12V to keep the ECU memories.

Hi Patrick, I am new to this site, I have a 2007 prius like your and I am planning to change the 12v auxilliary battery with an optima ds46b24r, i found on you tube a video on how to make the swap, is there any special procedures or steps that i need to be aware of? in order to keep the settings as is on the car? glad to hear from you, thx

think all fuses have been checked (me or toyota) and they say the entire fuse block needs to be replaced because "it is not passing current"... but I don't understand how that can be when all other things like hazard lights, headlights and other electrical items work fine....
Thoughts? Would love ur two cents even if it helps me chase down another idea b4 I spend over $800+ on a fuse block... (3 of 3)

Next AM, car wouldn't start (key in cupholder)... After thinking, put key in slot & car starts/runs fine - but dash clock, int lights & radio (&"key in the cupholder" start) don't work...
checked 12v battery via MFD svc mode - it's above 12v @ ACC-ON and stays above 12v @ IG-ON...put the car in ready mode it goes to 14v (or 14.1v)... so it seems to not be the 12v battery... (2 of 3)
