Toyota - Prius :: 2010 - Dashboard Lights Up But Ready Light Doesn't Come On
Jan 22, 2014
Since I purchased my 2010 Prius new, it often won't start. As instructed, I press the brake, push the power button for a few seconds, and hope that the ready light will come on. Typically, the dashboard lights up but the ready light doesn't come on. It can take ten minutes or more to get the car started. This happens when the car is cold, or has been sitting for a while, or randomly at other times. The Toyota service department will only address the problem if they can replicate it. I've left it at the service department for a couple of days until they experienced the problem. They reset a computer component which worked for three months. Now the issue is happening again and I'm back to trying to convince Toyota that it's a problem.

I noticed on the way home the "ready" light was on the whole time. I've never noticed it staying on before but maybe just didn't pay attention to it. Is it supposed to be on continuously? What exactly is it for?

This started about 2 months ago. About 10% of the time when I depress the brake and press the Power button, all the dash lights come on except the Ready light (it acts as if I pressed the Power button twice without my foot on the brake). When I depress the brake a second time and press Power button again, the Ready light will still NOT come on. I have to press Power button with foot off the brake to shut off the dash lights (the car is effectively off) and then when I press Power button with foot on brake a second time, the Ready light will come on. I effectively have to try to start the car twice. I also noticed that the interior lights are dimmer when I open the driver's door until it goes through it's normal noisy gyration (something to do with the brakes?). I'm thinking that the 12-volt battery is starting to fail. Does my Gen III 2010 Prius have a diagnostic tool to check the battery?

The power outlet under the dashboard doesn't work. The one in the console does work. Question? Where are the power outlet fuses located and how many?

I recently changed out my 2006 blown gas engine with a great running 2008 engine and also replaced the hybrid battery. After connecting everything, my car won't start. All the lights come on except for the ready light. Does something have to be reset?

The 2010 Prius in our garage would not start today. I tried jump starting it with the 12 volt in our van, but the light on our smart jumper cables would not light up on the Prius side even when I switched them around. I followed the manual's five minutes revving and such, but the ready light does not come on in the Prius. There is enough power for the inside lights to come on, but they are dimmed. I'm thinking we left the lights on in the back seat dome area based on what my daughter told me. The car has not been driven for about 65 hours.

Just bought a 2011 Prius and I love it. When I push the power button to turn it on, the ESC light comes on along with the caution triangle light for about 3 seconds then both go off and the "ready" light comes on. is this a normal occurrence?

I've got a 2010 Prius w/ NAV. Yesterday morning, my Prius would not start. When I pressed on the brake, the green "Ready" button would not light up. When I pressed the start button, the NAV screen came on as did some of the dash lights, but the car engine itself was not on. When I hit the start button again, I had a yellow triangle on the left side of my screen that continued to blink.
From reviewing the forum, I believe that the issue is the 12V aux battery. I was able to get my car into maintenance mode, and the 12V battery was reading 8.6V; however, this was after my car had sat in the garage for 10 or so hours. However, by going into maintenance mode, I was again able to get my car to start. This morning, I drove my car to work (about a 15-20 minute drive). After I got to the office, I turned the car off and got back into maintenance mode. This time, it was reading 11.6V on the battery.
Am I correct that this is most likely an issue w/ the 12V battery going bad on me? I purchased my Prius in July 2010, and I have never changed the battery. It sounds like the "typical" lifespan for the battery is right around 4 years, so this seems to make sense.

I have a 2010 Prius that I bought in January. No problems until this morning. Here is the situation...
I get in my car, step on the brake, mash the start button and nothing. The green ready light does not come on, no key detected does not come on, nothing. However, if I take my FOB, and place it by the start button, the ready light will come on and it will start.
I thought it could be a battery issue but, this happens with both FOBs...

I most recently drove my 2006 Prius around on Saturday Feb. 1, with no problems at all. I went out of town for a couple of days, and returned this afternoon to a car that will not start. I stepped on the brake, pushed Power, and things lit up, the "Ready" light flashed a few times but then went off. Power button light stayed orange.
Several warning lights on dash stayed on (!)/ABS/VSC/traction control, and a message came on the screen saying something about a problem with "P" parking, and that it should be parked level and the parking brake applied. It is sitting level with the parking brake applied already. Also, the door ajar warning light and beep start as soon as you open the car door to get in.
I'm thinking from what I've read that my 12v battery has died/is dying. I'm the original owner, bought car in March 2006, and it has just under 61,000 miles on it.

About once a week our 2011 Prius will start, but the "Ready" indicator does not come on and the car cannot be shifted into drive. Once this happens it takes several attempts, turning the car on/off, until it finally comes on "Ready." I cannot create the problem, but it may stem from pushing the start button before the brake is fully depressed.
Last night it took more than 5 minutes to get it going. I "reset" the car by exiting, locking, and re entering the car. Then it worked, that procedure caused it to work.

We have owned our Prius since 2011, with no problems, other than the need to replace the 12 volt battery this past fall. Recently the dashboard display was totally dark. Nothing showed- altho the car would run. But then- it wouldn't stop. We called the local dealer who ran thru several options- and finally the car turned off after holding the power button for several seconds. We took it in- and were told it was the KAAR security system, which should be removed. We had that done.

I have a 2007 Toyota Camry with electrical problems that started showing up recently. One day the check battery light turned on and about 15 minutes later the AC would lose power intermittently. After parking the vehicle that day I tried to start up and only heard a rapid clicking sound. I exchanged the battery since it was still under warranty and everything seemed to work fine for one whole day. The next day the battery light turned on again, followed by the ABS warning light, and then the airbag warning light. Within about 5 minutes the dashboard back light started flickering and other warning lights started lighting up randomly. Within a minute of that the car shutoff and would not start back up again.

I just drove my 2 year old prius during the snowstorm for the first time. While parked, I turned the car on, headlights on, and tried to move the car. The gas engine already shut down during warm-up. Car was stuck in snow. I had to move back and forth on electrical only a few times before getting out.
Here is the question. After a second or third try in reverse, dashboard lights suddenly went totally dark, and would not turn on until headlights were off. I could not drive like that at night, so I stopped and googled it on my cell. Turns out the dimmer was all the way off.
But how???? I did not touch it. The car started just fine, everything working. Only after a few attempts to get of of the snow the dash went out? Is there something wrong with the electrical circuit? I did try to move the car very gently, without flooring the pedal.

Gen III, 2010 Prius III ... There is a flashing yellow triangle, dashboard lights up, but won't start. The dome lights won't turn off, in any position.
Drove it last night and drive it regularly, daily. I came out to the driver side door being not fully closed. What's going on?

I have a 2010 Prius Hybrid and lately, on an intermittent basis, I will press the brake pedal and push the start button and the dashboard lights up as normal but when I go to put it in gear nothing happens. The last time it happened the fan was running and I couldn't turn it off. It's like the car is all set to go but all the interior controls don't function. I then shut it off and restart it and everything works.

I've recently noticed that sometimes the EV light doesn't come on, even when I'm below the ICE line and I've released the gas pedal and pressed it down slightly again.

When I backed up yesterday, some dash symbols showed up. After turning off the car, I am not able to get it in Ready Mode. Only solution so far: to disconnect the 12V battery and wait approx. 2-3 minutes. After that, the lights are off. The 12v battery does also indicates normal voltage. IG-OFF: 12.7V IG-ON 12.2 ... Unfortunately I cannot get the trouble codes with my scan tool ...

I recently (two weeks ago, actually) bought a one owner clean car fax 2007 Prius with 125k after totaling my 2004 - I got the 04 cheap enough that the payout covered the new one. The car ran perfectly; quiet, no whining or grinding noises, etc. About a week ago, the check engine light came on. The next day, I got in it to drive to school. I get to the middle of my campus and it starts to lag (very similar to the way my 04 did when it needed a new hybrid battery cell). I pull over and turn the car off and back on since that used to be what would get me home in the 04.
Every single warning light came on, including the master one. My "BRAKE" warning light is also on even though the e-brake is not. The car would not show "ready" and would go into park, but if I tried to shift into anything else, it would pop into neutral. (The dash as of now is shown below.) This is not user-error. I have driven a 2nd gen Prius before, I know about pressing the brake down when you start it. The garage I had to get it towed to has no idea what to do with it and each Toyota dealership I called told me that they hadn't heard of before.
I bought a new 12V and the garage said it didn't make a difference, but I'm not entirely convinced they even tried it.
