Prius (Gen 3) :: Power Modes Display Car Putting Torque Through Drivetrain
Aug 3, 2014
- handbrake = parking brake foot thing - the thing that applies rear wheel brakes when stationary;
- manual = stick-shift etc.
- service brake = normal foot brake/big middle pedal
Driving scenario: Short pauses, quick lights etc - no problem, the car is held on the normal brake and the drive knows I have my foot on the brake so shuts all drive down.
Discussion point here - at lights, longer pause in heavy traffic, level/railway crossing etc. The sort of pause where you want to take your feet off the pedals and wait.
With a manual I would put the car in neutral, apply the handbrake and wait. Then when moving again, car into gear, hand brake off balanced with clutch bite and accelerator.
The car was left in drive all the time & knew if the handbrake was applied not to try and engage forward torque/ride clutches etc. Never needed neutral on the Audi multitronic.
With Prius III when I pull up, if I leave the car in drive and apply the handbrake, then take my foot off the service brake the power modes display shows the car putting torque through the drive train - i.e. battery->motor->wheels & you can feel it pulling slightly in creep mode against the handbrake.

I tried to find this by searching, because I know it has been addressed before, but I just can't find the answer. In the Multi Function Display, there are 2 modes. They are indicated in the upper right hand corner of the display screen, as a small "1" and "2". I am on "2" now and want to get back to "1". I can't for the life of me remember how it's done. If you know the reason for these modes as well I would really like to know.

During my 35 years of experience as a production line and service engineer in the aerospace industry, it was my job to determine the least expensive and easiest foolproof way to perform any production and service operation.
Many readers here have related their experience with the oil filter housing and their difficulty with its removal and reinstallation with the need of a torque wrench to correctly tighten it. Most all technical tightening of screw systems have gone to the "angular torque method," as it is more accurate than the standard torque wrench.

I recently got a prius plugin. In last couple of weeks I have noticed that when I am EV mode and speed crosses over 65, my HV mode kicks in. But I can see the EV mode running in parallel with HV until the EV runs out. During this point, I see both the EV miles and HV miles piling up and it seems like doubling the miles in EV & HV. I saw this four or five times in the last two weeks.

my 2007 Prius has been sounding a bit under the weather lately. There is a grinding scratching noise. This happens in either EV or HV modes and is most noticeable when bearing right. The tires are on their last treads, and a bit scalloped but that seems to me to be a different sound.

What are the selection input for these? I have seen them go back and forward on its own. I have also been told that there is an in-cabin humidity sensor but have seen no documentation on it. Does that switch between fresh and recirculate?

Is it "safe" (meaning for the car) to change driving modes while driving? I understand that all it really does is change the way the throttle pedal works but just want to make sure that I don't have to be stopped to change modes.

So after figuring out that my 08 is in power mode and will not automatically go back to econo mode ... how can I manually change modes on a GEN II? I know there is a way as I got it in that mode and can't get it out!

Eco/Normal/Sport S/S+ Mode... the literature doesnt say much except it changes throttle response and power output. For the Sport modes it says that "The rear-wheel drive IS 350 F SPORT's Sport S+ mode also tightens the suspension..." Are the shocks somehow adjustable, or is this just marketing BS?

I have 70,000 miles and this weird rattling somewhere in front, probably drivetrain, only audible at 60-70 mph, medium load, so no pinging. worse on high speed right turns, like highway entrance, and in this circumstance audible at about 50mph.
I recently did cleaning of intake manifold, EGR pipe, and TB and an oil change and no change. The noise is totally absent in city/suburb style of driving with speeds up to 50mph. what could that be? It's clearly getting worse. could it be connected to the CV clicking noise i have at slow speeds?
I searched some more and there are few threads about noise that sounds like pinging, but doesn't behave like pinging. no resolution except for the standard advice about higher octanes and gas additives:
-Engine ping under load
-Higher octane gas for fuel pinging
-Engine pinging

Whenever I take off from a stop or slow to a stop, there's a clunk in the drivetrain. It feels like a bit of play before the drivetrain engages and when it releases...torque converter maybe? Taking to the tranny shop soon...

Recently purchased my first Prius, it's the v wagon.
When accelerating from a stopped position in eco mode there's a relatively severe drivetrain shutter/vibration for a a short period of time until I back off the throttle, almost feels like a clutch slipping with added vibration.
It's probably a normal noise produced by this style transmission, just looking to verify if this is true so I can stop worrying about it.

Aside from spending $ to have the polarity reversed on the HVAC display, is there anything be done to darken the display letters and numerals? In the daylight this thing is unreadable. Very poor design by Toyota. Any little tricks that I don't know about?

Not the usual. I stopped on my way home to get gas tonight when the gauge was showing one pip. Naturally it wasn't low, but I'm used to that.
The odd thing is that after I got in the car and turned it back on the gauge stayed at one pip and the fuel display on the multi-function display didn't reset.

My 2010 Prius is 1.5 years old now and I had my first problem this morning. The last time I drove it was Wednesday so it has been less than a week. When I tried to start it this morning the dash lit up but was very weak. You could tell the battery was very low so I turned everything off. I hooked up my boat battery to the underhood terminal and it started right up. I looked around and all the interior lights were off. The other thing that happened is the right half of my display won't light now. No Clock or power gauge. I do, however, have speedometer and gas gauge. I didn't even loose my radio presets. The battery was weak but not dead.

I was playing with the settings on the Display Audio/Setup/Vehicle settings.
I turned the "Key System with Elec. Key" setting to off.
Now I cannot turn the Power on in the car. I can unlock/lock the car using the buttons on the key FOB.
But when I press the Power button with my foot on the brake, all I get is the red "no key" security indicator on the display.

Finally received my Prius 4 a few days ago.. I cannot find the way to get the power mode curve to display on the screen. How to do this? I have been able to get the curve on the HUD but not on the screen next to the speedometer. I do get a bar indicator showing the modes stacked up inside the bar but no curve display.

What is EXACTLY going on when the Prius is put into B mode ?

I have a 2008 Prius. In 2009, I got into a collision, and the car required extensive body work. This week, I took my car to the mechanic to repair the air conditioning system - only warm air was blowing out. According to my mechanic, the compressor went out because the auto body shop put in the wrong oil in the air conditioning system and re-installed the fans backwards. I got my car back today, and the air conditioning works really great!
However, my family spoke to their mechanic (different person from my mechanic), and he indicated that used compressors are dangerous due to the high likelihood that contaminants will be leaked. This sounds completely ludicrous to me. My mechanic said that the other mechanic's concerns are unfounded.

Is it very bad to Power off before putting the car into Park? It seems to go into Park upon hitting the Power button automatically.

After getting on the highway, the red triangle of death, the amber ABS and the VSC lights came on, and little exclamation point came on on millage/audio screen, while battery power went down from high blue to one blue bar. Pulled car over to parking lot, and put in park. After putting it in park, the car would not go out of neutral, but the power still worked.
