Separate names with a comma.
It could be a wheel bearing. It's not uncommon for a Prius the age of yours to develop a bad bearing. To test it, find a stretch of road where you...
Besides, the battery in a normal Prius is too small to make much difference even if you charge it to 100%. It's only equivalent to a few spoonfuls...
Low traction forces a switch to friction ABS braking, which isn't how you want your Prius to brake in routine operation. It's suboptimal. With...
Remember that displayed SOC is just a calculated estimate. There is no way to directly measure SOC like you do with gas in the tank, so the Prius...
True, but brakes aren't the only thing providing braking force on a Prius. Regenerative braking is the preferential mode, and it only works...
It would be a lot easier and cheaper to build an external charger and plug it in. But given the small battery size and limits of EV, even that...
I also like manual transmissions, but with HSD it's not possible. The HSD in the Prius is not an automatic in the normal sense - there is nothing...
This sort of trouble can be caused by a dirty mass airflow sensor, a sticking throttle plate, or fuel supply problems. Pulling the DTC codes...
Assuming the Prius is not in N, the ICE will automatically start if the speed of MG1 reaches its high limit. This is why the ICE is always in...
Do you ever clean your brakes by braking in neutral? Prius brakes get dirty and rusty from lack of use, and that will make them noisy. On an empty...
As far as the transmission is concerned, coasting is the same as gliding in D with the ICE shut down, which often happens of its own accord. The...
The two are not equivalent, if that is what you are driving at. When coasting in N, the Prius is powered up and Ready. During towing it is powered...
A true Atkinson cycle engine uses an unusual crankshaft design that achieves the four stroke cycle in a single turn of the crankshaft. This was...
No. All Prius need wheels-up towing as there is no way to disconnect the PSD from the drive wheels. Tom
"How many engineers does it take to explain Power Mode?" The answer is 15: one to hold down the OP, 14 to beat him senseless with the technical...
The Gen II Prius uses a double pole switch on the brake pedal. One pole lights the brake lights and disengages CC, the other allows the Prius to...
For owners on their first 12V battery, it's important to note that a failing 12V battery can cause no end of weird symptoms. Unlike a normal car,...
The Prius didn't have Power Mode until MY 2010, so anyone complaining in 2006 must have been prescient. Secondly, all modes have exactly the...
There is such a rule on the Gen II, although I don't recall the exact speed delta. It's listed in the manual. Tom
Only use HIDs in fixtures specifically designed for them. Otherwise you probably will blind oncoming drivers, get bad lighting, or both. Tom
