Escatly...never turn off the engine or you are sure to lose control of power steering and power breaks. No engine, no ‘power’ and a locking steering wheel.
Power steering and power brakes work just fine when the engine is turned off. They are just harder to turn or apply.
There is the possibility of the wheel locking, but generally, that's if you turn the key all the way to the point of being able to remove it - in some vehicles you even have to remove the key. It's my understanding the Pious has a button to turn it on or off. Not sure how the wheel lock function works on that type of vehicle.
The best thing to do for any vehicle is to familiarize yourself with it.
Wrong on both counts.
Power brakes still work, they are just harder to push down to engage.
Also, no manufacturer is going to manufacture a car that would lock up the steering wheel if the key was turned off while it was engaged and rolling. Imagine the lawsuits as people said they accidently turned the key off or the engine started on fire OR as in these cases, the car overrevved.
Escatly...the power you need to use the breaks with no engine power is hugh.
