Prius v in Automatic Car Wash

While car is in neutral the battery will not charge. I run mine through a car wash just like you and have done so for years with no problems. Before you start through the car wash turn everything off that will cause battery drain, lights, radio, heater, air conditioner, etc. And you will have no problems. You are only in the car wash a couple of minutes with the car running in neutral. That's nothing.

 

You can let it run as long as you want in Park. The engine will start to replenish the battery as needed. However the HV battery could be relatively low just prior to an automatic engine start when you shift to Neutral to go through the car wash.

 

It won't start the engine. If stopped, the engine cannot start while in N. If running, it won't stop in N (unless fuel runs dry), but it can't charge the traction battery either.

Because the Prius drivetrain has no mechanical disconnect, the required Neutral disconnect is achieved by disabling the fields to motor/generators, allowing them to freewheel. No propulsion, no generation. This is a safety requirement.

If you enter the car wash with a low traction battery, the most important thing to turn off is the A/C. If that is intolerable, then bypass the car wash, returning when the battery has a better charge.

Forced charges are possible outside the carwash, but not inside.

 

Or just skip the auto wash completely, its not very good for the finish. Treat your car to a gentle caress with a good wash mitt and some decent car wash juice. The results are superior by far, and it gives you the chance to regularly inspect for chips and dings that need touch-up.

 

You are certainly correct but when you live in the Chicago area, unfortunately with these horrible winters you have to put it through a car wash. Terrible.

 

Before the car wash you can force charge in D with the brakes on, just press the accelerator and all the energy goes to the battery. Once in N it cannot charge, so always minimize time in N. Toyota is required by US law to have an N position, you are not required to use it.

 

FIRST:
Putting your car through an "automatic" car wash means you don't know how harmful it will be (over time) to your car's clear coat finish. It will make it dull with many fine hairline scratches from the grit off other cars that is imbedded in the brushes/cloths.

SECOND:
>Wash your car yourself using quality products like Meguiar's or Mother's.

>Never wash a car with dish washing detergent, only mild auto detergent that will not damage your wax finish.

>Learn the loving and laborious job of the annual "clay bar" job to remove imbedded grit that accumulates over time, especially on the front of the car.

You can still restore your car's finish with a good orbital buffer and some buffing compound. Then wash and wax.

OR NOT...














Learn to wash cars yourself using quality product

 

I live in Chicago. Especially in the winter you have to put your car through an automatic car wash. Washing by hand is impossible.

 

There are some car washes where you drive in and stop. The machinery goes around the car; I'd stick to those: the Prius transaxle cannot be off and in neutral. And running, you can run the hybrid battery run down. Not sure of the ramifications, wouldn't want to find out the hard way.

I haven't used an automatic car wash in decades, but then again the winters are a lot milder here.

 

Okinawa, remember, Chicago has a lot of very upper end cars that never see an automatic car wash. They take them to a hand wash. Yes, it may be $15. a shot at those places but it's worth it.

 

I get having to wash the car, and I get not being able to do it by hand in the winter. Montana is the same situation. I use the car wash with the bay that you spray yourself.
All I've ever gotten from the auto car washes I've done is the opportunity to walk around the car and see the spots that were missed.

 

You can certainly do a better job by hand versus an automatic car wash. No doubt about that.

 

Agree with avoiding automatic and public wand-style car washes. Two cases in point:
1. Bought a 2006 Scion xB in 2009 which had alsways been run through an automatic car wash. The paint was not bad but the glass was etched by the detergents. Many small 1/4" circles all over the glass. Tried various glass cleaners on an experimental spot plus polishing compound but nothing has worked.
2. The same Scion had installed a rear window "decal" advertising my company. I usually wash by hand in the driveway. About three years into the decal's life - it was fading slighly - took to a wand-style carwash and the detergent/power combination washed away the decal's printing. That is some strong soap!
