Porsche 911 Carrera's seat heater automatically turns off

Posted: February 17, 2019 Updated:

I love the Porsche 911 seat heater

In the cold winter, besides using the heater in the car, the seat heater is useful. I love this because it's really warm. It's pretty good in winter.

The sheet mark button inside this yellow circle

  • Press once to poke 3 red lights = seat heater turns on and warmest
  • Press it again and the light will poke 2 = the warmth will weaken a little
  • Furthermore, if you press it again, the light becomes one = the weakest way to warm up
  • Furthermore, if you press it again, the light will turn off = the seat heater will be off.

It will be that.

In the picture below, the seat heater button is pressed only once and the seat heater is set to MAX in a warm state ↓

Normally, by pressing the button several times as described above, the temperature of the seat heater is controlled or turned on / off, but strangely, there are times when this is not the case.

In the cold, I got into the car, started the engine, turned on the seat heater in a good mood, and thought, "Oh, it's getting warmer from the buttocks, the best ~ ^^" I noticed that it wasn't warm, wasn't it cold? ”, And when I looked at the button on the seat heater, NO, oh, the light was off without permission! !! !!

There is something like that. ↓

The 911 seat heater turns off without permission

I haven't touched this button at all except when I turned it on for the first time, and of course I didn't turn off the engine in the middle. However, when I noticed it, there were times when the seat heater was automatically turned off.

I was wondering about this phenomenon, but I thought that I could press the button again, so I thought, "Well, Porsche, I didn't feel like turning on the seat heater yet." I didn't ← It's too techy (laughs).

However!

The other day, when I saw a person with the same problem on an overseas bulletin board proposing a problem at Porsche 911, "Why does the seat heater turn off without permission!", "Oh, this is the same problem as me." I thought, and decided to care ^^.

What was shocking there was the answer that "The Porsche manual says that the seat heater will turn off without permission in two certain conditions." Yeah. Is that so? What was the condition (condition)? ??

Two conditions for the Porsche 911 seat heater to turn off automatically

The written "two conditions for the seat heater to turn off automatically" is

  • Heated seats are not available when the interior temperature is high
  • If the battery voltage is too low, the heated seat / seat ventilation function is initially restricted and then turned off.

what? ?? ?? Well, wait a minute. What is written in the Porsche manuals overseas must be the same in the Porsche manuals in Japanese.

So, I took a look at it. In the Japanese Porsche manual, this is the page where the seat heater is written ↓

As you read this ... a. there were! was. In the last "Information" of the manual part about the seat heater, there is a description of the condition that the seat heater is automatically turned off! !!

Yes, the two conditions are exactly the same as those written in English (it's natural ^^), as follows:

  • The seat heater cannot be used when the room temperature is high.
  • If the battery voltage is too low, the seat heater / heat ventilator will be controlled and then turned off.

I see! People from overseas also asked, "How often is it when the temperature in the room is high ?!" (No clear answer), but in fact, when my 911 seat heater turns off, It's just after I started riding, and it's not so hot in the room, but it's cold and cold.

If the battery voltage is low, the seat heater / ventilator will automatically turn off.

Therefore, in the case of my car, the second thing that the seat heater turns off without permission is that the battery voltage is too low. Yeah, that's okay.

I don't know how difficult the battery voltage is, so what I don't understand is, "Well, it's okay if you press the button again, so it's okay!" I would like to say OK.

I wonder if ... isn't it? ?? As I was writing, I became a little worried ... Hmmm. Next time, I would like to check something incidentally @ Porsche!
