Hybrid System Warning Light blinking only when car off

Next time this happens, pls take some clear photos.

 

Thats not the master caution your referring to it’s the hybrid vehicle immobilizer/theft deteterent system light. Page 7 owners manual.

It always blinks if your alarm system is operational. It’s a red car with a car key sideways on it. Normal.
That’s why there was no diagnosic test codes logged.

Your thinking and referring to the master caution light. When that is thrown on the dash you will know it as it’s very large and bright.

But your right about the hybrid battery. Sometimes not driving the car much is harder on that battery than driving it too much and if your battery is healthy I recommend now is the time to invest in a hybrid battery charger/ discharger which really works great on an old but still kinda healthy battery.
It comes with a cable that must be installed in the hybrid battery and then you just connect the charger
Periodically to charge it or discharge which really wakes the old battery up.
You can tell if the battery is getting tired it will tank to one or 2 purple bars just in a drive through or take a long time to go from one purple bar to blue bars. That and your mileage is terrible.

Use the search forums button up top and search

Prolong charger.

Good luck.

 

If you're talking about this light. I too found out it is normal and flashing across all recent Toyota models.
I never noticed it until a few months ago and it came as a bit of a shock. But it's a normal flashing red light.

 

You own a g4 this is the g2 forum so it looks a little different.

On a g2 it’s a little red blinking car with a key on it sideways. Always blinking with car off. Not recent with Toyota they have been using this for years,

Basicly means the immobilizer is healthy and working waiting for a hand shake from the key fob,
Immobilizer means the car is immobilized until it sees correct rfid from fob.

Light Disappears when car in ready.

 

WHICH symbol

​

and WHERE: each symbol is at a different location.




Learn to check the engine oil level regularly and tire pressure. Many drivers today, can't be bothered to both of those items: oil level, tire air pressure. You can benefit by searching this topic on the Internet and seeing youtube videos.

50K miles on a 2007 is suspect. Low mileage combo meter could have been swapped in or low mileage programed into it. Did you pay for a CarFax report or look-up service history at Toyota.com or inquire at a local dealer? If there was only ONE previous owner, who was elderly, and only drove to church, grocery store, doctors office, and grand kids, 50K would be very believable.

Read the owners manual. Goto Toyota.com and download it if need be.

 

Ceegee made it pretty clear which light it was in the very first sentence. Even if it went away, there should have been a code stored in the history, I would think.

 

Unfortunately, the OP is not clear. The icon described in Jerry's post only appears when the MFD is powered on and the car is IG-ON or READY.

Since the OP says the light in question is blinking when the car is IG-OFF, that caused me and other respondents to wonder if the OP is really describing the theft prevention warning light. Hence my request for a photo so that we can see exactly what the OP is referring to.

 

1) There was the belief that you may have been confused about the exact light (Immobilizer vs Hybrid System Warning). Others felt this same way too, even Patrick Wong. Had you stated Hybrid System Warning light on the MFD (MultiFunction Display)/touchscreen, there would be NO AMBIGUITY. NO SECOND GUESSING.

2) As you may know, many people before you say "A," but upon further questioning/clarification, they actually meant "B." And because of this suspected confusion, I made the errant assumption that you might be a driver who doesn't check their engine oil level and tires. Clearly NOT you. Had you been, it was out of hope that you would start to tires and oil, to avoid becoming #3 below.

3) It is very concerning, that many drivers today, can't be bothered to do the basics (check engine oil and tires) with any regularity (once a month even). And b/c of their laziness, there are more than enough posts where people ask about one or both of these lights:

"Hey this/these light/s comes on intermittently when I brake hard or take a turn aggressively. What does this mean?"
