What is this icon on instrument
 

Can not find any info, guess cause I forgot what it is called.
Am out in the boonies so no books/etc
Internet is so slow

Can not find the post

It looks like a car with a key in the middle.
Located below the seat belt icon on cluster guage?
Blinks on and off very fast
Have 06 Shinka with smart key

I know I downloaded that info but can not find it. Misplaced it
TIA

Mine does the same as his.

Edit: NM you edited your post as I was typing mine.

means the battery in your key is low when you turn the ignition on.
if your car is off and its blinking means the immobilizer system is activated.

06 Shinka with smart key
When car is off, IS icon blinks red
When I start the car with or without the key, IS goes off
Car starts and runs fine
When I kill the engine, ie stop it. icon comes back on
so the IS is activated?
So what do I do to fix it, ie get that red flashing icon to not flash
Yes I think the battery in the smart key is low
Was across the border all day ie in Mexico and kept thinking the car would get stranded there but
it ran/started fine.

Will try to find a new battery tomorrow when I go to town.
BTW what is a ETV relay and where abouts is it located?

Installed new battery in smart card and all is well
thanks
