My girlfriend has a 2000 4runner. She had it at the car wash and when she got back in and drove off she noticed the 4x4 indicator light on the dash was on. The lever had been bumped to the "H4L" position. She moved it back to the "H2H4" position. The indicator light continues to flash..... Why is this light flashing? How do I stop it? BTW, the 4x4 button was not pushed.

 

it doesnt say anything about this in the manual?
